If you aren’t so lucky to have cable/satellite and you may have to wiggle throw the TV antenna or stand on one leg pointing the wired contraption as high as your arms can stretch while the signal comes and goes and your show is already half aired as this is a daily and frustrating thing for me when I want to just sit and relax to watch a 30 minute show. I start to think about the causes that could be interfering with the radio waves being blasted through the air. I say to myself, that darn airplane messed with the channel waves or maybe it was the 18-wheeler that just barreled down the road. Then I start wondering if it’s an issue that goes further than the closest tower or a rainy day. Maybe the cause is up in our atmosphere. We have had many space projects that launched satellites for specific jobs for our world. And with The Soviet Union launching the world’s first satellite in 1957, it must surely be congested.
NASA reports that there are more than 50,000 pieces of junk satellites, space craft remains and meteorite bits speeding around our Earth’s atmosphere at about 17,500 miles an hour. These numbers are expected to rise as these hunks of metal can become over congested and crash into each other. That could become a dangerous threat with many of these broken pieces that can’t be detected or tracked as they could fall back down to Earth.
Hopefully the people who work for the US Department of Defense can keep a clear eye out for these dangers as they maintain logs of all objects that are larger than a softball that are and will be in the Earth’s orbit. It is estimated that 150 tons of space junk re-enters our atmosphere each year. Most of this junk will burn up before it slams into the ground or water. With about 50 years of technology explorations with space, more than 6,000 satellites have been blasted into the Earth’s orbit. More than 3.600 satellites remain in orbit with many of them making its way back to the Earth’s solid ground.
What happens to the satellite when it becomes non-use? China launched a missile in 2007 into the Earth’s orbit to strike down one of their non-working satellites. Their mission was a success. Their dead on target had an effect that scattered about 3,000 more pieces of space debris in the orbit. For me this is not a very good way to bring down the hunk of junk that was launched decades in the past, by creating more debris that can create more of chance of crashing into other space debris that is speeding about 26,000 mph and clogging the orbit. There are also space probes that have been launched and placed in the orbits of the moon, Mercury, Venus, Mars, Jupiter, Saturn and the sun. As well as on comets.
There are many different types of satellites that perform certain jobs such as the Geo Stationary Orbit Satellite, which orbits the Earth’s atmosphere above the equator. These satellites provide functions with television transmission, telecommunications and navigation. There are satellites that travel about 90 minutes to go around the Earth and are 300 – 800 km above the Earth’s surface and are called a Low Earth Orbit satellite. These quick moving metals are used to observe the Earth’s resources. The Polar Orbit satellites travel North and South in the Earth’s orbit rather than East to West, as most satellites travel. The Polar Orbit satellites are used to track the weather forecast daily. Global Positioning System satellites are the GPS systems that people rely on to obtain mapping information of where their location is.
Space X has submitted regulatory flings to possible launch nearly 12,000 satellites into the orbit by 2020. With more space junk and working gear that is pending to go up as it speeds around the Earth’s surface and can crash into each other creating a bigger mess, something needs to be done to bring the debris down safely. Until then, I will have to start learning how to be a contortionist with my TV antenna to get a semi-clear image to watch for about 30 minutes.
