Radio tracking was used to measure the planet’s gravitational field intensities at different locations and radar altimetry helped in mapping the Venusian surface almost completely along with valuable information on elevations and depressions. The mission sent thousands of Synthetic Aperture Radar or SAR images for research and analysis. (NASA, 1994)
2. The atmosphere of Venus is very thick with lots of gaseous substances. This is responsible for poor visibility across the atmospheric blanket of the planet. Optical cameras can operate optimally when there is enough visibility. On the contrary, electromagnetic radiations can diagnose interference patterns better and hence they can penetrate even a highly dense atmospheric environment. Therefore, radars were deployed in the Magellan mission and poor visibility was overcome with the help of advanced technology. (NASA, 1994)
3. Magellan mission revealed that there is nothing on Venus such as continental or oceanic plates that are discerned on earth. Absence of such tectonic plates means there are no tectonic activities on Venus now. Also, the SAR images of Venus show that there are almost no discernable impact craters on Venusian surface. Moreover, presence of Half Crater remains another proof that establishes tectonic activities stopped on Venus’s surface in some hoary past. The surface of the planet is only 100 million years old. This is due to excessive volcanism and subsequent resurfacings. (NASA, 1994; Bindschadler et al, 1992)
4. The deuterium to hydrogen ratio is almost constant throughout our universe since the occurrence of deuterium, which is a hydrogen isotope, is very limited and evenly distributed almost in all the solar terrestrial systems. But in Venus, deuterium to hydrogen ratio is significantly high. This suggests that there were vast amounts of water in Venus. The presence of relatively higher amounts of deuterium in Venusian environment can only be explained if we assume that ...Show more

Summary

Mariner 2 space mission was based on relatively primitive instruments. Hence, activities like measuring temperatures and magnetic field intensities were carried out. Data sets constituted of microwave radiometer readings that primarily indicated high temperature on Venusian…

Only those of the aeolian (wind streaks and sand storms), cratering (erosion and degradation) and tectonic (in the Tharsis and Elysium regions) are seen at present. Another example of an ongoing process are the giant sand storms observable even on Earth that produce a yellowish-rust color on the entire Mars (Hsui 1).

Tobacco growth
This study aimed at exploring effects of type of soil on the germination and growth of Burley tobacco. The study used complete blocked design, an experimental design, and analysis of variance to establish that type of soil does not affect the plant’s germination but affects the plant’s growth.
