The Expedition 63 crew continues making ready for Sunday’s scheduled area supply of practically 8,000 kilos of provides and kit aboard Northrop Grumman’s Cygnus area freighter. As typical, superior area science rounded out the day’s actions contained in the International Space Station. The crew additionally continues work to try to isolate the exact location of an air leak that was not too long ago remoted to the Zvezda Service Module.

An Antares rocket stands at its launch pad in Virginia prepared to hold the Cygnus resupply ship to area when it launches on Thursday at 9:38 p.m. EDT. About 9 minutes later, Cygnus will attain Earth orbit heading in direction of the area station for a Sunday arrival and robotic seize at 6:10 a.m.

Commander Chris Cassidy and Flight Engineer Ivan Vagner continued practising their robotics expertise Wednesday afternoon on a pc. The duo will probably be on deck contained in the cupola Sunday morning able to command the Canadarm2 robotic arm to succeed in out and grapple Cygnus. Ground controllers will take over the Canadarm2 afterward and remotely set up Cygnus to the Unity module about two hours later.

Cassidy began the day working inside Japan’s Kibo laboratory module establishing experiment {hardware} that allows science to happen outdoors the orbiting lab. The veteran astronaut additionally spent just a few moments on gentle plumbing responsibility as he serviced the urine processing meeting positioned within the Tranquility module.

The two Russian cosmonauts, together with three-time station resident Anatoly Ivanishin, centered on their complement of area analysis and lab upkeep all through the day. The duo joined one another first for an area communications research using a wide range of images and audio {hardware}. Next, Ivanishin moved to slender the supply of an air leak using an ultrasonic leak detector. Vagner checked radiation measurements then swapped digital camera lenses and activated {hardware} for a pair of Earth statement research.

UPDATE: Roscosmos has launched new data, additional isolating the leak location to the switch chamber within the Zvezda Service Module. Additional leak detection operations will proceed utilizing the ultrasonic leak detector.

In phrases of design, the Zvezda Service Module consists of 4 sections: three pressurized (Transfer Compartment, Working Compartment and Transfer Chamber) in addition to the unpressurized Assembly Compartment housing the built-in propulsion unit.

The leak, which has been investigated for a number of weeks, poses no fast hazard to the crew on the present leak charge and solely a slight deviation to the crew’s schedule.
