Wilson Hall Science shuttle notes
| Question | Answer |
|---|---|
| What president announced that a reusable spacecraft needed to be built and when? | Richard Nixon, 1972 |
| When was the last flight to the moon? | 1972 |
| What was the companies names hired to biuld the reusable spacecraft? | Boeing |
| What does NASA call the shuttle? | the obiter |
| What does ET stand for? | external fuel tank |
| What does SRB stand for? | solid rocket booster |
| What are the tanks called in the ET consrtuction? | forward tank, aft tank |
| aft | rear |
| What mixes and burns to give a tremendous amount of power? | liquid hydrogen and oxygen |
| What is made of aluminum and sprayed with a foam insulation? | ET |
| Why is the ET sprayed with a foam insulation? | to keep the liquid fuel cool enough to remain a liquid |
| What burns up in the atmoshere so the it can not be used again? | the aluminum hull of ET |
| How many pounds of fuel does the ET hold? | 1.6 million |
| How many gallons of fuel does the ET hold? | 526,000 |
| What contains a parachute and a flotation device? Why? | SRB, so it can be retrieved and reused |
| What was the 1st original shuttle called who built it? | Enterprise, Boeing |
| What shuttle was a tester and never went into space? | Enterprise |
| What shuttle was put into flight on the back of a Boeing 747? | Enterprise |
| Where did Enterpise land? | on a runway at Edwards AFB in CA |
| What was Enterprise used for? | testing landing and manuvering |
| What provides enough thrust for lift off? | SRB |
| What is the light weight rocket? | ET |
| What is the ET used for? | continue the flight into the upper atmoshere |
| thrust | a forward force that pushes an object |
| How many seconds does it take to clear the launch pad? | 6 |
| What burns all fuel in 2 minutes and then drops into the ocean? | SRB |
| What burns all fuel in 8 minutes? | ET |
| What uses its own fuel to position itself into the earth's orbit? | orbiter/shuttle |
| What were the puposes of the shuttle mission? | 1-reusable spacecraft 2-carry large payloads 3-biuld ISS 4-take men & equipment to and from ISS 5-provide man-power to the ISS |
| payload | cargo |
| What does ISS stand for? | International Space Station |
| What were the original shuttles to orbit earth and in what year? | Columbia-1981 (1st) Challenger-1983 Discoverey-1984 Atlantis-1985 |
| What were built to endure many launche and re-entries? | shuttles |
| When are shuutles due for retirement? | 2010 |
| When is the ISS due for completion? | 2010 |
| Why is NASA behind with the scheduled retirement? | ISS is still not completely finished |
| When was the Challenger launced? | 1986 |
| How was the Challenger destroyed after it was launced? | when exaust from SRB ecaped and shot hot gases into ET |
| What happened after the exaust from SRB ecaped and shot hot gases into ET? (Challenger) | the hot gases caused the ET to break apart sending the shuttle into supersonic tailspin, breaking the shuttle apart |
| What kind of fuel is in the SRB and why? | solid fuel(powder) & because it is easier to manage |
| What does the solid fuel give the SRB? | thrust to lift off |
| What is an O ring? | round rubber ring that stops a liquid from leaking |
| Why did the exaust from SRB ecape and shoot hot gases into ET? (Challenger) | it was launched on a cold night-the O rings became to hard to seal off exaust from SRB |
| Why was Endeavor built? | to replace the Challenger |
| Where was Endeavor delivered and when? | Cape Canaveral, FL- 1991 |
| When was Columbia lauched? (2nd time) | 2003 |
| What happened to Columbia and why? | broak apart during re-entry(shuttle disinigrated) because foam insulation damaged some of the tiles(heat sheild) that protected the shuttle during re-entry |
| Why do cameras now film the launch? (2nd time) | to make sure that no foam insulation breaks off and damages the shuttle |
| What did the camera see on one of the Altlantis flight? How were the astronauts able to inspect and fix it? | foam insulation damaged the shuttle & space walk |
| How many heat tiles are on a shuttle? | 24,000 |
| How many degrees can the shuttle withstand and where? | 3,000 F on nose and wing tips |
| How fast does the shuttle travel? | 17,500 mph (5 m per sec.) |
| What is the landing speed of a shuttle? | 220 mph |
| How many seconds after take off did the Challeger explode? | 73 |
| How many mile of runway does a shuttle need to land? | 2 |
| How many flight and years are shuttles desingned to last? | 100 flights OR 10 years |
| The shuttles orbit earth every______minutes | 90 |
