—LiveScience: “NASA’s Swift Observatory Ends 22-year Mission to Study the Most Powerful Explosions Since the Big Bang“

A pioneering NASA space telescope is no more. In sad news for Swifties everywhere, the Neil Gehrels Swift Observatory has officially ended its mission after more than 20 years of tracking the most powerful explosions in the universe since the Big Bang. According to a NASA announcement, the Swift team shut down the telescope’s science operations Tuesday (Oct. 20) after the observatory fell too low in its orbit to continue taking reliable measurements of the cosmos. In the coming weeks, Swift will drop even further, eventually passing a point of no return and taking a fiery plunge through Earth’s atmosphere.

—EuroNews: “Europe Weighs €10bn Plan to Launch Its Own Astronauts Ahead of Rome Space Summit“

Europe wants to stop depending on others to send its own astronauts into space. The next key date for deciding how to do that is 15 December in Rome, when the member countries of the European Space Agency (ESA) will meet to discuss the future of space exploration. On the table are multi-billion-euro investments, new technologies and one strategic issue: ensuring that Europe can reach Earth orbit with its own means, without relying exclusively on services provided by foreign companies. The summit, officially the Intermediate Ministerial Meeting 2026, comes at a time of transformation in the sector. Member states will have to assess proposals to strengthen Europe’s role in low Earth orbit, prepare for the post-International Space Station era and build the continent’s presence on the Moon, while also looking towards Mars. The aim is not to abandon international cooperation, but to take part in it with greater autonomy

—South China Morning Post: “Chinese Astronomers Find Real 3-body System. It Is Not What Liu Cixin Thinks“

In author and computer engineer Liu Cixin’s science fiction hit The Three-Body Problem, three suns throw a doomed world into chaos. Chinese astronomers say they have found a real three-star system that is far better behaved. Using FAST, the world’s biggest single-dish radio telescope in southwestern China, the researchers found two dead stars and a “living” one locked in a steady cosmic dance about 7,000 light years from Earth. One of the dead stars is a pulsar that spins more than 300 times a second, about as fast as the blades of a kitchen blender. It whirls around its partner, a white dwarf – the dim, burnt-out core of a smaller star – every eight days.

A new ISS crew was launched from Cape Canaveral at 11:10 a.m. EDT Thursday, October 1, 2026 . Crew-13, consisting of NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency (CSA) astronaut Joshua Kutryk, and Roscosmos cosmonaut Sergey Teteryatnikov. The ride to the space station was scheduled to be about 8 hours. The SpaceX Dragon capsule carrying the crew safely docked with the ISS at 9:19 p.m. EDT.

The new crew will replace Crew‑12 consisting of NASA astronauts Jessica Meir and Jack Hathaway, European Space Agency astronaut Sophie Adenot, and Roscosmos cosmonaut Andrey Fedyaev. These four crew members will be returning to Earth as soon as Monday, weather permitting.

Here are some recent space-related stories of interest.

—European Space Agency: “Successful Earth Flyby Improves Juice’s Course to Jupiter”

The European Space Agency’s Jupiter Icy Moons Explorer (Juice) skimmed the very outer edge of Earth’s atmosphere on 28 September, using the gravity of our home planet to alter its route to Jupiter using very little fuel. The flyby deflected Juice by an angle of 20° compared to its pre-flyby path and increased its velocity by 3.5 km/s. In the four weeks before the flyby, spacecraft operators only had to give Juice one tiny nudge (out of six opportunities set aside) to put it on exactly the right approach trajectory to make the most of Earth’s gravity. They have been tracking the spacecraft extra carefully since 17 August, and will continue to do so until 10 October.

—Fox Business News: “SpaceX Launches Starship Into Orbit for First Time Ever But Cuts Mission Short“

SpaceX’s massive Starship rocket blasted off from Texas Monday morning on its most ambitious test flight yet, aiming for a roughly 10-hour mission that would have sent the spacecraft around Earth six times, though the company ultimately decided to end the flight earlier than planned…The launch marks Starship’s 14th test flight and its first attempt to reach orbit, a major step beyond previous suborbital missions that ended with splashdowns about an hour after liftoff.

—CBS News: “NASA Plans Unpiloted Starliner Test Flight After Astronauts Got Stuck at Space Station in 2024“

NASA is working with Boeing to launch an unpiloted Starliner capsule in the December-to-January time frame to test upgrades and improvements ordered in the wake of a 2024 mission that suffered multiple propulsion system failures, stranding two astronauts on the space station for more than nine months. If the unpiloted test flight goes well, NASA and Boeing hope to launch a piloted Starliner flight in the mid-2028 time frame, officials said Monday, incorporating redesigned propulsion system valves, more robust subsystems and other modifications expected to prevent the sort of failures that occurred in 2024. Veteran astronaut Warren “Woody” Hoburg will command the mission.

—Sky & Telescope: “Did Venus Swallow Its Moon?“

It’s a question that has perplexed planetary astronomers for decades: Why does Venus — so similar in size to Earth and not all that far from Earth’s orbit — have no moon, while our planet has such a relatively large one? Earth’s Moon likely formed after a massive collision early in solar system history. But according to calculations, Venus should have been even more likely than Earth to have experienced such a catastrophic crash during its formative years. Yet today it has no moon at all. Now, a series of simulations published in the September 20th Astrophysical Journal, have demonstrated that Venus might once have had a moon — but the planet’s relative proximity to the Sun and its massive atmosphere both created conditions under which no moon could have survived. If there ever was a moon, it would have disintegrated and fallen back to the surface long ago.

Here are some recent space-related stories of interest.

—Spaceflight Now: “Russian Progress cargo ship arrives at International Space Station”

An unpiloted Russian Progress cargo ship arrived at the International Space Station Saturday carrying supplies and equipment for the orbiting outpost. The Progress M-25 docked at the space-facing port of Russia’s Poisk module at 9:44 a.m. EDT (1344 UTC). It circled the station before making its final approach using the automated Kurs rendezvous system. Russian cosmonauts Pyotr Dubrov and Anna Kikina were standing by to take manual control of the approach using remote controls, but everything went smoothly as the craft closed in, 260 miles above the Black Sea. A series of hooks inside the docking mechanism were driven closed to complete the docking operation.

—Science Daily: “Astronomers Just Found the Youngest Known Planet Ever“

Astronomers have confirmed the youngest known planet yet, a world less than 1 million years old that is still surrounded by the gas and dust from which it formed. The planet, called Elias 2-24 b, was identified using observations preserved in NASA-funded archives. It is still orbiting within its young star’s dusty disk, giving scientists a rare opportunity to study planet formation while it is still happening.

—Radio France Internationale: “Europe Weighs the Cost of Sending Its Own Astronauts into Space“

French President Emmanuel Macron wants Europe to develop its own way of sending astronauts into space within a decade. Europe already builds rockets and satellites and sends astronauts to the International Space Station – but it still relies on American spacecraft to get them there. As the global space sector expands, the question is whether Europe should invest in closing that gap, and what it would take to do so.

Space Quote: Yanks Yank Venus Support from Europeans

Posted on by onespaceman2000

“At the moment, we are finalizing our agreement with NASA, but it is looking like they are not able to provide the radar…So that is why we are going full steam ahead with the European solution.”

–Statement by Anne Grete Straume-Lindner, the European Space Agency’s (ESA) project scientist for the Venus mission called Envision, regarding expected cuts in NASA support for the planned Venus mapping mission. Proposed NASA cuts may also impact other ESA missions, including the New Athena observatory, which would take over for NASA’s Chandra X-ray Observatory (also continually on the chopping block) and the Laser Interferometer Space Antenna (LISA) observatory designed to study gravitational waves.
