At the heart of the telescope is an array of 42 camera sensors specifically designed to detect alien planets passing in. "Since the Kepler space mission began detecting new candidate exoplanets by the thousands using the transit technique, radial velocity teams have changed focus from discovering new planets to confirming Kepler detections and measuring their mass," they write.įollow Mike Wall on Twitter and Google+. A United Launch Alliance Delta II rocket launched Kepler on March 7, 2009. These scientists often use the radial velocity method, which picks up tiny gravitational wobbles that orbiting worlds induce in their parent stars.īut Kepler's success has spurred some of these researchers to change tacks temporarily, according to Bhattacharjee and Clery. But the proposed mission remains in a sort of limbo at the moment.Īll this talk about exoplanet space missions is not to discount, of course, the many finds that have been made from the ground.Ī number of research groups around the world have employed Earth-based instruments - the HARPS spectrograph, on a telescope in Chile, and the HIRES spectrograph, on Hawaii's Keck Telescope, are two examples - to spot exoplanets. The second of Keplers four reaction wheels devices that allow the observatory to maintain its position in space has failed, NASA officials announced Wednesday (May 15). ![]() If approved and funded, WFIRST could potentially launch in a decade or so. It ran out of fuel and was retired in late 2018. Kepler launched and began operations in 2009. But let’s have a look at how these two telescopes differ Kepler was launched in March 2009 and used a 1. See which new spacecraft are waiting for their chance to hunt for exoplanets. NASA’s Kepler planet-hunter a space observatory gathered the data. Kepler and TESS are both amazing space telescopes that have and will revolutionise our understanding of exoplanets. The telescope would not only hunt for exoplanets but also probe the mysteries of dark energy and galaxy evolution, among other phenomena. NASA's 4-year-old Kepler spacecraft isn't the only observatory searching for alien planets. National Research Council deemed WFIRST the top priority for the next decade of astronomical research. The 3.5-year timeline for the Kepler Mission was chosen since it would take at least 3 years for the Space Observatory to confirm that a candidate planet is indeed Earth-sized and in the habitable zone. But many researchers are hopeful that NASA will be able to build and launch a roughly $1.5 billion observatory called the Wide-Field Infrared Survey Telescope. The Kepler Mission was supposed to last for at least three and a half years. ![]() Buy Here (Image credit: Store)Īstronomers hope to then point NASA's powerful James Webb Space Telescope- an $8.8 billion instrument slated for launch in late 2018 - at the most promising of these newfound worlds, scanning their atmospheres for water vapor and gases that may have been produced by living organisms, such as oxygen, nitrous oxide and methane.Īdditions to the planet-hunting picture get a bit murky beyond 2017.
