Enigmatic North Korea may attempt to put a satellite in orbit, as early as this week.

As NASA prepares to return astronauts to the Moon with Artemis III, China is ramping up its efforts for a crewed lunar landing, targeting earlier than 2030. Lin Xiqiang, the deputy director of China’s Manned Space Agency announced that the Chinese Lunar Exploration Program (CLEP) is preparing for a “short stay on the lunar surface and human-robotic joint exploration.”

As Artemis II gets ready to launch in November 2024, NASA recently announced it is pursuing contract proposals from private companies for the development of a next-generation Lunar Terrain Vehicle (LTV) to be used for crewed missions starting with Artemis V, which is currently scheduled for 2029. NASA has set a due date for the proposals of July 10, 2023, at 1:30pm Central Time, with the announcement for rewarded contracts to occur in November 2023.

Launched on April 14, 2023, the European Space Agency’s (ESA) Jupiter Icy Moons Explorer (Juice; formerly known as JUICE) spacecraft has finally completed the unfurling of its solar panel arrays and plethora of booms, probes, and antennae while en route to the solar system’s largest planet.

In a recent study published in National Science Review, a team of researchers led by the China University of Geosciences discuss direct evidence of an ancient ocean and its shoreline that existed in the northern hemisphere of Mars during the Hesperian Period, or more than 3 billion years ago. This finding is based on data collected by the China National Space Agency’s (CNSA) Zhurong rover in the Vastitas Borealis Formation (VBF), which lies within southern Utopia Planitia on Mars.

When two black holes collide, they don’t smash into each other the way two stars might. A black hole is an intensely curved region of space that can be described by only its mass, rotation, and electric charge, so two black holes release violent gravitational ripples as merge into a single black hole. The new black hole continues to emit gravitational waves until it settles down into a simple rotating black hole. That settling down period is known as the ring down, and its pattern holds clues to some of the deepest mysteries of gravitational physics.

NASA makes successful rover missions seem mundane. Spirit and Opportunity were wildly successful, and Curiosity and Perseverance would both be considered successes even if they stopped working today. But complex missions don’t succeed without rigorous testing.

The European Space Agency’s latest third generation Meteosat-I 1 weather satellite shows its stuff, with more to come.

New images that combine data from NASA’s Chandra X-ray Observatory and the James Webb Space Telescope (JWST) JWST have just been released! The images feature four iconic astronomical objects, showcasing the capabilities of these observatories by combining light in the visible, infrared, and X-ray wavelengths. These include the NGC 346 star cluster located in the Small Magellanic Cloud (SMC), the NGC 1672 spiral galaxy, the Eagle Nebula (Messier 16, or M16), and the spiral galaxy Messier 74 (aka. the Phantom Galaxy).

In the early days of spaceflight, just getting a satellite into Earth’s orbit was an accomplishment. In our era, landing rovers on other planets and bringing samples home from asteroids is the cutting edge. But the next frontier is rapidly approaching, when astronauts will stay for long periods of time on the Moon and hopefully Mars.

Asteroid mining is slowly but surely coming closer to reality. Many start-ups and governmental agencies alike are getting in on the action. But plenty of tools that would help get this burgeoning industry off the ground are still unavailable. One that would be particularly useful is a list of potential candidate asteroids to visit. While the information has been available in various places, no one has yet combined it into a single, searchable database until now.  

After a two-year hiatus, Virgin Galactic’s SpaceShipTwo VSS Unity resumed flying crew members beyond a 50-mile-high space milestone, marking the end of a years-long flight test program and setting the stage for the start of commercial service as soon as next month.

New images from NASA’s Lunar Reconnaissance Orbiter (LRO) appear to show the crash site where the Japanese Hakuto-R Mission 1 lunar lander impacted the surface of the Moon a month ago.

Have you noticed a lack of gravitational wave announcements the past couple of years? Well, now it is time to get ready for an onslaught, as the Laser Interferometric Gravitational-Wave Observatory (LIGO) starts a new 20-month observation run today, May 24th after a 3-year hiatus.

They’re affectionately known as “pillownauts,” volunteers who commit to spending weeks in bed to advance research into astronaut health. While bedridden, the pillownauts will lie with their heads tilted at 6° below the horizontal with their feet up to increase blood flow to their heads. They also perform work-related tasks, are subject to regular medical exams, and take their meals, showers, and bathroom breaks, all while remaining in bed. The purpose of this research is to simulate the effects of weightlessness on the human body, including muscle atrophy, bone density loss, and cognitive effects.

Uranus takes 84 years to orbit the Sun, and so that last time that planet’s north polar region was pointed at Earth, radio telescope technology was in its infancy.

After almost seventy years of study, astronomers are still fascinated by active galactic nuclei (AGN), otherwise known as quasi-stellar objects (or “quasars.”) These are the result of supermassive black holes (SMBHs) at the center of massive galaxies, which cause gas and dust to fall in around them and form accretion disks. The material in these disks is accelerated to close to the speed of light, causing it to release tremendous amounts of radiation in the visible, radio, infrared, ultraviolet, gamma-ray, and X-ray wavelengths. In fact, quasars are so bright that they temporarily outshine every star in their host galaxy’s disk combined.

Jupiter’s moon Io is the most volcanic world in the Solar System, with over 400 volcanoes. Some of them eject plumes as high as 500 km (300 mi) above the surface. Its surface is almost entirely shaped by all this volcanic activity, with large regions covered by silicates, sulphur, and sulphur dioxide brought up from the moon’s interior. The intense volcanic activity has created over 100 mountains, and some of them are taller than Mt. Everest.

The European Space Agency has been hosting a series of robotic teleoperation experiments where an astronaut abroad the ISS controls a robot back on the ground. We’ve previously reported on some of their successes. Now it’s time for the next round of experiments, with one individual astronaut on the ISS controlling four separate robots to perform a task back on Earth.

Is it a multimedia art project? Or a rehearsal for alien contact? Let’s call it both: Researchers specializing in the search for extraterrestrial intelligence, or SETI, are working with a media artist to stage the receipt of an interstellar message — and a global effort to decode the message.

Remember the huge Tonga eruption in the South Pacific in January 2022? This underwater volcano sent tons of ash into the air. It also blew 146 teragrams of water into our atmosphere and the effect of the explosion reached space. It also made life very difficult for people on Tonga, wiping out their communications and sending tsunamis across the South Pacific.
