To see Tim Ellis hunched over his laptop, alone in a room at a major space industry conference in Colorado, you can hardly imagine that he might be the next Elon Musk.
Yet Relativity Space, the company he cofounded in December 2015 with the vision of launching 3D-printed rockets, has grown from 14 to 80 employees in one year and is to recruit another 40 this year.
At the age of 28, Ellis has lured several industry veterans, including from Space Exploration Technologies Corp, commonly known as SpaceX, the US market leader for launches that was founded by billionaire entrepreneur Musk.

Relativity Space has raised US$45 million so far, Canadian satellite operator Telesat has entrusted it with the launch of part of its planned 5G satellite constellation and the US military has given it a launch pad at Cape Canaveral.
Ellis, who six years ago was still studying for his masters in aerospace engineering at the University of Southern California, now sits on the US National Space Council along with former astronauts and the heads of the largest US aerospace groups.
“I’m the youngest person by more than 20 years, and we’re the only venture capital backed start-up,” Ellis told reporters during the 35th Space Symposium in Colorado Springs, a major annual event for the space industry that welcomed about 15,000 participants from 40 countries.

Dozens of start-ups have announced plans in the past few years to build small and medium-sized rockets to launch small satellites. Many are likely to fail before having made their first rocket, but that is the game, Ellis said.
“The notion in Silicon Valley is you’re going to take tonnes of big bets, where lots of them will totally lose money, but the ones that succeed will pay for all of the losers — and in a huge outcome, if it’s the next Google or the next SpaceX,” he said.
Relativity Space, which like SpaceX is based in Los Angeles, has so far printed nine rocket engines and three second stages for its rocket model, called Terran 1, whose first test flight is scheduled for the end of next year.
With its large 3D-printing machines, the start-up has said that its rockets should require 100 times fewer parts than traditional rockets.
“We’ll only be experts in like two or three [technological] processes,” compared with traditional manufacturing with complex supply chains, he said. “It’s far easier.”
Only the electronics are not 3D printed.
“It’s much cheaper, because of the labor reduction in the automation with 3D printing,” said Ellis, who plans to charge US$10 million for a launch, at least at first.
“Also, it’s more flexible,” he said, adding that eventually, Relativity Space plans to adapt the size of the fairings of the rockets to the requirements of individual customers, depending on the size of their satellite.
Speed is the other advantage: “Our target is to get from raw material to flight in 60 days,” Ellis said.
If Relativity Space succeeds in this feat — which it has not yet demonstrated — it would revolutionize the launch industry. Today, a satellite operator can wait for years before having a place in the large rockets of Arianespace SA or SpaceX.
The Terran 1 will be 10 times smaller than the SpaceX Falcon 9 and able to place a 1,250kg payload into very low orbit — 185km above the Earth’s surface.
This could be suitable for a constellation of small satellites for telecommunications or imaging the Earth, but also for one of the largest customers in space: the US military.
This is another reason for the young executive’s arrival in Colorado Springs: meeting senior Pentagon officials.
“I rarely wear a suit, but I will for the military,” Ellis said.
Stephen Garrett, a 27-year-old graduate student, always thought he would study in China, but first the country’s restrictive COVID-19 policies made it nearly impossible and now he has other concerns. The cost is one deterrent, but Garrett is more worried about restrictions on academic freedom and the personal risk of being stranded in China. He is not alone. Only about 700 American students are studying at Chinese universities, down from a peak of nearly 25,000 a decade ago, while there are nearly 300,000 Chinese students at US schools. Some young Americans are discouraged from investing their time in China by what they see
MAJOR DROP: CEO Tim Cook, who is visiting Hanoi, pledged the firm was committed to Vietnam after its smartphone shipments declined 9.6% annually in the first quarter Apple Inc yesterday said it would increase spending on suppliers in Vietnam, a key production hub, as CEO Tim Cook arrived in the country for a two-day visit. The iPhone maker announced the news in a statement on its Web site, but gave no details of how much it would spend or where the money would go. Cook is expected to meet programmers, content creators and students during his visit, online newspaper VnExpress reported. The visit comes as US President Joe Biden’s administration seeks to ramp up Vietnam’s role in the global tech supply chain to reduce the US’ dependence on China. Images on
New apartments in Taiwan’s major cities are getting smaller, while old apartments are increasingly occupied by older people, many of whom live alone, government data showed. The phenomenon has to do with sharpening unaffordable property prices and an aging population, property brokers said. Apartments with one bedroom that are two years old or older have gained a noticeable presence in the nation’s six special municipalities as well as Hsinchu county and city in the past five years, Evertrust Rehouse Co (永慶房產集團) found, citing data from the government’s real-price transaction platform. In Taipei, apartments with one bedroom accounted for 19 percent of deals last
US CONSCULTANT: The US Department of Commerce’s Ursula Burns is a rarely seen US government consultant to be put forward to sit on the board, nominated as an independent director Taiwan Semiconductor Manufacturing Co (TSMC, 台積電), the world’s largest contract chipmaker, yesterday nominated 10 candidates for its new board of directors, including Ursula Burns from the US Department of Commerce. It is rare that TSMC has nominated a US government consultant to sit on its board. Burns was nominated as one of seven independent directors. She is vice chair of the department’s Advisory Council on Supply Chain Competitiveness. Burns is to stand for election at TSMC’s annual shareholders’ meeting on June 4 along with the rest of the candidates. TSMC chairman Mark Liu (劉德音) was not on the list after in December last
