The hatches are open between Northrop Grumman\u2019s second Cygnus XL cargo spacecraft and the International Space Station<\/a> following its robotic capture<\/a> and installation<\/a> on Monday. The Expedition 74<\/a> crew is now beginning to unload some of the new science and crew supplies delivered on Monday.<\/p>\n

NASA flight engineers Chris Williams<\/a> and Jack Hathaway<\/a> were the first crew members to enter Cygnus XL on Tuesday after a series of pressure and leak checks inside the spacecraft. They were joined soon after by flight engineers Jessica Meir<\/a> of NASA and Sophie Adenot of ESA (European Space Agency) transferring time critical research samples stowed in Cygnus\u2019 portable science freezers<\/a> for preservation in the station\u2019s MELFI<\/a> science freezers and the MERLIN<\/a> incubators.<\/p>\n

Among the several tons of cargo Cygnus XL delivered Monday are over 2,300 pounds of new research hardware and science experiments. The crew will soon begin exploring blood stem cells<\/a> to treat cancers and blood disorders, study ways to protect astronaut gut health<\/a>, observe proteins suspended in water<\/a> to advance pharmaceutical production, and install a quantum physics module to expand the abilities of the Cold Atom Lab<\/a>. Other gear delivered aboard Cygnus XL include an advanced exercise system<\/a> from ESA, new eye-imaging hardware, oxygen and nitrogen tanks to recharge spacesuits, and more<\/a>.<\/p>\n

Meanwhile, the Roscosmos Progress 93 resupply ship is nearing the end of its stay after seven months docked to the Zvezda service module\u2019s aft port. Cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, station commander and flight engineer, spent the day packing trash and obsolete equipment inside Progress before its departure later this month. The duo also configured the spacecraft\u2019s docking hardware for the upcoming undocking activities.<\/p>\n

Roscosmos flight engineer Andrey Fedyaev kicked off his shift collecting air samples inside Cygnus XL shortly after Williams and Hathaway opened the spacecraft\u2019s hatch to protect the station\u2019s environment. Fedyaev then spent the rest of his shift maintaining the Roscosmos segment\u2019s orbital plumbing and ventilation systems.<\/p>\n
