SpaceX's Starship test flight makes it to space, but lost before ...

SpaceX's Starship mega-rocket launched from Texas Thursday on its third test flight, staying intact longer than during the previous two flights but not making it all the way to its planned splashdown in the Indian Ocean.

During a live webcast of the flight, SpaceX commentators said mission control lost communication with the spacecraft during its atmospheric re-entry. No people or cargo were aboard.

Minutes after launch from the southern tip of Texas at 8:25 a.m. CT, the booster separated seamlessly from the spaceship and splashed down in the Gulf of Mexico.

The spacecraft cruised halfway around the globe for about an hour and had been nearing its Indian Ocean splashdown when communications were cut off.

External cameras captured the plasma field generated as SpaceX's Starship re-entered Earth's atmosphere during the third test flight of the company's mega rocket on Thursday. The company later said the spacecraft was destroyed during re-entry.

A few minutes later, SpaceX confirmed the spacecraft had been lost, presumably burning up or coming apart during re-entry or crashing into the sea.

Still, completion of most of the intended test flight trajectory of Starship marked a major milestone in the development of a spacecraft crucial to Elon Musk's satellite launch business and NASA's moon program.

Musk congratulated his team on social media. "SpaceX has come a long way," he said via X.

The rocket company was founded exactly 22 years ago Thursday. 

Dreams of humans on Mars

The 122-metre (or 37-storey) rocket is Musk's pet project, which he says will not only be able to spit out ever more Starlink satellites but also eventually take humans to Mars. 

A variation of the SpaceX vessel, called the Human Landing System (HLS), will be critical to putting humans on the lunar surface. In order to do so, SpaceX needs to clear a number of hurdles, including demonstrating a ship-to-ship transfer of fuel.

Before today, Starship had seen only incremental achievements.

This launch was referred to as Starship's integrated flight test three (IFT-3), as it is the third time that both the booster and the spaceship itself were launched together. 

From the public's perspective, IFT-1 and IFT-2 were unmitigated failures. 

In the first, last April, the rocket cleared its gargantuan tower before blowing up just four minutes later — Musk and his fans like to use the term "a rapid unscheduled disassembly" — before the booster stage and spaceship could separate.

And that was only what happened in the air. 

Back on terra firma, the aftermath was vast. Because IFT-1 went up without a launch suppression system at the pad — something to soften the fiery blast and shockwave — its 33 engines left an enormous crater below the launch pad. Debris was scattered for kilometres, leading to a barrage of recommendations from federal officials about how to best minimize the harm to the surrounding ecosystem by future launches. 

The second test flight, last November, had a suppression system in place and caused minimal damage to the pad. The rocket successfully lifted off and the two stages managed to separate successfully — a demonstration of a new way of separation called "hot staging." 

Unfortunately, the first stage was lost in an explosion. The second managed to make it into space, reaching 149 kilometres, before it, too, exploded.

While explosions aren't something the public typically deems as achievements, that's not the way space watchers necessarily see it. And certainly not SpaceX.

It deemed IFT-1 a success because it cleared the pad without exploding.

The second was touted as a success for proving that hot-staging — when the second stage booster ignites as the first separates — worked. And, as Musk said later, the second stage reached space before exploding.

But with Artemis III breathing down its neck, SpaceX needed to rack up more concrete wins.

NASA chief Bill Nelson congratulated SpaceX on what he called "a successful test flight" in a statement posted on X.

Before the third flight, engineer and former NASA official Dan Dumbacher said he was hesitant to label the first two Starship launches as either successes or failures.

WATCH | Starship critical for planned Mars mission: 

The SpaceX Starship rocket is a critical part of NASA's plans. CBC’s science reporter Nicole Mortillaro explains why the explosion of the massive rocket isn’t hampering plans to send astronauts to Mars.

"If I had been looking at it with my old NASA badge on in my old NASA world, they're failures, because NASA has to operate in an environment where [they've] got, as I say, 536 investors watching over my shoulder, making sure I'm using public money appropriately," he said.

For SpaceX and others in the private sector, it's "a little bit of a different ball game," said Dumbacher, who is now CEO of the  American Institute of Aeronautics and Astronautics.

"When you have Elon, or [Jeff Bezos] funding things, the buck all stops with them" — their private money allows them to operate differently, being somewhat less risk averse than NASA.

But with NASA relying on the triumph of commercial entities, things begin to change: progress needs to be made.

Paul Fjeld, who collaborated with NASA during the Apollo program, is confident that despite the enormous challenges ahead, SpaceX can rise to the occasion, though perhaps not in the current timeline.

"The engineering chops are there, and that's been demonstrated since the start of it," he said. 

WATCH | Second test flight ends in explosions:

SpaceX's uncrewed spacecraft Starship, developed to carry astronauts to the moon and beyond, was presumed to have failed in space minutes after lifting off. Saturday's launch was a second test, after its first attempt to reach space ended in an explosion.

In order to reach NASA's safety requirements, SpaceX's HLS system will need to see close to 14 complete successful launches, and those won't be based on SpaceX's metric of "success." They all must be unqualified successes.

Seeing as this is just the third flight of the integrated system, it seems there's a long way to go. 

Not that it's completely out of reach. Musk recently said the company has applied for nine Starship launches in 2024. And SpaceX's Star Base in Boca Chica, Texas, is always a hub of activity with boosters and Starships stacked up in rows.

"The thing that Musk does better than probably anybody else in any industry is to scale up and produce things at scale, in large quantities very quickly," Fjeld said.  

"I think he could easily you know, fly again in two months, and then a month-and-a-half, and then a month later, and then every week for the rest of the year at the end."
