Answer:
Reduce the amount of CO2 in the air. ...
Increase the planetary temperature. ...
Make the planet breathable. ...
Construct plants for generating super-greenhouse gases made of complex combinations of carbon,chlorine and flourine. To successfully make Mars Earth-like, we would need to raise temperatures, have water stably remain in liquid form and thicken the atmosphere. ... The only greenhouse gas on the Red Planet that's abundant enough to provide significant warming is carbon dioxide (CO2), they noted. Man cannot alter the environment in Mars to make it more suitable for human habitation. It is virtually and logistically impossible to do so for various reasons. For this to work, you need massive changes in the environment which is not possible with what we have today. Transforming Mars into a life-friendly world doesn't have to be a herculean planet-wide effort. Humanity could make patches of the Red Planet habitable relatively cheaply and efficiently by placing thin layers of silica aerogel on or above the Martian surface, a new study suggests. Proponents of terraforming Mars propose releasing gases from a variety of sources on the Red Planet to thicken the atmosphere and increase the temperature to the point where liquid water is stable on the surface. These gases are called “greenhouse gases” for their ability to trap heat and warm the climate. Scientists have considered placing Mylar disks, with a diameter of 155 miles and a weight of 200,000 tons, to reflect sunlight onto Mars and heat the surface. The idea is that over many years, the rise in temperature would release greenhouse gasses.

Answer: The launch on January 28, 1986, was different. The sun had been up for less than an hour and air temperatures were a few notches above freezing when the crew of STS-51L boarded the orbiter Challenger that Tuesday morning. All around the country people were getting excited—in large part because the seven-person crew’s included Payload Specialist Christa McAuliffe, a schoolteacher and mother of two chosen to fly as part of NASA’s Teacher in Space program. As a civilian, she was PR catnip: infinitely relatable and proof that space was now truly open to average Americans, not just hot-shot fighter jocks. Kids nationwide would watch the launch live and know that no dream was beyond reach.But 73 seconds after Challenger’s launch, that dream quickly became a nightmare. Challenger disappeared as white vapor bloomed from the external tank. Spectators were stunned. Teachers scrambled to get their kids out to recess. And images of the grotesque, Y-shaped explosion dominated the news cycle for days to come. For the first time in its history, NASA had lost a crew on a mission—with the nation watching.
