Orbital ATK’s Antares rocket carrying the Cygnus cargo spacecraft lifted off at 4:44 a.m. EDT and is on its way to the International Space Station. At the time of launch, the space station was traveling at an altitude of about 250 miles, over the central south Atlantic.
An hour and half after launch, commands will be given to deploy the spacecraft’s UltraFlex solar arrays. Launch coverage will resume on NASA TV at http://www.nasa.gov/live at about 5:45 a.m. for solar array deployment, which is expected to last about 30 minutes.
A post-launch news conference will follow and is scheduled to begin on NASA TV at approximately 7:00 a.m.
The Orbital ATK Cygnus cargo craft that will resupply the Expedition 55 crew on the International Space Station rolled out to its launch pad Thursday night. Cygnus is now targeted to blast off atop the Antares rocket Monday at 4:39 a.m. EDT from Wallops Flight Facility in Virginia. NASA TV will begin its live broadcast of the launch Monday at 4 a.m.
Orbital ATK and NASA managers moved Cygnus’ launch to no earlier than Monday to support further pre-launch inspections and more favorable weather conditions. Monday shows an 80% probability of acceptable weather for launch.
Cygnus is packed with 7,400 pounds of new science experiments, crew supplies and space station hardware. It is scheduled to arrive Thursday at the space station for its robotic capture at 5:20 a.m. NASA TV will cover the approach and rendezvous activities starting at 3:30 a.m.
Three NASA astronauts, Scott Tingle, Ricky Arnold and Drew Feustel, have trained for weeks to get ready for Cygnus’ arrival on Thursday. Tingle will be operating the Canadarm2 from inside the Cupola and command the robotic arm to grapple Cygnus. Arnold will back him up on the robotics controls and Feustel will monitor Cygnus and it systems during its approach. Robotics engineers on the ground will then remotely install the commercial space freighter on the Earth-facing port of the Unity module later Thursday morning.
One of the new experiments being delivered aboard Cygnus to the orbital laboratory will study atoms frozen to a temperature 10 billion times colder than deep space. The Cold Atom Lab will observe the quantum phenomena possibly leading to advanced spacecraft navigation techniques and quantum sensors that can detect gravitational and magnetic fields.
Two NASA astronauts are finalizing their preparations ahead of Wednesday morning’s spacewalk to swap thermal control gear outside the International Space Station. The Expedition 55 crew also worked on biomedical operations, radiation checks and Cygnus communications gear.
Flight Engineers Ricky Arnold and Drew Feustel checked their tools and reviewed their procedures one last time today before tomorrow’s spacewalk. The pair will work for about 6.5 hours swapping a pair of thermal control devices, known as Pump Flow Control Subassemblies, which control the circulation of ammonia keeping external station systems cool.
The veteran spacewalkers will set their spacesuit batteries to internal power Wednesday at about 8:10 a.m. EDT signaling the official start of the 210th spacewalk in space station history. NASA TV will begin its live broadcast of the activities beginning at 6:30 a.m.
Science and maintenance are always ongoing aboard the orbital lab even despite the spacewalk and cargo mission readiness activities. Feustel and Japanese astronaut Norishige Kanai collected their biological samples this morning and stowed them in a science freezer for later analysis. Cosmonaut Oleg Artemyev explored cardiac bioelectric activity at rest. Commander Anton Shkaplerov collected radiation measurements from dosimeters he retrieved from the orbital lab’s U.S. segment.
Orbital ATK is getting its Cygnus space freighter ready for launch Sunday at 5:04 a.m. to deliver science, supplies and hardware to the Expedition 55 crew. Astronaut Scott Tingle checked out command and communications gear that will be used when Cygnus arrives four days later on Thursday for capture at 5:20 a.m.
Veteran astronauts Ricky Arnold and Drew Feustel will embark on the 210th spacewalk Wednesday at the International Space Station to swap out thermal control gear. The experienced spacewalkers have a combined 10 spacewalks between them with Feustel having conducted seven and Arnold with a total of three.
Flight Engineer Scott Tingle assisted the duo today getting spacewalk tools ready and recharging the U.S. spacesuits inside the U.S. Quest airlock. Tingle and Japanese astronaut Norishige Kanai will assist the spacewalkers in and out of the airlock Wednesday and guide the duo during their tasks.
Orbital ATK will launch their Cygnus space freighter on Sunday at 5:04 a.m. EDT to resupply the Expedition 55 crew just four days after Feustel and Arnold complete their fourth spacewalk together. After a four-day trip in space, Cygnus will deliver crew supplies, station hardware and experiments exploring a variety of subjects including life science and space physics.
Arnold and Tingle practiced the robotics maneuvers today on a computer they will use to capture Cygnus after its approach and rendezvous with the station on May 24 at 5:20 a.m. NASA TV will broadcast the Cygnus launch and capture activities live at the orbital laboratory.
International Space Station officials will preview a pair of upcoming spacewalks live on NASA TV Tuesday. Meanwhile, Orbital ATK is getting its Cygnus resupply ship ready for launch in less than two weeks while the Expedition 55 crew focuses on biomedical studies today.
Two NASA astronauts are going out for a spacewalk May 16 to swap out thermal control gear that circulates ammonia to keep station systems cool. Station experts will be on NASA TV beginning at 2 p.m. EDT Tuesday to preview next week’s spacewalk including a second spacewalk planned for June 14. Both excursions will be conducted by veteran spacewalkers Ricky Arnold and Drew Feustel.
Feustel and Arnold verified their spacesuits are sized correctly with assistance from astronauts Scott Tingle of NASA and Norishige Kanai from the Japan Aerospace Exploration Agency. Tingle also checked the batteries that power the U.S. spacesuits.
On May 20, just four days after the first spacewalk, Orbital ATK is planning to launch its Cygnus space freighter on a four day trip to the orbital laboratory. Cygnus will resupply the Expedition 55 crew with new science experiments, crew supplies, station hardware and gear that will be installed on the June 14 spacewalk.
Today’s science taking place onboard the station explored how microgravity affects blood pressure and blood vessels. Kanai started his day photographing his face to help scientists understand how the upward flow of fluids impacts intracranial pressure affecting a crew member’s eyes. He later attached sensors to his legs, scanned them with an ultrasound device and checked his blood pressure for the Vascular Echo study.
After delivering almost 7,400 pounds of cargo to support dozens of science experiments from around the world, the Orbital ATK Cygnus cargo spacecraft has departed the International Space Station. At 8:11 a.m., Expedition 53 Flight Engineers Mark Vande Hei and Joe Acaba of NASA gave the command to release Cygnus.
On Tuesday, Dec. 5, ground controllers used the Canadarm2 robotic arm to detach the Cygnus spacecraft from the Earth-facing side of the station’s Unity module. The spacecraft, which arrived at the station Nov. 14, then maneuvered above the Harmony module to gather data overnight that will aid in rendezvous and docking operations for future U.S. commercial crew vehicles arriving for a linkup to Harmony’s international docking adapters.
Experiments delivered on Cygnus supported NASA and other research investigations during Expedition 53, including studies in biology, biotechnology, physical science and Earth science.
Later today, Cygnus will release 14 CubeSats from an external NanoRacks deployer. Cygnus also is packed with more than 6,200 pounds of trash and other items marked for disposal during its destructive reentry Monday, Dec. 18.
The Cygnus launched Nov. 12 on Orbital ATK’s upgraded Antares 230 rocket from NASA’s Wallops Flight Facility in Virginia for the company’s eighth NASA-contracted commercial resupply mission.
The Orbital ATK Cygnus cargo spacecraft is set to leave the International Space Station on Wednesday, Dec. 6. NASA Television and the agency’s website will provide live coverage of Cygnus’ departure beginning at 7:45 a.m. EST. Cygnus arrived to the space station Nov. 14 with nearly 7,400 pounds of cargo to support dozens of science experiments.
At approximately 8:10 a.m., Expedition 53 Flight Engineers Mark Vande Hei and Joe Acaba of NASA will give the command to release Cygnus.
Earlier today, ground controllers used the Canadarm2 robotic arm to detach the Cygnus spacecraft from the Earth-facing side of the station’s Unity module.
This was Orbital ATK’s eighth contracted commercial resupply mission.
SpaceX has delayed the launch of its next Dragon resupply mission to the International Space Station to no earlier than Dec. 12. Back on orbit, the Cygnus cargo craft is getting ready to leave the orbital lab and an experimental module has its stay in space extended for at least another three years.
NASA and our commercial cargo provider SpaceX are targeting no earlier than Dec. 12 at 11:46 a.m. EST for their 13th commercial resupply services mission to the International Space Station. This new launch date takes into account pad readiness, requirements for science payloads, space station crew availability, and orbital mechanics. Carrying about 4,800 pounds of cargo including critical science and research, the Dragon spacecraft will spend a month attached to the space station.
Ground controllers uninstalled Cygnus from the Unity module Tuesday morning with the Canadarm2 and are conducting a series of communications tests to assist NASA’s Commercial Crew Program. Next, Vande Hei and Acaba will command the Canadarm2 to release Cygnus back into Earth orbit tomorrow at 8:10 a.m. EST where it will stay until Dec. 18.
BEAM, formally known as the Bigelow Expandable Activity Module, is staying attached to the station for another three years with a potential to stay an extra year after that. While BEAM transitions to its new role as a cargo hold, engineers will continue studying its ability to resist radiation, space debris and microbes. Bigelow Aerospace and NASA signed the contract extension in November to continue demonstrating the reliability of expandable habitat technologies in space.
The Expedition 53 crew is configuring the orbital complex for a pair of cargo missions and a crew swap in December. Two colorful soccer ball-sized satellites were also floating around inside the International Space Station being tested today.
SpaceX has announced it is now targeting Dec. 8 for the launch of its Dragon cargo craft to the space station’s Harmony module. Among the variety of crew supplies and research gear Dragon will deliver are mice to be observed for the Rodent Research-6 muscle drug study. 20 mice will be housed in a rodent habitat that Vande Hei is configuring today in the U.S. Destiny laboratory.
Orbital ATK pushed back the release of its Cygnus resupply ship from the Unity module to Dec. 6 after the SpaceX announcement. Flight Engineers Joe Acaba and Mark Vande Hei are preparing for the departure this week loading Cygnus with trash and training for its robotic release.
Acaba and cosmonaut Alexander Misurkin were inside the Kibo laboratory module today testing a pair of tiny satellites better known as SPHERES (Synchronized Position Hold, Engage, Reorient, Experimental Satellites). The SPHERES can be pre-programmed on Earth using algorithms to conduct a series of maneuvers demonstrating formation flying or rendezvous and docking techniques. Teams of high school students will be competing in January to see who can design the best maneuvering algorithms for the SPHERES on the station.
The Cygnus resupply ship is in its final week at the International Space Station and two astronauts are training for its departure on Monday. Meanwhile, a leg muscle study and CubeSat deployment operations are wrapping up today.
The duo will be inside the cupola commanding the Canadarm2 to release Cygnus back into Earth orbit on Dec. 4. Following its departure from the station, Cygnus will stay in orbit until Dec. 18 before re-entering the Earth’s atmosphere for a fiery demise over the Pacific Ocean.
Commander Randy Bresnik and cosmonaut Sergey Ryazanskiy are completing a final run of the Sarcolab-3 experiment today. That research is observing how leg muscles adapt to microgravity using magnetic resonance imaging and ultrasound devices.
Finally, a satellite deployer that ejected a set of CubeSats last week, has been brought back inside the Kibo lab module. One of the CubeSats deployed, the EcAMSat that was delivered aboard Cygnus, is now orbiting Earth researching how the E. coli pathogen reacts to antibiotics in space.
