Testing of several of the umbilical lines that will attach to NASA’s Space Launch System (SLS) rocket from the tower on the mobile launcher continues at the Launch Equipment Test Facility (LETF) at Kennedy Space Center in Florida.
The Core Stage Inter-tank Umbilical (CSITU) arrived at the LETF and was attached to the “C” tower of the Vehicle Motion Simulator 2 test fixture. Engineers with the Ground Systems Development and Operations Program and the Engineering Directorate will prepare the umbilical for a series of tests to confirm it is functioning properly and ready to support the SLS rocket for launch.
The tests will begin in January 2017 and are scheduled to be completed by the end of February. Testing will include hydraulic system controller tuning, umbilical plate mate and leak checks, primary and secondary disconnect testing at ambient temperatures, and fire suppression system functional checks. Also, a series of primary and secondary disconnect testing at liquid nitrogen and liquid hydrogen temperatures, minus 321 and minus 421 degrees Fahrenheit, respectively, will be performed.
The CSITU is a swing arm umbilical that will connect to the SLS core stage inter-tank. The umbilical’s main function is to vent gaseous hydrogen from the core stage. The arm also provides conditioned air, pressurized gases, and power and data connection to the core stage.
The CSITU will be located at about the 140-foot-level on the mobile launcher tower, between the Core Stage liquid hydrogen and liquid oxygen tanks, and will swing away before launch. The umbilical is one of several umbilicals that will be installed on the mobile launcher tower and attach to the SLS rocket and Orion spacecraft.
The Orion spacecraft is scheduled to launch in late 2018 atop the SLS rocket on a three-week mission that will take it thousands of miles beyond the moon and back during Exploration Mission 1.
More than five years of careful thought, in-depth planning and detailed refurbishments have set up Kennedy Space Center for diverse exploration missions that will push astronauts and robotic spacecraft into new areas of accomplishment, said, NASA’s Kennedy Space Center director, Bob Cabana at the National Space Club Florida Committee meeting today in Cape Canaveral.
“We’re not just making a difference for Kennedy or even the nation, we’ve got a meaningful mission and we are making a difference for all of humankind,” Cabana, a former astronaut, told the group of about 375 in attendance.
By focusing on piloted missions to the International Space Station using Commercial Crew Program spacecraft, followed by Space Launch System and Orion flight tests, Kennedy has established a ground support network of launch pads and associated infrastructure needed to support missions to Mars by astronauts in the future. All of this while maintaining the center’s unique ability to launch historic robotic exploration missions such as Osiris-Rex that will bring back a sample from an asteroid. Other flights in the future will continue to decipher the mysteries of Mars as well as taking close looks at other planetary networks in the solar system.
The center has seen complete upgrades in many areas including the Launch Control Center, Launch Complex 39B and modifications to the Mobile Launcher tailored to the needs of the SLS rocket and Orion spacecraft. Other facilities have been upgraded for commercial partners. The center’s new headquarters campus is under construction to deliver an environmentally friendly, energy efficient structure.
“Our future is absolutely outstanding,” Cabana said. “I believe the years we have ahead of us will be our best ever.”
Two pathfinders, or test versions, of solid rocket booster segments for NASA’s Space Launch System (SLS) rocket arrived at the agency’s Kennedy Space Center in Florida. The booster segments were transported from Promontory, Utah, for pathfinder operations at the Rotation, Processing and Surge Facility (RPSF) to prepare for Exploration Mission-1.
The boosters, which are inert, were stored at the Jay Jay rail yard in Titusville, Florida, to prepare for the final move. The first booster was transported onto the center Feb. 23 by rail aboard a train service provided by Goodloe Transportation and was delivered to the RPSF. Inside the RPSF, the booster segment was offloaded and inspected. Its cover was removed, and the segment will undergo additional inspections to confirm it is ready for testing. The second booster segment which arrived later in the day will undergo the same preparations.
During the pathfinder operations, engineers and technicians with NASA and industry partners will conduct a series of lifts, moves and stacking operations using the booster segments and an aft skirt, with aft motor and aft exit cone attached, to simulate how the boosters will be processed in the RPSF to prepare for an SLS/Orion mission. The stacking operations will help train ground personnel before they handle flight hardware for the most powerful rocket in the world that will start to arrive at Kennedy in less than two years.
The pathfinder operations also will help to test recent upgrades to the RPSF facility as the center continues to prepare for the EM-1 mission, deep-space missions, and the journey to Mars.
The Orion crew module pressure vessel for NASA’s Exploration Mission-1 (EM-1) has been secured in an upgraded version of a test stand called the birdcage in the high bay inside the Neil Armstrong Operations and Checkout (O&C) Building at the agency’s Kennedy Space Center in Florida.
The pressure vessel is the underlying structure of the Orion crew module. It arrived at Kennedy on Feb. 1 aboard NASA’s Super Guppy aircraft at the Shuttle Landing Facility operated by Space Florida at Kennedy. It was offloaded and transported to the O&C.
In the high bay, NASA and Orion manufacturer Lockheed Martin will prepare the vehicle for its mission. Over the next 18 months, more than 100,000 components will arrive at Kennedy and be integrated with the spacecraft by the team. It will be outfitted with its systems and subsystems necessary for flight, including its heat-shielding thermal protection system.
The Orion spacecraft will launch aboard NASA’s Space Launch System rocket on EM-1, a test flight that will take it thousands of miles beyond the moon over the course of about a three-week mission.
The Orion crew module pressure vessel for NASA’s Exploration Mission-1 (EM-1) arrived today at the Shuttle Landing Facility operated by Space Florida at NASA’s Kennedy Space Center in Florida. Arrival of the module marks an important milestone toward the agency’s journey to Mars.
The crew module arrived aboard the agency’s Super Guppy aircraft from NASA’s Michoud Assembly Facility in New Orleans. Welding work on the pressure vessel, which is the underlying structure of the crew module, was completed at Michoud.
The crew module was offloaded from the Super Guppy and readied for transport to the Neil Armstrong Operations and Checkout Building high bay for processing. In the high bay, NASA and Orion manufacturer Lockheed Martin will outfit the crew module with its systems and subsystems necessary for flight, including its heat-shielding thermal protection system.
NASA’s Space Launch System rocket will be the largest rocket ever built. It will carry the Orion spacecraft on EM-1, a test flight scheduled for 2018. During EM-1, Orion will travel thousands of miles beyond the moon over the course of a three-week mission.
Charlie Blackwell-Thompson will be the first woman to oversee a NASA liftoff and launch team when the EM-1 mission launches in 2018 to send an uncrewed Orion spacecraft around the moon on the strength of the Space Launch System rocket.
