We’re getting better views of interstellar Comet 3I/ATLAS, as it makes its speedy passage through the inner solar system. This week, astronomers at the Gemini North observatory located on Mauna Kea in Hawai’i turned the facility’s enormous 8.1-meter telescope on the object, with amazing results.

Astronomers using the Subaru Telescope have discovered a new object in the Kuiper Belt, beyond the orbit of Pluto. Designated 2023 KQ14, it's categorized as a "sednoid," with an extremely eccentric orbit - only the 4th ever discovered. Its orbit is much different from other sednoids, which challenges the hypothesis that Planet Nine could be aligning their orbits. It was found at 72 AU, but its path takes it all the way out to 438 AU, taking almost 4,000 years to complete one orbit.

There’s a good reason for sky watchers to set their alarms this coming Sunday morning. If skies are clear, viewers across most of North America will have a rare chance to see the waning crescent Moon occult (pass in front of) the Pleiades open star cluster.

There are plenty of engineering challenges facing space exploration missions, most of which are specific to their missions objectives. However, there are some that are more universal, especially regarding electronics. A new paper primarily written by a group of American students temporarily studying at Escuela Tecnica Superior de Ingenieria in Madrid, attempts to lay out plans to tackle several of those challenges for a variety of mission architectures.

Astronomers have found a young star bathing a planet in intense X-ray radiation, wearing it away at a rapid rate. The planet is Jupiter-sized and orbits its red dwarf star at a fifth the distance from Mercury to the Sun. It's only 8 million years old, and researchers estimate that within a billion years, it will lose its entire atmosphere, going from 17 Earth masses down to just 2 Earth masses. They estimate that it's losing an Earth's atmosphere worth of mass every 200 years.

The long-serving space telescope saw the third interloper to enter the solar system from beyond its limits late on Monday morning (July 21).

Media are invited to hear from NASA’s SpaceX Crew-10 during a news conference beginning at 10:40 a.m. EDT, Friday, July 25, from the International Space Station.

NASA astronauts Anne McClain and Nichole Ayers, JAXA (Japan Aerospace Exploration Agency) astronaut Takuya Onishi, and Roscosmos cosmonaut Kirill Peskov will discuss their upcoming return to Earth on the agency’s YouTube channel.

Media interested in participating must contact the newsroom at NASA’s Johnson Space Center in Houston no later than 5 p.m., Thursday, July 24, at 281-483-5111 or jsccommu@mail.nasa.gov. To ask questions, media must dial into the news conference no later than 10 minutes prior to the start of the call. A copy of NASA’s media accreditation policy is online.

Crew-10 joined the Expedition 72 crew when arriving to the station in March. Throughout Expedition 72 and into Expedition 73, the crew aboard the space station contributed to hundreds of experiments, including testing expanded capabilities of existing hardware for pharmaceutical production in space, investigating how cells sense gravity, which is an important aspect of space biology, and examining the effects of microgravity on protein yields in microalgae, a potential source for life support, fuel, and food on long-duration missions.

The crew will depart the space station after the arrival of Crew-11 and a handover period. Ahead of Crew-10’s return, mission teams will review weather conditions at the splashdown sites off the coast of California prior to departure from station.

The mission is part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.
