Manned Space ProgramsSlide2
First time in space
First man in space – Yuri Gagarin (from Russia) in 1961
First American in space – Alan Shepard
Spacecraft = Freedom 7First Chinese in space – Yang LiweiFirst American to orbit earth – John GlennSlide3
Man walked in space for the first time during Project Gemini
Purpose: to use a 2-man space vehicle to develop basic technology and procedures needed to go to the moon and back in the follow-up Apollo project
Procedures: docking, extravehicular activity, monitoring of human responses to weightlessnessSlide4
apollo
During Project Apollo, men walked on the moon for the first time
Including Neil
Armstrong and Edwin Aldrin
Activities: set up experiments, collected samples, left memorials for members of Apollo 1 who perished in a fire
Command and service modules remained in orbit, but lunar module descended to the moon’s
surfaceSlide5
Space stations
Meanwhile, Soviets (Russians) were working to establish a space station in Earth orbit
The usefulness of space station “Mir” ended as a result of its age, failing equipment, and lack of funds to properly maintain it
In comparison to other space stations, the International Space Station (ISS) is larger, more modern, and is built and used by a partnership of nationsUsed for long-term space missionsSlide6
Tragedies
Space shuttle “Challenger” was lost (because of a booster/external fuel tank malfunction) in 1986.
7 crew members
Space shuttle “Columbia” disintegrated (due to insulating foam striking the wing, damaging the heat shielding which failed upon reentry) in 2003.7 crew membersSlide7
Problems
Problems that resulted from the shuttle fleet being grounded:
Delay in construction and resupply of the ISS
Heavy satellite launches were delayed or scrappedDelay of Hubble Space Telescope servicesSlide8
The future
Private companies are working to begin tourist and commercial ventures in space.
Advantages to everyday life in the U.S. =
Flame-retardant materials
Computer technology
Energy technology,
Plastics, ceramics, metals
Communication improvements
Reasons for exploration…
Wrong: trying to find life to support evolution
Right: to glorify God by discovering more about His creation
