Space Shuttle Endeavour
Space Shuttle Endeavour Shuttle Orbiter Endeavour (NASA Designation: OV-105) is the most recent Space Shuttle orbiter to be built. Construction began in 1987 to replace the Challenger, lost in an accident in 1986. Endeavour was first launched in 1992. The orbiter is named for the HM Bark Endeavour, the ship commanded by 18th century explorer James Cook (which explains the British spelling).

Kalpana Chawla
(July 1, 1961 - February 1, 2003) was an astronaut and space shuttle mission specialist of STS-107 (Columbia) who was killed when the craft disintegrated after reentry into the Earth's atmosphere.

Her interest in flight was inspired by J. R. D. Tata, India's first pilot. Education Chawla studied aeronautical engineering at the Punjab Engineering College in Punjab, India in 1982 where she earned her Bachelor of Science degree. Thereafter she moved to the United States to obtain a Master of Science degree in aerospace engineering from University of Texas (1984). Dr. Chawla earned a doctorate in aerospace

Worse, any increase in the weight of the upper portion of a lauch vehicle, which had just occurred, requires an even bigger increase in the capability of the lower stage used to launch it. Suddenly the two-stage system grew in size to something larger than the Saturn V, and the complexity and costs to develop it skyrocketed.

ALT
Tim Finn and Liam O'Maonlai. ALT is also an abbreviation for Assistant Language Teacher, the job title of people on the JET Programme. ALT was also an acronym by the NASA for the Approach and Landing Tests of the Space Shuttle in 1976. ALT can mean alternative lengthening of telomeres, a mechanism (other than telomerase) that cells use to maintain telomere length.

The result was that the simple DC-3 was clearly out of the picture because it had neither the cargo capacity nor the cross-range the Air Force demanded. In fact all existing designs were far too small, as a 40,000 lbs delivery to polar orbit equates to a 65,000 lbs delivery to a "normal" 28 degree equatorial orbit. In fact any design using simple straight or fold-out wings was not going to meet the cross range requirements, so any future design would require a more complex, heavier delta wing.

While all of this was going on, others were suggesting a completely different approach to the future. They stated that NASA was better off using the existing Saturn to launch their space station, supplied and manned using modified Gemini capsules on top of the Air Force's newer Titan II-M. The cost of development for this looked to be considerably less than the shuttle alone, and would have a large space station in orbit earlier.
