More than 50 years after Apollo 17, SpaceX\u2019s Falcon 9 launched Intuitive Machines\u2019 robotic Nova-C lander, named Odysseus, on the beginnings of a lunar journey.<\/p>\n<p>The mission, dubbed IM-1, lifted off at 1:05 a.m. EST (0605 UTC) at Launch Complex 39A. It kicks off a roughly eight-day journey to the Moon, culminating in a landing late in the day on Feb. 22.<\/p>\n<p>IM-1 is the second flight for NASA\u2019s Commercial Lunar Payload Services (CLPS) program. NASA purchased space for six scientific instruments at a cost of just under $118 million. The agency spent about $11 million to design and build the instruments.<\/p>\n<p>Among those are cameras that will help create a 3D rendering of the dust kicked up at landing, a tech demonstration that will help with future landing accuracy and sensor that uses radio waves to detect how much propellant is inside the lander.<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/zazdwjw2xAQ\" width=\"678\" height=\"381\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>Ahead of the launch, Spaceflight Now and CBS News jointly spoke with Steve Altemus, the CEO of Intuitive Machines about reaching this milestone after years of work and planning. During his time working at NASA\u2019s Kennedy Space Center, he held a number of positions within the Space Shuttle Program, especially concerning launch and landing.<\/p>\n<p>\u201cEvery time before I launched the Space Shuttle, I would spend some quiet time with the rocket, the tank and the orbiter and get one with the shuttle and listen to it and talk to it and feel the energy of the machine,\u201d Altemus said. \u201cI wanted to do that here and coming full circle back to Pad A and see the Falcon 9 5500 sitting there with our Nova-C, Odie lander, the nickname of our lander on top, I just wanted to be there with it and get a sense of it.\u201d<\/p>\n<p>The pad was specially outfitted by SpaceX to support this mission. The lander is fueled by liquid methane and liquid oxygen (LOX), a departure from the kerosene and LOX-fueled Falcon 9 rocket.<\/p>\n<p>This past Thursday and Saturday, SpaceX and Intuitive Machines performed a series of fueling tests, known as wet dress rehearsals, where they tweaked the timing of propellant load to be most ideal for the lander. Because the Nova-C lander uses cryogenic fuel, its tanks need to be filled close to liftoff.<\/p>\n<p>Altemus described Thursday\u2019s test as \u201cquite a feat\u201d that went successfully the first time. He said they performed a second test on Saturday in order to make sure they had the timing where they wanted it.<\/p>\n<p>During that test, Altemus said there were some \u201cminor ground support equipment leaks\u201d with both the methane and LOX side, but the LOX leak didn\u2019t require repairs.<\/p>\n<p>During a prelaunch briefing, Bill Gerstenmaier, the vice president of Build and Flight Reliability at SpaceX, said that the two companies worked closely together, both at the Cape as well as in Houston, Texas, to reduce risk on this new fueling capability.<\/p>\n<p>\u201cTo be part of the lunar program and to be part of an activity taking these payloads to the surface of the Moon, which will actually help in the Artemis program in the future, is a tremendous honor for us at SpaceX,\u201d Gerstenmaier said. \u201cWe wanted to give it our best, so we worked as hard as we can with Intuitive Machines to buy down all the risk we can and we\u2019ll see how much our hard work pays off as we go.\u201d<\/p>\n<figure id=\"attachment_65342\" aria-describedby=\"caption-attachment-65342\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65342\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM1_pad2_AB.jpeg\" alt=\"\" width=\"876\" height=\"584\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM1_pad2_AB.jpeg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM1_pad2_AB-300x200.jpeg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM1_pad2_AB-678x452.jpeg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM1_pad2_AB-768x512.jpeg 768w\" sizes=\"(max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65342\" class=\"wp-caption-text\">A SpaceX Falcon 9 rocket at Launch Complex 39A at NASA\u2019s Kennedy Space Center. Onboard is Intuitive Machines\u2019 Nova-C lander. Image: Adam Bernstein\/Spaceflight Now<\/figcaption><\/figure>\n<p>About three hours before liftoff, teams began loading the roughly 1,200 kg of propellant onto the lander. Once fueled, the lander weighs about 2,030 kg. The ratio of LOX to liquid methane is 2.3 to 1, according to Intuitive Machines.<\/p>\n<p>\u201cSpaceX put a LOX and a methane tank just dedicated to filling the lander itself and then they fill from other dewars for their RP-1 (kerosene) and LOX for their vehicle,\u201d Altemus said.<\/p>\n<p>Unlike fueling the Falcon 9 rocket, Artemus said the Nova-C lander has the ability to hold the fueling process and \u201cjust let the tanks lock up with their sub-cold temperatures.\u201d<\/p>\n<p>\u201cThey might get to boil off before we actually lift off, but we can hold and our planned hold is about 45 minutes for the LOX and the methane before we lift off,\u201d Altemus said.<\/p>\n<p>He described \u201csub-cooled\u201d as the point at which the LOX reaches about -300 degrees Fahrenheit and the methane reaches about -280 degrees.<\/p>\n<p>\u201cWhat will happen is that\u2019s densified and it serves to provide more energetic propulsion on the way out to the Moon,\u201d Altemus said. \u201cBetter mixture, better energy out of the propellants, if they\u2019re sub-cooled.\u201d<\/p>\n<p>Trent Martin, the vice president of Space Systems for Intuitive Machines, added that fueling wraps up about an hour before launch, giving them about 20 minutes to ensure that they\u2019re satisfied with the fill level and the temperatures of the cryogenics before the start of propellant load on the Falcon 9.<\/p>\n<p>\u201cAnd then just about 10 minutes or so before launch, we seal up the system and lock it off and it\u2019s ready for launch,\u201d Martin said. \u201cIt\u2019s a choreography that has been rehearsed now a couple of times.\u201d<\/p>\n<p>Intuitive Machines has three, instantaneous launch windows over three days. The March window is predominantly the same, with those dates being March 14-16.<\/p>\n<h4>Path to the Moon<\/h4>\n<p>Following spacecraft separation about 48 minutes after liftoff, teams with Intuitive Machines will go through the process of acquiring the signal from the lander and begin the process of initial checkouts. About 18 hours after that, the lander performs a brief, but important test burn of the main engine called a \u201ccommissioning burn.\u201d Martin described it as a \u201ccritical step\u201d before they can move through the rest of the mission.<\/p>\n<p>\u201cWe have to prove that that engine actually functions in the vacuum of space. We\u2019ve never been able to do that because we haven\u2019t been in space,\u201d Martin said.<\/p>\n<p>He noted that they have tested the igniter in a vacuum environment, which proved successful. Martin said because no other company has launched a methalox engine in deep space, they don\u2019t have any precedent to lean upon.<\/p>\n<p>\u201cSo, when we get to that point, we light that engine, we burn it for a short duration, just to prove that the engine can light and fire,\u201d Martin said. \u201cIt does take the stress level down a little bit and brings the probability of success up a little bit.\u201d<\/p>\n<figure id=\"attachment_65343\" aria-describedby=\"caption-attachment-65343\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65343\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_Nova-C_engine_testing.jpg\" alt=\"\" width=\"876\" height=\"494\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_Nova-C_engine_testing.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_Nova-C_engine_testing-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_Nova-C_engine_testing-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_Nova-C_engine_testing-768x433.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65343\" class=\"wp-caption-text\">Intuitive Machines performing a firing test of its the 900 lbf thrust class VR900 engine, which will power the Nova-C lander. Image: Intuitive Machines<\/figcaption><\/figure>\n<p>The choice of a methalox-fueled lander was because Intuitive Machines believes \u201cit\u2019s the future of this technology,\u201d Martin said. He noted that the company performed more than 150 test firings on dozens of iterations of the main engine that powers the Nova-C lander.<\/p>\n<p>\u201cWe\u2019ve taken the engine that\u2019s sitting on that spacecraft, with that spacecraft, and fired it as a test fire to prove that that engine will light on the vehicle,\u201d Martin said. \u201cWe\u2019ve done multiple filling operations to prove that we can fill with liquid oxygen and liquid methane and we can flow them at the right rates and ignite them at the right time. And we\u2019ve been able to test the throttle ability of the engine.<\/p>\n<p>\u201cThat\u2019s extremely important because as you go to land on the surface of the Moon, you\u2019re going to lose two-thirds of the mass that you started with. You\u2019re going to lose it as you burn it up. So, you have to be able to throttle back that engine to a much lower level than the 100 percent that you started with.\u201d<\/p>\n<p>Once the lander completes the engine commissioning, there are up to three trajectory correction maneuvers that are short firings of just a second or two. That\u2019s followed by the lunar orbit insertion (LOI) burn, which lasts about seven minutes.<\/p>\n<p>The lander will then fly in a circular, low lunar orbit (LLO) of 100 kilometers above the Moon\u2019s surface for about 24 hours, which is followed by the descent orbit insertion (DOI), which comes about 75 minutes ahead of landing.<\/p>\n<p>The DOI coast to the powered descent initiation (PDI) is about an hour, setting up a roughly 15-minute burn through landing. During that process, the lander will shift from a horizontal position to a vertical one. Martin said having an engine that throttles for the final burn helps give them confidence in this final phase of the mission.<\/p>\n<p>He said during the acceptance testing of the engine powering the Nova-C lander, it performed the entire set of burns that it will be expected to execute during the mission.<\/p>\n<p>\u201cBeing able to take that engine and run it that entire time means that you never turn your engine off. So, you never have that fear that it is going to light the next time because it\u2019s lit and it stays lit all the way to the surface,\u201d Martin said. \u201cAnd that\u2019s what makes the technology that we\u2019re flying different than some of our competitors have.\u201d<\/p>\n<figure id=\"attachment_65344\" aria-describedby=\"caption-attachment-65344\" style=\"width: 876px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-65344\" src=\"http:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM-1-Mission-Success-Criteria.jpg\" alt=\"\" width=\"876\" height=\"493\" srcset=\"https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM-1-Mission-Success-Criteria.jpg 876w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM-1-Mission-Success-Criteria-300x169.jpg 300w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM-1-Mission-Success-Criteria-678x381.jpg 678w, https:\/\/spaceflightnow.com\/wp-content\/uploads\/2024\/02\/20240213_IM-1-Mission-Success-Criteria-768x432.jpg 768w\" sizes=\"auto, (max-width: 876px) 100vw, 876px\"><figcaption id=\"caption-attachment-65344\" class=\"wp-caption-text\">An infographic of the flightpath for Intuitive Machines\u2019 Nova-C lander.
