NASA's brand-new Lunar Trailblazer probe suffers glitch on way to the moon
NASA's Lunar Trailblazer probe could be in trouble.
Lunar Trailblazer launched atop a SpaceX Falcon 9 on Feb. 26 alongside Intuitive Machine's Athena moon lander on the IM-2 mission. The 11.5-foot (3.5-meter), 440-pound (200-kilogram) probe was designed to orbit low over the lunar surface to hunt for and map where water might be found in permanently shadowed regions on the moon. While its launch went smoothly, things do not appear to be going well for the spacecraft, according to a NASA update.
Lunar Trailblazer powered up and began transmitting data after launch, but its operators began noticing power issues and subsequently lost communication with the probe some 12 hours after launch. Mission operators at Caltech and the Jet Propulsion Laboratory were able to reestablish contact with the spacecraft hours later, but are still "working with NASA ground stations to reestablish telemetry and commanding to better assess the power system issues and develop potential solutions," NASA wrote in the update.
Lunar Trailblazer was built by Lockheed Martin and carries two sophisticated instruments to help it hunt for lunar water. One, the Lunar Thermal Mapper (LTM), was designed to map the surface temperature of the moon using infrared light, which could help it map mineral distribution on the lunar surface.
Another instrument aboard the probe, the High-resolution Volatiles and Minerals Moon Mapper (HVM3), built by NASA's Jet Propulsion Laboratory, was designed to measure how much sunlight reflects off the surface of the moon to help it hunt for the chemical "fingerprints" of any water hiding on the lunar surface.
Finding water on the moon is a high priority for NASA as the agency works to establish a sustainable human presence there through its Artemis program. Recent moon-mapping missions have found evidence that water exists in permanently shadowed craters near the lunar south pole, the same region where NASA plans to land astronauts with its Artemis 3 mission.

It remains uncertain how much water might be found there, but scientists hope that it could be used to support a human presence on the moon or even be used to produce resources such as rocket fuel.
Another probe that launched alongside Lunar Trailblazer appears to be in trouble. Astroforge, a private company that hopes to one day mine asteroids for precious resources, launched its Odin probe on the same rocket in order to study asteroid 2022 OB5 ahead of a follow-up mission that will land there.
Odin has yet to phone home, and mission controllers "don't fully understand the state of the vehicle," Astroforge CEO Matthew Gialich posted on X on Friday (Feb. 28).

Astronomers spot 'interstellar object' speeding through solar system
An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed. The object -- likely a comet -- was first detected in data collected between by the Asteroid Terrestrial-impact Last Alert System, or ATLAS -- an asteroid impact early warning system in Rio Hurtado, Chile, funded by NASA, the space agency announced on Tuesday. Properties such as a marginal coma and short tail indicate signs of cometary activity, according to the Minor Planet Center. Numerous telescopes have reported additional observations since the object was first reported, NASA said. Observations from three different ATLAS telescopes around the world -- as well as the Zwicky Transient Facility at the Palomar Observatory in San Diego County, California -- dating back to June 14 were gathered and provided data that supports the existence of the comet, according to a NASA update released Wednesday. It appears to be originating from interstellar space, arriving from the direction of the constellation Sagittarius, and is currently about 420 million miles from Earth, according to NASA. The comet poses no threat to Earth and will remain at a distance of at least 150 million miles, astronomers said. It is estimated to reach its closest approach to the sun around Oct. 30, where it will cross at about 130 million miles away, just inside the orbit of Mars, according to NASA. The object, dubbed "A11pl3Z" or "3I/ATLAS," spans approximately 25 miles, Josep Trigo-Rodriguez, as astrophysicist at the Institute of Space Sciences near Barcelona, Spain, told The Associated Press. It's traveling at a speed of about 152,000 mph and approaching the inner solar system from the bar of the Milky Way, Live Science reported. Its trajectory suggests it did not originate in this solar system, according to This is only the third time in history that an interstellar object entering the inner solar system has been recorded. A cigar-shaped interstellar object called " Oumuamua," the Hawaiian word for "scout," was detected in 2017. And in 2019, an object named " 21/Borisov" -- a comet that likely strayed from another star system -- was located. Astronomers will continue to investigate the size and physical properties of the comet through September, after which it will pass too close to the sun to remain visible, NASA said.

NASA discovers third interstellar comet

Sprecher/UPI | License Photo July 3 (UPI) -- NASA discovered the third interstellar comet through a survey telescope in Rio Hurtado, Chile. The interstellar comet first observed on Tuesday by NASA's Asteroid Terrestrial-impact Alert System telescope, or ATLAS, has been officially named 3I/ATLAS. A series of "pre-discovery" observations dating back to June 14 from three ATLAS Telescopes globally and the Zwicky Transient Facility in California's Palomar Observatory have since been collected, along with new observations from several telescopes since the initial report. "If confirmed, it will be the third known interstellar object from outside our solar system that we have discovered," Dr. Mark Norris, a senior lecturer in astronomy at the University of Central Lancashire, told The Guardian. Dr. Paul Chodas, director of the Center for Near Earth Object Studies at NASA's Jet Propulsion Laboratory in California, told The New York Times there is "no uncertainty" that the comet is from interstellar space, noting speeds that indicate it could not have originated in our solar system. "If you trace its orbit backward, it seems to be coming from the center of the galaxy, more or less," Chodas said. "It definitely came from another solar system. We don't know which one." The comet will reach its closest approach to the Sun around Oct. 30, but it shows no threat to Earth as it will remain at least 150 million miles away. It is currently about 416 million miles from the Sun. In December, the comet is expected to reappear on the other side of the Sun. The comet's size and physical attributes are being investigated. It is expected to remain visible to ground-based telescopes through September. Jake Foster, a Royal Observatory Greenwich astronomer, said: "At the moment, the comet is not expected to be visible to the naked eye, but it should be visible through a reasonably sized amateur telescope in late 2025 and early 2026. As it is studied more over the coming weeks, we'll get a better idea of just how visible it will realistically be." In 2017 Oumunamua traveled through the solar system as the first interstellar object. In 2019, the second interstellar comet, Borisov passed by.

NASA Reveals First-Ever Full Image of Peanut-Shaped Asteroid Donaldjohanson
Scientists with NASA's Lucy mission are finally wrapping up the process of refining the data gathered by the spacecraft's April 20 encounter with Donaldjohanson, an asteroid in our solar system's main asteroid belt. And it's, uh, as peanut-shaped as we first saw it. Earlier this year, Lucy's Long Range Reconnaissance Imager snapped an image of Donaldjohansson while quickly swooping past it, at a distance of about 600 miles (960 kilometers), with the smallest visible features measuring around 130 feet (40 meters) across—an impressive close-up, considering the overall scale of anything we observe in space. Regrettably, the Sun's position behind Lucy reduced the contrast of the asteroid's smaller details. But the close visit is invaluable nevertheless, as it's allowing scientists to carefully comb over the details of its surface after adjusting for the brightness. 'Asteroid Donaldjohanson has strikingly complicated geology,' said Hal Levison, Lucy's principal investigator, in an earlier press release about the asteroid. Donaldjohansson likely got its lumpy shape from a cosmic collision between two smaller objects around 150 million years ago. It's a relatively common shape among smaller asteroids in the solar system, so what we learn from Donaldjohanson could inform our understanding of many other cosmic objects. 'As we study the complex structures in detail, they will reveal important information about the building blocks and collisional processes that formed the planets in our Solar System,' Levison added in the same release. Donaldjohansson is not the main objective of the Lucy mission, whose itinerary is set for the eight Trojan asteroids that share Jupiter's orbit around the Sun. Still, Lucy's Donaldjohanson encounter—and the November 2023 flyby of asteroid Dinkinesh—is an excellent 'dress rehearsal' for Lucy as it continues its journey toward the cooler, outer regions of the solar system, according to NASA's Erin Morton in a statement earlier this week. Lucy's next milestone is set to occur in August 2027, when the spacecraft will finally start to explore the Jupiter Trojan asteroids in earnest—starting with Eurybates, a carbonaceous asteroid so big that it has its own satellite, Queta.
