There’s an update from asteroid expert Patrick Michel about the European Space Agency’s Rapid Apophis Mission for Space Safety. The ESA have received permission to begin preparatory work for the planetary defence mission which will rendezvous with the asteroid Apophis, that will be passing by the Earth on Friday, April 13th 2029.

And in news from the Moon this week – a massive cave has been discovered on its surface that might be a window into the body’s sub-surface, and even a ready-made lunar base for future astronauts to use. The claim was made in Nature Astronomy by a team of Italian planetary scientists, and two experts in remote sensing who have been re-interpreting radar data from a NASA orbiter - Leonardo Carrer and Lorenzo Bruzzone from University of Trento in Italy. In the magazine Science, there’s a call for a re-doubling of efforts to tackle malaria in Africa as signs grow that a leading treatment, Artemisinin, is becoming less effective. Deus Ishengoma, a malaria expert with the Tanzanian National Institute for Medical Research, is worried, having seen the transformation Artemesinin made in the past.

Tiny solar-powered flying robots - an ultra-lightweight, solar-powered micro aerial vehicle capable of sustained flight is described in a paper published in Nature. Peng Jinzhe of the School of Energy and Power Engineering at Beihang University was part of the team behind the 8 millimetre robot.
