The recovery craft haven't even been constructed yet. It will consist of an orbiting return craft, a lander with a rocket and two fetch helicopters similar to Ingenuity

We can, should, will, and must blow up the moon.

I would guess a lot more.. But I dont know the specifics. But the debris would keep all other orbital launches grounded

Question: If all the current satellites were destroyed at once. What would that change tomorrow? Some things I can think of: -GPS/GNSS. -Weather measurements. -Sat TV / news. -Some comms.
I am just thinking that it wasn't that long ago that we didn't have any of that, and we still managed two world wars just fine.
Alternatives to these are: -Knowing where you are/someone else is. -terrestrial weather measurement. -Short wave radio.

When will these samples be brought back to Earth?
Do they have a spacecraft already on Mars to send them back or will they have to send something new to pick them up?
I watched The Martian at the weekend so sorry for the silly questions haha

The course of events leading up to this was so bizarre.
Morton Thiakol pretty much knew it was too cold.

who knows, but the specific nations isn't as important as the risk of it happening at all, on a large scale...

Planets around red dwarfs are less likely to be habitable. Red dwarfs are far more temperamental than Sun-like stars, flaring often which irradiates nearby planets (which need to be very close in to be in the habitable zone).

No chance look at what we accomplished via nuclear propulsion in the 50s and 60s. The tech and and tooling we have now, combined with the new space race I'll be shocked if a unmanned- spacecraft doesn't fly past voyager in the next 15.

My kids are bored after 30mins in the car. I won't be sailing them on a 6 year round trip to Neptune

Hey I'm the guy that approves this shit, I'm not at my desk right now so if you guys could just go ahead and get started that would be great.

The desire to detect near earth and potentially threatening objects has been a recurring theme in proposals for detection equipment, budgets and observation time for at least several decades. It might not be the headline reason, but it often makes the list. NASA has also built up an extensive library of such discussions over the years. I hope that makes you feel better.

An ad after every 5 seconds of footage? Trash site. Just the the article don’t bother

Reply to comment by Radioactiveglowup in NASA and DARPA to partner on nuclear thermal propulsion demonstration by returnofjuju
i love they start nuclear propulsion in space specially things like the dual NTP/NEP design they were posting a few days back because the best that NTP alone can do is twice as better than chemical and we need better than that
this post is about nuclear propulsion the rest of your comment smacks of acolites of the church of the fissiontology pushing propaganda created by fossil fuel to slow the adoption of clean energy and doesn't belong to this discussion

The path is probably recorded and the position they are dropped in that path

Won’t they be covered in dust? How do we find them later?

I remember reading about a fusion reactor variant, that, while not ouputting a net gain, might be used (while using up porpellant) to accelerate particles in a rocket engine (usable only in the vacuum of space)...and some well-funded startup already developing this?

I just love the type of thinking required to design this mission.
Get stuck in sand on a safari - no issue - get stuck in sand on Mars - two decades of planning between the smartest minds of many national space agencies.

no, nothing exciting like that. Whatever it was, it looked in orbit, just really fast :P hard to really gauge distance though isn't it.

Could call it something like Satellite Harm Amelioration and Reduction Campaign
^(Cannot think of a decent K so SHARC with frikkin lasers it is)
