NASA has announced that the latest Kepler data dump contains 1,091 extrasolar planet candidates, with 196 Earth-sized planets among them. The data shows "a clear trend toward smaller planets at longer orbital periods is evident with each new catalog release. This suggests that Earth-size planets in the habitable zone are forthcoming if, indeed, such planets are abundant." Total Kepler candidates as of February 27, 2012: 2,321. [more inside]
Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.
NASA's Juno spacecraft launched this morning and is en route to Jupiter (launch video). Equipped with microwave, ultraviolet, infrared, and visible light detectors Juno will investigate the origins, atmosphere, and magnetosphere of the Solar System's largest planets over one year beginning with its arrival in 2016. Using its awesome solar-powered technology Juno will show Jupiter's magnetic field in detail never before seen. We probably won't hear much from Juno again until 2013, when it makes a fly-by of Earth. You can follow Juno on Twitter, so if it types out its scream, someone will hear it. Also
screaming traveling aboard Juno are three very special LEGO mini-figurines.
On February 14 NASA's Stardust-NExT mission revisited the comet Tempel 1. Tempel 1 was first visited by NASA's Deep Impact, which smashed into the comet back in July 2005. [more inside]
NASAs Kepler mission has discovered over 1,100 extrasolar planet candidates. Including, "68 Earth-sized, 288 super-Earth-sized, 662 Neptune-sized, and 165 Jupiter-sized planets". 54 are found in their star's habitable zone, with five of those considered "near-Earth sized" [more inside]
Challenger . . . . go with throttle up. Twenty-five years ago today the U.S. Space Shuttle Challenger exploded 73 seconds into the 25th space shuttle flight. The reports (pdf) tell us of O-Ring failures. Today, we remember one of the most tragic days in the history of the U.S. manned spaceflight program. Today, January 28, 2011, we remember: Michael Smith, Dick Scobee, Judith Resnik, Ronald McNair, Ellison Onizuka, Gregory Jarvis, and Christa McAuliffe.
Emily Lakdawalla has published the first 42 of 99 Voyager Mission Status Bulletins (thanks to space fan Tom Faber). Before the days of the internet, updates on space missions were distributed via newsletter. From 1977-1990 NASA published these Voyager newsletters to update scientists and enthusiasts. Both Voyager I and Voyager II are still out there, hurtling toward the stars. Voyager I and II weekly status updates from 1995-present are currently available online. Lakdawalla will be publishing the rest of the bulletins after she indexes them.
The Space Shuttle is still retiring but a U.S. Senate plan (full text PDF), (House version) would add one more flight to the shuttle's career, probably sometime late next summer. The move comes as thousands of jobs stand to be eliminated with the shuttle's retirement. [more inside]
Scientists at NASA will announce the first findings from the Kepler mission next month. The results have caught scientists off-guard but they aren't giving any hints as to what mission co-investigator David Latham "was not prescient enough to anticipate". [more inside]
