Space X

Three cheers for Elon Musk, launching a rocket, about 50 metres past the Goodyear Blimp.

And the docking footage looks comical

It has now well exceeded it's 36,000 km warranty.

Matt Damon grew his own potatoes there and survived.

Different thing altogether. Only the protection of the earth's magnetic field, makes the space station habitable, cosmic rays are an extreme hazard, even the moon astronauts were adversely affected by their brief exposure.

The exploration should be done by robots, catering to the fragility of humans in the non-Earth orbit field is impossibly costly. Carl Sagan said as much 40 years ago, it still holds true. Musk and his people on Mars in his lifetime, not going to happen.

I don't think you understand the difficulties imposed by cosmic rays, which are mass particles with tremendous kinetic energy, that are exceedingly difficult to shield against.

I reckon the whole space thing is just about trying to find a better world to live in, a bit like sci-fi stuff. Massive waste of money and time, but good for new creative ideas. God knows we need some, or we're stuck with an earth that'll be gone if we don't stop using deodorant etc.

One eighth of the iron in the asteroid belt is more than a million times greater that the estimated iron ore reserves on Earth.

Just back to the original moon conquest, was the Lunar takeoff leaving the moon, actually filmed from the moon?

Yep done that. 2 days off for covering other people's days, and reports all done. Good of you to appear out of space, SC.

Good job SC. If I was writing your report I'd say "she is developing her understanding" of...

I couldn't care less. Moron, whatever sex.
