DART Probe

[ysabetwordsmith]

NASA has finally gotten around to a concrete step toward the Umbrella: launching a satellite to crash into an asteroid with the intent of changing its orbit.  This is a great way to deflect Earth-threatening objects, if applied at long distance.  \o/

That is disturbing given how many people seem to consider fragmentation and/or nuclear explosion to be viable options.

It looks like deflection is the only good one, and that has to be done far away. We may not have that much warning. 0_o

Thankfully, NASA has already figured all this out, and that why DART was launched. John Q public and the various congress-critters are still catching up, and Hollywood has a lot to answer for, but the people actually defending the planet are on the ball.

Which is one of the reasons why Arecibo II will end up being built... it was the only deep space radio telescope that could also act as a deep space radar, and gave us a much wider window of detection.

That would be more reassuring if NASA had more money and decision-making power. Politicians tend to be stupid, and they're the ones setting agendas and budgets.

I hope so. We urgently need that.
