On this Tuesday, July 7th, between 20:55 and 21:00, the International Space Station will pass over the sky of Israel with a clarity that has never been seen before in Israel, thanks to its expansion and being gentle in the sunlight when it is already dark on the ground
This Tuesday, July 7, between the hours of 20:55 and 21:00, the International Space Station will pass over the sky of Israel in a clarity that has never been seen before in Israel. It will look like a very bright star flying at high speed in the sky (like an airplane) from southwest to northeast. See a picture from the Central Bank
The reason why the transits in the hours after sunset are the best hours for viewing the transits of the station and that they are the brightest lies in the fact that on the ground we see that the sun is already below the horizon, but at the cruising altitude of the station it is still above the horizon and illuminates the metal facility with its full power.
The station has recently undergone an upgrade that makes it the brightest object in the night sky other than the moon. As I recall, the upgrade now allowed 6 astronauts to stay in orbit (in place of 3 so far) of about 350 km above the Earth.
On July 11, the launch of the space shuttle Endeavor is expected for the STS-127 mission, the purpose of which is to continue assembling the International Space Station, filling its warehouse with supplies and replacing one of the crew members - Tim Corpetta will replace the Japanese Koichi Wakata.

Now for about two hours we looked at a very bright point in the sky that looks like a triangle in the binoculars similar to a space shuttle and around it 3 points at different distances that lit up in alternating colors (red, green). Is this a ferry? What is the reason that the object has not moved from its place until this second?

I took a picture with my cell phone if you want to see

It is important for me to point out that Yehuda's opinion is not only a minority opinion but is almost a singular opinion.
There is no physicist who thinks so because every physicist knows that the moon moves away from the earth because of the tides it creates on the earth since it is still rotating relative to it.
This is a phenomenon that can be proven even in Newtonian physics.
If the moon's orbit was lower than the orbit of the geostationary satellites, it would actually approach the earth for exactly the same reason.
Since it is further away - it continues to move away, while slowing down the Earth's rotation relative to it.
And I also think (in a minority opinion) that the general expansion of the universe is also expressed in the movement of the planets so that I think that the planets and also the moons actually move away from the body they revolve around. the universe.
Someone decided that the expansion of the universe is expressed only in galaxies, which is unacceptable to me.
Good night and hopefully we won't fall into the sun.

Moti:
All the answers to your question (13) as well as to many other questions you didn't dare to ask are here:
http://en.wikipedia.org/wiki/International_Space_Station
Anonymous (11):
It is not true that the mass of the Earth is decreasing because, beyond the fact that most spacecraft return and fall on it, asteroids and interstellar dust are also added to them (and at the same time part of the atmosphere also escapes into space).
In general, the mass of the earth remains more or less constant but that is only part of the story.
In fact, according to the laws of basic Newtonian mechanics, a planet's orbit does not change as a function of that planet's mass just as all geosynchronous satellites are at the same height above Earth regardless of their location.
According to Newtonian mechanics, the orbit of a planet can change gradually, but this is not the result of a change in its mass, but of the influence of tidal forces.
Another factor that affects the orbital changes is the friction with the interstellar dust.
Another factor is the gravitational pull exerted by other planets.
If you add to the picture the theory of general relativity and the energy lost in the form of gravitational waves, you come to the conclusion that even if as a result of tidal forces the planet is currently moving away from the sun, it will eventually fall on it.
All these - of course - are things you did not intend to ask about and I added them only so that it would not be implied from my claim that the Earth's orbit does not change (because it does change) but that the reason for the change is not the one you mentioned.
In general, every near-Earth satellite, such as the space station, flies at a height of several hundred kilometers above the earth's surface and its speed is about eight kilometers per second.
This is in contrast to communication satellites flying at an altitude of about thirty-five thousand kilometers above the earth's surface and a speed of one cycle in twenty-three hours and fifty-six minutes. These are located approximately above the equator.
Good Day
Sabdarmish Yehuda
I took a picture, but it turned out to be quite a crap shoot because it went by really fast and it was pitch dark.
I used a long exposure so it would show clearly but it came out of the wind like a comet
Kitzer was not a hit - think of an airplane only many times faster and brighter
Where can I see pictures of the transition?
Maybe someone here took a picture and can upload it to some website?
Thank you father D:
Let's hope to catch the ferry next time=[
What is the height and speed when passing over us??? Thank you for the report.
First of all, I also went outside and saw well up to the huge cloud in the northeast (observation point - Ramat Aviv C). When the station was at its height it was just like a lamp hanging in the sky.
Next time - on Thursday, closer to eight (starting at 20:07) but because of that they will probably see less well (there is still light). Here it is worth noting that the station passes a lot over Israel, but during the day it is difficult to see because of the sun and at night it does not reflect the sunlight, so the hours between day and night remain (both early in the morning and after sunset).
Hope you enjoyed the service.
Ugh.. I didn't see=[ I didn't find=[ I plowed in the sky for 10 minutes =[]
That came up
The mass of the earth decreases over time, because man sends satellites into space and thus reduces the weight of the earth.
This thing over time (when the amount of spaceships will increase) will be a stage where the distance between the Earth and the Sun will begin to decrease.
Because Earth's gravity has decreased?
We saw her
Most wonderful!
When is the next time?
I saw her, cool!
(: I saw the spaceship... ahhh what fun
Just saw it. great view!
What are the coordinates for the observation??
It's worth trying.. even though it will be difficult..
How can I identify the exact location of the station to start shooting?
By the way, if it is visible over Israel for 5 minutes, that means it will cross the entire country from the sun. It would be crazy to follow it in a circle, wouldn't it?
Cool.
I hope that tomorrow evening I can go up to a dark vantage point and see her.
To my father
Maybe you can get telescope photos of the station from Tel Aviv University's Mitzvah Wise Observatory
in Mitzpe Ramon (Dr. Noah Brosh) and present them here on the website. Successfully .
Hanan, please note:
It's not a UFO! It's the space station!
Thanks uncle!
Hope to watch and maybe I'll be able to take a picture!
