KENNEDY SPACE CENTER, FL – With Sunday’s successful Falcon 9 blastoff for Iridium Communications joining rocketry’s history books, Elon Musk’s SpaceX accomplished a double headed American space spectacular this weekend with 2 launches and 2 booster landings in 2 days from 2 coasts for 2 commercial customers – in a remarkably rapid turnaround feat that set a new record for minimum time between launches for SpaceX.
With Billions and Billions of dollars at stake and their reputation riding on the line, SpaceX came roaring back to life by dramatically executing a picture perfect Falcon 9 rocket launch this morning (Jan. 14) that successfully delivered a fleet of ten advanced Iridium NEXT voice and data relay satellites to orbit while simultaneously recovering the first stage on a ship at sea off the west coast of California.
The stakes could almost not be higher for SpaceX as the firm readies their twice failed Falcon 9 rocket for a blastoff resumption on Saturday morning, Jan. 14 carrying the vanguard of the commercial Iridium NEXT satellite fleet to orbit from their California rocket base.
In the face of unrelenting days of very poor weather and a range conflict with another very critical rocket launch, SpaceX is pushing back the return debut of their private Falcon 9 rocket carrying a revolutionary fleet of voice and data commercial communications relay satellites for Iridium to no earlier than next weekend, Jan 14.

The Federal Aviation Administration (FAA) today “accepted the investigation report” regarding the results of SpaceX’s investigation into the cause of the company’s catastrophic Sept. 1, 2016 launch pad explosion of a Falcon 9 rocket in Florida, and simultaneously “granted a license” for the ‘Return to Flight’ blastoff of the private rocket from California as soon as next week – the FAA confirmed today to Universe Today, Friday, Jan. 6.

After an intensive four month investigation into why a SpaceX Falcon 9 rocket exploded without warning on the launch pad last September, the company today announced the failures likely cause as well as plans of a rapid resumption of flights as soon as next Sunday, Jan. 8, from their California launch complex – carrying a lucrative commercial payload of 10 advanced mobile relay satellites to orbit for Iridium Communications.

Technicians have fueled, stacked and tucked the first ten advanced IridiumNEXT mobile voice and data relay satellites inside the nose cone of a Falcon 9 rocket designated as SpaceX’s ‘Return to Flight’ launcher – potentially as early as next week – from their west coast launch pad on Vandenberg Air Force Base in California.

SpaceX is postponing the resumption of launches for their Falcon 9 rocket into early January 2017 as they continue to deal with the fallout from the catastrophic launch pad explosion in Florida that destroyed a Falcon 9 during preflight test operations three months ago. The new space aerospace company led by billionaire CEO Elon Musk […]

Only three months after the catastrophic launch pad explosion of their commercial Falcon 9 rocket in Florida, SpaceX has set Dec. 16 as the date for the boosters ‘Return to Flight’ launch from California with the first batch of Iridium’s next-generation communications satellites.

SpaceX came much closer to sticking the landing of their Falcon 9 rocket on a tiny droneship at sea than initially thought, as evidenced by a dramatic video of the latest attempt to recover the booster by making a soft ocean touchdown on Sunday, Jan. 17, after successfully propelling a US-European ocean surveillance satellite to low Earth orbit.
As seen in a vivid new birds eye video view of the landings final moments released by SpaceX CEO and billionaire founder Elon Musk, the first stage booster indeed descended slowly towards the small barge in the Pacific Ocean right on target for pinpoint soft landing.
The rocket landed just 1.3 meters (4 feet) off center of the bullseye on the oceangoing barge.
Unfortunately it then tipped over due to a malfunctioning landing leg that failed to lock in place, possibly due to ice buildup, hit the droneship deck and quickly exploded into a raging fireball.
Musk published the spectacular landing footage on Instagram – see below – showing the rocket propelled descent, droneship landing, tipover and ultimate fiery destruction of the Falcon 9 first stage after returning from a payload delivery to the edge of space, some 10 minutes earlier.
“Falcon lands on droneship, but the lockout collet doesn’t latch on one the four legs, causing it to tip over post landing,” Musk wrote in a description.
The 156 foot tall Falcon 9 first stage is equipped with four landing legs and four grid fins to enable the propulsive landing atop the barge once the first stage separates and relights a Merlin 1D engine.
“Root cause may have been ice buildup due to condensation from heavy fog at liftoff.”
Falcon 9 successfully launched the NASA/NOAA/European Jason-3 sea level rise reconnaissance satellite on Sunday morning, Jan. 17 at 10:42:18 a.m. PST (1:42:18 EST) from Space Launch Complex 4 (SLC 4) on Vandenberg Air Force Base (VAFB) in California, which was the primary goal of the mission.
SpaceX’s own secondary goal was to recover the first stage intact to demonstrate rocket reusability.
This was SpaceX’s third try at a barge landing following two endeavors in 2015.
And SpaceX did just accomplish a historic first ever ground soft landing and intact first stage rocket recovery following the ‘Return-to-Flight’ Falcon 9 launch on Dec. 21, 2015 from Cape Canaveral.
Two prior SpaceX attempts at a precision landing on the autonomous spaceport drone ship (ASDS) barge came very close with pinpoint approaches to the oceangoing vessel in the Atlantic Ocean. But the rocket tipped somewhat sideways in the final moments and was destroyed in a hard landing.
Musk’s space vision is to radically slash the costs of launching people and payloads to space by recovering and reflying rockets – built individually at great expense – rather than completely discarding them after a single use.
So after separating from the second stage, the first stage Merlin 1D engine was reignited for propulsive maneuvers guiding the booster back to the football field sized droneship, located nearly two hundred miles off the California coast.
The booster successfully soft landed almost dead center on the ASDS named “ Just Read The Instructions” – which put out to sea the day before launch.
Although SpaceX initially thought the booster made a hard landing, further data review revealed that the rocket in fact made a successful soft landing.
“After further data review, stage landed softly but leg 3 didn’t lockout,” SpaceX noted on Twitter. “Was within 1.3 meters of droneship center.
SpaceX plans many future attempts at rocket recovery at sea and on land and Musk is “very optimistic” on the chances, despite the last second tipover and explosion!
“Well, at least the pieces were bigger this time! Won’t be last RUD [rapid unplanned destruction], but am optimistic about upcoming ship landing,” tweeted Musk.
