NASA launched two rockets from Alaska this week to learn more about the electrical “circuitry” within auroras, the colorful light shows that occur when solar wind collides with Earth’s atmosphere. The missions saw two suborbital sounding rockets launch from the Poker Flat Research Range near Fairbanks, Alaska loaded with scientific equipment that will fly into the atmosphere for a short period of time to gather data. The destination for the rockets in both missions was the northern lights, or aurora borealis.

—Physics World “India Announces Three New Telescopes in the Himalayan Desert“

India has unveiled plans to build two new optical-infrared telescopes and a dedicated solar telescope in the Himalayan desert region of Ladakh. The three new facilities, expected to cost INR 35bn (about £284m), were announced by the Indian finance minister Nirmala Sitharaman on 1 February.

—SETI Institute: “Saturn’s Moon Titan Could Have Formed in a Merger of Two Old Moons“

Recent research suggests that Saturn’s bright rings and its largest moon, Titan, may have both originated in collisions among its moons. While Cassini’s 13-year mission expanded our understanding of Saturn, the discoveries of its young rings and Titan’s rapidly shifting orbit raised new questions. Now, a study led by SETI Institute scientist Matija Ćuk proposes an explanation linking the formation of the moons and rings, centering on the possibility that Titan is the product of a moon merger.

—ARSTecnica: “Russia is About to do the Most Russia Thing Ever with its Next Space Station“

For several years now, in discussing plans for its human spaceflight program beyond the International Space Station, Russian officials would proudly bring up the Russian Orbital Station, or ROS…Oleg Orlov, director of the Institute of Biomedical Problems of the Russian Academy of Sciences, said ROS will no longer be composed of entirely new modules. Rather, its core will be the Russian segment of the International Space Station. “The Scientific and Technical Council of Roscosmos supported this proposal and approved the deployment of a Russian orbital station as part of the Russian segment of the ISS,” Orlov reportedly said.

—Daily Galaxy: “NASA Faces Major Setback: One Mars Orbiter Lost and Another Is Expected to Shut Down Soon!“

NASA is losing critical communication links with its Mars missions. After recently losing contact with the MAVEN spacecraft, the agency faces the impending loss of the Mars Odyssey orbiter, which has been circling the Red Planet for over two decades. As both orbiters approach the end of their operational lifespans, NASA will soon have to find ways to maintain data relay capabilities for its rovers and other missions on the fourth planet.

—NASA/JPL: “NASA Study Suggests Saturn’s Moon Titan May Not Have Global Ocean“

A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data suggests a more complicated picture: Titan’s interior is more likely composed of ice, with layers of slush and small pockets of warm water that form near its rocky core. Led by researchers at NASA’s Jet Propulsion Laboratory in Southern California and published in the journal Nature on Wednesday, the new study could have implications for scientists’ understanding of Titan and other icy moons throughout our solar system.

—SpaceNews.com: “Key Antenna in NASA’s Deep Space Network Damaged“

One of the largest antennas in NASA’s Deep Space Network was damaged in September and may be out of service for an extended period, further straining the system. NASA’s Jet Propulsion Laboratory confirmed Nov. 10 that the 70-meter antenna at the Deep Space Network (DSN) site in Goldstone, California, has been offline since Sept. 16, with no timetable for its return to service.

—University of Geneva: “Dark Matter Does Not Defy Gravity, Study Suggests“

Does dark matter follow the same laws as ordinary matter? The mystery of this invisible and hypothetical component of our universe—which neither emits nor reflects light—remains unsolved. A team involving members from the University of Geneva (UNIGE) set out to determine whether, on a cosmological scale, this matter behaves like ordinary matter or whether other forces come into play. Their findings, published in Nature Communications, suggest a similar behavior, while leaving open the possibility of an as-yet-unknown interaction. This breakthrough sheds a little more light on the properties of this elusive matter, which is five times more abundant than ordinary matter.

—University of Oxford: “Saturn’s Icy Moon May Host a Stable Ocean Fit for Life, New Study Finds“

A new study led by researchers from Oxford University and Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus’ north pole, overturning previous assumptions that heat loss was confined to its active south pole. This finding confirms that the icy moon is emitting far more heat than would be expected if it were simply a passive body, strengthening the case that it could support life.

—The Economic Times: “NASA Confirms Earth Has a Second Moon, And It Will Stay With Us Until 2083“

Earth has received a new cosmic partner, a small asteroid designated as 2025 PN7. NASA confirmed this week that the object, initially found by the University of Hawaii, qualifies as a “quasi-moon” , an uncommon type of celestial body that moves almost similarly in sync with Earth. While not a real moon, it has a similar orbit surrounding the Sun, seeming to shadow our planet as it travels through space. Researchers estimate the asteroid measures 18 to 36 meters wide, approximately the height of a small building, making it small by cosmic standards but noteworthy for Earth’s extended neighborhood.

—Sky&Telescope: “New Study Identifies Organic Molecules Spewing from Saturn’s Icy Moon Enceladus“

Twenty years after the Cassini spacecraft discovered an ocean under the icy surface of Saturn’s moon Enceladus, a new study of previously collected data hints at a much better chance for habitability. The change comes from recording how a plume of ice grains hit Cassini just minutes after it erupted from the moon. The close encounter exposed organic compounds not previously seen on Enceladus.

—Utrecht University: “Mysterious Gullies on Mars Appear to Have Been Dug, But by Whom or What?“

Did life really exist on Mars after all? Unfortunately, there is no conclusive evidence for this yet. Nevertheless, it would seem that some form of life was the driving force behind the mysterious Martian dune gullies. Earth scientist Dr Lonneke Roelofs from Utrecht University has investigated how these gullies were formed. In a test setup, she observed that blocks of CO2 ice ‘dug’ these gullies in a unique way. “It felt like I was watching the sandworms in the film Dune.”

—Physics World: “NASA Criticized Over its Management of $3.3bn Dragonfly Mission to Titan“

An internal audit has slammed NASA over its handling of the Dragonfly mission to Saturn’s largest moon, Titan. The drone-like rotorcraft, which is designed to land on and gather samples from Titan, has been hit by a two-year delay, with costs surging by $1bn to $3.3bn. NASA now envisions a launch date of July 2028 with Dragonfly arriving at Titan in 2034.

—USAToday: “Do Rockets Still Launch During a Government Shutdown? How NASA Could Feel the Effects“

NASA is far from immune to the effects of a looming government shutdown if congressional leaders fail to reach an agreement before midnight Oct. 1 to prevent one. At stake for the U.S. space agency if the federal government grinds to a halt? The progress of many of its science missions and access to its public outreach arm. NASA’s contingency plan for a shutdown, outlined in a guide from 2018, emphasizes that only “activities which are necessary to prevent harm to life or property” would be exempt from ceasing operations during a shutdown.

—Earth Sky: “‘Invisible’ Asteroids Near Venus: A New Danger to Earth?“

Astronomers across the globe are dedicated to identifying the near-Earth asteroids that could one day impact our planet. But there might be a group of potentially dangerous nearby asteroids that have remained invisible to astronomers so far. On September 24, 2025, an international team of researchers at the São Paulo State University (UNESP) in Brazil said that a group of asteroids sharing Venus’ orbit could have remained undetected so far due to their location in the sky. And they could pose a threat to Earth within a few thousand years.
