Measuring Stellar Gravity
2013-08-23 08:58:22

[ Watch The Video: Star Flickering Discovery ] John P. Millis, PhD for redOrbit.com - Your Universe Online A star’s gravitational strength is key in understanding and modeling other properties of a particular star, to say nothing of understanding the planets that orbit around it. But making accurate measurements of a star’s surface gravity is difficult, and measurements are often only good to within about a 50% estimation of the actual value, sometimes worse. Now, however,...

NASA Reveals New Images, Video Of Asteroid Redirect Mission
2013-08-23 07:30:04

[WATCH VIDEO: Asteroid Redirect Mission Concept Animation] Lee Rannals for redOrbit.com - Your Universe Online NASA has released a new animation along with new photos of the space agency's proposed asteroid redirect mission. The space agency said it is developing the first-ever mission to identify, approach, capture and redirect a small asteroid into a stable orbit in lunar vicinity. The part of this mission would be performed by an asteroid capture vehicle, while another part of the...

NASA will host a news teleconference at 2 p.m. EDT Thursday, Aug. 15, to discuss the status of the agency's Kepler Space Telescope. Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, the region around a star in which the surface temperature of an orbiting planet might be suitable for liquid water. Launched in 2009, Kepler has discovered planets and planet candidates with a wide range of sizes and orbital distances and helped scientists...

NASA Attempts 'Hail Mary' To Recover Kepler Space Telescope
2013-07-19 14:23:40

Lee Rannals for redOrbit.com - Your Universe Online NASA is launching a last-ditch "Hail Mary" attempt to try and bring its Kepler mission back to life. The US space agency said that over the next week, the Kepler team will attempt tests to explore recovery of the spacecraft's reaction wheels, which failed back in May. Kepler needs its reaction wheels to help stabilize it as it searches for exoplanets around distant stars. The team will be continuing its efforts to conduct tests on...

Donald K. Yeomans Receives Carl Sagan Medal For Public Communication

NASA's Jet Propulsion Laboratory For his work making the solar system's nomads of the night sky -- near-Earth objects, asteroids and comets -- tangible and compelling for millions of people, Donald K. Yeomans, the manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, has received the 2013 Carl Sagan Medal from the American Astronomical Society (AAS). The Sagan Medal recognizes a planetary scientist for excellence in public communication....

NASA Celebrates Mars Pathfinder Landing Anniversary
2013-07-05 08:38:42

Lee Rannals for redOrbit.com - Your Universe Online Independence Day not only marks the date on which America became a free nation, but also when NASA's Mars Pathfinder mission landed safely on Mars in 1997 allowing the US to stake its first claim on another planet. Mars Pathfinder was carrying Sojourner, which was the first US Martian rover. The Soviet Union launched its Mars 3 rover in 1971, but communication was lost about 20 seconds after landing. Sojourner was the first successful...

Insights Into Unusual Dwarf Star Provided By Kepler
2013-06-04 08:36:46

University of Delaware Astronomer John Gizis of the University of Delaware, working with data obtained by the Kepler mission, is studying a highly unusual dwarf star and its powerful flares that may hold clues to the likelihood of life on other planets as well as to the behavior of our Sun. Known as an L dwarf, this coolest type of star is about 53 light-years from Earth. Gizis, who discovered it two years ago using a ground-based  telescope, has now conducted additional research...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...
