Congratulations To ESA

My twitter feed’s been exploding with tweets about the comet landing. Unfortunately, the harpoons apparently didn’t automatically deploy, so they don’t yet have a sure grab to the surface, which could make sampling operations difficult. The surface seems to be softer than expected. But they’re still working the problem.

This is good news for asteroid miners, though.

[Update a few minutes later]

OK, hearing that they managed to anchor with the ice screws, so maybe harpoons are redundant now.

The Asteroid Retrieval Mission

Lee Billings describes the ARM policy mess.

It’s a mission they came up with for an overpriced, non-existent and unnecessary rocket looking for a mission. And note this rationale:

She and other NASA officials note that the advanced propulsion required for ARM would be enabling technology for a broad range of future missions and that ARM would be a crucial test for many deep-space activities crucial for someday reaching Mars. And it would do all this while keeping astronauts sufficiently close to home so that if something goes wrong, they could attempt an emergency return to Earth.

Safety is the highest priority.
