NASA’s Perseverance Mars rover
Discussion
Don't forget that they did this before - nine years ago. Perseverance is basically a modified version of Curiosity. It uses the same basic chassis and vehicle although the suite of scientific experiments carried on board is different.
So NASA has had practice with this type of descent and landing.
Corrected to get the lander name right.

Umm feels odd correcting you Eric but don’t you mean Curiosity? So NASA has had practice with this type of descent and landing.
Spirit and Opportunity were the little dinky solar powered ones from about 15 years ago?
I know its a completely different field but I work in the oilfield industry - we can spend multiple millions of dollars and several years designing/developing specialist equipment to essentially just drill and steer through the earth beneath us. Temperature, pressure, shock and vibration are extreme variables but we designs to tools to cope accordingly... however, things still go wrong.
Fortunately, we can just pull it back out of the hole and fix it or replace with another one, not quite the same when your equipment is on another plant
The achievement of sending a tonne of equipment to another plant and landing it safely is nothing short of amazing. Hats off to all that have worked on this, and all past projects.

That reaction when they found out where it landed seemed like they may have been off a bit.
Didn’t they say that it had the ability to pick its own landing site and adjust accordingly?Basically it'll avoid rough ground, cliffs, stuff like that.

Yes, I did. In my head I was typing Curiosity. Brains are strange things. I'll correct the original message.Spirit and Opportunity were the little dinky solar powered ones from about 15 years ago?
There was also the even dinkier Sojourner, which was carried by the Pathfinder lander in 1997.

So what really happens to the Sky Crane Eric?
I know this has been answered, but here's a video of the how the landing works. The sky crane bit is at about 3 minutes inI'm in awe they managed to pull it off flawlessly twice.
I must be getting old.

I was amazed at the size of the rover
3m long
2.7m wide
2.2 m high
1,025 kg
The size of family car
Yeah it’s fairly loaded, UAV on board, power source, all the instruments, it’s a bit of a step up from the earlier tinny rovers that were basically cameras and solar panels on wheels. I always quite liked the Curiosity was called the Mars Science Laboratory (MSL).3m long
2.7m wide
2.2 m high
1,025 kg
The size of family car
Seemed appropriate
