It’s down. Didn’t look like the propulsive landing worked, but it didn’t blow up, just hit hard.

I’ve only heard about the main chute and airbags .

I'm just glad that Biden didn't shoot it down to show China how tough he was this time. < /sarc>

NASA frowns on propulsive landing, starliner uses airbags and chutes only. SpaceX wanted and test flew Dragon as a fully propulsive landing no chutes at all but NASA was like not just no but hellno. SpaceX dropped a Dragon test mule from a helicopter let it hit terminal velocity on the thick lower air and then fired up it’s Super Dragos it landed just fine. You only need chutes to go from aerodynamic terminal velocity to about 3 meters per second with airbags. Without chutes the terminal velocity is about 200 meters per second so you need that much delta V in your engines plus some margins for gravity losses and if you want to hover then 9.8M/sec/per second of hover too. Not a small ask of stored rocket fuel in a small landing craft.
