The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [ 4 ] [ 5 ] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [ 6 ]
The NASA spacecraft OSIRIS-APEX hovers over the surface of the near-Earth asteroid Apophis, using its thrusters to disturb the asteroid's surface to reveal what lies beneath, as shown in an ...
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, April 13, 2029.
Ramses, or Rapid Apophis Mission for Space Safety, is a proposed ESA mission to a near-Earth asteroid 99942 Apophis.If approved, it is expected to be launched in April 2028, to arrive at Apophis in February 2029, before its closest approach to Earth.
Here's what to know about Apophis and how space agencies hope to protect Earth from other asteroids like it. Apophis to make 2029 flyby to Earth Apophis is projected to pass within 20,000 miles of ...
A space rock the size of a cruise liner will closely pass Earth in April 2029. While the asteroid Apophis won’t hit Earth, two spacecraft may tag along.
“Close,” in the space world, is a relative term. At its nearest, Apophis will pass roughly 19,000 miles (31,000 kilometers) above Earth’s surface. That's about one-10th the distance to the moon.
OSIRIS-APEX will orbit Apophis for around 18 months in a regime similar to that at Bennu. The spacecraft will perform a maneuver, similar to sample collection at Bennu, by using its thrusters to disturb Apophis's surface, in order to expose and spectrally study the subsurface and the material beneath it.
