The Sample Collection for Investigation of Mars (SCIM) is a mission concept for a Mars air and dust sample return. It was a semi-finalist at the Mars Scout Program along with four other missions in December 2002.[2][3] The SCIM mission would be designed to skim through the Mars atmosphere without landing or entering orbit.[1] It would collect samples in an aerogel and take them back to Earth on a free-return trajectory.[4]

The success of fellow Discovery program mission Stardust was noted as supporting future sample return missions, and in particular supporting the SCIM concept.[1] This Stardust mission was similar in that it returned extraterrestrial material to Earth with an unmanned robotic spacecraft.[1]

Overview

SCIM would collect air and dust samples by flying through the atmosphere of Mars without landing or orbiting.[5][6] The design utilizes heritage from the successful Stardust and Genesis sample return missions.[6] A pass through the atmosphere about 40 km (25 mi) above Mars' surface at a speed of 6 km/s would result in millions of particles being encountered.[7] The particles would be collected in an aerogel and returned to Earth inside a small sealed capsule.[7] Analysis of the dust could confirm the origin of the suspected meteorites on Earth from Mars.[7]

SCIM was studied in 2002 for the 2007 Mars Scout Program mission as a relatively low-cost, low-risk Mars sample return.[2][5] It achieved semifinalist status.[4][8] The other semifinalist missions were ARES, Phoenix, and MARVEL (Mars Volcanic Emission and Life Scout).[2] ARES was a powered Mars aircraft, Phoenix was a polar lander, and MARVEL was an orbiter.[9]

Private funding proposal

In 2014 the BoldlyGo organization stated their intention of raising money for this mission privately.[10] They stated that many space missions are not being flown due lack of funds, not because there are issues with the proposals.[10]
