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...

The International Space Station is pictured orbiting Earth in October of 2018. Late Monday night, the Expedition 63 crew was awakened by flight controllers to continue troubleshooting a small leak on the International Space Station that appeared to grow in size. Ground analysis of the modules tested overnight have isolated the leak location to the main work area of the Zvezda Service Module. Additional work is underway to precisely locate the source of the leak. 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. NASA astronaut and station commander Chris Cassidy and Roscosmos cosmonauts Anatoly Ivanishin and Ivan Vagner were instructed to move into the Russian segment to collect data at various locations in the Russian modules. The size of the leak identified overnight has since been attributed to a temporary temperature change aboard the station with the overal...

A U.S. cargo mission will wait a couple of extra days for weather to clear before launching to resupply the International Space Station this week. Meanwhile, the Expedition 63 crew has resumed standard operations following a leak test over the weekend. Scattered thunderstorms and rain are predicted at the Wallops Flight Facility in Virginia where Northrop Grumman’s Cygnus resupply ship was originally targeted for liftoff Tuesday night. Mission managers rescheduled Cygnus’ launch for Thursday at 9:38 p.m. EDT setting its arrival and robotic capture at the station for Sunday at 5:20 a.m. NASA astronaut Chris Cassidy and cosmonaut Ivan Vagner practiced their robotics skills on a computer today to get ready to capture Cygnus with the Canadarm2 robotic arm on Sunday morning. Cassidy will lead the capture activities while Vagner monitors the U.S. spacecraft’s appr...

The Expedition 63 crew will stay in the Russian segment’s Zvezda service module during a cabin air leak test this weekend. As part of ongoing  work to isolate the source  of a slight increase above the standard cabin air leak rate, the Expedition 63 crew will once again spend the weekend inside the station’s Russian segment. All the space station hatches will be closed this weekend so mission controllers can again monitor the air pressure in each module with the goal of localizing the source of the increased rate. The test presents no safety concern for the crew. Commander  Chris Cassidy  and his crewmates  Ivan Vagner  and  Anatoly Ivanishin  will stay in the  Zvezda service module from Friday night into Monday morning. The crew will spend Friday gathering items for the weekend isolation before closing hatches throughout the station at the conclusion of their crew work day. from Space Station https://ift.tt/333KQl7

The high-flying plumber installed a cable that will power the advanced toilet sy...

The International Space Station is pictured orbiting Earth in October of 2018. Using the ISS Progress 75 thrusters and with NASA and Russian flight controllers working in tandem, the International Space Station conducted a 150-second reboost Tuesday afternoon at 5:19 p.m. EDT to avoid a possible conjunction with an unknown piece of space debris. Because of the late notification of the possible conjunction, the three Expedition 63 crew members were directed to move to the Russian segment of the station to be closer to their Soyuz MS-16 spacecraft as part of the safe haven procedure out of an abundance of caution. At no time was the crew in any danger. The maneuver raised the station’s orbit out of the predicted path of the debris, which was estimated to come within 1.39 kilometers of the station with a time of closest approach of 6:21 p.m. EDT. Once the avoidance maneuver was completed, the crew reopened hatches between the U.S. and Russian segments and resumed their regular activi...
