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 inSouth Korea,[7]it can deliver up to 170 kg to aSun-synchronous orbitwith 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]

Sounding Rockets

edit

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 includingSamsungVenture Investments and LB Investment (a subsidiary of LG) to support the development of Blue Whale.The company is also supported byKAIST,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 byDong-A Science,[10]Perigee Aerospace was planning to launch a suborbitalsounding rocketdeveloped in collaboration withKAIST.[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 fromJeju Island.It was suborbitalflight testand it was successful.[13]
