On September 24, 2023, an interplanetary ship in the United States called Osiris-RexMiningNo oneSpaceshipSmooth return to the vicinity of the Earth. From launch to return to Earth, the probe has been flying for seven years, covering a staggering 6.2 billion kilometers. This magnificent journey came from a mission to explore and collect samples from the Bennu asteroid, making us interested in:SpaceThere is a deeper understanding of the unknown.
The Osiris-Rex probe was launched in 2016 and finally arrived in Bennu on December 31, 2018, after a long journeyAsteroidsNeighborhood. This one is 2 from the earth800 million kilometers awayAsteroidsOn the proximity of the probe, its true colors were revealed. It's not just shootingAsteroidsThe Osiris-Rex probe also successfully landedAsteroidssurface, collected some preciousRocksSamples and dust samples. This marks the first time that humanity has successfully recovered fromAsteroidsSamples were collected.
However, during the sample return process, the Osiris-Rex detector encountered some difficulties. First of all, the detector may have taken too many samples during the collection process, or someRocksThe sample is too large for the sample chamber to be properly sealed. In addition, during the return to Earth, the probe's sample capsule is enteringEarth's atmosphereAfter facing a high temperature of about 2900 degrees Celsius. In order for the probe to land safely, the sample chamber needs to be opened at the right altitude and speedParachuteto slow down further. However, the unexpected happened. When the sample cabin is about 30,000 above the surfacem highEmpty time,ParachuteThe trigger system was accidentally triggered, resulting inParachuteCut off, the sample chamber suddenly accelerated its descent. Fortunately, at an altitude of about 2,700 meters above the surface, the LordParachuteIt was opened, successfully slowing down the descent of the sample capsule and safely landing to the landing site one minute ahead of schedule. AlthoughParachuteThere was an accident, but it didn't work for BennuAsteroidsThe safety of the sample has a negative impact.
However, whenScienceWhen they got their hands on the sample chamber of the Osiris-Rex probe, they encountered a thorny problem: the containment of the sample chamber could not be opened. This is not due to the failure of the detector itself, but due toScienceFamilies to BennuAsteroidsThe purity of the sample is too high. In order to minimize contamination of the sample,ScienceThe specimen chamber was specially designed. Once the sample is collected by the specimen collector, it is placed in the detector's sample chamber and sealed. However, above the specimen collector, there were 35 fasteners, 2 of which were faulty, resulting in:ScienceThey can't turn on the specimen collector properly. In order not to destroy the purity of the sample,ScienceInstead of using violent means to open the specimen collectors, the families are looking for other solutions.
Through this Osiris-Rex mission, we have a deeper understanding of the mystery and vastness of the universe. Although the return process of the probe went through some difficulties, it finally landed safely and successfully brought back BennuAsteroidssamples. However, this mission also revealed that we are in:SpaceChallenges and difficulties remain in the exploration. From the collection of the sample, sealing to the high temperature burning during the return process andParachuteAccidents, every link needs to be carefully planned and carefully operated. In the future exploration, we need to constantly sum up experience and improve technology to cope with more challenges and unknowns. Through such efforts, we can gain a deeper understanding of the mysteries of the universe and pave the way for mankind to explore the universe.
