Russia launches Progress 70 and completes fastest docking ever

Today Russia launched their latest Progress spacecraft to the International Space Station. The spacecraft lifted off at 17:51 EDT and then used an accelerated approach to dock just 3h 40m later making this the fastest launch to docking ever for Progress.

This was the third time Russia had attempted this, however, the previous two times the launch vehicle experienced technical issues while on the launch pad and the launch was delayed. Due to these delays, there wasn’t another launch opportunity available that would allow the accelerated approach so they had to revert to the standard docking profile.

As with previous changes to the launch profile for Russian vehicles, they test with the cargo Progress vehicles before attempting the same with the crew vehicles where the accelerated docking has more benefits for the crew aboard due to how cramped it is inside.
