Most weeklong tech events have opportunities for entrepreneurs to make contacts and trade tips, serious sessions where CEOs and public officials share their visions, and happy hours where future deals are made. But how many “tech weeks” include a show-and-tell featuring a military-grade Jet Gun?

That was one of the bonus attractions during Seattle Space Week, a smorgasbord of events served up by Space Northwest and its partners.

Just as attendees were sitting down for Monday’s opening session at the Pioneer Building in the heart of Pioneer Square, team members from Wave Motion Launch Corp. parked a box truck just outside the building and opened up the back to reveal the prototype jet blaster they’re testing for the U.S. Army.

Two of the Everett, Wash.-based startup’s co-founders, CEO Finn van Donkelaar and chief operating officer James Penna, stood in the truck and explained their project to a crowd that gathered around on the sidewalk.

Kent, Wash.-based New Frontier Aerospace says it has put its 3D-printed Mjölnir rocket engine through a series of successful hot-fire tests, in preparation for an initial flight test of a hypersonic drone that could take place as early as next year.

Mjölnir is named after the hammer that was wielded by Thor in Norse mythology (and in Marvel movies). The first job for this hammer would be to propel an uncrewed aerial system called Pathfinder for a series of hovering tests, currently set for 2026. Eventually, Pathfinder could be used for weapons testing or for suborbital point-to-point cargo transport.

The engine is also slated for use on New Frontier’s Bifröst orbital transfer spacecraft, which is due to fly into space by 2027. (Continuing with the Norse mythology theme, Bifröst was the rainbow bridge that connected the realm of humans with the realm of the gods.) Mjölnir, which is fueled by liquid natural gas, will also be marketed to other aerospace ventures as a standalone product.

Seattle-based Radian Aerospace says it’s developing a reusable re-entry vehicle that can be used to test aerospace components under stressful conditions and then bring them back down to Earth.

The Radian Reusable Re-entry Vehicle, or R3V, is meant to advance technologies that the company is building into Radian One, its single-stage-to-orbit spaceplane.

Radian says the insights gained from R3V’s uncrewed test flights will inform critical elements of the Radian One mission platform, including aerodynamic performance, guidance and control, and the operability of subsystems such as propulsion and thermal protection.

For example, R3V will use Dur-E-Therm, a thermal protection material that Radian invented to withstand the stresses of atmospheric re-entry at hypersonic speeds.

R3V is under development in the Seattle area and could be ready for its first flight by early 2026, Radian says. In addition to blazing a trail for the spaceplane, R3V is expected to generate near-term revenue.

Chalk up another milestone for Stratolaunch, the air-launch venture created by the late Microsoft co-founder Paul Allen: The company’s mammoth airplane deployed a winged test vehicle for its first rocket-powered flight.

Stratolaunch’s single-use TA-1 test vehicle blazed a trail for future reusable hypersonic test vehicles that are expected to help the U.S. military catch up on one of the frontiers of aerial combat. TA-1 went supersonic, according to Zachary Krevor, Stratolaunch’s president and CEO — but based on his comments, it may not have quite hit the hypersonic standard of five times the speed of sound.

“While I can’t share the specific altitude and speed TA-1 reached due to proprietary agreements with our customers, we are pleased to share that in addition to meeting all primary and customer objectives of the flight, we reached high supersonic speeds approaching Mach 5 and collected a great amount of data at an incredible value to our customers,” Krevor said today in a news release.

TUKWILA, Wash. — Thirty years after the first flight of a pioneering reusable rocket ship known as the Delta Clipper Experimental, or DC-X, a commercial venture is aiming to bring its legacy to life in the Seattle area. Even its name — New Frontier Aerospace — is a callback to the earlier days of America’s space effort, going back to John F. Kennedy references to outer space as part of his “New Frontier.”

“We’re sort of like the grandson of DC-X,” New Frontier’s co-founder and CEO, Bill “Burners” Bruner, said at the startup’s headquarters in Tukwila.

But he doesn’t see New Frontier as a space launch venture in the strictest sense of the word. “We’re not doing the squat, or cylindrical or conical shapes that we were talking about in those days,” he told me. “We’re proposing to combine the hypersonic research of the ’50s, ’60s and ’70s, and some of those geometries, with reusable rockets to attack the trillion-dollar air transportation market instead of the $11 billion space launch market.”

Stratolaunch hits milestone in its hypersonic quest

California-based Stratolaunch, the venture created by the late Microsoft co-founder Paul Allen, released a separation test vehicle for the first time this weekend during an experimental flight of the world’s largest airplane.

The event marked a significant milestone in Stratolaunch’s quest to create an air-launch system for rocket-powered hypersonic vehicles.

The May 13 outing was the 11th flight test for Stratolaunch’s flying launch pad — a twin-fuselage, six-engine airplane with a record-setting 385-foot wingspan. The plane is nicknamed Roc in honor of a giant bird in Middle East mythology.

Roc carried the Talon-A separation test vehicle, known as TA-0, during three previous test flights. But this was the first time TA-0 was released from Roc’s center-wing pylon to fly free. The release took place during a four-hour, eight-minute flight that involved operations in Vandenberg Space Force Base’s Western Range, off California’s central coast.

Stratolaunch, the air-launch company founded by the late Seattle software billionaire Paul Allen, today conducted its second captive-carry test flight with the world’s largest airplane and a piggyback payload. The six-hour outing from California’s Mojave Air and Space Port marked further progress toward the first launch of the Talon-A hypersonic flight vehicle.

Today’s flight gave Stratolaunch’s team a chance to rehearse procedures for releasing a separation test vehicle from the twin-fuselage Roc aircraft in midflight — and eventually launching rocket-powered Talon-A vehicles for government and commercial applications. “We are excited for what’s ahead this year as we bring out hypersonic flight test service online for our customers and the nation,” Stratolaunch CEO Zachary Krevor said in a news release.

Stratolaunch, the company created by Microsoft co-founder Paul Allen more than a decade ago, says it’s won a contract from the U.S. Air Force Research Laboratory to support next year’s flight test of Stratolaunch’s first Talon-A hypersonic vehicle.

The rocket-powered Talon-A is designed to be deployed from Stratolaunch’s twin-fuselage Roc aircraft, which is the world’s largest airplane. Last month, Stratolaunch flew a stand-in for the hypersonic test vehicle during Roc’s eighth flight test, and it’s planning to execute Roc’s first air launch with TA-1 in the first quarter of 2023.

Stratolaunch — the air-launch company founded by the late Seattle software billionaire Paul Allen — put a test version of its hypersonic vehicle through its first in-the-air trial today.

The Talon-A separation test vehicle, known as TA-0, stayed firmly attached to its Roc carrier airplane throughout today’s five-hour outing, which began and ended at California’s Mojave Air and Space Port. This was Roc’s eighth flight test, but the first to have a payload attached to a wing pylon centered between its twin fuselages. Roc rates as the world’s largest airplane, with a wingspan of 385 feet.

This time, Stratolaunch focused on measuring the aerodynamic loads on the Talon-A test vehicle while mated to Roc, in preparation for future tests that would involve releasing a functional, rocket-equipped Talon-A for hypersonic flight.

Roc reached a maximum altitude of 23,000 feet and a speed of 185 knots (213 mph) during the flight test, Stratolaunch CEO Zachary Krevor said.

Stratolaunch says its mammoth carrier airplane rose to its highest altitude yet during its seventh flight test over California’s Mojave Desert.

The aerospace venture, which was established by Microsoft co-founder Paul Allen more than a decade ago but is now owned by a private equity firm, reported a peak altitude of 27,000 feet during today’s test.

If all goes according to plan, the twin-fuselage Roc airplane could begin flying Stratolaunch’s Talon-A hypersonic test vehicles for captive-carry and separation testing as early as this year.

One of the prime objectives for today’s three-hour flight at the Mojave Air and Space Port was to gather data on the aerodynamic characteristics of the plane, including a pylon structure from which the rocket-powered Talon-A vehicles will be released and launched.

Roc’s seventh flight came a week after the sixth flight test, which couldn’t achieve all of its objectives.
