—Phys.org: “Russia Will Use International Space Station ‘Until 2028’”

Russia said Wednesday it planned to use the International Space Station until 2028, an apparent reversal of an earlier announcement to quit the orbiting laboratory after 2024. On Wednesday, the head of Russian space agency Roscosmos, Yuri Borisov, said Moscow’s participation in the international space project had been extended. “By the decision of the government, the operation of the International Space Station has been extended until 2028,” Borisov told President Vladimir Putin during a televised meeting, referring to the Russian segment.

—SpaceNews.com: “Czech Republic signs Artemis Accords”

The Czech Republic became the 24th country to sign the Artemis Accords May 3, growing Europe’s presence in the U.S.-led agreement. In a brief ceremony at NASA Headquarters, Jan Lipavský, minister of foreign affairs for the Czech Republic, formally signed the accords in the presence of officials from NASA and the U.S. State Department. Representatives of several other countries who previously signed the Artemis Accords also attended…Neither U.S. nor Czech officials announced specific plans to cooperate on the Artemis lunar exploration campaign as a result of signing the accords, but suggested the signing opened the door for future discussions.

China will attempt to collect the first samples from the far side of the moon next year with its Chang’e 6 mission. The complex, four-spacecraft mission will launch on a Long March 5 rocket from Wenchang in May 2024, according to Wu Yanhua, chief designer of China’s Deep Space Exploration Major Project, speaking at a deep-space exploration conference on April 25 in the Chinese city of Hefei.

—Astronomy.com: “Japanese Lunar Lander Loses Contact Moments Before Touchdown”

The Japanese start-up ispace attempted to become the first private company to successfully soft-land a commercial spacecraft on the Moon today (Tuesday, April 25). However, it now appears that the landing attempt — like several other such attempts in recent years — has failed…Ispace currently plans to attempt at least two more lunar landings over the next few years, applying lessons learned during today’s landing attempt to increase their odds of success.

—Phys.com: “Scientists Discover Rare Element in Exoplanet’s Atmosphere”

The rare metal terbium has been found in an exoplanet’s atmosphere for the first time. The researchers at Lund University in Sweden have also developed a new method for analyzing exoplanets, making it possible to study them in more detail…”Detecting heavy elements in the atmospheres of ultra-hot exoplanets is another step towards learning how the atmospheres of planets work. The better we get to know these planets, the greater chance we have of finding Earth 2.0 in the future,” concludes Nicholas Borsato.

—NASA: “NASA InSight Study Provides Clearest Look Ever at Martian Core”

While NASA retired its InSight Mars lander in December, the trove of data from its seismometer will be pored over for decades to come. By looking at seismic waves the instrument detected from a pair of temblors in 2021, scientists have been able to deduce that Mars’ liquid iron core is smaller and denser than previously thought.

—PetaPixel: “Webb Captures Star-Forming Galactic Merger Brighter Than 1 Trillion Suns’”

NASA’s James Webb Space Telescope has captured a stunning “smash-up” of two spiral galaxies. Collectively called Arp 220, the collision of the pair of galaxies has facilitated massive star formation. Arp 220 is located within the constellation Serpens, about 250 million light-years from Earth. Arp 220 gets its namesake because it is the 220th object in Hallton Art’s Atlas of Peculiar Galaxies. Arp 220 is “peculiar” because it’s an ultra-luminous infrared galaxy (ULIRG), and the nearest ULIRG to Earth.

—Phys.org: “NASA’s TESS Celebrates Fifth Year Scanning the Sky for New Worlds’”

Now in its fifth year in space, NASA’s TESS (Transiting Exoplanet Survey Satellite) remains a rousing success. TESS’s cameras have mapped more than 93% of the entire sky, discovered 329 new worlds and thousands more candidates, and provided new insights into a wide array of cosmic phenomena, from stellar pulsations and exploding stars to supermassive black holes.

—NASA: “NASA’s Ingenuity Mars Helicopter Completes 50th Flight’”

NASA’s Ingenuity Mars Helicopter has completed its 50th flight on Mars. The first aircraft on another world reached the half-century mark on April 13, traveling over 1,057.09 feet (322.2 meters) in 145.7 seconds. The helicopter also achieved a new altitude record of 59 feet (18 meters) before alighting near the half-mile-wide (800-meter-wide) “Belva Crater.”

—Gizmodo.com: “New NASA Official Took Her Oath of Office on Carl Sagan’s ‘Pale Blue Dot’”

When Dr. Makenzie Lystrup was sworn in as the new director of NASA’s Goddard Space Flight Center last week, she didn’t take her oath of office on the Bible or the U.S. Constitution, but rather on a tome revered by space enthusiasts everywhere: Carl Sagan’s Pale Blue Dot. The book, published in 1994, is named after an iconic image of Earth, snapped by the Voyager I probe, that depicts the planet as a small speck smothered by the emptiness of space. That photo inspired astronomer Carl Sagan to write: “Look again at that dot. That’s here. That’s home. That’s us.” For many, the book serves as a reminder of humanity’s place in the universe and the need to preserve our home planet, which makes it similar to holy scripture for a newly appointed NASA director.

—Time: “In Five Years, China Will Start Building a Lunar Base With Bricks Made From Moon Soil“

China plans to start building a lunar base in about five years, kicking off with bricks made of moon soil, according to scientists with ties to the project, the South China Morning Post reported. Ding Lieyun, a top scientist at Huazhong University of Science and Technology, told local media that the first brick would be made from moon soil during the Chang’e 8 mission around 2028.

—AFAR: “NASA Teams With NYC Museum on New Immersive Outer Space Exhibit“

With its blazing city lights, New York is one of the worst places to go stargazing. But space aficionados will want to visit lower Manhattan this spring—dark skies or not—thanks to a new digital art exhibit created with participation from NASA and CNES (the French space agency) that opened April 7 at Hall des Lumières, the city’s first permanent immersive art center. An earlier iteration of this show premiered at Hall des Lumières’ sister museum in Paris, Atelier des Lumières, in 2021. Destination Cosmos: The Immersive Space Experiencewill run for eight weeks through June 4, 2023, at Hall des Lumières, which opened in 2022 in the former Emigrant Savings Bank across from City Hall.

—Washington University in St. Louis: “Scientists Share ‘Comprehensive’ Map of Volcanoes on Venus — all 85,000 of Them“

Byrne and Hahn’s new study includes detailed analyses of where volcanoes are, where and how they’re clustered, and how their spatial distributions compare with geophysical properties of the planet such as crustal thickness. Taken together, this work provides the most comprehensive understanding of Venus’ volcanic properties — and perhaps of any world’s volcanism so far. That’s because, although we know a great deal about the volcanoes on Earth that are on land, there are still likely a great many yet to be discovered under the oceans. Lacking oceans of its own, Venus’ entire surface can be viewed with Magellan radar imagery.

—CNN: “Repeating Radio Signal Leads Astronomers to an Earth-Size Exoplanet“

Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may have a magnetic field and perhaps even an atmosphere…Scientists noticed strong radio waves coming from the star YZ Ceti and the rocky exoplanet that orbits it, called YZ Ceti b, during observations using the Karl G. Jansky Very Large Array of telescopes in New Mexico. The researchers believe the radio signal was created by interactions between the planet’s magnetic field and the star.

—ScienceNews: “Baby Jupiter Glowed so Brightly it Might have Desiccated its Moon“

A young, ultrabright Jupiter may have desiccated its now hellish moon Io. The planet’s bygone brilliance could have also vaporized water on Europa and Ganymede, planetary scientist Carver Bierson reported March 17 at the Lunar and Planetary Science Conference. If true, the findings could help researchers narrow the search for icy exomoons by eliminating unlikely orbits. Jupiter is among the brightest specks in our night sky. But past studies have indicated that during its infancy, Jupiter was far more luminous. “About 10 thousand times more luminous,” said Bierson, of Arizona State University in Tempe.
