Orion: return to Earth for subjective through a video of … – Begeek.fr

At the beginning of this month of December 2014 that NASA sent into orbit the Orion capsule for its first trial run in space. A crucial task in many respects since in the long term, is to the capsule to become the first capsule to transport astronauts beyond Earth orbit since the Apollo missions. If all is for the best, the first manned flight to Mars could also be done with Orion.

After a journey of 100,000 miles into space at 5,800 miles above our heads, the Orion capsule was back in the atmosphere at 32,000 km / h diving offers us live NASA from inside the capsule.

The return Orion on Earth from the inside

Thanks to a video posted by NASA, it is possible to experience some of the sensations that would be experienced by astronauts during the return of the capsule on land, noise and vibrations less!

The video posted begins 10 minutes before the Orion capsule will finish his trip in the waters of the Pacific Ocean. At this level of the mission, it enters the atmosphere at its maximum speed, it shows the heat of drag due to friction of atmospheric gases with the heat shield of Orion. The colors change as the temperature increases.

2700 ° C upon entry into the atmosphere

This friction causes the temperature to 2700 ° C around the capsule while the heat shield, which was the subject of attention for this mission, should strive to maintain a constant temperature of 24 ° C in the latter. Performance knowing that he is only 4 inches thick, although its effectiveness has been proven many times since it is the same technology that was used on Apollo.

Once extinct flames, Video shows the second phase of the landing of deploying parachutes of the Orion capsule so that the latter arises quietly at the speed of 32 km / h on the surface of Pacific. Impressive images that will delight fans of the space will have to watch again and again to wait until the next Orion flight scheduled for 2018.
