If you go out and carefully study the how to get songs on your ipod shuffle near dusk or dawn, and you have relatively dark skies, the odds are that you should not have to wait more than 15 minutes before you see one of the more than 35, satellites now in orbit around Earth.
Most of these "satellites" are actually just " space junk " ranging in size from as large as 30 feet, down to about the size of a softball. Try our Satellite Tracker from N2Y0. And in fact most satellites -- especially the bits of debris -- are too faint to be seen with the unaided eye.
But depending on who's counting, several hundred can be spotted with the unaided eye. These liok the satellites that are large enough typically more than 20 feet in wjat and low enough to miles above Earth to be most readily seen a sunlight reflects off them. On-orbit construction of the station began inand is scheduled to loom complete bywith operations continuing satlelites around how to look up cell phone carrier from number More than four times as large wht the defunct Russian Mir space station, the completed International Space Station will ultimately have a mass of about 1, pounds how to teach kindergarten at home and will measure feet across and feet long, with almost an acre of solar panels to provide electrical power to six state-of-the-art laboratories.
Presently circling the Earth at an average altitude of mi km and at a speed of 17, mi 27, km per hour, it completes Because of its size and configuration of highly reflective solar panelsthe space station is now, by far, the brightest man-made object currently in orbit around the Earth. On favorable passes, the space station can appear as bright as the planet Venus, at magnitude Some have made estimates as bright as magnitude -5 or -6 for the station smaller numbers represent brighter objects on this astronomers scale.
And as a bonus, sunlight glinting directly off the solar panels can sometimes make the ISS appear to briefly "flare" in brilliance to as bright as magnitude -8; more than 16 times brighter than Venus! Along with the ISS, you can also look for China's Tiangong-1 space laboratory, which has hosted visiting crews on Shenzhou spacecraft wht recent years. Also visible to the naked eye is the Hubble Space Telescope. But ,ook could potential be visible under the best observing conditions.
During the northern summer, when the nights are the shortest, the time that a satellite in a low-Earth-orbit like the ISS can remain illuminated by the sun can extend throughout satelkites night - a situation that can never be attained during other times of the year. Because the ISS circles the Earth about every 90 minutes on average, this means that it's possible to see it not just on one singular pass, but for several consecutive satelliyes.
Moreover, because the ISS revolves satelkites the Earth in an orbit that is inclined In the first case we'll call it a "Type I" passthe ISS initially appears over toward the southwestern part of the sky and then sweeps over toward the northeast. About seven or eight hours later, it becomes possible to see a second type of pass we'll call it "Type II",ike this time with the ISS initially appearing over toward the northwestern part of the sky and sweeping over toward the southeast.
Type I passes will initially be visible in the morning hours, prior to sunrise. By early July, Type I passes will be visible during the evening hours, just after sunset, while Type II passes will be occurring in the early morning.
By late July, visibility of the Type II passes will have shifted into the evening hours. So what is the viewing schedule for your te hometown? You can easily find out by visiting one of these four popular web sites:. Each will ask for your zip code or city, and respond with a list of suggested waht times.
Predictions computed a few days ahead of time are usually accurate within a few minutes. However, they can change due to the slow decay of the space station's orbit and periodic reboosts to higher ln.
Check dhat for updates. Some passes are superior to others. If the ISS is not predicted to get much higher than degrees above your local horizon, odds kike that it will not get much brighter than second or third magnitude degrees is roughly equal to the width of watellites fist held at arm's length. In addition, with such low passes, the ISS will likely be visible for only a whaat or two.
Conversely, those passes that are higher in the sky — especially those above degrees — will last longer and will be noticeably brighter. The very best viewing syk are those that take the ISS on a high arc across the sky about 45 to 60 minutes after sunset, or 45 to 60 minutes before sunrise. In such cases, you'll have it in your sky upwards to four or five minutes; it will likely get very bright and there will un little or no chance of it encountering the Earth's shadow.
While the ISS looks like satellitws moving star to the unaided eye, those who have been able to train a telescope on it have actually been able to detect its T-shape as it has whizzed across their field of view. Some have actually been able to track the ISS with their scope by moving it along the projected path.
Those who have gotten a good glimpse describe the body of the Space Station as a brilliant white, while the solar panels appear a coppery red. For evening passesthe ISS will usually start out rather dim and then tend to grow in brightness as it moves across the sky. In contrast, for the morning passes, the ISS will already be quite bright when it first appears and will tend to fade somewhat toward the end of its predicted pass.
This is due to the change jn the angle of how to do a back bend kick over hitting the vehicle. Lastly, remember that in certain cases, the ISS will either quickly disappear when it slips into the Earth's shadow during evening passes loook quite suddenly appear when it slips out of the Earth's shadow during morning passes.
This becomes increasingly more likely for passes that take place more than 90 minutes after sunset or more than 90 minutes before sunrise.

How do Starlink satellites work?

Apr 21, · After dusk and before dawn, when the Sun has dipped just below the horizon, the satellites reflect the Sun’s light back onto the ground, making them shine quite brightly. As Author: Jonathan O'callaghan. May 26, · To the eye, the 60 satellites appear as a "moving train" of moderately faint stars generally in the magnitude +4 to +5 range, although some Estimated Reading Time: 6 mins.
What's going on? The lights appear in groups of up to 60 in a long line. There have been numerous reports from places like the U. Of course. But fear not. These lights are actually satellites, launched into space by the U. And they're a bit controversial. The satellites are part of something called Starlink. This is a project by SpaceX to launch thousands of satellites into orbit, and beam the internet to Earth from space. SpaceX hopes to use this to fund missions to Mars.
Since the first launch in May , SpaceX has launched about of these satellites. Each weighs about kilograms and is roughly the size of a flattened car, with a large solar panel that reflects sunlight. They plan to operate 12, Starlink satellites in orbit, and potentially up to 42, This is known as a mega constellation. The satellites then use their onboard ion engines to raise their altitude up to their operational orbits of between and kilometers.
This can take several months to do. During these months, the satellites can appear very visible in the night sky when they fly over your location because of their reflective surfaces.
As they pass overhead, they appear like a bright train of lights as the satellites follow one after the other in orbit. People will then pay a fee to access the service, with speeds estimated to be slower than fibre broadband but faster than existing satellite internet services. However, people have raised concerns about the number of satellites SpaceX is launching.
Today only about 2, active satellites orbit Earth; SpaceX will increase this by six times, and possibly by 21 times. This poses a considerable risk for satellites colliding in Earth orbit. If two satellites collide, they can explode and produce thousands of small pieces of debris. This happened in between a U. Each of these pieces of debris can then also impact other satellites. Some people are worried we are putting too many satellites in orbit artist's impression, not to Another concern is that the satellites are very bright, outshining 99 percent of all other satellites in the night sky.
Because of this, astronomers have reported that the satellites are hampering their ability to study the universe. The satellites can appear as bright streaks in telescope images, ruining observations of galaxies and stars. With many more satellites set to be launched, astronomers have raised concerns about the number of satellites that will be visible in the night sky.
By some estimates, hundreds of Starlink satellites could be constantly visible in the night sky from any location on Earth. This could ruin the natural beauty of the night sky , and make astronomy much more difficult.
Currently there are no laws or regulations that protect the aesthetic of the night sky. But some people are looking to change that, and potentially take legal action against SpaceX. Regarding collisions, its says each of its satellites is equipped with an automated system to dodge other satellites.
However, in September this system failed, leading to a close call with a European science satellite. The company also says it is trying to make the satellites less bright. In January , it launched a Starlink satellite that had been coated in a darkened paint, to try and lower its reflectivity.
Early results suggest that, when it reached its operational orbit, this satellite did appear dimmer than other Starlink satellites.
However, it still appeared bright in the months it took to reach this orbit. The company is also working with astronomy groups to try and figure out ways to lower the impact of Starlink satellites on the work of astronomers. Elon Musk, however, has said he thinks there will be "zero" problems.
Elon Musk does not think Starlink satellites will be a problem for astronomy. There are some arguments that many of the problems with the satellites should have been sorted out before SpaceX started launching them.
However, for the time being, there are no rules or regulations stopping SpaceX from launching more and more Starlink satellites into orbit. Before the coronavirus pandemic emerged, the company planned to launch about 1, Starlink satellites by the end of , bringing its service online in the U.
That may now change. But for the time being, you will likely continue to see these trains of satellites in the night sky. You can use websites like Find Starlink or this handy tool to see when they will be visible above your location.
