Mission managers are waiting for the weather to clear up at Wallops Flight Facility in Virginia so they can launch the Cygnus space freighter from Northrop Grumman. Cygnus is now targeted to lift off Friday at 3:43 p.m. EST atop an Antares rocket.
Cygnus will arrive at the space station on Sunday packed with new science experiments, crew supplies and station hardware. NASA Flight Engineer Andrew Morgan will be in the cupola commanding the Canadarm2 robotic arm to reach out and capture Cygnus at 5:11 a.m. Robotics controllers will then take over and remotely command the Canadarm2 to install Cygnus to the Unity module where it will stay for three months.
NASA TV will cover all the launch, capture and installation activities live. View the NASA TV schedule here.
Morgan started his day replacing components inside an oxygen generator in the Tranquility module. Afterward, he serviced the Advanced Resistive Exercise Device that enables astronauts to maintain muscle strength during long-term space missions.
Jessica Meir of NASA worked throughout the day in Europe’s Columbus laboratory module. She was shifting cargo to access an area behind the Human Research Facility-2 rack. Once there, she installed cables that link to the Bartomoleo external payload facility on the outside of Columbus.
Commander Oleg Skripochka of Roscosmos began Tuesday transferring water from a docked Progress 74 cargo craft to a station tank. Skripochka, who is on his third station flight, then spent the afternoon cleaning cooling loops on a pair of Russian Orlan spacesuits.
