End is nigh for Rosetta: Spacecraft will meet its end by crashing into a comet

After launching 12 years ago and achieving its primary mission of reaching an orbit around Comet 67P/Churyumov–Gerasimenko, the aging Rosetta spacecraft will now die. On September 30, the European Space Agency says it will command Rosetta to crash into the comet it has been following since 2014.

Now at a distance of more than 850 million km from the Sun, Rosetta's two solar arrays cannot collect enough power to guarantee the spacecraft's heaters will keep it warm enough to survive. Instead of putting Rosetta into hibernation, which engineers believe is not survivable, Rosetta will follow its Philae lander to the surface of the comet.

The journey, at least, should prove fruitful. During the final hours of descent, Rosetta will attempt to capture some very-high-resolution images of the comet while collecting other data about 67P. Scientists hope communications with the spacecraft continue right up until the very end—when it crashes into the comet.
