After successfully completing nearly five months scrutinizing the giant asteroid Vesta at its lowest orbit altitude, NASA’s Dawn spacecraft will begin its final major science data-gathering phase at Vesta on June 15, at an average altitude of 680 kilometers above the surface. Continue reading
This week I recommend to follow @NiteSkyGirl for news from an amateur astronomer who still observes the night sky with her backyard telescopes. For more Twitter follow suggestions see our astronomy list @TheAstroBlog/astronomy Weekly Stumbles: NASA’s Spitzer Sees the Light … Continue reading
A newly unveiled company with some high-profile backers — including filmmaker James Cameron and Google co-founder Larry Page — is set to announce plans to mine near-Earth asteroids for resources such as precious metals and water. Continue reading
A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion years ago. The system consists of the star HIP 11952 and two planets, which have orbital periods of 290 and 7 days, respectively. 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 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
As the United States settles in for the long winter ahead in American space launch capabilities, after a summer that witnessed the end of the Shuttle program, two radically different visions for the future have emerged, put forward by two equally different entities. Continue reading
A Russian-built Soyuz space capsule landed safely back on Earth late Thursday (Sept. 15), returning an American astronaut and two cosmonauts home after more than five months in space. The Soyuz TMA-21 spacecraft touched down at about 9:59 a.m. Friday local time at their landing site on the steppes of Kazakhstan in central Asia. Continue reading
Honeycomb Carbon Crystals Possibly Detected in Space. NASA’s Spitzer Space Telescope has spotted the signature of flat carbon flakes, called graphene, in space. If confirmed, this would be the first-ever cosmic detection of the material – which is arranged like chicken wire in flat sheets that are one atom thick. Continue reading
There is renewed interest in air-breathing spaceplanes or reusable boosters. At the same time, remarkable launch cost reductions in more conventional boosters are imminent due to the efforts of SpaceX and other firms. Continue reading
