It took them approx. 4,881 hours from launch to land approx. 127,770,000 miles away. Is it safe to say that the average speed of the mission can be calculated as 436 miles/hour?

#52First surface photo is in too! https://i.imgur.com/C2s1job.jpg
The shadow features are fantastic!

#53NASA's ability of succeeding at landing things successfully on the first try on foreign bodies since 1969 is mind-blowing. Meanwhile, SpaceX takes half a dozen tries before managing to do the same on a fully known environment on Earth.
NASA also requires 10-100x more money & time to do so. Both just have very different ways of working. Both work and there are pro's and con's to either way!

#54I never forget a great fosdem talk regarding living on mars.

#55It's a great achievement with some really interesting work done on the landing algorithms with terrain recognition and it seemed to have worked exceptionally well.
Looking forward for the next landing in May of the Chinese rover and all the science these robots will produce. Also, the test of Ingenuity, the helicopter, will be very interesting to watch, that could really pave the way for a different exploration style in the future.
And finally, maybe the next transfer window will already see some Starships, that would really change everything.

How could you know? SpaceX never landed or sent a craft on a foreign body.

#57Seeing the engineers and scientists celebrating the successful landing was one the best things I've seen in a LONG while. Very live affirming and inspiring to me!

#58Any JPL/NASA HN users that could comment? That would be beyond awesome!
Great job, mission!

no. hohmann transfer, not a straight line. also there are no absolute reference frames.

#60I included this the other day in the previous Perseverance thread but if you're excited for the Perseverance EDL video hopefully Doug Ellison's composite video of Curiosity's landing (from a single camera) can tie folks over in the mean time! https://www.youtube.com/watch?v=RZioPhfxnSY
