Engineers are targeting 8 pm ET on Thursday, March 19, for rollout of Artemis II. NASA’s crawler-transporter 2 will carry the 11-million-pound stack at about 1 mph along the four-mile route from the Vehicle Assembly Building at @NASAKennedy to the launch pad.

UPDATE: This teleconference is now scheduled for Friday, March 20, at 5:30pm ET (2130 UTC).

Listen in on Thursday, March 19, for an update on our X-59 quiet supersonic aircraft and its upcoming test flights. Details: go.nasa.gov/4sf0bs3

Today's spacewalk is underway! Come watch with us as @Astro_ChrisW and @Astro_Jessica work outside the International @Space_Station.

LIVE: Tune in to watch @Astro_ChrisW and @Astro_Jessica go for a spacewalk! Our astronauts are scheduled to step outside the @Space_Station at about 8am ET (1200 UTC) and work for about six-and-a-half hours. twitter.com/i/broadcasts/1…

Due to quicker-than-expected completion of closeout activities, Artemis II rollout may now begin as soon as Thursday, March 19. A final decision will be made on Wednesday. More info: go.nasa.gov/419QL5d

Teams are now targeting no earlier than Friday, March 20, to roll Artemis II to the launchpad, maintaining the opportunity for an April 1 launch attempt. More info: go.nasa.gov/4utuo8B

Happy St. Patrick's Day! ☘️ Shock wave imaging is just one of the techniques NASA's SCHAMROQ project is using to help us prepare for future phases of our Quesst mission! For more info visit: go.nasa.gov/3PcW69o

Join us here on March 18 to watch @Astro_Jessica and @Astro_ChrisW go on a spacewalk! It'll be Williams' first and Meir's fourth. The duo will make preparations to install solar arrays.

#MeteorSighting: A very bright daylight fireball was observed by witnesses from the northeast U.S. and Canada this morning, March 17. An analysis of currently available data places first visibility of the meteor above Lake Erie. The fireball - caused by a small asteroid nearly 6 feet in diameter and weighing about 7 tons - moved southeast at 45,000 mph before fragmenting over Valley City. The fragments continued on to the south, producing meteorites in the vicinity of Medina County, Ohio. 🔗 go.nasa.gov/4bcMwMg Eyewitness accounts supplied by the American Meteor Society

When OSIRIS-REx reached the asteroid Bennu in 2018, scientists expected to find a smooth, beach-like surface. Instead, they encountered a jagged, rugged world. Samples of the asteroid, brought back to Earth in 2023, are helping untangle the mystery: go.nasa.gov/4cMGBPb

NASA’s Parker Solar Probe just did it again. ☀️ On March 11th, it completed its 27th close approach to the Sun, flying just 3.8 million miles from the solar surface at a blistering and record-matching 430,000 mph. New data drops March 18: go.nasa.gov/474BFBH

LIVE: We're giving a preview of our next two spacewalks, taking place outside the @Space_Station on March 18 and April 1. twitter.com/i/broadcasts/1…

A 2.5-second rocket flight that heralded decades of discovery in space! Today marks 100 years since the first successful test of a liquid-fueled rocket. Robert H. Goddard's achievement would have appeared unimpressive by most measures: His rocket flew just 41 feet in the air, landing in a nearby cabbage patch. Liquid-propelled rocketry has been the backbone of spaceflight ever since. 📷 by Esther Goddard on March 16, 1926 (Clark University Archive)

Tomorrow is #PiDay – and while we love a good pie, our favorite flavor of pi is of the math variety. 🥧➗ Celebrate with us by solving some of the same problems @NASA scientists and engineers face every day: go.nasa.gov/4lsbEBW

A busy week of preparation, progress, and historic achievements at @NASA. 🌕 Artemis II teams move closer to launch readiness 🛰️ Resupply spacecraft depart the ISS ☄️ DART confirmed to have changed an asteroid’s orbit Here’s the latest in your NASA Minute!

About eight minutes after Artemis II lifts off, the Orion spacecraft and the astronauts aboard will be in space. But what happens after that? Check out the Artemis II daily agenda to learn about the activities of the 10-day lunar mission: go.nasa.gov/3NBxpmr

Now on display at Air and Space: 🌌 James Webb Space Telescope Pathfinder, a full-scale engineering model used by @nasawebb for critical testing in development of the spacecraft ☀️ Parker Solar Probe full-scale model built primarily out of spare parts and back-ups from the spacecraft that has flown through the Sun’s corona

@airandspace @NASAWebb 👀 What a sight! Thanks for helping us share these groundbreaking missions with the world.

On March 16 at 2pm ET (1800 UTC), experts at @NASA_Johnson will be discussing two upcoming spacewalks outside the @Space_Station. Share your questions in the replies with #AskNASA. go.nasa.gov/4b4sQtW
