MOSCOW (Skoltech PR) — Researchers from Skoltech and the Massachusetts Institute of Technology have analyzed several dozen options to pick the best one in terms of performance and costs for the ‘last mile’ of a future mission to the Moon – actually delivering astronauts to the lunar surface and back up to the safety of the orbiting lunar station. The paper was published in the journal Acta Astronautica.

For the first time, an international team has drawn up a list of the 50 most dangerous space debris in low orbit. This unpublished Top 50 is published online on January 22, 2021 by the journal Acta Astronautica.

PARIS (CNES PR) — It is a landmark article. For the first time, space debris in low orbit (located at an altitude of less than 2,000 km) has been classified according to their dangerousness for operational satellites by a team that includes experts from China, the United States and Russia. France via CNES is one of the signatories of this historic paper published on January 22, 2021 by Acta Astronautica and whose results had already been presented, in October 2020, at the 71st International Astronautical Congress (IAC2020).
