NASA is projecting spending nearly $1 billion on a tug to deorbit the International Space Station at the end of the decade to provide redundancy for safely disposing of the station. NASA released additional details March 13 about its fiscal year 2024 budget proposal. An outline of the proposal, published by the White House March 9, requested $27.2 billion for the agency, a 7.1% increase from 2023 that roughly keeps pace with inflation.
Kazakh authorities have impounded the property of Russia’s main operator of spacecraft launching sites in Baikonur (Baiqonyr) in the Central Asian nation’s southern region of Qyzylorda…According to the media outlet, the decision was made due to the Russian state company’s debt of 13.5 billion tenges ($29.7 million) to the Baiterek Kazakh-Russian joint venture for work related to estimating ecological damage caused by Souyz-5 rockets.
NASA and the Department of Energy (DOE) are working together to develop a science instrument that will survive the harsh and unforgiving environment of the lunar surface at night on the far side of the Moon to attempt first-of-its-kind measurements of the Dark Ages of the Universe. The instrument, named the Lunar Surface Electromagnetics Experiment – Night (LuSEE-Night), is a collaboration between DOE’s Brookhaven National Laboratory, the DOE Office of Science, UC Berkeley’s Space Sciences Laboratory, and NASA’s Science Mission Directorate.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected gaseous water in the planet-forming disc around the star V883 Orionis. This water carries a chemical signature that explains the journey of water from star-forming gas clouds to planets, and supports the idea that water on Earth is even older than our Sun.
“We can now trace the origins of water in our Solar System to before the formation of the Sun,” says John J. Tobin, an astronomer at the National Radio Astronomy Observatory, USA and lead author of the study published today in Nature.
Astronomers have discovered the closest black hole to Earth, the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1,600 light-years away, offers an intriguing target of study to advance understanding of the evolution of binary systems.
What time is it on the moon? Since the dawn of the space age, the answer has been: It depends. For decades, lunar missions have operated on the time of the country that launched them. But with several lunar explorations heading for the launchpad, the European Space Agency has deemed the current system unsustainable. The solution, the agency said last week, is a lunar time zone.
Elon Musk’s rocket company SpaceX was ready to try again at sending NASA’s next long-duration crew of the International Space Station to orbit on Thursday, about 72 hours after a first attempt was scrubbed due to a clogged filter in the launch system. Two NASA astronauts will be joined by a Russian cosmonaut and an astronaut from the United Arab Emirates for a six-month science mission made up of experiments ranging from human cell growth in space to controlling combustible materials in microgravity.
NASA will launch Israel’s first space telescope mission, the Ultraviolet Transient Astronomy Satellite (ULTRASAT). ULTRASAT, an ultraviolet observatory with a large field of view, will investigate the secrets of short-duration events in the universe, such as supernova explosions and mergers of neutron stars. Led by the Israel Space Agency and Weizmann Institute of Science, ULTRASAT is planned for launch into geostationary orbit around Earth in early 2026. In addition to providing the launch service, NASA will also participate in the mission’s science program.
Approximately 20,000 organic molecules composed of carbon, hydrogen, nitrogen, oxygen, or sulfur were found in samples returned to Earth from the asteroid Ryugu by the Japan Aerospace Exploration Agency’s Hayabusa2 mission, according to new work published in two Science papers from an international team that included Carnegie’s George Cody, Jens Barosch, and Larry Nittler. Named after a Japanese folktale, Ryugu is a near-Earth object, half a mile across, shaped kind of like a spinning top that orbits the Sun every 16 months. Hayabusa2 was the first mission to bring material back to Earth from a primitive asteroid, offering unique insight into the building blocks from which our Solar System was formed and the possible origin of organic material that contributed to Earth’s habitability.
Images from NASA’s Mars Reconnaissance Orbiter reveal that China’s Zhurong rover remains stationary on the Red Planet as China remains silent on the status of its spacecraft. The High Resolution Imaging Science Experiment (HiRISE) camera aboard the Mars Reconnaissance Orbiter (MRO) captured images of the rover on March 11, 2022, a second on Sept. 8, 2022 and finally Feb. 7, 2023. The images were published Feb. 21 by the HiRISE Operations Center.
Astronomers have discovered what appear to be massive galaxies dating back to within 600 million years of the big bang, suggesting the early universe may have had a stellar fast-track that produced these “monsters.” While the new James Webb Space Telescope has spotted even older galaxies, dating to within a mere 300 million years of the beginning of the universe, it’s the size and maturity of these six apparent mega-galaxies that stunned scientists. They reported their findings Wednesday in the journal Nature.
A decades-old Soviet era piece of space junk has crashed back to Earth after over 40 years in orbit, improbably crash landing back in its home country, Russia. The abandoned Soviet Vostok-2M Blok E rocket stage, weighing more than 3,000 pounds, “made an uncontrolled reentry over Novaya Zemlya at 1016 UTC Feb 20 after 42.7 years in orbit,” tweeted Jonathan McDowell, an astrophysicist and group leader at the Chandra X-ray Center Science Data Systems.
Searching through existing data spanning 9 billion years, a team of researchers led by scientists at University of Hawaiʻi at Mānoa has uncovered the first evidence of “cosmological coupling” –a newly predicted phenomenon in Einstein’s theory of gravity, possible only when black holes are placed inside an evolving universe.
UH Mānoa astrophysicists Duncan Farrah, a faculty member at the Institute for Astronomy and the Department of Physics and Astronomy, and Kevin Croker, a professor of physics and astronomy led this ambitious study, combining Hawaiʻi’s expertise in galaxy evolution and gravity theory with the observation and analysis experience of researchers across nine countries to provide the first insight into what might exist inside real black holes.
Chemists have discovered a new form of ice, and their work may have major consequences for our understanding of the outer solar system. We usually encounter three forms of water on the surface of Earth: solid, liquid, and vapor. On our planet, solid ice mainly comes in one variety, where water molecules arrange themselves into an orderly and repeated crystalline structure. But scientists have discovered 19 other varieties of water-ice that may appear throughout the universe.
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), Chinese astronomers have detected a new galaxy, which received designation FAST J0139+4328. The newfound galaxy is isolated, has a relatively low stellar mass, and is dominated by dark matter. The discovery was detailed in a paper published February 6 on the arXiv pre-print server.
