The good news? The plucky robotic spacecraft is nevertheless able to send back data.<\/p>\n<p>Mission managers at the Houston-based company and at NASA, which is paying $118 million to support Odysseus\u2019 space odyssey, are working on ways to maximize the scientific payback over the next nine or 10 days. \u201cThe vehicle is stable, near or at our intended landing site,\u201d Intuitive Machines CEO Steve Altemus said today during a post-landing briefing at NASA\u2019s Johnson Space Center. \u201cWe do have communications with the lander \u2026 so that\u2019s phenomenal to begin with.\u201d<\/p>\n<p>Just by surviving the descent a day earlier, Odysseus made it into the history books as the first commercial lander to arrive safely on the moon \u2014 and the first U.S.-built spacecraft to do so since the Apollo 17 mission in 1972.<\/p>\n<p><span id=\"more-165864\"\/><\/p>\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\">\n<p>\n<span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" title=\"Odysseus touches down on the moon\" width=\"1110\" height=\"624\" src=\"https:\/\/www.youtube.com\/embed\/MhZ7kB5_22o?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe><\/span>\n<\/p>\n<\/figure>\n<p>It wasn\u2019t easy: Mission managers discovered during a pre-landing maneuver that a safety lock on Odysseus\u2019s laser range-finding system hadn\u2019t been disengaged prior to the probe\u2019s Feb. 15 launch. That rendered the system inoperable.<\/p>\n<p>Altemus said that when he told mission director Tim Crain that the spacecraft would have to land autonomously without its range-finders, \u201chis face got absolutely white, because it was like a punch in the stomach that we were going to lose the mission.\u201d Fortunately, Crain and other mission team members figured out a way to reprogram Odysseus to make use of an experimental laser range-finding system that was included among NASA\u2019s payloads.<\/p>\n<p>\u201cIn normal software development for spacecraft, this is the kind of thing that would have taken a month of writing down the math, cross-checking it with your colleagues, doing some simple calculations to prove the theory by putting it into a simulation, running that simulation 10,000 times evaluating performance,\u201d Crain said. \u201cOur team basically did that in an hour and a half. And it worked.\u201d<\/p>\n<p>Crain said it was serendipitous that the problem was identified during the pre-landing attempt to activate the range-finders. \u201cWe would have probably been five minutes to landing before we would have realized that those lasers weren\u2019t working, if we had not had that fortuitous event,\u201d he said. \u201cSo, serendipity is absolutely the right word.\u201d<\/p>\n<p>The range-finder issue wasn\u2019t the only challenge: Odysseus came in for a landing faster than projected, with a downward velocity of 6 mph and sideward velocity of 2 mph. Altemus said the telemetry suggests that one of the lander\u2019s feet caught on something when it touched down, tipping the phone booth-sized spacecraft over onto its side. Based on its current attitude, Odysseus may be hung up on a rock, stuck in a crevasse or lying on a slope.<\/p>\n<figure class=\"wp-block-image size-large\"><figcaption class=\"wp-element-caption\">Intuitive Machines CEO Steve Altemus uses a scale model of the Odysseus lander to show how far the spacecraft is tipped over on the moon\u2019s surface. (NASA via YouTube)<\/figcaption><\/figure>\n<p>On the day of the landing, Intuitive Machines said Odysseus was upright, but today Altemus said that mistaken assessment was based on \u201cstale telemetry\u201d from the lander\u2019s fuel gauges.<\/p>\n<p>Even though the lander is in an off-kilter position, some of its solar arrays are able to generate power, and some (though not all) of its antennas are in the right orientation to communicate with ground stations back on Earth, Altemus said. Mission managers are working to increase the flow of data from the moon \u2014 including imagery that could show definitively how the lander is lying and whether there\u2019s any damage.<\/p>\n<p>\u201cAs we get more telemetry and turn more things on, we\u2019ll be updating you over the coming days [about] the analysis and the reconstruction of the landing,\u201d Altemus said.<\/p>\n<p>He said NASA\u2019s Lunar Reconnaissance Orbiter is due to fly over the landing area over the weekend and capture views from above. That should help Intuitive Machines and NASA figure out how close Odysseus came to its landing target, near a crater known as Malapert A.<\/p>\n<p>Odysseus\u2019s primary mission is to collect data about the environment in the lunar south polar region. That area is of growing interest because its permanently shadowed craters are thought to contain reserves of water ice that could support future moon bases. NASA is planning to send a crew of astronauts to the lunar south polar region in 2026. <\/p>\n<h2 class=\"wp-block-heading\" id=\"h-a-spicy-mission-to-the-moon\">A \u2018spicy\u2019 mission to the moon<\/h2>\n<p>The past year has demonstrated just how tough it is to put a robotic lander on the moon. Last month, a different private company called Astrobotic missed its chance for a lunar landing when its Peregrine spacecraft developed a propellant leak after launch. Moon landing attempts by Russia\u2019s space agency and Japan\u2019s iSpace venture also fell short. On the plus side, India successfully sent a lander and a rover to the lunar surface last August. And in an eerie foreshadowing of Odysseus\u2019 mission, the Japanese Aerospace Exploration Agency\u2019s SLIM lander made it to the moon \u2014 but tumbled onto its side.<\/p>\n<p>Altemus acknowledged that Odysseus, which is named after a long-wandering hero in Greek mythology, didn\u2019t exactly encounter smooth sailing during its own odyssey. \u201cIt was quite a spicy seven-day mission to get to the moon,\u201d he said.<\/p>\n<p>NASA\u2019s deputy associate administrator, Joel Kearns, praised Intuitive Machines for pulling it off.<\/p>\n<p>\u201cLet me congratulate Intuitive Machines for three major accomplishments,\u201d Kearns said. \u201cThe first is \u2026 for having the first successful soft landing on the moon by the United States since 1972. The second is for being the first non-governmental commercial organization to actually touch down safely on the surface of the moon. And the third is, we\u2019re having a touchdown point 80 degrees south latitude, much closer to the south pole of the moon than any earlier U.S. robotic or human explorers.\u201d<\/p>\n<p>Kearns said NASA has already received valuable data from Odysseus\u2019 transit to the moon, \u201cand we\u2019re looking forward to get even more data as Intuitive Machines finishes the checkout of Odysseus.\u201d<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-what-s-ahead-for-odysseus\">What\u2019s ahead for Odysseus?<\/h2>\n<p>Altemus said it looks as if all of the active payloads should be able to keep collecting data. The only payload in an awkward position is a cube containing an array of mini-sculptures, which is on the lander\u2019s downward-facing side, he said. <\/p>\n<p>A camera system called EagleCam presents a special case: EagleCam was designed to be deployed during the lander\u2019s descent and snap \u201cselfies\u201d of the touchdown, but because of the issue with the range-finding system, the payload had to stay put. Mission managers are currently planning to have the stationary lander eject EagleCam onto the surface to take pictures.<\/p>\n<p>The end of Odysseus\u2019s mission is already drawing nigh. Crain said the lander\u2019s solar arrays will no longer be able to generate power when the sun sets at the landing site.<\/p>\n<p>\u201cOnce the sun sets on Odie, the batteries will attempt to keep the vehicle warm and alive, but eventually it\u2019ll fall into a deep cold,\u201d Crain said<\/p>\n<p>The lander\u2019s electronic circuits aren\u2019t designed to survive that chilly lunar night. \u201cBest-case scenario, we\u2019re looking at another nine to 10 days,\u201d Crain said. \u201cOf course, the next time the sun illuminates the solar arrays, we\u2019ll turn our dishes to the moon, just to see if the radios and the batteries and the flight computers survive that deep cold.\u201d<\/p>\n<div class=\"sharedaddy sd-block sd-like jetpack-likes-widget-wrapper jetpack-likes-widget-unloaded\" id=\"like-post-wrapper-24000880-165864-65d9612fa8c44\" data-src=\"https:\/\/widgets.wp.com\/likes\/#blog_id=24000880&amp;post_id=165864&amp;origin=www.universetoday.com&amp;obj_id=24000880-165864-65d9612fa8c44\" data-name=\"like-post-frame-24000880-165864-65d9612fa8c44\" data-title=\"Like or Reblog\">\n<h3 class=\"sd-title\">Like this:<\/h3>\n<p><span class=\"button\"><span>Like<\/span><\/span> <span class=\"loading\">Loading&#8230;<\/span><\/p>\n<p><span class=\"sd-text-color\"\/><\/div>\n<\/p><\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/www.universetoday.com\/165864\/odysseus-moon-lander-is-tipped-over-but-still-sending-data\/?rand=772204\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The bad news is that Intuitive Machines\u2019 Odysseus lander is tipped on its side after getting tripped up during its touchdown near the south pole of the moon.
