The 4th manned space race news and discussion
North Korea unlocks orbital maneuvers milestone
Malligyong 1-03 (2023-179A, 58400) is a North Korean military optical imaging satellite. Released from launch vehicle at 13:54 UTC on 21st November 2023. A series of daily orbit adjustments have been reported by the US military space tracking network CSpOC between 19th-24th February 2024.
The series of small orbital maneuvers between 19th-24th February 2024, raised Malligyong-1's perigee by nine kilometers, from 488 to 497 kilometers.
Commentary
This is the first time that a North Korean satellite has shown the ability to do orbital maneuvers, and to many dismayed western analysts this ability comes as yet another total surprise. But not for the serious OSINT and the readers of sinodefenceforum that knew orbital maneuvers are one of the many key breakthroughs pursued by North Korea and necessary before any orbital manned spaceflight could be unlocked.
Mono-propellant and bi-propellants thrusters
Dr. Hossein Samimi, director of the Iranian Space Research Institute, said in an interview with the institute's public relations reporter: "Engineering samples of mono-propellant and bi-propellant thrusters have been made in the Space Transportation Systems Research Institute of the Iranian Space Research Institute and have passed performance tests well."
In this interview, the director of the Iranian Space Research Institute explained that space systems such as satellites, spacecraft and satellites use special engines to move in space and control their position. In space applications, this type of engine is called a thruster. Features such as amplitude of thrust, the ability to turn on and off frequently, good controllability, and a long history of successful use in the world, have made these low-propulsion systems the most widely used thrusters in a variety of space missions.

This will be more than sufficient to replicate a Mercury-Redstone-type manned suborbital mission.
