NASA’s SpaceX Crew-3: Mission for Science | International Space Station
After more than six months aboard the International Space Station, the astronauts of NASA’s SpaceX Crew-3 mission are returning home. The four crew members—NASA astronauts Kayla Barron, Raja Chari, and Tom Marshburn, and ESA (European Space Agency) astronaut Matthias Maurer—are traveling back to Earth inside a SpaceX Crew Dragon spacecraft. These crew members contributed to hundreds of scientific investigations and technology demonstrations while aboard the orbiting laboratory. This valuable research helps to prepare humans for future space exploration missions while generating numerous innovations and benefits for humanity on Earth.
NASA's SpaceX Crew-3 Undock from International Space Station
The Crew Dragon spacecraft Endurance, carrying European Space Agency (ESA) astronaut Matthias Maurer and NASA astronauts Raja Chari, Thomas Marshburn and Kayla Barron, undocked from the International Space Station (ISS) on Thursday, May 5, 2022. The autonomous undocking marked the start of Crew-3’s return to Earth after almost six months in orbit.
Crew-3’s return will take approximately 23.5 hours. Their spacecraft will splash down off the coast of Florida in the United States, where ships will be waiting to bring it aboard and welcome the astronauts home.
This return also marks the end of Matthias’s first space mission, Cosmic Kiss. During his time on ISS, Matthias supported over 35 European and many more international experiments in microgravity. He also supported International Space Station operations and maintenance and performed a spacewalk with NASA astronaut Raja Chari on March 23, 2022.
After initial medical checks, Crew-3 crew members will be transported by helicopter to shore where a plane will be waiting to bring Matthias back to ESA’s European Astronaut Centre in Cologne, Germany, for his post-flight debriefings and rehabilitation.

NASA’s SpaceX Crew-3 mission launched Nov. 10, 2021 on a Falcon 9 rocket from the agency’s Kennedy Space Center in Florida and docked to the International Space Station Nov. 11, 2021.
Change of Command Ceremony | International Space Station
Aboard the International Space Station, NASA astronaut Tom Marshburn handed over command of the International Space Station to Roscosmos cosmonaut Oleg Artemyev during a change of command ceremony May 4, 2022. Farewell remarks also took place ahead of Crew-3 undocking and splashdown following their six-month mission aboard the orbital outpost. Marshburn and Artemyev are in the midst of long duration missions living and working aboard the microgravity laboratory to advance scientific knowledge and demonstrate new technologies for future human and robotic exploration missions. Artemyev, a veteran of three spaceflights to the space station, will lead the Expedition 67 crew until the end of summer.
Marshburn and his Crew-3 crewmates Kayla Barron, Raja Chari, and ESA astronaut Matthias Maurer have been living aboard the orbital lab since November 11, 2021, and are set to depart tonight. Hatch closure is set for 11:20 p.m. EDT, with undocking following at 1:05 a.m. EDT. The commercial crew quartet is due to splashdown off the coast of Florida at 12:43 a.m. EDT on Friday, May 6. Watch live on NASA TV, the agency’s website, and the app.
The Crew-3 astronauts worked on final Dragon cargo operations and configuring Dragon for departure, final egress, and hatch closure, as well as transferring emergency hardware from Dragon to the space station prior to departure. The Endurance crew closed out research operations which included transferring and packing frozen samples and ice bricks from the Minus Eighty (Degrees Celsius) Laboratory Freezer for ISS (MELFI) into coldbags in preparation for the return to Earth. MELFI provides the space station storage and fast-freezing of life science and biological samples. The Crew-3 astronauts also removed and stowed their Actiwatches, small, lightweight, wrist-worn devices that simultaneously detect body movement and light intensity. They are used to evaluate sleep-wake adaptation and circadian cycle and determine if space travel has an impact on the sleep-wake patterns of crewmembers.
The station’s four newest astronauts, Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti, had a light duty day performing some life science, lab maintenance, and inventory tasks. The foursome and their three Russian crewmates are due to have an off-duty day following the departure of the SpaceX Crew-3 mission.
Boeing CST-100 Starliner Spacecraft Rides to Atlas V Rocket | NASA Kennedy
NASA will soon have two spacecraft and rocket options to launch crews to the International Space Station.
Boeing’s CST-100 Starliner spacecraft passes by the iconic Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on May 4, 2022, making its way to the Space Launch Complex-41 Vertical Integration Facility at Cape Canaveral Space Force Station. At the pad, Starliner will be secured atop a United Launch Alliance (ULA) Atlas V rocket in preparation for Boeing’s second Orbital Flight Test (OFT-2) to the International Space Station for NASA’s Commercial Crew Program.
Set to launch May 19, Starliner will spend five to 10 days docked to the International Space Station before returning to land. The test is the last flight before the Starliner system launches American astronauts on the Crew Flight Test (CFT) to the microgravity laboratory—the spacecraft’s first flight test with crew on board. Potential launch windows for CFT are under review and will be determined after a safe and successful OFT-2.
Boeing's Starliner and SpaceX's Crew Dragon spacecraft have been developed and tested to fly astronauts to and from the International Space Station from U.S. soil.

Mission Minerva Meets Cosmic Kiss | Samantha & Matthias in Orbit
For the first time since mid 2011, the European Space Agency (ESA) has two astronauts living and working together aboard the International Space Station (ISS). Watch a conversation between Samantha Cristoforetti and Matthias Maurer in this rare moment for Europe in space.
The astronauts’ meeting marks a brief crossover between the start of Samantha’s second space mission, Minerva, and Matthias’s final days in orbit for his first mission, Cosmic Kiss.
Samantha arrived with Crew-4 on April 28, 2022, on SpaceX Crew Dragon Freedom, while Matthias will depart with Crew-3 in SpaceX Crew Dragon Endurance in May after almost six months on the International Space Station.
In this video Matthias is impressed by Samantha’s floating ability and says it is like she never left. Samantha confirms weightless was the thing she missed the most on Earth and talks about the differences on the Station since her Italian Space Agency ASI-sponsored Futura mission in 2014-15.
Matthias is pleased with what he has achieved in his time on ISS, including the science he has supported and the spacewalk he performed. He wishes Samantha all the best for her mission as she wishes him a safe return to Earth.
NASA's Artemis Program: Lockheed Martin's Vision for Lunar Mobility with GM
Only 5% of the Moon’s surface has been explored by the human race and to reach the other 95%, NASA astronauts on the Artemis program are going to need some serious wheels. This is why Lockheed Martin and General Motors have teamed up to design the next generation of lunar rovers, capable of transporting astronauts across farther distances on the lunar surface. Unlike the Apollo days when the rovers only traveled four miles from the landing site, Artemis astronauts will go farther and explore more of the Moon’s surface than ever before to conduct critical scientific research.
This type of mobility is a huge step—or a giant leap—toward enabling and sustaining long-term exploration of the lunar surface. The science that Artemis astronauts will conduct will help NASA better understand the fundamental planetary processes underlying our solar system, and will help us better understand and protect Earth.
Not only will these vehicles be well-equipped to go the distance, they will also be driver optional. Autonomous, self-driving systems would enable the vehicle to operate with or without humans onboard, and pave the way for future human missions, commercial payload services and enhanced scientific utility.
“These next-generation rover concepts will dramatically extend the exploration range of astronauts as they perform high-priority science investigation on the Moon that will ultimately impact humanity’s understanding of our place in the solar system,” said Rick Ambrose, executive vice president, Lockheed Martin Space.
A Lockheed Martin-GM rover would be able to preposition itself autonomously near a landing site prior to the astronauts’ arrival, and astronauts would have the ability to task the rover from the Human Landing System or the orbiting lunar Gateway to conduct science operations without a driver. This enables NASA to fit more science into a smaller amount of time, and allows us to uncover the critical information that the other 95% of the lunar surface may hold.
Zooming on the Moon
Driving on the Moon is not your average off-roading experience. The new lunar rover concept would be expertly outfitted to drive over rugged terrain in the dark and cold.
Unlike Earth and even Mars, days and nights on the Moon are just under 14 days long. The Lockheed Martin-GM rovers would be designed to survive and even operate in the two-week long night that sees temperatures of down to -280 degrees Fahrenheit, and day-time temperatures of 260 Fahrenheit.
“The biggest difference is, when you design for the Moon and for space applications, the force of gravity is different and has to be taken into account,” said Madhu Raghavan, Global Research & Development Group Manager at GM. “There are extreme temperature swings, and the radiation in space becomes a challenge in terms of systems design. You’re also operating in a vacuum and designing your systems to withstand the shock of the actual launch.”
The vehicles’ design would expertly mitigate these challenges. Lockheed Martin has built multiple deep space robotic spacecraft that have gone to the Moon, Mars, Jupiter, Venus, asteroids, comets and other destinations throughout the solar system.
“We’ve led missions to other planetary bodies for decades, building spacecraft that can survive the high radiation environment, cold temperatures, and yet be very light and very reliable,” said Kirk Shireman, vice president, Lunar Exploration Campaigns at Lockheed Martin. “This is what we specialize in, and we are more than capable of meeting and exceeding this challenge for NASA.”
A Dynamic Duo
With both brains and brawn, the Lockheed Martin-GM alliance brings together innovations from both companies to make transformative vehicles, drawing on strong legacies of engineering and performance from both companies.
“GM is a world leader in automobile manufacturing and technology, and Lockheed Martin is a world leader in spacecraft. The two companies joining forces to build a mobility system on the Moon just makes perfect sense.”
Lockheed Martin will lead the team by leveraging its legacy and history working with NASA.
“Our goal is to build a vehicle that is affordable, that exceeds our customer requirements, and to do it rapidly. Digital tools are how we achieve that,” Shireman said. “We’ve demonstrated already across programs and proposals the speed, affordability and reliability that digital tools enable, and we fully expect to leverage and expand on that experience with this program.”
GM brings to the table decades of experience designing for on and off-road environments, a strong focus on quality and human safety, and a shared mission.
“There’s a lot of synergy between our two companies—we complement each other well,” said Jeff Ryder, vice president, Growth & Strategy at GM Defense. “The lunar rover designs for extreme off-road environments have a lot of similarities with our tactical military vehicles on the GM Defense side. It’s great to work with a company like Lockheed Martin who has a shared mission of supporting the warfighter.”
GM brings to the table state-of-the-art battery-electric technologies and propulsion systems that are central to the company’s extensive electric vehicle strategy. Research from the development of battery and power systems for the lunar rover may ultimately spur advances on electric vehicles back on Earth, too.
“Because the operating conditions are so extreme in space, our work on this project will help us make safer and better batteries back on Earth,” Raghavan said. “The Moon and Mars are, of course, totally unstructured, unlined roads. Designing for that environment will ultimately just make our EV capabilities on Earth that much stronger.”
Enabling a Celestial Human Future
As it was during the Apollo era, every minute of the Artemis astronauts’ time on the lunar surface will be carefully planned in order to maximize the science value of having humans back on the lunar surface for the first time since 1972.
So, what is NASA hoping to uncover on the uncharted territory that remains of the Moon? The Moon is often referred to as the cornerstone of the solar system. Scientific investigations on the Artemis program will help NASA understand the risks and potential resources of the Moon’s South Pole, where they hope to establish the Artemis Base Camp concept by the end of the decade.
“The technology has evolved so much in the last 50 years, to the point where we can now use autonomy for these vehicles to aid in the astronauts’ missions,” Shireman said. “Autonomy will enable these rovers to carry tools and samples, and allows the crews to do more in the time they have there on the surface.”
To achieve our ultimate goal of utilizing the resources on the Moon to sustain a human presence, Shireman says we’ll need to have a reliable way of transporting those resources. This is the first major step in that direction.
“I’ve worked on many space programs in the past, but this isn’t just another space mission,” said Ryder. “It’s the return to, and permanent habitation of the Moon. It’s not just cool or interesting –it’s historical. It’s a major milestone in human activity in space.”
According to Raghavan, he’s seen a major influx of job applicants for open positions on his project team. “This is the stuff you dream about as a kid in science class,” he said. “People want to be part of this.”
Other scientific activities that surface mobility could enable include field geology, sample collection and return, and deployed experiments. These investigations are conducted in the hopes that they may increase our understanding of how the Moon formed and evolved, how it interacts with the Sun, and how water and other resources arrived at the Moon, and how they are transported and preserved.
These are all questions that, once answered, will help us sustain life on the Moon. The Lockheed Martin-GM team stands ready to autonomously chauffeur the astronauts to the dark regions of the Moon to advance our human future in space.
“I always think about alliances, and how you have to start with something real,” Ryder said. “As we go do this, it’ll likely lead to additional opportunities. It’s a great pathway going forward, and I’m sure there will be more opportunities for our two companies to come together to further human spaceflight.”
Expedition 67 Flight Engineers at Work | International Space Station
Kayla, Raja, Tom, and Matthias Arriving Back on Earth This Week
NASA and SpaceX managers continue to plan for the departure of four commercial crew astronauts aboard the International Space Station this week. A change of command is also on tap as the 11 orbital residents transition to a seven-member crew before the end of the week.
NASA astronauts Tom Marshburn, Raja Chari, and Kayla Barron, with European Space Agency (ESA) astronaut Matthias Maurer are nearing the end of their space research mission that began in November. The quartet will first see Marshburn hand over station command to Roscosmos Flight Engineer Oleg Artemyev who will lead Expedition 67 until late summer. The following day, the four astronauts will enter the SpaceX Dragon Endurance, undock from the Harmony module’s forward port, then splashdown off the coast of Florida about 24 hours later.
The four departing astronauts have been handing over their responsibilities to the station’s newest quartet that arrived on April 27 aboard the Dragon Freedom. NASA astronauts Kjell Lindgren, Bob Hines, and Jessica Watkins with Samantha Cristoforetti from ESA are in the first week of a four-and-a-half-month research mission on the orbiting lab.
Rocket Lab 'There And Back Again' Satellite Launch in New Zealand
On May 2, 2022, the “There And Back Again” mission Rocket Lab successfully launched its 26th Electron rocket mission, deploying 34 satellites to orbit from New Zealand's Mahia Peninsula. Rocket Lab has now deployed a total of 146 satellites to orbit with the Electron launch vehicle.
The “There And Back Again” mission also saw Rocket Lab complete a mid-air capture of the Electron booster with a helicopter for the first time. After launching to space, Electron’s first stage returned to Earth under a parachute. At 6,500 ft, Rocket Lab’s Sikorsky S-92 helicopter rendezvoused with the returning stage and used a hook on a long line to capture the parachute line. The mid-air capture is a major milestone in Rocket Lab’s pursuit to make Electron a reusable rocket to increase launch frequency and reduce launch costs for small satellites. After the catch, the helicopter pilot detected different load characteristics than previously experienced in testing and offloaded the stage for a successful splashdown. The stage is being loaded onto Rocket Lab’s recovery vessel for transport back to the Company’s production complex for analysis and assessment for re-flight as planned.
The mid-air capture comes after successful recovery operations from Rocket Lab’s 16th, 20th, and 22nd missions, which saw Electron’s first stage execute a controlled ocean splashdown before being returned to Rocket Lab’s production complex. Like those missions, a reaction control system re-oriented the first stage to an ideal angle for re-entry during the “There And Back Again” mission, enabling the stage to survive the incredible heat and pressure during its descent back to Earth. A drogue parachute was deployed to increase drag and to stabilize the first stage as it descended, before a large main parachute was deployed in the final kilometers of descent. “There And Back Again” is the first time a helicopter catch attempt was introduced to recovery operations and today’s mission will inform future helicopter captures.
“Bringing a rocket back from space and catching it with a helicopter is something of a supersonic ballet,” said Rocket Lab founder and CEO, Peter Beck. “A tremendous number of factors have to align and many systems have to work together flawlessly, so I am incredibly proud of the stellar efforts of our Recovery Team and all of our engineers who made this mission and our first catch a success. From here we’ll assess the stage and determine what changes we might want to make to the system and procedures for the next helicopter catch and eventual re-flight.”
The “There And Back Again” mission launched from Pad A at Rocket Lab’s Launch Complex 1 on New Zealand’s Mahia Peninsula at 10:49 am NZST, May 3,2022, deploying satellites for Alba Orbital, Astrix Astronautics, Aurora Propulsion Technologies, E-Space, Spaceflight, and Unseenlabs. The mission brings the total number of satellites launched by Rocket Lab to 146. Among the payloads deployed were satellites designed to monitor light pollution, demonstrate space junk removal technologies, improve power restraints in small satellites, validate technology for sustainable satellite systems that can avoid collisions with untrackable space objects, enable internet from space, and build upon a maritime surveillance constellation.
Rocket Lab’s next mission is scheduled in May 2022 with more details to be released in the coming days.

NASA Simulation Suggests Volcanoes Might Warm Climate, Destroy Ozone Layer
A new NASA climate simulation suggests that extremely large volcanic eruptions called “flood basalt eruptions” might significantly warm Earth’s climate and devastate the ozone layer that shields life from the Sun’s ultraviolet radiation.
The result contradicts previous studies indicating these volcanoes cool the climate. It also suggests that while extensive flood-basalt eruptions on Mars and Venus may have helped warm their climates, they could have doomed the long-term habitability of these worlds by contributing to water loss.

NASA's SpaceX Crew-4 Launch Week "Outtakes": More by Popular Demand!
Crew-4 mission astronauts Kjell Lindgren, Bob Hines, Jessica Watkins, and Samantha Cristoforetti of Italy, at Kennedy Space Center’s Neil A. Armstrong Operations and Checkout Building on April 26 and 27, 2022. A team of SpaceX suit technicians assisted the crew as they put on their custom-fitted spacesuits and checked the suits for leaks. The four astronauts launched aboard SpaceX’s Crew Dragon, powered by the company’s Falcon 9 rocket, to the International Space Station as part of NASA’s Commercial Crew Program on Wednesday, April 27, 2022, from Launch Complex 39A at Kennedy.
Gemini North, one half of the international Gemini Observatory, a Program of NSF’s NOIRLab, uses a laser beam traveling through Earth’s atmosphere to adjust its adaptive optics. Like many large research telescopes today, Gemini North uses adaptive optics—bending its mirrors to compensate for atmospheric turbulence or “seeing”, which can blur the images of distant objects like stars and galaxies.
The laser beam, seen here as a pink-orange stripe on the sky, travels into the upper atmosphere where it creates a bright spot of light that provides a reference point for the telescope to follow, and correct for, the atmospheric turbulence. This long-exposure photograph shows the laser tracking its target near the zenith, appearing to paint the sky with light. The stars appear as trails as they revolve around the north celestial pole during the long exposure.
