Abstract:
Lessons for Constellation from HST:
Adapting Human Spaceflight Vehicles to Achieve Multiple Goals in Space

Not long after the development of major elements of the Apollo program in the mid-1960's, engineers, managers, and scientists began to explore how those elements might be adapted to achieve additional priority national goals in space. Perhaps the best-known of these activities was the Apollo Applications Program, which in 1965 designed a modified lunar module that would permit astronaut-tended solar and astronomical observat ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc

ppt of crew exploration vehicles

The Crew Exploration Vehicle (CEV) was the conceptual component of the U.S. NASA Vision for Space Exploration that later became known as the Orion spacecraft. The Orion CEV was part of NASA's Constellation Program to send human explorers back to the Moon, and then onward to Mars and other destinations in the solar system.

Official planning for the vehicle began in 2004, with the final Request For Proposal issued on March 1, 2005, to begin a design competition for the vehicle. For the later design and construct ....etc

automated vehicles for physically and visually challenged ppt

Of late road traffic becomes congested and unmanageable. Notwithstanding the fact that government takes all steps to reduce congestion, in view of increasing two wheelers, four wheelers not to speak of autos, all important roads are abound with vehicles. Further, many persons do not drive with diligent-neither they think of themselves nor of others. In the circumstances, it is of dire need that with the available infrastructure we should do something for the benefit of the society a ....etc

ABSTRACT
Re-entry capsules promises to intensify international competition in launch services, microgravity research and space technology development. These systems will also confer an important strategic advantage in the conduct of materials and in life science research.
The objective of this paper is to provide a modest degree of understanding of the complex inter-relation which exist between performance requirements mission constraints , vehicle design and trajectory selection of typical re-entry mission. A brief prese ....etc
