Russian Cargo Ship Leaves, Crew Tests Dragon’s Comfort Factors

July 8, 2020: International Space Station Configuration. Four spaceships are attached to the space station including the SpaceX Crew Dragon, the HTV-9 resupply ship from JAXA (Japan Aerospace Exploration Agency) and Russia’s Progress 75 resupply ship and Soyuz MS-16 crew ship.

Russia’s Progress 74 (74P) cargo craft departed the International Space Station today leaving four spaceships from the U.S., Russia and Japan parked at the orbital lab. It will be replaced in two weeks when the Progress 76 arrives to replenish the crew.

The 74P undocked today at 2:23 p.m. EDT after seven months attached to the Pirs docking compartment. The trash-packed resupply ship will descend into Earth’s atmosphere above the South Pacific for a fiery but safe demise. The 76P will take its place when it launches on July 23 at 10:26 a.m. and docks just three-and-a-half hours later to Pirs.

Four out of the five Expedition 63 crew members assessed comfort factors inside the docked SpaceX Crew Dragon today. This is a demonstration of the Crew Dragon’s habitability ahead of the SpaceX Crew-1 mission planned for later this year.

NASA astronauts Doug Hurley and Bob Behnken, who piloted the Crew Dragon, will be joined by station Commander Chris Cassidy and Flight Engineer Anatoly Ivanishin for the one-hour habitability test. The crew will arrange the cabin to suit the four space residents and report their comfort levels to engineers on the ground.

While they were setting up Crew Dragon for the test, the three NASA astronauts also had time for ultrasound eye scans, microfluid studies and orbital plumbing work. The two cosmonauts, including Flight Engineer Ivan Vagner, juggled a variety of Russian space research and tested Soyuz crew ship communications gear.

  1. Fascinating. I enjoy reading as much as i can about the ISS programme. Been hooked since the moon landing 1969, a visit to Cape Canaveral where I saw the final shuttle coming outof the hanger in 2011 and then a visit to the Johnson space centre in 2017. Thanks for all the information
    Regards Bob Scott

  2. Bravo pour l’amarrage de Crew Dragon à la Station Spatiale. Le confort n’a pas de prix. J’ai une pensée nostalgique pour la navette Atlantis et son oeuvre remarquable. Bonne chance au dragon pour son premier retour sur terre avec un équipage. Je tire aussi mon chapeau à la navette Soyouz et son extraordinaire fiabilité. J’espère que cette remarquable collaboration internationale se poursuivra avec la station orbitale lunaire. Je propose de la nommer LOFT (Lunar Orbital Foster Tank), avec tout le confort qui s’ensuit.

    1. The docked Soyuz crew ships can also be used as life boats in the event of an emergency. Today, three station crew members practiced an emergency evacuation inside the Soyuz MS-16 crew ship.
