Space Shuttle

It will probably evolve over time, but so far ships are navigated in space by a combination of celestial navigation (orientation by sighting on various stars & the subject planets with a precision instrument), onboard inertial navigation (which tracks the movement of the ship by finely recording all relative forces of reaction with precision motion sensors), and Earth based tracking using ground stations. Each of these systems cross check each other to assure accuracy.

Sharon Christa Corrigan McAuliffe, but she is better known as Christa McAuliffe. She was a teacher from Concord, New Hampshire who was selected out of about 11,000 applicants to be the first teacher in space. She, along with 6 other brave souls, died 73 seconds after takeoff.

The first Space Shuttle, originally called Constitution, was renamed Enterprise after a write in campaign to NASA. Although never designed for orbital flight, it was the first shuttle and was used for atmospheric tests prior to the first orbital flight of Columbia.

Original designs for the shuttle began in the early 70's. Enterprise was rolled out at Rockwell Aerospace in September 1976.

Why?

The benefits of operation in space to people on the ground are enormous. Weather satellites, comsats, earth resources satellites, global positioning satellites, and, yes, spy satellites all deliver enormous value to people who never leave the ground. [I admit that I have a direct financial interest in at least three of the above.]

If you mean human space travel, it could be argued that human space travel is not sufficiently useful to be worthy of public funding, but that's not the same thing as prohibiting it. If somebody wants to spend his own money to sit on a controlled explosion, let him have at it, so long as he's not going to fall on someone else in the process.

It's becoming increasingly clear that we need to learn to burn less fossil fuels. Airplanes are currently the most polluting commonly used form of travel (in grams of carbon emissions per passenger per mile). But I suspect that space travel would be far worse.

Hydrogen is a very popular rocket fuel these days. Its "pollution" is water!

I think that they should begin a real manned spaceflight program again, which we have not had since 1972. Everything since then has been a "pogostick flight", leaving the Earth, returning to the Earth, and going to no other astronomical body in between. No one cares if yet another glorified camcorder gets sent to Mars, especially if they don't bother adding a microscope in order to determine the main, #1 answer we are going to Mars to learn... is there now or has there ever been life? They are proposing to send people there, and they don't even know if Mars may contain microorganisms that would make it far too risky to ever return the crew to Earth! I think we should colonize the Moon and use it as a staging area for flights in the future, once it has been determined that no "Reverse War of the Worlds" scenario would keep crews from being able to return.

Someone above implied that space flight using hydrogen fuel is carbon-neutral. But this isn't true. You can't get energy for free, and hydrogen fuel doesn't exist in nature. In order to get energy to make it, you have to burn something else, or split atoms, use solar panels, etc. Since fossil fuels are still the main source of energy, this causes significant carbon emissions. (The same is true of hydrogen-powered cars, although hybrid cars are said to be more efficient than gasoline-only cars.)

Also, someone mentioned manned missions to Mars. As I understand it, such a mission is far too expensive to even contemplate, never mind the fact that the crew would be killed by (gamma radiation?).

Of course, neither splitting atoms nor electrolysis by solar panels is likely to make significant carbon, not that I am one of those who still actually believes in AGW (as opposed by simple natural GW caused by natural forces, which we can see signs of here and there). Money problems can always be solved, and it would be easy enough to put a survival shelter inside the water supply tank, which would prevent solar storms, etc. from killing them. The main problem, technically, is that Mars has too much gravity for an easy LM type landing and takeoff, at least not with a manned crew which would require low-efficiency rockets. The rockets can't be high-performance without turning the crew into splat. Not enough air to land with parachutes and airbags, at least not with a manned crew. That and the fact that it may not be safe to Earth to bring them back, make Mars a poor choice for destination.

Take your pick... Suffocation (there's no air in space) Severe heamorraging as the cavities and blood vessels expand and rupture. (Space is a vacumn) Freezing. (It's very cold in space) Assuming you could survive all of that, the radiation from the sun would eventually kill you. Quite quickly if there happen's to be a star (like our sun) nearby that's going through a period instability; coronal mass ejections, solar flares etc..

"Sally Ride's Single Room Earth View" is a children's book that provides an overview of Earth seen from space through the eyes of astronaut Sally Ride. The book highlights the beauty and fragility of our planet, encouraging readers to appreciate and protect our home in the vastness of space. Through vivid illustrations and simple language, it conveys the importance of environmental stewardship and global cooperation.

No. A meteorite is an object that has already come through the Earth's atmosphere from space. On the way down, they are called meteors. A space shuttle, whether above or below the atmosphere, would need to avoid meteors at all costs. Since meteors are just rocks on the way from space to Earth, a shuttle therefore could not travel to them. Two kinds of space objects that spacecraft "could" travel to are comets and asteroids. But the space shuttle is not the proper kind of vehicle for such explorations.

Actually interplanetary space does have weather, but not in the same sense as the weather on Earth e.g. it never rains in space. The Sun emits particles known as the Solar Wind and also sheds huge amounts of matter and energy in what are known as Coronal Mass Ejections.

The first space mission to space was made by the USSR. The name of the mission was Vostok-1, on the craft Kedr (cedar in English), on April 12, 1961, piloted by Cosmonaut Yuri Gagarin.

If you are wondering about the first American mission to space, it was Mercury-3. The ship was called Freedom 7, it was launched on May 5, 1961, piloted by Alan B. Shepard Jr.

Helium is used to pressurize liquid-fuel rockets because it is inert, lightweight, and non-corrosive, ensuring it does not react with the rocket's fuel or oxidizer. It helps maintain a steady flow of fuel and oxidizer to the engines by keeping the propellant tanks pressurized. Additionally, helium's low boiling point allows it to remain in a gaseous state at low temperatures, which is crucial for spacecraft operating in the vacuum of space.

She did not die!!!

Sunita Williams (born September 19, 1965) is a United States Naval officer and a NASA astronaut. She was assigned to the International Space Station as a member of Expedition 14 and then joined Expedition 15. She holds the record of the longest spaceflight (195 days) for female space travelers.

Jupiter is a gas giant with no solid surface, so no physical objects or structures have been found on Jupiter. However, the planet has been extensively studied by spacecraft and telescopes, leading to discoveries of its atmosphere, magnetosphere, and moons.

the space probe would helr us by first gathering information of mars so we can see what type of equipment will be needed.♥

hope this helps those who need it!

The space shuttle ride in Enchanted Kingdom utilizes the principles of mechanics and physics, specifically centripetal force and acceleration. The ride's movement creates a feeling of weightlessness and acceleration, mimicking the experience of space travel. Riders experience forces acting on their body as the shuttle moves along its circular path.

Liquid oxygen is typically cheaper than liquid hydrogen because oxygen is more readily available and easier to produce. Liquid hydrogen, on the other hand, requires more energy-intensive processes for production and storage, making it more expensive.

Space shuttles sometimes launch at night to take advantage of specific lighting conditions that reduce shadows and make it easier to monitor the rocket's ascent. Night launches also offer better visibility of the vehicle's flight path for tracking and safety purposes. Additionally, launching at night can help avoid conflicts with other air traffic or scheduled launches.

A space vehicle designed to orbit the Earth slowly should be put into a low orbit. Low Earth orbit allows for slower orbital speeds compared to higher orbits, making it more suitable for vehicles designed to move slowly. Additionally, low orbit provides easier access for communication, resupply, and potential crew rescue missions.

During re-entry, the space shuttle experiences increased atmospheric drag which slows it down, causing it to decelerate from supersonic speeds. This deceleration is what causes the shuttle to break the sound barrier on its return journey.

Sensors in the space shuttle can be repurposed for a factory worker by providing real-time detection of toxic chemicals in their work environment, enabling them to take immediate action to mitigate risks. This technology can help prevent exposure to harmful substances, safeguarding the health and well-being of the worker and ensuring a safer work environment.

First, if a mechanic in a jumbo jet in flight drops a tool, it will fall to the floor of the jet where he can easily pick it up. Nobody goes out of the aircraft while in flight to work on things. Even in the old B-36 bomber, in which the mechanic could work on the engines while in flight, he worked on them INSIDE the aircraft, not outside.

Second, when the International Space Station astronaut dropped her tool bag about a year ago, the toolbag continued to orbit the Earth. But the ISS isn't in a perfectly stable orbit; the Shuttle boosts it back up every year or so. Without this boost, the ISS will fall out of orbit and crash, as did the toolbag about 9 months after she dropped it.

We look for two things; high specific energy, and low mass. A heavy rocket can't fly, so the lighter the fuel, the better - but we also need to get a LOT of energy. Other less-important factors include our ability to handle the fuel safely, and the toxicity of the exhaust.

But "fuel" isn't enough; kerosene is an acceptable rocket fuel, but will not burn by itself. We also must supply an oxidizer. In a jet airplane in the air, we can use the oxygen in the air - but there is no air in space, and even if there were we couldn't capture enough of it. So, many rockets use liquid oxygen as the oxidizer.
