SpaceX was one and a half years ahead of the schedule for the deployment of Starlink satellites in orbit — the FCC demanded that 2204 satellites be put into operation by March 2024.
Currently, 2,941 satellites have been deployed — 66% of the total plan of 4,408 satellites. Of these, 2,383 are already in operation.
In total, the FCC ordered 4,408 satellites until March 2027. Easy
Scientists want to smash a satellite on an asteroid to change its flight path. This will be the first such experiment in the history of mankind. The clash is scheduled for September 27.
The object is located at a distance of 5.6 thousand light years from Earth in the direction of the constellation Cygnus
The James Webb Space Telescope has captured an image of the impressive concentric rings of light surrounding the binary star WR 140. According to astronomers, such an unusual appearance of the nebula is the result of the interaction of powerful stellar winds and dust thrown into space by the rapidly losing mass components of the system.
The stars in the WR 140 system rotate around each other in an elliptical orbit and at the moment of maximum convergence, when the distance between them is approximately 1.3 astronomical units, their powerful winds collide. As the substance cools, dust forms, which is then gradually blown out.
Close encounters of the system components occur once every eight Earth years, and each of them leads to the appearance of another dust ring. In total, there are 20 of them in the James Webb image, which means that the age of the outermost ring does not exceed 160 years.
The Voyager-1 and Voyager-2 space probes will have some systems disabled to extend their operability at least until 2030.
The fact is that the United States, together with European countries, plan to launch the Interstellar spacecraft into space in the early 2030s, which will partially duplicate the goals of the Voyager-1 and Voyager-2 missions.
Both probes were originally designed for five years of operation. However, thanks to the high-quality work of engineers, the devices work up to the present day.
According to some experts, the service life of the devices may end as early as 2025, because plutonium, which is used as fuel, decomposes too quickly.
Previously, the device was running on a special version of Windows 98 and was already preparing to complete its program. Scientists have found that it is too early for the probe to retire.
After the update, Mars Express will begin to cover a large area of the surface of Mars for study.
Scientists expect that using this device will allow them to detect and give more opportunities to search for water on the planet. In addition, the update will increase the battery life of the probe by five times.
Apollo 11 on the moon began researching the exact distance from Earth to the moon. To do this, they brought devices resembling small arrays of mirrors – they are called retroreflectors
Research using such a simple device continues to this day
Example: a neutron star whose diameter does not exceed ten kilometers can weigh as much as our sun.
If a person is (hypothetically) moved to the surface of this object, the astronaut’s weight will increase by one million tons at once.
Here are the things…
The effects of gravity on the moon would have created an eightfold orbit for her and perhaps she would often have been sucked into the donut hole.
Jupiter’s red great Spot is the largest atmospheric vortex recorded in the Solar System. This vortex was discovered more than 350 years ago, it is constantly changing in size.
At the very beginning, when observations began, the Red Spot already measured about 40 thousand kilometers in length and 13 thousand kilometers in width. Since the 1930s, its size has been decreasing: in 1979 it was 23,300 km, in 2014 – 16,500 km.
The wind speed is calculated inside the spot, it exceeds 500 kilometers per hour.
The problem existing in near-Earth orbit is space debris
129 million fragments are currently flying around our planet in orbit. Almost 34,000 or so, of which are 10 cm wide.
At the height of the ISS orbit, this debris moves around the Earth more than 7 km/sec — this is so fast that a collision with even a tiny fragment can put an end to the functioning of the ISS scientific station.
Note this hole in the outer skin of the ISS, obtained from a collision with an object the size of a grain of sand. It looks like just a collision with a grain of sand, but what if with 10 centimeter garbage?
The collision energy is due to the high velocity of the space object.
