There is this emotion, not sure it has a name, which I am sure many engineers know -- when you prepare your system for a long time and then send it into the real world and watch it work... You can feel it in this video, e.g when you see the crane fly away after accomplishing the mission. If we don't have a name for this emotion yet, I hope the japanese or the germans invent one. :)

Now these points of data make a beautiful line

And we’re out of beta, we’re releasing on time

This is incredible quality. What's the file size of the video and what path did the data take?

It got sent back via orbiters ranging from the ESA's Trace Gas orbiter, the Mars Reconnaissance Orbiter or Mars Odyssey. Through those they can get up to 2 megabits per second [0] back to earth but that depends a lot on the orbiter it's talking to at a given time. The TGO is doing a lot and is one of the early high speed relays for the data from Perseverance. [1] There's also direct links to and from Earth but they'r…

The more impressive part is that the sky crane shot pictures, video and data and had to download everything to the rover before it was cut loose. As soon as the rover wheels touched ground, the tether was cut and the lander flew away.

So far life on Mars was not really confirmed, right? I thought this is the main goal of this mission.

In case the other thread doesn't make the front page, they also added a microphone to this lander and managed to capture the sound of Mar's wind, which to me is almost more amazing: https://soundcloud.com/nasa/first-sounds-from-mars-filters-o...

I may be wrong, but I believe this goes back to a suggestion made decades ago by Carl Sagan. Despite being in the mission profile for a number of missions, it never made it (and turned on) until now.

"ready to begin seeking the signs of past life."

This is a brilliant engineering feat but I don't agree with the premise of that statement.

This is NASA's own mission statement: "The goal of the Mars Exploration Program is to explore Mars and to provide a continuous flow of scientific information and discovery through a carefully selected series of robotic orbiters, landers and mobile laboratories interconnected by a high-bandwidth Mars/Earth communications network."

I don't know why I'm surprised at the amount of footage and the quality, but I am. This is really setting a new bar for missions like this, similar to what SpaceX has done in recent years. Stuff like this has got to be huge for getting interest and excitement from the general public and especially kids.

agree! I remember seeing still pictures from mars from the viking missions taken in the 70's and although they are pretty good this latest video quality and clarity means NASA/JPL has come a long way. Just seeing that alien surface where no person has(yet) walked is absolutely amazing.

As incredible as this footage is, it's even more mindblowing to realize we've been doing this for 50 years now. We know how to land on mars. Time to do it with people.

I agree we should send people as soon as reasonable, but this system is deploying about 1 ton of payload, which isn't going to go very far in terms of life-support equipment (dried rations, maybe... air scrubbers? No.)

The issue with landing people on Mars is that you have to fly them back to Earth.

We have to be prepared to 'die on Mars'.
