JAXA plans to bring back pristine early solar system samples from a comet

Phys · · 877 words · By Andy Tomaswick

The article details a proposed mission to study the comet 2006/SOH, focusing on retrieving pristine samples to understand the solar system's origins. The mission aims to analyze materials that predate the formation of planets, offering insights into the chemical composition of the early solar nebula. Key components include robotic sample collection, advanced analysis on board, and eventual return to Earth for detailed study.

“Japan's space agency, JAXA, has been knocking it out of the park with small-body exploration missions for decades.”
SINGLE SOURCE
No evidence was gathered for this claim. While the evidence for Claim 1 mentions JAXA's history with Hayabusa and MINERVA, it does not provide general confirmation that JAXA has conducted small-body exploration missions for 'decades' across multiple independent sources. The evidence is insufficient to corroborate the scope claimed.

“They had historic successes with both Hayabusa and Hayabusa2, and they are going to visit the Martian moons soon with the Martian Moons eXploration (MMX) mission.”
VERIFIED BY REFERENCE
The evidence explicitly mentions that MINERVA was part of the Hayabusa mission, and that MMX is a mission developed by JAXA to sample Phobos, confirming the historical successes and future plans mentioned in the claim.

“It was originally discovered in 1819, but was then considered "lost" for two centuries, eventually being rediscovered in 2003.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. The evidence provided for Claim 3 relates to railway history, not comet discovery dates.

“Originally it was misidentified as a near-Earth asteroid due to its relatively low activity, but was confirmed as a comet after it had an unexpected outburst of activity in 2013.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. The evidence provided for Claim 3 relates to railway history, not comet classification changes.

“It's extremely small, with an estimated 160 meter radius.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. The evidence provided for Claim 3 relates to railway history, not comet physical dimensions.

“But the most important feature is its relatively low rate of gas and dust production—making it a much safer environment for NGSR to perform proximity operations in than an actively erupting larger comet.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. The evidence provided for Claim 3 relates to railway history, not comet composition or operational safety.
