Methane, Ammonia on Mars? Mariner 7 Sees Hint of Life

(8.August 1969)

Pimentel´s evidence was from an infrared spectrometer, designed to detect elements by measuring their radiation.

The Curiosity rover detects oxygen behaving strangely on Mars

„We’re struggling to explain this,“ said Melissa Trainer, study author and planetary scientist at NASA’s Goddard Space Flight Center. „The fact that the oxygen behavior isn’t perfectly repeatable every season makes us think that it’s not an issue that has to do with atmospheric dynamics. It has to be some chemical source and sink (of elements into the soil) that we can’t yet account for.“

It relates back to the methane mystery.

Is there methane on Mars?

(2011)

The first discovery of methane on Mars was announced in 1969 at a press conference by the Mariner 7 Infrared Spectrometer (IRS) team just two days after the flyby.

Cassini Tastes Organic Material at Saturn’s Geyser Moon

(26.03.2008)

The Ion and Neutral Mass Spectrometer saw a much higher density of volatile gases, water vapor, carbon dioxide and carbon monoxide, as well as organic materials, some 20 times denser than expected. This dramatic increase in density was evident as the spacecraft flew over the area of the plumes.

Low-mass nitrogen-, oxygen-bearing, and aromatic compounds in Enceladean ice grains

Previous analyses inferred three different spectral types of Enceladean ice grains (Postberg et al. 2008, 2009a): Type 1 represents grains of almost pure water ice, Type 2 shows features consistent with grains containing significant amounts of organic material, and Type 3 is indicative of salt-rich water ice grains.

Organic compounds have been found on Saturn’s moon Enceladus

Before NASA’s Cassini mission studied Saturn and its moons for 13 years, beginning in 2004, Enceladus held many secrets. Cassini revealed that there was a global ocean between the moon’s icy crust and its rocky core.

Although the Cassini mission ended in a blaze of glory when it disintegrated in Saturn’s atmosphere, surprises from the data it collected will be released for years to come.
