Flash Card
................ satellites use specific waves to establish communication between differem locations in the world.
If the satellite is revolving in a high earth orbit parallel to the equator, then its time for one revolution around the earth is same as that of rotation of earth. As a result, the satellite appears to be stationary with respect to the earth. Therefore, these satellites are called satellites.
If the height of the satellite orbit above the earth's surface is between 2000 km and 35780 km, the orbits are called ................ earth orbits.
In third and fourth stages of PSI.V types of gel used respectively are ............ and .............. .
The first person to step on the moon is
Satellites revolving around the earth with the time period same as that of rotation of earth are called ............ satellites.
................ satellite series launched by India helps in locating any place on earth's surface by fixing the location in terms of its precise latitude and longitude.
Mangalyaan is a spacecraft made by ISRO
................ satellites are used to study and forecast weather conditions on the earth.
The escape velocity on the moon is that on the earth.
Which of the following is not an objective of space missions?
If a manmade object revolves around the earth or any other planet in a fixed orbit it is called .......... satellite.
The first artificial satellite .............. was sent to space by Soviet Union in 1957.
Which of the following satellites is different?
............. can be reused in multiple launches.
Which of the following astronauts travelled through space shuttle 'Discovery first time?
A group of students from COEP Pune sent a small satellite .............. through ISRO in 2016.
A geostationary satellite
Satellite revolving around the earth at a height of 400 km above the earth's surface has a time period of about
In first and second stages of PSL.V types of gel used respectively are ............... and ............... .
In space non-essential objects revolving around the earth are termed as .................. in space.
Due to ............. we can gather information about worldwide events sitting at home.
Time taken by satellites placed in medium earth orbits for one complete revolution is
The astronomical object closest to us is ................ in our galaxy.
Time taken by satellites placed in low earth orbits for one complete revolution is
A satellite revolves around the earth in an elliptical orbit. Its speed
There are ........... attached on the both sides of an artificial satellite as wings.
If the height of the orbit of a satellite from the earth surface is increased, the tangential velocity of the satellite will
The structure of the launch vehicle and the fiel to be used is decided by
The path followed by a satellite while revolving around the planet is known as
The working of satellite launch vehicle is based on Newton ............. law of motion.
Pelar satellite launch vehicle (PSlV) designed by
The artificial satellites work on .............
How much time a satellite in an orbit at height 35780 km above earth's surface would take to complete one revolution around the earth, if the mass of the earth would have been nine times its original mass?
............ earth orbits are also called as polar orbits.
Polar satellite launch vehicle is a ............. stage satellite launch vehicle.
Main function of Indian Remote Sensing Satellite is
................ satellites help in locating any place on earth's surface by fixing the location in terms of its precise latitude and longitude.
The initial velocity (during launching) of the Mangalyaan, must be greater than ............ of the earth.
................ satellites are used in the study of forests, deserts, oceans, polar ice on earth's surface. These are also used in exploration and management of natural resources. They also collect information which guides us in case of natural calamities like flood and earthquake.
