V missions with extreme caution, and later studies by the NRC and ESF agreed. Sample-return missions First missions The Apollo program returned over of lunar rocks and regolith (including lunar 'soil') to the Lunar Receiving Laboratory in Houston. Today, 75% of the samples are stored at the Lunar Sample Laboratory Facility built in 1979. In July 1969, Apollo 11 achieved the first successful sample return from another Solar System body. It returned approximately of Lunar surface material. This was followed by of material and Surveyor 3 parts from Apollo 12, of material from Apollo 14, of material from Apollo 15, of material from Apollo 16, and of material from Apollo 17. One of the most significant advances in sample-return missions occurred in 1970 when the robotic Soviet mission known as Luna 16 successfully returned of lunar soil. Likewise, Luna 20 returned in 1974, and Luna 24 returned in 1976. Although they recovered far less than the Apollo missions, they did this fully automatically. Apart from these three successes, other attempts under the Luna programme failed. The first two missions were intended to outstrip Apollo 11 and were undertaken shortly before them in June and July 1969: Luna E-8-5 No. 402 failed at start, and Luna 15 crashed on the Moon. Later, other sample-return missions failed: Kosmos 300 and Kosmos 305 in 1969, Luna E-8-5 No. 405 in 1970, Luna E-8-5M No. 412 in 1975 had unsuccessful launches, and Luna 18 in 1971 and Luna 23 in 1974 had unsuccessful landings on the Moon. In 1970, the Soviet Union planned for a 1975 first Martian sample-return mission in the Mars 5NM project. This mission was planned to use an N1 rocket, but as this rocket never flew successfully, the mission evolved into the Mars 5M project, which would use a double launch with the smaller Proton rocket and an assembly at a Salyut space station. This Mars 5M mission was planned for 1979, but was canceled in 1977 due to technical problems and complexity; all hardware was ordered destroyed. 1990s The Orbital Debris Collection (ODC) experiment deployed on the Mir space station for 18 months in 1996–97 used aerogel to capture particles from low Earth orbit, including both interplanetary dust and man-made particles. 2000s The next mission to return extraterrestrial samples was the Genesis mission, which returned solar wind samples to Earth from beyond Earth orbit in 2004. Unfortunately, the Genesis
