Boeing Starliner headed back to factory, further delaying launch to ISS

A persistent valve problem remains after the issue scrubbed a second launch attempt earlier this month.

After more than a week trying to fix a problem with stuck valves, Boeing’s Starliner crew capsule is coming off the Atlas V rocket that was meant to send it to orbit for some «deeper-level troubleshooting.» In a call with media on Friday, NASA’s Steve Stich said Starliner now won’t be able to undertake its test flight to the International Space Station until late October at the earliest.

Boeing had hoped to launch Starliner on Aug. 3 in an attempt to dock with the ISS, but the attempt was scrubbed — the second delay in less than a week. Boeing’s first try way back in December 2019 failed to reach the correct orbit but gave it valuable data.

Engineers «detected unexpected valve position indicationsin the propulsion system» during a health check of the spacecraft after electrical storms in the region, Boeing said at the time. It remainsuncertain if the storms were responsible for the technical issue.

The spacecraft was moved off the pad and returned to a hangar (or»vertical integration facility») on Aug. 4 but as of Friday, four valves were still malfunctioning, forcing Boeing to de-stack the vehicle to get a better look at the problem.

«We’ll continueto work the issue from the Starliner factory,» Boeing’s Commercial Crew Program manager John Vollmer said.

He also cast some doubt on the possibility that the capsule will get off the ground in 2021: «It’s probably too early to say whether it’s this year, or not.»

The mission was originally scheduled to take off July 30, but that was delayed due to an issue Thursday with a Russian ISS module firing its thrusters shortly after docking with the station. That knocked the space station around and forced teams to evaluate the station’s status.

When Starliner does finally launch, it will lift off on a United Launch Alliance (ULA) Atlas V rocket. The capsule will be packed with around 400 pounds of crew supplies and cargo. If all goes well, it’ll dock with the space station about 24 hours later. Docking will also be covered live by NASA TV.

Software defects and a communications link problem led to a premature end to the original Boeing test flight in 2019, though the CST-100 Starliner capsule landed safely back on Earth. The upcoming Orbital Flight Test-2 (OFT-2) mission is a chance for Boeing to thoroughly vet its hardware and software before a crew of three American astronauts would fly on Starliner.

Both Boeing and SpaceX are part of NASA’s Commercial Crew Program, which is all about sending astronauts to the ISS from American soil. SpaceX has now delivered 10 astronauts to the ISS, and Boeing would like to catch up. But first, it’ll need to show that its Starliner can safely reach the ISS and return to Earth.

Starliner will spend between five and 10 days at the ISS before bringing research samples back to Earth. Boeing will aim to bring the spacecraft back for a parachute landing in the desert of New Mexico.

«OFT-2 will provide valuable data that will help NASA certify Boeing’s crew transportation system to carry astronauts to and from the space station,» NASA said in a statement July 22 after concluding a flight readiness review.

The mission is a key step for NASA’s plans to run regular crewed launches from the US, ending its reliance on Russian Soyuz spacecraft. Boeing is also looking ahead at its first crewed mission, Boe-CFT, which it had been hoping to launch within the next six months. The delays with OFT-2 could mean a longer wait before people fly on Starliner.

A Historic Heat Dome Is Creeping Across the US. Here’s How to Prepare

After breaking heat records in 14 states, the heat wave pummeling the Southwest is moving eastward.

A massive heat wave has broken heat records in 14 states, including Arizona and California, reaching up to 112 degrees Fahrenheit in some areas. Now it’s creeping eastward, according to the National Weather Service.

The heat wave is continuing its journey through the Midwestern United States and is projected to affect anywhere from one-quarter to one-third of the 48 mainland states, National Weather Service meteorologist Gregg Gallina told The Associated Press. The highest temperatures recorded today are in Arizona, New Mexico and Texas — what the National Weather Service refers to as the Southern Rockies region. But the hot air is on the move.

The reason these high temperatures persist is the «heat dome» phenomenon, in which high pressure prevents hot air from rising, trapping it in a bubble above a region. As the dome of pressure moves, so too does the hot air — and right now, it’s barreling east.

The states that will be smothered by the heat dome in the coming days include those in the Southern and Central Plains regions. This means residents of Texas, Colorado, Oklahoma, Kansas and Nebraska can expect to sweat as the heat blankets them on its eastbound journey.

What the heat dome means for climate change and our health

According to Climate Central, the US has experienced rising blackout rates over the past 20 years, largely due to weather-related issues and an aging electrical grid.

As of August 2025, the US Environmental Protection Agency states that heat is the leading weather-related cause of death in the US. The World Health Organization reports that between 2000 and 2019, about 489,000 heat-related deaths occurred each year.

Fortunately, humidity levels are not as high during a summer heat wave. As humidity can contribute to dehydration, body strain and breathing difficulties, lower humidity makes this heat dome somewhat less dangerous for workers in affected areas.

The World Weather Attribution, an initiative formed by international climate change researchers and climate scientists, determined that the heat dome would be «virtually impossible without human-induced climate change.»

In a world where weather events like these cease to be impossibilities, you’ll want to prepare for future heat waves properly. Here’s how to stay safe during the heat dome.

How to prepare for the heat dome before it hits your state

There’s nothing you can do to beat the heat outside, aside from following heat safety best practices. You’ll just need to stay hydrated, wear breathable, light-colored clothing and wait out the potentially dangerous heat dome, which is expected to dissipate by the end of next week when April begins. But you can do things to batten down the hatches before the sweltering heat reaches your home.

Even if you don’t have much prep time, a couple of small items can make your home safer (and far more comfortable). Cooling towels, portable fans and countertop ice makers are must-haves during a heat wave, especially if you aren’t looking to crank the thermostat down and spend a pretty penny.

Heat waves are also extremely costly due to the sheer amount of energy used — it’s expensive to stay cool. Depending on your living situation, though, you might want to invest in heat pump installation. These HVAC system additions are extremely energy efficient, which means you can keep more money in your pocket while beating the heat.

During the middle of the heat wave, when everyone has their AC running, there’s also the potential for an early brownout (a temporary drop in electrical voltage, causing lighting to dim) or even a blackout (a complete loss of power). It’s common to feel helpless during power outages, but you can get ahead of the curve by preparing a summer blackout kit with portable chargers and alternative light sources before the heat wave hits.

Even if the historic heat wave doesn’t hit your home, these tips will help you prepare as the summer season bears down on the US in a couple of months.

Apple May Give Siri a Big AI Overhaul in iOS 27

Apple is testing a standalone Siri app, a new interface and deeper AI features for this year’s software update, Bloomberg reports.

Apple may be planning one of the biggest changes to Siri since the voice assistant launched more than a decade ago. According to a report on Tuesday from Bloomberg, Apple is testing a standalone Siri app, a redesigned interface and a new «Ask Siri» button that would make the assistant more visible and useful across the Apple ecosystem, as part of a broader AI reboot.

According to the Bloomberg report, the new Siri experience is expected to be introduced at Apple’s Worldwide Developers Conference on June 8 and would arrive as part of iOS 27, iPadOS 27 and MacOS 27 later this year. The report says Apple is testing out a new Siri that would make the assistant feel more like a standalone AI chatbot — think ChatGPT or Claude — rather than the current built-in tool.

The latest report builds on earlier Bloomberg reporting from January, which said Apple planned to revamp Siri into its first real AI chatbot to better compete with OpenAI and Google.

For Apple, the move would mark another attempt to reset expectations around its AI strategy after repeated delays to its more advanced Siri ambitions. Apple had previewed a more personalized Siri at WWDC 2024, but the broader rollout has slipped, and Bloomberg’s new report suggests the company is now aiming for a more sweeping relaunch in iOS 27 instead.

Apple has not publicly announced these iOS 27 features, so plans could still change before WWDC.

An Apple representative didn’t immediately respond to a request for comment.
