Throughout its lunar journey, Odysseus has outperformed the expectations of the engineers ob the moon mission. The Houston-based private American company Intuitive Machines built and ran the agile robotic lander, which NASA confirmed had been operating and gathering data since it landed and rolled over on the lunar surface on February 22.
At a NASA news event on February 28, Intuitive Machines CEO Steve Altemus said, “What a magnificent job that lander did.” “There is a tonne of science, data, and knowledge. We’re incredibly pleased with that because it’s amazing evidence of how sturdy that little spacecraft is.
The spacecraft was the first American spacecraft to execute a soft landing on the moon in over 50 years, carrying payloads from universities, industry, and NASA (SN: 2/22/24). After spending almost six days on the lunar surface, scientists plan to put Odysseus, also known as Odie, into sleep mode on February 28 since its energy is gradually running low. When the light shines on the lander’s solar panels once more in roughly three weeks, they will attempt to reawaken Odie.
Similar to the mythical hero from the Greek classic The Odyssey, Odysseus, the spaceship, had hardships during its voyage. When the laser range finder on its autonomous landing system failed, engineers had to work quickly to devise a workaround, which required spending two more hours in orbit and rearranging a few backup lasers on a NASA cargo. Odysseus’s landing gear broke during a nerve-wracking descent when it caught on the sloping terrain or maybe a crack. This caused the spaceship to gently topple over on its side.
“Our navigation system landed us with precision, and the shock absorbers took the load,” Altemus stated, notwithstanding the incident. “The landing gear protected the lander upon landing on the surface, doing its job as intended.”
The spacecraft was initially intended to be in operation for roughly a week, however, mission director Tim Crain, chief technology officer of Intuitive Machines, stated that in the best-case scenario, it would stay in operation for nine to ten days at a briefing with reporters on February 23.
Rather, it was anticipated that the lander would run out of power after six days on the moon. Crain stated, “We’re going to tuck Odie in for the cold night of the moon,” at the briefing on February 28. “Once the power system gets back up, we’re going to leave the computers and power system somewhere we can wake it up.”
The primary constraint on Odysseus’s ability to reactivate will be its batteries, as their chemistry-based technology will be unable to withstand the sharp drop in temperature during the lunar night. “We’re sure the solar arrays will energise and send power when the sun comes back up,” Crain stated. “Are the batteries there to receive that power and pass it on?” is the actual query.
About 300 kilometres from the lunar south pole, on the edge of a crater known as Malapert A, is where Odysseus, who is about 4 metres tall and 1.5 metres wide, fell. In the upcoming decades, astronauts participating in NASA’s crewed Artemis programme might land at or close to this location (SN: 12/1/22).
Throughout the voyage, a few of the spacecraft’s numerous cargos have experienced small adventures of their own. For example, a camera constructed by students at Daytona Beach, Florida’s Embry-Riddle Aeronautical University, was intended to separate during descent and snap images as the spacecraft descended. The camera, called EagleCam, was not launched because of landing issues, but Crain stated he and colleagues are preparing it for ejection.
However, photographs from a telescope it sent aboard Odysseus, called ILO-X, have been received by the Kamuela, Hawaii-based International Lunar Observatory Association, a private organisation. The device is meant to be used for scientific views of the Milky Way from the moon and is a forerunner to a larger telescope that the business plans to install at Malapert A in the future. The association attested to ILO-X’s ability to capture photographs taken throughout the trip, which include the Odysseus lander, the sun, and some of the lunar surface. The pictures should be available on February 29.
According to Sue Lederer, a project scientist for NASA’s Commercial Lunar Payload Services at the Johnson Space Centre in Houston, every NASA instrument that Odysseus carried has been sending back valuable data. After solving the spacecraft’s antenna issues that initially impeded full transmission, engineers have been inundated with data.
“We transitioned from essentially a cocktail straw of data to a straw the size of boba tea,” explained Lederer. “We have received more than 15 megabytes of data.” According to her, this will help with comprehending the spacecraft’s touchdown sequence and guide upcoming lunar and Mars missions.
