United Launch Alliance’s Atlas V Rocket
The Atlas V rocket, a longstanding fixture in space mission launches, is on the cusp of a significant milestone: transitioning from unmanned missions to manned spaceflights. For over two decades, the United Launch Alliance’s Atlas V rocket has been instrumental in carrying out pivotal missions, such as the Mars Reconnaissance Orbiter and the OSIRIS-REx sample return expedition to asteroid Bennu.
Today, however, marks a groundbreaking juncture for the Atlas V rocket, as it embarks on a mission to ferry two NASA astronauts aboard Boeing Starliner. This venture, aptly named the Crew Flight Test (CFT), will see NASA astronauts Butch Wilmore and Suni Williams journeying to the International Space Station (ISS) at 10:34 p.m. (0234 GMT on Tuesday, May 7).
Preparation and Readiness
Preparing the Atlas V rocket for crewed missions has been a meticulous and arduous process. Ian Kappes, the deputy manager for the launch vehicle system within NASA’s Commercial Crew program, shed light on the rigorous assessments and verifications undertaken by the team to ensure the rocket’s readiness. With over 11,000 to 12,000 verifications scrutinized, the team diligently combed through data and evaluations to ascertain the rocket’s operational precision.
Kappes, a veteran within the commercial crew program since 2014, emphasized the exhaustive process of examining both new and historical data to validate the vehicle’s human rating. The meticulous scrutiny extended to various technical facets, including the abort system, vehicle accelerations, avionics, and more.
Stringent Compliance with Safety Standards
While United Launch Alliance boasts a flawless track record with the Atlas V rocket since its inaugural launch in 2002, Kappes stressed the team’s unwavering commitment to upholding stringent safety protocols. Guarding against complacency, the team meticulously adhered to NASA’s stringent human spaceflight requirements, ensuring that every aspect of the ascent phase aligned with safety imperatives.
Kim Ess, the manager of the integrated performance office in NASA’s Commercial Crew program, reiterated the paramount importance of precision in the ascent trajectory to safeguard crew, public, and station integrity. Discussions spanned critical elements such as guidance, navigation, flight mechanics, spacecraft loads, staging precision, and emergency abort protocols.
Infrastructure Development and Safety Integration
Noteworthy in this mission’s preparations was the meticulous review and alignment of safety requirements between NASA and the Space Force. Crystal Jones, overseeing the commercial crew program’s ground and mission operations office, highlighted the intricate process of ensuring seamless compliance with safety mandates from both entities.
Among the infrastructure advancements, the crew access tower underwent rigorous scrutiny to meet the exacting standards necessary for space missions. Collaboration between NASA, the commercial crew program, and the Space Force ensured that safety imperatives were not just met but harmonized to facilitate a successful launch.
Anticipation and Confidence
With the launch looming on the horizon, a sense of anticipation and confidence pervades the team. Crystal Jones expressed a blend of surrealism and readiness as the culmination of tireless efforts and meticulous preparations near fruition. The team’s unwavering determination and meticulous attention to detail have instilled a sense of confidence in the mission’s success.
Reflecting on the collective journey towards this imminent milestone, Jones acknowledged a slight unease stemming from the proximity to launch, yet underscored its positive impact in fortifying the team’s resolve and preparedness. The culmination of dedication, expertise, and rigorous adherence to safety standards has primed the team for a successful mission.
