Next Crew of astronauts heading to the space station, Mega Moon Rocket

The next crew of astronauts headed for the space station…

An upgrade to our Artemis I mega Moon rocket and spacecraft…

And celebrating our home planet… some of the stories to tell you: this week on POT!

NASA spacex Crew-4 Mission to the Space Station

On April 18, astronauts from our SpaceX Crew-4 mission arrived at our Kennedy Space Center to prepare for launch to the International Space Station. Kjell Lindgren, Bob Hines and Jessica Watkins of NASA, along with Samantha Cristoforetti of the European Space Agency (ESA) are excited about their scientific expedition to the station.

“We’ve been training for many, many months and we’re starting to… we’re seeing all those boxes being checked. And it’s very exciting now to have this box checked. We are here at the Kennedy Space Center, looking forward to our launch here in the very near future.”Kjell Lindgren, NASA astronaut

The mission is the fourth crew rotation flight to the station on a SpaceX Crew Dragon spacecraft as part of NASA’s Commercial Crew Program.

Options under review for the upcoming dress rehearsal of Artemis I Wet

NASA is reviewing schedules and options for conducting the next wet dress rehearsal of our Space Launch System or SLS rocket and Orion spacecraft at our Kennedy Space Center in Florida. The agency has decided to roll the Artemis I mega Moon rocket and spacecraft back to the Vehicle Assembly Building to replace a valve and repair a leak, while an outside supplier of nitrogen gas, used for the test, performs upgrades on their systems. You can follow NASA’s Artemis blog for updates on the status of the test at:

NASA celebrates Earth Day with live and online events

To celebrate Earth Day, we’re hosting a free public event at Union Station in Washington, DC. The 3-day event, which began on April 22, featured NASA science information, live demonstrations and other family-friendly activities. Along with this in-person event, we’re also hosting online Earth Day celebrations that kicked off with live events on April 22. Online activities will continue to be available on demand until May 2. This includes content that is also available in Spanish. . Learn more at

Grammy-winning artist Eddie Vedder made a special long-distance phone call to the International Space Station (ISS) in celebration of Earth Day. Orbiting more than 250 miles (402 kilometers) above Earth aboard the ISS, NASA astronauts Kayla Barron, Raja Chari, Thomas Marshburn and Mark Vande Hei, as well as ESA (European Space Agency) astronaut Matthias Maurer, have enjoyed a unique view of our planet. They share their thoughts on having a front row seat to the global effects of climate change, reflect on stewardship of our planet, as well as the remarkable ability of space to bring us all together in a shared humanity.

NASA X-59 Silent Aircraft with SuperSonic Technology

NASA’s X-59 Quiet SuperSonic Technology, or QueSST, aircraft is designed to fly faster than the speed of sound without producing a loud, disruptive sonic boom, typically heard on the ground below aircraft flying at such speeds. speeds. Instead, with the X-59, people on the ground will hear nothing more than a quiet sonic thump, if they hear anything at all. Credit: NASA/Joey Ponthieux

X-59 back in California after critical ground tests

Our quiet X-59 supersonic experimental aircraft is back at Lockheed Martin’s Skunk Works facility in Southern California after months of critical ground testing in Texas. The test was conducted to ensure that the aircraft could withstand the loads and stresses of supersonic flight. The X-59 will now undergo further testing and development as engineers continue to push toward its first demonstration flights in communities across the US beginning in 2024.

Two spacewalkers by Roscosmos

Cosmonauts complete spacewalk to install robotic arm

On April 18, Roscosmos cosmonauts Oleg Artemyev and Denis Matveev completed a 6-hour, 37-minute spacewalk outside the International Space Station. The pair installed and connected a control panel for the 37-foot-long European robotic arm mounted on the Nauka multipurpose laboratory module. This was the 249th spacewalk for space station assembly, maintenance, and upgrades.
