Super Strypi (also SPARK for Space-borne Payload Assist Rocket - Kauai ) is a US American launch vehicle project for small payloads. So far, there has only been one flight in which the rocket broke on November 4, 2015 about one minute after takeoff.
Development and operator
The Super Strypi is a successor to the suborbital rocket Strypi and was developed like this by Sandia National Laboratories . The University of Hawaii was initially responsible for the launch and the payload . Today, the rocket is marketed by X-Bow Launch Systems , a company founded in 2016 and based in Huntsville , Alabama .
The development of the missile was funded by the US Department of Defense . X-Bow has been a participant in the US Air Force's OSP-4 program ( Orbital Services Program-4 ) since 2019 . This program will provide almost one billion US dollars for the launch of small military satellites over a period of nine years .
Structure and use
All three stages of the Super Strypi use solid propulsion systems newly developed by Aerojet Rocketdyne . The first stage has a LEO-46 engine. The second stage is powered by a LEO-7 and the third stage uses a LEO-1 engine. The rocket is spin stabilized during its flight .
The planned takeoff weight of the launch vehicle is around 28,200 kg. A modified Scout launch tower is used for the launch , in which the rocket is inclined at about 75 ° and is guided on rails during the launch phase. The burning times of the three stages should be around 79, 62 and 51 seconds, which should enable a payload of around 250 kg to be transported into an orbit at a height of around 400 km.
Starts
The only launch so far was on November 4, 2015 at 03:45 UTC from the Kokole Point Launch Pad of the Kauai Test Facility (Barking Sands) in Hawaii . A total of six small satellites were to be brought into low-earth orbit :
| payload | Type of payload | Dimensions |
|---|---|---|
 HiakaSat (HawaiiSat 1) Supernova-Beta Argus (SLU 02) PrintSat EDSN 1-8 STACEM

However, the rocket tumbled and broke about a minute after launch.
A second start was already planned back then. At the beginning of 2017, X-Bow named 2018 as the start period and announced a third start for 2019.
