04.16.13 - The hunt is on for methods to aim a spacecraft at an asteroid.
04.15.13 - An infrared sensor that could improve NASA's future detecting and tracking of asteroids and comets has passed a critical design test.
03.05.13 - Latest observations indicate comet 2013 A1 will pass within 186,000 miles (300,000 kilometers) of Mars on Oct. 19, 2014.
04.10.13 - NASA's FY2014 budget proposal includes a plan to robotically capture a small near-Earth asteroid and redirect it safely to a stable orbit in the Earth-moon system where astronauts can visit and explore it.
03.29.13 - The Swift satellite observed a comet that may become one of the most dazzling seen in decades when it rounds the sun later this year.
03.25.13 - NASA and international researchers have discovered Earth's moon has more in common than previously thought with asteroids in our solar system.
03.18.13 - Scientists capture radar images of asteroid 2013 ET.
03.07.13 - A beautiful comet with a bulky name is making an appearance this month for lucky sky-watchers in some parts of the world.
02.19.13 - An initial sequence of radar images of asteroid 2012 DA14 was obtained on the night of Feb. 15/16, 2013, by NASA's 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif.
02.15.13 - Preliminary information indicates that a meteor in Chelyabinsk, Russia, is not related to asteroid 2012 DA14, which is flying by Earth safely today.
02.14.13 - Asteroid 2012 DA14, set to make its closest approach to Earth on Feb. 15, is captured in early images from Australia.
02.13.13 - NASA Television will provide commentary starting at 11 a.m. PST (2 p.m. EST) on Friday, Feb. 15, during the close, but safe, flyby of a small near-Earth asteroid named 2012 DA14.
02.15.13 - Small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15. There is no chance that the asteroid might be on a collision course with Earth.
02.07.13 - According to NASA's Near Earth Object program, there are more than 1,300 potentially hazardous asteroids that have a very small chance of hitting us someday because their orbits come close to Earth's orbit. The main difficulty is obtaining sufficient observations to predict their orbits with enough certainty to find out if any of them might actually hit us at some point.
02.05.13 - NASA's Deep Impact spacecraft has acquired its first images of comet C/2012 S1 (ISON).
02.04.13 - NASA will hold a media teleconference at 11 a.m. PST (2 p.m. EST), on Thursday, Feb. 7, to discuss an asteroid, 150 feet (45 meters) in diameter, that will pass close, but safely, by Earth on Feb. 15.
02.01.13 - A small asteroid named 2012 DA14 will safely fly past Earth's outer ring of satellites on February 15.
01.10.13 - NASA scientists at the agency's Jet Propulsion Laboratory in Pasadena, Calif., effectively have ruled out the possibility the asteroid Aphophis will impact Earth during a close flyby in 2036.
01.09.13 - Scientists using the Herschel Space Observatory made new observations of asteroid Apophis as it approached Earth this past weekend.
01.03.13 - A new study of images from NASA's Dawn mission examines remarkable, dark-as-coal material that speckles the surface of the giant asteroid Vesta.
