Boeing’s CST-100 Starliner propulsion system was put to the test on Thursday at NASA’s White Sands Test Facility in New Mexico in support of NASA’s Commercial Crew Program. Teams ran multiple tests on Starliner’s in-space maneuvering system and the spacecraft’s launch abort system, which are key elements on the path to restore America’s capability to fly astronauts to the International Space Station on American rockets and spacecraft from U.S. soil.
The test used a flight-like Starliner service module with a full propulsion system comprising of fuel and helium tanks, reaction control system and orbital maneuvering and attitude control thrusters, launch abort engines and all necessary fuel lines and avionics.
During the test:
19 thrusters fired to simulate in-space maneuvers.
12 thrusters fired to simulate a high-altitude abort.
22 propulsion elements, including the launch abort engines, fired to simulate a low-altitude abort.
Boeing’s Starliner will launch on a United Launch Alliance Atlas V rocket from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. The company will complete a Starliner pad abort test and uncrewed flight test, called Orbital Flight Test, to the station ahead of the first flight test with a crew onboard. As commercial crew providers, Boeing and SpaceX, begin to make regular flights to the space station, NASA will continue to advance its mission to go beyond low-Earth orbit and establish a human presence on the Moon with the ultimate goal of sending astronauts to Mars.
The United Launch Alliance Atlas V rocket that will launch Boeing’s CST-100 Starliner on the Crew Flight Test (CFT) mission to the International Space Station for NASA’s Commercial Crew Program emerged on Thursday from the production factory in Decatur, Alabama for transport in a giant cargo ship to Cape Canaveral Air Force Station in Florida.
The rocket, known as AV-082, will launch Starliner and its crew of NASA astronauts Mike Fincke and Nicole Mann, and Boeing astronaut Chris Ferguson to the station following the spacecraft’s maiden voyage, the uncrewed Orbital Flight Test targeted for August.
From the manufacturing facility in Decatur, Alabama, the Atlas V booster stage and Dual Engine Centaur upper stage were moved down the road for loading into the Mariner vessel docked nearby. The 312-foot-long ship is purpose-built to navigate both shallow waters of rivers and ocean travel to reach ULA’s launch sites. It has been making the trek from Decatur to Cape Canaveral since 2001.
Once at Cape Canaveral, the Atlas V will begin integrated operations and processing for the CFT launch.
NASA selected Boeing and SpaceX to transport crew to the space station from the United States, returning the nation’s human spaceflight launch capability. These integrated spacecraft, rockets and associated systems will carry up to four astronauts on NASA missions.
Regular commercial transportation using Boeing’s Starliner and SpaceX’s Crew Dragon spacecraft to and from the station will enable expanded station use and additional research time aboard the orbiting laboratory. Research on the space station helps address the challenges of moving humanity forward to the Moon and Mars as we learn how to keep astronauts healthy during long-duration space travel and demonstrate technologies for human and robotic exploration beyond low-Earth orbit.
Boeing and Aerojet Rocketdyne have begun a series of developmental hot-fires tests with two launch abort engines similar to the ones that will be part of Boeing’s Starliner service module. The engines, designed to maximize thrust build-up, while minimizing overshoot during start up, will be fired between half a second and 3 seconds each during the test campaign. If the Starliner’s four launch abort engines were used during an abort scenario, they would fire between 3 and 5.5 seconds, with enough thrust to get the spacecraft and its crew away from the rocket, before splashing down in the ocean under parachutes.
Recently, Aerojet Rocketdyne also completed delivery of the first set of hardware for Starliner’s service module propulsion system.
The Starliner is under development in collaboration with NASA’s Commercial Crew Program for crew missions to the International Space Station.
You can see Florida taking shape on the front of Boeing’s Commercial Crew and Cargo Processing Facility, better known as C3PF, at NASA’s Kennedy Space Center. The 78,000 foot facility will be the production and processing home of Boeing’s Crew Space Transportation (CST)-100 spacecraft.
What do you expect Boeing will add to the wrap next?
“Sometimes when you are an engineer, you have to get it wrong, before you can get it right,” said Rebecca Regan, an employee at NASA’s Kennedy Space Center.
Yesterday, Regan taught 17 elementary school students at Kennedy’s Child Development Center about the Commercial Crew Program and the need to have American-made spacecraft and rocket systems to carry people to and from space. After the lesson, each student built their own spacecraft out of cardboard boxes and art supplies.
Take a look at the designs these budding engineers created.
Want to build your own spacecraft this summer? We used the following supplies:
Disposable plates (for portholes)
Pictures (to place on the portholes)
Plastic cups (to make rocket engines)
Foil (to cover the cups)
Tissue Paper – red, orange and yellow (to make fire for the engines)
