Japan Aerospace Exploration Agency (JAXA) launched the SS-520-3 Sounding Rocket aimed at "research of the plasma outflow phenomena in the cusp region" from Andøya Space Center, Svalbard Rocket Range (Norway) on Thursday Nov. 4.

After the successful launch and flight, SS-520-3 dropped onto South-southwest ocean of Svalbard Rocket Range.

Type & No. of Rocket Launch Time
(Local Time)
Elevation Angle Summit Altitude Splashdown Time
SS-520-3 11:09:25 80.7 deg. 756km(490 seconds after lift off) 950 seconds after lift off

The sky was sunny, the wind speed was 3m/s with the direction south west, and the temperature was -8 degree celsius at the time of launch.

This ends the experiments of SS-520-3 Sounding Rocket. The purpose of this launch experiment is to elucidate the plasma outflow phenomena in the cusp region. The sounding rocket SS-520-3 will carried the equipment for observing electrons, ion, and electromagnetic fields and was launched to the cusp area. The radar and the aurora imaging cameras was also used for the observation on the ground.
The result of observation obtained by the experiment will be analyzed then publicized in scientific papers.

We would like to express our sincere appreciation for the support by Norwegian Space Agency (NOSA) and everyone who was involved in the launch of SS-520-3 Sounding Rocket.
