Multinational space transportation company Dawn Aerospace has released previously unavailable footage of its enigmatic Aurora Spaceplane carrying a “data acquisition payload” for the Johns Hopkins Applied Physics Laboratory (APL).
According to an email from the company, the flight reached an altitude of 62,000 feet, demonstrating Aurora’s ability to achieve suborbital altitudes at a significantly lower cost than other commercial launch options.
Dawn Aerospace also noted that flights like the John Hopkins APL payload help them gain real-world experience for their full-performance Aurora spaceplane, which is already in production, capable of achieving Mach 3.7 and altitudes exceeding 328,000 feet.
Record-Setting Aurora Spaceplane is Remotely Piloted
In that same announcement, the company noted that Johns Hopkins APL is a leading U.S. research organization with projects spanning the civil and defense communities, adding, “It’s an honor to have them fly with Dawn!”
Although few details about the actual payload were available at the time of the video’s release, the company noted that reaching the 62,000-ft ceiling represents only a fraction of the fully operational Aurora Spaceplane’s capabilities.
For example, Aurora made its first rocket-powered flight in April 2023, then broke the sound barrier in November, 2024, reaching Mach 1.12 at 82,500 feet. The craft also set a record for the fastest climb to 20 kilometers (65,600 feet), besting the previous record set in 1975 by what the company termed a “modified” F-15 Streak Eagle.
Unlike other proposed or operational high-Mach vehicles, the Aurora is remotely piloted, eliminating the need for onboard life support systems.
Space Payloads Over 100 Km Achieve Over 2 Minutes of Microgravity
According to the company’s website, Aurora is designed for suborbital space access missions that maximize the amount of time the vehicle and its payloads spend in microgravity. Dawn also noted that extended periods at altitudes above 100 kilometers (62.5 miles) can dramatically increase “pointing time” for optical payloads.
For space payloads targeted at altitudes above 100km, the company says a typical flight time is around 30 minutes. Although microgravity durations may vary by mission type, the company said Aurora can achieve a maximum of 127 seconds.
“When flying the Suborbital profile, Aurora can provide up to two minutes of altered gravity environments,” the company explains. “These environments include microgravity, lunar gravity and Martian gravity, achieved by varying Aurora’s rotation rate.”
For optical payloads, the company said that Aurora can be “oriented and held at a fixed attitude,” depending on the mission profile. For missions within the atmosphere, the company notes that the Aurra Spaceplane’s boost-glide profile is optimized to “reach high Mach numbers within the atmosphere for supersonic and target presentation use-cases.”
Like the space launch profile, boost-glide missions can reach speeds of Mach 5.7 and perform what the company described as “a range of maneuvers in the supersonic regime.”
Hybrid Design includes Rocket Engine and Airplane Control Surfaces
Part of a new generation of hybrid aircraft, Aurora is powered by a restartable rocket engine rather than an air-breathing engine like an airplane’s, allowing it to reach orbit and operate there.
However, the sci-fi-looking craft employs conventional aerodynamic control surfaces for in-atmosphere control. When operating above the atmosphere, the company notes that Aurora has an “independent reaction control system” that provides the remote pilot with full attitude control.
The craft’s airframe is made from high-strength, lightweight composites capable of enduring repeated, high-G flights. The company said Aurora is also equipped with onboard data acquisition, enabling “full in-flight monitoring of vehicle and payload performance.”
During atmospheric or above-atmosphere operations, Dawn Aerospace’s Aurora Spaceplane houses payloads within a dedicated cargo bay. The company notes that the bay is “designed for modular integration, with defined mass, volume, and power envelopes,” thereby accommodating a wide range of possible missions.
Making High-Speed, High-Altitude Flight a Routine
Although the Johns Hopkins APL launch was a single mission with a designated payload, the company said that one of the key benefits of their platform, beyond its cost, is its rapid repeatability and turnaround, including the ability to enable frequent suborbital flights from a conventional aircraft runway rather than custom-built runways or dedicated rocket launch facilities.
While neither the company nor their customers offered further details on the successfully launched mission, the company says their platform’s capabilities are designed for atmospheric science research missions, microgravity research and manufacturing, and Space technology development and qualification.
“Our flight operations team works alongside you from mission design through to flight operations.”
The Aurora Spaceplane is currently a commercial flight testing and launch platform. However, the company’s website notes that the craft could be configured for “defense and domain awareness applications.”
“By combining the performance of a rocket with the reliability and versatility of an aircraft, Aurora makes high-altitude and high-speed flight a routine, repeatable part of your program,” the company’s site explains. “In turn, helping you to test, iterate, and demonstrate faster.”
