It's easy to forget good old Ethernet is so amazing nowadays.
1 GbE is old school and 10 GbE is becoming routine. With 100 GbE and above starting to become more popular at the mainstream's high end.
From that distance it probably wouldn't spot Godzilla.
Those reasons should also make Mars a silly place to try to colonise?
High speed destructive winds, combined with vacuum like pressures.
Dust storms, but you need pressure suits.
Worst of both worlds.
What is the smallest Earth living organism Perseverance's instruments are able to notice? Bacteria? Tardigrade?
Has the private sector sent any spacecraft to Mercury, Venus, the Moon, Mars, Jupiter, Saturn, or Pluto? NASA has done all that. What about Voyager 1 and 2? What has the private sector done that can compare to that? When it comes to space exploration science no other entity can hold a candle to NASA.
Really? The private sector has done great things when paid to do so. What ever happened to x prizes? There's a lot of good science done at private universities.
An ethernet cable was used to let the rover talk to the sky crane. The rover's computer has a Virtex-5 FPGA that is does the digital heavy lifting for landing, and image processing.
I like the idea that all these off the shelf technologies are making "probes" cheaper, now that SpaceX is slashing launch costs. Seldom do you see a government agency doing better-faster-cheaper.
Now that the rover is down, it will almost certainly have a long productive life. Landing machines on Mars is one of the most difficult things Nasa does.
Mars has an awful atmosphere for landing things. It's thick enough that you can't ignore it. It's thin enough that you can't land with only a parachute, and aero-braking is problematic. I guess low gravity is all mars has going for it as far as landing.
Agree. NASA is capable of doing great things. Unfortunately, it is often hobbled by Congress and its pork barrel politics.
Yeah, I saw that too. I thought the ship was still thousands of meters from the surface. Really weird.
More advanced engineering than basic science.
What the rover does on Mars is the science part.
It really is. Theres a disconcerting fractal perspective all the way down. At 2:40, I thought it was about to descend into an area of glacial valleys, and then it starts blowing dust clouds across then.
Well done NASA. Who says the public sector can’t achieve? When it comes to basic science there is no substitute.
The capabilities and bandwidth to get that footage is nothing to laugh at either. Plus the rover runs linux (compared to the usual embedded OS vendors like VxWorks), which is a derivative of the JPL cubesat OS they open sourced a while back.
The helicopter they brought with them is apparently also controlled via Zigbee, the home automation low power wireless network protocol.
The landing is really amazing footage. I didn't expect we would get to see things so clearly and from several perspectives.
