Which satellite is nearest to the earth?

Although Venus is the planet that comes closest to Earth as it sweeps by on its orbit, Mercury stays the closest to Earth the longest, according to a commentary published Tuesday (March 12) in the magazine Physics Today.

What happened to the satellites?

Two things can happen to old satellites: For the closer satellites, engineers will use its last bit of fuel to slow it down so it will fall out of orbit and burn up in the atmosphere. Further satellites are instead sent even farther away from Earth. … That way, it will fall out of orbit and burn up in the atmosphere.

Who Hacked NASA?

Gary McKinnonGary McKinnon (born 10 February 1966) is a Scottish systems administrator and hacker who was accused in 2002 of perpetrating the “biggest military computer hack of all time,” although McKinnon himself states that he was merely looking for evidence of free energy suppression and a cover-up of UFO activity and other …

How many dead satellites are in space?

2,900 dead satellitesSince the start of the space age, more than 8,6o0 satellites have been placed into orbit. Of the approximately 4,700 of those still in orbit, only 1,800 are operational, leaving 2,900 dead satellites out there orbiting aimlessly and adding to the more than 21,000 objects currently being tracked and cataloged by NASA .

What is the lowest orbiting satellite?

High earth orbitFrom geostationary to the moon, 363,104 km out, but that’s not even earth’s most distant orbiter: A NASA satellite studying solar wind has the highest point in its orbit at 470,310 km—and it’s also the lowest-flying satellite at the other end of its elliptical orbit, coming as low as 186 km.

How do I get access to a satellite?

Top 10 free sources of satellite data [2020 update]Google Earth – Free access to high resolution imagery (satellite and aerial) … USGS Satellite imagery – Landsat, MODIS, and ASTER data. … Copernicus Open Access Hub – API access to Sentinel data. … Zoom. … NASA EarthData (GIBS) – API access to NASA satellite data.

Can you hack NASA with HTML?

If you go to NASA’s website and hit CTRL-U, you will see their HTML code. If you could “hack” that code and replace all instances of “NASA” with “HTML” then you will have hacked NASA with HTML. It’s fairly easy to do that for the way the page is displayed on your own browser.

How many satellites are in space?

2,200 satellitesThere are an estimated 2,200 satellites orbiting the Earth at present, but telecommunications companies are launching dozens of new satellites regularly in hopes of providing high-speed broadband internet access to the entire planet. Just how many satellites are we talking about?

How many satellites are destroyed each year?

As of 2014, there were about 2,000 commercial and government satellites orbiting the earth. It is estimated that there are 600,000 pieces of space junk ranging from 1 to 10 cm (0.39 to 3.94 in), and on average one satellite is destroyed by collision with space junk each year.

What country has the most satellites?

the U.S.While the U.S. is the country with most satellites in space (1,308), multinational cooperations come in third place.

How do they keep satellites from crashing into each other?

Satellites are sent into space by a rocket launched from the ground with enough energy (at least 25,039 mph!) to get outside our atmosphere. Once the rocket reaches its determined location it drops the satellite into its orbit. … It is reserved for changing orbit or avoiding collision with debris.

What happens two satellites collide?

According to Gorman, if the two spacecraft collide, the smaller one will be obliterated, producing a cloud of new debris. The larger one would likely remain largely intact, but not without some damage, producing even more debris. To be 100 percent clear, this poses absolutely no danger to us here on Earth.

Did the two satellites collide?

There has only been one accidental collision between two intact satellites in different orbits. This occurred eleven years ago, involving a then-operational satellite in the Iridium communications network and a defunct Russian communications satellite.

Is satellite hack possible?

Satellites are typically controlled from ground stations. These stations run computers with software vulnerabilities that can be exploited by hackers. If hackers were to infiltrate these computers, they could send malicious commands to the satellites.

Does the ISS get hit by debris?

As it tumbles through space, the International Space Station is often hit with orbital junk, usually tiny fragments from satellites and lost equipment. … It’s pretty unnerving that something so small could cause such a significant crack, but the ISS is orbiting Earth at 17,150 miles per hour.
