Shin’en 2 – Sinen2 – Abyss 2
This will be an interesting development. A satellite going into interstellar space with an Amateur Radio transponder onboard.
Shin’en 2 is a interplanetary satellite built by students at Kagoshima University in Japan that will carry a 145 to 435 MHz linear transponder (mode J) into a deep space heliocentric orbit.
The 2.85 kg spacecraft, measuring 490 × 490 × 475 mm, features a lightweight thermoplastic CFRP structure. It is powered by solar cells on the polyhedral surface of the satellite body. Shin’en 2 will orbit the Sun in an elliptic orbit between Venus and Mars. Its inclination will be almost zero, which means Shin’en 2 will stay in the Earth’s equatorial plane. The distance from the Sun will be between 0.7 and 1.3 AU. (AU is the distance between the Earth and the SUN)
- To establish communication technologies with a long range as far as moon.
- To establish a new technology of the ultra-light-weight satellite. Proposing a WSJT 29 dBm UHF downlink and a 29 dBm 20 kHz linear transponder and a CW beacon all on UHF with a VHF uplink for the transponder

Shin’en 2 is planned to launch in the 4th quarter of 2014 on an H-2A-202 rocket with Hayabusa 2 as the main payload and PROCYON and ARTSAT2:DESPATCH as secondary payloads. Shin-en2 (JG6YIG) and ARTSAT2-DESPATCH (JQ1ZNN) Launch Postponement
The new launch day will be no earlier than December 1 (Mon.), 2014 (JST).
A Japanese news report says the asteroid mission Hayabusa 2, planned to launch in December 2014 on a H-IIA rocket, will also carry the amateur radio satellite Abyss 2 (Shin’en 2).
Shin’en 2 is a polyhedron measuring 490×490×475 mm and weighing 17 kg. It was built by students at Kyushu Institute of Technology and carries a Mode J linear transponder for amateur radio communications along with CW and WSJT beacons.
Shin’en 2 will have an elliptic orbit around the Sun and travel to a deep space orbit between Venus and Mars. Its inclination will be almost zero, which means Shin’en 2 will stay in the Earth’s equatorial plane The distance from the Sun will be between 0.7 and 1.3 AU. An Astronomical Unit (AU) is 149,597,871 km.
