After collecting samples from the asteroid Ryugu, the Japanese probe Hayabusa2 dropped a capsule containing the substance in Australia last week. Inside, black sand and gaseous matter were discovered from this primitive solar system object.
This Japan Aerospace Agency (JAXA) already confirmed That is your probe ab bird 2 The solid and gaseous samples collected in 2019 have been brought to Earth Asteroid LongguMove around the sun in an orbit between Mars and the earth.
Before it passed near our planet and continued to other objects in the solar system, the Japanese probe issued a Capsule with material Collected a desert area Woomera, Australia, Mission researchers recovered it on December 6.
The first quick inspection and analysis was carried out the next day In situ In a named Quick View Facility (QLF), And sent the samples to Japan on December 8th at Sagamihara JAXA campus.
After carefully opening the space capsule and its various sediments, Japanese researchers confirmed this week that there were black sand grains, surprising them in number and size (up to a few millimeters), as well as asteroid gas.
This is true for the mass spectrometry results performed at the QLF facility in Australia and subsequent mass spectrometry results obtained at the QLF laboratory. Extraterrestrial Sample Management Center At the Sagamihara Japanese campus, they agreed that the gas came from Ryugu.
Another point that the researcher wants to confirm is that the container of the sample container maintains a good seal. Aluminum guardrail In the design state, “to keep the inclusions in the earth’s atmosphere below the height allowed during the mission.”
In addition, they added, “Since Sagamihara confirmed that even if the gas is taken out of the Australian container, a gas with the same composition is generated, so it is believed that the gas must be generated by degassing the sample.” In any case, it is gaseous matter from asteroids or their rocks.
The Hayabusa2 mission leader said: “This is the world’s first sample of gaseous material from deep space.” They will continue to check what the probe brings and perform detailed analysis of molecules and isotopes on the composition of the collected gas.
Unprecedented material on earth
“Studies in 2019 and 2020 have shown that the Dragon Palace is darker than any meteorite found on Earth, and Significantly porousTherefore, these samples are likely to be very different from the samples we have obtained so far,” the researchers explained to Sinc. Eri Tatsumi (Eri Tatsumi) From the Institute of Astronomy, Canarias University, co-author of some of these works.
“The next step will be at first glance, mainly based on Reflectance spectrum There is no need to destroy them,” Tatsumi added.
“Scientifically speaking-he continues-the hydration state and organic composition of the sample will be the first to be studied because it is directly related to life on earth.”
“If this material is different from a meteorite on Earth, then the Longgu sample may be The missing part of solar system history“The conclusion is a scientist. He hopes to see “new discoveries” in the near future.
