What are the most common uses of artificial satellites?
The uses of Artificial satellites are:They are used for communication purpose.Carry instrument or passengers to perform experiments in space.For Weather Forecasting System.For GPS (Global Positioning System)I hope it helped, Thankyou!
How do they control satellites that go to far places like Pluto?
Regular transmissions from the NASA Deep Space Network send commands and receive data from deep space probes. Right now they are communicating with VOYAGER 1, OSIRIS-REX, MARS RECONNAISSANCE ORBITER, HAYABUSA-2, and TRANSITING EXOPLANET SURVEY SATELLITE (TESS).(Deep Space Network Now)
What are things that an artificial intelligence could do that a brain will never be able to?
An artificial intelligence will be able to do math calculations really quickly!The main thing that will set an AI apart from the human brain will be its ability to interface efficiently with the fastest and largest scale modern computer systems, including the Internet.An AI will have immediate access to all the knowledge of Wikipedia, Quora, and the Internet. It will be able to do calculations as quickly as the fastest computer, because it can connect directly to the fastest computer, or it will be running on it. Future AI will not need a brain-machine interface because it will run in a large datacenter connected directly to the Internet with the fastest data pipe around.The main weakness of AI today is its ability to learn language and build its own conceptual and perceptual models from observation. As this capacity gets better it will define the state of the art of AI.
Why don't we send a big satellite dish up in space? Wouldn't a dish in space be better as the signals wont have to travel through the atmosphere and would be much stronger?
Here are some significant reasons.SIZEHere is a picture of one of the Deep Space Network dishes alongside a Delta IV Heavy rocket, at the same scale.The dish is 70 meters across and the launch vehicle is 70.7 meters tall. The payload of the rocket must fit within the payload fairing, about which I've drawn a red ellipse.Getting such a huge object into space would be formidable. Now, there are such things as antenna that are designed to unfurl in space. To the best of my memory, the largest civilian example is the Skyterra satellite, launched in 2010. Unfurled, its reflector is 22 meters across. But such technology is difficult and expensive. We've had as many antenna refuse to unfurl as actually unfurl. And the bigger the antenna, the more challenging that becomes.POWERBut the size of the dish isn't the only concern. Those dishes are transmitters, too. They have to send signals powerful enough that the tiny antenna dish of a faraway spacecraft can receive the signal. They use 20 kilowatt transmitters. That amount of power usage would involve massive solar arrays, if done in space.ARRAY CAPABILITYAntenna arraying is combining multiple antenna to simulate a single larger one.One of the spacecraft antenna we were unable to properly deploy was the high gain antenna for the Galileo spacecraft. That meant the signal it sent back was much weaker than planned for. To compensate, NASA used five antenna dishes acting as a single large dish in order to receive that weak signal.While forming such an array in space is not impossible. It is challenging to maintain a set of spacecraft in tight formation.MAINTENANCE AND UPGRADESIt is orders of magnitude easier to perform maintenance on a malfunctioning antenna on the surface of the Earth. It is orders of magnitude easier to perform upgrades on a malfunctioning antenna on the surface of the Earth.Those dishes are more capable, more powerful, and more sensitive today than they were when they were built. Some have even been made larger.Add together all four of those reasons and it becomes easier, cheaper, and smarter - at this time - to build a ground based network of antenna than a space based network of antenna, to be used for communicating with deep space spacecraft.
What do you think artificial intelligence can do in 10-20 years? Will it have developed a lot or very slowly by then?
In ten years from now, Artificial Intelligence will continue to be developing. Currently, A-I or Machine Learning, is evolving at such a face pace, many can not even fully explain what it is. It is predicted artificial intelligence will reach sentience within the next few years. In my own opinion, along with others, Jay Tuck (Journalist and Ted Talk member) it is already here.A-I has been and is being used extensively in the U.S. Military. For example, a drone can operate independently and has the capacity to make a “kill decision” on its own. Drones are able to do this by linking their camera's to any one of Google's 100 million servers and obtain any data they need for a particular person, geographical location of an enemy.A-I is currently replacing jobs. There are about 4 million truck drivers and 7 million people who work from call centers, their jobs are going to be replaced soon in my opinion and others (Jon Markoff,Journalist. New York Times). A-I is just beginning to affect white collar workers. Currently, there are no programs in place, no safety net for these workers.The problem, in general, with A-I, is it is a multibillion industry with very little controls to how far it go, and what it can do. There are zealots out their who believe A-I will simply make us smarter, do away with aging and even become God like.Artificial Intelligence is not a fun toy which many have tried to explain it as. It does have its place in assisting diagnoses of disease and gene cell research in the medical community. It is used in self driving vehicles and decreasing accidents. Unfortunately, it will create a big divide between the rich and the poor.
How did the the Internet get started?
Did a lot of people get together and put this all into what it is today or did just one very very smart man think of of this, one day when it was raining out and. This may sound funny but it all had to start from some place! was there a lot of people or was there just one man that did all of this,no matter who did it . it had to be HArd!!
Is time the same on the surface of Earth and on a high orbit communications satellite?
I think you are asking about time dilation.I’m very excited about this topic and I can say that time is definitely different for these objects. This is because time is relative to object’s own motion. (Oh yes almighty Einstein) Einstein’s second postulate states that for observers in any inertial frames the speed of light is the same. This means Even if you are travelling at 99.9999% speed of light and fire a photon, you would still find its speed as c, unchanged. This can only be explained by having a time concept that is not universal for all frames. Time can only be relative to an objects own motion.This idea was shown in Michelson-Morley experiment and I can explain in detail if you want. ( Or just google it it’s quite a straight forward idea)If you search on Google they will definitely be using moving trains to explain this topic and that makes no sense what so ever but the maths does work. We are forced to accept this is true.Therefore, the time experienced by the satellite is definitely different from the time experienced by us. You can already tell this is true because we need to constantly adjust clocks on GPS satellites—-they are not inaccurate, atomic clocks can measure to a degree of accuracy that is already pointless to measure any more accurately.However the difference is so small that nobody could notice it.
