A NASA spacecraft collided with a moon orbiting a near Earth asteroid Sept. 26 in a demonstration of a technology that could one day be used to protect the Earth from a hazardous object.
China has set its sights on near-Earth object 202 PN1 as the target for a combined asteroid deflection and observation test mission due to launch in 2026.
China will aim to change the trajectory of a potentially threatening asteroid with a kinetic impactor test as part of plans for a planetary defense system.
A study outlining priorities in planetary science for the next decade backs continued efforts to return samples from Mars while recommending NASA pursue missions to the planet Uranus and an icy moon of Saturn.
NASA has hailed an agreement with the Space Force to share information on near Earth object impacts as a key step forward in planetary defense, even as the agency defers work on a mission it says is critical to tracking such objects.
NASA is ready to launch its first mission devoted to planetary defense, a spacecraft that will collide with the moon of a small asteroid to test the ability to deflect it.
A proposal to replace the giant radio telescope at Arecibo Observatory in Puerto Rico with a new facility suggests it could be used for tracking space objects as well as for scientific research.
With the Arecibo radio telescope set to be decommissioned, NASA is beginning to consider options for future planetary radar capabilities, including potential cooperation with the U.S. Space Force.
NASA’s small but high-profile planetary defense program has overcome disruptions caused by the coronavirus pandemic to continue searching for potentially hazardous near Earth objects.
After years of study and failed proposals, NASA has decided to proceed with development of a space-based telescope to search for near-Earth asteroids.
Scientists used an appearance by the NASA administrator at a conference April 29 to press him to fund additional missions that support the agency’s work in discovering and characterizing near Earth objects.
A year and a half after ministers declined to fund one mission to an asteroid, the European Space Agency is working on a second such mission that could support planetary defense efforts.
