The new IOS TubeSat PS Kit is the low-cost alternative to the CubeSat. It has three-quarters of the mass (0.75-kg or 1.65-lb) and volume of a CubeSat, but still offers plenty of room for most experiments or applications. And, best of all, the price of the TubeSat kit actually includes the price of a launch into Low-Earth-Orbit on an IOS NEPTUNE 30 launch vehicle. Since the TubeSats are placed into self-decaying orbits 310 kilometers (192 miles) above the Earth’s surface, they do not contribute to the long-term build-up of orbital debris.
After operating for a few months (the exact length of time on orbit is dependent on solar activity), they will safely re-enter the atmosphere and burn-up. TubeSats are designed to be orbit-friendly. Launches are expected to begin in the first quarter of 2011.
