On Feb. 7, 1999, the Stardust mission launched. The primary-of-its-kind sample-return mission was commissioned with flying via the coma of Comet Wild 2, accumulating mud particles, after which bringing these particles again to Earth.
On Nov. 2, 2002, the spacecraft made a apply run previous asteroid 5535 Annefrank to make sure the tools was functioning accurately for its encounter with its goal. The craft featured an autonomous navigation system in addition to a sample-collector that resembled a tennis racket. This device was crammed with aerogel – a silica-based substance that might protect the composition and isotopic traits of the mud it caught. On Jan. 2, 2004, Stardust flew by Comet Wild 2 at a distance of 150 miles (241 kilometers), and efficiently captured over 10,000 particles. The spacecraft then set off on its return journey to Earth, and on Jan. 15, 2006, the sample-return capsule separated from the craft and entered Earth’s ambiance at over 28,000 mph (12.8 km/s). It efficiently parachuted to a touchdown within the Utah desert. The particles Stardust had collected revealed new particulars in regards to the commonality of the constructing blocks of life within the universe, and the circumstances underneath which the photo voltaic system fashioned.
