Ken Kremer -- SpaceUpClose.com & RocketSTEM – 10 May 2019

PORT CANAVERAL, FL- Three days after sailing vertically into Port Canaveral on the OCISLY droneship the landed SpaceX Falcon 9 1st stage booster used to launch the Dragon CRS-17 cargo freighter to the International Space Station (ISS) in the middle of the night May 4, became the first one ever to be transported horizontally back to Cape Canaveral with all four of its landing legs fully retracted and intact, Wednesday afternoon May 8.

With this feat, SpaceX achieved a significant milestone towards cutting the turnaround time for rocket recycling to another blastoff long sought by SpaceX billionaire CEO and founder Elon Musk.

Enjoy our belated Space UpClose gallery of imagery documenting all the thrilling action from onsite at Port Canaveral as we were busy witnessing all the exciting action this past week – starting with the launch and landing, return to Port, craning off OCISLY and  the first ever fully successful landing leg retraction operation and transport back to Cape Canaveral Air Force Station.

Check back as the gallery grows.

Thus the day when SpaceX can actually achieve a 24 hour landing-to-launch turnaround is still a ways off in the future. However, this mission represents clear progress towards Musk’s goal of rapid reusability. 

“One of the biggest reusability improvements was fast leg stow. Version 1 sometimes took days,” Musk tweeted during the process.

Upon the successful introduction of the significantly upgraded Block 5 version of the Falcon 9 exactly 1 year ago in May 2019 SpaceX CEO Musk said the landing legs would all be retracted as one of the key requirements toward achieving rapid rocket turnaround for recycled booster launches. 

So it was surprising when that tuned out not to be the case for the first few recovered Block 5 boosters last year.

Overall it took the SpaceX team nearly 4.5 hours to raise the 4 legs and keep them stowed against the core stage on May 7 – starting around 2 p.m. EDT and concluding at nearly 6:30 p.m.

Using two cranes the booster with the fully retracted landing legs was carefully lowered horizontally onto the multi-wheeled transporter Wednesday morning May 8.

The team then basically clamped the booster firmly down onto the transporter by attaching the remaining ring segments front and back. 

The crane workers also detached the hi tech hoisting device we informally name the BLLRD – or Booster Lift and Leg Retraction Device rom the top/front and placed in holding cradle.

By 1 p.m. all that preparatory work was completed and the team fired up the transporter and drove it away from the Port Canaveral berthing site and moved it without much pause completely through the gates at the Air Force Station.

Soon SpaceX engineers will inspect the booster and refurbish it for its next mission. 

NASA and SpaceX managers say that this recovered booster could potentially be recycled to the next cargo mission to the ISS for the CRS-18 launch as soon as this summer. 

The SpaceX Falcon 9 successfully blasted off at 2:48 a.m. EDT (0648 GMT) Friday, May 4 with the unpiloted Dragon CRS-17 cargo ship from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida bound for the ISS with almost 3 tons of science investigations and supplies and included research into Earth’s carbon cycle, numerous biomedical and physical sciences investigations and the formation of asteroids and comets.

The Dragon CRS-17 resupply arrived safely two days later early Monday morning, May 6 loaded with approximately 5,500 pounds of NASA cargo and science investigations

The CRS-17 booster model B1046 had safely touched down on OCISLY some eight minutes after launch May 4 at a spot located just a few miles offshore of the Florida Space Coast beaches for the first time ever.  

The two stage Falcon 9/Dragon rocket stands about 213-feet (65-meters) tall.

The next SpaceX Falcon 9 launch is tentatively targeted for May 15 at 10:30 p.m. EDT.
