PORT CANAVERAL/CAPE CANAVERAL AIR FORCE STATION, FL – It was a evenly mixed bag of results for the SpaceX crane crews working on the landing legs of the 4 time recycled SpaceX Falcon 9 first stage booster from the Starlink 2 mission, as they were only able to successfully retract two while the other two were completely detached – perfect symmetry from opposite sides no less.
In other words the final outcome for the landing legs of the 156 foot tall 1st stage was perfectly balanced and evenly split at – 2 Up and 2 Off!
This Starlink 2 booster leg work began on Sat. Jan. 11 a day after it was craned off the “Of Course I Still Love You” (OCISLY) droneship mid-afternoon Friday, Jan. 10. And 2 days after it was towed back into Port Canaveral on Jan. 9 atop OCISLY.
The leg retraction work started successfully on Jan. 11 as 2 legs were retracted and continued unsuccessfully on Sunday, Jan. 12 as the crane crews attempted to use the hoisting cap to raise the legs flush against the side of the 156 foot tall story tall booster core.
From my perspective at Port Canaveral directly across from the ground pedestal the two side legs were raised successfully and the two front and back legs were not.
Instead they were dissected off in 2 steps separately – namely the landing leg struts and the landing leg pads.
And for what I think may well be the first time, the unique used Falcon 9 booster was lowered horizontal in the proportional 2 by 2 format for the first time around 230 PM EST Jan. 12 – and rolled back to the Cape looking black and white at the base.
Enjoy our Space UpClose photo gallery of the 2 by 2 Falcon 9 booster 1049.4 standing both vertical and resting horizonal taken over this weekend of the SpaceX crane crew efforts on Saturday and Sunday Jan. 11 and 12 at Port Canaveral.
Before the landing leg retraction work started on Saturday I observed the workers quite thoroughly hosing down the recycled boosters 4 landing legs on Friday.
The booster was transported horizontally back to the Cape on Monday, Jan 13 on the white wheeled transporter for eventual reuse.
One by one they methodically shot a fire hefty stream of water to wash each strut and landing pad for several minutes each – gradually circling around to all four legs – with the booster still standing upright on the OCISLY droneship.
Thus the workers apparent attempt at rinsing the leg mechanisms of accumulated sprays of sea salt, chemicals contaminants, greases, oils and assorted FOD and more was only partially successful.
Presumably SpaceX tried the landing leg cleansings to help enable the difficult leg retractions work as the strut piston segments are closed in.
During the leg retraction work I have often seen the workers halt in fits and starts to inspect the strut pistons and wipe them clean.
Sometimes the wiping works and the leg is fully retracted- and other times the retraction fails for an unknown host of reasons.
The bottom line is SpaceX still has many lessons to learn and new experiments and procedures to try in order to make the leg retractions more robust – which clearly they are not at this time since only 2 legs were retracted.
Booster 1049.4 arrived into Port Canaveral Thursday late afternoon Jan. 9 barely three days after the thrilling first blastoff of 2020 streaked to orbit Monday night Jan. 6 from the Florida Space Coast on only the second quadruply launched SpaceX Falcon 9 booster.
It launched on the 3rd Starlink mission carrying 60 broadband internet satellites.
The quadruply recovered 1st stage booster sailed into Port Canaveral atop the OCISLY droneship Thursday during a rare late afternoon arrival Jan. 9 under picture perfect sunlight accompanied by crashing waves for an exciting arrival into Jetty Park Pier and Port Canaveral, Florida.

The craning off OCISLY away from the clutches of the octograbber and onto the regular land pedestal started at about 3 p.m. EST took about 30 minutes – overall about the same length of time as with the old yellow crane prior to the Liebherr.
Liftoff of the 3rd Starlink mission – officially designated as Starlink 2 – on this fourth time recycled Falcon 9 took place during an instantaneous launch window at 9:19 p.m. EST Monday, Jan. 6 (0219 GMT Tuesday, Jan. 7) from Space Launch Complex-40 (SLC-40) on Cape Canaveral Air Force Station, FL.
SpaceX then successfully soft landed the Falcon 9 first stage for the fourth time – in this case on the “Of Course I Still Love You” (OCISLY) droneship deployed some 400 miles (620 km) downrange in the Atlantic Ocean off the Carolinas coast.
In another major milestone in rocket recycling the mission marks only the second time use of a reused first stage booster for the fourth time.
The first 4th flown booster was used on the prior Stalink mission launched on November 11, 2019.
This counts as the 48th successful booster landing recovery by sea or by land.
Thus the booster is set up to launch for a record fifth time perhaps later this year.
To date it flew on three prior missions on Starlink 1 in May 2019 as well as Iridium-8 and the Telstar 18 VANTAGE mission.
The Block 5 Falcon 9 first stages are designed to launch 10 times each with minimal refurbishment between flights.
The two stage Falcon 9 rocket stands 229 feet (70 meters) tall.
SpaceX currently plans at least two additional Falcon 9 launches in January – almost back to back on Jan 18 and Jan 20.
Namely the InFlight Abort Test (IFA) Jan 18 to demonstrate the emergency abort escape capability with a Crew Dragon for NASA involving the ability to save the astronauts from a failing rocket in flight – and another Starlink mission now NET Jan 20.
