A little more than two years ago, Dmitry Rogozin, the bellicose former head of Russia's space agency, nearly brought the International Space Station partnership to its knees.

During his tenure as director general of Roscosmos, Rogozin was known for his bombastic social media posts and veiled threats to abandon the space station after Russia's invasion of Ukraine. Russian President Vladimir Putin tersely dismissed Rogozin in July 2022 and replaced him with Yuri Borisov, a former deputy prime minister.

While the clash between Russia and Western governments over the war in Ukraine has not cooled, the threats against the International Space Station (ISS) ended. The program remains one of the few examples of cooperation between the US and Russian governments. Last year, Russia formally extended its commitment to the ISS to at least 2028. NASA and space agencies in Europe, Japan, and Canada have agreed to maintain the space station through 2030.

All at once, India's government has approved plans to develop a new reusable rocket, the centerpiece of an Indian space station, a robotic sample return mission to the Moon, and a science probe to explore Venus.

"Great news for the space sector!" Indian Prime Minister Narendra Modi posted on X. Collectively, the projects authorized by India's union cabinet will cost an estimated $2.7 billion. Most of the funding will go toward the country's space station and a reusable launch vehicle.

If the projects reach their goals, the approvals announced by Modi on Wednesday will put India on a trajectory to become the third-largest space power in the 2030s, after the United States and China. V. Narayanan, director of India's Liquid Propulsion Systems Center, stated this was the objective in a recent presentation, writing that India's space initiatives will catapult the country to a place "among the three important space powers in the world."

Welcome to Edition 7.11 of the Rocket Report! Outside of companies owned by American billionaires, the most imminent advancements in reusable rockets are coming from China's quasi-commercial launch industry. This industry is no longer nascent. After initially relying on solid-fueled rocket motors apparently derived from Chinese military missiles, China's privately funded launch firms are testing larger launchers, with varying degrees of success, and now performing hop tests reminiscent of SpaceX's Grasshopper and F9R Dev1 programs more than a decade ago.

As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Landspace hops closer to a reusable rocket. Chinese private space startup Landspace has completed a 10-kilometer (33,000-foot) vertical takeoff and vertical landing test on its Zhuque-3 (ZQ-3) reusable rocket testbed, including a mid-flight engine reignition at near supersonic conditions, Aviation Week & Space Technology reports. The 18.3-meter (60-foot) vehicle took off from the Jiuquan launch base in northwestern China, ascended to 10,002 meters, and then made a vertical descent and achieved an on-target propulsive landing 3.2 kilometers (2 miles) from the launch pad. Notably, the rocket's methane-fueled variable-thrust engine intentionally shutdown in flight, then reignited for descent, as engines would operate on future full-scale booster flybacks. The test booster used grid fins and cold gas thrusters to control itself when its main engine was dormant, according to Landspace.

Boeing's Starliner spacecraft sailed to a smooth landing in the New Mexico desert Friday night, an auspicious end to an otherwise disappointing three-month test flight that left the capsule's two-person crew stuck in orbit until next year.

Cushioned by airbags, the Boeing crew capsule descended under three parachutes toward an on-target landing at 10:01 pm local time Friday (12:01 am EDT Saturday) at White Sands Space Harbor, New Mexico. From the outside, the landing appeared just as it would have if the spacecraft brought home NASA astronauts Butch Wilmore and Suni Williams, who became the first people to launch on a Starliner capsule on June 5.

But Starliner's cockpit was empty as it flew back to Earth Friday night. Last month, NASA managers decided to keep Wilmore and Williams on the International Space Station (ISS) until next year after agency officials determined it was too risky for the astronauts to return to the ground on Boeing's spaceship. Instead of coming home on Starliner, Wilmore and Williams will fly back to Earth on a SpaceX Dragon spacecraft in February. NASA has incorporated the Starliner duo into the space station's long-term crew.

Boeing's Starliner spacecraft will gently back away from the International Space Station Friday evening, then fire its balky thrusters to rapidly depart the vicinity of the orbiting lab and its nine-person crew.

NASA asked Boeing to adjust Starliner's departure sequence to get away from the space station faster and reduce the workload on the thrusters to reduce the risk of overheating, which caused some of the control jets to drop offline as the spacecraft approached the outpost for docking in June.

The action begins at 6:04 pm EDT (22:04 UTC) on Friday, when hooks in the docking mechanism connecting Starliner with the International Space Station (ISS) will open, and springs will nudge the spacecraft away its mooring on the forward end of the massive research complex.

NASA is ready for Boeing's Starliner spacecraft, stricken with thruster problems and helium leaks, to leave the International Space Station as soon as Friday, wrapping up a disappointing test flight that has clouded the long-term future of the Starliner program.

Astronauts Butch Wilmore and Suni Williams, who launched aboard Starliner on June 5, closed the spacecraft's hatch Thursday in preparation for departure Friday. But it wasn't what they envisioned when they left Earth on Starliner three months ago. Instead of closing the hatch from a position in Starliner's cockpit, they latched the front door to the spacecraft from the space station's side of the docking port.

The Starliner spacecraft is set to undock from the International Space Station at 6:04 pm EDT (22:04 UTC) Friday. If all goes according to plan, Starliner will ignite its braking rockets at 11:17 pm EDT (03:17 UTC) for a minute-long burn to target a parachute-assisted, airbag-cushioned landing at White Sands Space Harbor, New Mexico, at 12:03 am EDT (04:03 UTC) Saturday.

NASA and Boeing are proceeding with final preparations to undock the Starliner spacecraft from the International Space Station next Friday, September 6, to head for landing at White Sands Space Harbor in southern New Mexico.

Astronauts Butch Wilmore and Suni Williams, who were supposed to return to Earth inside Starliner, will remain behind on the space station after NASA decided last week to conclude the Boeing test flight without its crew on board. NASA officials decided it was too risky to put the astronauts on Starliner after the spacecraft suffered thruster failures during its flight to the space station in early June.

Instead, Wilmore and Williams will come home on a SpaceX Dragon capsule no earlier than February, extending their planned stay on the space station from eight days to eight months. Flying on autopilot, the Starliner spacecraft is scheduled to depart the station at approximately 6:04 pm EDT (22:04 UTC) on September 6. The capsule will fire its engines to drop out of orbit and target a parachute-assisted landing in New Mexico at 12:03 am EDT (04:03 UTC) on September 7, NASA said in a statement Thursday.

Ten years ago next month, NASA announced that Boeing, one of the agency's most experienced contractors, won the lion's share of government money available to end the agency's sole reliance on Russia to ferry its astronauts to and from low-Earth orbit.

At the time, Boeing won $4.2 billion from NASA to complete the development of the Starliner spacecraft and fly a minimum of two, and potentially up to six, operational crew flights to rotate crews between Earth and the International Space Station (ISS). SpaceX won a $2.6 billion contract for essentially the same scope of work.

A decade later, the Starliner program finds itself at a crossroads after Boeing learned it will not complete the spacecraft's first Crew Flight Test with astronauts onboard. NASA formally decided Saturday that Butch Wilmore and Suni Williams, who launched on the Starliner capsule on June 5, will instead return to Earth in a SpaceX Crew Dragon spacecraft. Put simply, NASA isn't confident enough in Boeing's spacecraft after it suffered multiple thruster failures and helium leaks on the way to the ISS.

Senior NASA leaders, including the agency's administrator, Bill Nelson, will meet Saturday in Houston to decide whether Boeing's Starliner spacecraft is safe enough to ferry astronauts Butch Wilmore and Suni Williams back to Earth from the International Space Station.

The Flight Readiness Review (FRR) is expected to conclude with NASA's most consequential safety decision in nearly a generation. One option is to clear the Starliner spacecraft to undock from the space station in early September with Wilmore and Williams onboard, as their flight plan initially laid out, or to bring the capsule home without its crew.

As of Thursday, the two veteran astronauts have been on the space station for 77 days, nearly 10 times longer than their planned stay of eight days. Wilmore and Williams were the first people to launch and dock at the space station aboard a Starliner spacecraft, but multiple thrusters failed and the capsule leaked helium from its propulsion system as it approached the orbiting complex on June 6.

NASA would like to start stacking the Space Launch System rocket for the Artemis II missionβ€”the first human flight around the Moon since 1972β€”sometime next month, but the agency's exploration chief says the milestone could be delayed as engineers continue studying the readiness of the Orion spacecraft's heat shield.

The heat shield, already installed at the base of the Orion spacecraft, will take the brunt of the heating when the capsule blazes through Earth's atmosphere at the end of the 10-day mission. On the Artemis I test flight in late 2022, NASA sent an Orion spacecraft to the Moon and back without a crew aboard. The only significant blemish on the test flight was a finding that charred chunks of the heat shield unexpectedly stripped away from the capsule during reentry as temperatures increased to nearly 5,000Β° Fahrenheit (2,760Β° Celsius).

The spacecraft safely splashed down, and if any astronauts had been aboard, they would have been fine. However, the inspections of the recovered spacecraft showed divots of heat shield material were missing. The heat shield material, called Avcoat, is designed to erode away in a controlled manner during reentry. Instead, fragments fell off the heat shield that left cavities resembling potholes.

With no consensus on the safety of the Starliner crew capsule, NASA officials said Wednesday they need another week or two before deciding whether to bring two astronauts back to Earth on Boeing's spacecraft or extend their stay on the International Space Station until next year.

Boeing's Starliner spacecraft, stricken by suspect thrusters and helium leaks, is taking up a valuable parking spot at the space station. It needs to depart the orbiting research complex, with or without its two-person crew, before the launch of SpaceX's next Dragon crew mission to the station, scheduled for September 24.

"We can juggle things and make things work if we need to extend, but it’s getting a lot harder," said Ken Bowersox, associate administrator of NASA's spaceflight operations directorate. "With the consumables we’re using, with the need for the use of the ports for cargo missions, those types of things, we’re reaching a point where that last week in August, we really should be making a call, if not sooner.”

As soon as this week, NASA officials will make perhaps the agency's most consequential safety decision in human spaceflight in 21 years.

NASA astronauts Butch Wilmore and Suni Williams are nearly 10 weeks into a test flight that was originally set to last a little more than one week. The two retired US Navy test pilots were the first people to fly into orbit on Boeing's Starliner spacecraft when it launched on June 5. Now, NASA officials aren't sure Starliner is safe enough to bring the astronauts home.

Three of the managers at the center of the pending decision, Ken Bowersox and Steve Stich from NASA and Boeing's LeRoy Cain, either had key roles in the ill-fated final flight of Space Shuttle ColumbiaΒ in 2003 or felt the consequences of the accident.

Sometime next year, SpaceX will begin returning its Dragon crew and cargo capsules to splashdowns in the Pacific Ocean and end recoveries of the spacecraft off the coast of Florida.

This will allow SpaceX to make changes to the way it brings Dragons back to Earth and eliminate the risk, however tiny, that a piece of debris from the ship's trunk section might fall on someone and cause damage, injury, or death.

"After five years of splashing down off the coast of Florida, we've decided to shift Dragon recovery operations back to the West Coast," said Sarah Walker, SpaceX's director of Dragon mission management.

The astronauts who rode Boeing's Starliner spacecraft to the International Space Station last month still don't know when they will return to Earth.

Astronauts Butch Wilmore and Suni Williams have been in space for 51 days, six weeks longer than originally planned, as engineers on the groundwork through problems with Starliner's propulsion system.

The problems are twofold. The spacecraft's reaction control thrusters overheated, and some of them shut off as Starliner approached the space station June 6. A separate, although perhaps related, problem involves helium leaks in the craft's propulsion system.

The central piece of NASA's second Space Launch System rocket arrived at Kennedy Space Center in Florida this week. Agency officials intend to start stacking the towering launcher in the next couple of months for a mission late next year carrying a team of four astronauts around the Moon.

The Artemis II mission, officially scheduled for September 2025, will be the first voyage by humans to the vicinity of the Moon since the last Apollo lunar landing mission in 1972. NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian mission specialist Jeremy Hansen will ride the SLS rocket away from Earth, then fly around the far side of the Moon and return home inside NASA's Orion spacecraft.

"The core is the backbone of SLS, and it’s the backbone of the Artemis mission," said Matthew Ramsey, NASA's mission manager for Artemis II. "We’ve been waiting for the core to get here because all the integrated tests and checkouts that we do have to have the core stage. It has the flight avionics that drive the whole system. The boosters are also important, but the core is really the backbone for Artemis. So it’s a big day.”

Before clearing Boeing's Starliner crew capsule to depart the International Space Station and head for Earth, NASA managers want to ensure the spacecraft's problematic control thrusters can help guide the ship's two-person crew home.

The two astronauts who launched June 5 on the Starliner spacecraft's first crew test flight agree with the managers, although they said Wednesday that they're comfortable with flying the capsule back to Earth if there's any emergency that might require evacuation of the space station.

NASA astronauts Butch Wilmore and Suni Williams were supposed to return to Earth weeks ago, but managers are keeping them at the station as engineers continue probing thruster problems and helium leaks that have plagued the mission since its launch.

NASA and Boeing officials pushed back Friday on headlines that the commercial Starliner crew capsule is stranded at the International Space Station but said they need more time to analyze data before formally clearing the spacecraft for undocking and reentry.

Two NASA astronauts, commander Butch Wilmore and pilot Suni Williams, will spend at least a few more weeks on the space station as engineers on the ground conduct thruster tests to better understand issues with the Starliner propulsion system in orbit. Wilmore and Williams launched June 5 aboard an Atlas V rocket and docked at the station the next day, completing the first segment of Starliner's first test flight with astronauts.

NASA managers originally planned for the Starliner spacecraft to remain docked at the space station for at least eight days, although they left open the possibility of a mission extension. The test flight is now likely to last at least a month and a half, and perhaps longer, as engineers wrestle with helium leaks and thruster glitches on Starliner's service module.

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.

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.
