Dawn Aerospace is a space transportation company building both in-space propulsion systems and a space launch vehicle. The company currently manufactures satellite propulsion systems with lower greenhouse potential and nontoxic materials, as well as an uncrewed suborbital spaceplane with rapidly reusable flight characteristics.

History

[edit]

Dawn Aerospace was co-founded in 2016 by Stefan Powell (New Zealand), Jeroen Wink (from the Netherlands), James Powell (New Zealand), Tobias Knop (Germany), and Robert Werner (Germany).[citation needed]

In 2018, Dawn Aerospace raised $3.5m in seed funding from New Zealand, American and Dutch investors. Further investment of an undisclosed figure was made in 2021 by Movac and others.[1]

In 2020, Dawn Aerospace successfully performed atmospheric testing of their Dawn MK II spaceplane,[2] verifying its flight characteristics before future 2023 testing of a larger platform.[3]

Satellite propulsion hardware

[edit]

Dawn Aerospace currently produces hardware for small satellites, to include thrusters and propellants.[4]

Dawn aerospace has provided the propulsion to Pixxel, an Indian based space organization.[5] They also have signed contracts with the ESA, [6] contracts with Blue Canyon, now part of Raytheon Technologies, to provide its proprietary mix of propellants for microsatelite operations [7][8] and ALE Co., Ltd. Japan and UARX Space. In the last case Dawn provided them with its own proprietary propulsion architecture.[9][10][11] Dawn Aerospace has also signed contracts with Indonesia's national space agency, working to provide the propellant for a new satellite network dedicated to providing early warning of tsunami and earthquake related phenomena.[12][13]

B20 Thruster

[edit]

Dawn Aerospace's B20 thruster is a 20 newton thruster that uses a chemical propellant made up of nitrous oxide and propylene. The innovation is that it replaces hydrazine, a highly toxic chemical compound often used in satellites. This allows for quicker launches and more safe handling of the rocket while on the ground, increasing launch cadence.[14] In 2021, D-Orbit, a space logicists firm, validated the thrusters on its PULSE space tug mission, firing six B20 thrusters.[15][16]

B1 thruster

[edit]

Another in-space propulsion rocket motor, the B1 thruster is a 1 newton thruster for satellites. It is manufactured as a single structure using Inconel 718. In 2021 it was flown on the Hiber-Three and Hiber-Four 3U CubeSat, which were respectively launched by Soyuz-2 and Falcon9 on the SpaceX Transporter-1 mission,[17] SpaceX's first dedicated SmallSat Rideshare program mission.[18]

Dawn Mk-II Aurora spaceplane

[edit]

Dawn Aerospace unveiled [19] the Mk-II Aurora uncrewed suborbital spaceplane in July 2020.[20] With 100 per cent hardware recovery and same-day flight capabilities, the Mk-II Aurora is a reusable vehicle that has demonstrated more than 48 flights, below 9000 ft altitude, using jet engines.[21] In 2021, the Mk-II Aurora flew for the first time during five test flights over the South Island of New Zealand between 28 and 30 July.

On 9 December 2021, Dawn Aerospace announced it had received a license to fly its suborbital spaceplane from a conventional New Zealand Airport, working with the Civil Aviation Authority of New Zealand (CAA) and New Zealand Space Agency.[22][23]

Dawn Aerospace has conducted 48 successful tests using jet engines to prove their spaceplane platform,[24] verifying its flight characteristics before future 2023 testing of a larger platform.[25]

In March 2023, the CAA certified the craft for rocket-powered (HTP/kerosene) test flights.[26] The first three rocket-powered test flights were conducted[clarification needed] between 29 and 31 March 2023 from Glentanner Aerodrome.[27] Subsequent certification for supersonic flight was received from the CAA in July 2024.[28]

Facilities

[edit]

Dawn Aerospace operates from three global bases: one each in the Netherlands, New Zealand, and the United States. Dawn Aerospace's headquarters are in Christchurch, New Zealand. They placed it there due to it being a good location for flight testing with less air traffic and stable weather. Dawn Aerospace is registered in New Zealand.[29][30]
