Mission Overview
Objectives
• Measurement of selected gases in near-space conditions.
• Inorganic and Microorganism aerosols survey in near-space conditions.
Measurement of gases
• Why gases?
– Measuring gases is an important part of the mission
since they can be the building blocks of polypeptides.
There is also an interest in measuring the gases that
cause the greenhouse effect.
Greenhouse Effect
Finding microorganisms• What type of microorganism? a) Extremophiles: b) Psychrophiles (Below freezing temperatures) c) Piezophiles (High-pressure environments ) d) Radioresistant (Resistant to Ionizing
radiation, UV) e) Endospore (Dormant stage)
Why these specimens?
Expected results• Microorganisms or endospores which can resist
extremely high levels of radiation. This includes: UV (ultraviolet), X-rays and Gamma rays. Also capable of surviving in low pressures and temperatures.
• Polypeptides or amino acids could also be obtained because the Miller and Urey components could be readily available.
Related research• Most of the studies related to atmospheric
gases which have been collected at altitudes
of 3 km have identified and measured the
following: N2, O2, Ar, O, COx, CH4, H2S, SO2,
O3, NOx, CFC, and H2O
Supporting Analysis Research•Identification of gases during the flight
– Semiconductor gas sensor
• Collection of aerosols– Polymer nano-scale filter (25 to1000 nm)
• Bio-Sample Culture Collection and Survey– Sterilized adhesive collector and Microbiology standard procedures
• Inorganic particles analysis– Auger, XPS, SIM’s and Time of Flight Mass Spectroscopy
• Size distribution and element characterization– Electron Microscopy (TEM, SEM, EDS, ELL’S)
• Laser spectroscopy analysis
