NASA has confirmed Feb. 27th launch readiness overview (LRR) previous to the orbital debut of SpaceX’s Crew Dragon spacecraft concluded with all events remaining “go” for the historic launch.
Scheduled to liftoff at 2:48 am EST (07:48 UTC) on March 2nd, Falcon 9 and Crew Dragon can now start to roll out to Launch Complicated 39A (‘Pad 39A’) and full ultimate preflight checks roughly 24-48 hours earlier than launch. After relentless work over the previous few months, SpaceX has additionally largely accomplished a big collection of modifications – many aesthetic – to Pad 39A, giving the historic complicated a modern new black and white paint scheme and enclosed tower (FSS).
And there is the affirmation the LRR was accomplished and with a GO. Rollout is subsequent. Anticipate a number of cool pictures particularly with the 39A FSS now totally “cladded” in comparison with the picture within the tweet throughout the Static Hearth check. https://t.co/SQHcd3Ahgo

Falcon 9, Crew Dragon “go” for launch
Following up the Flight Readiness Assessment (FRR) 5 days later, the completion of the Launch Readiness Assessment (LRR) successfully signifies that SpaceX can now proceed into launch operations a bit like every other mission, rolling the rocket and spacecraft out to Pad 39A, taking the meeting vertical, and eventually finishing (comparatively) routine preflight preparations. SpaceX pad engineers and technicians have already accomplished a moist costume rehearsal (WDR) and static hearth check during the last two months, that means that they’ve already gained a big quantity of real-world expertise working with and working the model new Crew Dragon spacecraft and its human-rated Falcon 9 rocket.
This milestone has been the higher a part of a decade within the making, starting in 2009 or 2010 (relying on definitions) with funding from NASA devoted to what would finally turn into the Industrial Crew Program (CCP). SpaceX didn’t start to obtain rewards or devoted Crew Dragon-related funding till April 2011, when NASA awarded the corporate $75M to develop the spacecraft’s proposed integral abort system, counting on a newly developed Tremendous Draco engine. In August 2012, NASA awarded Sierra Nevada, SpaceX, and Boeing a number of hundred million every to proceed critical growth of their respective crewed spacecraft and launch autos, adopted in 2014 by agency long-term contracts with SpaceX and Boeing to carry their Crew Dragon and Starliner autos to fruition.
Of observe, SpaceX’s contract was valued at $2.6B, whereas Boeing acquired $four.2B, a full 60% extra to finish an successfully equivalent process. Sadly, the US Congress systematically underfunded CCP throughout its early life, largely a consequence of entrenched political and monetary pursuits in preferentially funding NASA’s personal SLS rocket and crewed Orion spacecraft above and at the price of different rocket and spacecraft growth initiatives. Inadequate funding probably contributed closely to the years of delays subsequently suffered by this system and its business suppliers, pushing a nominal launch debut goal from 2015 to 2017 earlier than finally shifting to 2018 and eventually 2019, largely a consequence of unsurprising technical challenges confronted by every supplier as they entered into hardware- and testing-rich phases of growth.
After roughly 5-6 years of concerted work, SpaceX and NASA at the moment are as prepared as they’ll ever be to conduct the primary orbital launch of the Industrial Crew Program, to be adopted as early as by Boeing’s personal uncrewed orbital demonstration of its Starliner spacecraft. For people who have adopted CCP for even a part of its years-long saga, it’s greater than slightly surreal to be confronted with the fact that such a milestone is barely two days distant.
Pad 39A: greater than only a contemporary coat
In the meantime, SpaceX’s leased Pad 39A launch complicated has undergone its personal important modifications. Courting again to NASA’s Apollo Program, Pad 39A supported all however one in every of Saturn V’s 13 launches and greater than 80 House Shuttle launches earlier than SpaceX took over the pad in 2014. Within the 5 years the corporate has leased the power, a variety of modifications have been made to the pad’s , help services, and the first metalwork often known as service constructions, one mounted (FSS) and one rolling (RSS). Except for a naked skeleton of the RSS hinge, SpaceX has fully eliminated a number of hundred tons of Shuttle help , whereas the FSS (the skyscraper-like rectangular tower) has remained largely unchanged, apart from the set up of a brand new stage and Crew Dragon’s Crew Entry Arm (CAA) on the ~110m (350 ft) tower.
Most not too long ago, the corporate has pursued a collection of visually distinct modifications to tower, portray it nearly completely black with white highlights and putting in partially clear black plexiglass panels alongside the complete size of not less than 2-Three of its 4 partitions. Whereas the paint coloration is nearly definitely aesthetically motivated (it matches Falcon 9, Crew Dragon, and the entry arm), the choice to surround all or a lot of the FSS will probably be very nicely acquired the astronauts and technicians it’s going to finally help, particularly if SpaceX manages to maintain out Florida’s infamous mosquitoes.
If SpaceX’s uncrewed DM-1 Crew Dragon demonstration is a hit, the corporate might observe it up with Crew Dragon’s first launch with astronauts aboard as early as July 2019, formally returning 39A to energetic place in human spaceflight and marking the tip of greater than eight years spent and not using a home answer for transporting US astronauts into orbit.
