Question #1:

Physics Problem, explanation!?

The Earth’s radius is about 6380 km. The
space shuttle is orbiting about 385.0 km above
Earth’s surface.
If the average speed of the space shuttle is
25500 km/h, find the time required for it to
circle Earth.
Answer in units of h.

Question #2:

When a space shuttle is launched, is the chemical reaction occurring in the engines exothermic or endothermic?

Essentially, is the heat of reaction produced in a rocket engine a positive or a negative number? This is for a chemistry project. Thanks for your help!

Question #3:

When did NASA stop allowing the public to listen in on live audio feeds of space missions?

i think it was in 1992, but i'm not sure.. and i'm not sure if they still allow it now and instead use two channels, one for public listening and the other for confidential/private listening... but i know for sure that it was because astronauts kept forgetting to hit the 'private' button on the comm when they would relay seeing objects floating around / following the shuttle.

and if anyone has some info on unidentified objects during the apollo and gemini missions, i would love to see a link :)

Question #4:

A small hole in the wing of a space shuttle requires a 12.4 cm^2 patch.?

(a) What is the patch's area in square kilometers (km^2)?

(b) If the patching material costs NASA $2.16/in^2, what is the cost of the patch?

Question #5:

space science homework help!?

i forgot my book at school and i need help

suppose two astronauts are outside the space shuttle orbiting earth. the audio speaker goes out in one of the astronauts helmets. the other astronaut shouts a message from 1 m. away can the first astronaut hear the message why or why not? explain

please help last question and i dont have my book thanks :)

Question #6:

why are all of the supposed miracles that jesus and mohammed allegedly pulled off in 1st century palestine..?

so low tech? i mean, it would have been much more miraculous if jesus rolled up into jerusalem for palm sunday in an escalade rather than on a lowly donkey...and if it was written that mohammed cruised up to heaven in a space shuttle rather than on a winged horse, the "miracle" factor would go up exponentially, and there would probably be more muslims today. Why couldn't they pull off that kind of stuff?

Question #7:

i need help with a homework question!!?

Question:A space shuttle is
scheduled to launch from Kennedy
Space Center in 3.75 hours. What time
is it now?

Launch Time is 11:20 AM

how would you write the equation and solve it?
is it possible to turn 11:20 into a fraction?if so how??

Question #8:

Physics questions. Please help!!?

The average speed of the space shuttle while in orbit is about 8905 m/s. How far does the space shuttle travel during a mission that lasts 7.4 days, which is 639360 seconds?
I used the formula distance = velocity/ time and did not get the correct answer.

A cat is being chased by a dog. Both are running in a straight line at constant speeds. The cat has a head start of 3.6 m. The dog is running with a speed of 8.9 m/s and catches the cat after 6.4 s. How fast did the cat run?
I tried this one a variety of ways and I keep coming up with the wrong answer.

Any help would be greatly appreciated.

Question #9:

Is it feasible for a manned space shuttle to travel further than the distance of mars?

In terms of oxygen, food ,power and the amount of storage space you would need to sustain astronauts.
using present technology

Question #10:

Questions about the Space Shuttle ?

1.

Three questions about the Shuttle.Say that the 6 members on ISS could not use the escape vehical and Shuttle Discovery was docked to ISS and that crew was 6 members!

Now how can all 12 Astronaunts get back to Earth safely?

2.What is the HIGHEST orbit the Shuttle ever got to?

3.IF ok " IF " the Shuttle was approaching Edwards AFB but something happened could the shuttle land at Area 51?

Question #11:

Where can I buy a Hy-fish?

You know, that RC plane that looks like a space shuttle and runs on hydrogen. I've seen it everywhere online but I can't find a place to buy it! Help!

Question #12:

why in all space movies, except "2001", is there man made gravity to hold the characters on the floor?

but then when somebody takes a shuttle to the surface of a world, they pretty much have to rely on aerodynamics and rocketry instead of zero gravity, thus the scenes where they come burning in and lose control instead of just floating down to the surface?

Question #13:

How many years would it take to reach Alpha Centauri traveling in a space shuttle at 22,000 MPH?

You heard wrong. The star gate bridge has re-opened for business a few weeks ago and is fully operational.

Question #14:

A movie about a girl came from the space to distroy Earth?

About 9 years ago I watched a movie that looks like species but I don't think that is it.
The start of the movie that there was a shuttle in the sapce tha NASA lost contact with and they send a rescue mission to rescue the crew of the shuttle so they found them all dead and then they -I think - went to a rock in the space and when they get into it the found big glass boxes each one carry a naked girl , so they took one to Earth to make some test.
And thats all I can remember.

Question #15:

what is meaning of space shuttle?

space shuttle.

Question #16:

How much of the Space Shuttle thrust goes to overcome air drag?

Hi,

How much of the Space Shuttle thrust goes to overcome air drag? If I could have an estimate percentage would be great.

Thanks.

Question #17:

Why couldn't Obama have 1-upped Bush and anounced "Mission Accomplished" after landing in a space shuttle"?

Remember the first time we accomplished the mission inIraq after Bush announced that we won the war?

Well why couldn't Obama have 1-upped Bush and anounce "Mission Accomplished" while landing after orbiting earth's atmosphere in a space shuttle?

I mean c'mon...what happened to hope and change?

Question #18:

Why are we wasting BILLIONS of dollars to give free food, shelter, and free medical care to illegal Mexicans?

Instead of using those billions to go back to the moon!?!
Something to advance American science and maybe better the lives of AMERICAN people with new medicine and technology!

Those illegal Mexicans can go back to their OWN country and starve to death for all I care!
And the majority of Americans feel this way too!
We need to take care of our OWN people, and move on the future for our OWN people!
Not let tens of MILLIONS of worthless illegal aliens drag us down their third world level!


NASA tests most powerful booster rocket ever
(AFP) – 4 hours ago
WASHINGTON — NASA and aerospace company ATK Aerospace Systems successfully tested Tuesday the most powerful solid-fuel rocket engine ever, even though its future in the space program remains in doubt.
A huge roar and massive flames accompanied the two-minute "static" or non-flight test of the five-segment DM-2 (Demonstration Motor 2) rocket booster in the western desert state of Utah.
The DM-2 was designed as the first stage of the Ares I rocket to provide the lift-off thrust for the next generation of Orion spacecraft, which NASA hoped would return astronauts to the moon by 2020.
US President Barack Obama has said he plans to cancel the Constellation program in which the boosters would have been used, throwing the fate of the next-generation engine into question.
The second test of the DM-2 was aimed at seeing if it could work at lower temperatures and verify the performance of new design materials.
The solid rocket boosters are an upgrade in design over ones used to propel NASA's shuttle fleet into space and are the largest and most powerful ever designed for flight.
Once the shuttle program ends early next year, the United States will rely on Russia's Soyuz rockets to carry its astronauts to the International Space Station until a commercial US launcher can be developed, scheduled for 2015.
The second test of the DM-2, aided by more than 760 on-board measurement devices, showed the motor's performance had met all expectations.
"For every few degrees the temperature rises, solid propellant burns slightly faster," said Alex Priskos, first stage manager for Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Alabama.
"Only through robust ground testing can we understand how material and motor performance is impacted by different operating conditions."
Seeking to cut the massive US budget deficit, Obama's administration has proposed scrapping the costly and over budget Constellation rocket program.
Instead, NASA would concentrate on research and development that could, over a longer time-frame, eventually see astronauts travel outside low Earth orbit and even aim for Mars.
The US space agency would also be encouraged to develop operations with commercial partners to fly astronauts to the space station.
