content: Yes, and hopefully this one will be as successful too.Still, when a mission is so far away, if something fails, it may be unfixable.We may never (or at least not for a while) know what happened if something fails.Look at what happened to the Indian Vikram lunar lander not very long ago.https://www.nasa.gov/image-feature/goddard/2019/vikram-lander-foundWe're lucky that unlike the Moon, Mars hassomeatmosphere to use in slowing the descent.This video is pretty neat

content: Too many hours playing Kerbal Space Program has greatly increased my appreciation of watching the telemetry screens. You get a good feel for when the physics of a situation looks bad....

content: I loved the way the final jet-propulsion 'descender' module releases the final payload!!It then takes off vertically, (less weight), but to where ??

content: Great technology. Superb engineering. But it is highly improbable they will find any evidence of alien lifeforms from the past. As for trying to create an environment that will support human habitation, there is no Planet B. Planet A is slowly being destroyed by a parasite. Hopefully good management, good education, and cohesive government can control the parasite so Planet A can become healthy again.

content: We're not parasites, we're just an adolescent race thats going though its difficult years, and hopefully we survive them in one piece and go on to our maturity and the stars.Maybe this will cheer us all up.While surfing the Magic Lantern web site (https://www.magiclantern.fm/) a few days ago, I came across this real gem of a short video which was one of the winners of a video contest NASA held a few years ago to explain project MARS). It was so good it made me cry like a baby. Now this is a perfect blending of art and science.https://www.magiclantern.fm/forum/index.php?topic=24858.0Alsohttp://vimeo.com/mariuskrivicius
