KENNEDY SPACE CENTER, FL – Just hours before blastoff, the first ever SpaceX Falcon 9 set to soar to the space station from historic pad 39A at NASA’s Kennedy Space Center (KSC), the rocket went vertical below delightfully dark skies on the Florida Space Coast.

UPDATE- The launch was scrubbed until Feb. 19 after a hold was called to deal with a thrust vector control issue. Story updated

Packed with over a thousand pounds of research experiments and science instruments probing the human body and our home planet from the heavens above, the Falcon 9 rocket is poised for liftoff at 9:38 a.m., Sunday morning, Feb. 19, from Launch Complex 39A (LC-39A) at KSC.

Everything is on track for Sunday’s launch of the 229 foot tall (70 meter) SpaceX Falcon 9 on the NASA contracted SpaceX CRS-10 resupply mission for NASA to the million pound orbiting lab complex.

And the weather looks promising at this time.

At a meeting with reporters at pad 39A on Friday, Feb. 17, SpaceX President Gwynne Shotwell confirmed the success of the static fire test of the two stage rocket and all nine first stage Merlin 1D engines conducted on Sunday afternoon, Feb. 12 – minus the SpaceX Dragon cargo freighter payload.

The successful test firing of the engines cleared the path to orbit for liftoff of Dragon on a critical cargo flight for NASA to deliver over two and a half tons of supplies and science on the CRS-10 resupply mission to the six person crew living and working aboard the International Space Station (ISS).

Shotwell then said technicians integrated with the unmanned Dragon CRS-10 cargo freighter with the Falcon 9 rocket.

The 22 story tall rocket rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A on Thursday morning using a dedicated transporter-erector, so ground crews could begin final preparations for the Saturday morning blastoff. Now reset to Sunday.

Thousands and thousands of spectators from across the globe, local residents, media and scientists and engineers and their families have flocked to the Florida Space Coast, filling area hotels to witness the historic maiden blastoff of a Falcon 9 from seaside pad 39A at KSC at 9:38 a.m. EST Sunday, Feb. 19.

SpaceX will also attempt to achieve a secondary mission goal of landing the 156 foot tall first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 40.

If you can’t personally be here to witness the launch in Florida, you can also watch NASA’s live coverage on NASA Television and the agency’s website.

The SpaceX/Dragon CRS-10 launch coverage will be broadcast on NASA TV beginning at 8:30 a.m. EDT Saturday, Feb. 18, with additional commentary on the NASA launch blog.

SpaceX will also feature their own live webcast beginning approximately 20 minutes before launch at 9:41 a.m. EDT.

You can watch the launch live at NASA TV at – http://www.nasa.gov/nasatv

You can also watch the launch live at SpaceX Webcast at – spacex.com/webcast

The launch window is instantaneous, meaning that any delays due to weather or technical issues results in a minimum 1 day postponement.

The long awaited FAA launch license was finally granted at the last minute on Friday afternoon – less than 24 hours before launch.

The weather outlook currently is improving from earlier in the week and looks good for Saturday morning with a 70% chance of favorable condition at launch time. The concerns are for thick clouds according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base.

In case of a scrub for any reason on Feb. 18, the backup launch opportunity is 9:38 a.m. Sunday, Feb. 19. with NASA TV coverage starting at about 8:10 a.m. EDT.

CRS-10 marks only the third time SpaceX has attempted a land landing of the 15 story tall first stage booster.

Shotwell confirmed they are attempting the secondary mission of landing the 156 foot tall first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1, located about 9 miles south of launch pad 39a.

And it won’t take long to learn the results – the ground landing at LZ -1 will take place about 9 minutes after liftoff.

This marks the first time any fully integrated rocket has stood on pad 39A for a scheduled launch since the retirement of NASA’s Space Shuttles in July 2011 on the STS-135 mission to the space station.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions as far back as the 1960s.

Dragon is carrying more than 5500 pounds of equipment, gear, food, crew supplies, hardware and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload in support of the Expedition 50 and 51 crew members.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere.

The LIS lightning mapper will measure lightning from the altitude of the ISS. NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

The research supplies and equipment brought up by Dragon will support over 250 scientific investigations to advance knowledge about the medical, psychological and biomedical challenges astronauts face during long-duration spaceflight.

At T Minus 1 Day from ISS Liftoff SpaceX Rolls Falcon 9 to KSC Pad 39A – Feb. 18 Ignition Hinges on FAA License Approval

KENNEDY SPACE CENTER, FL – Its getting down to the wire at T Minus 1 Day from liftoff for SpaceX and NASA as a Falcon 9 rocket was rolled out to historic Launch Complex 39A today, Feb 16, and the Feb. 18 ignition to the space station hinges on the approval of a launch license yet to be granted, the Federal Aviation Administration (FAA) confirmed late today to Universe Today.

“My previous background still applies,” FAA spokesman Hank Price confirmed to Universe Today.

“The FAA is working closely with SpaceX to ensure the activity described in the application meets all applicable regulations for a launch license.”

“The FAA will continue to work with SpaceX to provide a license determination in a timely manner.”

Blastoff of the Falcon 9 from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 10:01 a.m. EST Saturday, Feb. 18.

NASA plans live coverage of the launch beginning at 8:30 a.m. on NASA Television and the agency’s website.

SpaceX currently has license applications pending with the FAA for both the NASA cargo launch and pad 39A. No commercial launch can take place without FAA approval.

No License, No Launch – that’s the bottom line!

Assuming the FAA grants a launch license at the last minute on Friday the weather outlook currently is iffy for Saturday with a 60% chance of favorable conditions at launch time. The concerns are for rains and clouds according to Air Force weather forecasters.

In case of a scrub for any reason on Feb. 18, the backup launch opportunity is 9:38 a.m. Sunday, Feb. 19.

Technically all appears to be on track for the historic first launch of a Falcon 9 from pad 39A pending further reviews and updates from NASA and SpaceX on Friday.

After a successful static fire test of the two stage rocket and all nine first stage Merlin 1D engines on Sunday afternoon, Feb. 12, the path to orbit was cleared for a critical Dragon cargo flight for NASA to deliver over two and a half tons of science and supplies on the CRS-10 resupply mission to the six person crew living and working on the International Space Station (ISS).

The SpaceX Falcon 9 rocket was then integrated with the unmanned Dragon CRS-10 cargo freighter was rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A this morning using a dedicated transporter-erector, so crew could begin final preparation for the Saturday morning blastoff.

From atop KSC pad 39B I witnessed the rocket residing horizontally atop pad 39A as technicians further moved the rocket to launch position.

The 22 story tall Falcon 9/Dragon vehicle was erected to vertical launch position later this afternoon at about 4:50 p.m. to conduct additional ground checks and testing.

It will again be lowered to the horizontal position, so that late load cargo items can be stowed inside the Dragon spaceship on Friday before raising the rocket again into the final launch configuration.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions as far back as the 1960s.

SAGE III will measure stratospheric ozone, aerosols, and other trace gases by locking onto the sun or moon and scanning a thin profile of the atmosphere.

The LIS lightning mapper will measure lightning from the altitude of the ISS. NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

About 10 minutes after launch, Dragon will reach its preliminary orbit, deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.

As a secondary objective SpaceX s planning to attempt to land its Falcon 9 first stage on land at Landing Zone 1 at Cape Canaveral Air Force Station.

‘Astronauts Shane Kimbrough of NASA and Thomas Pesquet of ESA (European Space Agency) will use the station’s robotic arm to capture Dragon when it arrives at the space station after its two-day journey. The spacecraft will be berthed to the Earth-facing port on the Harmony module. The following day, the space station crew will pressurize the vestibule between the station and Dragon, then open the hatch that leads to the forward bulkhead of Dragon,’ according to NASA.

Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

SpaceX Falcon 9 Breathes First Fire at KSC Pad 39A – Successful Static Fire Test Paves Path to Feb. 18 ISS Launch

SPACE VIEW PARK/KENNEDY SPACE CENTER, FL – For the first time in more than half a decade, a rocket came to life at NASA’s Kennedy Space Center when a SpaceX Falcon 9 breathed her first fire at historic pad 39A today, Sunday, Feb. 12 – successfully completing a critical static test firing of the first stage engines that opens the door to a launch to the space station next weekend for NASA.

The hot fire test generated a huge plume of smoke exhausting out the north side of the flame trench of Launch Complex 39A at approximately 4:30 p.m. EST, Feb. 12.

The hold down engine test with the erected rocket involved the ignition of all nine Merlin 1D first stage engines generating some 1.7 million pounds of thrust at pad 39A – which has been repurposed from its days as a shuttle launch pad.

The Merlin 1D engines fired for about 3 seconds while the two stage rocket was restrained on the pad.

SpaceX confirmed the test via social media shortly after it took place.

“First static fire test of Falcon 9 at historic launch complex 39A completed in advance of Dragon’s upcoming mission to the @Space_Station,” SpaceX tweeted in a very brief announcement.

I watched excitedly from a public viewing spot at Space View Park in Titusville as the exhaust plume grew quickly in size to a gigantic grey-white colored mushroom cloud of smoke and ash, heaving out the north side of the flame trench silent since the shuttle era.

Then just as quickly the smoke cloud dissipated completely within about 10 minutes leaving barely a trace of what we can expect to see soon.

Titusville offers a prime viewing location for anyone interested in traveling to the Florida Space Coast to see this Falcon 9 launch in person.

The test confirms that both the first stage engines and the rocket are suited for liftoff. Over the past few days, launch teams also tested the pad equipment, raised and lowered the rocket and conducted fit checks of the rocket at the pad.

The test had been delayed several days as technicians coped with issues until all was right to carry out the static fire test.

The positive outcome paves the path for a Falcon 9.Dragon blastoff as soon as next Saturday.

This marks the first time any rocket has stood on pad 39A and fired its engines since the retirement of NASA’s Space Shuttles in July 2011 on the STS-135 mission to the space station.

Liftoff of the Falcon 9 is slated for no earlier than next Saturday, 18 Feb 2017 on a critical cargo flight for NASA to deliver over two and a half tons of science and supplies to the six person crew living and working on the International Space Station (ISS).

The rocket – minus the payload comprising the Dragon cargo spacecraft – was rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A on Friday morning using a dedicated transporter-erector.

After the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and the Dragon resupply ship will be integrated on top.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.

Dragon will be loaded with more than 5500 pounds of equipment, gear, food, supplies and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload.

SpaceX was previously employing pad 40 on Cape Canaveral Air Force Station for Falcon 9 launches to the ISS as well as commercial launches.

But pad 40 suffered severe damage following the unexpected launch pad explosion on Sept 1, 2016 that completely destroyed a Falcon 9 and the $200 million Amos-6 commercial payload during a prelaunch fueling test.

An accident investigation revealed that a second stage helium tank burst due to friction ignition during the fueling test.

SpaceX modified the fueling procedures as a short term fix and is working on redesigning the second stage as a long term fix.

SpaceX is working to repair and refurbish pad 40. It is not known when it will be ready to resume launches.

Thus SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, speeding up the refurbishing and repurposing work which at last is sufficient to launch rockets again.

Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

First SpaceX Falcon 9 Erected at Historic Launch Pad 39A for Feb. 18 Blastoff

KENNEDY SPACE CENTER, FL – The first SpaceX Falcon 9 rocket ever to grace historic launch pad 39A at NASA’s Kennedy Space Center in Florida was erected this afternoon, Friday, Feb. 10, to prepare the booster for a critical static fire sometime Saturday, and a launch to the space station next weekend – if all goes well.

This marks the first time any rocket has stood on pad 39A since the retirement of NASA’s Space Shuttles in July 2011.

The rocket – minus the payload comprising the Dragon cargo spacecraft – was rolled out of the SpaceX processing hangar at the perimeter fence and then up the incline to the top of pad 39A this morning using a dedicated transporter-erector.

The booster was then hoisted into launch position this afternoon.

The scene was viewed by spectators including my space journalist colleague Jeff Seibert.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.

SpaceX CEO Elon Musk also posted a photo on instagram with this caption:

“Falcon 9 rocket now vertical at Cape Canaveral on launch complex 39-A. This is the same launch pad used by the Saturn V rocket that first took people to the moon in 1969. We are honored to be allowed to use it.”

After the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and the Dragon resupply ship will be integrated on top.

During the brief static fire test, all 9 Merlin 1D first stage engines are ignited for a few seconds to confirm they and the rocket are suited for liftoff while hold down clamps restrain the rocket on the pad.

Dragon will be loaded with more than 5500 pounds of equipment, gear, food, supplies and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload.

Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

SpaceX Awaits FAA Falcon 9 Launch License for 1st Pad 39A Blastoff on NASA ISS Cargo Flight

KENNEDY SPACE CENTER, FL – With liftoff tentatively penciled in for mid-February, SpaceX still awaits FAA approval of a launch license for what will be the firms first Falcon 9 rocket to launch from historic pad 39A at the Kennedy Space Center – on a critical NASA mission to resupply the space station – the Federal Aviation Administration (FAA) confirmed today to Universe Today.

“The FAA is working closely with SpaceX to ensure the activity described in the application meets all applicable regulations for a launch license,” FAA spokesman Hank Price confirmed to Universe Today.

As of today, Feb. 7, SpaceX has not yet received “a license determination” from the FAA – as launch vehicle, launch pad and payload preparations continue moving forward for blastoff of the NASA contracted flight to carry science experiments and supplies to the International Space Station (ISS) aboard a SpaceX cargo Dragon atop an upgraded SpaceX Falcon 9 rocket from Launch Complex 39A on the Florida Space Coast.

“The FAA will continue to work with SpaceX to provide a license determination in a timely manner,” Price told me.

SpaceX currently has license applications pending with the FAA for both the NASA cargo launch and pad 39A. No commercial launch can take place without FAA approval.

The goal of the 22-story tall SpaceX Falcon 9 is to carry an unmanned Dragon cargo freighter for the NASA customer on the CRS-10 resupply mission to the International Space Station (ISS).

Dragon will be loaded with more than two tons of equipment, gear, food, supplies and NASA’s Stratospheric Aerosol Gas Experiment III (SAGE III) ozone mapping science payload.

The historic NASA launch pad was formerly used to launch both America’s space shuttles and astronauts on Apollo/Saturn V moon landing missions.

SpaceX, founded by billionaire CEO Elon Musk, leased Launch Complex 39A from NASA back in April 2014 and is modifying and modernizing the pad for unmanned and manned launches of the Falcon 9 as well as the Falcon Heavy.

The role of the FAA is to license commercial launches and protect the public.

“The FAA licenses commercial rocket launches and reentries to ensure the protection of public health and safety,” Price elaborated.

This FAA license situation is similar to that for last month’s Falcon 9 ‘Return to Flight’ launch from California, where the SpaceX approval was granted only days before liftoff of the Iridium-1 mission.

Last week SpaceX announced a shuffled launch schedule, whereby the NASA cargo flight on the CRS-10 resupply mission was placed first in line for liftoff from pad 39A – ahead of a commercial EchoStar communications satellite.

The aerospace company said the payload switch would allow additional time was to complete all the extensive ground support work and pad testing required for repurposing seaside Launch Complex 39A from launching the NASA Space Shuttle to the SpaceX Falcon 9.

The inaugural Falcon 9 blastoff from pad 39A has slipped repeatedly from January into February 2017.

The unofficial most recently targeted ‘No Earlier Than’ NET date for CRS-10 has apparently slipped from NET Feb 14 to Feb 17.

CRS-10 counts as SpaceX’s tenth cargo flight to the ISS since 2012 under contract to NASA.

Further launch postponements are quite possible at any time and NASA is officially stating a goal of “NET mid-February” – but with no actual target date specified.

Crews have been working long hours to transform and refurbish pad 39A and get it ready for Falcon 9 launches. Furthermore, a newly built transporter erector launcher was seen raised at the pad multiple times in recent weeks. The transporter will move the rocket horizontally up the incline at the pad, and then erect it vertically for launch.

SpaceX was previously employing pad 40 on Cape Canaveral Air Force Station for Falcon 9 launches to the ISS as well as commercial launches.

Thus SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, and the refurbishing and repurposing work is not yet complete.

Pad 39A has lain dormant for launches for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

To date SpaceX has not rolled a Falcon 9 rocket to pad 39A, not raised it to launch position, not conducted a fueling exercise and not conducted a static fire test. All the fit checks with a real rocket remain to be run.

Once the pad is ready, SpaceX plans an aggressive launch schedule in 2017.

“The launch vehicles, Dragon, and the EchoStar satellite are all healthy and prepared for launch,” SpaceX stated.

The history making first use of a recycled Falcon 9 carrying the SES-10 communications satellite could follow as soon as March or April, if all goes well – as outlined here.

Used SpaceX Booster Set for Historic 1st Reflight is Test Fired in Texas

The first orbit class SpaceX rocket that will ever be reflown to launch a second payload to space was successfully test fired by SpaceX engineers at the firms Texas test facility last week.

The once fanciful dream of rocket recycling is now closer than ever to becoming reality, after successful completion of the static fire test on a test stand in McGregor, Texas, paved the path to relaunch, SpaceX announced via twitter.

The history making first ever reuse mission of a previously flown liquid fueled Falcon 9 first stage booster equipped with 9 Merlin 1D engines could blastoff as soon as March 2017 from the Florida Space Coast with the SES-10 telecommunications satellite, if all goes well.

The booster to be recycled was initially launched in April 2016 for NASA on the CRS-8 resupply mission under contract for the space agency.

“Prepping to fly again — recovered CRS-8 first stage completed a static fire test at our McGregor, TX rocket development facility last week,” SpaceX reported.

The CRS-8 Falcon 9 first stage booster successfully delivered a SpaceX cargo Dragon to the International Space Station (ISS) in April 2016.

The Falcon 9 first stage was recovered about 8 minutes after liftoff via a propulsive soft landing on an ocean going droneship in the Atlantic Ocean some 400 miles (600 km) off the US East coast.

SpaceX, founded by billionaire and CEO Elon Musk, inked a deal in August 2016 with telecommunications giant SES, to refly a ‘Flight-Proven’ Falcon 9 booster.

Luxembourg-based SES and Hawthrone, CA-based SpaceX jointly announced the agreement to “launch SES-10 on a flight-proven Falcon 9 orbital rocket booster.”

Exactly how much money SES will save by utilizing a recycled rocket is not known. But SpaceX officials have been quoted as saying the savings could be between 10 to 30 percent.

The SES-10 launch on a recycled Falcon 9 booster was originally targeted to take place before the end of 2016.

That was the plan until another Falcon 9 exploded unexpectedly on the ground at SpaceX’s Florida launch pad 40 during a routine prelaunch static fire test on Sept. 1 that completed destroyed the rocket and its $200 million Amos-6 commercial payload on Cape Canaveral Air Force Station.

The Sept. 1 launch pad disaster heavily damaged the SpaceX pad and launch infrastructure facilities at Space Launch Complex-40 on Cape Canaveral Air Force Station in Florida.

Pad 40 is still out of commission as a result of the catastrophe. Few details about the pad damage and repair work have been released by SpaceX and it is not known when pad 40 will again be certified to resume launch operations.

Therefore SpaceX ramped up preparations to launch Falcon 9’s from the firms other pad on the Florida Space Coast – namely historic Launch Complex 39A which the company leased from NASA in 2014.

Pad 39A is being repurposed by SpaceX to launch the Falcon 9 and Falcon Heavy rockets. It was previously used by NASA for more than four decades to launch Space Shuttles and Apollo moon rockets.

But SES-10 is currently third in line to launch atop a Falcon 9 from pad 39A.

The historic first launch of a Falcon 9 from pad 39A is currently slated for no earlier than Feb. 14 on the CRS-10 resupply mission for NASA to the ISS – as reported here.

The EchoStar 23 comsat is slated to launch next, currently no earlier than Feb 28.

SES-10 will follow – if both flights go well.

SpaceX successfully launched SES-9 for SES in March 2016.

Last July, SpaceX engineers conducted a test firing of another recovered booster as part of series of test examining long life endurance testing. It involved igniting all nine used first stage Merlin 1D engines housed at the base of a used landed rocket.

The Falcon 9 first stage generates over 1.71 million pounds of thrust when all nine Merlin engines fire up on the test stand for a duration of up to three minutes – the same as for an actual launch.

SpaceX Shuffles Falcon 9 Launch Schedule, NASA Gets 1st Launch from Historic KSC Pad 39A

KENNEDY SPACE CENTER, FL – SpaceX announced Sunday (Jan. 29) a significant shuffle to the Falcon 9 launch schedule, saying that a key NASA mission to resupply the space station is moving to the head of the line and will now be their first mission to launch from historic pad 39A at the Kennedy Space Center – formerly used to launch space shuttles.

The late breaking payload switch will allow SpaceX, founded by billionaire CEO Elon Musk, additional time to complete all the extensive ground support work and pad testing required for repurposing seaside Launch Complex 39A from launching the NASA Space Shuttle to the SpaceX Falcon 9.

Blastoff of the 22-story tall SpaceX Falcon 9 carrying an unmanned Dragon cargo freighter with NASA as customer on the CRS-10 resupply mission to the International Space Station (ISS) could come as soon as mid-February, said SpaceX.

“SpaceX announced today that its first launch from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida will be the CRS-10 mission to the International Space Station,” said SpaceX in a statement.

CRS-10 counts as SpaceX’s tenth cargo flight to the ISS since 2012 under contract to NASA.

Crews have been working long hours to modify pad 39A and get it ready for Falcon 9 launches. Also, the newly built transporter erector launcher was seen raised at the pad multiple times in recent days. The transporter will move the rocket horizontally up the incline at the pad, and then erect it vertically.

“This schedule change allows time for additional testing of ground systems ahead of the CRS-10 mission,” SpaceX announced in a statement.

The surprise switch in customers means that the previously planned first Falcon 9 launch from pad 39A of the commercial EchoStar 23 communications satellite is being pushed off to a later date – perhaps late February.

Until now, EchoStar 23 was slated to be the first satellite launched by a Falcon 9 from Launch Complex 39A on NASA’s Kennedy Space Center. It could have come as soon as by the end of this week.

However, the Falcon 9 launch date from pad 39A has slipped repeatedly in January, with this week on Feb. 3 as the most recently targeted ‘No Earlier Than’ NET date.

SpaceX successfully resumed launches of the Falcon 9 earlier this month when the first flock of 10 Iridium NEXT mobile voice and data relay satellites blasted off on the Iridium 1 mission from Vandenberg Air Force Base in California on Jan. 14, 2017.

NASA now gets the first dibs for using pad 39A which has lain dormant for nearly six years since Space Shuttle Atlantis launched on the final shuttle mission STS 135 in July 2011.

SpaceX leased pad 39A from NASA for launches of the Falcon 9 and Falcon Heavy back in April 2014 and was already employing pad 40 on Cape Canaveral Air Force Station for Falcon 9 launches to the ISS.

The last Dragon resupply mission to the ISS blasted off on July 18, 2016 on the CRS-9 mission. The Falcon 9 first stage was also successfully recovered via a propulsive soft landing back at the Cape at night.

The last successful Falcon 9 launch from Space Launch Complex-40 took place on Aug. 14, 2016, carrying the JCSAT-16 Japanese communications satellite to orbit.

But following the unexpected launch pad explosion on Sept 1, 2016 that completely destroyed a Falcon 9 and the $200 million Amos-6 commercial payload during a prelaunch fueling test, pad 40 suffered extensive damage.

Furthermore it is not known when the pad will be ready to resume launches.

So SpaceX has had to switch launch pads for near term future flights and press pad 39A into service much more urgently, and the refurbishing and repurposing work is not yet complete.

Thus the current launch target of mid-February for CRS-10 remains a target date and not a firm launch date. EchoStar 23 is next in line.

“The launch is currently targeted for no earlier than mid-February,” SpaceX elaborated.

“Following the launch of CRS-10, first commercial mission from 39A is currently slated to be EchoStar XXIII.”

Once the pad is ready, SpaceX plans an aggressive launch schedule in 2017.

“The launch vehicles, Dragon, and the EchoStar satellite are all healthy and prepared for launch,” SpaceX stated.

The history making first use of a recycled Falcon 9 carrying the SES-10 communications satellite could follow as soon as March, if all goes well.

SpaceX Falcon 9 Comes Roaring Back to Life with Dramatically Successful Iridium Fleet Launch and Ocean Ship Landing

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 mobile voice and data relay satellites to orbit while simultaneously recovering the first stage on a ship at sea off the west coast of California.

BREAKING NEWS – check back for updates.

The primary goal of SpaceX’s Falcon 9 launch from Space Launch Complex 4E on Vandenberg Air Force Base in California was to deploy the payload of the first ten Iridium Next communication satellites to low Earth orbit on the Iridium-1 mission.

“Thanks @elonmusk – a perfect flight! Loved watching sats deploy with you in the control room,” tweeted Matt Desch, Iridium Communications CEO, soon after receiving full confirmation that all 10 Iridium NEXT satellites were successfully deployed from their second stage satellite dispensers.

“More to go, but now to celebrate!!”

The inaugural ten will serve as the vanguard of a fleet that will eventually comprise 81 satellites.

Today’s successful blastoff took place barely four and a half months after another Falcon 9 and its $200 million Israeli commercial payload were suddenly destroyed during a prelaunch fueling test on the Florida Space Coast on Sept. 1, 2016.

Another launch failure would have dealt a devastating blow to confidence in SpaceX’s hard won reputation.

The Sept. 1, 2016 calamity was the second Falcon 9 failure within 15 months time. Both occurred inside the second stage and called into question the rockets reliability.

The 229-foot (70-meter) Falcon 9 rocket was rolled out from its processing hangar to the launch pad and raised vertically yesterday.

Today’s entire land, landing and satellite deployment event was shown live on a SpaceX hosted webcast. It offered extremely sharp views of Saturdays on time liftoff at 9:54:34 a.m. PST or 12:54:34 p.m. EST, and unbelievably clear images of the first stage descending back to Earth towards a tiny drone ship.

“Overall a wonderfully nominal mission,” gushed the SpaceX commentator during the webcast.

Since the Iridium 1 mission only had an instantaneous launch opportunity precisely at 9:54:34 a.m. PST or 12:54:34 p.m. EST, there was no margin for any technical or weather delays. And none happened. Although an errant boat had to be quickly escorted out of the exclusion zone less than 20 minutes before blastoff.

Confirmation of a successful deployment of all 10 Iridium NEXT satellites came at about T plus 1 hour and 17 minutes after liftoff from Vandenberg.

“So, so excited – finally breathing again!” tweeted Desch.

“Thanks for all the great vibes – I felt it! All 10 sats deployed; good orbit; good telemetry! WOW.”

The mobile relay satellites were delivered into a circular orbit at an altitude of 625 kilometers (388 miles) above Earth.

They were released one at a time from a pair of specially designed satellite dispensers at approximately 100 second intervals.

“It was a clean sweep, 10 for 10,” said SpaceX commentator John Insprucker during the live webcast.

“All the bridge wires show open, and that is a conclusion of the primary mission today, a great one for the first stage, second stage, and the customer’s satellites deployed into a good orbit.”

The Iridium NEXT satellites were built by Thales Alenia and Orbital ATK.

In the final moments before the propulsive landing, you could read the lettering on the “Just Read the Instructions” drone ship as the engine was firing to slow the descent and the landing legs deployed.

Really there was no cutout or loss of signal the whole way down. So the world could watch every key moment as it happened in real time.

The first stage softly landed approx. 8 minutes and 18 seconds after the California liftoff.

“First stage has landed on Just Read the Instructions,” SpaceX tweeted post landing.

This was the first launch by SpaceX since last August from the Florida Space Coast, and it came off without a hitch.

Iridium 1 is the first of seven planned Falcon 9 launches to establish the Iridium NEXT constellation which will eventually consist of 81 advanced satellites.

At least 70 will be launched by SpaceX.

The inaugural launch of the advanced Iridium NEXT satellites will start the process of replacing an aging Iridium fleet in orbit for nearly two decades.

SpaceX Set for High Stakes Falcon 9 Blastoff Resumption with Iridium Satellite Fleet on Jan. 14 – Watch Live

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.

Barely four and a half months after another Falcon 9 and its $200 million Israeli commercial payload were suddenly destroyed during a prelaunch fueling test on the Florida Space Coast on Sept. 1, 2016, SpaceX says all systems are GO for the ‘Return to Flight’ launch of a new Falcon 9 on the Iridium-1 mission from the California coast tomorrow.

Another launch failure would deal a devastating blow to confidence in SpaceX’s hard won reputation – so ‘Failure is Not an Option’ as they say in the space business.

The Sept. 1, 2016 calamity was the second Falcon 9 failure within 15 months time. Both occurred inside the second stage and called into question the rockets reliability.

The 229-foot (70-meter) Falcon 9 rocket has been rolled out from its processing hangar to the launch pad and raised vertically.

“Beautiful picture of our ride to space tomorrow on the launch pad this morning!” tweeted Matt Desch, Iridium Communications CEO, featuring the lead photo in this story.

A license for permission to proceed with the launch originally last Sunday was only granted by the FAA last Friday, Jan. 6. But poor California weather in the form of stormy rains and high winds forced further delays to Saturday.

Today, Friday the 13th, it’s T-Minus 1 Day to the inaugural launch of the advanced Iridium NEXT voice and data relay satellites.

Liftoff of the SpaceX Falcon 9 with the payload of 10 identical next generation Iridium NEXT communications satellites is slated for 9:54:39 am PST or 5:54:39 pm UTC from Space Launch Complex 4E on Vandenberg Air Force Base in California.

The Iridium 1 mission only has an instantaneous launch opportunity precisely at 9:54:34 a.m. PST or 12:54:34 p.m. EST.

You can watch the launch live via a SpaceX webcast starting about 20 minutes prior to the planned liftoff time:

The launch will be broadcast at : http://www.spacex.com/webcast

Weather forecasters currently predict about a 60 percent chance of favorable conditions at launch time.

Sunday, Jan. 15 is available as a back-up launch opportunity in case of a delay for any reason including technical and weather related issues.

“The teams from Iridium, SpaceX and our partners are in the homestretch for the first launch of the Iridium NEXT satellite constellation,” said satellite owner Iridium Communications.

Meanwhile the launch teams have completed the countdown dress rehearsal’ and Launch Readiness Review in anticipation of the morning liftoff.

“Final preparations are being made for tomorrow’s inaugural launch, and with that comes a number of high-stakes verifications, involving all parties. Traditionally referred to as the ‘countdown dress rehearsal’ and ‘Launch Readiness Review’ (LRR), these milestones represent the final hurdles to clearing the path for the January 14th launch.”

“The countdown dress rehearsal and LRR include several prelaunch inspections and quality control measures. These include final clearances for the SpaceX Falcon 9 rocket, Iridium NEXT payload, SpaceX and Iridium® ground infrastructure and associated team member responsibilities.”

Iridium says that every precaution has been taken to ensure a successful launch.

“There are so many variables that need to be considered when finalizing launch preparations, and a slight deviation or unexpected behavior by any of them can jeopardize the launch integrity,” said Iridium COO Scott Smith, in a statement.

“We’ve perfected the necessary procedures, taken every precaution we can imagine, and tomorrow, after what has felt like centuries, we’ll take the first step on a long-awaited journey to revolutionize satellite communications. The success of today’s events has brought us to an apex moment.”

Iridium 1 is the first of seven planned Falcon 9 launches to establish the Iridium NEXT constellation which will eventually consist of 81 advanced satellites.

At least 70 will be launched by SpaceX.

The inaugural launch of the advanced Iridium NEXT satellites will start the process of replacing an aging Iridium fleet in orbit for nearly two decades.

After the Sept .1 calamity SpaceX conducted a four month long investigation seeking to determine the root cause.

And it was just last Friday, Jan. 6, that the FAA finally granted SpaceX a license to launch the ‘Return to Flight’ Falcon 9 mission – as I confirmed with the FAA.

“The FAA accepted the investigation report on the AMOS-6 mishap and has closed the investigation,” FAA spokesman Hank Price confirmed to Universe Today.

“SpaceX applied for a license to launch the Iridium NEXT satellites from Vandenberg Air Force Base. The FAA has granted a license for that purpose.”

The SpaceX investigation report into the total loss of the Falcon 9 rocket and AMOS-6 payload has not been released at this time. The FAA has oversight responsibility to encourage, facilitate, and promote U.S. commercial space transportation and ensure the protection of public safety.

In addition to the launch, SpaceX plans to continue its secondary objective of recovering the Falcon 9 first stage via a propulsive soft landing – as done several times previously and witnessed by this author.

The Iridium-1 mission patch featured herein highlights both the launch and landing objectives.

The goal is to eventually recycle and reuse the first stage – and thereby dramatically slash launch costs per Musk’s vision.

This Falcon 9 has been outfitted with four landing legs and grid fins for a controlled landing on a tiny barge prepositioned in the Pacific Ocean several hundred miles off the west coast of California.

Poor Weather Pushes SpaceX Return Debut with Revolutionary Iridium Relay Sats to Jan. 14

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.

Earlier indications of a nearly weeks long launch delay from Monday, Jan. 9 to next Saturday morning, Jan. 14, were officially confirmed today, Jan. 8, by SpaceX and their Iridium Communications customer.

“Launch moving due to high winds and rains at Vandenberg,” SpaceX announced today, Jan. 8.

Liftoff of the SpaceX Falcon 9 with the payload of 10 identical next generation Iridium NEXT communications satellites had been slated for 10:22 am PST (1:22 pm EST), Jan. 9, 2017 from Space Launch Complex 4E on Vandenberg Air Force Base in California.

The advanced next satellites will start the process of replacing an aging Iridium fleet in orbit for nearly two decades.

And it was less than 48 hours ago on Friday, Jan. 6, that the FAA finally granted SpaceX a license to launch the ‘Return to Flight’ Falcon 9 mission – as I confirmed with the FAA here.

“The FAA accepted the investigation report on the AMOS-6 mishap and has closed the investigation,” FAA spokesman Hank Price confirmed to Universe Today.

“SpaceX applied for a license to launch the Iridium NEXT satellites from Vandenberg Air Force Base. The FAA has granted a license for that purpose.”

The private rocket – developed by CEO Elon Musk and his company – has been grounded for four months since a catastrophic launch pad explosion last September suddenly destroyed another Falcon 9 and its $200 million Israeli owned satellite during a prelaunch fueling test on the Florida Space Coast.

The Sept. 1, 2016 calamity was the second Falcon 9 failure within 15 months time. Both occurred inside the second stage and called into question the rockets reliability.

The prognosis of a week of bad California weather had been known for some time and finally prompted an official announcement just 24 hours before the hoped for launch.

“With high winds and rain in the forecast at Vandenberg Air Force Base, the first launch of 10 Iridium NEXT satellites is now planned for January 14th at 9:54:34 am PST with a back-up date of January 15th,” Iridium officials elaborated in a statement.

The mission, known as Iridium 1, has an instantaneous launch opportunity at 9:54:34 a.m. PST (12:54:34 p.m. EST).

Next Sunday, Jan. 15 is available as a back-up launch opportunity in case of a delay for any reason including technical and weather related issues.

Furthermore, humorous pleas by Iridium CEO Matt Desch for divine intervention went unheeded !

“Can now confirm: new launch date Jan 14 at 9:54am pst. Bad weather the cause. Anti-rain dances didn’t work – oh well. Cal needs rain?” said Iridium CEO Matt Desch when he threw in the towel this morning by tweet.

Things change fast and furious in the rocket business, and flexibility is the name of the game if you want to survive the frequently changing landscape.

A contributing factor to the delay is a range conflict with an upcoming Atlas rocket launch for the U.S National Reconnaissance Organization (NRO) at Vandenberg AFB.

“Other range conflicts this week results in next available launch date being Jan 14,” SpaceX confirmed.

The United Launch Alliance Atlas V is scheduled to launch the super secret NROL-79 spy satellite for the NRO on Jan. 26.

Prior to the launch, ULA must conduct a wet dress rehearsal (WDR) of the Atlas V by fueling it with propellants to confirm its readiness to launch.

The clandestine NROL-79 intelligence-gathering payload is critical to US national defense. Surly it was manufactured over a time span of several years at an unknown classified cost probably amounting to billions of dollars.

For the Iridium – 1 mission the 229-foot (70-meter) Falcon 9 will carry a fleet of ten Iridium NEXT mobile voice and data relay satellites to orbit from Vandenberg Air Force Base, Ca, for Iridium Communications.

Iridium 1 is the first of seven planned Falcon 9 launches to establish the Iridium NEXT constellation which will eventually consist of 81 advanced satellites.

The FAA license approved on Jan. 6 covers all seven launches.

“Space Explorations Technologies is authorized to conduct seven launches of Falcon 9 version 1.2 vehicles from Space Launch Complex 4E at Vandenberg Air Force Base with each flight transporting ten Iridium NEXT payloads to low Earth orbit.

The license also allows SpaceX to land the first stage on a droneship at sea in the Pacific Ocean.

So besides the launch, SpaceX plans to continue its secondary objective of recovering the Falcon 9 first stage via a propulsive soft landing – as done several times previously and witnessed by this author.

The Iridium-1 mission patch featured herein highlights both the launch and landing objectives.

The goal is to eventually recycle and reuse the first stage – and thereby dramatically slash launch costs per Musk’s vision.

This Falcon 9 has been outfitted with four landing lags and grid fins for a controlled landing on a tiny barge prepositioned in the Pacific Ocean several hundred miles off the west coast of California.

Desch says that all seven of his Falcon’s will be new – not reused.

“All our seven F9s are new,” Desch tweeted.

On Jan. 2, SpaceX issued a statement ascribing the Sept. 1, 2016 AMOS-6 launch pad anomaly as being traced to a failure wherein one of three high pressure helium storage tanks located inside the second stage liquid oxygen (LOX) tank of the Falcon 9 rocket suddenly burst. Cold helium is used to pressurize the propellant tanks. They provided some but not many technical details.

The failure apparently originated at a point where the helium tank “buckles” and accumulates oxygen – “leading to ignition” of the highly flammable superchilled oxygen propellant in the second stage when it came into contact with carbon fibers covering the helium tanks – also known as composite overwrapped pressure vessels (COPVs).

“Friction ignition” between the carbon fibers acting as a friction source and super chilled oxygen led to the calamitous explosion, SpaceX concluded was the most likely cause of the disaster.
