Payload
Assessment
• 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.
• 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.
• 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.

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