Space Shuttle

Space Shuttle Discovery, mission STS-31.

Liquid Nitrogen is used in a Space Shuttle to cool down the Space Shuttle Main Engine's (SSME) Main Combustion Chamber (MCC) because the temperatures experienced during lift exceed 3,315 degrees Celcius or 6,000 degrees Fahrenheit. If Liquid Nitrogen was not used the SSME would warp in shape and melt.

A solid fuel booster is like a huge firecracker. Teh Explosive is formed into a hollow cylinder open at one end. When it ignites, the interior surface of the cylinder burns. The gases that result rush out the open end, pushing the booster and anything attached in the other direction.

It technically doesn't fly. The shuttle's burn rocket fuel. The ignition of the rocket fuel makes it expand. The shuttle's rockets are a little bit like a glass shape, with one end open. In theory the explosion of the rocket fuel creates a force trying to push out in all directions at the same time. The force of the explosion going towards the bottom (closed part) of the glass pushes against that to try to move it out of the way. The part of the force going towards the open part of the glass doesn't push against anything attached to the shuttle so it doesn't affect whether the shuttle moves or not.

Let's pick some plausible numbers and work it out: Assume that you breathe 18 times per minute, you inhale 2 liters of air with each breath, and air is 18% oxygen. (18/minute) times (2 liters) times (18%) times (60 minutes/hour) times (24 hours/day) times (365 days/year) = 9,696 liters of pure oxygen, at standard atmospheric pressure. If you're not a metric person, picture this as roughly the size of 2,500 1-gallon milk-jugs. For extended space missions, it's unlikely that the total oxygen requirements for a crew of several people will all be carried aboard at launch. It'll be essential to re-cycle the used gasses on board the spacecraft.

What do you mean by spacecraft? Because if you are referring to unmanned probes that we have sent into space the farthest distance we have traveled is approximately 6.4 billion miles away from the sun with the Voyager spacecraft which was launched in 1977. To put that in perspective we are only about 93 million miles away. So that would be about 100x more distant. In fact the Voyager has already passed PLUTO and is now in the dust field that marks the edge of our galaxy called the heliosheath where the sun has very little effect anymore. In fact in the next decade the Voygager 1 could be completely out of our solar system and venturing into interstellar space.


Cheers!

Here's the deal about black holes: nothing that goes in can ever get out. So, if a space shuttle was sucked into a black hole, it would not be able to get out. The rarely happens because the people have screens and tools that help them find where the black holes are. Not even light can go through a black hole. Something no one knows is where black holes lead to.

There have been a total of 18 accidents resulting in fatalities during space missions. These accidents occurred on both crewed and uncrewed flights conducted by various space agencies around the world. Each accident serves as a reminder of the risks and challenges associated with space exploration.

In outer space, day and night may have little meaning, but keeping regular sleep and awake cycles is how the human body was designed. Submarines on Earth have the same issues as astronauts, so they divide their duties and shifts into portions not so dissimilar from yours and mine.

At the Shuttle's maximum speed of about 30,000 km/hr, it would take more than 16 years to reach Pluto. The "New Horizons" spacecraft was launched by NASA in 2006 and reached a new record velocity for spacecraft, more than 58,000 km/hr. It was further accelerated by a gravity assist from Jupiter in 2007. Even so, it will be June, 2015 before it reaches Pluto, a total mission time of 9 1/2 years.

The shortest manned space mission was the first Mercury suborbital flight by American astronaut Alan Shepard on May 5, 1961, which lasted 15 minutes and 22 seconds. The shortest unmanned space mission was Vanguard TV3, a US satellite mission that lasted less than 5 seconds before it exploded shortly after launch on December 6, 1957.

Liquid oxygen is used in space shuttles as an oxidizer for the spacecraft's fuel, typically liquid hydrogen. When mixed and ignited, liquid oxygen and liquid hydrogen create a powerful and efficient chemical reaction that generates the necessary thrust for the shuttle to break free of Earth's gravity and enter space. It is a highly efficient and reliable propellant choice for space missions.

You can use liquid H2 as fuel. NASA has been doing it since the 1960's. However, the handling and storage of liquid hydrogen is challenging, and may not be within the capability of the average person to safely manage in a personal vehicle. Liquid hydrogen could be a fuel of choice for professionally managed public transit such as busses and trains.

The development of advanced rocket technology and the creation of artificial satellites have revolutionized space exploration the most. These advancements have enabled humans to travel further into space, gather valuable data about the universe, and establish a continuous presence in space. Additionally, the construction of the International Space Station has allowed for long-term human spaceflight missions and international collaboration in space exploration.

The capsule in the Mercury space program was designed by McDonnell Aircraft Corporation. It was known as the Mercury spacecraft, or "Freedom 7" for the first manned flight with Alan Shepard in 1961.

Yes, Hubble is expected to continue operating alongside the James Webb Space Telescope (JWST). While JWST will offer new capabilities in infrared observations, Hubble will continue to provide valuable data in visible, ultraviolet, and near-infrared wavelengths. Both telescopes will complement each other in their respective strengths.

Most of outer space is composed of vacuum, which is a near-perfect emptiness with very low density of particles. It also consists of various forms of energy, such as electromagnetic radiation. Additionally, there are celestial bodies like stars, planets, asteroids, and comets scattered throughout space.

Aircraft cannot travel to or operate in space, for several reasons. # All aircraft require atmosphere for both propulsion and lift - with no atmosphere in space, an aircraft could not propel its way forward. # Aircraft do not have self-contained environmental control systems - they take in clean air from outside and circulate that air in the interior cabin. With no atmosphere, the occupants would run out of usable oxygen. # Aircraft do not have sufficient protection against solar radiation that a spacecraft experiences. The aircraft would overheat. # Even without the above problems, an aircraft does not have enough fuel to reach the space station, which is in a low-earth orbit. In short, aircraft are not designed to travel out to space.

Eagle was the lunar module of Apollo 11 that landed on the moon for the first moon landing. All of the moon landings had a lunar module which could separate from the main craft and land on the moon. It could then take off again and dock with the main craft. The different lunar modules were given different names.

They use radio waves which are a type of electromagnetic waves. Electromagnetic waves can travel through a vacuum Ligth is a type of electromagnetic wave and that travels through space from the sun and the stars.

An Extra-Vehicular Activity (EVA) during a space mission is when an astronaut ventures outside their spacecraft or space station into the vacuum of space to perform tasks such as repairs, maintenance, or experiments. EVAs are carefully planned and monitored to ensure astronaut safety in the harsh conditions of space.

About 350 kilometres (220 mi) above the surface of the Earth.

It depends on how fast the spacecraft goes. With current technology, maybe around 6 months (with an average speed of 35,000 km/h or so). But, if you were to travel 40,000 kilometers for a spacecraft, it would only take about 16 days.

Sonic booms happen in pairs when an object producing the boom passes overhead twice: once when the object approaches the observer at supersonic speeds, and again when it moves away from the observer. Consequently, an initial boom is followed by a secondary boom.
