Following a successful Falcon 9 launch-and-barge-landing in California this month, SpaceX is now looking to get back in the swing of regular flight. But while the companys next two flights seem fairly routine on the surface, theyre going to be historic in one very important aspect.
Two upcoming SpaceX launchesa commercial satellite on January 30th, and a commercial resupply mission to the International Space Station in Februarywill depart from the historic Launch Complex 39A (LC-39A) at Kennedy Space Center. It marks the first use of the pad that sent humans to the Moon since the Space Shuttle era, and the first rockets to fly from Kennedy, period, in over five years. Since the Shuttle program was mothballed in 2011, all rockets launches off Space Coast have flown from the adjacent Cape Canaveral Air Force Station.
This is important for Kennedy, space historian Roger Launius, the former associate director for the Smithsonian Air and Space Museum, told Gizmodo. [Kennedy] has been spaceport USA throughout the space age, more than 60 years now. The fact that youve got a company [putting] money into rehabbing an existing facility means youve got work for the foreseeable future.
Built in the 1960s as part of President Kennedys Moonshot program, LC-39A is legendary among rocket buffs. It was the site of 12 Saturn V rocket launches during the Apollo era, including the Apollo 11 mission which sent Neil Armstrong, Buzz Aldrin, and Michael Collins to the Moon. After the Apollo program, LC-39A became the de facto launch pad for the Space Shuttle era. A full 80 Shuttle missions departing the Earth from this single piece of beachfront real estate between the early 1980s and the summer of 2011.
Combining the history of 39A with SpaceX is a perfect storm of joy for rocket fans.When the Shuttle program was finally shuttered, LC-39A and Kennedy Space Center at large grew quiet for a few years. But in 2014, NASA granted SpaceX a 20-year exclusive lease to the pad, under an agreement that the rocket company would take over pad operation and maintenance costs. Since then, SpaceX has been busy refurbishing LC-39A for the Falcon 9 rocket and the larger, not-yet-revealed Falcon Heavy model.

But when a Falcon 9 rocket exploded just down the road last September, destroying a chunk of Cape Canaverals Space Launch Complex 40, plans to re-open Kennedy for spaceflights both crewed and uncrewed were accelerated.
Both pads are capable of supporting Falcon 9 and Falcon Heavy launches, SpaceX told SpaceNews.com last September, speaking of LC-39A and the companys launch site at Vandenberg Air Force Base in California. We are confident the two launch pads can support our return to flight and fulfill our upcoming manifest needs.
There are some key differences between how LC-39A was used in the past and how it will be used in 2017. Previously, the Shuttle was mated to its rocket boosters and external fuel tanks at the Vehicle Assembly Building a few miles away; it was then rolled down the road aboard a Crawler Transporter and loaded onto the launchpad. Now, SpaceX rockets will be processed at a new Horizontal Processing Facility constructed adjacent to 39A. The pad itself has been physically modified to accommodate Falcon 9 and Falcon Heavy rockets, although SpaceX declined to comment on the technical details of the renovations.

This is an order of magnitude more sophisticated than that analogy, but nonetheless, its the same sort of thing.
Are space buffs worried that LC-39A, a priceless legacy of the Moonshot era, will lose some of its historic character as it gets upgraded to accommodate modern rockets? Not exactly. According to Chris Bergin, managing editor for NASASpaceflight, the revival of a LC-39A is being greeted with unadulterated glee by most folks in the spaceflight community.
Seeing a famous old pad come back to life will be a huge positive for those who feel were now over the post-Shuttle retirement hill and looking to the future again, he told Gizmodo. Also, its SpaceX, they arewithout questionthe rock stars of space flight these days. Combining the history of 39A with SpaceX is a perfect storm of joy for rocket fans.
