context_page_description: S-Series is a fleet of sounding rockets funded by the Japan Aerospace Exploration Agency that have been in service since the late 1960s. Manufactured by IHI Aerospace and operated by the Institute of Space and Astronautical Science. The nomenclature of the S-Series rockets is the number of "S"s indicates the number of stages, and the following number details the diameter of the craft in millimeters. For example, the S-310 is a single stage rocket with a diameter of 310 mm.
  On January 14, 2017, the SS-520-4 rocket attempted to become the lightest and smallest launch vehicle to send a payload to orbit, however, the rocket failed to reach orbit. A second attempt was made on February 3, 2018. This time, the rocket reached orbit and successfully deployed TRICOM-1R, a 3U CubeSat. Its 2018 launch made it the smallest orbital rocket both in mass and height.
context_section_description: The S-310 is an active single-stage sounding rocket. Like its predecessor the S-210 it was developed for observations in Antarctica. The rocket is 310 mm in diameter, and can reach an altitude of 150 km. The first flight of S-310 in January 1975 was successful, and it has been launched at Kagoshima Space Center at Uchinoura, Showa Station in Antarctica and Andøya in Norway. As of January 1, 2017 the S-310 has completed 52 sub-orbital launches, with its most recent launch occurring on August 4, 2014.
  Gross mass: 700 kg (1,540 lb)
  Height: 6.80 m (22.30 ft)
  Diameter: 0.31 m (1.01 ft)
  Apogee: 190 km (110 mi)
