What is the mechanism of satellite?
A satellite is basically a self-contained communications system with the ability to receive signals from Earth and to retransmit those signals back with the use of a transponder—an integrated receiver and transmitter of radio signals.
What is the Kessler syndrome and how could it affect you?
The Kessler Syndrome is a phenomenon in which the amount of junk in orbit around Earth reaches a point where it just creates more and more space debris, causing big problems for satellites, astronauts and mission planners.
What are the actuators used on satellites?
Magnetorquer, reaction wheels are some of the actuators commonly used in small satellites.
How does a satellite stay in the air?
A satellite maintains its orbit by balancing two factors: its velocity (the speed it takes to travel in a straight line) and the gravitational pull that Earth has on it. A satellite orbiting closer to the Earth requires more velocity to resist the stronger gravitational pull.
How do satellites transmit data?
Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
How do you fix Kessler Syndrome?
Kessler’s nightmare scenario has yielded no shortage of possible debris-flushing fixes: nets, laser blasts, harpoons, giant foam balls, puffs of air, tethers and solar sails—as well as garbage-gathering robotic arms and tentacles—have all been proposed as solutions for taking out our orbital trash.
Can Kessler Syndrome be reversed?
In fact, Mason and co say that the system could reverse the Kessler syndrome, so that the rate of debris removal once again exceeds its rate of creation.
Do satellites orbit in the exosphere?
Although the exosphere is technically part of Earth’s atmosphere, in many ways it is part of outer space. Many satellites, including the International Space Station (ISS), orbit within the exosphere or below.
