Chris Mckay
In the 1980's, Planetary scientist Chris McKay suggested that we could seed the Martian polar caps with green plants or genetically engineered microbes that extract the liquid water they need from ice. These organisms would be dark and, thus, would absorb more sunlight that would warm up the ice and increase the overall rate of evaporation.

When and How to Travel to Mars
Once every two years (780 days) the planets come close enough that the trip can expend a relatively low amount of energy and only take six to seven months to get there. Current plans use chemical propulsion to push the spacecraft out of Earth orbit and on a trajectory that will intercept Mars. Once there we just plan to "follow the water".

However, on September 23, 1999, communication with the spacecraft was lost as the spacecraft went into orbital insertion.
Characteristics of the Moon
The time between successive new moons is 29.5 days. The Moon's gravitational attraction is stronger on the side of the Earth nearest to the Moon. Tidally locked. Lunar regolith contains oxygen, silicon, magnesium, iron, calcium, aluminum and titanium. We collect Helium-3, finerglass, glass and other building materials.

Kepler's Laws of Planetary Motion
1. Each planet revolves around the Sun in an elliptical path, with the Sun occupying one of the foci of the ellipse. 2. A line joining a planet and the Sun sweeps out equal areas during equal intervals of time. 3. The squares of the planets' orbital periods are proportional to the cubes of the semi-major axes of their orbits. This has to do with the amount of time it takes a satellite to make one orbit around the Earth. This is called the orbital period. The orbital period always relates to the altitude of the satellite. Higher orbits take a longer time to complete than lower orbits. The reason for this is that, in a higher orbit, the satellite must travel a longer distance to complete one revolution, or orbital period around the Earth.

Objective of Mercury Program
1. Place manned spacecraft in Earth orbit. 2. Investigate human's performance capabilities and our ability to function in the environment of space. 3. Recover crew and spacecraft safely.
Objective of Gemini Program
1. Subject two humans and supporting equipment to long-duration flights. 2. Effect rendezvous and docking with other orbiting vehicles, and to maneuver the docked vehicles in space using the propulsion system of the target vehicle for such maneuvers. 3. Perfect methods of reentry and landing the spacecraft at a preselected land landing. 4. Gain additional information concerning the effects of weightlessness on crew members and record the physiological reactions of crew members during long-duration flights.
