NASA Administrator Jim Bridenstine made his first official visit to the agency’s Kennedy Space Center on Aug. 6 and 7 for an up-close look at the premier, multi-user spaceport.
Bridenstine’s visit began with Center Director Bob Cabana giving the administrator a helicopter tour of the bustling Florida spaceport.
During an all hands meeting for Bridenstine to speak with employees, Cabana commented on the spaceport’s shift.
“The transition that you all have made in the last seven years since (space shuttle) Atlantis made its final fight has been nothing short of phenomenal,” he said. “I’ve had the privilege the past two days to share the work that you all have accomplished with our new NASA administrator, who is passionate about what we do.”
Bridenstine also thanked Kennedy employees for their part in the recent changes.
“You have transitioned splendidly,” Bridenstine said. “When you look at how Kennedy has handled the challenge and how you have turned this into a multi-user spaceport with commercial and other partners, I’m inspired and in awe.”
For nearly half a century, Kennedy operated as a NASA-only space center. As the Space Shuttle Program came to an end, Kennedy began preparing to support NASA’s Space Launch System (SLS) rocket and Orion spacecraft. Anticipation of an emerging commercial space industry resulted in center leadership developing an innovative concept of a multi-user spaceport to change focus from a big government, NASA-only space center to the agency partnering with other organizations.
The administrator also spoke of the crucial role NASA plays in everyday life around the globe.
“Space is important to our everyday lives,” he said. “Look at how space has transformed all of our lives. You look at the way we communicate, the way we navigate, the way we produce food, the way we produce energy, the way we do disaster relief in this country and the world, the way we provide national security and defense, every person in our country and every human on the planet has benefited from what NASA has done.”
In addition to touring Kennedy facilities, Bridenstine participated in an Industry Roundtable hosted by the Economic Development Commission of Florida’s Space Coast and Space Florida. He later met with members of the news media in the center’s Space Florida’s Space Life Sciences Lab facility.
As astronauts prepare for trips to destinations beyond low-Earth orbit, their last steps before boarding an Orion spacecraft will be across the Crew Access Arm (CAA) on the mobile launcher.
Earlier this year, the CAA was added to the mobile launcher being prepared to support NASA’s Orion spacecraft and Space Launch System (SLS) rocket, the largest in the world. Technicians and engineers in Exploration Ground Systems at the agency’s Kennedy Space Center recently tested the crucial arm, confirming it worked as designed.
The test was designed to determine the functionality and integrity of the CAA and supporting mobile launcher systems.
“This was the first functional swing testing for the Crew Access Arm,” said Cliff Lanham, Mobile Launcher Project Manager at Kennedy. “Prior to testing, we checked the mechanical attachment, hydraulics and cabling to make sure we had confidence it would work properly.”
The CAA is designed to rotate from its retracted position and line up with Orion’s crew hatch. The arm will provide entry and emergency egress for astronauts and technicians into and out of the Orion spacecraft.
In advance of those missions, the Exploration Ground Systems team at Kennedy has been overseeing testing of umbilicals and other launch accessories on the 380-foot-tall mobile launcher in preparation for stacking the first launch of the SLS rocket with Orion.
During the test, there were several moves of the arm controlled by systems on the mobile launcher. The test also was important because of the upcoming move of the mobile launcher from its park site to the Vehicle Assembly Building (VAB).
“The CAA will be extended when it goes inside the VAB,” Lanham said. “We cannot rotate the arm once in the VAB due to space constraints.”
Testing inside the VAB is designed to ensure all systems work properly in connection with the building prior to stacking the first SLS and Orion for Exploration Mission-1. EM-1 will be the first unpiloted flight of the new NASA spacecraft traveling 280,000 miles from Earth well beyond the Moon.
The team that tested the umbilical lines and launch accessories that will connect from the mobile launcher (ML) to NASA’s Space Launch System (SLS) rocket and Orion spacecraft for Exploration Mission-1 celebrated their achievement during a banner signing at the Launch Equipment Test Facility (LETF) at the agency’s Kennedy Space Center in Florida.
Engineers and technicians in the Engineering Directorate and the Exploration Ground Systems Program, along with contractor support, began the tests at the LETF about 2.5 years ago. The first to be tested was one of two aft skirt electrical umbilicals. Testing of the final umbilical, the second of two tail service mast umbilicals, was completed on June 27.
“The team of NASA test engineers and test managers, and contractor engineers and technicians, worked tirelessly six days a week, 10 hours a day, in order to meet the highly aggressive schedule and deliver the hardware to the mobile launcher for installation,” said Jeff Crisafulli, Test and Design branch chief in the Engineering Directorate.
In all, 21 umbilicals and launch accessories were tested on various simulators at the LETF that mimicked conditions during launch to ensure they are functioning properly and ready for installation on the ML. Most have been delivered and installed on the ML tower. These include the Orion service module umbilical, interim cryogenic propulsion stage umbilical, core stage forward skirt umbilical and core stage inter-tank umbilical. Two aft skirt electrical umbilicals, two aft skirt purge umbilicals, a vehicle stabilizer system, eight vehicle support posts and two tail service mast umbilicals were installed on the 0-level deck of the ML.
Before launch, the umbilical lines will provide power, communications, coolant and fuel to the rocket and spacecraft. Additional accessories will provide access and stabilization. During launch, each umbilical and accessory will release from its connection point, allowing the SLS and Orion to lift off safely from the launch pad.
“Design, fabrication and testing of the new mobile launcher’s umbilicals and launch accessories is a once-in-a-lifetime opportunity that I am proud to have been part of,” Crisafulli said.
NASA’s Kennedy Space Center celebrated National Intern Day on Thursday, July 26, by highlighting various interns around the center. Throughout the day, the interns posted photos and videos on their Instagram story as part of their intern social media takeover. NASA interns at every center watched the agency’s administrator, Jim Bridenstine, as he spoke with interns at Goddard Spaceflight Center in Greenbelt, Maryland.
The third and final aeroshell, at left, for Orion’s Launch Abort System (LAS) is in High Bay 4 of the Vehicle Assembly Building on July 12, 2018, at NASA’s Kennedy Space Center in Florida after its arrival from EMF Inc. on nearby Merritt Island. In the photo above, technicians prepare the aeroshell to be lifted off of the flatbed truck and transferred to slats. All three aeroshells will be stacked and prepared for a full-stress test of the LAS, called Ascent Abort-2 (AA-2) flight test, scheduled for April 2019.
During the test, a booster will launch from Space Launch Complex 46 at Cape Canaveral Air Force Station carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles per hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space.
