Doesn’t science need to progress more before it’s economically viable?

We got to the moon 50 years ago and still haven’t been back. It’s expensive to send humans into space.

Let’s get those Tesla robots to Mars… and Titan

It's expensive to send anything into space, let alone make it to Mars. Chemical rockets are not cheap, even when you can recover the boosters and refurbish the engines. Comparatively, even visiting Mars makes a moon mission look like a cakewalk.

Let’s have that discussion about manned vs unmanned space flight again.

It’s been 11 years since HN thought manned was better.

Where’s the guy who told us crab fishing in Alaska is also dangerous?
