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.

Space Stories: Earth Gives Extra Juice, Starship’s First Orbit, Starliner Returns, and the Missing Moon

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.

Space Quote: A New Space Telescope is Being Planned

“With our Webb and Roman space telescopes, we set a cadence of launching premiere-class missions in both halves of the decade. We’re going to keep that up and kick off the next decade with PRIMA, as part of a pipeline that will consistently have missions of this caliber ready to go.”

–Statement by Shawn Domagal-Goldman, director of the Astrophysics Division at NASA Headquarters, regarding the planned $1.2 billion PRobe far-Infrared Mission for Astrophysics (PRIMA) space telescope. The plan is to launch the space telescope in 2033 to conduct a five-year mission. The main mission of the space telescope will pertain to exoplanet origins, galaxy growth and black hole evolution. It is encouraging to hear about NASA planning these future missions with all the talk of program cuts from the White House. It is probably presumed that the Congress will keep the funding coming.

Study Findings: New Lunar Crater Reveals Extensive Distal Regolith Modification

Sciences Advances abstract of study findings:

A new ∼222-meter-diameter impact crater formed on the Moon in spring 2024. Discovered in repeat Lunar Reconnaissance Orbiter Camera images, it provides a unique opportunity to study surface modification by a pristine impact, prior to subsequent fading. Nighttime temperatures measured by the Diviner instrument reveal an ∼7-kilometer-wide cold spot that is 8 to 9 kelvin cooler than its surroundings, consistent with decompaction of the upper centimeters to decimeters of regolith. We investigate all newly formed craters >20 meters identified to date and find that all craters larger than ∼30 meters produce detectable cold spots, indicating that cold spot formation is a common consequence of fresh lunar impacts. Cold spot temperature anomaly increases with crater size, implying deeper regolith modification around larger craters. This scaling suggests that the cumulative effect of cold spot formation may modify the shallow regolith at rates comparable to impact gardening by primary craters, making them a substantial driver of regolith evolution on regolith-covered airless bodies.

—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.
