inflatable design, Genesis II launched with a diameter of , expanding to its full size after entering orbit. Within two days of launch, attitude control systems had damped all rotation and oriented antennae toward Earth. On 12 December 2007, Bigelow Aerospace provided an update indicating that Genesis II was in good health. All cameras had been tested and more than 4,000 photographs had been taken. The craft was in a nearly circular orbit with an eccentricity of 0.028, and had only lost from launch to that time. Attitude control systems and all eight solar arrays were operational, and no damage to the outer surface of the craft was observed. Internal pressure was noted as holding between , with the variation caused by Genesis II moving in and out of sunlight during its orbit. On 23 April 2009, Bigelow Aerospace announced that Genesis II had surpassed the 10,000 orbit mark, having been in space for 665 days and travelling over . In February 2011, Bigelow reported that the vehicle had "performed flawlessly in terms of pressure maintenance and thermal control-environmental containment". Although the design life of the spacecraft avionics was only six months, the avionics systems worked flawlessly for over two and a half years before failure. The data received after the first six months was a re-verification of the validation test suite that was accomplished during the design life period. On 17 September 2019, an alert was generated by the U.S. Air Force stating that there was a 5.6% chance that Genesis II would collide with another derelict satellite, the Soviet satellite Kosmos 1300. , the spacecraft remains in orbit. Systems Genesis II featured a number of improvements over the first pathfinder that was launched. In addition to the standard guidance control systems used on Genesis I, it had reaction wheel assemblies and a precision measurement system, which were used to affect the spacecraft's rotation rate and angular momentum without expending fuel. It carried 22 cameras (nine more than the 13 on Genesis I) for photographing and filming cargo and ship conditions both inside and out. Some of these were on articulated platforms, and one wireless camera that is capable of additional exterior imaging. Instead of the single-tank inflation system used on the first prototype craft, Genesis II employed multiple tanks for added reliability and to allow for more finely tuned gas control. Additional layers were added to the outer
