Apophis 2029 Flyby: Orbit Change & ‘God of Chaos’ Asteroid
Here’s a breakdown of the key details from the provided text:
OSIRIS-REx Repurposed: NASA’s OSIRIS-REx spacecraft, recently returned from a mission to asteroid Bennu, is being reassigned to a new mission called OSIRIS-APEX.
New Target: Apophis: OSIRIS-APEX will now focus on asteroid apophis, studying it before, during, and after its close flyby of Earth. Specifically, it will map the surface, monitor its spin, and measure the effects of Earth’s gravity.
Seismic study: A major goal is to measure seismic vibrations inside Apophis, which would be a meaningful advancement as this has only been done on the Moon and Mars.
RAMSES Mission (ESA): The European Space agency is planning a mission called RAMSES (Rapid Apophis Mission for Space Safety) to also study Apophis. It would launch in 2028 and arrive in February 2029.
Combined Observation: Both OSIRIS-APEX and RAMSES will observe Apophis, providing a comprehensive study of the asteroid during its Earth flyby. Proximity: RAMSES will hover as close as 3 miles (5 km) from Apophis.
