Nearly three months after delivering several tons of scientific experiments and supplies to the International Space Station, Northrop Grumman’s autonomous Cygnus cargo craft is scheduled to depart the International Space Station on Monday, May 11.

Live coverage of the spacecraft’s release will air on NASA Television and the agency’s website beginning at 11:45 a.m. EDT, with release scheduled for 12:08 p.m.

Flight controllers on the ground will send commands to robotically detach Cygnus from the Earth-facing port of the Unity module, maneuver it into place, and release it from the Canadarm2 robotic arm. Station commander Christopher Cassidy of NASA will monitor Cygnus’ systems as it moves away from the orbiting laboratory.

Dubbed the “SS Robert H. Lawrence,” Cygnus arrived at the station Feb. 18 for the company’s 13th cargo mission with about 7,500 pounds of supplies and science experiments ranging from research with cell cultures and bone loss to demonstration of a new miniature scanning electron microscope (SEM) with spectroscopy. Cygnus launched on Northrop Grumman’s Antares rocket from NASA’s Wallops Flight Facility on Wallops Island, Virginia.

Northrop Grumman’s Cygnus resupply ship is packed for departure on Monday and will continue more science before its ultimate demise at the end of May. Meanwhile, two Expedition 63 Flight Engineers are maintaining International Space Station operations as the Commander takes a break today.

NASA astronaut Chris Cassidy is relaxing today ahead of this weekend’s activities to ready a U.S. space freighter for its robotic release on Monday at noon EDT. NASA TV will begin its live coverage of the cargo ship’s release from the Canadarm2 robotic arm beginning at 11:45 a.m.

The space veteran spent the week loading up the Cygnus space freighter with trash and preparing it for more science. Shortly after its departure, a controlled fire will be lit inside Cygnus for ongoing research into space fire safety. Next, tiny space research satellites, also known as CubeSats,  will be deployed outside the vehicle to improve space communications and GPS mapping technology.

Robotics controllers also attached the popular, but now-defunct HDEV (High Definition Earth Viewing) experiment on the outside of Cygnus for disposal. HDEV reached its end-of-life last year after five years in service providing live views of Earth to over 300 million viewers. The U.S. cargo craft will reenter Earth’s atmosphere at the end of the month for a fiery, but safe disposal above the South Pacific.

Cosmonauts Anatoly Ivanishin and Ivan Vagner started Friday studying how the heart adapts to a specialized suit that reverses the pooling of blood and water in a crewmember’s head caused by microgravity. They also took turns with an ongoing study that seeks to improve the detection and location of Earth landmarks for photography.

Ivanishin, a veteran of two previous station missions, then updated station inventory with the new cargo recently delivered aboard the Progress 75 cargo ship. Vagner, a first-time space flyer, collected radiation measurements and inspected the Zvezda service module’s windows.

The Expedition 63 crew will monitor the departure of an American resupply ship on Monday and welcome a Japanese cargo craft when it arrives two weeks later. Meanwhile, the three International Space Station residents are configuring the orbital lab for the spaceship activities and continuing microgravity science.

Northrop Grumman’s Cygnus space freighter is nearing the end of its stay attached to the Unity module. Robotics controllers on the ground will command the Canadarm2 robotic arm to detach Cygnus from Unity then release the U.S. cargo craft on Monday noon EDT. NASA Commander Chris Cassidy will finalize the installation of the SlingShot small satellite deployer on Cygnus’ hatch on Sunday.

NASA TV will begin its live broadcast of Cygnus’ release and departure at 11:45 a.m. on Monday. Cygnus will reenter the Earth’s atmosphere over the south Pacific for a safe, but fiery destruction at the end of the month.

Japan is targeting May 20 for the launch of its ninth station cargo mission aboard the H-II Transfer Vehicle-9 (HTV-9) resupply ship. The HTV-9 will launch from the Tanegashima Space Center and a take five-day trip to the orbital lab. It will be captured with the Canadarm2 and installed to the Harmony module for a two-month stay.

NASA Commander Chris Cassidy is setting up HTV-9 communications gear today inside the Kibo laboratory module from JAXA (Japan Aerospace Exploration Agency). The Proximity Communication Systems (PROX) sends and receives spacecraft location and speed data during approach and rendezvous operations.

The two cosmonauts continued their set of maintenance and science duties today over in the station’s Russian segment. Anatoly Ivanishin picked up a camera for more photo inspections in the Pirs and Poisk modules. The veteran cosmonaut then serviced power tools and life support gear. Ivan Vagner started his day cleaning vents and filters. In the afternoon, Vagner photographed the effects of Earth catastrophes and studied ways to improve the identification and location while picturing targets on the ground.
