Space Shuttle

T is for TIME, and the minus is the amount of time left before takeoff. If you say T minus two, and TIME is 0830, it is 0828. "Holding" is another term meaning the countdown has stalled usually due to a technical problem. T minus 2 and holding in this case would mean 0828 and countdown has paused until problem is resolved.

The question is moot because I don't think the shuttle can break orbit. However, in an effort to give you some usefull answer, it took about 3 days for the Apollo missions to reach the moon, and the Sun is about 400 times further than the moon. I would suggest that the speed they were traveling to the moon it would take years. There is no reason to suppose that any craft carrying human cargo would be limited to the speeds we used on the voyages to the moon. Typical estimates for getting to Mars (about half as far from the Earth as it the EArth is from the sun) are about 6 months. That would suggest we could get to the sun in just a year. But I think the sun is an easier target to hit because of its huge gravity that pullls you in as you get closer. So as my final answer I am going to say it would be on the order of months, between 6 and 18 months depending on what orbit you were trying to achieve.

space shuttle orbiters are launched from the Kennedy Space Center in Florida. They must not only travel the ~250 miles to reach "space", they must accelerate to over 17,000 mph to maintain orbit around the Earth.

The shuttle orbiter uses its 3 main engines along with a pair of solid rocket boosters to do this.

Two out of the five (six if you count Enterprise which never actually went into space). The two space shuttles destroyed were Columbia; on February 1, 2003, when shortly before it was scheduled to conclude its 28th mission, STS-107, the Space Shuttle Columbia disintegrated over Texas and Louisiana during re-entry into the Earth's atmosphere, resulting in the death of all seven crew members, and Challenger; Space Shuttle Challenger(mission STS-51-L) broke apart 73 seconds into its flight, leading to the deaths of its seven crew members. The spacecraft disintegrated over the Atlantic Ocean, off the coast of central Florida at 11:38 EST (16:38 UTC). Disintegration of the entire vehicle began after an O-ring seal in its right solid rocket booster (SRB) failed at liftoff.

Space junk travels as fast as all material that orbits the Earth or at about 17,500 miles per hour. This is fast enough to do damage to anything the junk encounters in orbit.

The space shuttle fleet was retired due to its high operating costs, safety concerns, and the need to shift focus towards deep space exploration missions. Additionally, the shuttles had been in service for over 30 years and were becoming outdated and expensive to maintain.

The first space shuttle to be built but never flew into space was the Space Shuttle Enterprise. It was used for approach and landing tests during the late 1970s.

As the space shuttle re-enters Earth's atmosphere, it experiences extreme temperatures due to the friction between the air and its surfaces. This friction generates intense heat that can reach over 2,000 degrees Celsius. To protect the shuttle from this heat, special heat-resistant materials like thermal tiles and blankets are used on its surface.

The orbiter itself is 37.24 m in length, the external tank is 46.9m, and the Solid Rocket Boosters are 45.6m.

SUNNYVALE, California, May 1, 1992 -- When the Space Shuttle Endeavour rockets into space on its maiden voyage, it will be protected by ceramic tiles manufactured by Lockheed Missiles & Space Company, Inc. of Sunnyvale, California. NASA's entire orbiter fleet -- Columbia, Challenger, Discovery, Atlantis, and now Endeavour -- is protected from the searing heat of reentry by Lockheed's Reusable Surface Insulation. Endeavour will be protected with over 26,000 tiles. Earlier orbiters used as many as 34,000 tiles, but as the knowledge base increased, tiles on surfaces that experienced moderate reentry temperatures, such as the upper fuselage, were eventually replaced with flexible insulating blankets.

It depends on the motor. The Space Shuttle's 4-segment motor burns for 124 seconds, for instance. The Atlas V's solid rocket motors burn for 90 seconds. A common size B4 model rocket motor burns for 1 second.

it depends on the size of the rocket, the grain material, and the oxidizer to tell you how long one will burn.

The first space rocket to reach the moon and return safely was Apollo 8, which launched on December 21, 1968. During the mission, astronauts Frank Borman, James Lovell, and William Anders orbited the moon before returning to Earth on December 27, 1968.

The outer layer of a space shuttle is typically made of reinforced carbon-carbon and thermal protection tiles. The reinforced carbon-carbon helps protect the shuttle from high temperatures during re-entry, while the thermal protection tiles insulate the shuttle from the intense heat of atmospheric friction.

Many methods and tools are used to investigate planets both from Earth and in space. Telescopes, physics, fly-by missions and Mars and Moon landing equipment are all very useful in studying things outside Earth.

The first ever manned mission was done on April 12, 1961, by Yuri Gagarin (USSR).

You do not actually float. The gravity on the moon is a fraction of what it is on Earth. As a result objects weigh less and fall more slowly. You may feel almost weightless, though you still have some weight.

During liftoff, a space shuttle travels at a speed of about 17,500 mph (28,000 km/h). This speed allows it to overcome Earth's gravity and reach orbit around the planet. The intense acceleration and velocity are necessary for a successful journey to space.

Two space shuttles have experienced catastrophic failures during launch: Challenger in 1986 and Columbia in 2003. Both tragedies resulted in the loss of all crew members aboard.

Space shuttles are reusable spacecraft that were used by NASA to transport astronauts and cargo to space. They were launched like a rocket and landed like a glider. The space shuttle program operated from 1981 to 2011.

Space shuttles are used to transport astronauts and cargo to and from space, including missions to the International Space Station. They provide a reusable and cost-effective means of reaching space compared to traditional rockets. Additionally, shuttles have been instrumental in carrying out scientific research, satellite deployment, and servicing missions in space.

The first space probe to fly past the moon was the Soviet Luna 1 probe in 1959. Luna 1, also known as Mechta, was intended to impact the moon but missed and became the first human-made object to escape Earth's gravity.

An Apollo landing involved a capsule re-entering Earth's atmosphere for a water landing, using parachutes to slow its descent. In contrast, a space shuttle landing was a controlled glide to a runway on land, using wings to navigate and land like an airplane. The space shuttle also had the ability to be reused multiple times.

No, as an unaided human, you cannot fly faster than the speed of sound. The speed of sound, approximately 767 mph or 1,235 km/h at sea level, is a limit for objects moving through the air.

Yes, nuclear fuel can be used for space ships to generate power for long-duration missions. Radioisotope thermoelectric generators (RTGs) and nuclear fission reactors are two types of nuclear power sources that have been used in space missions to provide electricity and heat for spacecraft and scientific instruments. However, the use of nuclear fuel in space missions presents challenges related to safety, regulations, and potential environmental impacts.

Space shuttles are powered using rocket engines that burn liquid fuel (such as liquid hydrogen and liquid oxygen) or solid rocket boosters. Once out of Earth's atmosphere, the space shuttle relies on these engines to propel itself through space and maneuver in a zero-gravity environment.
