The eccentricity of an ellipse is a number related to how "egg-shaped" it is ... the

difference between the distance through the fat part and the distance through the

skinny part. That's also related to the distance between the 'foci' (focuses) of the

ellipse.

The farther apart the foci are, the higher the eccentricity is, and the flatter the ellipse is.

Comets have very eccentric orbits.

When the two foci are at the same point, the eccentricity is zero, all of the diameters

of the ellipse have the same length, and the ellipse is a circle. All of the planets have

orbits with small eccentricities.

Yes, shuttles are commonly used to transport people, especially in airports, hotels, and other large venues where a convenient and efficient people-moving solution is needed. These shuttles are usually small buses or vans that can accommodate multiple passengers at once.

The Russian Space Station Mir which had an estimated 15 years in orbit, far longer than originally planned and then there were the earlier Salyut series of space stations which helped prepare the way for future research work of Mir and the International Space Station.

The Shuttle can also carry a 65,000 payload.

There are a few reasons why there have been no more moon landings since 1972. One major reason is the high cost associated with manned missions to the moon, making them less of a priority compared to other space exploration endeavors. Additionally, focus has been shifted towards exploring other celestial bodies, such as Mars, and advancing technology that can aid in future lunar missions.

Yes, Roberta Bondar worked with NASA as a part of the space shuttle Discovery mission STS-42 in 1992. She was the first Canadian woman in space. Bondar conducted experiments related to the effects of microgravity on the human body and various life forms.

Gamma ray bursts (GRBs) are relatively rare cosmic events. On average, about one GRB is detected each day in the observable universe. However, these events are unpredictable and can vary in frequency.

The Apollo Lunar Module used on the Apollo 11 mission, nicknamed "Eagle," had an estimated cost of around $22.9 million in 1960s dollars. This cost included design, development, and construction of the spacecraft.

Yes, it is possible to build a base on the moon. Several space agencies and private companies are working on plans to establish permanent habitats on the moon to support scientific research and exploration missions. The challenges include the harsh lunar environment, lack of atmosphere, and access to resources, but progress is being made in developing technologies to overcome these obstacles.

NASA has added SpaceX to it's new program (Commercial Orbit Transportation Services) SpaceX is the 1st commercial company to ever launch and renter Earth. Under the (COTS) program it will use Dragon (payload) and Falcon 9 (launch vehicle) to replace the shuttle so it can still resupply the ISS

As of October 2021, the present administrator of NASA is Bill Nelson. He was sworn in as the 14th administrator of NASA on May 3, 2021.

The scientists involved in Apollo 11 planned, designed, and executed the mission to land the first humans on the moon. They conducted research, tested equipment, trained astronauts, and monitored the spacecraft during its journey to the moon and back. Their work was crucial in achieving the successful moon landing in 1969.

No. There has never been a double space shuttle launch.

The closest NASA ever came to this was scheduled for May of 1986 when 2 planetary probes were to be launched from shuttles in the same week.

However, NASA has had 2 space shuttles out on the launch pads at the same time several times. First in late 1985/early 1986, and the last in 2009.

A typical timeline for a space shuttle launch includes pre-launch preparations (T-3 hours), astronaut boarding (T-45 minutes), fueling (T-3 hours), final vehicle checks (T-1 hour), and liftoff at T-0. This timeline ensures that all systems are ready and aligned before launch.

One recent finding in space exploration is the discovery of liquid water beneath the surface of Mars. This finding has significant implications for the search for extraterrestrial life on the planet. Additionally, advancements in technology have enabled scientists to capture the first-ever image of a black hole in a distant galaxy.

The US Space shuttle have only launched from Florida. Russia had a space shuttle that was launched from there.

The temperature on the International Space Station (ISS) can be as high as 121 C and as low as -157 C. To tackle this, the ISS has Multi Layer Insulation (MLI). The reflective silver layer is aluminized Mylar. The copper-colored material is kapton, this is a heavier layer that protects the sheets of fragile Mylar. Mylar is aluminized so that solar thermal radiation can't get through it. Hot air that doesn't rise, heat doesn't conduct, radiators too cold for liquid water. But thanks to the Station's efficient integrated thermal control systems, the crew don't have to worry about staying cool on the ISS.

Who knows what the value is. Incalculable. Without explorers the USA wouldn't be what it is now.

Over 500 years ago people were turning away the likes of Christopher Columbus who wanted to explore routes westward toward the East Indies, as a waste of time and money. Sound familiar?

The Apollo 13 mission is often referred to as a "successful failure" by NASA. Despite the mission not achieving its objective of landing on the moon due to an oxygen tank explosion, the safe return of the crew showcased the ingenuity and teamwork of NASA engineers and astronauts.

NASA sends robots into space to gather data, conduct experiments, and explore worlds that are too harsh or distant for humans to travel to. Robots are able to endure extreme environments, work for extended periods of time with minimal maintenance, and provide valuable information that helps advance our understanding of the Universe.

gud aftrnoon me kmal 4rm India we can definitely takes the admission in nasa if we hav gud knwledge about particular subject n having n believe that we can achieve this definitely example;u studying msc n u hav a tedency to achieve some different thing than others. its does NT mean u can achive this thing by read other books ,bcoz its easy to rad or follo other philosphies but we also hav own mind power n we can do other things to improve the knowledge of others and to see the future

NASA was established by the National Aeronautics and Space Act on July 29, 1958.

When it began operations on October 1, 1958, NASA absorbed the 46-year-old NACA which had launched Explorer 1, officially Satellite 1958 Alpha, became the U.S.'s first earth satellite in January 1958.

To become a scientist in NASA we should many degrees in science.More knowledge in aeronautics and space.Should be participated and should get awards in matters of science like in science fairs and science exhibitions.They should be well talented in physical sciences.

NASA refers to a spacewalk as an Extravehicular Activity (EVA). During an EVA, astronauts leave the confines of their spacecraft to work and conduct experiments in the vacuum of space.
