Bacillus glennii sp. nov. and Bacillus saganii sp. nov., isolated from the vehicle assembly building at Kennedy Space Center where the Viking Spacecraft were assembled.
International journal of systematic and evolutionary microbiology, 2020Co-Authors: Arman Seuylemezian, Logan C. Ott, Sarah Wolf, Jomel Fragante, Oscar Yip, Rüdiger Pukall, Peter Schumann, Parag VaishampayanAbstract:Two Gram-stain-positive, motile, endospore-forming, aerobic strains, designated V44-8T and V47-23aT, were isolated from environmental air sampling at the vehicle assembly building at Cape Canaveral, Florida, where the Viking Spacecraft were assembled. Growth was observed at pH 7-9 (optimum, pH 9) for strain V44-8T, and pH 5-10 (pH 9) for strain V47-23aT. Both strains displayed growth in 0-5 % NaCl with an optimum at 1 % for strain V44-8T; 0 % for strain V47-23aT. Strains V44-8T and V47-23aT grew optimally at 32 °C, (15-32 °C) and 25 °C (20-45 °C), respectively. The cell wall of both strains contained meso-diaminopimelic acid as the diagnostic diamino acid. Both strains contained phosphatidylglycerol, phosphatidylethanolamine and diphosphatidylglycerol. The predominant cellular fatty acids were anteiso-C15 : 0, iso-C14 : 0 and iso-C15 : 0. Strain V47.23aT shared its highest 16S rRNA sequence similarity with Bacillus cavernae DSM-105484T at 96.9%, and V44.8T with Bacillus zeae DSM-103964T at 96.6 %. Based on their phenotypic characteristics and phylogenetic position inferred from 16S rRNA gene sequence analyses, the isolates were identified as being a members of the genus Bacillus that forms a separate clade when compared to close relatives. Average nucleotide identity and average amino acid identity values between strains V44-8T and DSM-103964T were 72.1% and 67.5 %; V47-23aT and DSM-105484T were 62.4% and 69.1%, respectively. Based on the phenotypic, genomic and biochemical data, strains V44-8T and V47-23aT represent two novel species in the genus Bacillus for which the names Bacillus glennii sp. nov. [type strain, V44-8T (=ATCC BAA-2860T =DSM 105192T)], and Bacillus saganii sp. nov. [V47-23aT (=ATCC BAA-2861T=DSM 105190T)] are proposed.

Draft Genome Sequences of 12 Dry-Heat-Resistant Bacillus Strains Isolated from the Cleanrooms Where the Viking Spacecraft Were Assembled.
Genome announcements, 2018Co-Authors: Arman Seuylemezian, Kerry K. Cooper, Wayne Schubert, Parag VaishampayanAbstract:ABSTRACT Spore-forming microorganisms are of concern for forward contamination because they can survive harsh interplanetary travel. Here, we report the draft genome sequences of 12 spore-forming strains isolated from the Manned Spacecraft Operations Building (MSOB) and the Vehicle Assembly Building (VAB) in Cape Canaveral, FL, where the Viking Spacecraft were assembled.

The search for Martian life begins, 1959 - 1965
2019Co-Authors: NasaAbstract:When the Viking Spacecraft was launched to Mars in 1975, three biological experiments and a gas chromatograph-mass spectrometer, instruments with an intellectual and technological history reaching back to the early days of American space science, were on board. A systematic study of the evolution of the Martian surface and atmosphere was conceived with the following goals: (1) determination of the physical and chemical conditions of the martian surface as a potential environment for life; (2) determination whether life is or was present on Mars; (3) determination of the characteristics of that life, if present; and (4) investigation of the pattern of chemical evolution without life.

Titan/Centaur D-1T TC-3 Viking B Flight Data Report
2019Co-Authors: NasaAbstract:Titan/Centaur TC-3 was launched from the Eastern Test Range, Complex 41, at 02:34 PM EDT on Tuesday, September 9, 1975. This was the third operational flight of the newest NASA unmanned launch vehicle. The Spacecraft was the Viking B, the second of two orbiting and landing missions to Mars planned for the 1975 Martian launch opportunity. The objective of the launch phase of the mission, to inject the Viking Spacecraft onto the planned transfer orbit to Mars, was successfully accomplished. A review of the launch vehicle system flight data is presented.

Space Spurred Computer Graphics
2018Co-Authors: Nasa, Dicomed Corp.Abstract:Dicomed Corporation was asked by NASA in the early 1970s to develop processing capabilities for recording images sent from Mars by Viking Spacecraft. The company produced a film recorder which increased the intensity levels and the capability for color recording. This development led to a strong technology base resulting in sophisticated computer graphics equipment. Dicomed systems are used to record CAD (computer aided design) and CAM (computer aided manufacturing) equipment, to update maps and produce computer generated animation.
