航空航天研究与发展组织(JAXA):

关于“胶囊内确认的黑沙颗粒样品”的在线新闻发布会举行了。

12月15日,“ Hayabusa 2”号飞船返回地球。

我检查了胶囊的内部。

我们举行了有关黑沙颗粒样品的在线新闻发布会。

津田雄一教授:

他说:“显然已经证实,有许多(从胶囊中)从Ryugu收集的沙子。”

根据JAXA:

返回日本后,调查中在“早H 2号”胶囊中检测到的气体不在地球上。

证实它来自小行星龙宫。

JAXA | Analysis results from the gas collected from the sample container of the asteroid explorer, Hayabusa2

December 15, 2020 (JST)

National Research & Development Agency Japan Aerospace Exploration Agency (JAXA)  

The Japan Aerospace Exploration Agency (JAXA)

has confirmed that the gas collected from the sample container inside the re-entry capsule of the asteroid explorer,

Hayabusa2, is a gas sample originating from asteroid Ryugu.  

The result of the mass spectrometry of the collected gas within the sample container

performed at the QLF (Quick Look Facility) established at the Woomera Local Headquarters in Australia on December 7, 2020,

suggested that the gas differed from the atmospheric composition of the Earth.

For additional confirmation, a similar analysis was performed on December 10 – 11 at the Extraterrestrial Sample Analysis results from the gas collected from the sample container of the asteroid explorer, Hayabusa2 Curation Center on the JAXA Sagamihara Campus.

This has led to the conclusion that the gas in the sample container is derived from asteroid Ryugu.  

The grounds for making this decision
are due to the following three points.

Gas analysis at the Extraterrestrial Sample Curation Center and at the Woomera Local Headquarters in Australia gave the same result.

The sample container
is sealed with an aluminum metal seal and the condition of the container is as designed, such that the inclusion of the Earth’s atmosphere was kept well below the permissible level during the mission.

Since it was confirmed on the Sagamihara campus that gas of the same composition had been generated even after the removal of the container gas in Australia, it is considered that the collected gas must be due to the degassing from the sample.  

This is the world’s first sample return of a material in the gas state from deep space.  
The initial analysis team
will continue with opening the sample container and performing a detailed analysis of the molecular and isotopic composition of the collected gas
