What is the name of the NASA spacecraft that is currently orbiting Mercury?
'MESSENGER' is the Mercury Mission - See the related link listed below for more information:
What would happen if an astronaut was ill in space?
If an astronaut falls ill in space, they would typically be treated using the medical equipment available onboard the spacecraft. The astronaut would also be in regular communication with medical staff on Earth who can provide guidance for treatment. In serious cases, the astronaut may need to be evacuated back to Earth for more advanced medical care.
What is space walk?
It's called a space walk when a astronaut is "walking" outside her spacecraft in outer space. see wikipedia for more info: http://en.wikipedia.org/wiki/Space_walk
When a 75 kg astronaut in space pushes against a 200 kg anvil what will happen when the astronaut lets go of the anvil while pushing it?
Since the anvil is more than twice as massive as the astronaut, the astronaut will move much more rapidly than the anvil, as they both move in opposite directions following the astronauts push. And chances are, the massive anvil with then collide with the astronaut's spacecraft, doing horrendous damage, and the foolish astronaut will then be unable to safely return to Earth. So when you are in outer space, be careful with your anvil. I wouldn't go throwing it around at random.
What is the name of the spacecraft which is orbiting the sun and provides the data for the SOLAR Center?
SOHO (Solar and Heliospheric Observatory) not to be confused with the once "red light" district of London UK. See related link for more information
When was One More Astronaut created?
One More Astronaut was created in 1996.
What is the relative speed of the spacecraft according to astronaut when He traveled for 8 years and according to earth observer is 10 years?
The difference in time experienced by the astronaut and the Earth observer is a result of time dilation, a concept from Einstein's theory of relativity. If the astronaut experiences 8 years while the Earth observer measures 10 years, the spacecraft is traveling at a significant fraction of the speed of light. The relative speed can be calculated using the time dilation formula, which reveals that the astronaut's frame of reference moves more slowly compared to that of the Earth observer. This discrepancy highlights the effects of relativistic speeds on time perception for observers in different frames of reference.
What is the name of the NASA craft that is currently orbiting Mercury?
The NASA craft currently orbiting Mercury is called the MESSENGER spacecraft. It was launched in 2004 and entered orbit around Mercury in 2011 to study the planet's composition, geology, and magnetic field.
What is a moon a star or not?
The moon is not a star. The moon is a solid, cold object orbiting a planet, and if it were orbiting alone it is large enough to be considered a planet by itself. A star is a massive ball of gas heated by internal fusion reactions, and weighs millions of times more than the moon.
Why do you continue to send orbiting spacecraft to study the moon?
Continuing to study the moon with orbiting spacecraft allows scientists to learn more about its composition, history, and potential resources. This information can offer valuable insights into the moon's formation, as well as its role in the history of the solar system. Additionally, studying the moon can also inform future exploration missions, including manned missions and potential lunar habitats.
What are the 3 main stages in exploring a planet?
The three main stages in exploring a planet are: 1. send out a spacecraft that passes one or more bodies in space without orbiting them. 2. study a planet over a long period of time. and finally, 3. land instruments on a planet or to send instruments through its atmosphere.
