The software on board did a credible job of recognizing nearby craters, even with elongated shadows over the terrain. However, the lander\u2019s altimeter had failed.<\/p>\n<p style=\"\">So while <em>Athena<\/em> knew where it was relative to the surface of the Moon, the lander did not know how far it was above the surface.<\/p>\n<p>An important detail, that. As a result, the privately built spacecraft struck the lunar surface on a plateau, toppled over, and began to skid across the surface. As it did so, the lander rotated at least once or twice before coming to a stop in a small, shadowed crater.<\/p>\n<p>\u201cThe landing was kind of like sliding into second base,\u201d Steve Altemus, chief executive officer of Intuitive Machines, which built the lander, said in an interview Thursday.<\/p>\n<h2>Cold and lonely<\/h2>\n<p>It has been a busy and tiring week for the chief of a company that seeks to help lead the development of a lunar economy. Expectations were high for this, the company\u2019s second lunar landing attempt after its <em>Odysseus<\/em> vehicle became the first private spacecraft to ever make a soft landing on the Moon, last year, before toppling over.<\/p>\n<p>In some ways, this mission was even more disappointing. Because <em>Athena<\/em> skidded across the lunar surface, it dredged up regolith. When it came to a stop, some of this material was blown up into the solar panels\u2014already in a sub-optimal location on its side. The spacecraft\u2019s power reserves, therefore, were limited. Almost immediately, the team at Intuitive Machines knew their spacecraft was dying.<\/p>\n<p>\u201cWe knew we had slid into a slightly shadowed crater, and the temperature was very cold,\u201d Altemus said. \u201cThe solar arrays had regolith on them, and they weren\u2019t charging, the ones pointing up, enough to give us sufficient power to power the heaters to keep it warm enough to survive.\u201d<\/p>\n<p>,<\/p>\n<figure class=\"ars-wp-img-shortcode id-2082154 align-fullwidth\">\n<p>              <img width=\"2560\" height=\"1920\" src=\"https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-scaled.jpg\" class=\"fullwidth full\" alt=\"\" decoding=\"async\" loading=\"lazy\" srcset=\"https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-scaled.jpg 2560w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-640x480.jpg 640w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-1024x768.jpg 1024w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-768x576.jpg 768w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-1536x1152.jpg 1536w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-2048x1536.jpg 2048w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-980x735.jpg 980w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12963-20250307_030144_199963-1440x1080.jpg 1440w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\"><\/p>\n<p>              It\u2019s cold and lonely on the Moon.<\/p>\n<p>                  Credit:<br \/>\n                                      Intuitive Machines<\/p>\n<\/figure>\n<p>The temperature in the crater where <em>Athena<\/em> ended up was approximately minus 280\u00b0 Fahrenheit (minus 173\u00b0 C). With the solar arrays generating only about 100 watts of power, there was not enough energy to both power the spacecraft\u2019s heaters as well as communicate back to Earth using <em>Athena<\/em>\u2018s high-gain antenna. So instead of limping along for 50 hours, mission operators decided to operate as robustly as they could for 13 hours and get down as much data as they could.<\/p>\n<p>During this time the lander was able to accomplish some of its objectives. By landing near the south pole, <em>Athena<\/em> returned valuable data and imagery to NASA about unexplored vistas. The lander extended NASA\u2019s drill (but did not operate it); private customers, including Nokia and Lonestar Data Holdings, were able to get some useful information from their payloads. But there were also some major disappointments. Lunar Outpost could not deploy its small rover, and an innovative hopper could not be fired up to roam across the Moon.<\/p>\n<p>On balance, it was pretty disappointing, especially considering that <em>Odysseus<\/em> still did most of its science last year, even on its side.<\/p>\n<h2>You go back in, start training again<\/h2>\n<p>Yet, what Altemus wants people to understand\u2014which he acknowledges is somewhat difficult to explain\u2014is that this mission was largely a success. What can he possibly mean by that?<\/p>\n<p>Compared to the company\u2019s first spacecraft,&nbsp;<em>Athena<\/em> flew smoothly. During the company\u2019s first lunar flight in 2024, mission operators came into work each shift to put out the fire of the day. By contrast, <em>Athena<\/em> made it all the way to within miles above the Moon without significant problems. In doing so, the company validated the spacecraft\u2019s methane-based propulsion system, which allows for a \u201cfast\u201d transit to the Moon in less than a week. In addition, the company proved out its communications technology that will be used as part of a lunar data relay network that NASA has contracted with Intuitive Machines to develop. Moreover, <em>Athena<\/em> attempted to land within a few degrees of the south pole, a challenging location due to the solar angle and uneven terrain, and made it down without crashing.<\/p>\n<p>,<\/p>\n<p>Of course, the most important thing a lunar lander is supposed to do is <em>land<\/em> on the Moon, which Intuitive Machines did not do successfully. For the second mission in a row, the lander\u2019s altimeter failed. Although it was a different problem with the spacecraft\u2019s altimeter this time\u2014it\u2019s still unclear why <em>Athena<\/em>\u2018s rangefinder failed, perhaps due to a thermal or vibration event\u2014it is frustrating to fail for a similar reason. But all the pieces for success are there, and in the demanding environment of spaceflight, Intuitive Machines is close, Altemus said.<\/p>\n<figure class=\"ars-wp-img-shortcode id-2082155 align-fullwidth\">\n<p>              <img width=\"2000\" height=\"1500\" src=\"https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432.jpg\" class=\"fullwidth full\" alt=\"\" decoding=\"async\" loading=\"lazy\" srcset=\"https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432.jpg 2000w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-640x480.jpg 640w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-1024x768.jpg 1024w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-768x576.jpg 768w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-1536x1152.jpg 1536w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-980x735.jpg 980w, https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2025\/03\/CSYS-12958-20250304_183052_862432-1440x1080.jpg 1440w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\"><\/p>\n<p>              Landing is the most important step.<\/p>\n<p>                  Credit:<br \/>\n                                      Intuitive Machines<\/p>\n<\/figure>\n<p>In an effort to buck up the troops, Altemus&nbsp;has been communicating this message to employees over the last week.<\/p>\n<p>\u201cIt\u2019s like losing a Final Four game or an NBA title,\u201d he said. \u201cYou lose it, and then what do you do?
