I saw a note that an ISS reboost of 7.5 km occurred yesterday. I'm confused because there was a DEBOOST (~1.5 km by a Soyuz) earlier in the week in preparation for the TMA-19 docking. Can someone explain the logic because this seems like a waste of valuable prop. I know orbital mechanics can be complicated but I'm really confused
Deboost by a Soyuz? Really?
According to my list, it will be "only" the 99th...http://www.kosmonavtika.com/vaisseaux/mks/missions/tous.htmlWho is right ??
