KENNEDY SPACE CENTER, FL – After postponing last week’s liftoff of the covert ‘Zuma’ spy satellite due to last minute concerns about the reliability of the payload fairing encapsulating it while poised for liftoff at KSC pad 39, SpaceX is set to at last resume launches from their previously damaged and now repaired Cape Canaveral pad 40 with a cargo resupply mission for NASA to the International Space Station (ISS) on Dec 4.

NASA and SpaceX have jointly decided to move forward with the Dragon CRS-13 cargo blastoff apparently because the mission does not involve use of the problematical payload fairing that halted last weeks planned Falcon 9 launch with the rocket and the mysterious Zuma payload.

Zuma was ready and waiting at pad 39A for the GO to launch that never came.

Then after a series of daily delays SpaceX ultimately announced a ‘stand down’ for super secret Zuma at pad 39A on Friday, Nov. 17, for the foreseeable future.

SpaceX engineers also had to deal with the after effects of a fire that broke out on a Merlin engine test stand during preparations for a hot fire test that resulted from a leak during a ‘LOX drop’ that halted testing of the Block 5 version of the Merlin 1D.

Since SpaceX’s gumdrop shaped Dragon cargo freighter launches as a stand alone aerodynamically shielded spacecraft atop the Falcon 9, it does not require additional protection from atmospheric forces and friction housed inside a nose cone during ascent to orbit unlike satellites with many unprotected exposed surfaces, critical hardware and delicate instruments.

Thus Dragon is deemed good to go since there currently appear to be no other unresolved technical issues with the Falcon 9 rocket.

“NASA commercial cargo provider SpaceX is targeting its 13th commercial resupply services mission to the International Space Station for no earlier than 2:53 p.m. EST Monday, Dec. 4,” NASA announced on the agency blog and social media accounts.

The Dec. 4 launch date for Dragon CRS-13 was announced by NASA’s space station manager Dan Hartman during the Orbital ATK Antares/Cygnus launch campaign that culminated with a successful blastoff last Sunday, Nov 12 from NASA’s Wallops Flight Facility on Virginia’s eastern shore.

But the targeted Dec 4 liftoff from Space Launch Complex 40 on Cape Canaveral Air Force Station, FL, was cast in doubt after SpaceX disclosed the payload fairing issue related launch delay on Friday.

Since last week SpaceX engineers have been busy taking the time to carefully scrutinize all the pertinent fairing data before proceeding with the top secret Zuma launch.

“We have decided to stand down and take a closer look at data from recent fairing testing for another customer,” said SpaceX spokesman John Taylor last Friday.

All of SpaceX’s launches this year from Florida’s Spaceport have taken place from NASA’s historic Launch Complex-39A at the Kennedy Space Center.

Pad 39A became SpaceX’s only operational Florida Space Coast launch pad following a catastrophic launch pad accident last year on Sept. 1, 2016 that took place during a routine fueling test that suddenly ended in a devastating explosion and fire that completely consumed the Falcon 9 rocket and Amos-6 payload and heavily damaged the pad and support infrastructure.

Since the Amos-6 accident workers raced to finish refurbishments to NASA’s long dormant pad 39A to transform into operational status and successfully launched a dozen missions this year.

Simultaneously additional crews have been hard at work to repair damaged pad 40 so that flights can resume there as soon as possible for the bulk of NASA, commercial and military contracted missions.

Meanwhile SpaceX wants to upgrade pad 39A to launch the Falcon Heavy and crewed Dragon flight. But those launches cant take place until pad 40 resumes operational status.

The Dragon CRS-13 mission was recently announced as the maiden mission for the reopening of pad 40.

Altogether Dragon CRS-13 will count as the fourth SpaceX Dragon liftoff of 2017.

The 20-foot high, 12-foot-diameter Dragon CRS-13 vessel will carry about 3 tons of science and supplies to the orbiting outpost and stay about 4 weeks.

It will be a reused Dragon that previously flew on the CRS-6 mission.

“The Dragon [CRS-13] spacecraft will spend about a month attached to the space station,” NASA said.

The prior Dragon CRS-12 resupply ship launched from pad 39A on Aug. 14, 2017 from KSC pad 39A and carried more than 6,400 pounds ( 2,900 kg) of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex.

Dragon CRS-9 was the last ISS resupply mission to launch from pad 40 on July 18, 2016.

The recently arrived Orbital ATK Cygnus cargo ship is expected to depart the station from the Earth facing Unity node on Dec. 3 to make way for Dragon’s berthing at the Harmony node.

Despite Merlin Engine Testing Anomaly SpaceX Forges Ahead With Ambitious Year End Launch Schedule Commencing Nov. 15

KENNEDY SPACE CENTER, FL – Despite suffering a significant engine testing “anomaly” and fire during test protocols with a Merlin engine that powers both stages of SpaceX’s Falcon 9 rocket, the Elon Musk founded company is forging ahead with an ambitious year end launch schedule that commences this week with blastoff of the secretive Zuma mission on Wednesday evening, Nov. 15. Clearly Musk & Co. feel it is safe to proceed.

While preparing to conduct a test firing of the most advanced Merlin engine of the type that will launch astronauts to the International Space Station (ISS) as soon as next year, something sparked the outbreak of a fire in a test bay earlier this month on a SpaceX engine test stand at their rocket development facility in McGregor, Texas, SpaceX spokesman John Taylor confirmed to Universe Today.

The resulting fire in a McGregor, Texas test bay apparently did not involve an engine explosion as technicians were getting ready to conduct an actual hot fire test. The fire may have occurred as a result of a leak while setting the Merlin engine up on a test stand during pre-test procudures. Details have not been released.

“We do not expect this to have any impact on our launch cadence,” SpaceX spokesman John Taylor told Universe Today.

“SpaceX is committed to our current manifest.”

Since the fire involved the most advanced Block 5 version of the Merlin rather than the currently used Block 4 version, SpaceX engineers and management decided they can safely and responsibly move forward with the upcoming jam packed schedule of Falcon 9 and Falcon Heavy launches, while simultaneously continuing the anomaly investigation.

2017 has been a banner year thus far for SpaceX involving 16 missions to date that ties a ULA record established in 2009.

The most recent launch took place of Oct. 30 delivering KoreaSat-5A to its intended orbit – along with a magnificent soft landing and recovery of the first stage booster on an oceangoing platform that floated ‘back in town’ days later.

The fire took place on Nov. 4, as first reported by the Washington Post on Nov. 9.

“On November 4, SpaceX experienced an anomaly during a Qualification test set up of a Merlin engine at our rocket development facility in McGregor, Texas,” SpaceX spokesman Taylor told me.

With a slew of critical launches looming starting tomorrow, Nov. 15, SpaceX had to decide quickly whether to pause or move ahead with their final planned launches of 2017 – numbering at least 4 or more and possibly including the long-awaited and long-delayed mammoth Falcon Heavy. It utilizes 27 Merlin 1D engines in the first stage cores.

SpaceX has decided to move ‘Full Speed Ahead’ – after an initial review of the fire incident which is still ongoing.

Seemingly, the fire happened during the set up period for the Merlin engine before the actual qualification engine test had begun. A leak may have occurred around the test stand and caused the fire to brake out.

Although 2017 has been a great year, SpaceX has suffered two catastrophic rocket accidents in 2015 and 2016 as a result of unrelated failures traced to the second stage which slowed down the launch pace as engineers raced to identify and rectify the root causes.

Engineers were conducting a pre-test operation when the test bay fire broke out. It may take a few weeks or more to repair the test stand and resume hot fire testing.

SpaceX has notified customers such as NASA, the FAA and the USAF about the incident – for which SpaceX plans a Dragon cargo resupply mission to the ISS launching as soon as Dec. 4 from Cape Canaveral Air Force Station, FL.

“We are now conducting a thorough and fully transparent investigation of the root cause.”

Fortunately there were no injuries to any personal.

“No one was injured and all safety protocols were followed during the time of this incident,” Taylor explained.

The Merlin engine about to be tested involved the most advanced type known as the Block 5 version that will be used to propel astronauts to orbit inside the SpaceX Crew Dragon.

The Falcon 9 is currently powered by 9 Merlin 1D engines of the Block 4 version.

Altogether they generate a combined 1.7 million pounds of liftoff thrust.

SpaceX can continue launches with the less advanced Merlin 1D version because testing of Block 4 is still happening.

KENNEDY SPACE CENTER, FL – SpaceX delivered a spectacular Halloween eve delight with today’s Falcon 9 launch of a Korean HDTV satellite that lit up the Florida Space Coast skies with a glow that delighted kids of all ages and ghouls alike and put an end at last for today to the atrocious wet and windy weather afflicting the Spaceport region.

The SpaceX Falcon 9 blasted off mid-afternoon Monday Oct. 30 with the private KoreaSat-5A telecomsat mission right at the opening of the launch window at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Eight and a half minutes after liftoff the 15 story tall first stage booster nailed another rocket assisted touchdown on the OCISLY droneship pre-positioned several hundred miles off shore of Cape Canaveral in the Atlantic Ocean.

Today’s mission marks the 16th launch by SpaceX this year, the 2nd this month by the new space firms Falcon 9 rocket from Florida’s Spaceport, and the third overall counting another liftoff from Vandenberg AFB, Calif. – thus maintaining an absolutely torrid and record setting yearly launch pace.

The launch was broadcast live on a SpaceX dedicated webcast.

Florida finally fulfilled its billing as the ‘Sunshine State’ with truly superb afternoon weather for Monday afternoon’s liftoff of a SpaceX Falcon 9 with its first Korean satellite customer – and the decent weather outlook looks like it will extend into Tuesdays Halloween trick or treating for the local kiddies and their imaginative costumes.

The two stage 229-foot-tall (70-meter-tall) Falcon 9 rocket shined at sunrise this morning and throughout the countdown and fueling process fed the falcon with RP-1 and liquid oxygen propellant powering the rockets nine first stage Merlin 1D engines.

Altogether the Merlin 1D engine delivered a powerful liftoff punch that was far more than a Halloween ‘boo’ as the engines ignited with 1.7 million pounds of liftoff thrust.

As the Falcon 9 roared off launch pad 39A a rumbling thunder reverberated across the space coast region and beyond that brought broad smiles of glee to spectators faces packing local area beaches and hotels and quickly dispatched wicked ghouls to their graves.

Trick or treaters will have a fine Halloween indeed following SpaceX’s thunderous rocket launch into picture perfect clear blue skies that were set of fire as the rocket vaulted off the pad and arched over eastwards to the African continent as it accelerated to the heavens.

The SpaceX Falcon 9 successfully delivered Koreasat-5A to a geostationary transfer orbit (GTO).

Satellite deployment took place as planned 35 minutes after launch as seen on the webcast.

“Successful deployment of Koreasat-5A to geostationary transfer orbit confirmed,” said SpaceX.

The launch was also accompanied by a successful attempt to recover the 156 foot tall first stage booster after completing its primary satellite delivery mission task.

Choppy seas from Tropical Storm Phillipe made the sea landing even more challenging.

SpaceX engineers guided it to a landing on the tiny OCISLY drone ship for an upright and intact pinpoint soft landing touchdown on the ocean going platform prepositioned off shore in the Atlantic Ocean – some 8 minutes after blastoff.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 30 launch and was prepositioned in the Atlantic Ocean several hundred miles (km) off the US East coast, awaiting the boosters approach and pinpoint propulsive soft landing.

“Falcon 9 first stage has landed on the Of Course I Still Love You droneship.” announced SpaceX.

“A little toasty, but stage one is certainly still intact on the droneship.”

A small fire broke out on the Falcon 9 atop the droneship after landing as seen on the webcast but it was quickly extinguished.

The nearly two ton commercial KoreaSat-5A satellite will provide Direct to Home (DTH) broadcasting, maritime, internet and other services to the Asian region centering around South Korea.

It has a 15 year design lifetime.

KoreaSat-5A was built by Thales Alenia Space and launched by SpaceX under a commercial contract for South Korean operator KTSAT (a KT Corporation company) using a freshly built first stage booster.

KTSAT is South Koreas sole satellite service provider.

Of course North Koreans have no access to any of these services as they are forbidden under the regime of Kim Jong Un with severe penalties for any violators.

The satellite was attached to the booster encapsulated in the nose cone last Friday after engineers successfully completed the routine but required static hot fire test of the first stage engines last Thursday, Oct 26.

Koreasat-5A was built by prime contractor, Thales Alenia Space, responsible for the design, production, testing and ground delivery. It arrived at the Florida launch base on Oct. 5 for integration with the Falcon 9 rocket.

The 3,700 kg (8,160 lb) satellite is equipped with 36 Ku-band transponders and based on Thales Alenia Space’s new-generation Spacebus 4000B2 platform. It will replace Koreasat 5 launched a decade ago in 2006.

The solar panels provide a payload power of approximately 6.5 kW. It will be positioned at 113° East and provide coverage for Indochina, Japan, Korea, the Philippines and the Middle East including Direct to Home (DTH) services.

Pad 39A has been repurposed by SpaceX from its days as a NASA shuttle launch pad.

To date SpaceX has now accomplished 19 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

The KoreaSat-5A booster is expected back into Port Canaveral later this week – and the public can watch the sailing action.

CAPE CANAVERAL AIR FORCE STATION, Fla. – Thursday’s (May 26) planned blastoff of an upgraded SpaceX Falcon 9 rocket on a lucrative commercial mission to deliver a Thai telecommunications satellite to orbit, was postponed in the final stages of the countdown after engineers discovered a technical glitch in the booster’s second stage.

Liftoff of the two stage Falcon 9 is now planned for Friday, May 27 at 5:39 p.m. EDT from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida.

Soon after liftoff, SpaceX will again execute a sea landing attempt of the first stage booster on a platform a sea following a tough reentry trajectory.

Since the launch window extends two hours, the SpaceX launch team took the time available to work the issue and tried as best they could to resolve it.

But in the end, and more than an hour into the available window, launch controllers decided it was best to stay safe and scrub for the day at about 6:40 p.m. EST and take the opportunity to thoroughly review all the data.

“Out of an abundance of caution, launch postponed until no earlier than tomorrow [May 27] for additional data review” SpaceX said via social media accounts.

Hundreds of millions of dollars are at stake on this commercial flight slated to deliver the Thaicom-8 comsat to a Geostationary Transfer Orbit (GTO) for Thaicom PLC, a leading satellite operator in Asia.

“Falcon 9 & THAICOM 8 spacecraft remain healthy,” SpaceX tweeted.

SpaceX founder and CEO Elon Mush said that the problem was traced to an engine actuator in the second stage wich is critical for delivering Thaicom-8 to its required geostationary orbit.

“There was a tiny glitch in the motion of an upper stage engine actuator,” SpaceX CEO Musk tweeted.

“Probably not a flight risk, but still worth investigating.”

You can watch the launch live on Friday via a special live webcast from SpaceX.

The SpaceX webcast will be available starting at about 20 minutes before liftoff, at approximately 5:19 p.m. EDT- at SpaceX.com/webcast
The two stage Falcon 9 rocket has a two-hour launch window that extends until Friday, May 27 at 7:39 p.m. EDT.

The Florida weather is much less favorable than yesterday. Air Force meteorologists are predicting only a 40 percent chance of favorable weather conditions at launch time Friday. The major concerns could be violations of the Thick Cloud Layer Rule, Cumulus Cloud Rule, and Liftoff Winds.
