Lecture by Patrick MICHEL, astrophysicist and CNRS research director at the Observatoire de la Côte d'Azur
We're living in the golden age of space adventures to asteroids, with numerous missions underway or scheduled by space agencies from different continents. Among recent successes, NASA's DART mission successfully carried out the first asteroid deflection test in September 2022, and the Hera mission (ESA), to be launched in October 2024, will
verify the result of this impact and potentially validate the
technique used. The second success concerns NASA's OSIRIS-REx mission, which in September 203 brought back to Earth samples from the asteroid Bennu, twice the mass of the target.
The third success involves NASA's Lucy probe, which flew over the asteroid Dinkinesh in November 2023, revealing its shape and the presence of a small moon made up of two rocky lobes!
What are the challenges, uncertainties and surprises offered by
all these missions? What are the big questions they seek to answer, concerning both our origins and our protection? What other projects are on the drawing board, and will we be able to visit the Apophis asteroid, which will pass so close to the Earth on Friday April 13, 2029, without posing a risk, that more than 2 billion people will see its light with the naked eye from Western Europe and North Africa?
Two months ahead of the launch of the Hera probe from Cape Canaveral, we look back on these magnificent adventures with breathtaking images and films, and on the challenges ahead.
