SpaceX’s crewed Dragon launch debut likely to slip into 2020 as NASA pursues “realistic” dates
ByJamie Groh Posted on August 3, 2019
In a recent blog post, NASA made it clear that changes happening to leadership within the agency – specifically within the Human Exploration and Operations Directorate – are impacting the timelines to return astronauts to the International Space Station(ISS) from US soil. Agency conflicts are just the latest of several setbacks that have impacted the schedule of SpaceX’s crewed Crew Dragon launch debut.
Initially, the SpaceX Demo-2 mission set to carry NASA astronauts Bob Behnken and Doug Hurley to the ISS was slated to occur in the summer of 2019. That demonstration flight has since dropped off of the NASA launches and landings schedule, at least through October. SpaceX is now targeting a Demo-2 launch no earlier than December 2019 but an array of critical milestones must be completed to achieve that goal and both SpaceX and NASA have been keen to express that a crewed Crew Dragon launch in 2019 is a huge stretch.
According to the recent blog post, “NASA Administrator (Jim Bridenstine) has directed all programs in the Human Exploration and Operations Directorate to reexamine flight dates once new leadership is in place to deliver realistic schedule plans.” It is very likely that these new schedule plans will push the Demo-2 launch target into 2020.
Another roadblock that affects the timeline is the fact that SpaceX has yet to conduct an in-flight abort (IFA) test of the Crew Dragon capsule, meant to demonstrate the ability of the capsule’s SuperDraco thruster abort system to safely return crewmembers back to Earth in the event of an in-flight failure. SpaceX’s IFA has been delayed by multiple months after a catastrophic anomaly during an attempted April 2019 static fire test of the abort system resulted in the complete loss of the Crew Dragon capsule (C201), originally assigned to support the IFA. Although the capsule was destroyed, valuable lessons were learned about the pressurization and propulsion systems of Crew Dragon, particular “the flammability of the check valve’s titanium internal components” according to a July 15th statement released by SpaceX.
