American Space Agency (NASA) will launch in early May a pharmacist nanosatellite tiny yeast cultures take on board to investigate the efficacy of antimicrobial drugs in weightlessness, NASA reported today.
.
PharmaSat The satellite to be launched May 5 along with other spacecraft as "additional burden", weighs just 4.5 kilograms and will carry a micro-laboratory and controlled environment with instruments to measure the growth rate, density, temperature, state of the cells yeast and other parameters.
.
The nanosatellite also carry a computer to transmit data to Earth.
.
The authors of the experiment is to study the influence of antimicrobial drugs in yeast under conditions of weightlessness.
.
The reaction of the cell cultures will be monitored during and after application of drugs.
.
Security microbiological is of great importance for the long-term spaceflight.
.
microorganisms, particularly molds, can grow intensively in confined spaces orbital stations pose a serious health hazard for astronauts.

Pharmasat Nanosatellite

NASA will fly the PharmaSat nanosatellite as a secondary payload aboard the U.S. Air Force four-stage Minotaur 1 rocket launch Planned for the evening of May 5, 2009.
. Introduction

. PharmaSat
Weighs Approximately 10 pounds.
.
It contains a controlled environment micro-laboratory packed with sensors and optical systems that can detect the growth, density and health of yeast cells and transmit that data to scientists for analysis on Earth.
.
PharmaSat will also monitor the levels of pressure, temperature and acceleration the yeast and the satellite experience while circling Earth at 17,000 miles per hour.
.
Scientists will study how the yeast responds to an antifungal treatment to learn more about drug action in space, the satellite's primary goal.
.
Mission Description
.
After PharmaSat separates from the Minotaur 1 rocket and successfully enters low Earth orbit at approximately 285 miles above the Earth, it will activate and begin transmitting radio signals to two ground control stations.
.
The primary ground station at SRI International, Menlo Park, Calif., will transmit mission data from the satellite to the spacecraft operators in the mission control center at NASA's Ames Research Center, Moffett Field, Calif.
.
A secondary station is located at Santa Clara University, Santa Clara, Calif.
.
When NASA spaceflight engineers make contact with PharmaSat, which could happen as soon as one hour after launch, the satellite will receive a command to initiate its experiment, which will last 96 hours.
.
Once the experiment begins, PharmaSat will relay data in near real-time up to six months, to mission managers, engineers and project scientists for further analysis.
