—PhysicsWorld: “US Astronomers Slam Cuts to the Chandra X-ray Observatory“

X-ray astronomers in the US have begun a campaign to save the Chandra X-ray Observatory from budget cuts that would effectively end the mission. They assert that the craft, which was launched in 1999, has plenty of life left in it. Cancelling support could, they say, damage scientific efforts to understand the universe and the careers of an emerging generation of X-ray astronomers.

—CNN: “NASA Rethinks Plan to Return Rare Mars Samples to Earth“

“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away,” Nelson said. “Safely landing and collecting the samples, launching a rocket with the samples off another planet — which has never been done before — and safely transporting the samples more than 33 million miles (53 million kilometers) back to Earth is no small task. We need to look outside the box to find a way ahead that is both affordable and returns samples in a reasonable time frame.”

—NASA: “NASA’s TESS Temporarily Pauses Science Observations“

NASA’s TESS (Transiting Exoplanet Survey Satellite) entered into safe mode April 8, temporarily interrupting science observations. The team is investigating the root cause of the safe mode, which occurred during scheduled engineering activities. The satellite itself remains in good health. The team will continue investigating the issue and is in the process of returning TESS to science observations in the coming days.

—ScienceAlert: “NASA Has Finally Identified The Reason Behind Voyager 1’s Gibberish“

For months now, the most distant spacecraft to Earth – Voyager 1 – has been talking gibberish on the interplanetary ‘radio’. The repetitive jumble of 1s and 0s it’s sending back to our planet, 24 billion kilometers (15 billion miles) away, has made no sense to scientists until now. Turns out, officials at NASA just needed to give the oh-so-distant craft a bit of a ‘poke’ to ask it how it was feeling. The system returned a software readout to Earth that scientists have now used to confirm about 3 percent of its memory is corrupted. Which is why turning the FDS on and off didn’t resolve the issue back in November of 2023.

—CBS News: “3 Companies Win NASA Contracts to Develop New Artemis Moon Rover Designs“

Along with funding the commercial development of new rockets, Artemis moon landers and new spacesuits, NASA is pressing ahead with plans to buy an unpressurized moon rover that can carry astronauts, science payloads — or both — across the rugged terrain of the lunar south pole, officials said Wednesday. The agency announced contract awards to three companies to develop competing designs for a Lunar Terrain Vehicle, or LTV, similar in concept to the rovers that carried the last three Apollo crews across the moon’s surface more than 50 years ago.

—NOIRLab: “Construction of Largest Digital Camera Ever Built for Astronomy Completed“

After two decades of work, scientists and engineers at the Department of Energy’s SLAC National Accelerator Laboratory and their collaborators are celebrating the completion of the LSST Camera. Once mounted on Vera C. Observatory’s Simonyi Survey Telescope, the 3200-megapixel camera will help researchers observe our Universe in unprecedented detail. During its ten-year Legacy Survey of Space and Time, the LSST Camera will generate an enormous trove of data on the southern night sky that researchers will mine for new insights into dark energy, dark matter, the changing night sky, the Milky Way and our Solar System.

—Astrobiology: “Mars Express Celebrates 25,000 Orbits“

ESA’s Mars Express recently looped around Mars for the 25,000th time – and the orbiter has captured yet another spectacular view of the Red Planet to mark the occasion. The new high-altitude view was taken by Mars Express’s High Resolution Stereo Camera (HRSC). It features many of Mars’s towering volcanoes and even includes a surprise appearance from the planet’s largest moon, Phobos.

—Daily Mail: “Piece of 5,800lb Battery Pallet Tossed from NASA’s ISS Crashes Through Florida Home – and Nearly Kills Homeowner’s Son“

A piece of metal came crashing through a home in Florida that is believed to be from a 5,800-pound battery pallet discarded by the International Space Station (ISS). Naples homeowner Alejandro Otero was on vacation when he received a call from his son, saying he heard a ‘tremendous sound’ and there were gaping holes in the ceiling and floor – while explaining whatever fell almost hit him. The two-pound, cylinder object has since been recovered by NASA to determine its origin and if found to be space junk, the agency could be liable for damages.

—Reuters: “White House Directs NASA to Create Time Standard for the Moon“

The White House on Tuesday directed NASA to establish a unified standard of time for the moon and other celestial bodies, as the United States aims to set international norms in space amid a growing lunar race among nations and private companies. The head of the White House Office of Science and Technology Policy (OSTP), according to a memo seen by Reuters, instructed the space agency to work with other parts of the U.S. government to devise a plan by the end of 2026 for setting what it called a Coordinated Lunar Time (LTC).

—Euronews: “Photos from NASA’s Curiosity Rover Suggest Mars had More Water for Longer Than Previously Thought“

Scientists say Mars may have had more water and stayed wet for longer than they had previously estimated based on photos from NASA’s Curiosity rover. An international team of researchers led by Imperial College London recently found unusual formations in rock and sediment in unexpected places in the crater. The rocks allow scientists to compare the evolving geology of Mars with Earth.

—U.S. Senate: “Padilla, Butler Urge NASA to Fully Fund Mars Sample Return Program“

Today, U.S. Senators Alex Padilla and Laphonza Butler (both D-Calif.) wrote to NASA Administrator Bill Nelson urging him to allocate the full $650 million necessary to fund the Mars Sample Return (MSR) mission in NASA’s FY24 spending plan. The Senators are issuing the letter following the passage of the FY 2024 appropriations package, which reiterated Congress’ strong commitment to the MSR mission.

—European Space Agency: “Saturn’s Moon Enceladus Top Target for ESA“

A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyses them for hints of life. ESA has started to turn this scene into a reality, devising a mission to investigate an ocean world around either Jupiter or Saturn. But which moon should we choose? What should the mission do exactly? A team of expert scientists has delivered their findings...Aiming for transformational science, considering the characteristics of each moon and future planned missions to Jupiter and Saturn’s ocean worlds, the scientists identified Saturn’s moon Enceladus as the most compelling target, followed by Saturn’s moon Titan and then Jupiter’s moon Europa.

A new spacecraft will at last launch its first crew in May, and a fresh group of NASA astronauts say they’re excited to support it. NASA’s newest astronaut group graduated from basic training on March 5, just in time for the first Boeing Starliner test launch with astronauts, which is now expected in May…When it’s up and running, Starliner will regularly carry astronauts to and from the ISS alongside SpaceX’s Crew Dragon vehicle, which began its own astronaut flights in 2020. The newest astronaut cohort can’t wait to climb on board the Boeing craft.

—Sky & Telescope: “Giant Ancient Volcano Discovered on Mars“

It’s not every day that a giant volcano is discovered hiding in plain sight. By reviewing satellite imagery from many missions, scientists have spotted the remains of a colossal volcano on Mars. The volcano, provisionally named “Noctis Mons,” had been imaged repeatedly since the early 1970s, but extensive erosion had concealed it from view. Researchers have also spotted hints at an adjacent glacier buried underneath the volcanic slopes. Noctis Mons is located near the Martian equator, in the eastern part of the Tharsis volcanic province, sandwiched between the vast canyons of Valles Marineris and the fractured maze-like terrain of Noctis Labyrinthus.

—University of Ottawa: “New Research Suggests that Our Universe has No Dark Matter“

The current theoretical model for the composition of the universe is that it’s made of ‘normal matter,’ ‘dark energy’ and ‘dark matter.’…A University of Ottawa study published today challenges the current model of the universe by showing that, in fact, it has no room for dark matter...This discovery challenges the prevailing understanding of the universe, which suggests that roughly 27% of it is composed of dark matter and less than 5% of ordinary matter, remaining being the dark energy.
