Fly-by complete!
@NASA_Orion completed its closest fly-by of the Moon this morning, 81 miles above the lunar surface, traveling 5,102 mph. Before the fly-by, we conducted an outbound powered fly-by burn, increasing speed at a rate of more than 580 mph: blogs.nasa.gov/artemis

- I'm impressed by our #Artemis I team's dedication - their care for @NASA_SLS and @NASA_Orion is keeping us on track. Designing for this environment is challenging, and our design stood up to the test of the storm. We are pressing toward launch on Nov 16: go.nasa.gov/3hC0spN
- This is why we test. Overnight, we unexpectedly lost communication with @NASA_Orion while reconfiguring the link between the spacecraft and the Deep Space Network. We've since restored the link with an adjustment on the ground and are examining root cause. go.nasa.gov/3XswKDZ
- We polled GO today to send @NASA_Orion on a powered fly-by approximately 80 miles above the surface of the Moon! Tune in to coverage of the maneuver on Monday, Nov 21 at 7:15 AM ET on nasa.gov/live.
- #Artemis is more than going to the Moon. We’re learning to live & work on another world so we can explore more of the solar system, and we need your help. We’re extending the deadline to June 3 to get your feedback on @NASA’s draft Moon to Mars objectives: go.nasa.gov/3yRK7DM
- We’ve been incredibly efficient with our use of propellant on #Artemis I so far. As of Nov. 21, we've used a total of 3.7K lbs of propellant, 76 lbs less than expected. We have 2.1K lbs of margin available over what we planned for use, an increase of 201 lbs from expected values.
- We've left lunar orbit! @NASA_Orion fired its main engine today to exit distant retrograde orbit and set itself on a course for Earth. The burn is one of two maneuvers we'll make ahead of splashdown on Dec 11. Next up? Return powered fly by on Dec 5. go.nasa.gov/3XJ3s4h
- The imagery we continue to get out of @NASA_Orion's onboard cameras is outstanding. Downlinked the lunar fly-by photos yesterday, and they are incredible - a few of my favorites below. Visit flickr.com/nasa2explore to see the rest.
- Activities are going smoothly for #Artemis I. @NASA_Orion completed a planned trajectory correction burn today, and entered into the Moon's gravitational field. We'll conduct another trajectory correction burn tonight before performing the fly-by burn tomorrow morning.
- Today at 5PM ET, we're hosting a media briefing to preview upcoming #Artemis I operations. @NASA_Orion is preparing to enter the Moon’s orbit, and we'll perform a powered flyby approximately 80 miles over the surface of the Moon. Tune in at nasa.gov/live.
