Here is the lunar swirl of Reiner Gamma. ![](https://jatan.space/content/images/2024/02/https-3a-2f-2fbucketeer-e05bbc84-baa3-437e-9518-adb32be77984-s3-amazonaws-com-2fpublic-2fimages-2fbbbbe8ab-7263-4171-8de6-6d5162472d55_1000x750-jpeg.jpg) Beautiful and bright lunar swirl of Reiner Gamma.

Interestingly, all swirls on the Moon are associated with a local magnetic field. These fields [protect parts of the swirl’s surface](https://arxiv.org/abs/1605.05778) from being degraded by [the solar wind](https://jatan.space/the-sun-and-its-wind/) and [micrometeorites](https://jatan.space/the-tiniest-of-impact-craters/), making them brighter than their surroundings. On the other hand, the magnetic field lines accelerate solar radiation weathering on regions just besides them. These two mechanisms together are what give [all swirls](http://lroc.sese.asu.edu/posts?page=1&query=swirl) their distinctive bright and dark look. How do (magnetic) swirls form in the first place though? We don’t know. Scientists have some [interesting ideas](https://arxiv.org/abs/1207.2076) on the matter but ultimately we need to precisely measure the local magnetic field strength of regions within the swirl by sending a surface mission. We also need to measure exactly how radiation particles from the solar wind interact with the swirl's magnetic field, and how it affects and shapes the local environment. In November 2021, NASA [funded a commercial Moon mission](https://www.nasa.gov/press-release/nasa-selects-intuitive-machines-for-new-lunar-science-delivery) part of their [CLPS program](https://jatan.space/nasa-clps-moon-missions/) to do exactly that. NASA selected Intuitive Machines to deliver 92 kilograms of science and technology payloads to Reiner Gamma. For a bargain price of $77.5 million, Intuitive Machines will land and jointly operate five rovers and a bunch of science instruments in 2024. ![](https://jatan.space/content/images/2024/02/https-3a-2f-2fbucketeer-e05bbc84-baa3-437e-9518-adb32be77984-s3-amazonaws-com-2fpublic-2fimages-2fbd337403-e8ab-49ef-be13-bc172879ef49_1600x1100-png.jpg) Illustration of Intuitive Machines’ Nova-C lander touching down on the Moon. [Credit: Intuitive Machines](https://www.intuitivemachines.com/post/nasa-selects-intuitive-machines-to-deliver-4-lunar-payloads-in-2024) The mission’s primary payload suite [Lunar Vertex](https://www.jhuapl.edu/NewsStory/211018b-lunar-vertex) is a collection of spectrometers and magnetometers on the lander and a rover. The rover, which Lunar Outpost will provide, will drive up to two kilometers over 13 Earth days, exploring at least one bright and dark section of Reiner Gamma. Lunar Vertex will study the swirl’s composition, and map the strength and direction of magnetic fields on its surface, complementing observations from past orbiters. ![](https://jatan.space/content/images/2024/02/https-3a-2f-2fbucketeer-e05bbc84-baa3-437e-9518-adb32be77984-s3-amazonaws-com-2fpublic-2fimages-2fe765e037-d425-436b-98f7-4756208fa9c3_2189x1440-jpeg-2.jpg) Artist’s impression of the solar-powered Lunar Outpost rover on the Moon with NASA-funded Lunar Vertex instruments.

The other four rovers Intuitive Machines’ lander will carry are part of NASA’s [CADRE project](https://www.nasa.gov/directorates/spacetech/game%5Fchanging%5Fdevelopment/projects/CADRE). The shoebox-sized rovers will autonomously navigate the landed region and collectively better map it than a single rover can. Onboard the lander will also be a South Korean instrument to [monitor high-energy particles](http://planetary.kasi.re.kr/clps) as the Moon passes in and out of Earth’s magnetic tail. The lander will also host an ESA-provided [MoonLIGHT retroreflector](https://www.sciencedirect.com/science/article/abs/pii/S0032063312002814), which will reflect laser beams from Earth to make precise distance measurements so as to infer properties of the Moon’s core, the rate at which the Moon is drifting away from Earth, and test parts of General Relativity. --- This science-packed mission represents a new phase for NASA’s [CLPS program](https://jatan.space/nasa-clps-moon-missions/), to send instruments on commercial lunar landers, enhanced by the recent [PRISM initiative](https://science.nasa.gov/researchers/solicitations/roses-2021/amendment-22-payloads-and-research-investigations-surface-moon-prism-draft-text-released-community). The [second mission in this enhanced phase](https://www.nasa.gov/press-release/nasa-selects-new-science-investigations-for-future-moon-deliveries) will visit the [Schrödinger crater](https://jatan.space/the-crowned-crater-of-schrodinger/) on the Moon’s farside in 2024, for which NASA will announce the winning commercial landing bidder next. The Reiner Gamma landing is Intuitive Machines’ third such NASA contract and also their third Moon mission, to follow their [first](https://7c27f7d6-4a0b-4269-aee9-80e85c3db26a.usrfiles.com/ugd/7c27f7%5Fbc896cfc90ca4ae9a0643bfbf5ed214a.pdf) [two](https://www.nasa.gov/press-release/nasa-selects-intuitive-machines-to-land-water-measuring-payload-on-the-moon) missions in 2022\. All three missions will see the launch of Intuitive Machines’ Nova-C lander on a SpaceX Falcon 9 rocket. --- **→ [Browse the Blog](https://blog.jatan.space/start) | [About](https://blog.jatan.space/about) | [Donate ♡](https://jatan.space/support)**
