Tianwen-2 Enters Orbit of Asteroid Kamo'oalewa
2026-06-07 | Near-Earth Object (NEO)
Sample-return spacecraft Tianwen-2 will perform an orbit-insertion burn at asteroid 469219 Kamoʻoalewa on Sunday, June 7, 13 months after its launch in May 2025. It is expected to begin collecting samples early next month. https://www.techtimes.com/articles/317613/20260602/tianwen-2-asteroid-orbit-insertion-set-june-7-amateurs-decode-telemetry.htm
Kamoʻoalewa, formally designated 2016 HO3, was discovered in April 2016 by the Pan-STARRS 1 telescope operated at Haleakala Observatory in Hawaii. It is between 40 and 100 meters in diameter — roughly the size of a large building — and is the smallest asteroid ever to be visited by a spacecraft. The object occupies an unusual quasi-satellite orbit, looping around the Sun in a path that keeps it perpetually near Earth without being gravitationally captured by our planet. That stability will last only about three centuries before gravitational perturbations shift it elsewhere.
What makes Kamoʻoalewa a priority science target is its reflectance spectrum. Unlike most near-Earth asteroids, which tend toward carbonaceous or stony compositions, its spectrum closely resembles the lunar silicate material studied in NASA’s Apollo samples.

Committee on Planetary Protection (CoPP) Online Meeting: Limits of Terrestrial Life and the Probability of Growth on Mars
2026-06-01 - 2026-06-02 | Online
This meeting is to provide information to NASA so it can develop a prioritized list of factors that contribute to the potential release of terrestrial bioburden on the Mars surface and the likelihood of microbial survival and replication. Quantitative and qualitative guidance on individual and multiple growth-limiting/growth-promoting conditions are needed to advance the analysis of planetary protection approaches that enable the search for evidence of life on Mars. Key factors identified during this meeting will assist in modeling the probability of survival and growth of terrestrial organisms in planning for future human and robotic missions to Mars.
The meeting participants will consider:

Current knowledge about microbial persistence and survival in terrestrial, human inhabited, contained environments and control factors used to limit microbial contamination. Considerations will include microbial containment, aseptic controls, and sterilization/containment methodologies. Current knowledge of environmental contamination in analogue martian habitats and previous or existing space missions will be discussed.
Current knowledge about the limits of microbiological growth and survival with a focus on studies that address the probability of survival and growth under known Martian conditions (e.g., nutrient availability, high radiation, low water activity, extreme oxides, cold temperatures, presence/absence of methane).
Identification and prioritization of research gaps for understanding the risk of survival and growth of terrestrial microorganisms on the Martian surface and shallow subsurface.

Meeting deliverables will include: a closing discussion on the prioritization of the topics raised during the meeting, proposals for additional research that may be required to develop a probabilistic risk assessment model for terrestrial microbial survival/growth on the Martian surface, and active dialogue on the next proposed steps.
