The European Space Agency and Japan’s Aerospace Exploration Agency are set to launch a joint mission called Ramses to study asteroid Apophis during its close flyby of Earth in 2029. This effort aims to gather key data on how gravity affects asteroids, boosting planetary defense strategies against potential future threats.
What Makes Apophis a Big Deal
Asteroid Apophis, about 375 meters wide, will pass Earth at around 32,000 kilometers on April 13, 2029. That distance is closer than many satellites orbit, making it a rare event that happens once every few thousand years.
Experts confirm no collision risk for at least the next century. Still, the flyby offers a unique chance to observe an asteroid up close without traveling far into space.
Billions of people might spot it with the naked eye from parts of Europe, Africa, and Asia. This visibility adds excitement to what could be a landmark moment in astronomy.
Details of the Ramses Mission
The Ramses mission, short for Rapid Apophis Mission for Space Safety, plans to launch in 2028 using Japan’s H3 rocket from Tanegashima Space Center. It will reach Apophis by February 2029, just before the Earth encounter.
Once there, the spacecraft will monitor changes in the asteroid’s shape, spin, and surface caused by Earth’s gravity. This data could reveal inner structures and help predict behaviors of similar space rocks.
Japan will provide solar arrays and infrared imaging tools, while Europe handles the main spacecraft design based on past missions like Hera.

Why This Matters for Planetary Defense
Close asteroid encounters like this push scientists to improve ways to protect Earth. The Ramses team wants to learn how gravity can alter an asteroid’s path or structure, which might aid in deflecting real threats.
Recent events, such as NASA’s DART mission that successfully hit an asteroid in 2022, show growing tools for defense. Apophis gives a natural test without human intervention.
Experts say understanding these events helps build better warning systems. For instance, if a similar asteroid posed a real risk, data from Ramses could guide response plans.
This joint project also strengthens global ties in space exploration, much like the International Space Station partnerships.
Global Interest and Related Efforts
NASA is repurposing its OSIRIS-APEX spacecraft to study Apophis after its flyby, adding more eyes on the event. Other groups, including startups, are exploring ways to capture images or even land small probes.
Public interest is high, with social media buzzing about the “God of Chaos” nickname for Apophis. Educational programs are already planning events to watch the 2029 pass.
Here are some key benefits of studying Apophis:
- Reveals how asteroids react to planetary gravity.
- Improves models for tracking near-Earth objects.
- Boosts international cooperation in space safety.
- Inspires new generations in science and engineering.
Challenges and Next Steps
Building Ramses on a tight timeline poses risks, as the launch must happen by 2028 to meet Apophis. Funding approvals are key, with Europe set to decide soon.
Engineers are reusing tech from previous missions to cut costs and speed up work. Despite hurdles, the team remains confident in delivering valuable science.
As 2029 nears, more missions might join, turning this into a major collaborative effort.
Looking Ahead to 2029
The Apophis flyby could mark a turning point in how we view space threats. With Ramses leading the way, we gain tools to safeguard our planet for years to come.
