NASA Talk - Mars Entry, Descent and Landing with Humans

The Space Technology and Exploration Directorate at NASA Langley Research Center presented a five-part lecture series on “The Future of America’s Space Exploration Program” on the campus of Christopher Newport University. Each 75-minute lecture took place at the Yoder Barn Theatre in Newport News, Virginia and explores the ins and outs of America’s vision for deep space exploration.

Lecture 1: Path to Mars and Asteroid Redirect Mission: The First Step
Lecture 2: The Next Human Spacecraft: Orion and the Launch Abort System
Lecture 3: Escaping Earth’s Gravity: Space Launch System
Lecture 4: Mars Entry, Descent and Landing with Humans
Lecture 5: Spacecraft, Habitats and Radiation Protection

I love the details on the stages and reasoning while touching down on Mars! I'm going to use this to hone my KSP Duna landers!

[gabrielcroft]

Let's hope we reach home in a new world, we are trying to make a galactic history here.thankyou NASA .

As a general questions should be limited to AFTER the lecture is concluded. Both the audience and speaker benefit by keeping the topics on track.

Jeff Herath is such a nice guy! Hope to see more of his presentations. Any plans for him to come back? Actually all the presenters have been awesome.

40 tons landed on Mars!!?!
Woohoo! That would be next level... :)

We need to figure out how to terraform it. I believe there is a way with our current understanding.

what about angled solar panels that vibrate occasionally to shake off dust?

I wondered if NASA has explored coming down in a large spiral to burn off speed. Also using very large wings for a spiral decent.

[kapa]

i love that talk (the video at 15.30 is unbearable tho xD)

[AngelLestat]

I guess the news for the spectators about when NASA plans to reach mars was not very welcome.
I wonder if somebody in NASA takes into account the fast change in technology (almost impossible to measure or predict it) due self learning machines. I guess is a very important issue or variable in our predictions, to take into account, because it will change any long term plan that NASA may have.
Also, if mars is so difficult in so many ways, why not to do the Havoc Mission first? Which is so much more easy to do in every aspect.

The details for a human transportation we must construct in a few years, this is fully posible. We need an human base round mars which can be situated in one of the mars moon, or we can go to mars directly from a moon base, although at the moment we dont have an launchsite in tha moon, we will have a new launch site in the moon with an magnet acceleration system, new technologies and new power systems. At the moment actually we can use transport cargos to transport materials and humans from earth to moon, and from moon to mars. I work in a new energy power system. We have the obligations for us and the new generations

Now if they could just make the Senate Launch System affordable...

[puzzlemagnet]

So far this technology looks like in baby stage, since a soft robot as presented here will be extremely hard to hold and get grip of things and manipulate them, with enough power. plus let alone the system needed to pull the air is very complex, currently in the scale 1 to 10 I will rate this at -10 compare to current rigid technology, maybe in 20 years we talking otherwise. Sadly Nasa seems to go in extremely slow steps.

Imagine sending 100 non professional astronauts on the Starship for months and expecting there not to be a mutiny, widespread psychiatric issues, health issues otherwise...
