The history of the studies of Mars shows how controversy always existed between two main parties: one in favour and one against the existence of liquid water on the surface of the planet. Such a controversy could be understood in past time when the absence of better data than today couldnot...
We have therefore studied the survival of viruses, bacteria, yeast, and fungi under simulated Martian conditions. The environment on Mars was simulated by low temperature, proton irradiation, ultraviolet irradiation, and simulated Martian atmosphere (CO 2 95.46%, N 2 2.7%, water vapor 0.03%) in...
Venus, Mars, and the ices on Mercury and the moon: astrobiological implications and proposed mission designs. Venus and Mars likely had liquid water bodies on their surface early in the Solar System history. The surfaces of Venus and Mars are presently not a suitab... DIRK SCHULZE-MAKUCH,JAM...

A team of NASA scientists wants to draw a more complete picture of where water exists on the Moon and whether it migrates across the lunar surface, including in the permanently shadowed regions that haven't seen sunlight in perhaps a billion years or mor
RL Mancinelli,A Banin - 《Advances in Space Research the Official Journal of the Committee on Space Research》 被引量: 11发表: 1995年 Simulation and experimental study of rheological properties of CeO2–water nanofluid Metal oxide nanoparticles offer great merits over controlling rheological, thermal...
摘要: The reaction of KMnO 4 in KI disks was found to involve the immediate formation of IO 4 , which is converted to IO 3 and other products on heating at 110°. Formation of the IO 3 occurred by reaction of IO 4 ions in the matrix....
The evolution of volcanic material on Mars: Preliminary results of sand-lavas relationships from the analogy with sandy lavas in Iceland The surface of Mars is covered by volcanic rocks from few tens of millions years to 3.5 by old. The presence of water and atmosphere can strongly affect th....
