\nAs part of ESA\u2019s proposed Asteroid Impact Mission would come the Agency\u2019s next landing on a small body since Rosetta\u2019s Philae lander reached 67P\/Churyumov\u2013Gerasimenko in 2014.\n<\/p>\n
\nIn 2022 the Mascot-2 microlander would be deployed from the main AIM spacecraft to touch down on the approximately 170-m diameter \u2018Didymoon\u2019, in orbit around the larger 700-m diameter Didymos asteroid.\n<\/p>\n
\nThe 15 kg Mobile Asteroid Surface Scout-2 (Mascot-2) is building on the heritage of DLR\u2019s Mascot-1 already flying on Japan\u2019s Hayabusa-2. Launched in 2014, the latter will land on asteroid Ryugu in 2018.\n<\/p>\n
\nMascot-2 would be deployed from AIM at about 5 cm\/s, and remain in contact with its mothership as it falls through a new inter-satellite communications system. Didymoon\u2019s gravity levels will only be a few thousandths of Earth\u2019s, so the landing would be relatively gentle, although multiple bounces may take place before it comes to rest.\n<\/p>\n
\nLight-emitting diodes (LEDs) would help AIM to pinpoint its microlander\u2019s resting place from orbit. In case of a landing in a non-illuminated area, a spring-like \u2018mobility mechanism\u2019 would let the microlander jump to another location. Onboard GNC \u2018guidance navigation and control\u2019 sensors would gather details of the landing both for scientific reasons and to determine the microlander\u2019s orientation for deployment of the solar array to keep it supplied with sufficient power for several weeks of surface operations.\n<\/p>\n
\nAs well as a solar array, AIM would also deploy its low frequency radar LFR instrument, while cameras perform visible and thermal surface imaging.
