[Image: NASA / Josh Valcarcel](https://www.nasa.gov/general/nasa-viper-robotic-moon-rover-team-raises-its-mighty-mast/) NASA’s upcoming [VIPER rover](https://jatan.space/nasa-viper-mission/), part of the agency’s [CLPS program](https://jatan.space/nasa-clps-moon-missions/) designed to study [water ice](https://jatan.space/ultimate-guide-to-water-on-the-moon/) on the Moon’s south pole, is progressing well in its assembly, with the latest hardware addition being [its tall mast](https://www.nasa.gov/general/nasa-viper-robotic-moon-rover-team-raises-its-mighty-mast/). The multipurpose mast hosts a pair of pan-able, steerable panoramic stereo navigation cameras, two LED headlights, and [gimballing communications antennas](https://www.nasa.gov/centers-and-facilities/ames/engineers-test-vipers-very-nimble-gimbal/) which can maintain their orientation even as VIPER moves in various directions. VIPER intends to explore areas in and around [permanently shadowed regions](https://jatan.space/permanently-shadowed-regions-on-the-moon/) for over four months to unravel the nature of lunar [water ice](https://jatan.space/ultimate-guide-to-water-on-the-moon/) deposits, assess their resource potential, and help determine how accessible they really are. This will help NASA plan crewed [Artemis](https://www.nasa.gov/feature/artemis/) missions. While VIPER was nominally being planned for a November 2024 launch onboard Astrobotic’s Griffin lander, the company’s [failed](https://jatan.space/moon-monday-issue-159/) lunar mission last month might induce delays, and very likely more tests and associated costs/funds. *Also see:* [*Astrobotic to fly its novel CubeRover on the Griffin lander after all*](https://jatan.space/moon-monday-issue-172/#astrobotic-to-fly-cuberover-on-griffin-after-all) ## ispace doubles down on farside Moon mission ![](https://jatan.space/content/images/2024/04/ispace-us-apex-moon-lander-illustration.jpg) Illustration of the APEX 1.0 lunar lander design by ispace US. [Image: ispace](https://ispace-inc.com/news-en/?p=4781) ispace Japan is taking a [bridge loan of $45 million](https://ispace-inc.com/news-en/?p=5282) from the Sumitomo Mitsui Banking Corporation to majorly continue work on [Draper’s first CLPS Moon mission](https://jatan.space/moon-monday-issue-87/) targeting a 2026 launch, wherein ispace’s [US subsidiary](https://ispace-inc.com/news-en/?p=4781) is providing the [APEX](https://jatan.space/moon-monday-issue-147/) lander to touchdown on the Moon’s farside. Relatedly, Jeff Foust [reported](https://spacenews.com/japanese-lunar-lander-company-ispace-raises-53-5-million-in-stock-sale/) last month that the [publicly traded](https://spacenews.com/first-ispace-mission-ready-for-lunar-landing-as-company-stock-starts-trading/) company raised $53.5 million through a stock sale, $47 million of which will be used for the Draper-led mission. At 300 kilograms, APEX has 10 times more payload capacity than the compact Series 1 lander design, which ispace Japan flew on the company’s [Mission 1](https://jatan.space/ispace-japan-m1-moon-mission/) (M1) last year, and will do so again this year for [M2](https://jatan.space/moon-monday-issue-154/). In October 2023, ispace announced being awarded a [$80 million Japanese government grant](https://ispace-inc.com/news-en/?p=4943) to develop and launch a lunar lander by 2027, which can carry more than 100 kilograms of payload to the Moon’s surface. Some amount of the bridge loan will also go towards the development of this mission. To meet the Draper-led CLPS mission’s science goals, APEX will also deploy two Blue-Canyon-provided [lunar satellites](https://www.draper.com/press-release/nasa-awards-draper-73-million-deliver-suite-payloads-moon-2025) to relay communications between the lander and Earth. Post this primary mission, ispace will move the satellites into a polar orbit to [provide commercial communications](https://ispace-inc.com/news-en/?p=5301) between Earth and hardware on the Moon’s south pole for several years. As a tangent, recall that each of these satellite will also carry a [NASA-grant-funded](https://www.nasa.gov/centers-and-facilities/armstrong/nasa-selects-nine-technologies-for-commercial-flight-tests-2/) payload from Rhea Space called the Jervis Autonomy Module (JAM), which will let the satellites autonomously determine their orbits by imaging and identifying multiple celestial objects. As such, they won’t need to rely on terrestrial ground stations to know their positions. Rhea Space [says](https://www.rheaspaceactivity.com/post/rhea-space-activity-expands-lunar-intelligence-lunint-business-with-two-lunar-payloads) they’re also adapting JAM to capture high-resolution images of the Moon’s surface for mapping purposes. --- *Many thanks to* [***The Orbital Index***](https://orbitalindex.com)*,* [***Gurbir Singh***](https://gurbir.co.uk) *and* [***Arun Raghavan***](https://arunraghavan.net) *for sponsoring this week’s Moon Monday.

[Image: NASA](https://www.nasa.gov/feature/nasa-industry-to-mature-vertical-solar-array-technologies-for-lunar-surface) - NASA is further funding [Ceres Robotics](https://www.ceresrobotics.com) to develop their [50-plus-kilowatt vertical solar arrays](https://www.einnews.com/pr%5Fnews/706663813/ceres-robotics-inc-announces-moonpower-lunar-grid-and-wins-nasa-contract) for potential deployment on [maximally sunlit sites](http://lroc.sese.asu.edu/posts/271) on the Moon’s south pole in support of future crewed Artemis missions. That’s a minimum five fold increase in power than the 10-kilowatt vertical arrays for which NASA made [developmental awards](https://www.nasa.gov/press-release/three-companies-to-help-nasa-advance-solar-array-technology-for-moon) to Astrobotic, Honeybee Robotics, and Lockheed Martin. Ceres says their 23.5-meter tall arrays called C-Towers—being prototyped in partnership with Voyager Space—can auto-deploy, retract for relocation, track the Sun, stay stable on steep terrain, and be resistant to abrasive lunar dust all while minimizing mass and stowed volume for easing their launch and delivery to Luna. - NASA published a [source selection statement](https://sam.gov/opp/68c8ce37ec2d40689a7335d5dbf1f6eb/view) on April 9, providing details on how the agency [selected](https://www.nasa.gov/news-release/nasa-selects-companies-to-advance-moon-mobility-for-artemis-missions/) teams led by Intuitive Machines, Lunar Outpost, and Venturi Astrolab to mature their respective designs for a [versatile Lunar Terrain Vehicle](https://jatan.space/moon-monday-issue-171/) (LTV). NASA intends to use this unpressurized rover on a firm, fixed price service basis across Artemis missions starting with [Artemis V](https://jatan.space/moon-monday-issue-128/) end of decade. The selection statement reveals that NASA ruled out proposals from Leidos, Astrobotic, and Blue Origin. Jeff Foust [highlights more such notable points](https://spacenews.com/nasa-document-outlines-selection-of-lunar-rover-companies/) from the statement but what stood out to me is that Astrolab proposed delivering their LTV earlier than NASA asked for by flying aboard the SpaceX Starship lander that will [carry crew for Artemis IV](https://www.nasa.gov/press-release/nasa-awards-spacex-second-contract-option-for-artemis-moon-landing-0). - Eric Berger [reports](https://arstechnica.com/space/2024/04/nasa-may-alter-artemis-iii-to-have-starship-and-orion-dock-in-low-earth-orbit/) that NASA is privately considering modifying the upcoming [Artemis III](https://www.nasa.gov/missions/artemis/artemis-iii/) crewed Moon landing mission to an Earth or lunar orbiting one in order to gain confidence that the [Orion spacecraft](https://www.nasa.gov/feature/meet-nasa-s-orion-spacecraft) and [Lunar Starship](https://www.nasa.gov/news-release/as-artemis-moves-forward-nasa-picks-spacex-to-land-next-americans-on-moon/) can safely dock with each other, and then to test out the latter’s habitability systems. If NASA decides to go ahead with this or another such non-lunar-landing plan, the mission might be called Artemis IIS in Apple style. - In the week of April 15, [Switzerland](https://www.nasa.gov/news-release/nasa-welcomes-switzerland-as-newest-artemis-accords-signatory/), [Sweden](https://www.nasa.gov/news-release/nasa-embraces-sweden-as-newest-member-of-artemis-accords-family/), and [Slovenia](https://www.nasa.gov/news-release/slovenia-signs-artemis-accords-joins-pursuit-of-safer-space/) signed the US-led [Artemis Accords](https://www.nasa.gov/artemis-accords) for cooperative lunar exploration, bringing the total number of nation-signees to 39 globally and 17 in Europe. 🌗 ***Reminder:** *There are now dedicated pages for NASA’s* [**Artemis*](https://jatan.space/tag/artemis/) *and* [**CLPS*](https://jatan.space/tag/clps/) *programs on my blog so you can now browse my ongoing contextual coverage of both topics with ease.* ## More Moon - Continuing to defy JAXA’s own expectations, the solar-powered [SLIM lander](https://jatan.space/moon-monday-issue-161) survived the frigid lunar night for the third time and [reestablished contact](https://twitter.com/SLIM%5FJAXA/status/1783330118683050427) with Earth on April 23\. SLIM has faced some hardware deterioration, which combined with hot temperatures around the near-equatorial-noon have sadly meant that JAXA has been unable to operate SLIM (other than limited use of the optical imager) to specifically continue some of its leftover science goals. - As part of the ongoing [five-year, CAD $150 million](https://www.asc-csa.gc.ca/eng/news/articles/2023/2023-03-29-significant-investments-to-further-propel-canadian-space-exploration.asp) lunar exploration program called [LEAP](https://www.asc-csa.gc.ca/eng/funding-programs/programs/leap), Canada is investing only [CAD $8.6 million](https://ici.radio-canada.ca/rci/en/news/2065797/budget-national-space-council) for the fiscal year 2024-25\. The creation of a National Space Council as part of the budget announcement is welcome news though. - Laser Zentrum Hannover and TU Berlin, with €4.75 million in funding from the German Space Agency, [aim to demonstrate](https://www.astrobotic.com/next-step-toward-the-moon-lzh-and-tu-berlin-partner-with-astrobotic/) laser-melted 3D printing on the Moon on Astrobotic’s [third lunar mission](https://www.astrobotic.com/astrobotic-purchases-falcon-heavy-launch-services), which aims for a south polar touchdown in 2026\. Relatedly, NASA [is awarding](https://www.nasa.gov/press-release/nasa-partners-with-american-companies-on-key-moon-exploration-tech) Astrobotic with $34.6 million to [demonstrate power transmission](https://jatan.space/moon-monday-issue-138/) on the Moon, which seems to be planned to take place as part of the same mission hosting the 3D printing demo. - Andrew Jones [reports](https://spacenews.com/nicaragua-signs-up-to-chinas-ilrs-moon-program/) that on April 24, Nicaragua became the tenth country to join the upcoming China-led long-term [scientific base](https://jatan.space/moon-monday-issue-120/#more-on-the-sino-russian-moonbase) on the Moon’s south pole called the [International Lunar Research Station](https://jatan.space/moon-monday-issue-32/) (ILRS). Also, Ling Xin [reports](https://www.scmp.com/news/china/science/article/3259734/two-major-space-institutes-africa-join-china-led-moon-project) that Ethiopia’s Space Science and Geospatial Institute (SSGI) and the Kenya Advanced Institute of Science and Technology (KAIST) signed intents to join ILRS as organizations. Per the Global Times, the Arab Union for Astronomy and Space Sciences [seems to have joined](https://www.globaltimes.cn/page/202404/1311177.shtml) ILRS as an organization as well.
