CAPE CANAVERAL AIR FORCE STATION, FL — The pancaked

leftovers of a SpaceX Falcon 9 first stage from last week's successful commercial launch

but hard landing at sea, pulled silently and without fanfare into its home port over the weekend - thereby ending

a string of three straight spectacular

and u

pright soft ocean landings

over the past two months.

The residue

of the Falcon

sailed into home port at Port Canaveral, Fl under cover of darkness and covered by a big blue tarp late Saturday night, June 18, at around 9 p.m. EDT.

It arrived atop SpaceX's ASDS drone ship landing platform known as "Of Course I Still Love You" or "OCISLY" - that had already been dispatched several days prior to the June 15 morning launch from the Florida space coast.

And check out this exquisite hi res aerial video of the tarp 'Blowing in the Wind' - showing an even more revealing view of the remains of the Falcon 9 after much of the tarp was blown away by whipping sunshine state winds.

Recovering and eventually reusing the 156 foot tall Falcon 9 first stage to loft new payloads for new paying customers lies at the heart of the visionary SpaceX CEO Elon Musk's strategy of radically slashing future launch costs and enabling a space faring civilization.

The latest

attempt to launch

and propulsively land the Falcon booster on a platform a sea

took place on Wednesday, June 15

after the on time liftoff at 10:29 a.m. EDT (2:29 UTC) from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.

The 229 foot-tall (70 meter) Falcon 9 successfully accomplished its primary goal of delivering a pair of roughly 5000 pound commercial telecommunications satellites to a Geostationary Transfer Orbit (GTO) for Eutelsat based in Paris and Asia Broadcast Satellite of Bermuda and Hong Kong.

The Falcon 9 delivered the Boeing-built EUTELSAT 117 West B and ABS-2A telecommunications satellites to orbits for Latin American and Asian customers.

"Ascent phase & satellites look good," SpaceX CEO and founder Elon Musk tweeted.

After first stage separation, SpaceX engineers attempted the secondary and experimental goal of soft landing the 15 story tall first stage booster nine minutes after liftoff, on an ocean going 'droneship' platform for later reuse.

OCISLY was stationed approximately 420 miles (680 kilometers) off shore and east of Cape Canaveral, Florida in the Atlantic Ocean.

However, for the first time in four tries SpaceX was not successful in safely landing and recovering the booster intact and upright.

The booster basically crashed on the drone ship because it descended too quickly due to insufficient thrust from the descent engines.

The rocket apparently ran out of fuel in the final moments before droneship touchdown.

"Looks like early liquid oxygen depletion caused engine shutdown just above the deck," Musk explained via a twitter post.

The first stage is fueled by liquid oxygen and RP-1 propellant.

A SpaceX video shows a huge cloud of black smoke enveloping the booster in the final moments before the planned touchdown - perhaps soot from the burning RP-1 propellant.

In the final moments the booster is seen tipping over and crashing with unrestrained force onto the droneship deck - crushing and flattening the boosters long round core and probably the nine Merlin 1D first stage engines as well.

"But booster rocket had a RUD on droneship," Musk noted. RUD stands for rapid unscheduled disassembly which usually means it was destroyed on impact. Although in this case it may be more a case of being crushed by the fall instead of a fuel related explosion.

"Looks like thrust was low on 1 of 3 landing engines. High g landings v sensitive to all engines operating at max," Musk elaborated.

The June 15 crash follows three straight landing successes at sea - on April 8,

May 6

and

mostly recently on May 27

after

the Thaicom-8 launch

. See

my onsite coverage

here of

the Thaicom-8

boosters return to Port Canaveral on the OCISLY droneship.

Yet this outcome was also not unexpected due to the high energy of the rocket required to deliver the primary payload to the GTO orbit.

"As mentioned at the beginning of the year, I'm expecting ~70% success rate on landings for the year," Musk explains.

And keep in mind that the rocket recovery and recycling effort is truly a science experiment on a grand scale financed by SpaceX - and its aiming for huge dividends down the road.

"2016 is the year of experimentation."

It's a road that Musk hopes will one day lead to a human "City on Mars."
