The European Space Agency’s deep space probe Rosetta transmitted high-resolution images of anasteroid millions of miles from Earth. Rosetta caught up with the Steins Asteroid 1 Friday night in the asteroid belt between the orbits of Mars and Jupiter. Unfortunately, shortly before its closest flyby at five hundred miles, Rosetta’s narrow angle camera stopped working.
Officials at the ESA were not sure exactly what caused the camera to fail. According to the mission manager, a wide-angle camera was able to take pictures and send them to the space center, adding that the overall outlook for the data was good.
The Rosetta craft, launched in March, 2004, is now reportedly about 250 million miles from Earth. A roughly three-mile-diameter Steins Asteroid is being studied for keys that could help unlock some of the mysteries about the creation of the Solar System.
( “ I think it's a typical asteroid and asteroids 2 are very irregular bodies, and particularly the smaller ones, they are extremely irregular, and the amazing thing seems to be that there is still one body more or less, and because the craters 3 are very defined, some of them are very ,very defined, but maybe it's crushed, and I want to say, and there is , if you look at the sizes of the craters, then most of the interior of the asteroid may be crushed, we have to investigate this”)
According to the Associated Press, data from Rosetta’s working camera was being processed in Southern Germany, while further infrared 4 data collected by the probe was beinganalyzed in Rome.
“I think it whets 5 our appetite for the next things to come. It looks like we get really something out of that mission. It is a… I ‘m very pleased that it works so well.”
- Astronomers have yet to witness an asteroid impact with another planet.天文学家还没有目击过小行星撞击其它行星。
- It's very unlikely that an asteroid will crash into Earth but the danger exists.小行星撞地球的可能性很小，但这样的危险还是存在的。
- Asteroids,also known as "minor planets",are numerous in the outer space. 小行星，亦称为“小型行星”，在外太空中不计其数。
- Most stars probably have their quota of planets, meteorids, comets, and asteroids. 多数恒星也许还拥有若干行星、流星、彗星和小行星。
- Small meteorites have left impact craters all over the planet's surface. 这个行星的表面布满了小块陨石留下的撞击坑。 来自《简明英汉词典》
