formed in the intestines by bacterial action on sulfur-containing proteins and appears in urine after ingestion of asparagus (contributing to the characteristic odor); also used in the manufacture of various organic sulfur-containing pesticides and fungicides.

Dr Seagre said that the likelihood of "false positives" could be reduced by searching for rarer biosignature gases more closely tied to living systems, such as dimethyl sulphide (DMS), and methanethiol. He also pointed that only a technology that would be able to image a large number of exoplanets would be able to track evidences of extraterrestrial life.

Trace amounts of methanethiol (methyl mercaptan) were also added to the fuel, giving it the distinctive rotten-egg smell that would reveal any significant leakage.
