Genesis I is an experimental space habitat designed and built by the private American firm Bigelow Aerospace and launched in 2006. It was the first module to be sent into orbit by the company, and is testing various systems, materials and techniques related to determining the viability of long-term inflatable space structures. Such structures, including this module and others built by Bigelow Aerospace, are based on the NASA Transhab design, which provides increased interior volume at a reduced launch diameter and potentially reduced mass compared to traditional rigid structures.

Spacecraft history

Genesis I was launched on July 12, 2006 at 14:53:30 UTC aboard an ISC Kosmotras Dnepr rocket, launched from Dombarovskiy missile base near Yasniy, Russia. Spacecraft control was transferred to Bigelow Aerospace at 15:08 UTC after a successful orbital insertion. Designed as a one-third scale model of the full size BA 330, when in orbit the main body of the craft measures 4.4 metres (14.4 ft) long and 2.54 metres (8.3 ft) in diameter, with an interior habitable volume of 11.5 cubic metres (406.1 cu ft). As part of the expandable design, however, the module launched with a diameter of only 1.6 metres (5.2 ft), inflating to its full size after entering orbit. The expansion process took approximately ten minutes.

Genesis I suffered a major radiation event in December 2006 as a result of a solar storm. Mission controllers were able to restart the system in time, though the situation was described as being "one fault away from the spacecraft being dead." Despite this, no lasting damage appears to have occurred and the spacecraft was operating in "excellent shape" as of March 2007.

The spacecraft completed its 10,000th orbit on May 8, 2008, some 660 days after launch. By that time, Genesis I had traveled more than 430 million kilometers (270 million miles), the equivalent of going to the Moon and back 1,154 times, and had taken more than 14,000 images, including images of all seven continents. Its electrical equipment had been continuously powered since it first became operational.

Systems

Genesis I is outfitted with eight GaAs solar panel arrays, four on each end of the craft, which produce one kilowatt total power and maintain a 26 volt battery charge. It carries thirteen cameras, seven externally to monitor the physical condition of the spacecraft, such as the outer shell and solar arrays, and six internally to photograph the various objects and experiments. Internal systems established an atmospheric pressure of 7.5 psi (51.7 kPa) and use passive thermal control to keep temperatures at an average of 26 °C (79 °F), with observed limits of approximately 4.5 °C (40.1 °F) and 32 °C (90 °F). Genesis I uses a single gas tank for its inflation system, and guidance/stabilization control is performed using a network of torque rods, sun sensors, GPS and a magnetometer.

Payload

Aside from the various systems and monitoring equipment, Genesis I is orbiting with a wide variety of cargo. Bigelow employees contributed numerous photographs, toys, cards and other items, which can be seen in still images floating around the cabin. Bigelow also placed a life-sciences experiment on board, which contains Madagascar hissing cockroaches (Gromphadorhina portentosa) and so-called Mexican jumping beans, which are seeds containing the live larva of the moth Cydia deshaisiana. In addition, the company allowed NASA to include a prototype for the GeneSat series of nanosatellites. This device, called GeneBox, tested the systems and procedures that will be used on future GeneSat missions. While GeneBox carries no living organisms, future flights will use sensors and optics to measure how weightlessness affects genes and the genetic activity of cells and microscopic life.
