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

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.

Radian raises $27.5 million to develop single-stage-to-orbit spaceplane

Capitalism in space: The startup Radian Aerospace announced yesterday that it has raised $27.5 million in private investment capital to fund the development of a single-stage-to-orbit spaceplane it dubs Radian One.

Radian has disclosed few technical details about the Radian One design. The seed round “essentially helps us transition more robustly into the hardware development phase,” Holder said. The company’s work to date has focused on the conceptual design and a few key technologies, such as test-firing “critical elements” of the vehicle’s main propulsion system.

The company said it has launch service agreements for Radian One with commercial space station developers, in-space manufacturers, satellite, and cargo companies, as well as agreements with the U.S. government and selected foreign governments. It did not identify specific customers, value of any such agreements or schedules for delivering those launch services.

Company officials seem confident they can do this. Their chief technology officer worked on the failed 1990s single-stage-to-orbit X-33 project, and is convinced the advances in technology since now make such a spaceplane possible.

We shall see. Radian faces stiff competition, as it is one of more than a hundred new orbital rocket companies. Its advantage, if successful, is its completely reusable airplane-like design.

India test flies its first spaceplane prototype

The competition heats up: India this morning successfully completed a test flight of its first spaceplane engineering prototype.

After a 90sec burn, the booster delivered the RLV-TD to the proper altitude before separating from the prototype and destructively fall back to Earth in the Bay of Bengal. Meanwhile, the RLV-TD continued on, falling back into Earth’s atmosphere at hypersonic velocity. During this hypersonic test, the RLV-TD pitched its nose up relative to the horizon and direction of travel – just as the Space Shuttles did during atmospheric entry. This allowed engineers to gather valuable in-flight data surrounding the performance of the vehicle’s thermal protection system (600 heat-resistant tiles and a carbon-carbon nose), its aerodynamic characteristics during hypersonic flight, and inform the overall design of the eventual full-scale RLV.

The prototype was designed to test the flight characteristics of the spaceplane, not its landing capabilities. If all went as planned, it would have glided horizontally into the ocean, as if it was landing on a runway, but then sink.

Phase 2 begins in DARPA spaceplane program

The competition heats up: DARPA is about to start asking for proposals for the second phase of its XS-1 spaceplane program.

In Phase 1 of XS-1, DARPA sought to evaluate the technical feasibility and methods for achieving the program’s goals. To achieve that, it awarded prime contracts to three companies, each working in concert with a commercial launch provider: The Boeing Company (working with Blue Origin, LLC); Masten Space Systems (working with XCOR Aerospace); and Northrop Grumman Corporation (working with Virgin Galactic). Phases 2 and 3 will be competed as a full and open Program Solicitation mandating an Other Transaction Authority (OTA) agreement with the expectation of a single resulting award. Cost share is expected.

The primary goal is to build a vehicle that can fly ten times in ten days and put a small satellite into orbit.

India’s spaceplane prototype to fly by August

The competition heats up: The first test flight of India’s prototype scaled-down version of a reusable spaceplane is expected by late July or early August at the latest.

It appears the Modi government is accelerating development of this mini-shuttle, which is essentially India’s version of Sierra Nevada’s Dream Chaser. If they build it first, it will mean they will have the chance to grab the business that Sierra Nevada has been hoping to grab.

Test flight of European space plane delayed

The November suborbital test flight of Europe’s Intermediate eXperimental Vehicle (IXV) has been delayed to allow additional preparation.

For this mission, instead of heading north into a polar orbit, as on previous flights, Vega will head eastwards to release the spaceplane into a suborbital path reaching all the way to the Pacific Ocean to test new technologies for future autonomous controlled reentry for return missions. This trajectory is unprecedented for Vega and therefore more information is being generated on the performance of the launch vehicle, should an anomaly occur after liftoff.

ESA will not only be testing the flight characteristics of the space plane, they will be testing their new Vega rocket, which has only been launched a handful of times.
