NASA’s Johnson Space Center (JSC) needs to collect more samples, but the teams are having trouble opening the canister.
An asteroid sample collected by NASA last month landed in the desert of Utah, carrying to Earth the largest asteroid sample ever collected. On October 11, NASA revealed the first image of the asteroid Bennu, which may provide clues about the origin of life and the early solar system. From the sampler hardware, the team has removed and collected 2.48 ounces (70.3 grams) of rocks and dust. NASA reports that the asteroid debris samples collected exceed the mission’s 60 gram goal.
NASA’s Johnson Space Center (JSC) needs to collect more samples, but the teams are having trouble opening the canister.
OSIRIS-REx’s team has been having difficulties opening the TAGSAM head, which stored the bulk of the rocks and dust collected by the spacecraft in 2020.
With the current tools for use in the OSIRIS-REx glovebox, two of the 35 fasteners on the TAGSAM head could not be removed. NASA wrote in a blog post that its team is developing and implementing new approaches to extract the material inside the head while keeping the sample safe and pristine.
It will now take the team a few weeks to develop and practice a new procedure for removing the remaining asteroid sample from the TAGSAM sampler head while simultaneously processing the material collected this week.
To prevent the sample – and the TAGSAM head – from being exposed to Earth’s atmosphere, all curation work is performed in a specialized glovebox under a flow of nitrogen to preserve its pristine state. ”Any tools that will be used to extract the remaining material from the head must fit inside the glovebox and must not compromise the scientific integrity of the collection. Procedures must also comply with the standards of the clean room,” NASA said.
During the 2010 and 2020 missions, Japan succeeded in bringing back samples from an asteroid for study, but OSIRIS-REx was the first to do so.
Bennu was sampled by NASA because of its abundance of organic compounds. Through collisions billions of years ago, similar asteroids might have delivered organic building blocks and water to Earth.
Until the mid-2100s, the chances of it hitting Earth are zero, but between then and 2300, the chances rise to around 1 in 1750.
