Roughly the start of success from the livestream: https://youtu.be/p1KolyCqICI?t=2265 Video (of the video from Perseverance): https://twitter.com/NASA/status/1384099167832735748 (Better version from the livestream in child comment https://news.ycombinator.com/item?id=26861334 )

I hope that in a little while we get an actual video like we got when the whole thing was descending onto the ground. I am not expecting much from Ingenuity but I would be very disappointed if we didn’t see any video from Perseverance. I know doing video requires a lot of power, but I really feel it is justified for something like this. It would become a historic video.

If I recall correctly, Perserverence was recording images at roughly 7hz and will be sending them back over the coming days. I don't think they are compressed as video, since perseverance has pretty wimpy main computers and isn't running FFmpeg like they had for the descent videos, which came from a separate system.

It made me so sad seeing them cheering and clapping, but not getting up and hugging each other :( So much happiness without the ability to vent it. Such a historical moment.

Funny. When I watched that sequence, I was thinking the opposite. That the length of the clapping and cheering would be "too much" for me. I imagined myself being in that room. I probably would have beed very happy, smiling and showing a "thumbs up" sign or something. But I would not clap or cheer. And I certainly would not want to be hugged by some scientist next to me :) How do other engineers here on HN feel about…

There's no chance of me hugging the people I work with. None. Ever. I would only go for drinks with a few of them, but not often. Places vary, and in previous places I've had good drinking buddies, but hugging work people has never happened and never will. I'd hug the helicopter.

It's something that became pretty clear to me over the past year - if you don't get excited by this kind of physical contact you're probably a little different from others. That's OK. I not only don't celebrate that way, it'd make me uncomfortable even for a peer I like to hug me out of excitement. It's not what I want but it's what other people want and it seems to be the norm. You may end up learning that this may…

I don't think it's just cultural or anything for most people. Not just communication. I am usually not overly social at all, but I am now starting to crave other people's body warmth on a physical level. Feels like a headache... I can't enjoy anything anymore, because of it. The craving is there all the time, there is no substitute for the closeness I have not. I fantasize about pressing my body through an overcrowded club, collecting other people's sweat on me, friends screaming into my ears spitting all over my face. Sweat, sebum, saliva, warmth, smell, microbes, laughter, eye contact. It's not a sexual desire, it's something different completely drained, thirsty, essential for survival. I think back then, if my group abandoned me, I would just die of loneliness on the forest's mossy floor, no matter the circumstances.

I am gonna be really irresponsible, once I got my vaccine shot.

This was painful to watch. The team can fly a drone on mars but apparently are so stupid not to realize there is zero science behind them wearing masks. https://swprs.org/face-masks-evidence/

While I believe that masks do help reduce the spread of viruses, I'll play along that there is no science to back up that statement.

Humans do not only do things because they "make sense" / "scientifically proven", many times we just do it because its low effort and helps make other people feel comfortable.

Its like smiling when you see a stranger, or saying good morning to someone. There is no sense to it, you don't plan to stop and chat. However, it breeds a comfort (and eventually a distant camaraderie) because a greeting means a lot to them. Typically a greeting signals (sometimes falsely) a lack of malicious intent.

Given they are a team all sitting in the same room, even if one of them is more comfortable with masks on (logically or illogically), its just a kind thing to do for each other. Much like choosing to keep your cellphone off in a theatre, choosing not to smoke while in a group on non-smokers (outdoors or indoors), choosing to let everyone else exit an elevator before you, or choosing to respond to a comment you know is likely better left ignored :).

I wish you the best of luck in the future, and hope (masks or no masks - whatever strategy to help others you choose to use) you use some small amount of your time/effort to help make other people's lives a bit more comfortable.

People looked older then, IMO. They smoked, had neat haircuts, and wore shirts and ties to work.

Owned a home, had 3 kids and were looking forward to their 10 year high school reunions.

Ouch. Right in the feels. Americana nostalgia, landscape of broken dreams song plays in background, fluro lights flicker on and off in the abandoned mall, an empty parking lot, Twinkies wrapper tumbling in the wind, somewhere static from the last analog TV purrs then switches off forever... Ask not for whom the generational bell tolls...

Second that about looked older... Maybe it was the super8 video quality

It's cool. And surprising to me how young the team is. Contrast to the other videos I've seen of NASA "mission control" form the 60s etc. Something transformational for me seeing this group of super young people achieve so much. Inspiring and hopeful and more :)

At various points they show people joining remotely via video chat. Perhaps the people in the control room self selected based on covid risk?

From the series, explanations of life in 2020-2024

Kind of sad, but valid point. Future historians seeing people wearing masks might think those kids were in the situation room for some biological attack apocalypse

To be clear - I get it - I have had almost a hint of that sensation but I can see it clearly with all the people I work with - socialization will snap back hard and fast and people will go wild, good for them!

No hugging but the joy in the room was palpable — even with masks you could see people literally laughing out loud when the altimeter data came in.

Not that much as it will no doubt be hardware accelerated.

My point is that if you're spending electricity to generate heat, you can divert as much as you want to do calculations with no reduction in the amount of heat generated.

The problem I suspect is where the heat is going, heating up a logic board won’t do much to stop the motors freezing.
