                           B 

        Hello,Earth!Can you hear me?” That's the voice more than 400,000 people received recently. It was from Philae,a space vehicle that landed on a comet in 2014. However its transmissions(傳送信號) back home went silent since then.

        It took a long time for Philae to make its way across the solar system and reach comet 67P/C-G. The space vehicle got there aboard the Rosetra probe(探測器)，which has been circling around the comet since Philae separated from it in November,2014. 

    Philae' s job was to collect materials to. study the comet's composition. And for about two and a half days after landing,it did just that,sending the information back to scientists on Earth. But Philae s landing on the comet's icy surface had not been smooth. While touching down,it jumped up and ended up in the shadow of something like a huge rock. Philae runs on solar power,but there was no light in the place where it landed. In the end,it failed to work.

    However,as comet 67P/C-G moved closer to the sun,more sunlight reached the space vehicle,allowing it to power up and come back online. Philae then sent something to Rosetta,which passed on the information back to Earth.

      “We only received the information for about 85 seconds,but that’s enough to let us know it is alive and well,” says Stephan Ulamec,who works for the European Space Agency. “We hope to work out where it landed exactly on the 4-kilometer-wide comet. Now we plan to change how Rosetta moves so that Philae can keep on communicating and receiving instructions."
