The two-stage[1] Blue Whale 1 is a partially reusable orbital rocket in development.[6] Launching from a sea launch pad in Jeju space center in South Korea,[7] it can deliver up to 170 kg to a Sun-synchronous orbit with an altitude of 500 km. The maiden flight was planned for July 2020 but has been delayed several times. Perigee Aerospace hopes to build the capacity to launch up to 40 Blue Whale 1 rockets per year at a price of less than US$3 million. The orbital maiden flight of Blue Whale 1 is expected to take place in late 2024, preceded by a suborbital test flight scheduled for May 2024.[8]
Started in 2012, Perigee Aerospace began by developing and launching numerous sounding rockets for meteorological research for the Korean government. In 2018 and 2019 the company received two rounds of venture capital backing from some of South Korea's leading technology investors including Samsung Venture Investments and LB Investment (a subsidiary of LG) to support the development of Blue Whale.The company is also supported by KAIST, South Korea's top technical research institution.[9]
According to an interview posted on the website of Expedition College in March 2020, an educational program by Dong-A Science,[10] Perigee Aerospace was planning to launch a suborbital sounding rocket developed in collaboration with KAIST.[11] This sounding rocket, designated Blue Whale 0.1, was launched on 29 December 2021 in order to validate the engines of the Blue Whale 1 rocket. The flight was terminated shortly after takeoff due to unexpectedly strong winds.[12]
Third flight of Blue Whale 0.1 took place 24 March 2022 from Jeju Island. It was suborbital flight test and it was successful.[13]
