A computer controlling the Atlas V rocket's countdown triggered an automatic hold less than four minutes prior to liftoff of Boeing's commercial Starliner spacecraft Saturday, keeping the crew test flight on the ground at least a few more days.

NASA astronauts Butch Wilmore and Suni Williams were already aboard the spacecraft when the countdown stopped due to a problem with a ground computer. "Hold. Hold. Hold," a member of Atlas V launch team called out on an audio feed.

With the hold, the mission missed an instantaneous launch opportunity at 12:25 pm EDT (16:25 UTC), and later Saturday, NASA announced teams will forego a launch opportunity Sunday. The next chance to send Starliner into orbit will be 10:52 am EDT (14:52 UTC) Wednesday. The mission has one launch opportunity every one-to-two days, when the International Space Station's orbital track moves back into proper alignment with the Atlas V rocket's launch pad in Florida.

Welcome to Edition 6.46 of the Rocket Report! It looks like we will be covering the crew test flight of Boeing's Starliner spacecraft and the fourth test flight of SpaceX's giant Starship rocket over the next week. All of this is happening as SpaceX keeps up its cadence of flying multiple Starlink missions per week. The real stars are the Ars copy editors helping make sure our stories don't use the wrong names.

Another North Korean launch failure. North Korea's latest attempt to launch a rocket with a military reconnaissance satellite ended in failure due to the midair explosion of the rocket during the first-stage flight this week, South Korea's Yonhap News Agency reports. Video captured by the Japanese news organization NHK appears to show the North Korean rocket disappearing in a fireball shortly after liftoff Monday night from a launch pad on the country's northwest coast. North Korean officials acknowledged the launch failure and said the rocket was carrying a small reconnaissance satellite named Malligyong-1-1.

The launch of a classified Russian military satellite last week deployed a payload that US government officials say is likely a space weapon.

In a series of statements, US officials said the new military satellite, named Kosmos 2576, appears to be similar to two previous "inspector" spacecraft launched by Russia in 2019 and 2022.

"Just last week, on May 16, Russia launched a satellite into low-Earth orbit that the United States assesses is likely a counter-space weapon presumably capable of attacking other satellites in low-Earth orbit," said Robert Wood, the deputy US ambassador to the United Nations. "Russia deployed this new counter-space weapon into the same orbit as a US government satellite."

After three test flights, SpaceX has shown that the world's most powerful rocket can reach space. Now, engineers must demonstrate the company's next-generation Starship vehicle can get back home.

This will be the central objective for the fourth Starship test flight, which could happen as soon as early June, according to Elon Musk, SpaceX's founder and CEO.

"Starship Flight 4 in about 2 weeks," Musk posted on X, his social media platform, following a Starship countdown rehearsal Monday at the Starship launch site in South Texas. "Primary goal is getting through max reentry heating."

More than 60 years after he was denied an opportunity to become America's first Black astronaut, Ed Dwight finally traveled into space Sunday with five other passengers on a 10-minute flight inside a Blue Origin capsule.

Dwight, a retired Air Force captain and test pilot, had a chance to become the first African American astronaut. He was one of 26 pilots the Air Force recommended to NASA for the third class of astronauts in 1963, but the agency didn't select him. It took another 20 years for America's first Black astronaut, Guion Bluford, to fly in space in 1983.

“Everything they did, I did, and I did it well," Dwight said in a video released by Blue Origin. "If politics had changed, I would have gone to space in some kind of capacity.”

There are a couple of ways to read the announcement from the Federal Aviation Administration that it's kicking off a new environmental review of SpaceX's plan to launch the most powerful rocket in the world from Florida.

The FAA said on May 10 that it plans to develop an Environmental Impact Statement (EIS) for SpaceX's proposal to launch Starships from NASA's Kennedy Space Center in Florida. The FAA ordered this review after SpaceX updated the regulatory agency on the projected Starship launch rate and the design of the ground infrastructure needed at Launch Complex 39A (LC-39A), the historic launch pad once used for Apollo and Space Shuttle missions.

Dual environmental reviews

At the same time, the US Space Force is overseeing a similar EIS for SpaceX's proposal to take over a launch pad at Cape Canaveral Space Force Station, a few miles south of LC-39A. This launch pad, designated Space Launch Complex 37 (SLC-37), is available for use after United Launch Alliance's last Delta rocket lifted off there in April.

Welcome to Edition 6.44 of the Rocket Report! Kathy Lueders, general manager of SpaceX's Starbase launch facility, says the company expects to receive an FAA launch license for the next Starship test flight shortly after Memorial Day. It looks like this rocket could fly in late May or early June, about two-and-a-half months after the previous Starship test flight. This is an improvement over the previous intervals of seven months and four months between Starship flights.

Blue Origin launch on tap this weekend. Blue Origin plans to launch its first human spaceflight mission in nearly two years on Sunday. This flight will launch six passengers on a flight to suborbital space more than 60 miles (100 km) over West Texas. Blue Origin, Jeff Bezos's space company, has not flown people to space since a New Shepard rocket failure on an uncrewed research flight in September 2022. The company successfully launched New Shepard on another uncrewed suborbital mission in December.
