NASA

There have been 6 orbiters.

Enterprise was first. Never flew in space. Was built for Approach and Landing tests (ALT).

Then came Columbia, Challenger, Atlantis, Discovery. Endeavour is the baby of the fleet and was built to replace Challenger.

Columbia and Challenger were destroyed in accidents. Enterprise is in a museum.

Up until today, they used the Shuttle. Since this was the last shuttle mission, they will need to use the Soyuz space capsules until NASA comes up with a replacement vehicle, which is not even on the drawing board.

The smoke that comes out of the bottom of a rocket is its "exhaust", much like the smoke and steam you see from a car's exhaust pipe on a cold day. But most of it you can't see : a huge volume of expanding hot gases. When rocket fuel "burns" (whether it is liquid hydrogen, kerosene, or solid propellant), it combines with oxygen to release incredible amounts of heat energy. The released gases (water vapor, carbon dioxide, and other compounds) are rapidly heated and violently expand, and the only way out is through the nozzles at the base of the rocket. This thunderous rush of gases zooms out of the rocket, and according to Newton's law of action and reaction, the rocket is pushed in the other direction, which is ideally "up."

It takes a lot of energy to lift a heavy rocket against gravity, and accelerate it to the high speed (40000 km/hr, or 25000 mph) that it needs to reach orbit. Once in space, however, it will continue to move without much help as it circles the Earth.

The answer is National Aeronautics and Space Administration.

The NASA space shuttles launched from the Kennedy Space Center in Florida. Specifically, they used Launch Complex 39, which consisted of two launch pads: Pad 39A and Pad 39B.

The United States launched the Viking space probes. Viking 1 was launched on August 20, 1975, and Viking 2 was launched on September 9, 1975. These probes were part of NASA's Viking program to study Mars.

The last space shuttle launch was originally planned for early 2011, but it was delayed to July 8, 2011. The Space Shuttle Atlantis (STS-135) was the final shuttle mission of NASA's Space Shuttle program before the fleet was retired.

It's a tie. The first shuttle to fly into space was Columbia during mission STS-1.

The commander was veteran astronaut John Young and he was assisted by the rookie pilot Robert Crippen.

one rocket that exploded was the challenger shuttle

Ronald E. McNair is survived by his wife Cheryl and his two children. McNair was a physicist and astronaut for NASA whose life ended abruptly during mission STS-51L, also know as the Challenger disaster.

Apollo 3 was a test flight and therefore had no crew.

The most successful space probe launched to Neptune was Voyager 2. It made its closest approach to Neptune in 1989, providing valuable data and images of the planet and its moons. Voyager 2 remains the only spacecraft to have visited Neptune.

The space race between the United States and the Soviet Union resulted in significant achievements for space exploration. Key outcomes include the first human in space (Yuri Gagarin), the first manned moon landing (Apollo 11), the development of space stations (Salyut and Skylab), and advancements in satellite technology and space science.

Currently, NASA's Perseverance rover is exploring Mars, collecting samples for future return to Earth. The International Space Station continues to host astronauts from various countries for research and experimentation. Commercial companies like SpaceX and Blue Origin are working on sending astronauts and payloads to space as well.

The Saturn V rocket stood 363 feet (111 meters) tall at launch.

STS stands for Space Transportation System and refers to NASA's Space Shuttle program. It was active from 1981 to 2011 and involved a series of missions using reusable spacecraft to transport crew and equipment to space.

The International Space Station (ISS) can accommodate a crew of six astronauts at a time. This small crew size is due to limitations in space, resources, and life support systems aboard the spacecraft.

Space station shuttles, probes, and rockets are all types of spacecraft used for space exploration. They are designed to travel beyond Earth's atmosphere, carry equipment and instruments for research, and conduct experiments in space. Additionally, they all require advanced technology, rigorous testing, and reliable propulsion systems to operate effectively in the harsh environment of space.

NASA has given us advancements in space exploration technology, such as the Apollo missions to the moon, the Mars rover missions, and the Hubble Space Telescope. NASA has also contributed to our understanding of Earth through satellites that monitor the environment and climate. Additionally, NASA's research has led to innovations in everyday products, like memory foam and improved solar panels.

N.A.S.A stands for National Aeronautic and Space Administration.

Yes, there have been teenagers who have worked for NASA as interns or through educational programs. These opportunities provide valuable experience and help foster interest in science and technology among young people.

1)Complete the international space station

2)Develop , build and fly a new crew exploration vehicle, by 2014.

3)Develop a program to return humans to the moon, establish a lunar base and pursue subsequent exploration of mars and other destinations .

The establishment of NASA was spurred by the Soviet Union's launch of the satellite Sputnik in 1957, which sparked fears of technological and military superiority. This led to the creation of NASA in 1958, consolidating several existing U.S. government agencies involved in space research and exploration under one organization.
