Pre-launch activities


New Progress launched
Progress M1-1 successfully replaced Progress M-42 at Kvant's docking port. New Progress is ready to re-pressurize Mir as soon as the pressure drops under 500 mm Hg, but it's still 525.


Mir orbit raised
Now we can say that Progress M1-1 saved Mir. If its two tons of fuel weren't put in action before February 20, fast decay of Mir would become irreversible.
