The Kepler telescope is down but not out. The observatory was NASA's preeminent planet-hunting machine until May, when a mechanical failure on the spacecraft cost Kepler its precise pointing ability and, with it, the power to discover small exoplanets that could be similar to Earth. But space telescopes—even banged-up ones—are hard to come by, so NASA put out a call for ideas on how to repurpose Kepler. In response, scientists suggested more than 40 new missions for the spacecraft. Some are modified ways to carry on the search for planets, whereas others represent new directions altogether. Here are four intriguing blueprints for Kepler's second life.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
