The Red Planet
Do you know there are many planets in our solar system and on of them is referred as 'the red planet'. This fourth planet from the sun, which is reddish in colour, is Mars. Mars gets its reddish colour from the high amount of iron oxide on its surface.
Mars is also home to Olympus Mons, the highest discovered mountain in the solar system. With the peak at 88,600 feet, Olympus Mons is about three times as high as Mount Everest, which is 29,029 feet, the highest peak on Earth. Mars' Valles Marineris is the solar system's largest canyon, measuring more than seven miles deep.
Of all the planets, temperatures on Mars are most similar to those on Earth. Unlike Earth, however, the thin atmosphere gives rise to fearsome dust storms that may envelop the entire planet and cause overall temperatures to rise. Mars has an extremely thin atmosphere. 95% of it is carbon dioxide, 3% is nitrogen, 1.6% is argon, and the remainder consists of traces of oxygen and water.
Mars has two moons, Phobos and Deimos. Interestingly, Phobos orbits Mars at a distance of only about 5,500 miles from its center, the closest any moon orbits its parent planet. Because Phobos has a particularly low orbit, scientists believe it will eventually crash into Mars, or, break up into pieces, possibly forming rings around the planet like Saturn.
There has long been speculation concerning the possibility of life and or liquid water on Mars. Some evidence on the planet's surface suggests the presence of liquid water at some point in history, but scientists think this water would be too salty or acidic to support life. There is compelling evidence, however, that Mars was once much more habitable to life than it is today.
Many spacecraft have attempted to visit Mars, the most notable of which was NASA's Mariner 4, the first to visit in a fly-by in 1965. In 1976, Viking 1 and 2 became the first spacecrafts to conduct successful and sustained landings on Mars. They provided the first color photographs of the "red planet." In May of 2008, the NASA Phoenix lander touched down on the north polar region of Mars to study surface features.
______ was the first spacecraft to visit Mars.
B Mariner 4
C Viking 2
why .......65 will come first or 76

Mohandas Karamchand Gandhi, the magic man of Asia, who always stood for non-violence and was a preacher of truth was born on October 02, 1869. He was born in Porbandar, a small town of Gujarat. He belonged to a well-to-do family. He grew up and went to England to study law and became a barrister. After working in the Mumbai High Court for a few years, he went to South Africa where he continuously made efforts to improve the condition of the Indians living there.
After returning to India, Gandhiji moved to Indian politics. He could not bear the miserable plight of the Indian masses suffering and starving under the British rule and to uproot it, he pledged everything in his life.
Gandhiji was a man of sound character. He wore simple clothes and ate simple food. He was a man of few words and a lot of actions. He practiced what he preached. He was loved and respected universally.
During the freedom struggle, Gandhiji was sent to jail several times. Even then freedom of India was his only goal. He launched the 'Quit India Movement' in 1942.
Gandhiji was assassinated on January 30, 1948, plunging the entire nation into gloom. The whole world still remembers and respects this wizard of the 20th century who has left a permanent mark on time.
