Moon Lander Tipped Sideways on Lunar Surface but ‘Alive and Well’
Table of Contents
The moon lander, affectionately named Odysseus, remains “alive and well,” albeit in an unexpected position, resting on its side following a tense touchdown. This historic event marks the first time a private spacecraft has successfully reached the lunar surface, and the first such achievement by the United States since 1972, according to a statement from the company responsible for the mission, Intuitive Machines.
Analysis conducted by flight engineers revealed that during its final descent, Odysseus likely snagged one of its six landing feet on the lunar surface, causing it to tip over and come to rest sideways, supported by a rock. Despite this unforeseen circumstance, the vehicle appears to be stable near its intended landing site, located close to a crater known as Malapert A, situated in the region of the moon’s south pole, as stated by Stephen Altemus, CEO of Intuitive Machines.
Communication with the lander has been established, with mission control operators actively sending commands to the vehicle. Efforts are underway to obtain the first photographic images from the lunar surface at the landing site.
Initial reports suggested that Odysseus had landed upright, but Altemus clarified that this conclusion was based on pre-landing telemetry data. Despite its sideways orientation, the majority of the NASA science and technology payloads onboard the lander remain accessible for communication, which is deemed favorable by company officials.
However, challenges persist, including limited communication due to two of the spacecraft’s antennae pointing towards the surface. Additionally, the functionality of a solar energy panel is uncertain as it is now facing the wrong direction. Nevertheless, a secondary solar array appears operational, and the spacecraft’s batteries are fully charged.
Mission director Tim Crain praised the flawless performance of the spacecraft, which utilized a propulsion fuel of liquid methane and liquid oxygen for the first time in space. Despite encountering a navigation system issue during its final approach, engineers successfully implemented a workaround, ensuring a successful descent.
Upon touchdown, it took some time to re-establish communication with Odysseus, leaving mission control initially uncertain about the vehicle’s condition and position. However, contact was eventually reestablished, confirming the successful landing.
Crain anticipates that the payloads aboard the lander will operate for approximately nine or ten days before the polar landing site is engulfed in darkness.
Following the announcement of the lander’s tipped position, shares of Intuitive Machines experienced a sharp decline in after-hours trading, erasing gains made during the previous market session.

Scientists identify neutron star born out of supernova seen in 1987
In 1987, a massive star, up to 20 times the mass of our sun, exploded in a neighboring galaxy, emitting a blast so powerful that it remained visible to the naked eye from Earth’s southern hemisphere for weeks. Recently, scientists have achieved a remarkable breakthrough by identifying the aftermath of this supernova – an incredibly dense celestial object known as a neutron star.
Researchers announced on Thursday that two instruments aboard the James Webb Space Telescope (JWST), operating at infrared wavelengths, detected distinctive chemical signatures involving argon and sulfur atoms. These findings provided crucial evidence indicating the presence of a newborn neutron star concealed behind the remnants of the supernova explosion.
Supernova explosions can produce two types of exotic compact objects: black holes or neutron stars. The observations made by the Webb telescope have finally resolved the mystery surrounding the fate of the star that gave rise to this particular supernova event.
“After more than three decades of tracking the supernova and searching for the compact object, it is exhilarating to finally uncover the evidence pointing to the existence of the neutron star, courtesy of JWST,” remarked Claes Fransson, a professor of astrophysics at Stockholm University in Sweden and the lead author of the study published in Science.
Neutron stars are incredibly dense remnants resulting from the explosive demise of a massive star. As Patrick Kavanagh, a lecturer in the department of experimental physics at Maynooth University in Ireland and a co-author of the study, explains, “Neutron stars are immensely dense compact remnants of the explosion of a massive star, comparable to compressing all the mass of the sun into the size of a city. They are so dense that a tablespoon of neutron star can weigh as much as a mountain.”
The supernova, known as Supernova 1987A, occurred approximately 160,000 light years away from Earth in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. For reference, a light year represents the distance that light travels in a year, equivalent to about 5.9 trillion miles (9.5 trillion kilometers). Due to its significant mass, the star had a relatively short lifespan of around 20 million years, much shorter than our sun’s lifespan.
The light emitted by the supernova explosion was visible from Earth on February 24, 1987, just a day after scientists detected a burst of neutrinos – subatomic particles generated in abundance during the collapse of a massive star’s core – emanating from the supernova. This event marked the first instance since 1604 that a supernova had been observable without the aid of telescopes.
Stars with masses at least eight to ten times greater than that of the sun conclude their existence with a supernova, dispersing a significant portion of their material into space following the collapse of their cores. However, they leave behind a remnant. Despite the catastrophic nature of these explosions, they are vital contributors to the creation of chemical elements essential for life, including carbon, oxygen, silicon, and iron.
The nature of the remnant depends on the size of the doomed star and can manifest as either a neutron star or a black hole – an entity so gravitationally intense that not even light can escape its pull.
With Supernova 1987A, the size of the star and the duration of the neutrino burst had suggested that the remnant would likely be a neutron star. However, direct evidence confirming this hypothesis had been lacking until now.
“Direct evidence supporting either of these exotic objects has never been detected so soon after a supernova explosion – until now,” Kavanagh affirmed.
The instruments aboard the Webb telescope detected argon and sulfur atoms that had been ionized, indicating that their outer electrons had been stripped off. Through thorough analysis, the researchers concluded that only ultraviolet and X-ray radiation emitted by a neutron star could have caused these atoms to be ionized in such a manner.
Currently, the researchers are endeavoring to ascertain the specific type of neutron star involved: whether it is a rapidly rotating pulsar with a robust magnetic field or a less active variety with a weaker magnetic field.
This breakthrough represents yet another milestone for the James Webb Space Telescope, which commenced operations in 2022.
Following the explosion, debris comprising dust with a mass exceeding 200,000 times that of Earth formed, rendering the region surrounding the resulting neutron star too opaque for observation using telescopes focused on optical or ultraviolet wavelengths. However, the Webb telescope’s ability to operate in the infrared spectrum circumvented this obstacle.
“In the infrared spectrum, this dust becomes significantly more transparent,” explained Mike Barlow, an astronomer at University College London and a co-author of the study.
