24Space Shuttle Approved by President Nixon on January 5, 1972. World’s first reusable spacecraft, as well aslargest, most complex, and most expensive.Nine years to develop, with first launch ofColumbia taking place on April 12, 1981.Designed as “space truck” to carry all U.S.scientific, military, and commercial payloads,a highly radical policy that changed afterChallenger disaster.Confined to low earth orbit – mileswith longer-distance rockets in payload bay.Seven-person crew.133 missions have been flown to date with twocatastrophic failures.Scheduled to be terminated with last flightin June 2011.

33International Space Station ISS project began in 1994 with 1st module launchedby Russia in 1998.Operated jointly by NASA, Russian Federal SpaceAgency, European Space Agency, JapaneseAerospace Exploration Agency, and CanadianSpace Agency.Continuously occupied since October 31, 2000.Used only for peaceful purposes.Visited by astronauts and cosmonauts from15 nations.Most expensive project in human history.Serviced by manned Soyuz and Shuttle spacecraftand unmapped Russian, European, and Japanesevehicles.Contains 14 separate pressurized modules.Solar-powered with photovoltaic arrays.Visible to the naked eye.Purposes are scientific research, enhancinghuman performance and health in space, earthweather observation, education, and furtheringinternational cooperation.
34Columbia Disaster February 1, 2003 Columbia disintegrated over Texas and Louisianaduring reentry at the end of a 17-day flight.All seven crew members died.Cause was determined to be a briefcase-sizedpiece of foam that fell from the External Tankonto the Orbiter at 66,000 feet after liftoff anddamaged the leading edge of the left wing.Engineers suspected damage during the flight butNASA’s managers took no action and crew wasnot told.Tiles had been damaged in previous flights butnot fatally. “Foam shedding” had become anacceptable occurrence.Investigating board was highly critical of NASA’sdecision-making and risk assessment processes.After the Columbia disaster the shuttle was idlefor two years while safety improvements weremade.

37What Lies Beyond? Voyager 1 & 2 to leave solar system and transmit data until 2020New Horizons expected to reachPluto in 2015 Then leave solar systemWikipedia: “Each Voyager space probe carries a gold-plated audio-visual discin the event that either spacecraft is ever found by intelligent life-forms from otherplanetary systems. The discs carry photos of the Earth and its life forms, a range ofscientific information, spoken greetings from the people (e.g. the Secretary-Generalof the United Nations and the President of the United States, and the children of thePlanet Earth) and a medley, ‘Sounds of Earth,’ that includes the sounds of whales,a baby crying, waves breaking on a shore, and a variety of music.”

42Proposed Next Step: The Constellation Fleet…but… Aries crew launch vehiclewith resusable solid rocketand LOX upper stageOrion crew exploration vehicleto shuttle four-person crew betweenlow earth orbit, space station, and moonAltair lunar lander that docks with Orion in low orbit then flies toward moonLunar Outpost – a base at theMoon’s south pole where the Mars Orionmission would be configured
43Constellation on the Way Out? On February 1, 2010, the Obama administrationcanceled the Constellation program.At an April 2010 Space Conference in Florida,President Obama proposed continuing developmentof the Orion capsule, but initially using it as anescape capsule for the ISS.Development of new deep space vehicles wouldbe postponed.Private companies such as SpaceX are lobbying tobuild NASA’s next manned launch vehicle.Congress has mandated that NASA build a newrocket from existing components.Thousands of jobs are scheduled to beeliminated when the shuttle is retired in 2011.
44Explosive Chemical Rockets? – There Must Be a Better Way ! Magnetoplasma Rocket: An electro-magnetic thruster thatuses radio waves to ionize and heat a propellant and magneticfields to accelerate the resulting plasma and generate thrust.Developed by Costa Rican scientist and former astronautFrankliln Chang-Diaz for testing on the International Space Station.But it will be useable only after it has already been carried into space.Space elevator: Involves traveling along a fixed structureinstead of using rocket powered launch systems.The concept refers to a cable that reaches from the surfaceof the earth on or near the equator to a platform in geostationaryorbit and a counterweight outside the geostationary orbit.Discussion of a space elevator dates to 1895 when KonstantinTsiolokovsky proposed a free-standing "Tsiolkovsky" towerreaching from the surface of earth. Its use is limited by theheight of the platform.Magnetic Levitation: A superconductor cooled to an extremelylow temperature is repelled by a magnetic field and made to levitate,the Meisner Effect. This is the principle behind the mag-lev train,whereby an extremely heavy train filled with cargo and passengerscan travel at speeds over 100 mph on a track it never even touches.The mag-lev train actually floats a centimeter above the track inseeming defiance of the law of gravity. Animals such as frogs havebeen levitated in the laboratory. But can it get us off earth?
45How About Nuclear Fusion Rockets? A fusion rocket would be driven by nuclear fusion power. Recent developmentsindicate this technology may be able to provide terrestrial based powerwithin 30 years. For space flight, the main advantage of fusion would bethe very high specific impulse, the main disadvantage being the probable largemass of the reactor. In addition, a fusion rocket may produce less radiationthan a fission rocket, reducing the mass needed for shielding.
46Even More Exotic Antigravity Even though many scientists resist the idea that antigravitycould exist, it has become the most promising field of theoreticalresearch for out-of-the-box propulsion applications.Faster than Light?American researcher Peter Grandics has stated that, “Time isfound to be a derivative of gravitation that appears at rightangles to magnetism” and proposes methods for timewarping that could be used for faster-than-light spacecraftDesign.WormholesA wormhole is a theoretical shortcut through spacetime,potentially able to be crossed by space travelers. TheSchwarzschild wormhole consists of a black hole, a whitehole, and two universes connected at their horizons by awormhole. In the film Contact, Dr. Eleanor Arroway travels tothe star system Vega through a series of wormholes.

48Are We Alone? The Search for UFOs and ETs SETI, or Search for Extraterrestrial Intelligence, is a generic term for a varietyof scientific attempts to contact intelligent life elsewhere in the universe throughelectromagnetic transmissions, including NASA-funded studies.UFO-like objects have been reported throughout history, including ancient Romeand medieval times.In 1968, Science & Mechanics magazine published detailed accounts of UFOphenomena from the Air Force’s Project Blue Book files; Air Force terminated theproject in 1970; U.S. government denies any knowledge of UFOs.Former astronauts Gordon Cooper and Edgar Mitchell say ETs are real. Mitchellsays that he was briefed on UFO/ET contacts while at NASA.Officials from the U.N., the British Royal Society, the Vatican, and many otherinstitutions back the search for extraterrestrial life.Military officers, pilots, and government officials from many countries havereliably and extensively documented UFO sightings; they do exist. What they areand who flies them are unknown.
