A Close Encounter of the Cosmic Kind

Get ready, Earthlings! The colossal Apophis asteroid, dubbed the 'God of Chaos,' is on a collision course with curiosity as it prepares for a flyby on April 13, 2029. At a staggering width of 1,100 feet (340 meters), this near-Earth giant is causing quite a stir among scientific communities eager to study it during this unprecedented close encounter.

Meet the Missions Tracking Apophis

Three visionary missions are gearing up to capture Apophis up close! Leading the charge is Ramses, the 'Rapid Apophis Mission for Space Safety,' being orchestrated by the European Space Agency (ESA). This mission aims to unveil the secrets of Apophis, mapping its orbit, rotational dynamics, internal makeup, and surface transformations during its pass by Earth.

Countdown to Launch!

Scheduled for a spring 2028 liftoff, Ramses hinges on a crucial funding decision at the upcoming ESA Ministerial Council in Bremen, Germany, this November. If approved, this groundbreaking mission will launch alongside two cubesats designed to gather vital data, with one possibly landing on the asteroid equipped with a navigation camera, seismometer, and magnetometer.

Global Collaboration: A High-Tech Adventure

In a show of international unity, the Japan Aerospace Exploration Agency (JAXA) will contribute a thermal infrared camera and other devices for Ramses. But that’s not all! JAXA is also preparing its own mission, DESTINY+, which will now make a detour to Apophis before heading to its primary target, the asteroid 3200 Phaethon.

NASA Joins the Cosmic Hunt!

Not to be left out, NASA's OSIRIS-APEX mission—an offshoot of its Bennu sampling endeavor—is already en route to Apophis. Despite looming budget cuts threatening its future, the team is moving forward with plans to maximize the asteroid encounter. Fingers crossed that Congress approves extended funding!

A Cosmic Collaboration!

If all goes according to plan, these three missions will provide an unparalleled glimpse into Apophis and its celestial ballet with Earth. Mission teams are actively collaborating to optimize their observations, ensuring that they gather richer data than any of them could alone. As Michael Nolan, OSIRIS-APEX's deputy principal investigator, notes, “The spacecraft have different strengths...by coordinating our efforts, we can achieve so much more!”
