PharmaSat was a nanosatellite developed by NASA Ames Research Center which measured the influence of microgravity upon yeast resistance to an antifungal agent. As a follow on to the GeneSat-1 mission, the Ames Small Spacecraft Division conducted the PharmaSat mission in collaboration with industry and local universities.
PharmaSat was the first nanosatellite to implement biological science guided by its Principal Investigator. The mission was designed to aid the development of medicines or techniques to enable long-term manned space travel and habitation.
The PharmaSat mission builds upon technology demonstrated by GeneSat-1, which used a CubeSat to study microfluidics and optics in the space environment. It was designed to provide life-support, growth, monitoring, and analysis capabilities for microorganisms.
PharmaSat was launched at 23:55 UTC on 19 May 2009 aboard a Minotaur I launch vehicle from Pad 0B at the Mid-Atlantic Regional Spaceport on Wallops Island. PharmaSat was flown as a secondary payload co-manifested with the US Air Force Air Force Research Laboratory's TacSat-3 spacecraft.
PharmaSat was successfully inserted into a low Earth orbit at approximately 459 km (285 mi) above the Earth, following which it was activated and began transmitting radio signals to two ground control stations. The primary ground station at SRI International in Menlo Park, California, transmitted mission data from the satellite to its operators, while a second station was located at Santa Clara University, whose Robotic Systems Laboratory was responsible for operating the satellite.
After establishing contact the satellite was commanded to initiate its experiment, which lasted 96 hours. Once the experiment began, PharmaSat relayed data in near real-time for up to six months. PharmaSat also carried an amateur radio beacon, with a frequency of 437.465 megahertz, which broadcast spacecraft telemetry. Amateur radio operators were asked to collect data from the spacecraft and provide it to the operators via the Mission Dashboard website.
