4. Payload Assessment

5. Compare our results with RiverRock 2009 and 2010 findings. Measure selected gases in near-space conditions. Survey inorganic and organic aerosols in near-space conditions.

6. We intend to collect samples of particulate matter, with both organic and inorganic composition. In the organic fraction of the collected aerosols, we expect to find evidence that sustains the presence of amino acids and microorganisms in the atmosphere. The collection of samples will be assessed at different altitudes of the atmosphere.

7. CO2 is the fifth most abundant gas in the atmosphere, it has increased 35% in the last 300 years. Humans are responsible for its high increase in the atmosphere. Methane is a very strong greenhouse gas and its concentration has increased more than a 150%. It is released from landfills, gas, oil drillings and coal mines. Nitrous Oxide has increased at a rate of 0.2 to 0.3% per year.

11. Measurement of gases We expect to measure several greenhouse gases that contribute to the global warming. As shown in the Miller/Urey experiment some of these gases may also be the building blocks of polypeptides.

12. Stanley Miller and Harold Urey Experiment This experiment simulated the conditions present during the Earth’s formation.

13. Stanley Miller and Harold Urey Experiment The experiment showed that conditions on the primitive atmosphere favored chemical reactions that synthesized organic compounds from inorganic precursors. In 2008, a revision of the Miller/Urey experiment showed that 22 different amino acids were synthesized instead of the 5 that were originally published.

14. In Flight Measurements NO x, NO 2, H 2 S, NH 3, and H 2 Gases Semiconductor gas sensor Collection of aerosols Polymer nano-scale filter (100 to 1000 nm), TEM Ultra Thin Holey Carbon Grids Betweens Filters and Adhesive Collector

15. According to the findings of RiverRock 2009, we expect to measure the following gases: NO 2, NO x, NH 3, H 2 S, and H 2. RiverRock 2010 findings are still in process. We also expect to find both organic and inorganic aerosols. Microorganisms may also be found as a part of the organic fraction of the collected aerosols. Polypeptides or amino acids could also be obtained as shown by the Miller/Urey experiment.
