Will the Space Elevator ever be a reality? Tim Engstrom The Cost of Space The cost of shipping payloads into space is currently thousands of dollars per kilogram[1]. Rockets are used for this job‚ subjecting the cargo to severe changeable g-forces‚ generating extreme pollution. The cost of launching a satellite by rocket is typically between $50 million and $400 million dollars[2]. Geosynchronous orbits at 35‚786 km are significantly more expensive to achieve than Low Earth orbits at less than

The UGM-84A‚ or the Harpoon missile is an anti-ship missiles capable of engaging a variety of targets. Through technological advancements‚ harpoons can now be incorporated into every naval platform in order to combat various enemies. With its built in radar‚ targets can now be detected at longer rangers and precisely eliminated. This radar system also allows for efficient guidance during flight path. Each missile has a different launch sequence‚ and varying bandwidths. This allows each to specialize

Disaster: The Mariner 1 rocket with a space probe headed for Venus diverted from its intended flight path shortly after launch. Mission Control destroyed the rocket 293 seconds after liftoff. Cause: A programmer incorrectly transcribed a handwritten formula into computer code‚ missing a single superscript bar. Without the smoothing function indicated by the bar‚ the software treated normal variations of velocity as if they were serious‚ causing faulty corrections that sent the rocket off course. 2.

Deke Slayton‚ born march 1924 in a small town in Wisconsin‚ was the single most determined astronaut ever to launch through the earth’s atmosphere. Deke was a trained fighter pilot who flew many missions in World War 2. With this background he was a sought after pilot that readily agreed to join the flight program. Deke was not the type to sit around‚ but he was the type who liked to goof off and pull jokes on other members of the team. Sometimes his jokes would get him in trouble. But there were
