Introduction Space technologyis technologythat is related to entering, and

retrieving objects or life forms from space. The Space technology used to explore space are Rockets, space shuttles,

satellites, telescopes, and space stations. Without them, space explorationwould be impossible.

[ "Every day" technologies such asweather forecasting, remote

sensing, GPS systems, satellite television, and some long distancecommunications systems critically rely on space infrastructure. Ofsciences, astronomyand Earth sciences (via remote sensing) most notablybenefit from space technology. ]

Rockets and space shuttles help transport people to space Satellites, telescopes, and space stations help people explore space.

They also help us understand space better by taking pictures of stellarobjects.

Rockets Rocket is a self-propelled device

[ carries its own fuel.]

Also carries the oxygen, or otherchemical agent, needed to burnthe fuel.

At the very top is a smallcapsule. That is where theastronauts stay.

The rest are just fuel tanks.They carry a lot of fuel.

When coming back down thereis a parachute that comes out ofthe capsule. The capsule thenlands in an ocean and theastronauts make it home safely.

Space Shuttle Space shuttles are multipurpose, reusable

vehicles that transport humans into orbit

around the Earth. It was built to hold up toseven people with a payload of 30,000 kg(65,000 lbs.)

The saga of the space shuttle started onApril 12, 1981 with the spaceshuttle Columbia.[first test launch for spaceshuttles]. That launch was a success and

NASA conducted a couple more testlaunches.

On the 5th launch, which was b/w Nov 11to 16, 82, Columbia launched 2 commercialsatellites into the orbit.[ Sally Ride] & manyother successful launches.

Unfortunately in January 28, 1986, aterrible thing happened. The spaceshuttle Challenger exploded a few minutesafter the launch. All 7 of the crew membersonboard died.

After the Challenger explosion, all launcheswere halted until September 29, 1988.

Satellites Satellites are objects that orbitanother object in space.

They are highly specializedtools that do different tasksevery day.

Different types of satellites [2do different things] Weather satellites take

pictures of how the weather is. Communications satellites

transmit TV or telephonesignals to Earth.

2 important parts payloadand the bus.

Telescopes The telescope makes far and faintobjects appear brighter and bigger. They are typically used to observe the

sky. Different types [ Some big, some

small] "Optical Telescopes, RadioTelescopes, Infrared Telescopes,

Ultraviolet Telescopes, X-RayTelescopes, and Gamma-RayTelescopes.

The Hubble Space Telescope was builtin 1990, and it provides us with thebest pictures of space so far. Thisbecause on the Earth's surface, the

atmosphere creates a blanket that ishard to see through. The HubbleSpace Telescope is outside of theatmosphere and it can take far clearerpictures.

Space Stations

The first space stationswereSalyut(Russian)andSkylab (U.S.).

These space stations were usedto perform experiments out inspace.

They gave us valuable

information about the stars too. People could dock up to a space

station and enter it. Astronautsor cosmonauts could live inspace for long periods of time.

For example, two cosmonauts,Vladimir Titov and MusoManarov, lived the Russianspace stationMir from April1987 to December 21, 1988.

(cont..) On April 19, 1971, the Soviet Union launched the space stationSalyut 1. Therewere several dockings with the space station. A three member crew ofSoyuz11 docked withSalyut 1 and stayed at theSalyut 1 for a period of 24 days.Afterward, on the way back to land, all three crew members died. Later on, itwas found that there was an air leak, and because the crew wore no space suits,they died very quickly. The USSR launched another space station calledSalyut

2. Unfortunately, this space station broke apart before any person could liveinside of it.Mir was launched was a successor to theSalyutstations. It couldhold a two member crew and it had six docking areas.

The U.S. launchedSkylab in May 25, 1973 as a space laboratory.Skylab wasmuch larger than theSalyutspace stations by almost three and a half timeslarger. It could also hold up to three crew members.Skylab was used also tomake observations of the Sun and other astronomical bodies, make medicalstudies of what would happen to a human in space, and do other scientific

experiments. There were in all a total of three dockings that took place.Afterwards on July 11, 1979,Skylab fell through the Earth's atmosphere andmost of the debris landed in Australia.

The Internaional Space Station, which began construction in 1998, will befinished in 2004. It is a joint operation of the U.S., Russia, Canada, Japan, anda thirteen member European Space Agency. The ISS will take up space enoughto fill up 2 football fields and it can house 7 astronauts. Overall, the ISS has 100modules used for experiments, observations, and research. All of it is put

together by astronauts in many launches. It is to be completed by 2004

Space Exploration Space exploration is our human response to curiosityabout Earth, the moon, the planets, the sun andother stars, and the galaxies.

Space exploration helps us compare Earth to the restof the universe. Such exploration could reveal howthe sun, the planets, and the stars were formed and

whether life exists beyond our own world.

Black holes are gigantic cosmic monsters, exoticobjects whose gravity is so strong that not even lightcan escape their clutches

Black holes come in a wide variety of forms, fromsmall stellar-mass bodies to the supermassive beaststhat reside at the hearts of galaxies. Here are 10 of

the most extreme black holes, from the smallest tothe largest and from cannibals to rogues.
