I like the science that is being done on long term spaceflight, which will be necessary for long duration missions to the moon and Mars.

Elon has nailed it with his reusable rockets, and now Starship. And I would love to see humans living on Mars. But in my opinion, the biggest thing they are going to need is a large potable water source. Cutting ice blocks and melting them down will take too much time and effort to sustain more...

Two things, semi-unrelated. First: I notice that ground controllers do an awful lot to/with the ISS. One the one hand, I'm sure some of it is helpful and takes some workload off the astronauts. On the other hand, while I know the astronauts do a lot of things that robots cannot, it must make...

How did they recover the trunk? Did it float?

You nailed it. Red dwarfs are unstable and blast UV into space on a regular basis. Plus, most planets around red dwarfs are tidally locked, another kick in the pants for life.

LMAO! I think this is hilarious! Both the concept and people losing their minds over it. Look at the facts people. Space X is notorious for setting target dates that they don't make. So I wouldn't worry about this trip actually happening in 2023. If by some miracle it does happen, it's a...

"The public will doubtless be excited, too. But if the arrival catches folks off guard, there will probably be considerable fear, anxiety and confusion as well, said Sheri Klug Boonstra of Arizona State University's Mars Space Flight Facility." Like there was when we brought back moon samples...

"It's actually farther into the habitable zone than Earth; Earth itself is barely habitable," Really??? You're going to go with that? Then they show a diagram of the TOI system and 700d is just on the inside of the habitable zone. Unreal.

"Still, "if you look at Earth, it doesn't have that much water by mass — in fact, Earth is slightly underabundant in water," Madhusudhan said." Based on what? How have they determined that Earth is "underabundant" in water?

I was not impressed with the Starliner's first flight. A clock error is a stupid error to have. And the engine continued burning because of it? Then it couldn't dock with the ISS because it was low on fuel. How much fuel did it burn? This raises questions in my mine if Starliner can...
