3D-printed Relativity Space rocket fails shortly after launch

The Terran 1 rocket, designed and built by Relativity Space, crashed shortly after liftoff from a launch pad in Cape Canaveral, Florida, late Wednesday night. Demonstration mission, the rocket carried no people or customer payload, no one was hurt.

The vehicle was equipped with nine 3D printed engines and was supposed to be the first rocket launched into orbit using liquid methane as fuel. During a flight webcast on Wednesday, the rocket rose on a plume of white flame that flashed blue as it shot into space.

But about four minutes into the flight, shortly after the rocket’s first stage fell, Clay Walker, launch director for Relativity Space, said on the company’s webcast that there had been a “T-plus anomaly with the second stage,” meaning the problem with the second stage of the rocket, which was supposed to put the payload into orbit.

The company’s webcast hosts said more details about the issue would be announced at a later date.

After the success of Elon Musk’s SpaceX, investors poured money into new space companies. Some of these companies have interplanetary ambitions, including Relativity Space, which announced last year that it would team up with another company called Impulse Space to send a private space mission to Mars, aiming to outdo Mr. Musk’s company on the red planet. .

But many nascent space companies struggle in their first attempts at orbit. In January, the Virgin Orbit spacecraft failed after an hour of flight; company since then fired employees. another company ABL space systems, lost its first missile immediately after launch from a base in Alaska. And even experienced rocket scientists lose new rockets on their first flight. Earlier this month, a new rocket built for the Japanese space agency by Mitsubishi Heavy Industries, which has been making rockets for decades, failed minutes after its first flight and lost the satellite it was supposed to launch.

The Relativity flight on Wednesday did not lose a client satellite. The only payload was a wheel-shaped object, the first ever produced by Relativity’s 3D printers, to demonstrate the rocket’s ability to launch a payload into orbit.

The flight, which the company has dubbed Good Luck, Have Fun, or GLHF, was the company’s third launch attempt in the past two weeks. The previous two were canceled due to a number of technical problems shortly before the start.

During the launch on Wednesday, the company marked some milestones reached by rocket. This was the first time that a 3D printed rocket reached “max-q”, the point where the booster experiences the heaviest loads, as well as the stage separation when the booster used for launch is dropped from the second stage of the rocket – carrier.

Relativity Space is among new companies building and testing low-lift launch vehicles: rockets that can carry a smaller payload of about two tons or less, typically with a destination in low Earth orbit.

The 110-foot-tall Terran 1 falls into this “small launcher” category and is planned as a precursor to the much larger Terran R reusable launcher, which the company hopes to begin testing soon.

To make these rockets, Relativity Space has developed massive 3D printers in Long Beach, California that use robotic arms to make engines and other metal alloy parts that can withstand the heat and pressure of burning rocket fuel.

Traditional manufacturing processes often slow down the construction of rockets. But 3D printers, which turn code into physical objects, allow engineers to move from design to testing faster. Instead of creating an entirely new part, engineers can simply tell printers to increase the size of existing parts or modify them in other ways.

Because of this, modern rockets have a lot of 3D printed parts. But Relativity Space treats 3D printers as a one-stop-shop for almost all of its rockets. About 85 percent of the Terran 1’s mass was 3D printed, and each rocket can be made from nothing in 60 days.

Relativity is among several companies building orbital launch rockets using liquid oxygen and liquid methane as fuel. In the past, most rockets used hydrogen or kerosene as fuel. Methane is the main component of liquefied gas – it is easier to store than hydrogen and has higher performance than kerosene. Starship, the next-generation rocket that SpaceX is building to fly to the Moon and Mars, will use a similar fuel.

Carissa Christensen, founder and CEO of space analytics firm BryceTech, noted that of the hundreds of space startups created in recent years, only a few have made it to the launch pad. This alone sets Relativity Space apart from many other private companies looking to launch rockets. It shows “something like proof of an investment thesis,” Ms. Christensen said in an interview earlier this month.

A launch attempt, successful or not, is what Ms. Christensen celebrates.

“This is a step towards creating a complex engineering system,” she said of the Terran 1 flight. “Success or failure, they learn something.”

Positive Grid Introduces Spark Go Ultra-Portable Enhanced Guitar Amplifier

Positive Grid has a new ultra-portable version of its high-tech Spark guitar amp. Designed for musicians who need a versatile and powerful practice amp, the 3.5″ tall Spark Go works with a companion app loaded with virtual amps, pedals and other effects, and can even flesh out your sound with AI drums and other accompaniments. tools.

Like its predecessors, Spark Go is paired with an iOS/Android app to go far beyond enhancing your strumming and gaming; it digitally enlarges it. It includes 50,000 tones (ranging from boutique to modern), 33 amps and 43 effects and pedals, giving you many new ways to shape your sound. The app can even “jam with you” by listening to your playing and learning from it by creating an appropriate background track. And if you want to learn new tunes, the app can sync with Spotify or Apple Music to display AI-generated chords for the song you hear.

A 2021 review of the Spark Pearl (a larger model in the same line) by Engadget found the app to have some rough edges, including an unconvincing AI drummer. However, the company has had plenty of time to iron this out, so we reserve the right to judge the current iteration until we test it again. After all, you may have heard that generative AI has made some impressive leaps since then.

The amplifier has a solid construction and “extra hard grille” to (at least in theory) live up to its “on the go” brand; Positive Grid says it’s even suitable for pedalboarding. The company suggests laying it flat for omnidirectional sound, or placing it on the edge for “sound in the face.” In addition, it uses computational audio that delivers “surprisingly big, full sound” from its tiny body. (And you can plug in headphones to practice in private.) The amp’s battery supposedly lasts up to eight hours and charges via USB-C. Finally, it supports four presets when you find a mix you want to keep close at hand.

Positive Grid accepts early registration to be notified when Spark Go pre-orders go live. Whenever they open (the company hasn’t announced a date yet), the company will offer the amplifier at an aggressive $109 price point, although it will eventually increase to the recommended $149.
