Considering the implications of the reported single spectral line detection of phosphine (PH3) by Greaves et al., we were inspired to re-examine data obtained from the Pioneer-Venus Large Probe Neutral Mass Spectrometer (LNMS) to search for evidence of phosphorus compounds. The LNMS obtained masses of neutral gases (and their fragments) at different altitudes within Venus' clouds. Published mass spectral data correspond to gases at altitudes of 50-60 km, or within the lower and middle clouds of… Expand

Phosphine gas in the cloud decks of Venus
Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic.Expand
Composition of the Venus lower atmosphere from the Pioneer Venus Mass Spectrometer
Data from the Pioneer Venus sounder probe neutral mass spectrometer confirm that the major constituents of the lower atmosphere of Venus are CO2 and N2, with the latter having a mass abundance ofExpand
Venus' Spectral Signatures and the Potential for Life in the Clouds
It is suggested that particles in Venus' lower clouds contain sufficient mass balance to harbor microorganisms, water, and solutes, and potentially sufficient biomass to be detected by optical methods, and warrant further investigations into the prospect of biosignatures inVenus' clouds. Expand
Measurements of the Venus lower atmosphere composition: A comparison of results
From the Pioneer Venus, as well as the Venera 11 and 12 spacecrafts, data on the chemical composition of the Venus atmosphere from about 700 km to the surface were obtained. In general, reasonableExpand

Composition and Structure of the Venus Atmosphere: Results from Pioneer Venus
There is a large excess of all primordial noble gases on Venus relative to Earth, and there appears to be a considerably higher abundance of sulfur compounds below 20 kilometers than in or above the main cloud layer. Expand
Pioneer Venus Sounder Probe Neutral Gas Mass Spectrometer
A neutral gas mass spectrometer was flown to Venus as part of the Pioneer Venus Multiprobe to measure the composition of its lower atmosphere. Encounter occurred on December 9, 1978. The instrument,Expand
Reassessing the possibility of life on venus: proposal for an astrobiology mission.
With their similar size, chemical composition, and distance from the Sun, Venus and Earth may have shared a similar early history and it is possible that life could exist in restricted environmental niches, where it may have retreated after conditions on the surface became untenable. Expand

The Venusian Lower Atmosphere Haze as a Depot for Desiccated Microbial Life: A Proposed Life Cycle for Persistence of the Venusian Aerial Biosphere.
It is proposed for the first time that the only way life can survive indefinitely is with a life cycle that involves microbial life drying out as liquid droplets evaporate during settling, with the small desiccated "spores" halting at, and partially populating, the Venus atmosphere stagnant lower haze layer.
