It varies over time, but as of Oct 2021, the Expedition 65 crew comprises NASA astronauts Shane Kimbrough, Megan McArthur, Mark T. Vande Hei, and JAXA astronaut Akihiko Hoshide, ESA astronaut Thomas Pesquet, and Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov.

The name of the US space administration is NASA, which stands for National Aeronautics and Space Administration. It is responsible for the nation's civilian space program and for aeronautics and aerospace research.

The space shuttle is a pretty heavy critter. It weighs a couple of thousand tons! And it has no wings to speak of. Just some little "projections" on the sides of the vehicle to help flair it out at the end of its "fall" to earth. (It flies like a brick, if that helps.) It's rate of descent in normal operation is pretty darn high. Anyway, there are no "reverse thrusters" on the rockets to slow it down like on jet airplanes. And there are no flaps on the "wings" to increase the chord of that wing (giving it more lift) to allow it to land at a slower speed. The result is that it comes in really "hot" when it lands; it's really ripping along.

The shuttle is moving at between 600 and 700 miles per hour when it begins final approach (at perhaps 3,000 feet). It deploys some aerodynamic brakes, which are some panels that are hinged in the front and are pushed out at the rear by hydraulics. These slow the vehicle more, and it is moving at between 300 and 400 miles per hour as it nears the ground. After touchdown, the drag chute is deployed to further slow the vehicle, which is still moving at a bit over 200 miles per hour. There are brakes on the shuttle, and they are used in the final run to bring the vehicle to a stop. But the brakes would take all day to slow the craft without the drag chute. And there may not be enough runway (the dry lake bed in California, or the runway in Florida) to get this thing completely stopped without the help of the chute.

The drag chute is a simple and elegant solution to the problem of dragging the shuttle down into a moderate roll from the 200+ mile per hour speed it is moving at as it puts its wheels on the ground. Just so you know, drag chutes were used on several types of aircraft, including a couple of the century series fighters, and the X-15 rocket plane. We also saw them on the SR-71 and the B-52, among other aircraft. They work like a champ, and have been proved in long service (though these chutes weren't as large as the shuttle's drag chute.

The International Space Station was launched in 1998. It is a collaborative project involving multiple countries and serves as a research laboratory in low Earth orbit.

Canadarm2 and Dextre, also known as the Special Purpose Dexterous Manipulator, are major components of the mobile service system of the International Space Station that were designed and built by the Canadian Space Agency. Canadarm2 is a robotic arm used for capturing and docking incoming spacecraft, while Dextre is a dual-armed robot that performs maintenance tasks on the exterior of the space station.

Congress determines what NASA will do based on the budget provided each year. The agency also reports to the President of the United States by way of the Office of Science and Technology Policy in the Executive Office of the President.

NASA had a wonderful impact. They discovered a new planet, Coolhiulu, where they discovered an entire race of alien species they named Laurelfus. Without NASA we would not have obtained many of the amazing things we have today. Such as, the microwave, the internet, and the human race. i eat dogs hahahhaha lollolololol

"Sally" was astronaut Sally Ride's nickname. She was the first American woman in space and a role model for many aspiring space explorers. Ride's accomplishments and contributions to space exploration have left a lasting impact on NASA and the world.

Explorer 9 was the first in a series of 3.66 m inflatable spheres to be successfully placed into orbit solely for the determination of atmospheric densities. It was identical in its objectives and configuration to the earlier unsuccessful launch of Explorer S-56.

The spacecraft consisted of alternating layers of aluminum foil and Mylar polyester film. Uniformly distributed over the aluminum surface were 5.1 cm-diameter dots of white paint for thermal control. The sphere was packed in a tube 21.6 cm in diameter and 48.3 cm long and mounted in the nose of the fourth stage of the launch vehicle. Upon separation of the third and fourth stages, the ejection bellows, a nitrogen gas bottle, inflated the sphere and a separation spring ejected it out into its own orbit.

The two hemispheres of aluminum foil were separated with a gap of Mylar at the spacecraft's equator and served as the antenna. A 136 MHz, 15 mW beacon was carried for tracking purposes, but the beacon failed on the first orbit and the SAO Baker-Nunn camera network had to be relied upon for tracking. Power was supplied by solar cells and rechargable batteries.

Explorer 9 was the first spacecraft placed in orbit by an all-solid rocket and the first spacecraft successfully launched from Wallops Island.

The spacecraft reentered the earth's atmosphere on April 9, 1964.

Manned space missions have been carried out to perform scientific research, explore new frontiers, and conduct experiments in microgravity. These missions have also been used for technology development, international collaboration, and to further humanity's understanding of the universe. Examples include the Apollo Moon landings, the International Space Station (ISS) missions, and missions to the Hubble Space Telescope for repair and maintenance.

Some challenges of cyberspace include cyber attacks, data breaches, privacy concerns, misinformation, and digital warfare. It is essential to address these challenges through cybersecurity measures, regulations, and global cooperation to ensure a safe and secure online environment for individuals, organizations, and governments.

The weight of a Saturn V rocket just before launch is approximately 3 039 000 Kg.

The Space Shuttle that exploded on takeoff in 1986 was the Challenger. This tragic event occurred on January 28, 1986, resulting in the loss of all seven crew members on board. It was later determined that the cause of the explosion was a failure in the O-rings sealing the shuttle's solid rocket boosters.

NASA aircraft are specifically designed and built to withstand the conditions present in outer space, including extreme temperatures, pressure differentials, and exposure to radiation. Their materials and construction methods are carefully selected to protect against these factors and ensure the aircraft's integrity during missions. Additionally, thorough testing and quality control measures are implemented to verify and maintain their durability in space environments.

Space Shuttle Columbia was launched on April 12th, 1981 at 0800:03 EDT. John Young and Robert Crippen were the Cmdr and Pilot on this first ever Space Shuttle flight. They returned to Earth with a perfect landing at Edwards AFB on April 14th, 1981.

On the International Space Station, you would experience microgravity, so your weight would be significantly less compared to Earth. Astronauts on the ISS feel weightless because they are falling towards Earth as fast as the station itself.

Common elements pulled from the atmosphere used in spaceflight are oxygen, hydrogen, and nitrogen. Nitrogen isn't used for propellant, its actually used prior to ignition to purge the engines of anything that may inhibit or react during ignition.

The portrait of emperor Ashoka, an Indian king, is displayed in NASA headquarters because he is known for his commitment to peace, non-violence, and diplomacy. His teachings on tolerance and compassion resonate with NASA's values of global collaboration and understanding.

The Challenger space shuttle exploded on January 28, 1986, just 73 seconds after takeoff. The tragic event resulted in the loss of all seven crew members on board.

The standard acronym for the US Space agency is NASA, the letter stand for National Aeronautics and Space Administration.

The Nomad Desert Explorer was made by the Australian company Bruder EXP-6. Its innovative design allows for easy off-road exploration and camping in remote desert areas.

The International Space Station (or ISS for short) is like a puzzle or legos. It is put together, 1 piece at a time. In all, there are 100 major peices that the ISS is built of. The ISS is expected to be finished in 2011.
