An uncrewed Russian Progress 78 spacecraft arrived at the International Space Station’s Poisk module on the space-facing side of the Russian segment at 8:59 p.m. EDT, two days after lifting off from the Baikonur Cosmodrome in Kazakhstan Sunday, Tuesday June 29 at 7:27 p.m. (4:27 a.m. Wednesday, June 30, Baikonur time). The spacecraft were flying over southeast Pacific Ocean off the coast of Chile at the time of docking.

Carrying more than 3,600 pounds of food, fuel, and supplies for the Expedition 65 crew, the Progress 78 resupply spacecraft will spend almost five months at the station. The cargo craft is scheduled to perform an automated undocking and relocation to the new “Nauka” Multipurpose Laboratory Module in late October. Named for the Russian word for “science,” Nauka is planned to launch to the space station in July.

  1. I did not understand why there is no reason mention about arriving at ISS after 2 days, when it takes only 5 hours or more ,as I have learned from other launches.
    Is this because the docking space unprepared or missing the right cycle ?

    1. The ISS Progress 78 cargo craft launched the same day the Cygnus resupply ship departed the space station. As a result, a same-day docking for the Progress 78 was prohibited and required a two-day rendezvous.
