I’ve argued how the outcome underscores the need for resilience in private lunar landing missions [through expansive and collaborative testing](https://jatan.space/moon-monday-issue-228/)—something former NASA astronaut and current ispace US Chair Ron Garan [has also vouched for](https://spacenews.com/after-resiliences-moon-landing-attempt-why-openness-is-key-to-the-lunar-economy/). One must note that ispace [continued its remarkable transparency](https://jatan.space/moon-monday-issue-228/#tenaciously-transparent) from the first failed landing mission, sharing [detailed findings](https://ispace-inc.com/wp-content/uploads/2025/06/M2-Technical-Cause-Analysis-Materials.pdf) of what went wrong in mere weeks. - The Hawaii-based International Lunar Observatory Association (ILOA) [will fly its ILO-1 telescope](https://iloa.org/the-ilo-mission/) on the crew-capable [FLEX rover](https://www.astrolab.space/flex-rover/) by Astrolab (a Moon Monday sponsor). Astrolab leads one of the three competing teams NASA selected last year to mature their designs for a [versatile Lunar Terrain Vehicle](https://jatan.space/moon-monday-issue-171/) for use across Artemis missions starting end of decade. ## What science will Artemis II do? Zilch? ![](https://jatan.space/content/images/2025/07/artemis-ii-crewed-flight-map.jpg) Artemis II flight map. [Image: NASA](https://www.nasa.gov/humans-in-space/artemis-ii-media-resources/) NASA wrote the following in a [recent release](https://www.nasa.gov/blogs/missions/2025/06/13/nasas-artemis-science-team-inaugurates-flight-control-room/) on its website about the topic: > Artemis II astronauts will observe the Moon during their 10-day mission around the Moon and back, taking photographs and verbally recording what they see. Their observations will support science objectives and provide data for potential landing sites for future Moon missions. Now, [Artemis II](https://www.nasa.gov/mission/artemis-ii) is not even an orbiter mission. The [four-person crew](https://www.nasa.gov/press-release/nasa-names-astronauts-to-next-moon-mission-first-crew-under-artemis) inside Artemis II’s [Orion](https://www.nasa.gov/feature/meet-nasa-s-orion-spacecraft) capsule will be flying [more than 7000 kilometers from the Moon](https://www.nasa.gov/missions/artemis/nasas-first-flight-with-crew-important-step-on-long-term-return-to-the-moon-missions-to-mars/) at their closest approach. What science can they even do from such large distances? And so in less than 10 days? Certainly no landing sites will be selected. While all Artemis II activities will certainly be useful *operationally* to feed forward into [Artemis III](https://www.nasa.gov/missions/artemis/artemis-iii/) and beyond but doing science as an objective in itself is a different ballgame altogether. Now, every space agency does PR pieces. But NASA used to stand out for clearly articulating the scientific motivations and implementations part of its missions. This webpage release is not one of them. **Related:** [*How NASA has been incrementally planning Artemis III science*](https://jatan.space/moon-monday-issue-170/) ## Information sharing enables cutting edge lunar exploration ![](https://jatan.space/content/images/2025/07/jaxa-slim-lander-lunar-surface-image-superimposed-on-ohrc-image-by-isro-chandrayaan-2-orbiter.jpg) The SLIM lander’s images of the Moon (blue boxes) taken from about 50-meter altitudes, superimposed on the background image by ISRO’s Chandrayaan 2 orbiter for navigation. [Image: ISRO / JAXA / SLIM](https://global.jaxa.jp/press/2024/01/20240125-1%5Fe.html) The day was January 19, 2024\. JAXA’s [SLIM](https://www.isas.jaxa.jp/en/missions/spacecraft/current/slim.html) spacecraft just achieved the most precise Moon landing ever for a robotic vehicle, touching down [only 55 meters from its targeted point](https://jatan.space/precision-moon-landings-and-the-future/). A unique enabler of that feat was ISRO, who [shared its Chandrayaan 2 orbiter datasets](https://jatan.space/indian-space-issue-15/) with JAXA for landing site selection as well as for SLIM’s onboard navigation maps. Without the world’s sharpest lunar imager, it wouldn’t be possible for SLIM to spot and navigate to a safe touchdown point without compromising the landing accuracy—the primary mission goal. The two agencies are now collaborating on the joint [LUPEX rover mission](https://jatan.space/indian-space-issue-25/) to study [water ice](https://jatan.space/ultimate-guide-to-water-on-the-moon/) on the Moon’s south pole. It’s a fine example of state actors bridging their unique strengths to gain more than the sum of their parts. There’s also the recent case of international researchers [getting access to lunar samples](https://jatan.space/moon-monday-issue-223/) from China’s [Chang’e 5](https://jatan.space/change-5-landing-site/) mission for detailed scientific studies. One such lab is from the UK’s Open University. The UK does not have an independent lunar landing program but it does have state-of-the-art laboratories and world-class planetary scientists. With the samples, UK researchers are [uniquely advancing](https://www.open.ac.uk/blogs/news/science-mct/ou-space-expert-among-worlds-first-to-receive-moon-rock-samples-for-research/) humanity’s understanding of our Moon’s [origin](https://jatan.space/apollo-moon-origin/) and [evolution](https://jatan.space/the-two-faced-moon/), which in itself is tied to that of Earth and the [history of our Solar System](https://jatan.space/solar-system-history-101/). For China, it also helps maximize the output of its missions. Such data sharing and access are useful not just for enabling cutting-edge lunar exploration but to have it continue safely as well. The US, India, and South Korea [constantly coordinate their polar orbiters](https://jatan.space/a-registry-of-moon-missions/) to avoid uncomfortably close passes with each other. A collision otherwise would render low lunar orbit dangerous for all orbiters while also obstructing surface landers traversing through the region. All of these examples represent commendable efforts from each actor. But unfortunately, they’re also ad hoc or opportunistic in ways that don’t scale with the [increasing pace of Moon missions worldwide](https://jatan.space/moon-monday-issue-231/). Different states share different information at different times, in different formats, and through different channels at varying levels. Information sharing and coordination is thus dispersed, and not efficient for safety, sustainability, or abundant progress. Improving it for more actors can compound perks for all. To that end, in 2025 the non-profit [Lunar Policy Platform](https://lunarpolicyplatform.org/foundation) (LPP) has embarked on the “Lunar Information Sharing 101” initiative. With funding from the [Open Lunar Foundation](https://www.openlunar.org/) (a Moon Monday sponsor) and in synergy with UN COPUOS initiatives, LPP spent five months consulting over 70 representatives from 35 governments, space agencies, companies, and experts to understand converging and diverging views on when, where, and how to share lunar mission information. The resulting document will be released publicly later this year after feedback. You can [read more about the initiative](https://lunarpolicyplatform.org/informationsharing) and [contact LPP](https://lunarpolicyplatform.org/getinvolved) with your feedback and ideas. *This section was originally published by me on the* [*newsletter*](https://www.openlunar.org/newsletter) *of Open Lunar Foundation (a Moon Monday sponsor) as their* [*Science Communications Lead*](https://jatan.space/joining-open-lunar-as-their-science-communications-lead/)*.* --- *There are many ways to contribute to humanity.

[Image: Blue Canyon Technologies](https://www.nasa.gov/blogs/smallsatellites/2025/07/03/spacecraft-bus-commissioning-complete-for-nasas-arcstone/) - Earth observation satellites periodically image the Moon to detect, calibrate, and correct deviations in the performance of their imagers. The latter happens naturally due to aging hardware, degradation of imager material or the coating, radiation exposure, and other such factors. It’s our Moon’s stable and known light intensity that allows it to act as an accurate celestial reference for Earthbound remote sensing satellites. And that’s why NASA [launched](https://www.nasa.gov/blogs/smallsatellites/2025/06/27/successful-liftoff-signal-acquired-for-nasas-arcstone-satellite/) the [Arcstone satellite](https://science.larc.nasa.gov/arcstone/about/) on June 23 to provide state-of-the-art radiometric calibration for Earth Observation satellites. NASA [completed commissioning](https://www.nasa.gov/blogs/smallsatellites/2025/07/03/spacecraft-bus-commissioning-complete-for-nasas-arcstone/) the spacecraft bus on July 3\. NASA [says](https://www.nasa.gov/science-research/science-enabling-technology/nasa-tech-to-use-moonlight-to-enhance-measurements-from-space/) Arcstone is “the first mission exclusively dedicated to measuring lunar reflectance from space as a way to calibrate and improve science data collected by Earth-viewing, in-orbit instruments.” - *Another the way our Moon is useful beyond lunar exploration:* [***Repurposing Moon missions to enable deep space exploration***](https://jatan.space/moon-monday-issue-193/) - The Italian Space Agency (ASI) has [contracted a OHB-led consortium](https://www.asi.it/2025/06/oracle-al-via-il-progetto-italiano-per-lestrazione-di-ossigeno-dalla-regolite-lunare/) to develop the flight payload for the ORACLE project aimed at [extracting oxygen from lunar soil](https://jatan.space/moon-monday-issue-153/). ASI has not selected or announced yet which Moon lander ORACLE will fly on but was previously targeting launch by 2028. - After [three collaborative years ](https://jatan.space/a-registry-of-moon-missions/)of research & development and community consultations, the Open Lunar Foundation (a Moon Monday sponsor) has launched the [Lunar Ledger](https://www.lunarledger.space) (Registry) project in Beta. The ledger of lunar objects and activities hopes to improve operator transparency and public understanding of Moon missions globally. Open Lunar also announced a [multi-country Advisory Board](https://www.lunarledger.space/advisors) for the Ledger.
