The European Rosalind Franklin Mars rover, part of the beleaguered €1.3 billion (US$1.3 billion) ExoMars program, is now set to launch in 2028, having secured a $360 million investment. euros from European countries.

The money will allow the European Space Agency (ESA) to begin designing a new landing pad to bring its first Mars rover to the planet’s surface. The work is needed after ESA severed ties with its former mission partner, Russian space agency Roscosmos, in March following the Russian invasion of Ukraine. Russia was responsible for designing and building the rover’s landing gear, as well as launching the mission from its site in Baikonur, Kazakhstan.

“I am very relieved and incredibly happy that this great mission has not been taken away from us and that I can continue to hope to one day lead a rover to Mars,” says Daniela Tirsch, planetary geologist at the German Aerospace Center in Berlin. Only the United States and China have placed functional rovers on Mars.

The latest postponement to 2028 is the third in the mission’s history. The ExoMars rover was originally scheduled to launch in 2018, but technical issues derailed that plan. The COVID-19 pandemic then postponed a planned flight from 2020 to 2022, before relations with Russia soured. The cost of the delay from 2020 to 2022 was in the region of 100 million euros, an ESA spokesperson said. Nature.

deep drilling

Despite its delays and mounting costs, scientists remain excited about the ExoMars mission, which is the second part of a program that includes an orbiter that arrived on the Red Planet in 2016 and is searching for the biological or geological origins of methane and other gases.

The Franklin rover carries a 2-meter drill that will burrow deep below the Martian surface to search for preserved evidence of ancient life. “We will be looking for evidence of past life underground for the first time ever,” says Jorge Vago, ESA project scientist for the mission, based at the European Center for Space Research and Technology in Noordwijk, Netherlands. Down.

“ExoMars is a truly incredible mission that will be unique in its method and scientific approach, even if it is launched in 2028,” says Francesca Esposito, planetary scientist at the INAF Astronomical Observatory of Capdiomonte in Naples, Italy, and member of the assignment.

ESA expects NASA to help by providing the mission’s launch vehicle, its braking motor, to be used during landing, and its radioisotope heating units, the director general said. of ESA, Josef Aschbacher, during the press conference after the conference. The latter is necessary for Rosalind Franklin to survive the harsh Martian nights. But European technology will replace the rest of Russia’s lost contribution, he said.

Member States pledged the money for the mission at the ESA Ministerial Conference held in Paris on 22-23 November, where they committed a total budget of €16.9 billion for five-year projects. This includes €2.7 billion for human and robotic space exploration, a 16% increase from the last agreement in 2019, and €3.2 billion for the agency’s science program, i.e. an increase of 19%.

Within this framework, the ministers agreed to fund the Solaris project, a program aimed at determining the viability of the development, from 2025, of a space-based solar energy system that would bring energy to the Earth. Nations around the world are exploring the technology, which would seek to beam power from a solar array miles into orbit and which has become more viable given the falling costs of space launches.

Schematic illustration of the interior of Io with (a) a magmatic sponge and (b) an ocean of subterranean magma. A magnified view of the eruption through the crust is also shown on the right. The parameters defined in sections 2 and 4.1 are associated with the corresponding tanks. Our results suggest that a magmatic sponge would quickly separate into two phases and create an ocean of magma, which is a rheologically liquid layer with φ>0.4. Note that the crust and the partially molten layer are connected by a transition zone, where the rising magma solidifies to heat the collapsing crust (Section 4.2). — astro-ph.EP

Intense tidal heating within Io produces active volcanism on the surface, and its internal structure has long been the subject of debate.

A recent reanalysis of Galileo magnetometer data suggested the presence of a high melting fraction layer with a thickness >50~km in the subterranean region of Io. Let this layer be a magmatic sponge'' with interconnected solid or a rheologically liquidmagma ocean” would alter the pattern of tidal warming and also influence the interpretation of various observations.

To this end, we explore the equilibrium state of a magmatic sponge and estimate the amount of internal heating required to maintain such a layer with a high degree of melting. Our results show that the rate of tidal dissipation in Io is insufficient to sustain a partial melt layer of ϕ > 0.2 for a wide range of parameters, suggesting that such a layer would rapidly separate into two phases.

Unless the melt and/or solid viscosities are at the upper end of the estimated range, a magmatic sponge would be unstable, and thus a high melting fraction layer suggested in Khurana et al. (2011) is probably an underground magma ocean.

The critically acclaimed film hidden numbers (2016) have drawn public attention to important aspects of NASA’s history. Based on the book of the same name by Margo Lee Shetterly, the film dramatized the real-life stories of three African-American mathematicians – Katherine Johnson (Taraji P. Henson), Mary Jack Jr. (Janelle Monáe) and Dorothy Vaughn (Octavia Spencer) — who worked at the aeronautical research center that became NASA’s Langley Research Center.

Space Craze: America’s enduring fascination with real and imagined spaceflight

From the 1929 debut of the futuristic Buck Rogers to today’s privatization of spaceflight, Passion for space celebrates America’s endless enthusiasm for space exploration. Author Margaret Weitekamp, ​​curator at the Smithsonian’s National Air and Space Museum, writes with warmth and personal experience to guide readers through the extraordinary history of spaceflight while showcasing artifacts from the National Air and Space Museum’s spaceflight collection. Smithsonian.

They began their careers as human computers, a mathematical equivalent of the secretarial pool used in many research centers at the time. Unlike the young male engineers, however, the female computer scientists were doing their job with no hope of career advancement beyond their current job. At Langley in Hampton, Va., those jobs were also segregated by race. The award-winning film took a few liberties with historical accuracy, but it brought widespread recognition to the remarkable careers of women. Johnson, Jackson and Vaughn all made important real contributions to the space program: Johnson calculated rocket trajectories and orbital trajectories, publishing his technical findings; Jackson became NASA’s first black female engineer; and Vaughn, the first black woman to serve as a supervisor at Langley, also helped program the center’s first mechanical computers.

This story was not unknown. After all, President Barack Obama awarded Katherine Johnson the Presidential Medal of Freedom in November 2015, before the film and book were released. And NASA announced a few months before the film was released that a new building in Langley would be called the Katherine G. Johnson Computational Research Facility. But the film’s popular reception has greatly increased awareness of their story. Perhaps more importantly, the term “hidden characters” became shorthand for stories that had been forgotten (or previously ignored or dismissed), giving people a way to name those whose work had been largely ignored.

The time seemed right to celebrate the women of NASA. In April 2016, Nathalia Holt published The Rise of the Rocket Girls, telling the story of the women working at the Jet Propulsion Laboratory since its beginnings. Still at the beginning of 2016, months before hidden numbers came out, Maia Weinstock, an MIT science writer and Lego enthusiast, began designing a set of figurines or “minifigs” of notable NASA women.

Weinstock was particularly sensitive to stories of women she thought were underappreciated, such as astronomers or engineers. Weinstock created the minifigures and their miniature scenes using a technique called “kit bashing”: combining or modifying existing parts from many different Lego sets. She also used Minifigs.me, a company that creates custom minifigures. In the end, her set of prototypes represented five women, including fellow MIT engineer Margaret Hamilton, who developed software for the Apollo lunar guidance system, and Nancy Grace Roman, NASA’s first chief of astronomy and the an early proponent of the Hubble Space Telescope. Posed on their small stages, each minifig evoked famous photographs of real women. Mathematician Katherine Johnson was shown working at her desk. Sally K. Ride, the first American woman in space, and Mae Jemison, the first African-American woman in space, stood on either side of a space shuttle orbiter.

Weinstock created the set to enter an ongoing contest on the Lego Ideas website, where it met with popular success. Her entry, titled “Ladies Rock Outer Space,” included photographs and descriptions of her creations. According to the website’s rules, suggestions that receive ten thousand online votes are considered by Lego for production, although adoption is not guaranteed. As she promoted her entry on social media, online articles quickly picked up the story and well-known stars boosted her visibility. It also received some unexpected celebrity endorsements. Musician Pharrell Williams, producer of hidden numbers, tweeted about it, as did Jemison herself. Janelle Monáe put it on her Instagram. Some interviewees expressed a wish that they had had a toy like this, showcasing prominent women, when they were growing up. The Girl Scouts Twitter account tweeted about the potential set. In less than two weeks, Weinstock’s entry reached the required ten thousand votes. Over the next year, the Lego design team crafted the final 231-piece retail set, which was released in November 2017. The three versions included in the final set captured the spirit of creation. from Weinstock with a slightly different execution from the final concepts. The final set did not include Katherine Johnson’s minifigure as she declined to participate.

Popular response to the highly anticipated original Lego set revealed that customers were eager to embrace historical figures that had long been overshadowed. At the Lego store in Manhattan, customers lined up for the kit’s first day of sales. According to CNN.com, in its first twenty-four hours on sale, the Women of NASA Lego playset became the top-selling toy on Amazon. The kit tapped into a contemporary interest in reclaiming the history of women in science, technology, engineering and math (STEM) and promoting these fields to young women and girls. The importance of women to spaceflight was seen as important in celebrating past accomplishments and inspiring the next generation.

NASA leadership had its own vested interest in reclaiming women’s contributions to the agency to redefine its future. In 2019, NASA renamed the street outside its headquarters in the nation’s capital “Hidden Figures Way”. In 2020, NASA held a separate ceremony to name the building Mary W. Jackson Headquarters. These public recognitions of black women who supported NASA
early accomplishments were consistent with the stated goals of NASA’s Artemis program.

Artemis, which was announced in late 2017, refocused NASA’s human spaceflight exploration targets. Rather than pursuing, in order, the ambitious triple destinations of Earth (ISS), the Moon, and then Mars, as previously planned, Artemis focused on getting humans back to the Moon. Initially, the goal was to bring a man back and send the first woman to the lunar surface. As reworded, however, the program’s goals became more focused: “to land the first woman and first person of color on the Moon”. The program’s name, Artemis, after Apollo’s sister, both recalled the heyday of the moon landings and looked forward to the planned inclusion of women. NASA promised that Artemis would be “the largest and most diverse international human space exploration program in history”.

The first all-female spacewalk was in October 2019, when Christina Koch and Jessica Meir performed scheduled work outside of the ISS. NASA cited the event as evidence of greater female representation in all aspects of space and investment in future exploration. As a report on NASA’s website reminded readers that Koch and Meir are carrying on “a tradition that dates back to our earliest days,” citing, by name, Katherine Johnson, Dorothy Vaughn and Mary Jackson as well as the chief of the astronomy Nancy Grace Roman and Apollo orientation computer software engineer Margaret Hamilton. NASA’s public commitment to include the first woman and first person of color in the next human moon landing will require supporting a diverse astronaut corps in ways large and small.

As winter sets in for Ukraine, ARKX is ready for drone orders https://jenam2011.org/as-winter-sets-in-for-ukraine-arkx-is-ready-for-drone-orders/ Mon, 14 Nov 2022 19:44:47 +0000 https://jenam2011.org/as-winter-sets-in-for-ukraine-arkx-is-ready-for-drone-orders/

No other event impacted the markets this year like the Russian invasion of Ukraine. The Russian military launched a new offensive this week ahead of Ukraine’s liberation of previously occupied Kherson. As winter looks set to harden the battle lines, investors looking for a drone ETF should take a close look at the ARK Space Exploration and Innovation ETF (ARKX) and its third holding AeroVironment (AVAV).

AVAV received an analyst upgrade from Raymond James late last week due to a ramp-up in orders over the past few months, highlighted by news on Thursday that the U.S. military awarded a $86 million contract to the company.

AVAV’s unmanned aerial vehicles have played a notable role in US efforts to support Ukraine against Russia, increasing demand for their reconnaissance and surveillance capabilities. This surge in demand has manifested itself in its share price, which has risen 6.6% in the past five days and 20.2% in the past month, compared to just 15.6% in the past. of the last six months.

ARKX, which owns AVAV at 7.3% behind autonomous agricultural vehicle company Trimble Inc., (TRMB) and Iridium Communications Inc. (IRDM) at 10.3% and 7.7% respectively, invests in global companies working in orbital and suborbital aerospace.

Due to its narrow technology focus on companies working in spaces that can support space exploration like robotics, materials, and 3D printing, it can augment rather than replace a core technology portfolio. Add to that its recent uptick in performance, with a one-month return of 10.3% versus -13.3% over the past three months, and it can be a handy addition to a bullish investor’s portfolio.

For just over a year, after launching in March last year, ARKX has been charging a 75 basis point fee for exposure to its holdings and strategy. As investors reinvest in the sequel to ARK Invest through other strategies like the flagship ARK Innovation ETF (ARKK)investors may want to follow ARKX and its growth potential as demand for drones increases for Ukraine and its allies.

Tumwater’s wife, key planner for NASA’s Artemis 1 Moon mission – KIRO 7 News Seattle https://jenam2011.org/tumwaters-wife-key-planner-for-nasas-artemis-1-moon-mission-kiro-7-news-seattle/ Fri, 11 Nov 2022 20:04:07 +0000 https://jenam2011.org/tumwaters-wife-key-planner-for-nasas-artemis-1-moon-mission-kiro-7-news-seattle/

SEATTLE — In a few days, we hope to see the launch of the Artemis 1 rocket for a trip to the Moon.

NASA had to delay the last launch due to Hurricane Nicole making landfall on the east coast of Florida.

The launch is scheduled for Tuesday, November 16 at 10:04 p.m. PT.

One of the mission’s main planners is Nujoud Merancy, a native of Tumwater, NASA’s chief of exploration and mission planning. Merancy works with a team to coordinate all elements of NASA missions, including Artemis 1. Merancy sat down with KIRO 7’s Ranji Sinha in the studio before the final launch attempt.

Here are some of the questions and answers edited for brevity.

Ranji: I am Ranji Sinha here at KIRO 7 studios joined by Nujoud Merancy from NASA. Please join us here in person. I spoke to you on Zoom, but it’s nice to meet the woman behind the mission.

Nujoud: One of many.

Ranji: Nujoud, first of all tell us your official title with NASA.

Nujoud: Right now, I’m the head of the exploration mission planning office at Johnson Space Center, so we’re the team that set up and integrated the mission.

Ranji: Nujoud, I’m sorry, I’m just so frustrated — rubbed (launch) again! Pushed and delayed again! This time because of a hurricane!

Nujoud: It happens, right? We launch over the ocean for a reason, so you’re safe, you’re away from it all, but it puts you at the mercy of Florida hurricanes. Unfortunately that’s what happened this time, but hopefully we’ll be ready to go again very soon.

Ranji: Why are we going back (to the moon)? What is our goal?

Nujoud: We return to the Moon for many reasons. There are three main categories: first, scientific interest. The ability to study the Moon, to study the processes on the Moon, to study the things that have impacted the Moon over time.

Nujoud: The technology developing these systems is very difficult. We tend to push the limits of technology, and this technology also returns to benefit the Earth.

Nujoud: Third, just the economic benefit of going, driving programs and all the amazing companies working in the aerospace industry today. It stimulates the economy, so many different reasons.

Ranji: The Apollo missions went to visit the Moon. We visited. This time we will stay. Is it correct?

Nujoud: It’s correct. Artemis 1 is the first of we hope to be many decades of space exploration. So starting with the Moon, building the cislunar platform systems for our gateway orbit lab and the surface systems so we can do deep space exploration…to go to Mars and continue the space exploration.

It’s not necessarily about going to the Moon and then going to Mars. It would actually cost more performance, thruster, things like that. But many of the systems we need on Mars are analogous to what we need on the Moon. Nuclear fission energy, potentially long-lived habitation. Much of the technology we develop for the Moon would then be useful for Mars. We can do a lot of work on these lunar missions to feed into the Mars missions down the road.

Ranji: How is it going for you, with your team, up to this point to throw?

Nujoud: We have a rocket, a space launch system, we have an Orion spacecraft, we have ground exploration systems, which is the Kennedy Space Center. recovery teams. Putting all of these pieces together is really mission planning. Where are we going how long and why. So our team is actually working with all the programs in all the centers to bring together what is the mission that we do. We make sure that it is a pilotable mission, for example.

Ranji: So no pressure — little stress?

Nujoud: It’s literally magic.

Ranji: You are from our region. You grew up in Tumwater.

Nujoud: That’s right Tumwater, Washington.

Ranji: How were you inspired to join NASA?

Nujoud: I always loved airplanes, spaceflight, reading about Apollo as a kid – really science and engineering in general. Growing up, I really wanted to get into aerospace. I went to the University of Washington and you graduated and you can get jobs in this industry right out of college. That’s what I did. I first started working on the space station, the International Space Station out of college, and moved to Houston, Texas.

Ranji: This one (attempted launch) will potentially be a night launch and that’s cool. Tell people why, because a lot of people like you have said, “Oh, I can’t see him during the day.” Why is it cooler?

Nujoud: Literally, the launch time is based on where the Earth has rotated and where the Moon is. I actually like night launches a lot because you see that engine running around for a long, long time. If you’re in a daytime launch, you’ll lose sight of it after a few minutes out of the pad. It’s really exciting. I’m sure my stomach will churn.

Ranji: Tricky question: Come on, when are we getting to Mars? What is the year, what time is it?

Nujoud: There are so many systems we need to build and develop that I’m not going to commit to a year. Hopefully by the 2030s we have built all the systems to get to Mars.

Tencent’s WE Summit Dialogue on James Webb Space Telescope and Space Exploration Inspires Next Generation of Scientists and Astronomers https://jenam2011.org/tencents-we-summit-dialogue-on-james-webb-space-telescope-and-space-exploration-inspires-next-generation-of-scientists-and-astronomers/ Mon, 07 Nov 2022 00:02:42 +0000 https://jenam2011.org/tencents-we-summit-dialogue-on-james-webb-space-telescope-and-space-exploration-inspires-next-generation-of-scientists-and-astronomers/ In July 2022, the first images from the James Webb Space Telescope (JWST) were released, causing a sensation. The infrared photos showed planets, stars and galaxies in unprecedented detail, going viral online and still making headlines around the world.

With an interest in science and astronomy at its peak, we have organized an international dialogue on deep space at the Tencent WE Summit 2022. Now in its 10th year, the summit serves to shine a light on the most ambitious scientific work being done around the world.

Distinguished speakers at this dialogue included Nobel Laureate Dr. John C. Mather, Senior Project Scientist at JWST; Dr. Zhan Hu, Project Scientist for China Space Station Telescope Optical Facility (CSST), Chinese Academy of Sciences; and Dr. Deng Dafu, Deputy General Manager of Tencent IEG Cros and AI expert for the CATCH program.

In the spirit of collaboration that underpins the Summit, this is the first dialogue between the three programs. They were accompanied by a student and amateur astronomer, Zhou Zezhen, winner of the Young Astronomical Photographer of the Year category by the Royal Observatory Greenwich.

The dialogue was moderated by Professor Gou Lijun, a researcher at NAOC.

Various Srhythm Pprograms, Complementary Missions

The JWST, with a diameter of 6.5 m, is the largest optical telescope in space. Launched on December 25, 2021, the telescope is a joint project involving 20 countries and uses infrared photography to study light from distant universes. Dr. Mather says that “he observes everything from the first stars and galaxies and black holes to the planets of the solar system”.

The launch of the CSST – a two-meter-aperture wide-field space telescope – is scheduled for a year or two in the same low Earth orbit as the Space Station. Dr. Zhan explains that the CSST’s primary mission is “to perform high-resolution, large-area, multi-band spectral and imaging surveys using what will be the largest camera in space.”

Meanwhile, CATCH will launch a fleet of smart satellites equipped with X-ray telescopes to observe multiple space phenomena such as black holes, neutron stars, gamma-ray bursts and supernovae. The satellites use AI calculations to make observations and notify other satellites in the fleet to monitor a target around the clock if anything of interest is detected.

Frontier Technology Brings Complex Challenges

Building the JWST presented unique challenges that took years to overcome. Dr Mather describes it as an “origami telescope” due to the way it had to be folded for launch. The engineering was “extremely ambitious” and required the development of 10 new technologies to focus the telescope after launch, assemble the telescope from 18 hexes, ensure the sunshades worked, and invent new types of infrared detectors. .

“We had to design it, build it and test it, and when it didn’t work, we had to start all over again. Finally, after four tests, it worked,” says Dr. Mather.

For the CSST which has not yet been launched, the project team is working to finalize the mission parameters. They have not yet determined which celestial objects will be observed and how to disseminate the large amount of data that will be collected. According to Dr Zhan, The CSST is primarily a surveying telescope. It can be used to observe nearby galaxies such as M31, a very beautiful and large galaxy, and nearby dwarf galaxies as well as galaxy clusters. Similar to the JWST, the CSST can use galaxy clusters to study strong lensing effects, and Zhan’s team expects to get stronger observations next year.

CATCH uses reinforcement learning to help the AI ​​solve long-standing puzzles. However, it must first perform intensive testing to overcome the high training and deployment costs, limited interpretability, and lack of learning, historical experience, and data that underpin the algorithms.

Go where no human has gone before

Each project solves problems and uses technology that allows astronomers to see and do things for the first time and to learn things that have long puzzled mankind.

The JWST uses infrared to see the outermost universes, or objects too cold to emit visible light, and inside the glowing clouds of gas and dust where stars are born.

This allowed the JWST team to observe planets around other stars and learn that some planets have water vapor in their atmosphere. They observed black holes and star-forming regions, including the spectacular Carina Nebula.

Compared to ground-based telescopes, the CSST will have the advantage of high angular resolution and wavelength coverage, as well as a large sky coverage area of ​​one square degree. It may not seem like much, but gives CSST a high-resolution field of view that’s 10,000 times larger than a ground-based optical telescope.

We know that gaming technology has real world apps. Now we can see how this can help deep space exploration. The CATCH project uses game AI developed by Tencent Games to help satellites estimate the space environment and make observations in an intelligent and coordinated way. It does this by treating celestial objects as agents and applying corresponding algorithms to find an optimal solution.

A platform for the next generation of scientists and astronomers

Zhou Zezhen, a Chinese high school student, showed a good understanding of astronomy and asked probing questions to the senior panel. He asked Dr. Mather a question about how the JWST studies black holes, dark matter and dark energy, given that they are effectively invisible.

Dr. Mather replied that the JWST can detect their presence through gravitational effects. The gravity of galaxies bends light, indicating the presence of dark matter, which is inferred rather than observed, allowing us to know about distant galaxies.

Clever questions were also directed to Dr. Zhan about the advantages of CSST over existing ground-based telescopes, and Dr. Deng about how he came up with the idea of ​​applying gaming AI to a space mission and how train the AI ​​for such a mission.

Make an impact and help Scientific Development Through the exchange of ideas

With the launch of CSST on the horizon, Dr. Zhan and other scientists were eager to hear Dr. Mather’s ideas on how to maximize the impact of the project and the huge investment to get it off the ground.

Dr. Mather’s answer was clear and simple: “share the data and ask for help”. He went on to explain that “the more you can publish your data and have it analyzed by other people, the more interesting it will be”.

He explained how the effort and skill required to build a telescope or observatory are different from those required to analyze data and make interesting discoveries, and JWST is open to proposals and partnerships from any astronomer or scientist around the world. entire.

Dr. Mather also addressed a message to young people like Zhou, saying that astronomers have a broad understanding of physics and engineering, which makes them highly qualified for scientific and technical fields, especially in the analysis of data.

He concluded on an optimistic note, reflecting the current enthusiasm for science and astronomy. “It’s a very exciting time to be an astronomer because we have new equipment, which means new discoveries.” With them, “many, many things are possible”.

Besides this dialogue, the WE Summit 2022 also hosted several dialogues between Chinese teenagers and Thomas Lindahl, winner of the Nobel Prize in Chemistry, and considered the father of DNA repair; Jiang Peng, researcher at NAOC and chief designer of China Sky Eyethe five hundred meter aperture spherical radio telescope (QUICK); and other scientists. Such discussions inspired the next generation of students to research, reflect and pursue science.

More than 80 of the world’s top scientists have attended the WE Summit in its 10-year history. They shared cutting-edge scientific and technological information with the public, including theoretical physics, astronomical exploration, brain-computer interface, quantum computing, life science and other fields.

Research center to develop space food expertise https://jenam2011.org/research-center-to-develop-space-food-expertise/ Thu, 03 Nov 2022 23:46:00 +0000 https://jenam2011.org/research-center-to-develop-space-food-expertise/

A new research centre, led by the University of Adelaide, will focus its international expertise on finding ways to provide the next generation of space explorers with nutritious food and the on-demand supply of materials and of drugs.

Announced today, Friday 4 November, the Australian Research Council’s (ARC) Plants for Space (P4S) Center of Excellence will help establish a long-term human presence in space, while developing innovations on Earth.

The Australian government is providing $35 million in funding for the new centre, which will initially last seven years. Additional cash and in-kind support from the 38 P4S partners brings the total value to approximately $90 million.

“P4S’s mission is to reinvent plant design and bioresource production, through the lens of space, to enable above-Earth habitation and provide transformative solutions to improve sustainability on Earth,” said the Professor Matthew Gilliham, Principal of the University of Adelaide. of the new center of excellence.

“P4S research will create the flexible plant-based solutions needed to support human physical and psychological well-being during deep space travel and settlement.

“The work undertaken by Center experts will also bring about a step change in the efficiency, productivity and processing technologies of factories here on Earth.”

P4S is a major global collaborative transdisciplinary enterprise that brings together 15 academic institutions, five space agencies and enablers, five controlled environment agriculture (CEA) companies, six education providers, and seven government and technology partners who collectively leverage a global critical mass adapted to the objective not found elsewhere. Australia University’s founding partners are the University of Adelaide, University of Melbourne, University of Western Australia, Flinders University and La Trobe University.

“Long-term off-Earth habitation is on the horizon. However, major challenges remain, which will be addressed head-on by P4S. Mission success depends on the availability of nutritious food and medicine without having to need for resupply missions from Earth,” said P4S Plants program manager Professor Harvey Millar of the University of Western Australia.

P4S will also drive transformational benefits for industries on Earth and sustainability outcomes. P4S breakthroughs will offer new plant efficiency solutions for harsh terrestrial environments and work on how to intensively, yet sustainably, produce plant-based foods that can reduce the carbon footprint of agriculture.

“Space habitation amplifies the multi-faceted sustainability challenges we face in producing food and biomaterials on Earth,” said Dr. Kim Johnson, P4S People Program Manager, La Trobe University.

“The collective multidisciplinary expertise within P4S will lead innovation in space plant production systems and realize the Center’s multi-faceted heritage to fulfill humans’ ambition to explore beyond Earth.”

P4S will expand Australian leadership, collaboration and capacity in space-inspired plant and food research.

“National and global interest in extraterrestrial exploration provides P4S experts with the opportunity to build on South Australia’s space leadership and Australia’s reputation in space research,” said Professor Anton Middelberg, Deputy Vice-Chancellor (Research), University of Adelaide.

“Integrated, globally connected and transformative research programs will fill gaps, drive sector coordination, strengthen the workforce and innovate with industry-ready solutions.”

P4S will be an Australian contribution to NASA’s Artemis Accords, which have been signed by 21 countries, including Australia. The Artemis mission plans to put the first woman and person of color on the Moon by 2030 and develop the technologies needed for humans to venture to Mars and return to Earth in the 2040s. should be launched and return to Earth by the end of 2022.

The head of the Australian Space Agency, Mr Enrico Palermo, said: “As humanity seeks to return to the Moon, this time we are doing so with the aim of establishing an enduring presence that will allow us to explore further than ever.

“Many challenges are associated with ensuring that humans can live sustainably on the Moon. P4S is just one way Australia can help achieve this goal as part of its commitment to the Artemis Accords.

“We are excited about the possibilities this brings and the opportunities it creates for our growing space sector.”

Why Monuments and Symbols of Nazi Collaborators Are All Over America – ARTnews.com https://jenam2011.org/why-monuments-and-symbols-of-nazi-collaborators-are-all-over-america-artnews-com/ Tue, 01 Nov 2022 12:02:00 +0000 https://jenam2011.org/why-monuments-and-symbols-of-nazi-collaborators-are-all-over-america-artnews-com/

Walk down Broadway in New York’s Financial District and you’ll see hundreds of black granite slabs honoring every ticker parade in the city’s history. There are named winners of the parade like beloved 20th century icons Amelia Earhart and Nelson Mandela, as well as more ignominious figures, in particular Marshal Henri Philippe Pétain and Pierre Laval.

Pétain and Laval, leaders of the Vichy France Nazi collaboration, were honored in parades in the 1930s, years before they adopted policies that removed Jews from public office, seized Jewish property and deported more than 65,000 Jews to Nazi camps. And yet, memorial plaques in New York City weren’t installed until 2004. There are nearly a dozen streets in the United States named after Pétain, who was originally honored as a hero of WWI.

In 2018, the New York City Council voted against removing the Pétain and Laval plaques to avoid what they called “cultural amnesia.” Meanwhile, Canada renamed Mount Pétain in the Canadian Rockies last year, and France no longer has any memorials to either man.

Pétain and Laval are far from the only Nazi and Fascist collaborators to be honored in the United States, or abroad for that matter. In January 2021, a survey conducted by the front identified more than 1,500 statues and streets honoring Nazi collaborators around the world. In the United States alone, there are at least 37 such monuments.

There are, of course, monuments, plaques and statues to many other disreputable or disgraced figures in the United States, from Confederate generals to colonialists and slave traders. In 2020, during the George Floyd protests, these statues became a focal point as activists tore them down or worked to have them legally removed. Yet, in most cases, public art commemorating fascists – and therefore whitewashing fascist history – remains in place. And many, like the Pétain and Laval plaques, have been installed in recent decades.

Understanding why can help make sense of far-right revisionism, which has lurked beneath the surface in the United States for decades and recently exploded into public view.

  • Supervised by NASA astronauts and top scientists, students aged 12 to 18 joined the class in multiple locations of Innoventures Education schools
  • As part of the lesson, students designed a rover to help humans survive and thrive on Mars.

Dubai, United Arab Emirates: Thousands of Dubai students from Innoventures Education schools have achieved the Guinness record for ‘the world’s largest space exploration lesson across multiple sites’. In another historic moment for Dubai, 2,299 students representing 108 nationalities from Dubai International Academy Emirates Hills, Dubai International Academy Al Barsha, Raffles World Academy, Raffles International School and Collegiate International School completed the lessons from their classrooms.

Poonam Bhojani, CEO of Innoventures Education, said, “Innoventures Education has always believed in providing world-class education. Bringing NASA astronauts and world-renowned scientists to Dubai to mentor our students is in line with this vision. We are so proud of all of our students who participated in this record-breaking lesson; and we hope it was a memorable and rewarding learning experience.

Students were mentored by famous names in space exploration and science, including Commander Susan Kilrain, a veteran astronaut on two Space Shuttle flights; Dr. Michaela Musilova, astrobiologist, analog astronaut and writer; Joel Gilmore, professional science communicator; Michael Holmstrom, CEO and co-founder of STEM Punks Ventures; and Damien Aldridge, Education Director of STEM Punks.

Hitesh Bhagat, Director of Dubai International Academy, Emirates Hills, said: “We are thrilled to see our students enter the record books with truly incredible achievement. As educators, we can hope that being mentored by world-renowned people will also inspire our students to aim for the stars. Our intention with this initiative was to create an immersive and experiential learning environment for our students.

Mars rovers like Opportunity and Perseverance were designed for exploration, but once humans arrive on Mars, what kinds of jobs will the rovers need to do? Would they do more exploration? Or build, transport and mine ice instead? What would they look like to be able to do this work? ​Applying their design thinking skills, Innoventures Education students designed their versions of the Mars rovers during the lesson and peer-reviewed them. Then they will prepare the prototype of the rover.

This unique lesson took place during Space Camp 2101. Innoventures Education has partnered with award-winning company Starlight Education to offer students aged 12-18 the unique opportunity to design a sustainable habitat with real astronauts and scientists high level from all over the world. world. Space 2011 was held from October 17 to 21 at DIA Al Barsha. The five-day program helped students develop critical thinking, leadership and teamwork, presentation skills, new STEM skills as well as in-depth knowledge of designing spatial habitats suitable for well-being. To be human.
