Europe is preparing a mission for a double asteroid

The European Space Agency announced the transition to the next phase of the Hera interplanetary mission project. Its goal will be a 780-meter asteroid 65803 Didyma. The main feature of this asteroid is the presence of a small satellite, designated S / 2003 (65803) 1. It is also known under the unofficial name Didymoon. The satellite has a diameter of only 160 m and rotates around the main asteroid in an orbit with a radius of 1.1 km with a period of 11.9 hours.

Hera is part of a joint European-American project AIDA (Asteroid Impact and Deflection Assessment). Its main task is to collect information on the effects of kinetic effects on small planets. Or, to put it simply - is it possible to reject an Earth-threatening asteroid, if you strike at it?

In general terms, the AIDA plan is as follows. In 2020, NASA should launch the DART (Double Asteroid Redirection Test) spacecraft. In October 2022 he will crash into Didymoon. Ground and space observatories will monitor the course of the impact and assess its impact on the nature of the rotation of the satellite.It is assumed that the collision with the 300-kilogram apparatus will change the orbital speed of the Didymoon by approximately 0.4 mm / s, which in turn will lead to a change in its period of rotation by a few minutes.

In 2023, Hera will go into space. The European station will reach Didim in 2026. It will carefully measure the crater remaining after the DART impact, and will also conduct a comprehensive study of both asteroids. These data will help astronomers to better understand the properties and behavior of such binary systems.

It is assumed that, together with Hera, Didim will also launch a microsatellite based on the CubeSat platform. It will become the first European Kubsat, which set off beyond the limits of the Earth orbit. The ESA uses it to study the possibilities of using devices of a similar class in interplanetary missions, as well as to test a new inter-satellite communication system.
