> o7 I never came across this emoticon, but with what you wrote, its meaning became clear immediately. It's perfect.
Same, I thought I was terminally online but I've never seen this before.

Due to blade damage, Mars Helicopter Ingenuity will not fly again

#113Damage to the blade tip is apparent in the shadow. But I would try one more flight just to see how it fares in such conditions, if it can be corrected in software etc.
They talked about why they don't think it will fly anymore in the media briefing:
- Ingenuity is balanced down to fractions of a gram, and any imbalance, especially at the speed that Ingenuity spins its rotor at, will cause the spacecraft to tear itself apart.
- Most of the lift comes from the last 25 - 30% of its lift capacity. They think they lost about 25% of the rotor blade, and even if somehow the other blades lost the exact same amount to be completely balanced, there's just not enough lift left.

#114I just interned at the NASA office (at Ames) that designed large chunks of and did a lot of flight planning / analysis for Ingenuity. It had some really awesome people behind it and its success inspired a number of new Mars rotorcraft missions (rotorcraft will be an integral part of Mars Sample Return). Flight is going to be a huge part of future solar system exploration efforts and Ingenuity paved the way. o7
Isn't Mars Sample Return pretty much dead at this point?
No. It's probably better to think of the multi-mission MSR "campaign" as being reformulated to be lower cost and complexity.

#115That was an amazing run. Well done Genny!

It's nearly a kilometer from the rover, should be fine. But I agree that it's better to leave it, download the remaining images and data from memory, maybe leave the software running as an experiment in non-rad-hardened computers on the surface, and eventually put it in a museum, than risk it crashing in spectacular fashion.
The tips of the rotors approach the speed of sound. Around Mach 0.95. I'm sure someone can do the math on the maximum debris field, but I think it'll be larger than you're thinking.
Agreed: Our earth-based intuition is probably pretty off when the atmosphere creates 1% as much friction as it does here.

You joke, but Russia did that with their moon rover.
In 1993, to Richard Garriott, for just $68,000: https://www.space.com/8073-privately-owned-soviet-moon-rover...
But technically Russia might not have owned title to it in the first place. Sounds almost like an NFT before NFTs existed:

Space lawyer, Joanne Irene Gabrynowicz (University of Mississippi) said:
without reading the papers or knowing how they were processed and by whom, she can't speak to the validity of the ownership of a space object purchased at auction.
"However, a contention that buying a space object that landed on the lunar surface from a sovereign nation gives rise to a property right to the territory under it is wrong"... said that States-Parties to the Outer Space Treaty of 1966 cannot acquire lunar territory by landing an object on the moon. "The USSR was and Russia is a party to the Outer Space Treaty. It did not acquire the territory under the object when it landed. One cannot sell what one does not own. Since USSR/Russia did not have a property right to the territory under the landed object, there was nothing to sell."

Here, let me help you with that... O7 /| Λ
That's ridiculous, nobody swims up a waterfall (but actually, thanks for the illustration... my dad was in the military but apparently long enough ago that I entirely missed this) Edit: oh! You used a capital O rather than a little one! That makes loads of difference... the "hand" placement in o7 is way over the forehead, while O7 (or is it 07? either way) is much closer to a proper salute! Perhaps the military cultu…
It's also the wrong hand.
But I think the little o looks more like a head in this case.
O7 just looks like a hex code or something.

Hasselblad liked to advertise that there were a couple free ones on the moon, you just had to pick them up. To save weight for more sample returns, the Apollo astronauts did the logical thing and kept the film, but chucked the cameras out on the moon.
They chucked a lot of stuff--anything intended for surface use went out the airlock. The cost per pound to bring something back from the moon was higher than the cost per pound of basically anything they brought.
Depends.
If the primary point was to put a man on the moon, the cost of bringing things back is basically free.
If on the other hand the primary mission was bringing back as many rocks as possible, then yes, the return would be very expensive.

#120How did the prop tip get damaged like that? Did it crash into something?
They mentioned during the media briefing that the terrain they were flying in were featureless, which is extremely challenging for it to determine where it's at, and thus it's possible that it misidentified some aspect of the terrain and caused this. Unfortunately because communication was lost when it landed, the flight data was lost, so we will never know for sure what happened.
