NASA will Retire International Space Station in 2031

According to NASA, the International Space Station will continue its operation until 2031 and then crash into an uninhabited area in the Pacific Ocean known as Point Nemo. It will be replaced with three free-flying space stations to continue the work after ISS's retirement. NASA also selected Houston-based Axiom Space to provide the ISS's first commercial module.
The International Space Station was the brainchild of former US President Ronald Reagan, who in 1984 proposed building a permanently inhabited spacecraft in cooperation with a few other countries. In 1998, the first piece of the space station, a control module, was launched into space onboard a Russian rocket. About two weeks later, a crew onboard the US' Endeavour space shuttle attached the control module with another part, the Unity node.

Rogue Black Hole Spotted on its Own for the First Time

Astronomers may have for the first time detected and measured the mass of an isolated stellar-mass black hole, a new study finds.
Previous research suggested that when giant stars more than 20 times the mass reach the end of their lives, they usually die in catastrophic explosions known as supernovas, and their dense cores are expected to collapse to become black holes.

It is the first NRO mission that involved rocket landing. Rocket landing is also called vertical landing. It was launched from the Vandenberg Space Force base located in California. The NROL-87 is a US reconnaissance satellite. The Falcon rocket delivered the satellite at 512.7 km orbit. It was placed in a Sun Synchronous Orbit. It is also called helio synchronous orbit. It is a polar orbit. Here the satellite passes through the given point at the same local mean solar time.
