U.S. Cargo Poised for Launch; Robotics, Health Checks for Crew

A U.S. rocket stands at its launch pad ready to launch an advanced space toilet and new science experiments toward the International Space Station tonight. Back on orbit, the Expedition 63 trio worked on robotics, health checks and housecleaning today.

NASA and its commercial partner Northrop Grumman are counting down to tonight’s liftoff of the Cygnus space freighter atop an Antares rocket at 9:38 p.m. EDT from Virginia. Cygnus is packed with nearly 8,000 pounds of crew supplies and station gear due for a robotic capture on Sunday at 6:10 a.m.

Commander Chris Cassidy and Flight Engineer Ivan Vagner will be at the robotics workstation Sunday morning monitoring the approach and rendezvous of Cygnus. Cassidy will then command the Canadarm2 robotic arm to grapple Cygnus when it reaches a point about 10 meters from the station. Afterward, engineers on the ground will take over the Canadarm2 and remotely install Cygnus to the Unity module where it will stay until mid-December.

During Thursday morning, Cassidy installed a new robotic 4K camera that looks outside a Kibo laboratory module window at the Earth below. Called Avatar-X, the camera demonstrates how users on the ground can remotely control the camera to view Earth or practice telemedicine in remote locations.

Next, Cassidy strapped himself into an exercise bike with assistance from Vagner for a periodic health check. Vagner spent the rest of the day on photography inspections and plumbing tasks. Veteran cosmonaut Anatoly Ivanishin took the morning off before spending the afternoon cleaning the ventilation system and researching how multi-cultural crews communicate.

U.S. Cargo Mission Nears Launch; More Leak Checks and Research

U.S. Cargo Mission Nears Launch; More Leak Checks and Research

Expedition 63 Commander Chris Cassidy is at work inside the Kibo laboratory module from JAXA (Japan Aerospace Exploration Agency).

The Expedition 63 crew continues preparing for Sunday’s scheduled space delivery of nearly 8,000 pounds of supplies and gear aboard Northrop Grumman’s Cygnus space freighter. As usual, advanced space science rounded out the day’s activities inside the International Space Station. The crew also continues work to try and isolate the precise location of an air leak that was recently isolated to the Zvezda Service Module.

An Antares rocket stands at its launch pad in Virginia ready to carry the Cygnus resupply ship to space when it launches on Thursday at 9:38 p.m. EDT. About nine minutes later, Cygnus will reach Earth orbit heading towards the space station for a Sunday arrival and robotic capture at 6:10 a.m.

Commander Chris Cassidy and Flight Engineer Ivan Vagner continued practicing their robotics skills Wednesday afternoon on a computer. The duo will be on deck inside the cupola Sunday morning ready to command the Canadarm2 robotic arm to reach out and grapple Cygnus. Ground controllers will take over the Canadarm2 afterward and remotely install Cygnus to the Unity module about two hours later.

Cassidy started the day working inside Japan’s Kibo laboratory module setting up experiment hardware that enables science to take place outside the orbiting lab. The veteran astronaut also spent a few moments on light plumbing duty as he serviced the urine processing assembly located in the Tranquility module.

The two Russian cosmonauts, including three-time station resident Anatoly Ivanishin, focused on their complement of space research and lab maintenance throughout the day. The duo joined each other first for a space communications study utilizing a variety of photography and audio hardware. Next, Ivanishin moved to narrow the source of an air leak utilizing an ultrasonic leak detector. Vagner checked radiation measurements then swapped camera lenses and activated hardware for a pair of Earth observation studies.

UPDATE: Roscosmos has released new information, further isolating the leak location to the transfer chamber in the Zvezda Service Module. Additional leak detection operations will continue using the ultrasonic leak detector.

In terms of design, the Zvezda Service Module consists of four sections: three pressurized (Transfer Compartment, Working Compartment and Transfer Chamber) as well as the unpressurized Assembly Compartment housing the integrated propulsion unit.

The leak, which has been investigated for several weeks, poses no immediate danger to the crew at the current leak rate and only a slight deviation to the crew’s schedule.
