After years of lobbying, protests, and bidding, Jeff Bezos's space company is now a military launch contractor.

The US Space Force announced Thursday that Blue Origin will compete with United Launch Alliance and SpaceX for at least 30 military launch contracts over the next five years. These launch contracts have a combined value of up to $5.6 billion.

This is the first of two major contract decisions the Space Force will make this year as the military seeks to foster more competition among its roster of launch providers and reduce its reliance on just one or two companies.

Let’s unpack some questions about Russia’s role in North Korea’s rocket program

Russian President Vladimir Putin will reportedly visit North Korea later this month, and you can bet collaboration on missiles and space programs will be on the agenda.

The bilateral summit in Pyongyang will follow a mysterious North Korean rocket launch on May 27, which ended in a fireball over the Yellow Sea. The fact that this launch fell short of orbit is not unusualβ€”two of the country's three previous satellite launch attempts failed. But North Korea's official state news agency dropped some big news in the last paragraph of its report on the May 27 launch.

The Korean Central News Agency called the launch vehicle a "new-type satellite carrier rocket" and attributed the likely cause of the failure to "the reliability of operation of the newly developed liquid oxygen + petroleum engine" on the first stage booster. A small North Korean military spy satellite was destroyed. The fiery demise of the North Korean rocket was captured in a video recorded by the Japanese news broadcaster NHK.

Boeing’s Starliner finally soars, but mission control reports more helium leaks

After years of delays, Boeing's Starliner spacecraft finally rocketed into orbit from Florida on Wednesday, sending two veteran NASA astronauts on a long-delayed shakedown cruise to the International Space Station.

The Starliner capsule lifted off at 10:52 am EDT (14:52 UTC) on top of a United Launch Alliance Atlas V rocket. Fifteen minutes later, after shedding two strap-on boosters and a core stage powered by a Russian RD-180 engine, the Atlas V's Centaur upper stage released Starliner right on target to begin a nearly 26-hour pursuit of the space station. Docking at the space station is set for 12:15 pm EDT (16:15 UTC) Thursday, where NASA astronauts Butch Wilmore and Suni Williams will spend at least a week before coming back to Earth.

In remarks shortly after Wednesday's launch, NASA Administrator Bill Nelson said Wilmore and Williams, both former US Navy pilots, will "test this thing from izzard to gizzard" to ensure Boeing's Starliner is ready for operational six-month crew rotation missions to the ISS.

Countdown begins for third try launching Boeing’s Starliner crew capsule

Fresh off repairs at the launch pad in Florida, United Launch Alliance engineers restarted the countdown overnight for the third attempt to send an Atlas V rocket and Boeing's Starliner spacecraft on a test flight to the International Space Station.

NASA astronauts Butch Wilmore and Suni Williams were expected to awake early Wednesday, put on their blue pressure suits, and head to the launch pad at Cape Canaveral Space Force Station to board the Starliner capsule on top of the 172-foot-tall Atlas V rocket.

Once more through the door

Wilmore and Williams have done this twice before in hopes of launching into space on the first crew flight of Boeing's Starliner spacecraft. A faulty valve on the Atlas V rocket prevented liftoff May 6, then engineers discovered a helium leak on the Starliner capsule itself. After several weeks of troubleshooting, NASA and Boeing officials decided to proceed with another launch attempt Saturday.

SpaceX is about to launch Starship againβ€”the FAA will be more forgiving this time

The rocket for SpaceX's fourth full-scale Starship test flight awaits liftoff from Starbase, the company's private launch base in South Texas.

The Federal Aviation Administration approved the commercial launch license for the fourth test flight of SpaceX's Starship rocket Tuesday, with liftoff from South Texas targeted for just after sunrise Thursday.

"The FAA has approved a license authorization for SpaceX Starship Flight 4," the agency said in a statement. "SpaceX met all safety and other licensing requirements for this test flight."

Shortly after the FAA announced the launch license, SpaceX confirmed plans to launch the fourth test flight of the world's largest rocket at 7:00 am CDT (12:00 UTC) Thursday. The launch window runs for two hours.

Boeing’s Starliner test flight scrubbed again after hold in final countdown

NASA commander Butch Wilmore exits the Starliner spacecraft Saturday following the scrubbed launch attempt.

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.Β North Korea's latest attempt to launch a rocket with a military reconnaissance satelliteΒ 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.

US officials: A Russian rocket launch last week likely deployed a space weapon

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."
