A SpaceX spacecraft carrying four international astronauts is on a pioneering journey circling Earth over its poles after launching Monday night from Florida…Fram2 follows in the footsteps of other commercial spaceflight ventures, including Inspiration4 and Polaris Dawn – two missions also bankrolled and led by billionaire Jared Isaacman. In fact, the Fram2 crew is now traveling on the same Dragon spacecraft that the Polaris Dawn crew rode to orbit in September for a five-day mission in which they completed a historic spacewalk.

—South China Morning Post: “China in Bid to Challenge SpaceX by Deploying Maglev Rocket Launch Pad by 2028“

In a bid to disrupt the United States’ long-held dominance in space exploration, China is quietly advancing a radical new rocket launch system – powered not by roaring engines but by electromagnetic force – that could propel satellites into orbit with unprecedented speed and efficiency. At the heart of the ambitious project is Galactic Energy, a private aerospace company that plans to debut the world’s first electromagnetic rocket launch pad by 2028, a project that could redraw the competitive lines of the global space industry.

—Space Telescope Science Institute: “20-Year Hubble Study of Uranus Yields New Atmospheric Insights“

Halfway through its fourth decade, Hubble’s long life has proven invaluable for studying the atmosphere of the mysterious ice giant Uranus. By repeatedly training Hubble on the distant cyan planet over the course of 20 years, researchers chronicled a two-decade story of seasonal changes. These astronomers have gained new understanding of the atmospheric dynamics of Uranus, which can serve as a proxy for studying exoplanets of similar size and composition.

—Ars Technica: “After a Spacecraft was Damaged en route to Launch, NASA Says it Won’t Launch“

Three weeks ago, NASA revealed that a shipping container protecting a Cygnus spacecraft sustained “damage” while traveling to the launch site in Florida. Built by Northrop Grumman, Cygnus is one of two Western spacecraft currently capable of delivering food, water, experiments, and other supplies to the International Space Station. This particular Cygnus mission, NG-22, had been scheduled for June. As part of its statement in early March, the space agency said it was evaluating the NG-22 Cygnus cargo supply mission along with Northrop.

—Intelligent Computing: “AI Reshapes How We Observe the Stars“

AI tools are transforming how we observe the world around us—and even the stars beyond. Recently, an international team proved that deep learning techniques and large language models can help astronomers classify stars with high accuracy and efficiency. Their study, “Deep Learning and Methods Based on Large Language Models Applied to Stellar Light Curve Classification,” was published Feb. 26 in Intelligent Computing.

—CNN: “Toxic Dust on Mars Would Present Serious Hazard for Astronauts“

Toxic dust on Mars would make a future mission to the red planet extremely hazardous for astronauts and require significant countermeasures, new research suggests. Substances such as silica, gypsum, perchlorates and nanophase iron oxides contained in Martian dust could have life-threatening effects on members of a potential Mars mission, according to a study published in the journal GeoHealth last month.

Here are some recent stories of interest related to exoplanets.

—Webbtelescope.org: “NASA’s Webb Images Young, Giant Exoplanets, Detects Carbon Dioxide“

The first planet outside our solar system was discovered in the 1990’s, but it wasn’t until more than a decade later astronomers actually obtained a direct image of one. It’s extremely difficult to image an exoplanet, as stars in other planetary systems can be thousands of times brighter and bigger than their planets. NASA’s James Webb Space Telescope is equipped with a highly sensitive coronagraph, a tiny mask that blocks the light of the star, allowing Webb to image exoplanets. Webb’s new images of two iconic systems, HR 8799 and 51 Eridani, and their planets have stunned researchers, and provided additional information into the chemical make-up of the young gas giants.

—ABC News: “Several Planets Found Orbiting Star Less Than 6 light-years Away“

Astronomers have confirmed the existence of four planets orbiting a star less than 6 light-years away with help from some of the world’s most powerful telescopes. Research published in October 2024 revealed that one planet was rotating around Barnard’s Star, the second-closest single star system to Earth. But a combination of telescopes all over the world confirmed the presence of four small exoplanets, according to a study published last week in The Astrophysical Journal Letters.

—Universe Today: “Astronomers Think They’ve Found a Reliable Biosignature. But There’s a Catch“

The search for life has become one of the holy grails of science. With the increasing number of exoplanet discoveries, astronomers are hunting for a chemical that can only be present in the atmosphere of a planet with life! A new paper suggests that methyl halides, which contain one carbon and three hydrogen atoms, may just do the trick. Here on Earth they are produced by bacteria, algae, fungi and some plants but not by any abiotic, non biological processes. There is a hitch, detecting these chemicals is beyond the reach of current telescopes.

The work NASA conducts in space leads to ongoing innovations benefiting people on Earth. Some of these latest technologies, which have been successfully transferred from NASA to the commercial sector, are featured in the latest edition of Spinoff 2025 publication now available online. The publication features more than 40 commercial infusions of NASA technologies, including research originated at NASA’s Glenn Research Center in Cleveland.

—Cleveland.com: “NASA Urged to Move Headquarters to Ohio as D.C. Lease Expires“

When the National Aeronautics and Space Administration‘s lease on its current Washington, D.C. headquarters expires in 2028, Ohio members of Congress want NASA to move its headquarters to Ohio. In a Tuesday letter to Vice President JD Vance and President Donald Trump’s nominee to be NASA Administrator, Jared Isaacman, Ohio Congress members argue that bringing the headquarters of the nearly 18,000 employee agency to their state would align with broader government efforts to decentralize federal agencies and reinvigorate parts of the country outside Washington.

—USA Today: “Moon King: Astronomers Discover 128 New Moons Orbiting Saturn. Here’s What We Know.“

Astronomers have discovered 128 new moons orbiting Saturn, further solidifying the planet as the “moon king” of our solar system. Astronomers from Taiwan, Canada, France and the U.S. announced the discovery on Tuesday. The findings push Saturn’s moon count to 274, towering over the previous record-holder Jupiter, which has 95 moons. The recent discovery points to what astronomers have speculated for decades, that Saturn’s rings were caused by a massive collision about 100 million years ago, researcher Mike Alexandersen, an astronomer at the Center of Astrophysics, told USA TODAY. A collision of such size could explain the small moons that orbit Saturn.

—ScienceNews: “The Universe’s First Supernovas Probably Produced Water“

The first generation of stars in the universe could have produced significant amounts of water upon their deaths, just 100 million to 200 million years after the Big Bang. Signatures of water have previously been observed some 780 million years after the Big Bang. But now, computer simulations suggest that this essential condition for life existed far earlier than astronomers thought, researchers report March 3 in Nature Astronomy.

—Phys.org: “New Dwarf Galaxy Discovered in the Halo of Andromeda Galaxy“

An international team of astronomers reports the discovery of a new dwarf galaxy, which they have named Pegasus VII. The newfound galaxy, which lies about 2.4 million light years away, was identified in the Ultraviolet Near-Infrared Optical Northern Survey (UNIONS). The discovery was detailed in a research paper published Feb. 13 on the arXiv preprint server. Dwarf galaxies are low-luminosity and low-mass stellar systems, usually containing a few billion stars. Their formation and activity are thought to be heavily influenced by interactions with larger galaxies.
