1. What happened On November 12 was an unnamed spacecraft made history by landing perfectly on its target. It was such an amazing achievement because it landed on a speeding comet that was 310 miles from earth. The path that Rosetta had to take to get close to the comet was they had to revolve around earth thrice and Mars once. The reason why They had to do that to get enough momentum to chase the comet. 2. What went wrong with Philae's landing was that they bounced up and down. The reason why it was a serious glitch because the spacecraft landed in a cliff. It lost contact with it ever since. 3. The most important experiment Philae conducted while it was still alive was when they got information. The scientist are eager to get their hands on the data because it can help them with our world. In 2016 NASA plans to launch a spacecraft to zip close to an asteroid.
