NASA and SpaceX are looking to undock the Crew-8 mission vehicle from the ISS on October 13, 3:05AM Eastern time. Crew-8's astronauts were originally scheduled to start making their way back to Earth on October 7, but since their spacecraft is going to splash down off the coast of Florida, NASA and SpaceX had decided to push it back "due to weather conditions and potential impacts from Hurricane Milton." They will hold another briefing on the situation on October 11 and could delay the mission's return further for the safety of everyone involved.
The Crew-8 mission launched on March 4 this year with four members: NASA astronauts Matthew Dominick, Michael Barratt and Jeanette Epps, as well as Roscosmos cosmonaut, Alexander Grebenkin. They conducted several experiments while on the International Space Station, such as sequencing the DNA of any antibiotic-resistant organism they could find on the ISS to look into how they adapted to the conditions out there. They also studied human brain organoids created with stem cells to look into Parkinson's disease and into how extended spaceflight affects the human brain. They printed human tissues, studied how microgravity affects drug manufacturing and worked with an Astrobee robot. NASA will most likely cover their flight back on a livestream.
While Crew-8 has yet to leave the space station, SpaceX's Crew-9 mission astronauts have been on board since September 29. That mission only flew with two crew members, because it will be coming back home with NASA astronauts Butch Wilmore and Suni Williams who originally flew to the ISS on the Boeing Starliner. NASA said Wilmore and Williams have already tried on and tested their SpaceX Intravehicular Activity spacesuits and have completed all the work required to fly back to Earth with the Crew-9 vehicle.

I'd be cautious with your software updates if you’ve got a Galaxy phone with a 2019 vintage. An update rolling out from Samsung is reportedly bricking devices from the Galaxy S10 and Galaxy Note 10 series of phones. 9to5Google reported some users had the same issue with Galaxy M51 and A90 models. The Galaxy S10 and Galaxy S10+ are five years old, running Android 12 and circling an age where they may not support updates.
Affected devices were apparently trapped in a bootloop and could not fully turn back on. Don’t factory reset your device, though, as you’ll lose data.
Was this a dark plot to force you to buy a new Galaxy foldable? No. Samsung has now pulled the update and shared a newer version (2.2.03.1) without the issue — make sure you check that update number.
The lawsuit comes barely a month after the state enacted the law.
Texas Attorney General Ken Paxton has filed a lawsuit against TikTok, claiming the company violated a new child privacy law in the state. It’ll be the first test of Texas’ Securing Children Online Through Parental Empowerment (SCOPE) Act. It requires social media platforms to verify the ages of younger users and offer parental control features, including the ability for parents to opt their children out of data collection.
Paxton alleges TikTok’s existing parental control features are insufficient, lacking “parental tools that allow them to control or limit most of a known minor’s privacy and account settings.”
The update will triple the length to three minutes.
Starting on October 15, YouTube is increasing Shorts video limits from one to three minutes. For reference, TikTok, arguably its biggest competitor, has allowed users to share 10-minute videos for over two years. The company is working on letting you pull clips from across YouTube through the Shorts camera and make remix clips. If Shorts aren’t your thing, it will also be easier to skip them as YouTube is introducing a tool to show fewer Shorts, although this is only temporary.
The James Webb Space Telescope has captured a supernova three times, at three different periods during its explosion, in one image. The image could help scientists better understand how fast the universe is expanding. One image, above, captures a streak of light with three distinct dots that appear brighter than the rest of it. As Dr Brenda Frye from the University of Arizona explained, those dots correspond to an exploding white dwarf star. It is also gravitationally lensed — there's a cluster of galaxies between here and the star, which bent the supernova’s light into multiple images.
The James Webb Space Telescope's Near-Infrared Camera (NIRCam) captured a curious sight in a region 3.6 billion light-years away from Earth: A supernova that appears three times, at three different periods during its explosion, in one image. More importantly, this image could help scientists better understand how fast the universe is expanding.
A team of researchers chose to observe the galaxy cluster PLCK G165.7+67.0, also known as G165, for its high star rate formation that also leads to higher supernova rates. One image, which you can see above, captures what looks to be a streak of light with three distinct dots that appear brighter than the rest of it. As Dr. Brenda Frye from the University of Arizona explained, those dots correspond to an exploding white dwarf star. It is also gravitationally lensed — that is, there's a cluster of galaxies between us and the star that served as a lens, bending the supernova's light into multiple images. Frye likened it to a trifold mirror that shows a different image of the person sitting in front of it. To note, it is the most distant Type Ia supernova, which is a supernova that occurs in a binary system, observed to date.
Because of that cluster of galaxies in front of the supernova, light from the explosion travelled three different paths, each with a different length. That means the Webb telescope was able to capture different periods of its explosion in one image: Early into the event, mid-way through and near the end of it. Trifold supernova images are special, Frye said, because the "time delays, supernova distance, and gravitational lensing properties yield a value for the Hubble constant or H0 (pronounced H-naught)."
NASA describes the Hubble constant as the number that characterizes the present-day expansion rate of the universe, which, in turn, could tell us more about the universe's age and history. Scientists have yet to agree on its exact value, and the team is hoping that this supernova image could provide some clarity. "The supernova was named SN H0pe since it gives astronomers hope to better understand the universe's changing expansion rate," Frye said.
Wendy Freedman from the University of Chicago led a team in 2001 that found a value of 72. Other teams put the Hubble constant between 69.8 and 74 kilometers per second per megaparsec. Meanwhile, this team reported a value of 75.4, plus 8.1 or minus 5.5. "Our team’s results are impactful: The Hubble constant value matches other measurements in the local universe, and is somewhat in tension with values obtained when the universe was young," Frye said. The supernova and the Hubble constant value derived from it need for be explored further, however, and the team expects future observations to "improve on the uncertainties" for a more accurate computation.

The Polaris Dawn crew safely returned to Earth early Sunday morning, bringing the historic privately funded mission to a close. The Dragon capsule carrying the mission’s four astronauts — Jared Isaacman, Scott “Kidd” Poteet, Sarah Gillis and Anna Menon — splashed down in the Gulf of Mexico around 3:30AM ET.
On Thursday, Isaacman and Gillis completed the first commercial spacewalk, each taking a turn to exit the craft and perform a series of spacesuit mobility tests. And with this mission, Gillis and Menon have now traveled farther from Earth than any women before. Polaris reached a peak altitude of about 870 miles, which is also the farthest any humans have ventured since the Apollo program.
The crew also performed a number of science experiments, and was able to complete a 40-minute video call to Earth and send files in a major test for Starlink’s space communications capabilities. That included a video recorded during the mission of Gillis, an engineer and violinist, playing the violin in space. “A new era of commercial spaceflight dawns, with much more to come,” Polaris posted on X Sunday morning.

NASA confirmed on Friday that it’s developing a new lunar time system for the Moon. The White House published a policy memo in April, directing NASA to create the new standard by 2026. Over five months later (government time, y’all), the space agency’s confirmation states it will work with “U.S. government stakeholders, partners, and international standards organizations” to establish a Coordinated Lunar Time (LTC).
To understand why the Moon needs its own time zone, look no further than Einstein. His theories of relativity say that because time changes relative to speed and gravity, time moves slightly faster on our celestial neighbor (because of its weaker gravity). So, an Earth clock on the Moon would gain about 56 microseconds a day — enough to throw off calculations that could put future missions requiring precision in danger.
“For something traveling at the speed of light, 56 microseconds is enough time to travel the distance of approximately 168 football fields,” said Cheryl Gramling, NASA timing and standards leader, in a press release. “If someone is orbiting the Moon, an observer on Earth who isn’t compensating for the effects of relativity over a day would think that the orbiting astronaut is approximately 168 football fields away from where the astronaut really is.”
NASA
April’s White House memo directed NASA to work with the Departments of Commerce, Defense, State and Transportation to plot the course for LTC’s introduction by the end of 2026. Global stakeholders, particularly Artemis Accords signees, will play a role. Established in 2020, the agreements include a growing collection of 43 countries committed to norms expected to be honored in space. Notably, China and Russia have refused to join.
NASA’s Space Communication and Navigation (SCaN) program will lead the initiative. One of LTC’s goals is to be scalable to other celestial bodies in the future, including Mars. The time standard will be determined by a weighted average of atomic clocks on the Moon, although their locations are still up for debate. Such a weighted average is similar to how scientists calculate Earth’s Coordinated Universal Time (UTC).
NASA plans to send crewed missions back to the Moon through its Artemis program. Artemis 2, scheduled for September 2025, plans to send four people on a pass around the Moon. A year later, Artemis 3 aims to land astronauts near the Moon’s South Pole.

A concerning report from the National Academies of Sciences, Engineering and Medicine (NASEM) expresses some serious concerns about the future of America’s space exploration agency.
The NASEM report was written by a panel of aerospace experts and lays out what it sees as a possible "hollow future” for the National Aeronautics and Space Administration (NASA). It addresses issues of underfunding due to “declining long-term national emphasis on aeronautics and civil space,” an assertion that NASA itself is aware of and agrees with. The report also notes that NASA’s problems extend far beyond having enough funding to carry out its missions and operations.
Some of the report’s “core findings” suggest areas of concern that could affect the space agency’s future. These include a focus on “short-term measures without adequate consideration for longer-term needs and implications,” reliance on “milestone-based purchase-of-service contracts” and inefficiency due to “slow and cumbersome business operations.” The report also raised concerns about the current generation of talent being siphoned off by private aerospace companies, and the next generation of engineers not receiving an adequate foundation of knowledge due to our underfunded public school systems. Finally the report states bluntly that NASA’s infrastructure “is already well beyond its design life.”
These and other issues could lead to even more serious problems. Norman Augustine, a former Lockheed Martin chief executive and the report’s lead author, told The Washington Post that reliance on the private sector could further erode NASA's workforce, reducing its role to one of oversight instead of problem-solving.
Congress could allocate more funds to NASA to address these concerns but that’s not likely since it’s constantly struggling to prevent government shutdowns. Instead, Augustine says NASA could focus on prioritizing its efforts on more strategic goals and initiatives.

A SpaceX Dragon capsule carrying the four private astronauts of the Polaris Dawn mission has launched from the Kennedy Space Center in Florida in the early hours of September 10 after a few weeks of delays. The mission was scheduled to lift off at the end of August but was postponed first due to technical issues, then because of poor weather conditions forecasted for the crew’s return. On board are Jared Isaacman — the billionaire who funded the mission — retired Air Force Lieutenant Colonel Scott “Kidd” Poteet, and SpaceX engineers Sarah Gillis and Anna Menon. They’ll attempt several firsts during the five-day flight, including the first-ever commercial spacewalk.
That attempt will also mark the first spacewalk from a Dragon capsule. Among Polaris Dawn's other goals is to send its crew farther than anyone has traveled since the Apollo program, targeting an altitude of about 870 miles from Earth. The journey will take the capsule and its crew briefly into the Van Allen radiation belt.
The @PolarisProgram’s Polaris Dawn mission will be the first crew to perform a spacewalk from Dragon, fly higher in Earth’s orbit than anyone since the Apollo program, test laser-based @Starlink communications, and conduct research to help provide insight on human health during… pic.twitter.com/RW387QWShY
Polaris Dawn is meant to be the first of three human spaceflight missions under Isaacman’s Polaris Program. Its crew will put SpaceX’s new Extravehicular Activity space suit to its most important test yet, as they’ll all wear it for protection against the vacuum of space when the Dragon’s doors open for the spacewalk. The spacewalk will take place at an elliptical orbit roughly 435 miles above Earth’s surface, and two crew members will leave the capsule.

Boeing's Starliner capsule has undocked from the ISS at 6:04PM Eastern time on September 6 and has safely and gently landed at White Sands Space Harbor in New Mexico at 12:01AM on September 7. Calypso, as the capsule is called, didn't have a crew onboard despite flying to the ISS with astronauts Suni Williams and Butch Wilmore. NASA decided in late August that the astronauts will come home on a SpaceX Crew Dragon capsule in February for safety reasons. Wilmore and Williams merely provided support for the capsule's trip back home and watched the coverage of its re-entry and landing. "You have got this. We have your backs, and you've got this. Bring her back to Earth," Williams told ground control.
The astronauts flew on the Starliner as part of its first crewed flight meant to prove that the spacecraft is ready to regularly ferry humans to the ISS alongside the SpaceX Crew Dragon. They were only supposed to stay on the orbiting laboratory for eight days, but the spacecraft's service module started leaking helium on their way there. Some of the module's thrusters had malfunctioned, as well. The Starliner uses helium to pressurize its fuel tanks and to push propellant to its thrusters that maneuver the spacecraft. Over the past three months, engineers on the ground conducted tests on Starliner with help from the astronauts, but NASA ultimately decided to have the Starliner fly back home uncrewed because it didn't have confidence with the certainty of the thrusters' performance.
During the Starliner's post-landing press conference, Boeing was noticeably absent, and three NASA officials talked about the landing instead. When asked why Boeing wasn't there and if the relationship between the agency and the company was affected by Starliner's issues, the representatives said that Boeing deferred to NASA to represent the mission. They said that all three of them talked to Boeing's managers and that the company is committed to working with the agency. Steve Stich, the manager for Commercial Crew Program at NASA Kennedy, also added that while all of them were happy with the landing, a part of them still wishes it would've gone the way they'd planned, with the astronauts coming home aboard the Calypso.
Stitch, Joel Montalbano (NASA's deputy associate administrator for Space Operations Mission Directorate) and Dana Weigel (NASA's manager for the International Space Station) all praised the Starliner for its successful docking and "bullseye landing." They said they learned a lot from the mission, which apparently achieved 85 to 90 percent of its objectives, and stressed that it's important to remember that things don't always go as planned when it comes to test flights.
It'll take around two weeks to get the Calypso back to NASA grounds and around a week after that to get all the data from the capsule. NASA and Boeing are planning to analyze the data the spacecraft gathered across its systems from its time in orbit until its undocking, reentry and landing. They will then use that information to design improvements for the spacecraft.
Unfortunately, they wouldn't be able to inspect the thrusters that malfunctioned on the flight to the ISS, as well as the "doghouses" that contained the spacecraft's propellant system where the helium had leaked. They had always planned to discard the service module that contained those elements upon re-entry, and it's now at the bottom of the Pacific Ocean. NASA previously said that the issues cropped up because the propulsion equipment got hotter that expected while flying, causing container seals to loosen and to leak helium. In case of the thrusters, the heat apparently caused seals to bulge and restrict propellant flow, leading to outages.
Stitch said he wouldn't call those problems insurmountable — they just need some time to address them. They also can't tell at the moment if Starliner's next flight would have a crew onboard. For now, the agency is preparing for other missions. By the end of September, the SpaceX Crew-8 mission vehicle is scheduled to undock and come back to Earth, while the SpaceX Crew-9 mission is expected to launch. Crew-9 will fly with two astronauts instead of four to make room for Wilmore and Williams for its return flight in February.

Starliner is scheduled to undock from the International Space Station and make its return trip to Earth uncrewed in just a matter of days, but it apparently still has a few new mysteries left in it to throw at the team before it departs. On Saturday, astronaut Butch Wilmore alerted NASA’s Mission Control about an unexplained “strange noise” coming from a speaker in the spacecraft, which you can hear in an audio clip of the conversation shared on a NASASpaceflight forum by meteorologist Rob Dale (spotted by Ars Technica). It starts at around the 45-second mark, ringing out on a steady beat. “I don’t know what’s making it,” Wilmore said.
NASA has since said that the sound has stopped in a statement to SpaceNews’ Jeff Foust on Monday, and attributed it to an audio configuration between the ISS and Starliner. It was just speaker feedback, according to the space agency.
The noise was a bit of a head-scratcher over the weekend. After confirming with Mission Control on Saturday that they could hear the sound too, once Wilmore brought his mic over to the speaker, the flight controller in Houston said, “It was kind of like a pulsing noise, almost like a sonar ping.” Wilmore then let it play for about 20 seconds more before wrapping up the call. “Just to make sure I’m on the same page, this is emanating from the speaker in Starliner,” Mission Control asked, “you don’t notice anything else, any other noises, any weird configs in there?” The astronaut noted at the time that everything else seemed normal.
“The space station audio system is complex, allowing multiple spacecraft and modules to be interconnected, and it is common to experience noise and feedback,” NASA said in its explanation to Foust on Monday. “The crew is asked to contact mission control when they hear sounds originating in the comm system.” The incident had no impact to the crew or Starliner’s departure schedule, it added.
The Boeing spacecraft has been docked with the ISS since early June, and engineers have since had their hands full trying to get to the bottom of the issues that arose during its first crewed flight. When Starliner finally heads back to Earth on September 6, it’ll be leaving its crew — Wilmore and NASA astronaut Suni Williams — behind on the ISS, where they’ll continue to work for the next few months while they wait for a ride home from SpaceX in February 2025.
Update, September 2 2024, 2:30PM ET: This story has been updated to include a statement and explanation from NASA.

The Starliner is scheduled to undock from the International Space Station and to make its way back to Earth at 6:04PM Eastern time today, September 6. If the weather cooperates and the spacecraft leaves the ISS as planned, it will be landing at White Sands Space Harbor in New Mexico with the help of parachutes to slow its descent and inflated airbags at around 12:03AM ET on September 7. While the ground teams at Starliner Mission Control in Houston and at Boeing Mission Control Center in Florida can control the spacecraft remotely if needed, it will be an uncrewed, fully autonomous flight for the Starliner.
NASA recently announced that Butch Wilmore and Suni Williams, the astronauts that headed to the ISS aboard the Starliner for its first crewed flight, will be coming home on a SpaceX Crew Dragon instead. Wilmore and Williams flew to the ISS in June and were only supposed to spend a little more than a week on the orbiting laboratory. On the way there, however, five of the spacecraft's maneuvering thrusters had failed, and its helium leak problem that previously caused its launch to be pushed back had worsened. Engineers on the ground conducted tests with help from the astronauts on the ISS to determine whether the Starliner was safe for the crew to ride back to Earth. In the end, NASA decided that it's safer for Wilmore and Williams to come home on a SpaceX vehicle, because "there was too much uncertainty" around the Starliner's thrusters.
The space agency will cover Starliner's return live on NASA+, the NASA app, its website, and you can also watch it below. Coverage of the undocking procedure will start at 5:45PM ET, while coverage for the spacecraft's deorbit burn, entry and landing will start at 10:50PM. NASA will also livestream Starliner's landing on September 7, starting at 12AM ET.
As for the SpaceX Crew-9 mission that's replacing the Boeing's vehicle on the ISS, it's scheduled to launch no earlier than September 24. Instead of flying with four astronauts as planned, it will fly with two — NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov — to leave two seats empty for its return flight with Wilmore and Williams in February 2025.
