Watch this awesome boost-back burn on a returning SpaceX rocket

The critical process paves the way for the booster's safe return to Earth so that it can be used again.

SpaceX launched an unmanned, robotic spaceplane to orbit for the U.S. Space Force in the USSF-36 mission on Thursday night. 

The Falcon 9 carrying the spaceplane lifted off from the Kennedy Space Center in Florida shortly before midnight, with the rocket’s night flight producing a dazzling fireworks show immediately after stage separation.

The moment was captured by news outlet NASASpaceflight and shared on social media. Stick with it, as things really kick off just past the 20-second mark (in the bottom video).

The dramatic footage clearly shows the boost-back burn of the Falcon 9 rocket’s first stage.

The spectacular “Falcon 9 nebula” — so called because of its similarity to the colorful gaseous clouds in deep space — is created by the boost-back burn’s exhaust plume as three of the rocket’s nine Merlin engines briefly reignite high in Earth’s atmosphere.

The maneuver takes place just after the booster separates from the upper-stage carrying the payload, in this case the spaceplane. The critical process initiates the booster’s return to the landing site around five minutes later.

Bringing the first-stage booster back to Earth and landing it upright back at the launch site, or on a droneship in the ocean, allows SpaceX to reuse the vehicle multiple times, saving on costs and enabling a higher launch frequency.

The Falcon 9 left the launchpad at 11:50 p.m. ET on Thursday in the sixth flight for this particular first-stage booster, which previously launched NROL-69, CRS-32, GPS III-7, and two Starlink missions. The booster landed safely back at Cape Canaveral, Florida.

The USSF-36 mission marked the eighth launch of NASA’s X-37B Orbital Test Vehicle (OTV-8) and the third Falcon 9 launch of the spacecraft, after SpaceX previously launched OTV-5 and OTV-7 (USSF-52).

The commercial spaceflight company is set for a big day on Sunday when it launches the massive Starship rocket for the 10th time. If you’re interested in witnessing what promises to be another breathtaking launch, Digital Trends has all the information you need.

After 13 suborbital test flights and more than $15 billion in development costs, SpaceX's Starship has finally reached orbit. The 407-foot megarocket, the most powerful ever built, lifted off from Starbase, Texas, on Monday and delivered its first real payload on it's 14th attempt. The celebration came with an asterisk, though, since SpaceX had to cut the planned 10-hour mission to roughly three hours.

Starship is finally going orbital, and SpaceX has picked September 22
Flight 14 is aiming for orbit, Starlink V3 deployment and a very long day in space.

SpaceX is finally ready to give Starship its biggest test yet. The company says the massive rocket's 14th test flight is scheduled for September 22, when it will attempt to put the upper stage into Earth orbit for the first time. The launch is currently pending regulatory approval, with a 75-minute window opening at 7:15 a.m. CT.

Want a city on the Moon? Scientists say there’s not enough water
A billion tons still comes up short

For decades, humanity has looked up at the Moon and wondered what it would be like to live on it. Think sprawling cities, factories, research centers, and permanent human settlements. Unfortunately, there is one fairly fundamental problem with that vision.

A new study published in Frontiers in Space Technologies argues that even the Moon's potentially enormous reserves of frozen water may be nowhere near enough to support city-sized populations sustainably. Researchers Martin Elvis and Jonathan McDowell estimate that the permanently shadowed regions near the lunar poles could contain roughly one billion tons of water. It sounds like an extraordinary amount until you put a million thirsty humans next to it.
