KENNEDY SPACE CENTER, FL – After seemingly endless bouts of damaging rain squalls and flooding, Florida is at last living up to its billing as the ‘Sunshine State’ with some superb weather forecast for Monday afternoon’s scheduled liftoff of a SpaceX Falcon 9 with its first Korean customer – on the eve of Halloween.

SpaceX engineers are targeting the Falcon 9 for a mid-afternoon liftoff with the private KoreaSat-5A telecomsat mission for a window that opens at 3:34 p.m. EDT (1934 GMT) Monday Oct. 30 from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The two stage 229-foot-tall (70-meter-tall) Falcon 9 rocket was raised to vertical launch position later Sunday afternoon.

The launch will also be accompanied by an attempt to recover the first stage booster by soft landing on an ocean going platform prepositioned off shore in the Atlantic Ocean – some 8 minutes after blastoff.

If all goes well, SpaceX will conduct their 16th launch this year and the 2nd this month by the new space firms Falcon 9 rocket from Florida’s Spaceport – maintaining an absolutely torrid and record setting yearly launch pace.

Space enthusiasts and Halloween trick or treaters alike will surely enjoy the heavenly fireworks display. And to top that off the procedure to recover the rockets first stage has been described as riding a ‘witches broom’ in the middle of a hurricane since the 15 story tall stick has to flip around and fire its engines while traveling at several thousand miles per hour to place it on course for the droneship.

The KoreaSat liftoff will also count as October’s third from the increasingly busy Florida Space Coast capping two earlier missions carried out by both ULA and SpaceX.

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

The satellite was attached to the booster encapsulated in the nose cone over the weekend after engineers successfully completed the static hot fire test of the first stage engines on Thursday, Oct 26.

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.

You can watch the launch live on a SpaceX dedicated webcast starting about 10 minutes prior to the 3:34 p.m. EDT (1934 GMT) liftoff time.

The launch window for the newly built booster extends nearly two and a half hours until it closes at 5:58 p.m. EDT (2158 GMT).

The weather outlook is uncommonly excellent along the Florida Space Coast with a greater than 90% chance of favorable conditions at launch time according to U.S. Air Force meteorologists with the 45th Space Wing Weather Squadron at Patrick Air Force Base.

The primary concerns on Oct. 30 are only for Liftoff Winds.

The odds remain high at 90% favorable for the 24 hour scrub turnaround day on Halloween Day, Tuesday Oct. 31.

Tropical Storm Philippe is not an issue and has moved north of the Bahamas and will continue moving northeastward at 30 mile per hour today says the AF.

Temperatures will be cool however on Monday dipping into the 50s and 60s.

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

After the 156 foot tall first stage booster completes its primary mission task, SpaceX engineers seek to guide it to a second landing on the tiny OCISLY drone ship for a soft touchdown some eight and a half minutes after liftoff.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 30 launch and may be prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast, just waiting for the boosters approach and pinpoint propulsive soft landing.

The path to an October launch trifecta from Florida’s Spaceport was cleared following SpaceX’s successful static fire test of the Falcon 9 boosters first stage engines this past Thursday afternoon, 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 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.

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.

KENNEDY SPACE CENTER, FL – Amidst the frenzy of ‘Sunshine State’ preparations for Cat 5 monster Hurricane Irma and quite dismal weather favorability odds, the skies surrounding the Florida Space Coast suddenly parted just in the nick of time enabling the Air Force’s secret military X-37B spaceplane to blast off this morning (Sept. 7) on a SpaceX Falcon 9 as the booster nailed another thrilling ground landing back at the Cape.

The SpaceX Falcon 9 roared to life at 10 a.m. EDT (1400 UTC) Thursday morning and soared aloft from seaside Launch Complex 39A on NASA’s Kennedy Space Center into nearly clear blue skies after the classified launch time was kept guarded until just 10 minutes before liftoff.

Due to the potential for catastrophic destruction from approaching Hurricane Irma this was the last chance for the X-37B to escape Florida to orbit before the Kennedy Space Center and Cape Canaveral Air Force Station almost certainly close on Friday, the backup launch opportunity.

The X-37B OTV spaceplane reached orbit as planned on SpaceX’s 13th launch of the year.

“The 45th Space Wing successfully launched a SpaceX Falcon 9 launch vehicle Sept. 7, 2017, from Kennedy Space Center’s Launch Complex 39A,” the USAF and 45th Space Wing confirmed in a post launch statement.

The Falcon 9 launch was absolutely gorgeous taking place under near perfect weather conditions at launch time and putting on a long sky show as the rocket accelerated to orbit with its precious cargo.

The nine Merlin 1D first stage engines ignited to generate a combined 1.7 million pounds of thrust fueled by liquid oxygen and RP-1 propellants, sending a huge exhaust plume billowing from behind as the rocket ascended off pad 39A and thundered aloft.

After first stage burnout and main engine cutoff the stages separated at T plus 2 min 26 seconds.

After successfully delivering the secret USAF mini-shuttle to orbit, SpaceX engineers completed the 2nd half of the double headed space spectacular when the Falcon 9 first stage booster successfully made a guided soft landing back at Cape Canaveral Air Force Station (CCAFS).

The boosters high speed descent generated multiple shockingly loud sonic booms as the 156-foot-tall first stage approached SpaceX’s dedicated Landing Zone-1 (LZ-1) on CCAFS that reverberated for dozens and dozens of miles across and beyond the Space coast region.

The mid-morning daylight first stage precision guided landing offered spectators a magnificent up close view of the rocket reusability technology envisioned by SpaceX’s billionaire CEO Elon Musk to drastically slash the high costs of launching people and payloads to space.

The X-37B reusable mini-shuttle is a secretive technology testing spaceplane flying on its fifth mission overall for the U.S. Air Force Rapid Capabilities Office.

“The OTV is designed to demonstrate reusable spacecraft technologies for America’s future in space and operate experiments, which can be returned to and examined on Earth,” said the USAF.

Also known as the Orbital Test Vehicle, the X-37B launched on the OTV-5 mission marks the programs maiden liftoff on the 230-foot-tall SpaceX Falcon 9.

All four prior OTV missions launched on the United Launch Alliance Atlas V and ended with runway landings in either California of Florida.

The X-37B launches vertically like a satellite but lands horizontally like an airplane and functions as a reliable and reusable space test platform for the U.S. Air Force.

The Boeing-built X-37B is processed for flight at the Kennedy Space Center, FL, using refurbished former NASA space shuttle processing facilities (OPFs) now dedicated to the reusable mini-shuttle, also named the Orbital Test Vehicle (OTV).

The last blastoff of the X-37B took place more than 2 years ago on May 20, 2015 when the OTV-4 mission launched on a ULA Atlas V on May 20, 2015 from Space Launch Complex-41 on Cape Canaveral Air Force Station.

After spending a record setting 718 days in orbit, the X-37B vehicle completed its fourth mission with a runway landing back at KSC’s Shuttle Landing Facility earlier this year on May 7, 2017.

Overall the OTV unmanned spacecraft have spent a total of 2,085 days in orbit.

The 11,000 pound (4990 kg) state-of-the art reusable OTV space plane is about a quarter the size of a NASA space shuttle. The vehicle measures 29 ft 3 in (8.9 m) in length with a wingspan of 14 ft 11 in (4.5 m).

The X-37B was originally developed by NASA but was transferred to the Defense Advanced Research Projects Agency (DARPA) in 2004.

Since then most but not all of the spaceplane’s goals have been shrouded in secrecy.

PLAYALINDA BEACH/KENNEDY SPACE CENTER, FL – Following a successful engine test firing of the Falcon 9 first stage late Thursday afternoon (Aug. 30), SpaceX is targeting a post Labor Day launch of the U.S. Air Force’s unmanned X-37B reusable mini-shuttle – a secretive technology testing spaceplane.

The brief but critical hold down engine test took place at 4:30 p.m. EDT (2030 GMT) Aug. 31 at Launch Complex 39A on NASA’s Kennedy Space Center – as witnessed live by myself and several spectators from nearby Playalinda Beach Causeway. See my photos herein.

Both SpaceX and the Air Force announced the target launch date after completion of the Aug. 31 engine test.

“Static fire test complete,” SpaceX confirmed via Twitter soon after completion of the test, “—targeting Falcon 9 launch of OTV-5 from Pad 39A at @NASAKennedy on Thursday, September 7.”

The routinely done static fire test and involves conducting a full launch dress rehearsal and countdown culminating with igniting all nine Merlin 1D first stage engines during a hold down test at the pad.

The Merlin’s generated a combined 1.7 million pounds of thrust and a huge exhaust plume billowing into the air from the north side flame trench during the test, which lasted several seconds.

The plume soon swirled overhead and dissipated about 10 minutes later. Ignition was accompanied by a loud roar we heard screaming out from the pad in all directions. A number of folks driving to and from Playalinda Beach had stopped to ask me what I was photographing prior to the test and stayed to witness the event.

The rocket will be lowered rolled back horizontally on the transporter erector into the SpaceX processing hangar and the spaceplane housed inside the payload fairing will be integrated on top. The full stack will then be rolled back out and erected at pad 39A.

The hold down test firing is carried out without the payload bolted on top inside the nose cone to keep it safe in the event of a catastrophic failure event such as occurred precisely 1 year ago – when a Falcon 9 blew up during fueling for similar engine test with the AMOS-6 satellite resulting in destruction of the rocket as well as the customers satellite hardware at pad 40.

The exact launch time had been a closely guarded secret – until this evening.

The X-37B launch is apparently lunchtime Thursday, September 7 at 12 PM – 12:01 PM, according to a Facebook post by the U.S. Air Force Space Command and the 45th Space Wing at Patrick Air Force Base, Fla., posted Friday evening.

“The Air Force Rapid Capabilities Office is undergoing final launch preparations for the fifth mission of the X-37B Orbital Test Vehicle [OTV],” the Secretary of the Air Force Public Affairs announced. “The OTV is scheduled to launch on Sept. 7, 2017, onboard a SpaceX Falcon 9 launch vehicle.

The X-37B will be launched for the fifth time on the OTV-5 mission atop a SpaceX Falcon 9 on Sept. 7 from Launch Complex 39A on the Kennedy Space Center Florida into low Earth orbit.

The Boeing-built X-37B is processed for flight at KSC using refurbished NASA space shuttle processing facilities now dedicated to the reusable mini-shuttle, also known as the Orbital Test Vehicle (OTV). It launches vertically like a satellite but lands horizontally like an airplane and functions as a reliable and reusable space test platform for the U.S. Air Force.

But in another first, the OTV-5 mission marks the first launch of an X-37B spaceplane by SpaceX.

All four prior OTV missions launched on the United Launch Alliance Atlas V and ended with runway landings in either California of Florida.

“The many firsts on this mission make the upcoming OTV launch a milestone for the program,” said Randy Walden, the director of the Air Force Rapid Capabilities Office.

“It is our goal to continue advancing the X-37B OTV so it can more fully support the growing space community.”

The OTV-4 mission launched on the ULA Atlas V on May 20, 2015 from Space Launch Complex-41, on Cape Canaveral Air Force Station.

Playalinda Beach is located just 4 miles north of pad 39A and offers an excellent launch viewing location for the OTV-5 mission – if officials allow it to be open to the public.

The engine test comes at the end of a very busy August with a trio of Florida Space Coast launches plus a Total Solar ‘Eclipse Across America’ sandwiched in between.

Also noteworthy is that OTV-5 will be launched into a higher inclination orbit compared to the prior four, serve as a technology testbed for multiple research payloads and will also somehow deploy several small satellites or cubesats.

“The fifth OTV mission continues to advance the X-37B’s performance and flexibility as a space technology demonstrator and host platform for experimental payloads,” the USAF said in a statement.

“This mission carries small satellite ride shares and will demonstrate greater opportunities for rapid space access and on-orbit testing of emerging space technologies. Building upon the fourth mission and previous collaboration with experiment partners, this mission will host the Air Force Research Laboratory Advanced Structurally Embedded Thermal Spreader payload to test experimental electronics and oscillating heat pipe technologies in the long duration space environment.”

SpaceX will also attempt another land landing of the 156-foot-tall Falcon 9 first stage back at Landing Zone-1 (LZ-1) at the Cape.

The Falcon 9 first stage is equipped with a quartet of landing legs and grid fins to enable the rocket recycling plan.

“The fifth OTV mission will also be launched into, and landed from, a higher inclination orbit than prior missions to further expand the X-37B’s orbital envelope.”

The daylight first stage precision guided landing should offer spectators a thrilling up close view of the rocket reusability technology envisioned by SpaceX’s billionaire CEO Elon Musk to drastically slash the high costs of launching to space.

KENNEDY SPACE CENTER, FL – Spectacular 4th of July fireworks are coming tonight, July 3,[reset to July5] to the Florida Space Coast courtesy of SpaceX and Intelsat with the planned near dusk launch of the commercial Epic 35e next-generation high throughput satellite to geostationary orbit for copious customers in the Americas, Europe and Africa. UPDATE: After a 2nd abort launch is now NET July 5.

JULY 5 UPDATE: GO for launch attempt tonight at 7:37 PM. Weather looks good at this time.

“SpaceX, confirms that we are ‘Go’ for a launch tonight, 5 July, at approximately 23:37:00 UTC (7:37pm EDT), GO INTELSAT 35E!!” Intelsat announced.

If all goes well, SpaceX will have demonstrated an amazing launch pace with 3 rockets propelled aloft in the span of just 10 days from both US coasts.

Originally slated for Sunday evening, July 2, the launch was automatically aborted by the computer control systems literally in the final moments before the scheduled liftoff due to a guidance issue, and under picture perfect weather conditions – which would have resulted in 3 launches in 9 days.

Following the 24 hour scrub turnaround, blastoff of the Intelsat 35e communications satellite for commercial broadband provider Intelsat is now slated for dinnertime early Monday evening, July 3 at 7:37 p.m. EDT, or 2337 UTC from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

The first stage will not be recovered for this launch because the massive 6800 kg Intelsat 35e comsat requires every drop of fuel to get to the desired orbit.

“There will be no return of the booster for this mission, “ Ken Lee, Intelsat’s senior vice president of space systems, told Universe Today in a prelaunch interview on Sunday.

“We [Intelsat] need all the fuel to get to orbit.”

By using all available fuel on board the Falcon 9, Intelsat 35e will be delivered to a higher orbit.

“This will enable us to use less fuel for orbit raising maneuvers and make more available for station keeping maneuvers,” Lee told me.

“We hope this will potentially extend the satellites lifetime by 1 or 2 years.”

“Intelsat 35e is the fourth in the series of our ‘Epic’ satellites. It will provide the most advanced digital services ever and a global footprint.”

You can watch the launch live on a SpaceX dedicated webcast starting about 15 minutes prior to the opening of the launch window at 7:37 p.m. EDT, or 2337 UTC

“Our whole team had to activate quickly to get Intelsat 35e into this window and ready for launch. The good news is we partnered with SpaceX and Boeing, the satellite builder,” said Kurt Riegel Sr VP Intelsat Sales & Markenting, in an interview with Universe Today at the countdown clock at the KSC Press Site.

There was barely a week to turn around the Falcon 9 rocket and launch pad sinevc the blastoff of BulgariaSat-1.

“Boeing got everything accomplished on time and not give an inch on our test schedule or our quality which is so important to us.”

Monday’s [now Wednesday July] weather forecast is currently 70% GO for favorable conditions at launch time.

The weather odds have changed dramatically all week – trending more favorable.

The concern is for the Cumulus Cumulus Cloud Rule according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base.

Monday’s abort took place 10 seconds before liftoff but was called at T-Zero by the SpaceX launch director. A problem was detected with the GNC system, which stands for guidance, navigation and control.

“We had a vehicle abort criteria violated at T-minus 10 seconds, a GNC criteria,” the launch director announced on the SpaceX webcast soon after the abort was called.

“We’re still looking into what that is at this time.

He then announced a scrub for the day.

“We’re not going to be able to get a recycle in today without going past the end of the window, so we’re officially scrubbed,” he stated on the webcast.

“Go ahead and put a 24-hour recycle into work.”

KENNEDY SPACE CENTER, FL – Following SpaceX’s “exceptional performance” launching an immensely powerful broadband satellite on their maiden mission for Inmarsat this week on a Falcon 9 rocket, the company CEO told Universe Today that Inmarsat was willing to conduct future launches with SpaceX – including on a “reusable rocket in the future!”

“This has obviously been an absolutely exceptional performance from SpaceX, Inmarsat CEO Rupert Pearce told Universe Today in a post launch interview at the Kennedy Space Center on Monday, May 15.

“They have now earned themselves an immensely loyal customer.”

SpaceX is the first and thus far only company in history to successfully recover and refly a previously flown orbit class ‘flight-proven’ liquid fueled first stage rocket – during the SES-10 launch in March 2017.

The twilight blastoff of the SpaceX Falcon 9 carrying the Inmarsat-5 Flight 4 communications satellite for commercial High-Speed mobile broadband provider Inmarsat occurred at 7:21 p.m. EDT (or 23:21 UTC) on Monday evening, May 15, from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

“They hit the ball out of the park with this launch for us,” Inmarsat CEO Pearce told me regarding the new space company founded by billionaire CEO Elon Musk.

The never before used 229-foot-tall (70-meter) SpaceX Falcon 9 successfully delivered the gigantic bus sized 6100 kg Inmarsat-5 F4 satellite to a Geostationary Transfer Orbit (GTO) under brilliant blue and nearly cloudless twilight skies from the Florida Space Coast. Read my launch report here.

The first stage is powered by nine Merlin 1 D engines fueled by RP-1 and liquid oxygen propellants and generating 1.7 million pounds.

The Inmarsat-5 F4 satellite is designed to provide high speed broad band service to government, military, maritime and aviation users and ship and airplane customers numbering in the millions to tens of millions of customers now and potentially hundreds of millions of customers in the future. It was the heaviest payload ever launched by a Falcon 9.

Pearce says he “has every confidence in SpaceX.”

Inmarsat is a leading provider of mobile satellite communications, providing global connectivity more than 35 years – on land, at sea and in the air, says the firm.

I asked CEO Pearce; What does the future hold regarding further Inmarsat launches with SpaceX?

“They [SpaceX] have now just gained and earned themselves an immensely loyal customer [from Inmarsat], CEO Pearce replied.

“We will be looking to do further launches with them.”

The 7 meter long Inmarsat-5 F4 satellite was deployed approximately 32 minutes after Monday’s launch when it will come under the command of the Boeing and Inmarsat satellite operations teams based at the Boeing facility in El Segundo.

Would you consider a used rocket, a previously flown booster?

“I’m sure we will be using a ‘reused rocket’, Pearce stated. “And we will be launching on a ‘reusable rocket’ in the future.”

“We will be looking to support them in any way we can with their new innovation programs.”

In contrast to virtually all Falcon 9 launches in the past 18 months, no attempt was made to recover the first stage booster.

For this launch there was basically no choice but to make the first stage ‘expendable’ because Inmarsat-5 F4 is heaviest ever payload launched on a Falcon 9.

The satellites heavy weight with a launch mass of approx. 6,100 kg (13,400 lbs) means the rocket needs all its thrust to get the satellite to orbit and thus precludes the chance to land the first stage at sea or land.

Thus there are no landing legs or grid gins attached to the skin of this Falcon 9.

“This rocket that went today was not reusable. That was just a creature of its time,” Pearce elaborated.

“We will stay at the cutting edge with SpaceX!”

To date, SpaceX has successfully recovered 10 first stage boosters either by land or by sea on an ocean going platform.

The Inmarsat-5 F4 (I-5 F4) will become part of the firms Global Xpress network “which has been delivering seamless, high-speed broadband connectivity across the world since December 2015,” says Inmarsat.

“Once in geostationary orbit, the satellite will provide additional capacity for Global Xpress users on land, at sea and in the air.”

I-5 F4 was built by Boeing at their satellite operations facility in El Segundo, CA for Inmarsat.

The new satellite will join 3 others already in orbit.

Inmarsat has invested approximately US$1.6 billion in the Global Xpress constellation “to establish the first ever global Ka-band service from a single network operator.”

Inmarsat 5 F4 counts as the sixth SpaceX launch of 2017.

And SpaceX is on an absolutely torrid launch pace. Monday’s liftoff comes just 2 weeks after the last successful SpaceX Falcon 9 liftoff on May 1 of the super secret NROL-76 payload for the National Reconnaissance Office, or NRO – as I reported here.

MERRITT ISLAND NATIONAL WILDLIFE REFUGE, FL – Elon Musk’s SpaceX is primed for another significant space first; the firms first launch of a spy satellite for the US governments super secret spy agency; the National Reconnaissance Office, or NRO – following today’s successful static hotfire test of the Falcon 9 launchers first stage booster.

Tuesday’s hotfire test to took place shortly after 3 p.m. this afternoon, April 25, at SpaceX’s seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The successful test paves the path for launch of the NROL-76 classified payload for the NRO atop a SpaceX Falcon 9 rocket this Sunday morning, April 30 from pad 39A.

“Static fire test complete,” SpaceX confirmed via social media just minutes after finishing the brief test at 3:02 p.m. EDT (1902 GMT).

“Targeting Falcon 9 launch of NROL-76 on Sunday, April 30.”

The engine test is conducted using only the first two stages of the rocket – minus the expensive payload in case anything goes wrong as like occurred during the catastrophic AMOS-6 static fire disaster last September.

The test is routinely done so that SpaceX engineers can confirm the readiness of the rocket and all its systems to safely and successfully launch the specified payload to its intended orbit.

Furthermore this launch is also notable because it features the next land landing by a SpaceX Falcon 9 first booster back at the Cape for only the fourth time in history – which also makes for an extremely thrilling experience – and unforgettable space enthusiasts event.

So by all means try to witness this launch from the Florida Space Coast in person, if at all possible.

The breakfast time launch window on Sunday, April 30 opens at 7 a.m. EDT. It extends for two hours until 9.a.m. EDT.

The long range weather outlook currently looks favorable with lots of sun and little rain. But that can change on a moment’s notice in the sunshine state.

The brief engine test lasting approximately three seconds took place at 3:02 p.m. today, Tuesday, April 25, with the sudden eruption of smoke and ash rushing out the flame trench to the north and into the air over historic pad 39A on NASA’s Kennedy Space Center during a picture perfect sunny afternoon – as I witnessed from the Merritt Island National Wildlife Refuge in Titusville, FL.

During today’s static fire test, the rocket’s first and second stages are fueled with densified liquid oxygen and RP-1 propellants like an actual launch, and a simulated countdown is carried out to the point of a brief engine ignition with the rocket firmly clamped down and held in place.

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 while the two stage rocket was restrained on the pad.

This is only the fourth Falcon 9 static fire test ever conducted on Pad 39A.

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

Watch this video of the April 25 static fire test from colleague Jeff Seibert:

Following the engine test, the propellants are drained and the rocket is rolled off the pad and back into the huge SpaceX processing hanger at the pad perimeter.

The NROL-76 classified surveillance satellite will be bolted on top. The rocket will be rolled back to pad 39A in advance of Sunday’s planned blastoff.

PORT CANAVERAL/KENNEDY SPACE CENTER, FL – Basking in the sunrise glow, the world’s first recycled booster – namely a SpaceX Falcon 9 – sailed serenely into Port Canaveral this morning, Tuesday, April 4, atop the tiny droneship on which it soft landed shortly after launching on March 30 for an unprecedented second time.

Shortly before sunrise, SpaceX’s recovered Falcon 9 first stage triumphantly arrived on Tuesday at the mouth of Port Canaveral and the public pier at Jetty Park around 7 am – greeted by excited onlookers, media and space buffs eager to be an eyewitness to the first rocket to launch and land two times fully intact !

The Falcon 9 standing proudly erect on the football field sized OCISLY droneship landing pad was towed into port by the Elsbeth III in the wee morning hours around 7 am. The ships made their way majestically along the channel westwards until reaching the docking port.

The milestone SpaceX mission to refly the first ever ‘used rocket’ blasted off right on time at the opening of the dinnertime launch window on Thursday, March 30, at 6:27 p.m. EDT.

The used two stage 229-foot-tall (70-meter) rocket carried the SES-10 telecommunications payload to orbit using a ‘Flight-Proven’ Falcon 9 rocket from seaside Launch Complex 39A at NASA’s Kennedy Space Center (KSC) in Florida.

After the 156 foot tall first stage booster completed its primary mission task, SpaceX engineers successfully guided it to a second landing on the tiny Of Course I Still Love You – OCISLY – drone ship for a soft touchdown some eight and a half minutes after liftoff.

“This is a huge revolution in spaceflight,” billionaire SpaceX CEO and Chief Designer Elon Musk told reporters at the post launch briefing at the Kennedy Space Center press site, barely an hour after liftoff.

Musk’s goal is to drastically reduce the cost of spaceflight so that it will one day lead to a ‘City on Mars’.

OCISLY had left Port Canaveral several days ahead of the March 30 launch and was prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast, just waiting for the boosters 2nd history making approach and pinpoint propulsive soft landing.

This recycled Falcon 9 first stage booster had initially launched a year ago in April 2016 for NASA on the SpaceX Dragon CRS-8 resupply mission to the International Space Station (ISS) under contract for the space agency.

After making its way picturesquely through Port Canaveral channel, the droneship was docked, Workers soon attached a metal cap to the top of the first stage.

Next they removed the restraining chains fastening the booster to the deck. Next they hoisted it off the droneship with a work crane and transported it onto a work pedestal on the ground for further processing.

By late evening I observed that the workers were still busily operating on the booster. They were welding the metal cap to the top of the booster. All 4 landing legs were still attached as of 10 p.m. EDT on Tuesday, April 4.

The legs will soon be detached so the booster can be rotated horizontal and trucked back to the huge hangar at pad 39A.

KENNEDY SPACE CENTER, FL – The moment of truth is rapidly approaching as SpaceX attempts the world’s first reflight of an orbital class rocket later today, Thursday, March 30, with the firms Falcon 9 standing proudly at historic launch complex 39A at NASA’s Kennedy Space Center in Florida – ready to deliver an advanced TV broadcast satellite to orbit for the America’s for telecom giant SES.

If successful, the launch will mightily advance billionaire SpaceX CEO Elon Musk’s bold vision to slash launch costs by recovering and reusing spent first stage rockets from his firms Falcon 9 launch vehicle.

“The SES-10 mission will mark a historic milestone on the road to full and rapid reusability,” say Space officials.

“We are confident in this booster,” SES CTO Martin Halliwell told Universe Today at a press briefing on March 28.

The milestone SpaceX mission destined to refly the first ever ‘used rocket’ is slated for lift off on Thursday, March 30, at 6:27 p.m. EDT carrying the SES-10 telecommunications payload to orbit atop a ‘Flight-Proven’ Falcon 9 rocket from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

So, if you want to witness this truly magnificent event in space history with your own eyes, there’s only a few hours left for you to ‘Get Your Ass to KSC!’ to paraphrase Apollo 11 moonwalker Buzz Aldrin.

The nearly six ton SES-10 satellite will provide significantly improved TV, voice, data and maratime service to over 37 million customers across Central and South America.

Eventually, Musk hopes to help establish a ‘City on Mars’ by building Interplanetary Colonial Transporters to transport human settlers to live on the Red Planet – the most Earth-like world in our Solar System.

You can watch the launch live on a SpaceX dedicated webcast starting about 20 minutes prior to the 6:27 pm EDT or 10:27 pm UTC liftoff time.

The two and a half hour launch window closes at 9:57 p.m. EDT.

The weather outlook is glorious along the Florida Space Coast with an 80% chance of favorable conditions at launch time in the latest AF prognosis.

However for the back-up launch date on Friday, the outlook worsens considerable to only 40% favorable.

“This thing is good to go!” Halliwell told me.

The Falcon 9 booster to be recycled was initially launched in April 2016 for NASA on the SpaceX Dragon CRS-8 resupply mission to the International Space Station (ISS) under contract for the space agency.

The 156 foot tall first stage was recovered about eight and a half minutes after liftoff via a pinpoint propulsive soft landing on an tiny ocean going droneship prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast.

If all goes well SpaceX will also attempt to re-land the Falcon 9 first stage on an oceangoing barge for an unprecedented second time, provided there are sufficient fuel reserves remaining after accomplishing its primary mission of delivering SES-10 to GTO, Halliwell stated.

The SES-10 launch comes barely 2 weeks after the prior SpaceX launch of EchoStar XXIII on March 16.

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.”

The flight proven SpaceX Falcon 9 rocket will deliver SES-10 to a Geostationary Transfer Orbit (GTO).

SES-10 has a launch mass of 5,300 kg or 11,700 pounds, which includes the dry mass and propellant.

The spacecraft utilizes for both chemical propulsion for orbit raising and electric propulsion for station keeping.

SES-10 will replace AMC-3 and AMC-4 to provide enhanced coverage and significant capacity expansion over Latin America, says SES.

“The satellite will be positioned at 67 degrees West, pursuant to an agreement with the Andean Community (Bolivia, Colombia, Ecuador and Peru), and will be used for the Simón Bolivar 2 satellite network.”

Up to 3 additional SES satellites could launch on SpaceX Falcon 9 rockets by the end of this year.

KENNEDY SPACE CENTER, FL – SpaceX’s tenth contracted resupply mission to the International Space Station came to a safe conclusion with a splashdown of the Dragon spacecraft in the Pacific Ocean Sunday and successfully returned a treasure trove of more than two tons of precious science experiments and research samples from the space station.

Researchers on Earth are eagerly awaiting the science data and samples in order to carry out high powered laboratory analysis that will eventually yield the fruits of the hard won labor – years in the making.

The Dragon CRS-10 cargo freighter departed the International Space Station (ISS) Sunday morning after Expedition 50 astronauts Thomas Pesquet of ESA (European Space Agency) and Shane Kimbrough of NASA released the spacecraft from the grip of the station’s 57.7-foot-long(17.6-meter) Canadian-built Canadarm2 robotic arm as planned at 5:11 a.m. EDT, March 19.

After carefully maneuvering away from the orbiting outpost and six person international crew at an altitude of appox. 250 miles (400 km), Dragon eased away to a safe distance.

The vessel then fired its braking thrusters a few hours later to initiate the reentry burn that would set the craft on course for a fiery plummet through the Earth’s atmosphere.

Some five and a half hours later the spaceship carried out a parachute assisted splashdown in the Pacific Ocean at 10:46 a.m. EDT, about 200 miles southwest of Long Beach, California.

The highest priority research and technology cargo will be removed from Dragon immediately and returned to NASA.

The rest will travel back to port and be prepared for a return trip to SpaceX’s test facility in McGregor, Texas, where the remaining scientific samples, research experiments and technology gear and hardware will be unloaded for NASA.

Dragon had spent nearly a month berthed at the Earth-facing port on the station’s Harmony module, since arriving on Feb 23.

Dragon begun its space voyage after it was launched from the Kennedy Space Center (KSC) on Sunday, Feb. 19 on the first Falcon 9 rocket ever to blast off from historic launch pad 39A in a blaze of glory – as I reported here.

At liftoff, the Dragon CRS-10 space freighter was 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 to the low Earth orbiting station in support of the Expedition 50 and 51 crew members.

After a four day chase, Dragon was captured and attached to the station using the Canadian arm on Feb 23 by the same two astronauts who released it on Sunday.

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.

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. It is one of NASA’s longest running earth science programs.

The LIS lightning mapper will measure the amount, rate and energy of lightning as it strikes around the world from the altitude of the ISS as it orbits Earth. Its data will complement that from the recently orbited GLM lighting mapper lofted to geosynchronous aboard the NASA/NOAA GOES-R spacecraft instrument.

NASA’s RAVEN experiment will test autonomous docking technologies for spacecraft.

SAGE III and RAVEN were stowed in the Dragon’s unpressurized truck. Astronauts plucked them out of the trunk using the robotic arm and attached them to specified locations on the stations exterior to carry out their objectives.

For the return trip to Earth, the astronaut crew loaded Dragon with more than 5,400 pounds of NASA cargo, and science and technology demonstration samples gathered and collected by the stations crewmembers.

“A variety of technological and biological studies are returning in Dragon. The Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity,” said NASA.

“This information will provide insight into how human cancers start and spread, which aids in the development of prevention and treatment plans. Results from this investigation could lead to the treatment of disease and injury in space, as well as provide a way to improve stem cell production for human therapy on Earth.”

“Samples from the Tissue Regeneration-Bone Defect study, a U.S. National Laboratory investigation sponsored by the Center for the Advancement of Science in Space (CASIS) and the U.S. Army Medical Research and Materiel Command, studied what prevents vertebrates such as rodents and humans from re-growing lost bone and tissue, and how microgravity conditions affect the process. Results will provide a new understanding of the biological reasons behind a human’s inability to grow a lost limb at the wound site, and could lead to new treatment options for the more than 30 percent of the patient population who do not respond to current options for chronic non-healing wounds.”

Dragon departed in order to make way for the arrival of the next cargo ship.
