NASA has simply resurfaced mind-blowing footage of Orion smacking into Earth’s ambiance at 11 kilometers (6.8 miles) per second.
That is greater than 32 instances the speed of sound (!!)
The video was captured throughout NASA’s Artemis 1 mission last year, and it is some of the lovely issues we have seen all 12 months.
Simply feast your eyes on this:
One 12 months in the past right this moment, NASA’s Orion spacecraft reentered the ambiance after finishing a 1.4 million-mile, 25.5 day #Artemis I mission across the Moon. View the complete size video right here: https://t.co/0Rn7eRETua pic.twitter.com/gX95N8Kz5J

A one-minute clip of the re-entry was shared on X this week by NASA’s Orion Spacecraft account, with a hyperlink to the complete 25-minute version. The brief clip has since gone viral for an apparent cause – it’s freaking insane!
The uncrewed Artemis 1 mission headed to the Moon last November and served as NASA’s first take a look at of its large house launch system that can someday hopefully take people again to the Moon, and finally Mars.
Two fast issues as everyone seems to be asking the identical questions:
1) the chunks will not be the “ablative” warmth defend. It does not come off it chunks, extra of a steady burning. These bits I consider are the low emissivity tape that wrapped Orion
2) the sudden adjustments and plumes are…— Chris Combs (iterative design enjoyer) (@DrChrisCombs) December 12, 2023
It was additionally a chance to place the Orion spacecraft to the last word take a look at. {A partially} reusable spacecraft that is designed to be crewed by as much as 4 individuals.
Within the Artemis 1 mission, Orion was despatched empty into house for 25 days, together with six days in lunar orbit, earlier than it was boosted again to Earth – with 16 cameras on the spacecraft documenting the entire thing.
Upon its return, Orion smacked straight into Earth’s ambiance, flaming up and producing a plasma wake behind it because it ‘skipped’ like a stone throughout al ake.
As Chris Combs, an aerospace engineer on the College of Texas at San Antonio – a facility that works intently with NASA – explained over on X, you may see some flaring all through the footage, which is brought on by little bits of tape burning up, and in addition management thrusters firing.
“Two quick things as everyone is asking the same questions,” Combs wrote on X.
“1) the chunks are not the “ablative” heat shield. It doesn’t come off [in] chunks, more of a continuous burning. Those bits I believe are the low emissivity tape that wrapped Orion.
“2) the sudden adjustments and plumes are management thrusters firing.”
He also added that the clicking and thumping sounds are the valves to fire the control thrusters.
Orion eventually splashed down via parachute in the Pacific Ocean on 11 December 2022.
Orion was testing a new kind of re-entry process: a ‘skip‘, which is where the spacecraft bounces off the atmosphere, allowing NASA to more carefully control where the spacecraft splashes down, regardless of where it first hits the atmosphere.
“The skip entry will assist Orion land nearer to the coast of the USA, the place restoration crews can be ready to convey the spacecraft again to land,” said Chris Madsen, Orion guidance, navigation, and control subsystem manager back in April 2022.
In its first mission, Orion made it 434,500 kilometers (270,000 miles) away from Earth, further than any spacecraft designed to carry humans to date.

NASA will subsequent take a look at crew aboard Orion within the Artemis II mission, which is scheduled to launch in November 2024. We will not wait!
