Sputnik 1
en.m.wikipedia.org...
The R-7 core stage, with a mass of 7.5 tonnes and a length of 26 metres, also reached Earth orbit. It was a first magnitude object following behind the satellite and visible at night. Deployable reflective panels were placed on the booster in order to increase its visibility for tracking.[66] A small highly polished sphere, the satellite was barely visible at sixth magnitude, and thus harder to follow optically.[25] The batteries ran out on 26 October 1957, after the satellite completed 326 orbits.[68]
Most Sputnik spotters actually saw its rocket
Though Sputnik 1 was small, it was quite reflective and therefore visible from Earth through a pair of binoculars (and perhaps even with the naked eye, if you had good vision and knew exactly where to look).
Many people reported seeing the satellite overhead in late 1957, but experts think most of these sightings actually involved the R-7. The rocket's 85-foot-long (26 m) core stage also reached orbit, and it was covered with reflective panels to make tracking it easier. This rocket body fell back to Earth on Dec. 2, 1957, according to Zak.

The front cover of the 1979 Neiman-Marcus Christmas catalog featured the first home satellite TV stations on sale.[4] The dishes were nearly 20 feet (6.1 m) in diameter.[5] The satellite dishes of the early 1980s were 10 to 16 feet (3.0 to 4.9 m) in diameter[6] and made of fiberglass with an embedded layer of wire mesh or aluminium foil, or solid aluminium or steel.[7]

How to cast a wider net for tracking space junk
There are only so many hours of the day you can use to track orbital debris. Some scientists think they’ve found more hours.

I think our views of space need to go more towards Einstein's relativity theory
Einstein's Relativity and Everyday Life
By Clifford M. Will
To determine its location, the GPS receiver uses the time at which each signal from a satellite was emitted, as determined by the on-board atomic clock and encoded into the signal, together the with speed of light, to calculate the distance between itself and the satellites it communicated with. The orbit of each satellite is known accurately. Given enough satellites, it is a simple problem in Euclidean geometry to compute the receiver's precise location, both in space and time. To achieve a navigation accuracy of 15 meters, time throughout the GPS system must be known to an accuracy of 50 nanoseconds, which simply corresponds to the time required for light to travel 15 meters.
But at 38 microseconds per day, the relativistic offset in the rates of the satellite clocks is so large that, if left uncompensated, it would cause navigational errors that accumulate faster than 10 km per day! GPS accounts for relativity by electronically adjusting the rates of the satellite clocks, and by building mathematical corrections into the computer chips which solve for the user's location. Without the proper application of relativity, GPS would fail in its navigational functions within about 2 minutes.
So the next time your plane approaches an airport in bad weather, and you just happen to be wondering "what good is basic physics?", think about Einstein and the GPS tracker in the cockpit, helping the pilots guide you to a safe landing.

Tracking Sputnik I’s Orbit
distributedmuseum.illinois.edu...
Sputnik I was launched by the Soviet Union on October 4, 1957, surprising the United States. By the evening of that same day, Astronomy department faculty and students gathered in the basement of the Observatory to begin making observations as the satellite passed over Urbana.
During the previous year the United States was gearing up to launch its own satellites and deployed Minitrack, a worldwide array of radio interferometer stations that could track the US satellite. Astronomy and Electrical Engineering Professor George Swenson obtained a Minitrack interferometer for the members of the University of Illinois Astronomical Society.
On the night of October 4th, students quickly assembled the antennas in the south yard of the Observatory. Sputnik transmitted its signal on a different frequency, but Swenson was quickly able to obtain another receiver and the students began recording the signals from “an enormous lavatory roll,” in the south yard. The interferometer made crude position measurements of Sputnik along with Doppler tracking data. Students also made visual observations using other instruments, such as theodolites, astronomical clocks, and WWV time signal receivers available at the Observatory.
Astronomers were among the few who knew celestial mechanics, so department chair George McVitte and astronomers Stanley Wyatt and Ivan King used the data to derive Sputnik’s orbital elements, with help from mathematician Donald Gillies and physicist James Snyder, who programed the ILLIAC I computer. The result was an ephemeris, or astronomical data set describing the orbit and position of the satellite in the sky, within two days of its launch and published in Nature by November of 1957.

Electronics engineers at the 1957 National Electronics Conference in Chicago set up equipment to listen for signals from Sputnik 1.

How tracking Sputnik inspired GPS
www.theglobeandmail.com...
The night after Sputnik's historic launch on Oct. 4, 1957, scientists at the Massachusetts Institute of Technology set out to chart the satellite's precise orbit in the sky by tuning into the "beep-beep-beep" of its radio signal.
As the satellite approach overhead, the frequency of the single increased, and as it got further away, the frequency decreased. Or put another way, the signal seemed to become stronger as satellite got closer and then weaker as the spacecraft receded in the distance- a phenomenon known as the Doppler effect.
It was readily apparent to the scientists that satellite signals could be used for a sophisticated space-based navigational and guidance system. Just as you could use the Doppler effect to pinpoint the location of a satellite flying overhead, you could also employ satellite signals to find your location on the ground. With such beckons in the sky, ships would always know their precise position at sea, troops could manoeuvre on the ground and bombs could be guided to their targets with deadly accuracy.

What would the average decibel level be at the launch area, compared to elsewhere? So what are you talking about 'sound' for?
And of course, they use 'falling debris' as their great excuse for it, why do you think they designed rockets with 'booster engines', and so forth, in the first place?
Their main power, and main fuel source, is obviously from the massive 'booster' engines, attached to their sides, which drops after the first 3-4 minutes, at low altitudes, as they fly out of all view, over the ocean!
What would fuel these rockets after they drop their tanks, booster engines, after 3-4 minutes?
Look at when, and where, they always drop boosters, etc..
They give us a show, a spectacle, to see, and be amazed by, which is a rocket launching from the Earth, going straight upward, in the sky, and that's a very, very dramatic, powerful display to see, and film, which sells the dream, the fairy tale, the fantasy, is a reality, without any proof.
If anyone wishes to believe it's about safety, they wouldn't allow people to the launch areas, or near to them.
They have always restricted us from those areas, to keep it a grotesque secret.

With there being so many different ways to prove objects have been placed in orbit by rocket than Turbos very limited acceptance that turbo will label CGI is TOTAL BS
To excuse why rockets veer off in a horizontal path, when they're going up into 'orbit', or 'space', they said it was for gaining more and more speed, from flying an 'orbit' around Earth, at a lower altitude, than a normal 'orbit' is, while in 'space'.
'Orbit' is where you gain super-duper 'speed', in a rocket, because they say it does, so it must be true, right? No reason to lie about that, is there? So it's true, if there's no reason they'd lie about it.
The satellite flew at a speed of 18,000 miles per hour and orbited Earth in a little more than an hour and a half. It traveled a total of 43 million miles in 1,440 orbits before it fell back to Earth in January of 1958.

What the duck does your rant have to do with....
The rocket placing the first satellite Sputnik into orbit was observed in flight over North America.
That rocket placed objects in the sky, changing the “heavens”
Sputnik could be seen around sunset and sunrise with a pair of binoculars.
One of the stages of the rocket could be seen by the naked eye orbiting the earth.
Sputnik’s orbit was tracked by its radio broadcasting.

The time to tune in to Sputnik as it flew over the USA was limited because the signal would be blocked by the curvature of the earth.
By the way people could tune in to Sputnik, and the way the signal was blocked by the earth. It’s proven Sputnik orbited the earth, and the earth is spherical. Along with visual evidence of its orbit, and man can change the heavens by adding artificial satellites.

They are all liars, caught in lies, and faking things, some of which are hilariously bad fakes, that's the only reality found here. And we have never seen a rocket from 100-300 miles off the coast, because it's for 'our safety', right?
Sad, very sad.
