The increase in the number of satellites poses a threat to astronomy
it has been three years since SpaceX launched the first batch of Starlink Internet communication satellites. Among them, more than 2300 are now orbiting the earth, accounting for about half of the earth’s orbiting satellites. This has also led astronomers to worry about the track stripes left by the satellite running in the night sky. And in the next few years, tens of thousands of new satellites may be launched. starlink satellite scribes (vertically) a time-lapse photograph in the night sky near Carson national forest, New Mexico.

SpaceX carpool mission transporter-5 was completed and 59 small satellites were sent into space
According to the information from it house on May 26, at 2:35 a.m., SpaceX successfully carried out the transporter-5 mission using Falcon 9 at slc-40 of Cape Verde air force base, and sent 59 spacecraft, including cube satellite, microsatellite, non deployed managed payload and orbital transmission vehicle, to SSO orbit. About 8 and a half minutes after takeoff, the first stage booster successfully landed in cajiao 1 landing area; After about 1.5 hours, 59 cubes separated smoothly and entered 525 × 535km× 97.5º Solar synchronous orbit; The second stage of…
American satellites found a strange phenomenon. The Pacific Ocean was dark and floating towards China, four times the size of South Korea
American satellites found a strange phenomenon. The Pacific Ocean was dark and floating towards China, four times the size of South Korea Although human beings are developing faster and faster, now human beings can rush out of the earth. At present, there are more than 1000 satellites floating over the earth, most of which are from the United States. It can be seen that the title of the United States is not in vain! However, China knows that the purpose of each man-made satellite is different. Many of them can…

Space watch uses satellites to detect strong storms
May 15, 2022 May 15, 2022 On the morning of May 15, 2022, a supercell thunderstorm swept across the Great Plains. They brought hail, lightning, strong winds and downpours to parts of Kansas, Oklahoma, Missouri and Arkansas. The moderate resolution imaging spectrometer NASA’s Terra satellite captured this natural color image of a series of strong thunderstorms extending from eastern Kansas to Little Rock, Arkansas. The weather front includes multiple storm unit pullovers and cirrus plumes on the anvil, which are the main signs of particularly severe storms Over the top…
During the upcoming spacewalk, Russia will launch six small experimental satellites on the international space station
According to special correspondent of Tass News Agency and astronaut Oleg • Atmiyev reported on May 18, In Russia’s upcoming spacewalk, the international space station will launch six small satellites as part of the radioskaf experiment. Preparations for the launch are under way. The spacecraft has been inspected and the battery has been charged. Image from: Google Russia’s next spacewalk is scheduled for this summer. Six yuzgu-55 nano satellites developed by the Institute of instruments and radio electronics of Southwest State University (yuzgu) were brought to the orbital station by…
Why can man-made satellites fly around the earth?
After the man-made satellite is launched into space and enters the predetermined orbit, it will begin to fly around the earth. But why can man-made satellites fly around the earth without falling down? This is because after the man-made satellite is launched, it will revolve around the earth at a particularly high speed, offsetting the earth’s gravity on it. According to scientists’ calculations, artificial satellites should reach a speed of at least 7.9 kilometers per second. This speed is called the surround speed, also known as the first cosmic speed….
