> Mission into Deep Space
> 
> According to a news report, the Japan Aerospace Exploration Agency
> (JAXA) Hayabusa 2 asteroid mission, now scheduled to launch in
> December, will carry the Abyss 2 (Shin'en 2) Amateur Radio
> satellite. A 17 kg, 50 cm diameter polyhedron, Shin'en 2, built by
> students at Kyushu Institute of Technology, makes extensive use of
> carbon-fiber reinforced plastic materials that can be bonded by heat
> to reduce its weight and the number of hardware fasteners. In
> addition to a Mode J linear transponder for Amateur Radio
> communication, Shin'en 2 will include CW and WSJT beacons. The
> inclusion of the transponder will offer an opportunity for
> earthbound radio amateurs to test the limits of their communication
> capabilities.

> "For confirming the operational status of the spacecraft in deep
> space, the know-how of the Moon-reflecting communication technology
> can be applied. By using an Amateur Radio service transponder,
> amateur stations can communicate with each other when the spacecraft
> is in near-Moon orbit," a project outline on the Shin'en 2 website
> explains. "Beyond this distance, signal detection by Morse code and
> telemetry data transmitted from the spacecraft will be performed."
> The project is expected to help pave the way for future lunar rover
> missions.  The outline is on the web at,
> http://kit-okuyama-lab.com/en/sinen2/sinen2-outline/ .
> 
> Hayabusa 2 will make a round trip to the C-type asteroid 1999 JU3,
> arriving at the asteroid in mid-2018. It then would survey and take
> samples of the asteroid before departing in December 2019, and
> return to Earth in December 2020.
> 
> Shin'en 2 will be placed into an elliptical orbit around the Sun and
> travel into a deep space between Venus and Mars. Its inclination
> will be almost zero, which means Shin-En2 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 is 149,597,871 km).
> 
> The IARU-coordinated frequencies for Shin'en 2 are: CW beacon,
> 437.505 MHz; WSJT telemetry, 437.385 MHz; Inverting SSB/CW
> transponder, 145.940-145.960 MHz uplink (LSB)/435.280-435.260 MHz
> downlink (USB). The project also is hoping to gather listener
> reports.
> 
> The ARTSAT2:DESPATCH satellite will be on the same launch. The
> satellite, a joint project by students at Tama Art University and
> Tokyo University, will carry a 30 kg "deep space sculpture"
> developed using a 3D printer, as well as an Amateur Radio payload, a
> CW beacon in the 435 MHz band.
> 
> At its maximum operational distance, it will be some 3 million km
> (1.86 million miles) from Earth about a week after launch.
