What is a cupola window?
What is a cupola window?
Its name derives from the Italian word cupola, which means "dome". Its seven windows are used to conduct experiments, dockings and observations of Earth. ... With the Cupola attached, ISS assembly reached 85 percent completion. The Cupola's central window has a diameter of 80 cm (31 in).
How many windows does the Cupola observation module have?
Do space shuttles have windows?
The windows on the space shuttle are actually made out of aluminum silicate glass and fused silica glass. ... There are two overhead windows that the crew out of especially when docking to the space station they're using those windows to watch the orbiter approach the space station.
How does NASA determine launch window?
Ultimately, the launch window and preferred liftoff time are set by the launch service contractor. ... The most significant deciding factors in when to launch are where the spacecraft is headed, and what its solar needs are. Earth-observing spacecraft, for example, may be sent into low Earth orbit.
Why can't a shuttle take off before 10 seconds?
At exactly 10 seconds before launch, all the navigation instruments go from a rest position to active, you can see that navigation is tracking, that it knows where it wants to take the shuttle. A few seconds after that, the main engines light.
What does NASA say before takeoff?
NASA commonly employs the terms "L-minus" and "T-minus" during the preparation for and anticipation of a rocket launch, and even "E-minus" for events that involve spacecraft that are already in space, where the "T" could stand for "Test" or "Time", and the "E" stands for "Encounter", as with a comet or some other space ...
What does T minus mean?
Are the forces on a rocket taking off balanced?
Balanced forces before lift-off When a rocket is sitting on the launch pad and not moving, there are forces acting on it, but these forces are balanced. This means that the force pulling it downwards (gravity) is equal to the force pushing it upwards (support force of the ground). These forces are balanced.
Why doesn't a bat move backwards when it hits a ball?
Why doesn't the bat move backwards, when the ball hits it? ... Because the ball exerts a reaction force on the bat.
How fast does a rocket go on take off?
A spacecraft leaving the surface of Earth, for example, needs to be going about 11 kilometers (7 miles) per second, or over 40,000 kilometers per hour (25,000 miles per hour), to enter orbit.
Will we run out of rocket fuel?
So no, it is literally impossible to run out of modern rocket fuel, as we basically reuse it (when burned, turned into water vapour, rains down, we collect it and separate it into the two gasses, which can then be burned again. We will only run out of rocket fuel, once the sun stops giving us energy.
What rocket fuel does NASA use?
Who created Rockets?
Robert Hutchings Goddard
Which rocket blew up?
Watch SpaceX Mars prototype rocket nail landing, explode on pad. SpaceX's Starship prototype, the SN10, successfully landed for the first time during a test flight. Minutes later the rocket exploded on its landing pad.
When were rockets first used?
How does NASA use rockets today?
NASA uses rockets to launch satellites and to send probes to other worlds. These rockets include the Atlas V, the Delta II, the Pegasus and Taurus. NASA also uses smaller "sounding rockets" for scientific research. These rockets go up and come back down, instead of flying into orbit.
How were rockets used throughout the ages?
The thrust created by the escaping steam made the sphere rotate. Historians believe the Chinese developed the first real rockets around the first century A.D. They were used for colorful displays during religious festivals, similar to modern fireworks.
How do rockets take off?
Earth's gravity is still pulling down on the rocket. When a rocket burns propellants and pushes out exhaust, that creates an upward force called thrust. To launch, the rocket needs enough propellants so that the thrust pushing the rocket up is greater than the force of gravity pulling the rocket down.
What percentage of fuel is used during takeoff rocket?
The Saturn V rocket on the launch pad was 85% propellant by mass. It had three stages; the first using kerosene-oxygen and the second and third stages using hydrogen-oxygen....Feature.
|Vehicle||Percent Propellant (fuel)|
Why does rocket trajectory curve?
Because gravity acts straight down, the new velocity vector is closer to being level with the horizon; gravity has "turned" the trajectory downward.
Why do rockets look so slow?
In reality the mass of the rocket is reduced as fuel is burned. Therefore its acceleration also increases with time. That causes the velocity to increase even more rapidly. It looks so slow when it takes off because it is moving slowly.
Can a rocket carry humans?
Human spaceflight capability was first developed during the Cold War between the United States and the Soviet Union (USSR). ... On 5 May 1961, the US launched its first astronaut, Alan Shepard, on a suborbital flight aboard Freedom 7 on a Mercury-Redstone rocket.
Why do rockets fly east?
So if we launch the rocket toward the east, it will get another big boost from Earth's rotational motion. Now, we launch eastward. ... Then, when the spacecraft is headed in the same direction as Earth's orbital motion around the sun, the rocket gives it a final boost out of Earth orbit and on its way.
Do rockets spin?
In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. ... Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll axis and motion about this axis is called a rolling motion.
Why does spin stabilize a bullet?
To stabilize such projectiles the projectile is spun around its longitudinal (leading to trailing) axis. The spinning mass creates gyroscopic forces that keep the bullet's length axis resistant to the destabilizing overturning torque of the CP being in front of the CM.
Why does a rocket roll after launch?
The maneuver is used to place the spacecraft on a proper heading toward its intended orbit. It often consists of a partial rotation around the vehicle's vertical axis ("roll") followed by tilting the vehicle ("pitch") to follow the proper gravity turn and/or to improve aerodynamics.
Do satellites spin?
A: Satellites and other spacecraft can orbit with the rotation of the Earth, in the opposite direction of Earth's rotation, or in any other direction! Usually satellites orbit in the direction of Earth's rotation, but there are some satellites that travel in the opposite direction.
