Dear Commons Community,

Elon Musk’s company SpaceX launched its huge Starship rocket on the program’s eighth test flight yesterday, but a malfunction  triggered multiple upper stage engine shutdowns and the vehicle failed to reach its planned sub-orbital altitude, breaking apart in a spectacular shower of debris.

It was the second failure in a row for a Starship upper stage, a vehicle critical to NASA’s plans to return astronauts to the moon in the next few years.  As reported by CBS News.

“During Starship’s ascent burn, the vehicle experienced a rapid unscheduled disassembly and contact was lost. Our team immediately began coordination with safety officials to implement pre-planned contingency responses,” SpaceX said in a statement.

“We will review the data from today’s flight test to better understand root cause. As always, success comes from what we learn, and today’s flight will offer additional lessons to improve Starship’s reliability.”

“Obviously, a lot to go through, a lot to dig through. We’re going to go right at it,” said SpaceX launch commentator Dan Huot. “The primary reason we do these flight tests is to learn. We have some more to learn about this vehicle, but we’re going to be right back here in the not-too-distant future, and we’re going to get a ship to space.”

The Federal Aviation Administration said it has ordered a mishap investigation into the loss of the Starship.

Flights at several Florida airports were temporarily grounded due to the risk of falling debris.

Ground stops have now been lifted, but the FAA reported Miami International Airport and Fort Lauderdale–Hollywood International Airport both had departure delays of about 45 minutes, with the cause listed as “space launch debris.” Flights at Palm Beach International Airport and Orlando International Airport were also affected.

“During the event, the FAA activated a Debris Response Area and briefly slowed aircraft outside the area where space vehicle debris was falling or stopped aircraft at their departure location. Normal operations have resumed,” the agency said.

Three days after a last-minute scrub due to unspecified technical issues, SpaceX fired up the Super Heavy first stage’s 33 methane-fueled Raptor engines at 6:30 p.m. EST. Two seconds later, the tallest, most powerful rocket in the world lifted off from the company’s launch site on the Texas Gulf Coast.

Capable of generating up to 16 million pounds of thrust — more than twice the power as NASA’s Saturn 5 moon rocket — the Super Heavy-Starship arced away to the east atop of long jet of bluish flame.

After boosting the Starship upper stage out of the dense lower atmosphere, the 230-foot-tall, 30-foot-wide Super Heavy first stage booster flew itself back to the launch site and into the grasp of two giant mechanical arms known as “chopsticks” mounted on the side of the launch tower.

The 160-foot-tall Starship upper stage, meanwhile, climbed toward space as planned on the power of six Raptor engines, appearing to work flawlessly as it soared skyward toward the planned sub-orbital trajectory.

But a little more than eight minutes after liftoff, telemetry shown on SpaceX’s live webcast indicated four of the six engines had prematurely shut down. A camera on the Starship showed the spacecraft starting to spin about and several seconds later contact was lost.

Multiple videos posted on social media showed a dramatic shower of debris arcing back toward Earth after the vehicle broke up. It wasn’t immediately clear if the breakup was triggered by the Starship’s self-destruct system or by extreme structural loads as it fell back into the lower atmosphere.

While SpaceX will no doubt attempt its usual rapid recovery, the Federal Aviation Administration will almost certainly order another failure investigation. Given two destructive breakups in a row, it could take longer to return to flight status this time around.

Musk’s comment on his latest SpaceX disaster – “rockets are hard.”
