NASA crashed successful project on the moon

The spacecraft Flo and last mission concludes in a spectacular crash on the lunar surface today.

The two American spacecraft Ebb and Flow (Flo and last year), will at. 11.28   do a controlled crash against the lunar surface. This probe will be a spectacular end to a mission that has lasted about a year.

The spacecraft will hit the lunar surface at a speed of about 6050 km / h.

Revealed moon's turbulent past

The two  have gone into orbit around the moon since January 2012 to measure the celestial bodies while the gravity field in great detail in a project named Grail (Gravity Recovery and Interior Laboratory).

- It is difficult to say having said Grails-leader Maria Zuber. Our tiny robotic twins has been exemplary member of the Grail family, planetærvitskap has made great progress thanks to their contributions.

Grails has given scientists the most detailed overview of the gravitational field of any planet in our solar system, including Earth, according to Zuber.

Among discovery made ​​with Grails is that the moon must have had a very turbulent past. Kjempemeteorar have shattered moon's surface to the porous gravel for billions of years ago when the solar system was in its infancy.

Not visible from Earth

In the first part of Flo and last mission flew sond about 55 kilometers above the lunar surface, and then go down to 23 kilometers altitude in the next part of the moon are staying. This height has been sond just a few kilometers above the moon's highest mountain.

Moon mission can not Extend more, because the probe is now nearly empty of fuel.

Since the twins to the seventh and last will crash on the surface anyway, just because of the moon's gravity, which probes studied, the Grails team rather take them down in a controlled manner.

How can they partly avoid the probe crashed into valuable historic landing place for Apollon-vessels.

From Earth, we see little of the spectacular crash.

- Flo and feathers are washing large spaceship with empty fuel tanks, so we expect not to see a flash of light that is visible from Earth, says Zuber.
