The coming of asteroid (99942) Apophis in April 2029 has sparked plenty of discussion both inside and outside the astronomical community. Despite original fears that it be pose a threat, Apophis will safely pass around 32,000 km away from Earth – though admittedly that is still closer than some geostationary communications satellites. That close approach offers a unique opportunity for those interested in asteroid science to take an up-close look at one of these relic of the early solar system, and various groups are planning to do just that. A new paper from Victor Hernandez Megia and his colleagues at the German Aerospace Center (DLR) suggests a new mission that could provide even further insight into the interior of Apophis – by returning part of it to Earth.
