—Webb Space Telescope: “NASA’s Webb Confirms Its First Exoplanet“

Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter. The research team is led by Kevin Stevenson and Jacob Lustig-Yaeger, both of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.

—ABC News: “Russia Will Launch New Capsule to Return Space Station Crew“

Russia will send up a new capsule next month to bring back three space station crew members whose original ride home was damaged, officials said Wednesday. The two Russians and one American will stay several extra months at the International Space Station as a result of the capsule switch, possibly pushing their mission to close to a year, NASA and Russian space officials told reporters.

—MSN Science Alert: “Massive Volcanic Outburst Detected on Jupiter’s Hellish Moon Io“

In the space around Jupiter, a torus of plasma created and fed by Io’s volcanic emissions grew significantly richer between July and September of last year and persisted until December, showing the moon underwent a spate of volcanic activity that released a huge amount of material. For something that’s just a little bit bigger than Earth’s Moon, Io is an absolute beast of volcanism. It’s bristling with volcanoes, with around 150 of the 400 known volcanoes erupting at any given time, creating vast lakes of molten lava.

—NASA: “Apollo Astronaut Walter Cunningham Dies at 90“

Former astronaut Walter Cunningham, who flew into space on Apollo 7, the first flight with crew in NASA’s Apollo Program, died early Tuesday morning in Houston. He was 90 years old. “Walt Cunningham was a fighter pilot, physicist, and an entrepreneur – but, above all, he was an explorer. On Apollo 7, the first launch of a crewed Apollo mission, Walt and his crewmates made history, paving the way for the Artemis Generation we see today,” said NASA Administrator Bill Nelson. “NASA will always remember his contributions to our nation’s space program and sends our condolences to the Cunningham family.”

—New Atlas: “Curiosity Finds Opal on Mars – a Possible Water Source for Astronauts“

NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water. Opal is formed when water weathers silica-rich rocks, forming a solution that settles into cracks and crevices in the rock. Over time, this solution hardens into a solid lump that can be cloudy and dull or a dazzling display of color. Most supplies come from either Australia or Ethiopia, but now a new source has been discovered – Mars.

—Space.com: “Juno Spacecraft Recovering its Memory After Mind-blowing Jupiter Flyby, NASA Says“

NASA’s Juno probe is continuing to recover its memory at Jupiter after a data disruption interrupted communications between the spacecraft and its operators on Earth following a flyby of the giant planet in December. The Juno spacecraft’s latest flyby of Jupiter, its 47th close pass of the planet, was completed on Dec. 14. But as its operators at NASA’s Jet Propulsion Laboratory were receiving science data from the flyby they found they could no longer directly access the spacecraft’s memory. The team successfully rebooted Juno’s computer and on Dec. 17 they placed the spacecraft into “safe mode” with only essential systems operating as a precaution.

China is aiming to grow cooperation with emerging space nations including Saudi Arabia and the United Arab Emirates. Space was named as one of a number of priority areas for the next three to five years during the first China-Gulf Cooperation Council (GCC) Summit held in Riyadh earlier this month. “China stands ready to work with GCC countries on remote sensing and communications satellite, space utilization, aerospace infrastructure, and the selection and training of astronauts,” according to the text of the keynote speech made by Chinese President Xi Jinping at the summit, Dec. 9. The GCC intergovernmental group comprises Saudi Arabia, the United Arab Emirates, Bahrain, Kuwait, Oman and Qatar.

—Newsweek: “Once-in-a-Lifetime Cosmic Event Could Be Visible to the Naked Eye“

A comet zooming through the solar system could soon be visible to the naked eye from Earth in what will be a once-in-a-lifetime event. And some astronomical predictions indicate that the object may never return to our cosmic neighborhood. C/2022 E3 (ZTF) is currently located around 100 million miles away from Earth and will make a close approach to our planet in early February 2023.

—Atalayar.com: “Europe Runs out of Rockets for Autonomous Access to Space“

Overnight, the European Space Agency (ESA) headed by Austrian Josef Aschbacher has been left without any capacity to position its own satellites in outer space. Neither Aschbacher nor his director of space transport, the Swiss Daniel Neuenschwander, have any space vector model to fulfil their commitments to the European Union to renew the Copernicus constellation and place their Sentinel environmental monitoring satellites in orbit. Much less is ESA in a position to meet the growing global demand for launch services that is knocking on its doors, those of the United States, China and India.

Temperatures in a Russian Soyuz crew ferry ship docked at the International Space Station — a lifeboat for three of the lab’s seven crew members — remain within safe limits despite a dramatic overnight leak in the spacecraft’s cooling system, officials said Thursday. The leak developed around 7:45 p.m. EST Wednesday amid preparations for a planned 6-hour and 40-minute spacewalk by cosmonauts Sergey Prokopyev and Dmitri Petelin to move a radiator from the Rassvet module, where the Soyuz MS-22/68S spacecraft is docked, to the new Nauka laboratory module.

The White House announced the new membership of an advisory group of the National Space Council Dec. 16 with wholesale changes in the roster reflecting a new emphasis on climate change and workforce issues. Vice President Kamala Harris, chair of the National Space Council, announced a roster of 30 members of the Users’ Advisory Committee (UAG), the advisory group that supports the council on various space topics. Their membership on the committee is pending a formal appointment by the NASA administrator, a formality linked to NASA’s role in hosting the UAG.

—Phys.org: “Rubble Pile Asteroids Might be the Best Places to Build Space Habitats“

There has long been a dream of building a massive rotating space station to call home, such as the one featured in “2001: A Space Odyssey,” but the challenges of construction are huge, not to mention the logistics of lifting such large quantities of steel and other materials into space. A rotating station would need to be at least hundreds of feet across to make artificial gravity practical The bigger the better. So engineers have proposed spinning up asteroids as a kind of ready-built station. We would need to dig out the interior, but this would give us materials we could use.

Jeff Bezos’ space company Blue Origin is partnering with Boeing Co and Lockheed Martin Corp to pitch a lunar lander to NASA as the agency seeks to send humans to the moon again, the companies announced on Tuesday. The joint moon lander proposal, led by Blue Origin, marks the companies’ second attempt to win a coveted moon lander contract as NASA seeks more options for getting astronauts to the lunar surface under its multibillion dollar Artemis program.

—Western University: “‘Unexpected’ Space Traveller Defies Theories About Origin of Solar System“

Researchers from Western have shown that a fireball that originated at the edge of the Solar System was likely made of rock, not ice, challenging long-held beliefs about how the Solar System was formed. Just at the edge of our Solar System and halfway to the nearest stars is a collection of icy objects sailing through space, known as the Oort Cloud. Passing stars sometimes nudge these icy travellers towards the Sun, and we see them as comets with long tails. Scientists have yet to observe any objects in the Oort Cloud directly, but everything detected so far coming from its direction has been made of ice. Theoretically, the very basis of understanding our Solar System’s beginnings is built upon the foundation that only icy objects exist in these outer reaches and certainly, nothing made of rock.

—Universe Today: “ESA’s Upcoming Mission Will Tell us if Venus is Still Volcanically Active“

The EnVision mission is ESA’s fifth medium-class mission to Venus. It’s being planned in a partnership between NASA and ESA, and NASA will be providing the synthetic aperture radar instrument, which will map the surface (much as Magellan did). In addition to the two radars, the orbiter will carry spectrometers to study the atmosphere and surface. They will monitor trace gases in the atmosphere and analyze surface composition. The idea is to look for surface changes that might be linked to signs of active volcanism. Along with the VERITAS and DAVINCI missions, EnVision should reveal all we need to know about volcanic activity on Venus.
