<\/p>\nSpaceX and Boeing continue to make steady progress towards the major flight tests under NASA\u2019s Commercial Crew Program. At a NASA Advisory Council (NAC) meeting on Monday, the members were updated on the progress of each of the two providers. Overall, the updates were quite positive with most of the flight hardware nearing completion.<\/p>\n<\/p>\n
The two companies must each execute two test flights to the International Space Station (ISS) in order to be certified to perform operational crew rotation missions.<\/p>\n
On the SpaceX side, the company will first execute an uncrewed test flight of the Crew Dragon spacecraft called Demonstration Mission 1 (DM-1) \u2013 currently scheduled for this coming November. It will then be followed by a crewed test flight designated Demonstration Mission 2 (DM-2). In between the two missions, SpaceX will also execute an in-flight abort test.<\/p>\n
In terms of Boeing, they will perform an uncrewed Orbital Flight Test (OFT) with the CST-100 Starliner followed by a Crewed Flight Test (CFT). A pad abort test will be also conducted between the two missions.<\/p>\n

Following the crewed test flights, NASA will review the data before certifying the providers to perform the operational Post-Certification Missions (PCMs).<\/p>\n
There has been increasing schedule pressure for at least one of the providers to become certified in the near future, as NASA was scheduled to run out of seats on the Russian Soyuz capsule in the fall of 2019.<\/p>\n
However, Bill Gerstenmaier \u2013 NASA\u2019s associate administrator for the Human Exploration and Operations Directorate \u2013 announced that the margin has now been extended until January 2020. The extension was achieved by lengthening the duration of the upcoming Soyuz missions.<\/p>\n

Having a company test pilot is part of Boeing\u2019s traditional testing procedures. As Kathy Lueders \u2013 the Program Manager of NASA\u2019s Commercial Crew Program \u2013 stated, \u201cThey\u2019ve flown a Boeing test pilot on every vehicle that they\u2019ve ever flown.\u201d<\/p>\n Boeing test pilot Chris Ferguson works through a simulation training.

Doing so would ease the schedule pressure on the program.<\/p>\n Lueders explained, \u201cWe are working with Station and we will see the progress of where the crewed flight tests are and we have the flexibility to make that a longer duration mission if we need to have it be a longer duration mission.\u201d<\/p>\n<\/p>\n However, Boeing\u2019s test pilot, Christopher Ferguson, is not a current NASA astronaut. Instead, he is employed by Boeing. Therefore, there was an area of uncertainty as to how he would be able to execute a long-duration ISS mission without the Station training performed by NASA astronauts.<\/p>\n Lueders announced at the meeting that they \u201cadded a NASA crew member and then had the ability to have it be a long duration\u2026.\u201d Additionally, Ferguson has begun the required training.<\/p>\n When asked if the extra NASA astronaut would still fly if CFT remains short-duration, Lueders confirmed that the third person will fly no matter what.<\/p>\n NAC members expressed concerns with this proposition, as doing so increases human risk despite the extra crew member not being required. However, Lueders assured them that they had weighed the risks. Additionally, she stated that the \u201cflight operations director really liked to have two NASA crew members on there.\u201d <\/p>\n The Atlas V launch vehicles for Boeing\u2019s test flights are nearing completion.

It is expected to ship to the Cape aboard the Delta Mariner vessel this fall.<\/p>\n Additionally, \u201cSpacecraft #3 that is our Orbital Flight Test vehicle is going through Crew Module integration activities right now and the Service Module is in the final stage of outfitting,\u201d according to Lueders.<\/p>\n Spacecraft #1 which will execute the pad abort test and Spacecraft #2 which will perform the crewed flight test are also nearing completion. However, modifications may still have to be made. <\/p>\n During a hot fire test at White Sands Missile range, toxic propellant was spilled on the vehicle and the test stand after the engine valves failed to close.<\/p>\n Lueders stated, \u201cThey ended up finding out that they had some issues with some of the launch abort engine components. They are working through that right now and identifying what upgrades need to be made\u2026.That\u2019s why we test.\u201d<\/p>\n The investigation and corrective actions required is the largest concern in Boeing\u2019s schedule.<\/p>\n Boeing has numerous dress rehearsals coming up in the fall. Credit: NASA<\/p>\n However, in the meantime, the teams are making progress on other aspects of the program including the training between the different teams. After all, both the NASA and Boeing aspects will have to integrate seamlessly together on launch day.<\/p>\n Lueders explained, \u201cWe continue to do joint tests with Station. Obviously, you need to make sure that the vehicles are going to fit together.\u201d<\/p>\n Two joint docking simulations between NASA and Boeing have already been completed. Additionally, two Mission Dress Rehearsals (MDRs) and a Wet Dress Rehearsal (WDR) are coming up later this fall.<\/p>\n SpaceX:<\/b><\/p>\n This November, SpaceX is set to conduct DM-1 \u2013 the first orbital launch of the Commercial Crew Program.<\/p>\n In a sign of increasing optimism in the SpaceX schedule, Lueders showed a slide that stated that the DM-1 Crew Dragon spacecraft will be \u201claunch ready\u201d by the end of September.<\/p>\n SpaceX\u2019s DM-1 spacecraft will be \u201claunch ready\u201d by the end of September. Credit: NASA<\/p>\n The only key milestone left to be completed on the capsule front is the integration with the trunk. The trunk is currently undergoing solar array installation at SpaceX\u2019s Hawthorne California headquarters before shipment in the coming weeks.<\/p>\n Meanwhile, B1051.1 \u2013 the Falcon 9 first stage which will launch DM-1 \u2013 is currently at SpaceX\u2019s test facility in McGregor Texas where it is undergoing a rigorous testing campaign. Within the next few weeks, it will be transported to the Cape ahead of launch.<\/p>\n<\/p>\n That leaves only the second stage remaining. It is currently in Hawthorne and is expected to ship to McGregor for testing in the near future. From there, it will be sent to the Cape. If all goes to plan, it will also arrive in September.<\/p>\n Therefore, all the key hardware components for the DM-1 launch will be onsite more than a month before launch \u2013 a positive sign that the hardware will be ready in time.<\/p>\n Once the DM-1 mission occurs, SpaceX will have to quickly refurbish the DM-1 capsule. It is currently scheduled to fly again on the in-flight abort test. <\/p>\n Lueders explained, \u201cThey are able to do that because they right now are not planning to reuse their spacecraft [for regular missions]. Right now what they proposed is a new vehicle every time for us.\u201d<\/p>\n On the other hand, Boeing\u2019s plan calls for reuse of Starliner. Therefore, they are proving their in-flight abort capability via computer simulations, as they cannot afford to risk losing a spacecraft.<\/p>\n The Crew Dragon capsule for the DM-2 mission. Credit: Jack Beyer for NSF L2<\/p>\n As far as the DM-2 capsule which will fly two NASA crew members, it is also nearing completion and will be ready as soon as January.<\/p>\n With this in mind, the greatest concern in the SpaceX schedule is whether or not the Crew Dragon capsule can be turned around fast enough for the in-flight abort test. The test \u2013 currently scheduled for March \u2013 must be executed before DM-2 in April. Therefore, there is very little schedule margin.<\/p>\n Interestingly, it was also mentioned at the meeting that SpaceX and NASA are considering changing the DM-2 mission to a crew rotation flight similar to Boeing. If this change does occur, it will likely lead to a change with the DM-2 schedule, as timing would become heavily dependent on the ISS schedule.<\/p>\n Another area of significant importance on the SpaceX end is the qualification of Falcon 9\u2019s components. Lueders stated, \u201cThe turbine wheel testing has actually been completed, we are working through our MVac testing right now, and working through the upgraded COPV tests.\u201d<\/p>\n Finally, like with Boeing the SpaceX and NASA teams are performing regular training activities to finalize routines for launch and recovery activities.<\/p>\n LC-39A is nearly ready to support crewed spaceflight. Credit: NASA<\/p>\n According to a presentation slide, SpaceX recently completed a \u201csuccessful dry run of Day of Launch Closeout Crew procedures with representative crew members, space suits, and Model X\u2019s.\u201d<\/p>\n This statement seems to indicate that the Tesla Model X will serve as SpaceX\u2019s equivalent to the NASA astronaut transfer van by driving the astronauts to the pad.<\/p>\n On the test itself, Lueders added, \u201cGetting the crew timeline was very important for us. We got crew members in suit, took them out, went through the whole timeline of loading and working through making sure we really understood what was required to take the crew out to the pad.<\/p>\n \u201cThe crew access arm is now up. They are actually doing testing on the arm right now. We are getting ready for our final Launch Site Operational Readiness Review. We were really waiting for the arm to go out so we could do the final closeout testing out at the pad for crew capabilities.\u201d<\/p>\n That final review is currently scheduled for September.<\/p>\n","protected":false},"excerpt":{"rendered":" SpaceX and Boeing continue to make steady progress towards the major flight tests under NASA\u2019s Commercial Crew Program.
