The United States’ space exploration program is taking a critical step forward with a successful major technical review of the core stage of the Space Launch System (SLS), the rocket that will take astronauts farther into space than ever before. Continue reading
NASA’s Galaxy Evolution Explorer, or Galex, was placed in standby mode Feb. 7, 2012 as engineers prepare to end mission operations, nearly nine years after the telescope’s launch. The spacecraft is scheduled to be decommissioned — taken out of service — later this year. Continue reading
NASA’s solar-powered Juno spacecraft successfully refined its flight path Feb. 1 with the mission’s first trajectory correction maneuver. The maneuver is the first of a dozen planned rocket firings that, over the next five years, will keep Juno on course for its rendezvous with Jupiter. Continue reading
Scientists help define structure of exoplanets. Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. Continue reading
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. Continue reading
The moon may look lonely, but it is far from alone. Small asteroids too dim to detect seem to stray into Earth’s orbit quite frequently and stay for short periods of time. We may even be able to bring one of these moonlets back to Earth for study. Continue reading
Astronomers on Tuesday (Dec. 20) announced the discovery of the first two Earth-size alien planets – a historic find for sure, but the newfound worlds didn’t exactly receive historic names. The two alien planets are officially known as Kepler-20e and Kepler-20f, a nod to the instrument that detected them, NASA’s prolific Kepler space telescope. Continue reading
NASA’s Kepler mission has confirmed its first planet in the “habitable zone,” the region around a star where liquid water could exist on a planet’s surface. Kepler also has discovered more than 1,000 new planet candidates, nearly doubling its previously known count. Continue reading
NASA’s Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the “Late Heavy Bombardment,” which may have brought water and other life-forming ingredients to Earth. Continue reading
This month on the 12 and 13 the Perseids Meteor Shower will peak. It is one of the best meteor showers to observe because it can produce up to 60 meteors per hour at the peak. You may also be able to see some meteors any time from July 23 to August 22. Continue reading
