Carnival of Space 607

The Carnival of Space 607 is up at Urban Astronomer.

Universe Today – Hayabusa2 Fires an Anti-Tank Warhead at Asteroid Ryugu.

The spacecraft had to break up the surface material by shooting it with “bullets” – 5 gram impactors made of tantalum metal that are fired from the spacecraft’s sampling horn at speeds of 300 m/s (670 mph).

On April 4th, the Hayabusa2 spacecraft sent its Small Carry-on Impactor (SCI) down to Ryugu’s surface and then detonated it to create a crater. The SCI is a 2.5 kg (5.5 lb) copper projectile. It was accelerated by a shaped charge containing 4.5 kg (~10 lbs) of plasticized HMX explosive.

Hayabusa2 will locate the crater and if it is safe they will gather material from the new crater.
