On June 19, 1976, the Viking 1 Orbiter achieved orbital insertion around Mars. On July 20, the Viking 1 Lander soft-landed on the surface of Mars in the Chryse Planitia (22 degrees north, 48 degrees west) becoming the first human-made object to land on Mars. The Viking 2 Orbiter achieved Mars orbital insertion on August 7. On September 3, the Viking 2 soft-landed in Utopia Planitia (44 degrees ...

Experiments were conducted in a Mars simulation chamber (MSC) to characterize the survival of endospores of Bacillus subtilis under high UV irradiation and simulated martian conditions. The MSC was used to create Mars surface environments in which pressure (8.5 mb), temperature (-80, -40, -10, or +23 degrees C), gas composition (Earth-normal N2/O2 mix, pure N2, pure CO2, or a Mars gas mix), and...

AIMS The aims of this study were to compare the diagnostic test characteristics of ultrasound alone, metal artefact reduction sequence MRI (MARS-MRI) alone, and ultrasound combined with MARS-MRI for identifying intra-operative pseudotumours in metal-on-metal hip resurfacing (MoMHR) patients undergoing revision surgery. METHODS This retrospective diagnostic accuracy study involved 39 patients ...

Matrix-attachment regions (MARs) are DNA elements that are defined by their abilities to bind to isolated nuclear matrices in vitro. The DNA sequences of different matrix-binding elements vary widely. The locations of some MARs at the ends of chromatin loops suggest that they may represent boundaries of individual chromatin domains. As such, MARs may play important roles in regulating transcrip...

Mars Sample Return is the highest priority science mission for the next decade as recommended by the 2011 Decadal Survey of Planetary Science [1]. This article presents the results of a feasibility study for a Mars Sample Return mission that efficiently uses emerging commercial capabilities expected to be available in the near future. The motivation of our study was the recognition that emergin...

The magnetometer and electron reflectometer investigation (MAG/ER) on the Mars Global Surveyor spacecraft has obtained magnetic field and plasma observations throughout the near-Mars environment, from beyond the influence of Mars to just above the surface (at an altitude of approximately 100 kilometers). The solar wind interaction with Mars is in many ways similar to that at Venus and at an act...
