A powerful transmitter in remote Alaska sent long wavelength radio signals into space Tuesday with the purpose of bouncing them off an asteroid to learn about its interior. Data analysis is expected to take several weeks. UAFHAARP NASA JPL gi.alaska.edu/news/nasa-and-…

I am so excited to be part of the team planning this spacewalk! Koichi Wakata 若田光一 and Nicole Mann have worked hard for this. Tune in Friday for the culmination of a year of planning and training!

How do we practice on Earth to walk on the Moon? Check it out!

Lessons not to be forgotten waynehale.wordpress.com/2023/01/14/les…

Hello from New Mexico! 👋 Before we go to the Moon with #Artemis, we practice on Earth. The RISE2 team has spent the past week simulating lunar surface EVAs (extravehicular activities) in Potrillo Volcanic Field. We’ll post notes from the field over the next few days. Stay tuned!

“Ash hail”, or lapilli? How do volcanoes work? It all depends on who you ask.  Moonwalks require crew members with different professional backgrounds to share a common language for describing the lunar terrain, so our week of field testing began with a crash course in geology.

#DYK Earth is the only world with GPS? 🤔 There is no mapping app on the Moon. #Artemis astronauts, working with mission control, will use printed maps and nearby landscape features to estimate the crew’s position on the lunar surface.

Dreams are worth working and waiting for…April 1990, went to Space Academy. Came home, built Discovery. Studied, worked, taught high school. April 2010 launched on Discovery SpaceCampUSA SpaceCampAlumni NASA NASA's Johnson Space Center Challenger Center #STEM #STEMeducation

It takes hard work and dedication to a dream, but on days like this my 💙 is happy! Feeling very fortunate to be part of the incredible team NASA's Johnson Space Center preparing ARCHIVED NASA Astronauts for International Space Station and NASA Artemis!

At Potrillo Volcanic Field, the RISE2 team tests science tools for future moonwalkers. Ground Penetrating Radar (shown here) detects landscape layers buried in ancient ash. Above ground, thermal imaging and 3D laser scans of the terrain reveal clues hidden in plain sight.

A special day in the Mission Control Center: the “plaque hanging” honors our teammates who made exceptional contributions to an International Space Station mission!

Embracing the “international” part of our International Space Station operations this week, learning to fly the Canadian Space Agency Space Station Remote Manipulator System - aka Canadarm 2 - with our wonderful colleagues in Montreal.

33 years later, Hubble continues to explore and inspire! Hubble was deployed by Space Shuttle Discovery #OTD in 1990, becoming one of the notable success stories in NASA's history! Read about HST's early days in Chris Gainor's historical account: go.nasa.gov/3ovH3dq

Canadarm, meet Canadarm2 🤝 #OTD in 2001, the International Space Station's newly installed Canadarm2 transferred its launch cradle to Space Shuttle Endeavour's Canadarm, performing a "handshake" in space. Canadian Space Agency astronaut Chris Hadfield was at the STS-100 shuttle's Canadarm controls.

It’s been an awesome week learning to fly the Canadian Space Agency Canadarm2! Kristen Facciol and the ROBO team are rock stars. Thanks for making us welcome and providing fantastic training!

46 years. 12 billion miles. ARCHIVED - NASA Voyager 2 still sending back data on the far-flung edges of our solar system! It’s amazing what humans can accomplish.

When Andreas Mogensen goes to the International Space Station for his #Huginn mission, he will start as part of Expedition 69 and become the commander of the ISS during Expedition 70👨‍🚀 This is the first Expedition patch to be designed by European Space Agency 🥇🙌 #Exp70 esa.int/ESA_Multimedia…
