Rocket startup Radian now also building commercial reentry capsule

The rocket startup Radian Aerospace, which is attempting to build an orbital spaceplane that takes off and lands from a runway, has announced that it is also building a commercial reentry capsule that can be used for hypersonic testing.

The Seattle based company announced April 29 its intent to develop the Radian Reusable Reentry Vehicle (R3V), a spacecraft for hypersonics testing or returning payloads from space that also gives Radian flight experience in key technologies for its future Radian One spaceplane.

Livingston Holder, chief technology officer of Radian, said in an interview that the company was looking was ways to test Dur-E-Therm, the thermal protection system it is creating for Radian One. The company had recently completed tests of the system in a lab at NASA’s Glenn Research Center. “But, testing in a non-flight environment only gets you so far, so we were crafting how to test it in a more relevant environment.”

It appears the company has recognized that its spaceplane will take years to develop, and more years before it can bring in any revenue. An orbital capsule however can be developed much more quickly, and it also appears there are a lot of commercial and military customers for it.

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.
