  4. Payload Assessment

  5. Mission Objectives • 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. Aerosols’ Survey • 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. Greenhouse Gases • CO2 is the fifth most abundant gas in the atmosphere, it has increased 35% in the last 300 years.Humans are responsibleforitshighincrease in theatmosphere. • 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.

  8. Greenhouse Gases

  9. Expected Gases found in the atmosphere

  10. 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.

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

  12. 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.

  13. Experimental Overview • In Flight • Measurements NOx, NO2, H2S, NH3, and H2 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

  14. Expected Results • According to the findings of RiverRock 2009, we expect to measure the following gases: NO2, NOx, NH3, H2S, and H2. 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.

  34. Risk Matrix Risk 1 – Computer system crash during flight and data could not be collected mission objectives could not be completed. Risk 2 – Dynamic port failure at the rocket vehicle valves. Risk 3 – Sampling gas tubing (PFA). Risk 4 – Power failure on some of the component making function ability limited.
