so duas coisas acontecem a meteoritos, graças a "deus" são vaporizados ou esplodem bem alto ou chegam ao solo. o space shuttle tinha de fazer uma serie de curvas para chegar a salvo e todos vimos o que pode correr mal mesmo não sendo visivel eles chegam ao solo bem rapido. Vejam o video do que caiu na russia, francamente a mim parece lagardo por alguem que esta em cima fora do alinhamento

A explicação da NASA :lol:

In a blow to UFO enthusiasts, NASA has said that a mysterious bright flash that appeared in photos of Mars taken by the Curiosity rover on April 2 and 3 is probably not a signal from aliens.

Justin Maki, who is in charge of Curiosity's engineering cameras at NASA's Jet Propulsion Laboratory, says the bright spot is "either a well-placed flash of reflected sunlight, or light shining through a chink in Curiosity's camera housing," according to NBC News' Alan Boyle.

The bright spot appeared in two photos taken on two different days by Curiosity's right-hand navigation camera. The navigation camera is a stereo camera and the flash did not appear in photos taken by the left-hand camera.

In an email to NBC News, Maki said:

In the two right-eye images, the spot is in different locations of the image frame and, in both cases, at the ground surface level in front of a crater rim on the horizon. One possibility is that the light is the glint from a rock surface reflecting the sun. When these images were taken each day, the sun was in the same direction as the bright spot, west-northwest from the rover, and relatively low in the sky."

In other Mars news, the Red Planet will light up the night sky on Tuesday during a rare event when the sun, Earth, and Mars arrange in nearly a straight line, called the opposition of Mars.

Stream da Estação Espacial Internacional

http://www.ustream.tv/channel/live-iss-stream

Descrição:

Live video from the International Space Station includes internal views when the crew is on-duty and Earth views at other times. The video is accompanied by audio of conversations between the crew and Mission Control. This video is only available when the space station is in contact with the ground. During "loss of signal" periods, viewers will see a blue screen. Since the station orbits the Earth once every 90 minutes, it experiences a sunrise or a sunset about every 45 minutes. When the station is in darkness, external camera video may appear black, but can sometimes provide spectacular views of lightning or city lights below.
