Mission
Advanced Land Observing Satellite-4 (ALOS-4)
- Type: Earth Science
- Orbit: Sun-Synchronous Orbit
- Launch Cost: $50,000,000
The Advanced Land Observing Satellite-4 (ALOS-4) is a Japanese satellite designed to observe the Earth's surface using a phased array type L-band synthetic aperture radar (PALSAR-3).
Location
Yoshinobu Launch Complex LP-2
Tanegashima Space Center, Japan
Yoshinobu Launch Complex LP-2 has witnessed the launch of 16 rockets, including 16 orbital launch attempts. While Tanegashima Space Center, Japan, has been the site for 97 rocket launches.
The Tanegashima Space Center is the largest rocket-launch complex in Japan. It is located on the southeastern tip of Tanegashima, an island located south of Kyushu, an island and region and Japan. It was established in 1969 when the National Space Development Agency of Japan (NASDA) was formed, and is now run by JAXA. The activities that take place at TNSC include assembly, testing, launching, and tracking satellites, as well as rocket engine firing tests.
Rocket
Mitsubishi Heavy Industries H3-22
The H3 Launch Vehicle is a Japanese expendable launch system.
Each H3 booster configuration has a two-digit and a letter designation that indicates the features of that configuration. The first digit represents the number of LE-9 engines on the main stage, either "2" or "3". The second digit indicates the number of SRB-3 solid rocket boosters attached to the base of the rocket, and can be "0", "2" or "4". All layouts of solid boosters are symmetrical. The letter in the end shows the length of the payload fairing, either short "S" or long "L". For example, an H3-24L has two engines, four solid rocket boosters, and a long fairing, whereas an H3-30S has three engines, no solid rocket boosters, and a short fairing.
