Technical Break: How Rocket Launch Timing is Chosen Launching rockets to the ISS at specific times is crucial due to the station's orbital path and the need for precise alignment with the cosmodrome. The ISS orbits at 51.6 degrees at an altitude of about 400 km, completing an orbit every 92 minutes. To ensure successful docking, the launch must coincide with the ISS directly above the cosmodrome, minimizing orbital adjustments and fuel consumption. The "launch window" is a brief period when the station's orbit aligns with the launch pad. Missing this window could lead to significant delays of weeks for a super-short scheme or a couple of days for a two-day scheme, emphasizing the importance of precise timing for successful launches. Astronauts onboard can witness these launches from the station windows during these critical moments.
