Planetary Resources' Arkyd-6 ready for launch [spaceflightinsider.com]

After years of development, the Planetary Resources-built Arkyd-6 is finally on the last leg of its journey into space. It is scheduled to be launched as a secondary payload atop India's PSLV-C40 mission in January 2018.

At approximately 4 by 8 by 12 inches (10 by 20 by 30 centimeters), Arkyd-6 is about twice the size of its predecessor, Arkyd-3R, which was deployed from the International Space Station's Kibo module airlock in 2015.

The Arkyd-6 contains the technology that will be used in Planetary Resources' asteroid exploration program such as second-generation avionics, communications, and attitude control systems, as well as orientation systems to aid in attitude control. It also includes the A6 instrument, which will provide infrared images of the Earth in the midwave slice of the spectrum.

The broadband imager spans 3 to 5 microns of the infrared spectrum. This slice of the spectrum reveals the presence of water and is sensitive to heat. As such, the A6 can search for traces of water not only on Earth but elsewhere. The ultimate objective of future versions of this instrument is to find water on near-Earth asteroids.
