Haas is a family of rocket space launchers developed by the ARCAspace for the Google Lunar X Prize competition and for their national manned space program. no rocket has been launched, the planned rocket types changed significantly over time. It was named after Conrad Haas, a medieval rocket pioneer who lived and worked in what is now Romania, and was the first person to describe a multistage rocket in writing.
Haas
Haas was a Romanian carrier rocket, which was developed by ARCA as part of the ELE programme. It was designed to be air-launched from a high-altitude balloon, similar to the AmericanRockoon experiments of the 1950s. Prior to the development of Haas, ARCA had already launched two Stabilo rockets from balloons. It is fueled by hydrogen peroxide and bitumen. The Haas rocket was to be a three-stage rocket intended to be capable of placing 400 kilograms of payload into low Earth orbit. Its maiden flight was to carry the European Lunar Explorer spacecraft, ARCA's entry into the Google Lunar X-Prize, following a series of engine tests which began in 2009. It was abandoned when ARCA decided to stop using solar and helium balloons for their space program.
Haas 2
Haas 2 was an orbital two-stage launcher design intended to be carried under the fuselage of the IAR 111 supersonic plane. It was planned to be powered by the new Executorliquid-fueled rocket engine under development at ARCA. Its intended launch altitude was approximately. It was intended to place a payload into low Earth orbit.
ARCAspace changed the plans of future rockets over time. As of March 2020, the company plans to develop ground-launched single-stage-to-orbit rockets which can optionally increase their payload with a booster stage. It is planned to test two stages of a small orbital rocket in independent flights in 2020, before the two are combined for a first orbital flight in 2021. This two-stage rocket is planned to have a payload capacity of 40 kg to low Earth orbit. A larger first stage is expected for 2022, followed by a single-stage-to-orbit rocket Haas 3 in 2023, carrying up to 500 kg of payload. Combining both, ARCAspace expects to achieve a payload capacity of 3 tonnes in 2024. This sequence would repeat with even larger rocket stages, leading to a 60 tonne payload rocket in 2027.
