ESA announces asteroid mission to Apophis
A cartoon showing Apophis’s path in 2029
The European Space Agency (ESA) today announced that is beginning work on an asteroid mission, dubbed Ramses, to the potentially dangerous asteroid Apophis when it makes its next close-fly of the Earth in 2029.
Ramses needs to launch in April 2028 to allow for an arrival at Apophis in February 2029, two months before the close approach. In order to meet this deadline, ESA requested permission to begin preparatory work on the mission as soon as possible using existing resources. This permission has been granted by the Space Safety programme board. The decision whether to commit to the mission in full will take place at ESA’s Ministerial Council Meeting in November 2025.
Using a suite of scientific instruments, the spacecraft will conduct a thorough before-and-after survey of the asteroid’s shape, surface, orbit, rotation and orientation. By analysing how Apophis changes during the flyby, scientists will learn a lot about the response of an asteroid to external forces as well as asteroid composition, interior structure, cohesion, mass, density, and porosity.
Based on the track record of European space projects, which appear to always proceed at a glacial pace with late problems that cause the missions to miss their launch window (with the launch of the Franklin Mars rover as the poster child), the project is getting started far too late to meet its launch date of April 2028. We shall see if Europe surprises us this time and gets the project off the ground as planned.
Right now the only confirmed mission to Apophis is OSIRIS-APEX, which was redirected to the asteroid after it delivered its samples from Bennu to Earth. Many others have been proposed, including a commercial mission, but none appear to be confirmed or under construction.

Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies.

The cartoon illustrates a close-fly of Apophis in 2029 that feels too close for comfort. The information collected by Ramsus would be very helpful in determining what kind of asteroid deflection tool to deploy, should it be deemed necessary. I don’t think the path of something like Adophis can be predicted perfectly. What if it gives off little jets of gas, for example?
If Rasmus can only get there two months before the close approach to Earth that will be too late. This mission by the ESA should somehow be fast-tracked on an emergency basis.
Allan: That cartoon is NOT to scale. Do not worry. Apophis is calculated to not come close for at least about 160 years, if that. The odds are much longer.
