The Federal Aviation Administration said Friday it has closed an investigation into the problems SpaceX encountered on its first full-scale Starship test launch in April, but federal regulators won't yet give a green light for the next Starship flight.

"The closure of the mishap investigation does not signal an immediate resumption of Starship launches at Boca Chica," the FAA said in a statement, referring to the location of SpaceX's Starship launch facility at Boca Chica Beach in South Texas.

The nearly 400-foot-tall Starship rocket, the largest ever built, is standing on its launch pad in Texas for the upcoming test flight, which could happen before the end of this month, pending FAA approval.

Welcome to Edition 6.10 of the Rocket Report! A Japanese spacecraft has joined the international flock of missions traveling to the Moon this year, but you'll need to practice patience on this one. It will take about four months for Japan's small lander to get into lunar orbit, then more weeks to align with the mission's target landing site. We're crossing our fingers this lander will see the same success as India's Chandrayaan 3 mission.

India launches its first solar research satellite . Less than two weeks after landing its first mission on the Moon, India launched a solar observatory on September 2 toward an orbit nearly a million miles (1.5 million kilometers) from Earth around the L1 Lagrange point. This mission, named Aditya-L1, lifted off on India's workhorse Polar Satellite Launch Vehicle and entered orbit around the Earth, where the spacecraft is expected to perform five maneuvers to escape Earth's gravity and head to its distant observation post.

On Tuesday, SpaceX stacked its Starship rocket on top of a Super Heavy booster in South Texas, beginning final preparations for a second launch attempt of the massive vehicle.

After the stacking operations were complete, SpaceX founder Elon Musk posted on X, the site formerly known as Twitter, that "Starship is ready to launch, awaiting FAA license approval."

That caveat is a big one because the Federal Aviation Administration is still reviewing paperwork and data from SpaceX about the first launch attempt of Starship in April 2023. That flight ended after about 90 seconds due to engine problems and other issues with the booster. The FAA has been reviewing data from that accident, including the environmental implications at the launch site and the delayed activation of the rocket's flight termination system.

The Federal Aviation Administration is now reviewing a mishap investigation report submitted by SpaceX regarding the company's April test flight of its giant Starship rocket, a spokesperson for the regulatory agency said Tuesday.

The milestone is noteworthy because it signals SpaceX has completed its investigation into the Starship test launch on April 20 , which ended about four minutes after liftoff following engine failures and other problems during ascent. Now comes the FAA's review of SpaceX's investigation, fulfilling the agency's role as the regulator charged with ensuring public safety during commercial launch operations.

"When a final mishap report is approved, it will identify the corrective actions SpaceX must make," an FAA spokesperson told Ars. "Separately, SpaceX must modify its license to incorporate those actions before receiving authorization to launch again.

Welcome to Edition 6.04 of the Rocket Report! SpaceX has a Super Heavy booster on the launch pad in Texas a lot sooner than many thought. There was some pretty extensive damage at the launch site in the aftermath of the Starship test launch in April, SpaceX made quick work with repairs and upgrades to beef up the pad. Meanwhile, SpaceX's Falcon 9 launcher, Rocket Lab's Electron, and China's rocket fleet show no signs of slowing down.

China's Galactic Energy launches sixth successful mission . Galactic Energy, one of several new Chinese startup launch companies, launched its sixth consecutive successful satellite delivery mission on July 22, Space News reports . The company's solid-fueled Ceres 1 rocket lifted off from the Jiuquan launch base in the Gobi Desert with two small satellites on board. Galactic Energy is also developing a medium-lift rocket named Pallas 1 that is designed to eventually be recoverable and reusable.

In 2004, Congress passed a law that established a moratorium on federal safety regulations for commercial astronauts and space tourists riding to space on new privately owned rockets and spacecraft. The idea was to allow time for new space companies to establish themselves before falling under the burden of regulations, an eventuality that spaceflight startups argued could impede the industry's development.

The moratorium is also known as a "learning period," a term that describes the purpose of the provision. It's supposed to give companies and the Federal Aviation Administration—the agency tasked with overseeing commercial human spaceflight, launch, and re-entry operations—time to learn how to safely fly in space and develop smart regulations, those that make spaceflight safer but don't restrict innovation.

Without action from Congress, by the end of September, the moratorium on human spaceflight regulations will expire. That has many in the commercial space industry concerned.

The heaviest commercial communications satellite ever built is folded up for launch on top of a SpaceX Falcon Heavy rocket Wednesday night from NASA's Kennedy Space Center in Florida.

This satellite, owned by EchoStar and built by Maxar, tips the scales at about 9.2 metric tons, or more than 20,000 pounds. SpaceX's Falcon Heavy will propel the spacecraft on its way toward an operating position in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

The action will begin at 11:04 p.m. EDT (03:04 UTC) with the ignition of the Falcon Heavy's 27 main engines on Launch Complex 39A. A few moments later, the Falcon Heavy will climb away from its launch pad and head downrange toward the east from the Kennedy Space Center. You can watch SpaceX's live webcast below.

The late-night liftoff of a Falcon 9 rocket with another batch of Starlink Internet satellites on Sunday set a new record for the most flights by a SpaceX launch vehicle, with a first-stage booster flying for a 16th time. SpaceX now aims to fly its reusable Falcon 9 boosters as many as 20 times, double the company’s original goal.

The flight followed several months of inspections and refurbishment of SpaceX’s most-flown rocket, a process that included a “recertification” of the booster to prove, at least on paper, that it could fly as many as five more times after completing its 15th launch and landing last December.

Sunday night’s mission got the booster’s extended life off to a good start.
