The seemingly random fabric patching on the parachute encodes a 10 bit message:

"Dare mighty things" and also the coordinates on Earth for the Jet Propulsion Laboratory.

Percy landing was a great achievement but the whole thing is dressed up in a fug of confusion as usual.
Well educated idiots at the bbc still couldn't comprehend that its not real time communication even after all these years
of mars missions.
Mission control monitoring and reading out decent speeds etc gives the impression they are in control of the critical events.
In reality if they fell off their chairs and pulled a power cord out the thing would have still landed the same.
So a big salute to the people that engineered the craft and designed all the automated systems that worked so well.

Why are you so angry?

Of course men (and women) will go to Mars. The only unknown factor is when.

Some choose to dream, others to be limited by their lack of imagination.

They spelled out JPL in morse code with Curiosity rovers wheel tread wherever it goes too. Proper geeky smile

i think if we ever develop technology to get to mars, we may as well go somewhere else like Europa or some other place, as Mars is actually pretty inhospitable for humans, IMHO far more safer to travel further in a "comfy and safe" space ship to get to a place thats easier on the humans to explore and even search for life than a barren dead planet of Mars...

I believe that's partially why Jeff Bezos is keener on huge, mile-wide space stations that rotate to create artificial gravity. Babylon 5 kinda vibes here. These are based on the writings of former Princeton University physicist Gerard K. O’Neill. Bezos was at Princeton when O’Neill was teaching there.

I'll probably end up being like the movie Elysium I suspect.

Mars - 6 to 7 months
Jupiter/Europa - 3 to 5 years

Maybe he's the toaster replacement? Somebody order one?

That descent video is properly, properly amazing. The whole thing is just fantastical. Can't imagine what it must be like, designing a thing like the skycrane, and actually seeing it work.

And they've made it work - twice.

I felt they'd got away with it on Curiosity. But I thought they were pushing it a bit using the technique again for Perseverance.

They need to speak to some oil rig divers. At least they rotate out after a couple of weeks.
Maybe get some people to spend 1 year working and living underwater. Less dangerous and you have a way out if you go barmy.
Too much star trek on the telly giving the impression its all like a cruise ship lol.
nobody born even this morning will live to see any pictures from a planet in another solar system.
Our best hope is the telescopes and robotic space probes.
Obviously musk can spent his money how he wants but its all a vanity project for giant egos.

Can't they just talk to the various astronauts and cosmonauts who have already spent long missions in space?

Valeri Polyakov has only been to space twice, but the first was on MIR for 8 months then the second for 14 months.

Gennady Padalka is the current record holder for human time in space at 879 days. He spent 38 hours of that on spacewalks.

People have lived in space for enough time to get to Mars and back already.

vanity projects aside - and please correct me if i am totally wrong here with my assumptions - i think we have to ask ourselves why we want to go there - the Moon is a prime example of that - Mars actually offers us nothing (IIRC) in terms of resources for Earth apart from planting a flag and spending billions on trying to keep a few people alive there for a while trying to grow trees in a plastic dome (or even spuds ;-) ) . is our intention is to colonise it ? i mean really? i doubt it would really help us long term - is the intention to explore "local" space to mine resource for us on Earth? then lets do that - is our intention to try and leave Earth and live on other planets? then is Mars the "best" candidate for that? just because its close? I suspect the future of us, is big rotating spaceships that go and explore the solar system and drop ship down to the planets ....
