Space Shuttle
The Space Shuttles are reusable spacecraft with wings for controlled descent into the atmosphere. They are designed to transport astronauts between earth and an orbiting space station and to deploy and retrieve satellites. Atlantis, Discovery, and Endeavour are the three Space Shuttles in operation today.

How much did space mission STS-96 cost?
The total cost for space mission STS-96 was approximately $500 million. This mission was launched on May 27, 1999, and its primary objective was to transport supplies and equipment to the International Space Station.
What was the first space mission that had people die in it?
The Soviet Union may have lost several astronauts in flight in the 1960's and early '70's. However, the Soviet Union was also very secretive about their space program; they never made any announcements until after the flight had landed. And even then, they would sometimes lie about details.
The first American astronauts to die during a space mission were the crew of the Challenger space shuttle.
A rocket is a motor that can burn fuel without requiring?
oxygen from the surrounding air, making it suitable for space travel where there is no atmosphere.
How much does it cost to send someone into space?
The cost to send someone into space can vary greatly depending on the type of mission, spacecraft, and space agency or company involved. Currently, the cost for a seat on a commercial spaceflight can range from tens of millions to hundreds of millions of dollars.
Sonic booms occur when an object travels through the air faster than the speed of sound, creating a shockwave of compressed air. This rapid change in air pressure produces a loud noise heard on the ground as a loud bang or boom.
Can a space shuttle land on Jupiter?
Jupiter is one of the four 'gas giant' planets. Unlike rocky worlds like Earth, Jupiter is composed almost entirely of gas. Inside this swirling ball of gas lies a small core of solid rock.
Jupiter is a 'gas giant', so it's not possible to land a ship on its surface. Travelling far below the clouds of this planet is not advised. Temperatures and pressures soon begin to rise. So far, no probes have survived over 150 metres below the surface of Jupiter.
It is not possible to land on Jupiter. It is made primarily from hydrogen & helium gases, with a rocky core consisting of heavier elements.
Could you see smoke from the 911 terrorrists from outer space?
Yes. Satellite photos of New York on 9/11 clearly showed the plumes of smoke.
Was the Phoenix Space mission successful?
Yes, the Phoenix Mars Lander mission, launched in 2007, was successful in discovering evidence of water ice on Mars and providing valuable data about the planet's surface. The mission operated for about five months before losing communication due to harsh winter conditions on Mars.
That would depend on where you are. We can see other planets in our own solar system, but even travelling at huge speeds, it would takes us years to reach them. So you could see Earth from a very long way and have no hope of getting back, or surviving long enough to do so.
It is a little strange that things in higher orbits actually travel more slowly than things in lower orbits. The Space Shuttle and the International Space Station both orbit in about 90 minutes, while the Moon - 250,000 miles away - take a whole month to orbit the earth.
There is one kind of orbit that has a special name and a special purpose. A satellite that orbits at 22,300 miles high will orbit the Earth in 24 hours. You might notice that the Earth revolves around its axis in 24 hours. So a satellite at that altitude orbits the Earth at the same rate that the Earth turns, which means that the satellite is moving just as fast as the Earth does. So the satellite appears to stand still in the sky!
We call this a geo-synchronous orbit. Geo, for Earth; synchronous, for "equal time". This is an especially handy orbit for things like communications satellites, which "hover" over the same spot on the equator.
How much horsepower does a space shuttle have after 10 seconds on liftoff?
This is a difficult question to ask, because it does not have a clearly defineable answer.
Power as physical quantity is defined as the amount of expended work divided by the time it took to do that work:
P = dW/dt
Work, however, is a more complex animal than you might have thought when setting the question. Work is a quantity that measures the expenditure of energy; any energy expended is measured as work:
W = -E
Thus, we need to consider how much energy the space shuttle is gaining (or how much work its engines are doing) at a given time.
The total mechanical energy of the space shuttle would in this example consist of potential energy and kinetic energy:
E(t) = Ep(t) + Ek(t) = mgh(t) + ½mv(t)2
where m is the mass of the vehicle, assumed to be close enough to constant during the ten seconds specified in the question;
g is the gravitational acceleration of 9.81 m/s2;
h(t) is the altitude of the vehicle as function of time, and
v(t) is the velocity of the vehicle as function of time.
To define the energy of the vehicle as function of time, we need to define the altitude and velocity as functions of time. To do this in meaningful way, we'll simplify the example with a few assumptions:
-the shuttle will travel upward only (constrained to one axis of motion)
-mass is constant or close enough to constant to not significantly matter, at 2,000,000 kg gross lift-off weight for the entire system stack
-the shuttle will have constant acceleration of 3g (it is limited to this acceleration for safety reasons).
Now to resolve the kinetic equations of the vehicle:
a = 3g
a = dv/dt
dv = a dt ∫(...)
∫dv = a ∫dt
v(t) = at + v0
v = dh/dt
dh/dt = at + v0
dh = at dt + v0 dt ∫(...)
∫dh = a∫t dt + v0∫dt
h(t) = ½ a t2 + v0t + h0
Thus, the energy of the vehicle at time t is
E(t) = mgh(t) + ½mv(t)2
E(t) = mg(½ a t2+ v0t + h0) + ½m(at + v0)2
To simplify things further, we can define initial velocity and altitude as zero:
h0 = 0, v0 = 0
E(t) = ½ mga t2 + ½m a2 t2 = (½ mga + ½ ma2) t2
Now, here's our function for the total mechanical energy of the vehicle. To determine the rate of energy consumption at ten seconds, we need to derivate the function by t:
E'(t) = (mga + ma2) t
Since E'(t) = dE/dt and P = dW/dt, we have our answer here by substituting our assumed values into this simple equation:
( 2,000,000 kg * 4 * 9.81 m/s2 + 2,000,000 kg * [3 * 9.81 m/s2]2 ) * 10 s
≈18.11 x 109 W = 18.11 GW
Based on this very simplified calculation, the space shuttle launch vehicle's total power output at T+10s is approximately 18 gigawatts, which translates to:
* 24,138,397.6 hp
* Full installed power output of Three Gorges Dam
* Eleven and a quarter of the projected power output of Olkiluoto 3 fission reactor (which will be the most powerful nuclear reactor in the world upon completion)
These comparisons should make it obvious why "power", especially axial power, is not especially valid or relevant quantity of capacity when you are talking about rockets, jet engines or other similar systems which rely on the reaction principle rather than mechanical traction for providing locomotion. Furthermore, the amount of chemical energy expended by the rocket motors of the space shuttle is significantly larger than the value achieved in this example; not all of the thermal energy generated in the chemical reactions is converted into potential energy and kinetic energy.
As a further exercise, you could try to define the power of a car with static 5 m/s2 acceleration. You will find that the "power" of the car varies as a function of time, rather than being a constant, clear-cut value.
Why is it that a subsonic aircraft cannot produce a sonic boom?
A subsonic aircraft flies below the speed of sound, so it does not break the sound barrier. A sonic boom is created when an object travels at or above the speed of sound, causing a buildup and release of pressure waves that result in a loud noise. Since a subsonic aircraft does not exceed the speed of sound, it does not generate a sonic boom.
Does a sonic boom occur only at the moment when an aircraft exceeds the speed of sound?
No, a sonic boom occurs continuously as an object travels faster than the speed of sound. The boom is created as the object's shock waves merge together over a certain distance known as the boom carpet, which is behind the object as it moves.
Does a sonic boom occur every time the shuttle enters earth?
A sonic boom occurs when an object travels faster than the speed of sound. If the space shuttle enters Earth's atmosphere at a speed greater than the speed of sound, it will create a sonic boom. However, the shuttle typically slows down as it enters the atmosphere to avoid this effect.
A solid does take up space. Although it doesn't take up as much mass if it were to be a liquid or a gas.For example ice doesn't take up as much space as water or water vapor

What spacecraft observed venus?
Several spacecraft have observed Venus, including NASA's Magellan spacecraft which mapped the planet's surface with radar, and the European Space Agency's Venus Express which studied the planet's atmosphere and surface. The Soviet Union's Venera program also sent several landers and probes to Venus in the 1970s and 1980s.
How fast do you have to go to make a sonic boom?
A sonic boom occurs when an object travels faster than the speed of sound, which is about 767 mph (1,235 km/h) at sea level. The exact speed required to create a sonic boom can vary depending on atmospheric conditions.
How did Mendeleev know where to leave the spaces in his periodic table?
mandeleev didn't know spaces in the Periodic Table because he doesn't arrange it john Kepler arrange it most of mendeleev discoveries of elements are few most of other element where discover by other scientist after him in 19th century
How long does it take for a shuttle travelling at 475 km per minute to reach Jupiter?
It would take approximately 168 days for a shuttle travelling at 475 km per minute to reach Jupiter, which is about 628.7 million kilometers away from Earth on average.
Why do sonic booms come two at a time?
When an object passes through the air, it creates a series of pressure waves in front of it and behind it. These waves travel at the speed of sound, and as the speed of the object increases, the waves are forced together, or compressed, because they cannot "get out of the way" of each other, eventually merging into a single shockwave at the speed of sound. This critical speed is known as Mach 1 and is approximately 1,225 kilometers per hour (761 mph) at sea level at room temperature.
In smooth flight, the shock wave starts at the nose of the aircraft and ends at the tail. Because directions around the aircraft's direction of travel are equivalent, the shock forms a Mach cone with the aircraft at its tip. So the faster it goes, the finer, (more pointed) the cone.
There is a rise in pressure at the nose, decreasing steadily to a negative pressure at the tail, followed by a sudden return to normal pressure after the object passes. This "overpressure profile" is known as an N-wave because of its shape. The "boom" is experienced when there is a sudden change in pressure, so the N-wave causes two booms, one when the initial pressure rise from the nose hits, and another when the tail passes and the pressure suddenly returns to normal. This leads to a distinctive "double boom" from supersonic aircraft.
IN SHORTER WORDS:A separate shock wave is created at both the front and back of the airplane.What is the wingspan of the Space Shuttle?
The wingspan for the space shuttle is 24 Meters and in feet: 78 Feet. hope this helps.
there are many types of airfoils but in two different categories. They're Conventional and Laminar Airfoils. They each have many designs. Such as the conventional airfoils have six basic designs of airfoils.
The Laminar Airfoils are : -
We use things made from rocks and minerals every day. If something doesn't come from a plant or an animal, it has to be mined. According to the Mineral Information Institute, it is estimated that in a lifetime,
a person living in North America will use up the following quantity of rocks and minerals:
What is the meaning behind the letter and numbers of 51-D?
The "5" means that the flight was originally scheduled to fly in 1985. The "1" means that the shuttle would launch from Florida, versus California (which would be two). The "d" means that this was the fourth flight scheduled for that year.
Some of it is from the vapors produced by the propellants in the solid rocket boosters (SRB's), but much is from the water that is dumped on the launch pad to dampen the vibrations during the launch. The SRB's combust ammonium perchlorate, aluminum, iron oxide, and a polymer. The shuttles main engines use liquid oxygen and liquid hydrogen.
