Space - the final frontier (Misc.) II

[Bamaro]

There are many things that could happen to Earth to make it completely uninhabitable for humans. We either colonize the solar system or go extinct. But the Moon makes more sense as it has a far less significant gravity well. Actually, a large asteroid would make even more sense.

If we cant protect our own planet from ourselves should we be spreading to others?

Yes?

From tomorrow, SpaceX plans to launch 6 rockets in 6 days including Starship IFT-6 on next Monday (plus 5 Falcon 9s with 3 Starlink missions and 2 other deliveries in orbit). Godspeed!

This is kind of interesting.
Scientist Says NASA Lander May Have Accidentally Killed Life on Mars
The 1970s Viking 1 and Viking 2 missions to Mars were intended to test to see if life existed on Mars. They got a brief indication that life did exist, followed up by a confirmation that it did not.
Now a German scientist says, maybe there is life on Mars but the way we were testing for it actually killed it in the test sample by adding too much water.

That is a really deceptive headline. No, NASA did not wipe out life on Mars.

I suppose most are familiar with the Kessler Syndrome (so much stuff in orbit that stuff starts colliding with other stuff creating a cascade of debris fields that eventually make space unusable).
The European Space Agency will launch a platform to grad and "de-orbit" an old satellite.

NASA has explored ways to deal with space junk. It appears ground-based lasers might be the most cost-effective option.
Cost and Benefit Analysis of Mitigating, Tracking, and Remediating Orbital Debris
Interesting stuff.

Dr Gilbert Levine, the designer of the Labeled Release experiment, continued to claim until his death in 2021 that it detected traces of life on Mars.
