As of May 4, 22 spacecraft are operating as part of the Russian GLONASS orbital constellation, the Information and Analytical Center for Coordinate-Time and Navigation Support said on Tuesday.

The United States sometimes forgets what the original reason was for sending troops to Afghanistan 20 years ago. This was stated by US Secretary of State Anthony Blinken in an interview with CBS News, which aired on May 2.

In the UK, parts of the hull of the promising Type 26 frigate were successfully docked. In the future, such ships will become one of the main combat units of the Royal Navy, and will also serve in the navies of partner countries.

Scientists from St. Petersburg at the State University of Technology and Design have developed a unique thermal insulation material with record fire-resistant and high-temperature performance. The basis for its manufacture is a mullite – silica fiber, which has the highest fire resistance and low thermal conductivity.

Since December last year, the New York Police Department (NYPD) has decided to use a modified Spot robot to perform explosive disposal missions so as not to endanger police officers. It was used several times to check the interior of a home that had been burglarized before police officers entered.

The US Army is developing the a-shape (alpha-shape) technique, which will ensure the joint work of several robots in conditions of poor communication between them or even complete lack of it. It will help groups of autonomous robots achieve their goals without interfering with each other and without duplicating actions, even though they will not be able to communicate with each other.

A recent study, the results of which are published in the journal Notices of the Royal Astronomical Society: Letters, found that the ever-growing mass of space debris in low-Earth orbit creates another unexpected problem. The fact is that the sunlight reflected from it, falling on the Earth, makes it difficult for astronomers to observe the stars.

Engineers and scientists are celebrating the setting of a new historical record – for the first time, the creation of human hands has accelerated to a speed of more than half a million kilometers per hour. The solar probe "Parker" is currently moving at a speed of 532,000 km/h and makes its eighth orbit around our star. Its onboard instruments actively collect information about magnetic fields, high-energy particles, and take pictures of the Sun.

The next prototype of the American Starship spacecraft, being developed for manned flights to the Moon and Mars, can be launched in a test suborbital flight on May 4 or 5, the specialized website Next Spaceflight reported.

Both subsequent launches will be commercial. They will be produced in May and July.

The work with the two Fregat upper stages is carried out by specialists at the Amur Vostochny cosmodrome. One of them is filled with fuel components and compressed gases at the filling and neutralization station.

The Russian exercises near the Ukrainian borders have excited everyone. But the giant NATO exercises "Defender of Europe-21", sometimes taking place very close to the borders of Russia, for some reason do not bother anyone. NATO, led by the United States, wants to take Russia into the ring. It is a shame that Sweden is also following their lead, the author believes.
