Moon science? Yes. Preparing for our long-term future in space? Also yes. ✅ ✅ The Artemis II lunar flyby mission will give humanity a new perspective on the Moon, and test the systems and technology that will eventually bring astronauts to the lunar surface to stay.

The NASA Artemis II mission will use Goddard's Near Space Network during launch, early orbit, re-entry, and splashdown! Learn more about how NASA's two networks work in tandem. go.nasa.gov/4a0Pgu9

Our "wet dress rehearsal" for Artemis II is underway at NASA's Kennedy Space Center! Watch our static feed as teams practice fueling the rocket and conduct a simulated launch countdown as we prepare for the real thing: youtu.be/5zDlM8d4Q7g Real-time Artemis updates: nasa.gov/blogs/artemis

Last week was anything but relaxing for the Artemis II crew! While in the astronaut quarantine facility at NASA's Johnson Space Center, the crew was working in the Orion simulator, completing medical checks, and finishing procedure preparations.

Wet dress rehearsal activities for the Artemis II countdown continue into today. Teams have been troubleshooting issues with filling the core stage with liquid hydrogen. The rocket is in a safe configuration. Get real-time updates here: nasa.gov/blogs/artemis

NASA completed a wet dress rehearsal for the Artemis II mission in the early morning hours on Feb. 3. To allow teams to review data and conduct a second wet dress rehearsal, NASA will now target March as the the earliest possible launch opportunity for the Artemis II mission.

Engineers conducted a first run at terminal countdown operations during the test, however, the countdown stopped at 5 minutes left due to a spike in the liquid hydrogen leak rate. Crew safety remains the highest priority.

Future missions will reach farther, stay longer, and take on more ambitious goals. NASA is partnering with U.S. Department of Energy to develop nuclear surface power and propulsion to support that future, and help propel a new Golden Age of Exploration.

Did you know... ...that the NASA Artemis II Moon rocket is 322 feet tall? That’s just a few yards shy of the length of a football field. Bet you thought we were going to say something else about #SBLX. 😉

International Space Station NASA Artemis On that note: If the International Space Station touched down on the #SBLX football field tonight, you’d see they’re very nearly the same size! The orbiting lab is 357 feet end-to-end – almost the same size as a football field, including both end zones.

Last week's wet dress rehearsal test for the Artemis II mission brought teams one step closer to liftoff. Since the test, technicians have replaced two seals in the area where operators found a hydrogen leak.

Teams also are adding additional time in the countdown to allow for more troubleshooting. March is the next potential launch opportunity. NASA will set a targeted launch date after completing a successful wet dress rehearsal test and reviewing the data. go.nasa.gov/4bFsDy0

During Artemis II, our crew will get the chance to study the Moon's surface up close—and NASA scientists will track how the human body responds to deep space travel. Explore the science of Artemis II in our latest episode of Curious Universe: bit.ly/498S0qf

You might know Orion’s Belt, but can you spot the full constellation – Orion the Hunter? Look for a line of three stars in the southeastern sky (the “belt”). From there, surrounding stars make up Orion’s shoulder, sword, head, and shield.
