Dawn Aerospace begins offering its suborbital spaceplane to customers

12:15 pm

Though the company has only so far flown a small prototype on low altitude supersonic test flights, the spaceplane startup Dawn Aerospace is now taking orders for those who wish to put payloads on its proposed Aurora suborbital spaceplane, targeting a first flight in late 2026.

Dawn Aerospace is taking orders now for the Aurora spaceplane for deliveries starting in 2027. The company has not disclosed pricing for the vehicle, and [CEA Stefan] Powell suggested the company would tailor pricing to each customer. He said that the company estimates, based on market research, that a per-flight price of $100,000 is “absolutely tenable,” and the price could go higher for missions with more customized flight needs. He projects Aurora could fly 100 times a year and has a design life of 1,000 flights, with a total revenue per vehicle of about $100 million.

Though the company had originally touted itself as developing an orbital spaceplane, it recently shifted its goals, at least for the present, to building a very powerful jet comparable in some ways to the X-15, capable of reaching altitudes exceeding 50 miles for short periods and short periods of weightlessness. This capability has some value, and Dawn Aerospace has decided to market it for profit, rather than wait for the orbital version that might be years away.

Dawn Aerospace small-scale rocket-powered airplane breaks the sound barrier

On November 12, 2024, the startup Dawn Aerospace for the first time flew its small-scale rocket-powered Mk-II Aurora unmanned airplane at speeds exceeding the speed of sound, becoming the first commercial airplane since the Concorde to break the sound barrier.

The company, operating as Dawn Hypersonics, achieved the milestone on 12 November 2024, with the Aurora surpassing the speed of sound for the first time, reaching Mach 1.1 and climbing to an altitude of 82,500 feet. This is over twice as high as commercial aircraft and marks the first time a civil aircraft has flown supersonic since Concorde. This achievement signifies a major step toward operational hypersonic travel and daily space access, establishing rocket-powered aircraft as a new class of ultra-high-performance vehicles.

The flight, conducted from New Zealand’s Glentanner Aerodrome near the base of Aoraki Mt Cook, exceeded its test target speeds and altitude of Mach 1.05 and 75,000 feet. The Aurora also set a global record, becoming the fastest aircraft to climb from ground level to 20 km (66,000 feet), completing the ascent in just 118.6 seconds. This beats the previous record, held by a highly modified F-15 ‘Streak Eagle’ in the 1970s, by 4.2 seconds.

It appears the company’s goals have changed and become less ambitious, at least for the moment. According to the company’s press materials now, the goal now is to sell Mk-II (and bigger versions) for suborbital hypersonic research, both for the military and private sector. Back in 2021 however the company described Mk-II as merely a preliminary test vehicle leading to the construction of a larger fullscale two-stage-to-orbit version that would take off and land on a runway and could be used to launch satellites to orbit.

In a sense, nothing might have really changed, other than the company realizing that it should try to make money on the Mk-II now, even as it flies and tests it in preparation for eventually building the larger orbital version. If Dawn begins to win contracts using this prototype, it will then have the resources (as well as the ability to raise more investment capital) to advance to larger more powerful version.

Dawn Aerospace completes new round of flight tests of its small-scale rocket-powered airplane

The space startup Dawn Aerospace on August 7, 2024 announced the successful completion of a second set of flight tests of its small-scale rocket-powered Mk-II Aurora airplane, reaching speeds just below the speed of sound, with the goal in the next round of flights to set several major records and lay the groundwork of building a reuseable orbital spaceplane that can launch and land on a runway, and do so twice in one day.

The campaign (dubbed Campaign 2-2) saw three flights completed in late July. In flight three, we achieved a maximum speed and altitude of Mach 0.92 (967 km/h) and 50,000ft (15.1km). That is 3x and 5x of what we had achieved in the previous campaign – a massive jump in demonstrated performance.

We are now poised to fly supersonic in Campaign 2-3, scheduled for September. But that is just the beginning. In many respects, the Mk-II is slated to be the highest-performance vehicle to take off from a runway. By the end of 2025, we’re looking to climb faster than an F15, fly higher than a Mig 25, faster than an SR-71, and, ultimately, be the first vehicle to fly above the Karman line; 100km altitude (the generally accepted definition of “space”), twice in a single day.

Some of these records have stood for over 50 years.

The company has so far spent $10 million on this project, and has raised a total of $20 million. Nor is this Dawn’s only effort. It builds and sells thrusters for smallsats, and is also selling to smallsat makers its own docking and refueling port.

The press release at the link is very detailed, and worth perusing. Four of the company’s founders come from the rocket field, with the fifth from aviation. Their goal, to build from scratch a commercial orbital spaceplane using private funds entirely, is quite laudible but incredibly challenging. It remains to be seen whether they can do it. That the company has diversified successfully into the satellite industry is very encouraging however.

Spaceplane startup flies small-scale prototype for the 1st time using new rocket engine

9:31 am

The startup Dawn Aerospace, based in New Zealand, has now successfully flown a small-scale prototype of its proposed spaceplane using for the first time the company’s Aurora rocket engine.

Mk-II Aurora, a scaled down version of the spaceplane Dawn is developing for commercial operations, took to the skies March 29, 30 and 31 from New Zealand’s Gentanner Aerodrome. The initial test campaign validated key flight systems and demonstrated the benefit of rapid reusability, Dawn CEO Stefan Powell told SpaceNews.

During the first flight, the Mk-II Aurora consumed more fuel than anticipated due to a leak in the propellant system. The next day, Dawn engineers removed the Mk-II Aurora engine, took out the oxidizer tank and found the leak.

These rocket-powered test flights are a follow-up of an earlier test program in 2021 using jet engines. You can get a sense of the scale of the prototype from a picture at this article.

The company plans to fly this prototype to as high as twelve miles later this year before moving on to a larger test version. Eventually it hopes to develop a two-stage orbital system. The details however remain vague. The 2021 release suggested it was building a two-stage-to orbit version that will take off from a runway and then launch small satellites into orbit. These new stories suggest it are presently targeting the suborbital unmanned research market, with the eventual ability to do frequent flights to 70 miles altitude. Launching orbital satellites is presently only a distant goal.

Prototype of reusable suborbital spaceplane from new startup completes five flights

10:40 am

Capitalism in space: Another rocket startup company, Dawn Aerospace, has completed a five flight test program of a prototype of its proposed reusable suborbital spaceplane, dubbed Aurora.

Dawn Aerospace has successfully completed five test flights of its uncrewed Mk-II Aurora suborbital spaceplane in the skies over Glentanner Aerodrome on New Zealand’s South Island. The flights were conducted by the New Zealand-Dutch space transportation company from July 28 to 30, 2021 at altitudes of up to 3,400 feet (1,036 m), with the prototype airframe fitted with surrogate jet engines.

The three-days of test flights to assess the airframe and avionics of the aircraft took place under a certificate issued to Dawn by the New Zealand Civil Aviation Authority (CAA), which allowed the Mk-II Aurora to operate from conventional airports without airspace restrictions after ground tests were completed.

The company claims this is a demonstrator for their fullscale two-stage-to orbit version that will take off from a runway and then launch small satellites into orbit.

Looks impressive, but my impression of this prototype is that it is a small scale model, only slightly more sophisticated and larger than a model airplane. That impression is reinforced by the video at the link, which provides no visible markers to judge size.

This company needs to get a lot more done if it wants to compete in this new market.
