NASA astronaut and SpaceX Crew-4 pilot Bob Hines is pictured during a training session inside a mockup of the Crew Dragon vehicle at SpaceX Headquarters in Hawthorne, California A pair of news conferences on Thursday, March 31, at NASA’s Johnson Space Center in Houston will highlight the agency’s upcoming SpaceX Crew-4 mission to the International Space Station. The mission will be NASA’s latest crew rotation flight involving a U.S. commercial spacecraft carrying astronauts. The Crew-4 mission will carry NASA astronauts Kjell Lindgren, Hines, and Jessica Watkins, as well as ESA (European Space Agency) astronaut Samantha Cristoforetti. The Falcon 9 rocket bearing the Crew Dragon capsule is scheduled to launch in April from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. Image Credit: NASA…

Record-setting NASA astronaut Mark Vande Hei, left, and cosmonauts Anton Shkaplerov, center, and Pyotr Dubrov of Rosccosmos are seen inside their Soyuz MS-19 spacecraft after landing in a remote area near the town of Zhezkazgan, Kazakhstan, Wednesday, March 30, 2022. Vande Hei and Dubrov are returning to Earth after logging 355 days in space as members of Expeditions 64-66 aboard the International Space Station. For Vande Hei, his mission is the longest single spaceflight by a U.S. astronaut in history. Shkaplerov is returning after 176 days in space, serving as commander of Expedition 66.

NASA astronaut Mark Vande Hei arrived at the International Space Station on April 9, 2021, and will return home March 30, 2022, after spending 355 days in low-Earth orbit. This duration breaks the previous record, held by retired NASA astronaut Scott Kelly, by 15 days. Vande Hei will return in a Soyuz spacecraft as scheduled alongside cosmonauts Pyotr Dubrov and Anton Shkaplerov. While clocking the single longest spaceflight by a NASA astronaut, Vande Hei contributed to dozens of studies from the hundreds executed during his mission, including six science investigations supported by NASA’s Human Research Program, or HRP. In this image from March 2017, Vande Hei trained for a spacewalk at NASA’s Johnson Space Center in Houston.

This image from 2020 shows a flame that was one of many ignited as part of the Flame Design investigation inside of Combustion Integrated Rack (CIR) to investigate the amount of soot that is produced in different conditions. The yellow spots are soot clusters that glow yellow when hot. These clusters grow larger in microgravity than on Earth because the soot remains within the flame longer. The CIR was created and launched to the International Space Station in 2008. NASA continues to study the behavior of fire in space. Americans can feel safer in their homes now than decades ago thanks to studies and standards that have removed highly flammable materials in clothing, beds, and furniture. NASA relies on similar studies and standards to protect…

NASA astronaut Mark Vande Hei peers at the Earth below from inside the seven-windowed cupola, the International Space Station’s window to the world. Just outside the cupola is the Soyuz MS-19 crew ship docked to the Rassvet module. Vande Hei is slated to become the U.S. record holder for most time spent in space. He arrived on station on April 9, 2021, and is scheduled to depart on March 30, 2022.
