Yoga is one of the six systems of Indian philosophy. The word yoga originates from the sanskrit root yuj which means Union. On the spiritual plane, it means union of the Individual Self with the Universal Self. Yoga is the union of the body, mind, emotions and intellect. Sage Patanjali penned down this subject in his treatise known as Yoga Sutras of Patanjali.
1 Mars probably had a hot liquid core at one time, but because it's a smaller planet its heat dissipated more quickly. 2  They are good candidates for having a protective atmosphere. 3  The atmosphere holds carbon dioxide and other gases that keep the planet warm and protect its surface from radiation.
To explore and work in space, human beings must take their environment with them because there is no atmospheric pressure and no oxygen to sustain life. Inside the spacecraft, the atmosphere can be controlled so that special clothing isn't needed, but when outside, humans need the protection of a spacesuit. Earth's atmosphere is 20 percent oxygen and 80 percent nitrogen from sea level to about 75 miles up, where space begins. At 18,000 feet, the atmosphere is half as dense as it is on the ground, and at altitudes above 40/000 feet, air is so thin and the amount of oxygen so small that pressure oxygen masks no longer do the job.
