Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have as of late gotten tests of the lunar surface that have been painstakingly put away in a cooler at NASA’s Johnson Space Center in Houston since Apollo 17 space explorers returned them to Earth in December 1972.
This exploration is essential for the Apollo Next Generation Sample Analysis Program, or ANGSA, a work to concentrate on the examples got back from the Apollo Program ahead of the forthcoming Artemis missions to the Moon’s South Pole.

“Everything we do involves a lot of logistics and infrastructure, but adding the cold makes it a lot harder. It’s a crucial lesson for Artemis, because the ability to process samples in the cold will be even more critical for the Artemis mission than it was for Apollo. This work provides us with some lessons learned as well as a good direction for Artemis.”Ryan Zeigler
In any case, the method involved in getting the examples from Johnson to analysts at Goddard—as well as scientists at NASA’s Ames Research Center in California’s Silicon Valley, the Naval Research Laboratory in Washington, D.C., and the University of Arizona, Tucson—was significantly more troublesome than you could suspect. A cycle started over a long time ago when NASA’s Julie Mitchell and her Artemis curation group at Johnson started planning and retrofitting an office to handle the frozen Apollo 17 examples. This was another methodology, and researchers were eager to utilize a strategy that could be applied to future lunar missions.
“We began this in mid-2018 and there’s been a ton of specialized difficulties that we’ve needed to overcome to arrive at this point,” said Mitchell. “This was viewed as a training run for setting up an office for future virus test handling.”
“By accomplishing this work, we’re working with Artemis investigation, but we’re working with future example return and human investigation into the remainder of the nearby planet group,” Mitchell added. “I feel exceptionally privileged to contribute in this little manner by fostering the ability for us to gather these materials, bring them home securely, and curate them as long as possible.”
When the office was prepared, Ryan Zeigler, Apollo test custodian in the Astromaterials Research and Exploration Science (ARES) Division at Johnson, and his group needed to adjust to the exceptional circumstances planned by Mitchell’s group to keep the examples frozen during handling, which included diminished perceivability because of ice and difficulties controlling the examples while working with thick gloves in a nitrogen-cleansed glove box, all of which occurred inside a walk-in cooler kept at less than 4 degrees Fahrenheit (short 20 C). Having the option to keep tests frozen will be significant for Artemis as space explorers may possibly return ice tests from the Moon’s South Pole.
“All that we truly do includes a great deal of operations and a ton of framework, yet adding the virus makes it significantly harder,” said Zeigler. “It’s a significant learning illustration for Artemis, as having the option to handle tests in the virus will be considerably more significant for the Artemis mission than it is for Apollo.” This work gives us a few examples learned and a decent feed forward for Artemis. “
When the frozen examples were handled and partitioned at Johnson by lunar example processor Jeremy Kent, the examples were then express transported in a cooler with dry ice, promptly opened at Goddard, and put away in a solid cooler. For the researchers presently working with the fortunes, something really stands out about getting tests that haven’t been examined in anywhere near fifty years.
Frozen Apollo 17 samples are being processed by ARES scientists.
Jamie Elsila, an examination researcher in the Astrobiology Analytical Laboratory at Goddard, is zeroing in on the investigation of little, unpredictable natural mixtures for her exploration and investigation of the example. Past examinations showed that a few lunar examples contain amino acids, which are crucial for life on Earth. Her group must understand their origins and place in the nearby planet group.
“We consider a few of the amino acids in the lunar soils might have been shaped by forerunner atoms, which are more modest and more unpredictable mixtures like formaldehyde or hydrogen cyanide,” said Elsila. “Our examination objective is to distinguish and evaluate these little natural unpredictable mixtures, as well as any amino acids, and to utilize the information to comprehend the prebiotic natural science of the Moon.”
Natalie Curran, head examiner for the Mid Atlantic Noble Gas Research Lab at Goddard, centers around understanding the set of experiences that the examples might have encountered during their lifetime on the Moon. The outer layer of the Moon is a brutal climate and, dissimilar to the Earth, it doesn’t have an atmosphere to safeguard it from openness to space.
“Our work permits us to utilize honorable gases, like argon, helium, neon, and xenon, to quantify the term. An example has been presented to astronomical beams, and this can assist us with figuring out the historical backdrop of that example,” said Curran. “Enormous beams can be harmful to natural material that might be in an example, so understanding the span assists with deciding the impacts that openness has had on the natural.”
Both Elsila and Curran are in control of frozen and non-frozen lunar examples. Whenever these examples were brought to Earth, a piece was put away at room temperature and another part was frozen, considering examination between the two gatherings. Researchers will break down the two arrangements of tests to learn, assuming that there are contrasts in the natural substance. Seeing any varieties brought about by the different curation techniques could illuminate future choices about how to store tests returned by Artemis space explorers, part of what the ARES group at Johnson will do.
For Elsila, “it’s exceptionally cool to contemplate basically everything that went into gathering the examples on the Moon and afterwards all the planning and care that went into safeguarding them for us to have the option to break down right now,” she noted.
With respect to Curran, “when you consider how these examples have come from a different universe, how far they have voyaged, and the nearby planet group history they have protected within them, it generally knocks my socks off,” she added.
