North Pole could become a host site for a “satellite earth station,” as part of Elon Musk’s SpaceX plan to develop a global Internet network that reaches remote communities in Alaska and around the world.

SpaceX Services Inc. has filed an application with the Federal Communications Commission to develop an earth station to support the company’s Starlink Internet network, a global satellite system project for the broadcast of high-speed broadband Internet service. .

“Starlink is really for those who are least served,” Musk said in a tweet about his goals for the Internet service.

Other companies trying to bring the internet to communities where it’s a challenge include Alaska-based Pacific Dataport, which works with OneWeb, and Amazon’s Kuiper Systems.

Competition to provide broadband satellite service would help reduce the digital divide between connected communities and sparsely populated areas without access.

In its FCC application, SpaceX identified “Fairbanks, AK” as the site of an earth station. SpaceX has also considered earth stations at Ketchikan and Nome.

According to the coordinates provided on the FCC’s request, the earth station site is vacant land on or near an existing satellite tracking facility at the North Pole, in the borough of Fairbanks North Star. This facility is managed by the American division of the Global Swedish Space Corp., or SSC Space US

The News-Miner asked SSC Space US if the company is partnering with SpaceX for the earth station.

Anni Bölenius, Head of Communications, said this week: “It is correct that SSC Space US owns and operates a satellite station at the North Pole, but we are not commenting on any activity at the station.”

FCC approval required for the station

FCC authorization is required for SpaceX to operate a transmitting satellite earth station.

The applicant must specify the frequency bands and satellites to be used by the earth station, the antenna diameter and the proposed power and power density levels, the FCC said in an emailed statement to News-Miner. .

“SpaceX Services is seeking clearance for a new Ka-band gateway earth station located in Fairbanks, AK,” according to the FCC app.

Local zoning rules allow communication facilities without a zoning permit, said Christine Nelson, who heads the community planning department for the Borough of Fairbanks North Star.

SpaceX sets up earth stations, also known as ground stations, around the world to communicate with its satellites. Satellites fly in low earth orbit to enable faster internet service because the signal has a shorter distance to travel. Earth station antennas are remotely controlled to transmit and receive data, according to the FCC application. Earth stations are linked to data centers that connect to the World Wide Web.

“SpaceX is eager to connect sites on Earth where the Internet connection is unreliable and non-existent,” according to Tesmanian, who reports on SpaceX and other Musk companies.

Global internet service for consumers around the world

SpaceX launches thousands of satellites to provide global Internet service.

In January, a rocket carried 10 satellites into polar orbit, as part of a test and development phase to facilitate Internet access in remote areas including Alaska. This week, the FCC granted a request for SpaceX to fly 2,814 satellites into a lower orbit, allowing faster Internet service in the Arctic region.

Several Alaskan individuals, businesses and organizations have submitted letters requesting approval from ‘SpaceX to begin deployment of its Starlink service in Alaska,’ the FCC said in an order and clearance issued April 27.

Consumers in remote areas of Alaska, including members of tribal communities, discussed “the scarcity of reliable Internet service, the extreme expense of available Internet service, the difficulties in maintaining this service and the that this has on the communities of Alaska, ”according to the FCC mentioned.

“They say the Starlink service will finally bring ubiquitous Internet connectivity to these regions.”

The Starlink Internet network, which is in beta mode, is operational in many parts of the United States and abroad.

Consumers can access unlimited broadband and broadband service, for $ 100 per month, after the initial purchase of a small dish with a WiFi router, bracket, and cables for $ 500, which the company ships to subscribers. .

In February, Government Technology reported that Starlink was allowing Alaskans to sign up for the service, ahead of delivery, scheduled for 2022.

“Starlink is ideally suited to regions of the globe where connectivity has typically been a challenge,” according to the Starlink website.

“Not limited by traditional ground-based infrastructure, Starlink can provide high-speed, high-speed Internet access to places where access has been unreliable or completely unavailable.”

Berkshire Hathaway (BRK-A, BRK-B) CEO Warren Buffett has message on the insurability of Elon Musk’s future SpaceX missions. “It would depend on the premium,” the Oracle of Omaha joked Saturday at Berkshire’s annual meeting of shareholders, broadcast live exclusively on Yahoo Finance.

During an extensive question-and-answer session with Buffett and Berkshire Hathaway VPs Charlie Munger, Ajit Jain and Greg Abel, a shareholder asked whether the conglomerate would be open to an Elon call. Musk with a SpaceX insurance claim. future mission and colonization of Mars.

The question was directed to Jain, who is in charge of Berkshire’s insurance business and is seen as a possible frontrunner to succeed Buffett as CEO.

“Specifically, he wants insurance to insure SpaceX’s heavy rocket, capsule, payload and human capital,” the shareholder said of the hypothetical claim.

Without hesitation, Jain replied, “It’s easy. No thanks. I will come.”

Buffett, who loves Musk is one of the richest people in the world, joked that he would be more willing to ensure SpaceX’s goal of landing humans on Mars, he promised to do by 2024.

“Well, I would say it would depend on the premium. And I would say that I would probably have a somewhat different rate if Elon was on board, or not on board, ”added Buffett, referring to the famous CEO of SpaceX and the electric car company Tesla (TSLA).

Buffett continued, explaining why his fare would change based on adding Musk to the mission’s passenger list, “No, that makes a difference! If someone asks to insure something … that’s called having skin in the game. “

However, Jain wasn’t going to let the storyline end without asserting his more conservative approach. “In general, I would be very concerned about drafting an insurance policy where Elon Musk is on the other side,” he joked.

“Tell Elon to call me instead of Ajit,” Buffet said with the last word.

While Berkshire Hathaway owns 100% or owns stakes in companies in a number of industries, from technology to fast food to underwear, insurance is one of its “jewels of”. family ”and“ the heart of Berkshire, ”Buffett said in his annual letter to shareholders this year. .

For his part, Musk and his companies continue to push the boundaries, getting into trouble with federal regulators on Tesla’s autonomous driving technology and SpaceX’s rocket launches. While NASA awarded SpaceX a contract last month for a lunar spacecraft, Musk’s company was briefed on Friday put the project on hold while rival bidders dispute the contract.

SpaceX makes the news during the day after the Berkshire meeting. Early Sunday morning, SpaceX successfully returned a group of international astronauts to Earth in the company’s Crew Dragon “Resilience” capsule. The four astronauts landed in the Gulf of Mexico near Panama City, Florida, after spending about six months on the International Space Station.

SpaceX: Elon Musk’s Dragon capsule returns to Earth after pioneering NASA mission https://jenam2011.org/spacex-elon-musks-dragon-capsule-returns-to-earth-after-pioneering-nasa-mission/ https://jenam2011.org/spacex-elon-musks-dragon-capsule-returns-to-earth-after-pioneering-nasa-mission/#respond Sun, 02 May 2021 11:37:54 +0000 https://jenam2011.org/spacex-elon-musks-dragon-capsule-returns-to-earth-after-pioneering-nasa-mission/

SpaceX’s Dragon capsule – and the Nasa Crew-1 mission it was carrying – returned safely to Earth after a trip to the International Space Station.

It was the first official crew to make this trip in a SpaceX spacecraft, as the name suggests, although the astronauts made the same trip in the final test. It was also NASA’s first night-time landing since the Apollo 8 mission in 1968, with difficult conditions in recent days forcing the initial arrival times to be delayed.

The Dragon capsule parachuted into the Gulf of Mexico off Panama City, Florida just before 3 a.m., ending the second astronaut flight for Elon Musk’s company.

It was an express trip home, lasting only 6.5 hours.

The astronauts, three Americans and one Japanese, entered the same capsule – named Resilience – into which they were launched from NASA’s Kennedy Space Center in November.

Their 167-day mission is the longest for astronauts departing from the U.S. The previous record of 84 days was set by the final crew at Nasa’s Skylab station in 1974.

Saturday night’s undocking left seven people at the space station, four of whom arrived a week ago via SpaceX.

“Tied to the earth!” NASA astronaut Victor Glover tweeted after leaving the station. “One more step towards family and home!”

Glover – along with Mike Hopkins and Shannon Walker of NASA and Soichi Noguchi of Japan – should have returned to Earth last Wednesday, but strong offshore winds forced SpaceX to pass up two daytime landing attempts. The managers went through a rare splashdown in the dark, to take advantage of the calm weather.

SpaceX had been practicing for a nocturnal comeback, just in case, and had even retrieved its most recent cargo capsule from the Gulf of Mexico in the dark. Infrared cameras tracked the capsule as it re-entered the atmosphere; he looked like a bright star crossing the night sky. The four main parachutes could be seen deploying just before the splash, which was also visible in the infrared.

Apollo 8 – NASA’s first flight to the moon with astronauts – ended with a pre-dawn dive in the Pacific near Hawaii on December 27, 1968. Eight years later, a Soviet capsule with two cosmonauts ended up in a dark and partially frozen lake in Kazakhstan. , deviated from its path in a snowstorm.

That was it for the nightly crew splash – until Sunday. Despite the early hour, the Coast Guard was ready to enforce an 18 km zone of protection around the Dragon capsule.

For the SpaceX crew’s first return in August, boaters invaded the capsule, a safety risk.

Once aboard the SpaceXrecovery ship, the astronauts planned to board a helicopter for the short flight to shore, then catch a plane directly to Houston for a reunion with their families.

Their capsule, Resilience, will return to Cape Canaveral for the refurbishment of SpaceX’s first private crew mission in September. The space station’s docking mechanism will be removed and a brand new dome-shaped window will be put in its place.

A tech billionaire bought the entire three-day flight, which will orbit 120 kilometers above the space station. He will fly with two competition winners and a physician assistant from St. Jude Children’s Research Hospital, his designated charity for the mission.

SpaceX’s next astronaut launch for NASA will follow in October.

NASA turned to private companies to maintain the space station, after the shuttle fleet withdrew in 2011.

SpaceX began deliveries in 2012 and last May launched its first crew, ending NASA’s dependence on Russia for the transport of astronauts.

Boeing is not expected to launch astronauts until early next year.

Elon Musk and SpaceX aim to launch SN15 Mars prototype rocket soon https://jenam2011.org/elon-musk-and-spacex-aim-to-launch-sn15-mars-prototype-rocket-soon/ https://jenam2011.org/elon-musk-and-spacex-aim-to-launch-sn15-mars-prototype-rocket-soon/#respond Fri, 30 Apr 2021 19:30:00 +0000 https://jenam2011.org/elon-musk-and-spacex-aim-to-launch-sn15-mars-prototype-rocket-soon/

SN10 takes off. SN15 has several upgrades over its predecessors.

SpaceX

After four successes test flights of SpaceX’s next-generation spacecraft prototypes it all ended with dramatic explosions during the landing phase, Elon’s Musk’s space company switched to SN15, a new version of its interplanetary rocket.

SpaceX has performed high-altitude test flights of the SN8 to SN11 prototypes and has long planned to incorporate what Musk called “major upgrades” into SN15. Now the company is skipping the SN12, SN13 and SN14, which were never fully assembled, and working on a flight of SN15.

Musk said SN15 “has hundreds of design improvements across structures, avionics / software, and engine,” including, hopefully, upgrades to cover some of the issues that have kept SpaceX from being successful. block the landing so far without a quick and unplanned disassembly.

SN15 has undergone some initial testing, and Musk originally tweeted that the goal was to launch last week, but that goal has continued to slide, and now a possible flight on Friday has also been cleaned up. On Thursday, the FAA said it had approved a launch license that covers SN15, SN16 and SN17, but currently it looks like we’ll have to wait until next week to see it fly.

SN15 can be launched anytime (or not at all) in approved windows once all required closings and permissions are in place. We usually have no clear idea of ​​when it will take off until less than an hour before takeoff looks set to happen (even then, false starts are common).

So for now, keep your fingers crossed to see SN15 fly (and land!). We’ll post a live stream of the launch here once it’s available.

SpaceX Starship SN15’s first test flight was cleaned up for Friday | Space https://jenam2011.org/spacex-starship-sn15s-first-test-flight-was-cleaned-up-for-friday-space/ https://jenam2011.org/spacex-starship-sn15s-first-test-flight-was-cleaned-up-for-friday-space/#respond Fri, 30 Apr 2021 18:50:36 +0000 https://jenam2011.org/spacex-starship-sn15s-first-test-flight-was-cleaned-up-for-friday-space/

The SN15 spacecraft prototype undergoes cryogenic testing earlier this month (April 2021) at SpaceX’s South Texas site. The SN15 has been equipped with many updates, in hopes of keeping it from exploding, as have 4 previous Starship prototype vehicles over the past 5 months. Image via SpaceX.

Update April 30, 2021: SpaceX did not perform the test flight of its Starship SN15 on Friday, April 30. The flight was cleaned up. The launch of the eagerly awaited test has been expected for several days. Bad weather conditions, including lightning, may have caused the scrub.

SpaceX develops Starship – what he calls a “fully reusable transport system designed to transport both crew and cargo to Earth orbit, to the Moon, to Mars and beyond” – and NASA chose this system as a lunar lander for its crewed Artemis program. Artemis is intended to transport the first man since the 1970s, and the first woman in history, to the moon of that decade. The final system will be paired with a giant SpaceX rocket thruster known as the Very heavy. SpaceX tested its latest prototype spacecraft this week at its South Texas site, Starbase. The prototype – SN15 (series n ° 15) – underwent its first static fire test on Monday April 26, 2021, and a second static fire test on Tuesday. During these tests, the craft remained on the ground while its three Raptor engines briefly ignited. But Starship is not designed to stay anchored on Earth. The big test is the high altitude test, in which it will rise about 10 km to the top. This test flight was sought after, especially towards the end of this week. But that hasn’t happened yet, and SpaceX hasn’t officially announced a launch date.

You may find an update on this forum, via NasaSpaceflight.com

SN15 will be the fifth Starship prototype to attempt this ascending flight in less than five months. The four before him – SN8 through SN11 – all flew well until the very end, when each exploded into a dramatic fire show. See the amazing video comparison at the end of this article. SN10 landed in one piece, but exploded on the airstrip about eight minutes later. SN11 launched about a month ago on March 30, reaching maximum altitude as planned, then exploding on landing due to a “plumbing problem,” said SpaceX founder and CEO Elon musk announced a week later. Essentially, there was too much methane in the combustion chamber, so the pressure was too high.

And so SN15 had a lot of “tweaks” hopefully to keep it from blowing up. SpaceX has built a reputation for persistence in failure, and it has the funds and resources to keep building prototypes and trying again. Starship and Super Heavy will be fully and quickly reusable, which could significantly reduce the cost of spaceflight, said Elon Musk.

SpaceX expects Starship to eventually succeed, and who could doubt that? They expect Starship and Super Heavy to be up and running soon. The oft-mentioned date for the final system to be fully operational is 2023. The Artemis program has a stated goal of getting humans back to the Moon – especially in the South Pole region of the Moon – by 2024, although many believe that this goal is not achievable.

According to Elon Musk, the reason SpaceX switched from SN11 to SN15 is that it was built at the same time as SN12, SN13, and SN14, but with major improvements. For this reason, SpaceX engineers decided to work with SN15 rather than finish building SN12 – SN14, which engineers already know are obsolete at this point. A similar scrapping is expected to occur with Starships SN18 and SN19. SN20 will likely have another round of major upgrades, and SpaceX currently has an ambitious goal of having SN20 fly into orbit with Super Heavy before July.

SN15’s first static fire came just three days after the launch of Crew-2, SpaceX’s second crewed operational mission to the International Space Station (ISS) for NASA. The Falcon 9 rocket carrying a Crew Dragon capsule lit up the pre-dawn sky above historic Platform 39A at NASA’s Kennedy Space Center in Florida, taking off at 5:49 a.m. EST (9:49 a.m. UTC; translate UTC to your time). It docked with the ISS in early April 24.

The videos below show the incredible handling and explosive fate of some of Starship’s previous test flights, over the past few months. The first video was posted by IssueKitchen on YouTube, who commented:

Elon Musk will never give up.

?

Conclusion: SpaceX conducted its second “static fire” test of the Starship SN15 on Tuesday, April 27, 2021, in preparation for its high altitude test flight, in which the vehicle will soar about 10 km uphill. The high altitude test, scheduled for Friday, April 30, was cleaned up probably due to bad weather and postponed to a future date as yet unknown.

The four-person crew spent approximately 23 hours orbiting Earth and catching up with the International Space Station after launch before docking at Node-2. Harmony module, marking the start of ESA’s six-month Alpha mission.

Thomas is the first European to be launched into space on an American spacecraft in more than a decade. The new Crew Dragon ships four astronauts at a time, allowing more people to live and work on the International Space Station by doing more research for scientists on Earth.

Alpha is Thomas’ second space mission, and everything should be bigger and brighter. A Russian lab module, due to arrive this summer with a European robotic arm, will provide more ways to maintain the International Space Station and support space walkers when working outdoors. Thomas will help set up this arm and prepare it for use during the Alpha mission.

More than 200 international experiments are planned during Thomas’ time in space. Of the 40 Europeans, 12 are new experiments carried out by the French space agency CNES.

At the end of the Alpha mission in October, Thomas will take over as Commander of the International Space Station for a brief period and welcome ESA Astronaut Matthias Maurer on his maiden flight into space.

SpaceX to resume Starlink flights, extending reused Falcon rockets to their limits – Spaceflight Now https://jenam2011.org/spacex-to-resume-starlink-flights-extending-reused-falcon-rockets-to-their-limits-spaceflight-now/ https://jenam2011.org/spacex-to-resume-starlink-flights-extending-reused-falcon-rockets-to-their-limits-spaceflight-now/#respond Tue, 27 Apr 2021 21:43:17 +0000 https://jenam2011.org/spacex-to-resume-starlink-flights-extending-reused-falcon-rockets-to-their-limits-spaceflight-now/

SpaceX aims to resume satellite launch for its Starlink Internet network with the launch of a Falcon 9 rocket on Wednesday night at Cape Canaveral, and company founder Elon Musk has said SpaceX will use up the massive backlog of Starlink missions. to keep pushing the limits and finding the Falcon booster. reuse the life limit.

“There doesn’t seem to be an obvious limit to the reusability of the vehicle,” Musk told Spaceflight Now at a press conference Friday after the launch of SpaceX’s third crewed flight to the International Space Station.

The launch on Friday of SpaceX’s Crew Dragon Endeavor spacecraft from NASA’s Kennedy Space Center marked the first time the company has sent astronauts into space on a reused Falcon 9 booster and refurbished crew capsule. NASA engineers have officially certified the first stage of the Falcon 9 previously used to transport astronauts, after more than 50 Falcon rocket flights have been successfully reused by SpaceX since 2017.

“You probably don’t want to be a leader for a crewed mission, but it’s probably good to have a flight or two under your belt, so that the booster has flown once or twice,” Musk said. “If this was a plane coming out of the factory, you’d want the plane to have probably had a test flight or two before you picked up any passengers.

“So I think that’s probably a couple of flights is a good number for a crew recall, and in the meantime we’ll continue to fly the leader of life,” Musk said. “We have nine flights on one of the boosters. We will soon have a 10th flight with a Starlink mission. “

After a brief pause in Starlink launches to focus on the Crew Dragon mission, SpaceX is set to send another 60 internet satellites into orbit with a late-night lift off Wednesday from space station 40. from Cape Canaveral. Wednesday night’s mission recall – tail number B1060 – has flown six times since last June.

The instant launch opportunity on Wednesday is set at 11:44 p.m. EDT (0344 GMT Thursday). Another Falcon 9 launch with the next batch of Starlink satellites is slated for next week from Kennedy Space Center station 39A.

With Wednesday’s launch, SpaceX will have delivered 1,505 Starlink satellites into space, including prototypes and failed spacecraft that fell out of orbit and burned in the atmosphere. Jonathan McDowell, astronomer and expert in monitoring space flight activities, says 1,374 Starlink satellites are currently in orbit, with the next 60 launches on Wednesday.

The Federal Communications Commission has cleared SpaceX to deploy some 12,000 Starlink satellites operating at Ku-band, Ka-band and V-band frequencies, and at a range of altitudes and inclinations in low earth orbit. The satellites are already transmitting broadband signals at low latency to users who have signed up for the Starlink beta test.

SpaceX officials have previously said that the most recent version of the Falcon 9 booster can perform 10 flights with only minor inspections and renovations between missions. With a redesign, Falcon 9 boosters could complete 100 missions, SpaceX said when the new Block 5 booster design debuted in 2018.

Musk said on Friday that SpaceX plans to continue reusing Falcon 9 boosters until they break, likely exceeding the 10-flight mark.

“We intend to fly the Falcon 9 booster until we see some kind of failure with the Starlink missions, obviously just to make it a life leader,” Musk said.

SpaceX has used its fleet of Falcon 9 boosters to launch Starlink missions at an average rate of more than twice a month so far this year. On some of these missions, SpaceX used reused first stages that set new records for their number of flights.

The most widely used Falcon 9 booster currently in SpaceX’s inventory has logged nine launches and landings, either ashore or on the company’s floating ocean drone, depending on mission requirements.

Last year, a SpaceX official said it cost less than $ 30 million to fly a Falcon 9 rocket with reused parts, such as the payload booster and fairing, the aero- shell-shaped structure that protects the payloads of sensitive satellites during rise in the atmosphere.

Although SpaceX has proven that it can safely reuse the first stages, payload fairings, and Dragon capsules, the Falcon 9 rocket’s top stage remains a single-use component. None of SpaceX’s competitors in the commercial launch industry have successfully revived an orbital-class thruster. Some companies, like Blue Origin and Rocket Lab, plan to eventually salvage and reuse their rocket boosters.

Repeating a mantra he has consistently repeated for decades, Musk said last week that rocket reuse is a “fundamental holy grail breakthrough” needed to revolutionize access to space.

“To make humanity a true space civilization, we need to have a fully and quickly reusable rocket,” Musk said in a Thursday webcast hosted by the X Prize Foundation. “We’ve made progress in that direction with Falcon 9, where the booster is reusable, and the Dragon spacecraft – the top part – is reusable. But the Falcon 9’s second stage and the Dragon’s unpressurized chest are not reusable.

“And I wouldn’t say the booster, spacecraft, and Falcon fairing, they’re not quickly reusable,” Musk said. “It takes a lot of effort, a lot less effort than the space shuttle.”

He said SpaceX’s renovation crews at Cape Canaveral can reduce the turnaround time between Falcon 9 booster flights to less than a month.

“But landing at sea, then having to bring it back, and then take a month or so to get it ready for launch, I wouldn’t call it quick by aircraft standards,” Musk said.

SpaceX’s next-generation Starship vehicle is designed to be fully and quickly reusable, further reducing launch costs, according to Musk.

The first stage thruster, known as the Super Heavy, will return to the ground within minutes of launch, similar to the profile launched by the Falcon 9 rocket. The Starship will propel itself into Earth orbit, and eventually to destinations in space. distant, then re-enter the atmosphere at the end of its mission for a rocket-assisted vertical landing.

The entire Starship rocket stack will be nearly 120 meters high, with 28 methane-fueled Raptor engines on the first stage and six more Raptor engines on the Starship’s upper stage.

NASA awarded SpaceX a $ 2.9 billion contract on April 16 to develop a derivative of the Starship vehicle to land upcoming astronauts on the Moon as part of the agency’s Artemis exploration program.

A NASA-owned Orion crew capsule launched above the space agency’s powerful Space Launch System rocket will transport astronauts between Earth and lunar orbit, where the crew will dock with the unoccupied spacecraft waiting for move towards the surface of the Moon.

As part of NASA’s flight plans, the Starship will launch astronauts back into space to meet the Orion capsule for their return to Earth.

Despite the use of onboard engines on NASA’s retired reusable space shuttles, each of NASA’s SLS rockets is designed for flight. NASA plans to refurbish and reuse Orion crew pods after splashing at sea.

But the lunar mission is only part of SpaceX’s ambition for the Starship program. The rocket could launch massive clusters of small satellites, such as Starlink spacecraft, gigantic space telescopes, and carry large numbers of people into space. SpaceX says it can deliver payloads in excess of 100 metric tons, or 220,000 pounds, or into low Earth orbit.

“With Starship, we’re hoping to reuse it all,” Musk said. “It’s a difficult problem for rockets, for sure. It took us, we’re like 19 years now. I think the Starship’s design can work. That’s right, it’s a difficult thing to resolve, and NASA’s support is greatly appreciated in that regard. I think it will work. I think it will work.

“I would say it’s only recently that I think full and rapid reuse can be accomplished,” Musk said. “I wasn’t sure for a long time, but I’m sure now.”

Update: NASA and SpaceX have decided to move the undocking and landing of Crew-1 from Friday April 30 and Saturday May 1, respectively, following a review of the forecast weather conditions in the overflow areas at off the coast of Florida. The teams will meet on Friday to determine a new start window.

After examining the weather conditions, NASA and SpaceX decided to push back the astronaut splash aboard the Dragon capsule until Saturday morning.

The teams are now aiming for a return to Earth at 11:36 a.m. on Saturday, May 1 in the Gulf of Mexico off the coast of Florida.
