—German Aerospace Center: “PLATO Mission to Launch in Late 2026 Onboard Ariane 6“

On 29 January 2025, the European Space Agency (ESA)’s Director of Science, Carole Mundell; ESA’s Director of Space Transportation, Toni Tolker-Nielsen; and Arianespace’s Chief Commercial Officer, Steven Rutgers, signed the launch contract for the ESA PLATO science mission...PLATO stands for PLAnetary Transits and Oscillations of stars…PLATO’s goal is to detect Earth-like planets that orbit Sun-like stars in the Milky Way and may even have conditions suitable for life.

—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.

Here are some recent stories of interest related to the upcoming Intuitive Machines’ launch to the Moon.

—CNN: “A Tiny Spacecraft is Poised to Launch on an Unprecedented Deep-space Mission. The CEO Behind it is ‘Terrified’“

His venture may seem far out, but asteroid mining CEO Matt Gialich has no illusions. The engineer cofounded the bold California startup AstroForge in 2022 with the aim of hunting for precious metals in space, and he is all too aware that success is not guaranteed…The probe is set to lift off aboard a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida on February 26. AstroForge’s spacecraft will ride alongside Athena, a lunar lander developed by the startup Intuitive Machines, until it breaks off on its own.

—Caltech: “NASA’s Lunar Trailblazer is Launching to the Moon’“

NASA’s Lunar Trailblazer mission is led by Caltech’s Bethany Ehlmann, professor of planetary science and the Allen V. C. Davis and Lenabelle Davis Leadership Chair and director of the Keck Institute for Space Studies, and the mission is operated by IPAC at Caltech. The Lunar Trailblazer small satellite, or smallsat, will orbit the Moon to understand the nature of water on the Moon’s surface, providing maps to guide future robotic and human explorers. Prior missions have seen hints of ice and other forms of water that could be used in a variety of ways, from purifying it for human use, to processing it for fuel and breathable oxygen for future human Moon landings.

—Fox News: “NASA Will Test Cell Phone Service on the Moon in Latest Mission’“

NASA and Intuitive Machines are gearing up for a Wednesday evening liftoff, and one of the payloads will test a moon-based cell network. Researchers with Nokia Bell Labs Solutions Research developed the network and say it’s the same tool that we use here on Earth when we pick up our phones and make a call. But they had to make a cell tower much smaller so it could fit in a rocket and land on the moon.

—European Space Agency: “Solar Orbiter Ready for Close Encounter with Venus’“

The European Space Agency (ESA) is ready to guide the ESA/NASA Solar Orbiter spacecraft through its closest encounter with Venus so far. Today’s flyby will be the first to significantly ‘tilt’ the spacecraft’s orbit and allow it to see the Sun’s polar regions, which cannot be seen from Earth. Studying the Sun’s poles will improve our understanding of solar activity, space weather, and the Sun-Earth connection.

—UC Irvine News: “UC Irvine Astronomers Gauge Livability of Exoplanets Orbiting White Dwarf Stars’“

Among the roughly 10 billion white dwarf stars in the Milky Way galaxy, a greater number than previously expected could provide a stellar environment hospitable to life-supporting exoplanets, according to astronomers at the University of California, Irvine. In a paper published recently in The Astrophysical Journal, a research team led by Aomawa Shields, UC Irvine associate professor of physics and astronomy, share the results of a study comparing the climates of exoplanets at two different stars. One is a hypothetical white dwarf that’s passed through much of its life cycle and is on a slow path to stellar death. The other subject is Kepler-62, a “main sequence” star at a similar phase in its evolution as our sun.

—Uppsala University: “Mission Accomplished for Space Telescope Gaia’“

The space telescope Gaia has created the largest three-dimensional map of the Milky Way ever. On January 15, 2025, Gaia shut down after 11 years in space. But the research on data Gaia collected will continue for many years to come. Gaia is a space telescope onboard a satellite that has orbited the sun for 11 years. With the help of astrometry, which is a technique to measure the positions, distances and movements of stars and other heavenly bodies, Gaia has been able to measure distances and luminosities for up to 2 billion stars, which is about 1% of all stars in the Milky Way.

—Vatican News: “Vatican Astronomer Releases ‘A Jesuit’s Guide to the Stars’“

Br Guy Consolmagno, the director of the Vatican Observatory, has published a new book entitled A Jesuit’s Guide to the Stars. Published on the 4th February, the book charts the long history of Jesuit engagement with astronomy. As Consolmagno notes in the book’s introduction, this is a story which has its origin in the very earliest days of the Society of Jesus. The founder of the Jesuit order, St Ignatius of Loyola, says in his autobiography (which, somewhat confusingly, is written in the third person) that “the greatest consolation that he received . . . was from gazing at the sky and stars, and this he did often, and for quite a long time.”

—LiveScience: “Astronomers Discover ‘Quipu’, the Single Largest Structure in the Known Universe“

Astronomers have discovered what may be the largest-scale structure in the known universe — a group of galaxy clusters and clusters of galaxy clusters that spans roughly 1.3 billion light-years across and contains a mind-boggling 200 quadrillion solar masses. The newfound structure is dubbed Quipu after an Incan system of counting and storing numbers using knots on cords.

—Astrobiology: “A Large Number Of Exocomets Have Been Discovered“

CfA astronomers and its Submillimeter Array were critical for identifying a cache of belts where comets may reside outside our Solar System. For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are orbiting. This result reveals regions around 74 stars spanning a wide range of ages – from those recently formed to others billions of years old – showing how comets play a role in the formation of stars and planetary systems.

Here are some recent stories of interest related to changes at NASA.

—Science: “DEI Order Grounds NASA Program to Link Undergraduates with Mission Scientists“

At NASA, officials are moving quickly to comply with President Donald Trump’s executive order directing agencies to cease funding for diversity, equity, and inclusion (DEI) programs. NASA has already informed researchers supported by one high-profile program for undergraduate students that several of the agency’s spacecraft contractors will no longer take part in the program, following the agency’s guidance. And NASA has warned the researchers that it is likely to kill grants that have already been awarded.

—Space News: “NASA Pauses Work of Science Groups, Citing Trump Executive Orders“

NASA has directed a set of science committees to pause their work, citing recent Trump administration executive orders, a move that canceled one meeting and put planning for others on hold. NASA Headquarters sent memos Jan. 31 to the leaders of several committees, known as “analysis groups” or “assessment groups,” that provide input to the agency’s astrophysics and planetary science divisions. The memo said NASA needed to determine if the groups’ activities complied with new executive orders.

—Orlando Sentinel: “Despite DEI Demise, NASA Still Touts Goal to Land 1st Woman, 1st Person of Color on Moon“

NASA continues to highlight goals of landing the first woman and first person of color on the lunar surface even amid the agency’s recent shutdown of diversity, equity and inclusion programs — also known as DEI — under executive orders from President Trump. “With NASA’s Artemis campaign, we are exploring the moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars,” reads the Artemis mission statement on NASA’s website. “We will collaborate with commercial and international partners and establish the first long-term presence on the moon. NASA will land the first woman, first person of color, and first international partner astronaut on the moon using innovative technologies to explore more of the lunar surface than ever before.” The announcement NASA would send the first woman to the moon came under Trump’s first presidency.
