Ohsumi Satellite
By: Mackenzie Little, Ramiro Rosas, Hayden Barnes
What it's does
Purpose
The Ohsumi satellite was a small observatory carrying five experiments designed to make ionospheric observations of temperature and density, measurements of solar emission, and measurements of energetic particles. A 500-km circular orbit was intended, but an elliptical orbit was achieved.
1.Launch Date: 02-11-1970
2.Launch Vehicle: L-4S
3.Launch Site: Uchinoura Space Center, Japan
4.Mass: 24 kg
5.Nominal Power: 10.3 W
6.The satellite consisted of a small instrument package attached to the fourth stage of the L-4S launch vehicle. It was equipped with two hook-type antennas and four beryllium-copper whip-type antennas (circular polarization). For power supply, a silver oxide-zinc battery with capacity 5 Ah as power supply was carried. It had a mass of 24 kg, including the burned out fourth stage.
Key Facts
7.The communication period between the OHSUMI and the ground was only for 14 to 15 hours. But, since the inserted orbit was a hyperellipse with a 337 km perigee and a 5,151 km apogee, the OHSUMI could live a long time. After reentering Earth atmosphere, the OHSUMI vanished naturally without leaving any trace, and buried itself.
Summary
The Ohsumi was launched on 1970-02-11. I was launched on a Japanese Lambda 4-S booster, making Japan the fourth country to launch a satellite into orbit on its own rocket.The satellite was a regular 26-sided polygonal prism with a circumscribed radius of 75 cm. The Ohsumi satellite was a small observatory carrying five experiments designed to make ionospheric observations of temperature and density, measurements of solar emission, and measurements of energetic particles
The Ohsumi Satellite was launched February 11, 1970. It was launched at Kagoshima Space Center in Japan. The Ohsumi Satellite was the first Japanese satellite put into orbit. It was launched at 4:25 UTC with a Lambda 4S-5 rocket from Uchinoura Space Center by Institute of Space and Aeronautical Science, University of Tokyo, now part of the Japan Aerospace Exploration Agency.
