Why is this story not getting more traction on Hacker News? It seems like the ultimate nerd dream

There was a ton of different submissions, so each one ended up with not so many votes.

There was Hayabusa some years ago.

As expected, DART was Dead on Arrival ;)

Now they have to pick up the pieces and see if they had an effect on the asteroids orbit.

still waiting for the pics/vids of the crash from far away.

From ATLAS (Hawaii). South Africa also got a video already

me too... there was a second craft that was supposed to observe and report back, wasn't there? I didn't see it talking to the deep space network afterwards.

Yes, an Italian cube sat called LICIACube.

It will start broadcasting its data a little before midnight Eastern, though it might be months before everything is transferred. Because it is a cube sat (only 14 kg) the transmitters are not very powerful so I believe the transmission rate is low.

In general, does anyone know what protocol they're using to transfer large amounts of data back to earth? I'm wondering especially about error detection and correction.

Seems like a veiled (but really not so veiled) demonstration of military power, no?

No, military is much more about quantity. Far space is actually very pacifistic in its nature, because it reveals that all the Earth wars and squabbles combined are no more than a tiny mouse squeak on a tiny speck of dust on cosmic scale.

In space terms, barely. Competing military assets may, in the future, attempt to evade each other, or fight with submunitions or energy. The navigation tech is just chalkboard math. In Earth terms, ICBMs and UAVs can strike anything anywhere with better accuracy.
