US missile warning system's fifth satellite launched into orbit

8

The United States has launched the fifth GEO-5 missile warning system satellite into orbit. The withdrawal was carried out using an Atlas V launch vehicle.


The United Launch Alliance (ULA) Atlas V launch vehicle took place from the Cape Canaveral Cosmodrome in Florida at 13:37 PM ET on Tuesday, May 18, 2021. The rocket launched the GEO-5 spacecraft into orbit, which will be part of an early warning system for ballistic missile launches called SBIRS.

As follows from the satellite number, this is already the fifth device that will enter the constellation of satellites in geostationary orbit. They are designated "GEO". The system also includes a constellation of satellites in a high-elliptical orbit, they are designated "HEO". This constellation includes military satellites with a tracking system as a payload. Thus, the basis of the system is made up of vehicles in geostationary orbit.

In total, according to available information from open sources, the American SBIRS early warning system should include 10 spacecraft of both groups, in the proportion: 6 - "GEO" and 4 - "HEO".

The GEO satellite is designed to last 12 years. The spacecraft weighs 4500 kg and carries two special infrared sensors capable of detecting rocket launches at different points on the Earth. The device was developed by Lockheed Martin.

    It is on the Atlas V that the RD-180s stand.

      Yeah. And the price tag swells out of the blue, because Boeing needs money, and there are no other people who want to invest in the stability of the corporation, except for their native state. The last commercial launches of Atlas are WorldView4 and ExoStar in 2016. After that, only the budget buys.

      Another launch is important today - TianZhou flies in 10 hours - https://go4liftoff.com/launch/long-march-7-tianzhou-2


      If it arrives, then the next crew is already on the space station in 3 weeks.

    Are all asteroid falls waiting?

    Yes .... In the near future, "Moscow traffic jams" await near-earth orbit, there is so much debris, but there are no space wipers from Central Asia ..... request
    Cases ....

      Our spacecraft ERS "Kanopus-V" No. 5 has just missed the Japanese "ASNARO". The distance between them was 200 meters.
