Space and NASA playing ARMAGEDDON - DART Mission - [Live: 24.11.2021, 06:20 UTC]

NASA is launching the DART Mission (Double Asteroid Redirection Test) on a SpaceX Falcon 9.

NASA's DART Mission Will Move Mountains In Space

DART is an attempt at trying to deflect an asteroid by kolliding with it at a high velocity.

Target is Didymos B, a 160 m diameter asteroid, on the 2nd of October 2022.

The expectation is that the 500 kg impactor will crash with a velocity of 6,6 km/s into the asteroid and result in a velocity change of the asteroid of around 0,4 mm/s.

The mission is called Double Asteroid because Didymos B is orbiting the much larger asteroid Didymos A.

If the test was successful can be observed by a change of orbital period of Didymos B. Didymoon is currently orbiting every 12 hours. The change of period is expected to be around 10 minutes.

DART - The First Planetary Defense Mission

Observing the changing period around an asteroid is much easier than observing the change in period around the Sun. That is the reason why a double asteroid system is an ideal experimental setup, instead of a lone asteroid orbiting the sun.

Update on the DART Mission Testing Planetary Defense via Asteroid Deflection, July 10, 2021

The payload will launch from Vandenberg Space Force Base in California on a twice flown Falcon 9 rocket.

A secondary objective is to test new technologies that have not been to deep space yet:

  • new roll-out solar arrays (that have been installed on the ISS before)
  • new xenon thruster engine
  • new antenna
  • new asteroid camera
