The Red Planet has always been visible from Earth. It’s a tiny red speck in the sky that you can cover with your thumb, yet it remains millions of miles away. Mankind has had their eyes on Mars for quite a while — and we’re inching ever closer to landing the first crews there.

When will we have reusable materials for space travel?
One of the most exiting activities of spaceflight have occurred when astronauts and cosmonauts left their spacecraft and floated free in space. The early spacewalks or Extra Vehicehicular Activities (EVA) were done to learn if man could function free in space. Later he built and repaired structures.
NASA’s twin rovers, Spirit and Opportunity, were slated for a three month life. Both far exceeded that. Spirit is now dead but Opportunity continues its trek of exploration over Mars since 2004. The images it continues to return are staggering.
In science fiction’s golden era, giant spaceships were maneuvered with massive gyroscopes. Attached to the ship, when a force was applied, the precession of the gyroscope was transferred to the ship, causing it to rotate in pitch, yaw and roll. That concept has become a reality with reaction wheels.
