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.”

The brand new 29 story tall SpaceX Falcon 9 will deliver Intelsat 35e to a Geostationary Transfer Orbit (GTO).

The geostationary comsat will provide high performance services in the C- And Ku-bands to customers in North and South America, the Caribbean, as well as the continents of Europe and Africa.

The Ku band service includes a customized high power beam for direct-to-home television (DTH) and data communications services in the Caribbean as well as mobility services in Europe and Africa.

Hordes of spectators lined local area beaches and causeways north and south of the launch pad in anticipation of Sunday’s launch.

Many are expected to return given the promising weather forecast and July 4th holiday weekend.

The 229-foot-tall (70-meter) Falcon 9/Intelsat 353e rocket was raised erect Sunday morning, July 2 and is poised for liftoff and undergoing final prelaunch preparations.

The first and second stages will again be fueled with liquid oxygen and RP-1 propellants starting about one hour before liftoff.

Intelsat 35e marks the tenth SpaceX launch of 2017 – establishing a new single year launch record for SpaceX.

PORT CANAVERAL/KENNEDY SPACE CENTER, FL – The launch cadence at Elon Musk’s SpaceX is truly ramping up with Falcon 9 boosters rapidly coming and going in all directions from ground to space as the firm audaciously sets its sight on a third commercial payload orbital launch on July 2 in the span of just 9 days from its East and West Coast launch bases.

It was a magnificent sight to behold !! Seeing commercial passenger carrying cruise ships and commercial recycled rockets that will one day carry paying passenger to space, floating side by side in the busy channel of narrow Port Canaveral, basking in the suns glow from the sunshine state.

The doubly ‘flight-proven’ SpaceX Falcon 9 booster portends a promising future for spaceflight that Elon Musk hopes and plans will drastically slash the high cost of rocket launches and institute economic savings that would eventually lead to his dream of a ‘City on Mars!’ – sooner rather than later.

Thursday, June 29, serves as a perfect example of how SpaceX is rocking the space industry worldwide.

First, the reused first stage Falcon 9 booster from last Friday’s (June 23) SpaceX launch of the BulgariaSat-1 HD television broadcast satellite floated magnificently into Port Canaveral early Thursday morning atop the diminutive oceangoing droneship upon which it safely touched down upright on a quartet of landing legs some eight minutes after launch.

Second, SpaceX engineers then successfully conducted a late in the day static hot fire test of the Falcon 9 first stage engines and core that will power the next launch of the Intelsat 35e commercial comsat to orbit this Sunday, July 2.

So the day was just chock full of nonstop SpaceX rocketry action seeing a full day of rocket activities from dawn to dusk.

Thursday’s nonstop Space Coast action spanning from the north at the Kennedy Space Center and further south to Cape Canaveral Air Force Station and Port Canaveral was the culmination of space launch flow events that actually began days, weeks and months earlier.

The 156 foot- tall Falcon 9 booster had successfully landed on the tiny rectangular shaped “Of Course I Still Love You” or OCISLY droneship less than nine minutes after liftoff on Friday, June 23 on the BulgariaSat-1 flight.

That mission began with the picture perfect liftoff of the BulgariaSat-1 communications satellite for East European commercial broadband provider BulgariaSat at 3:10 p.m. EDT, or 19:10 UTC, June 23, with ignition of all nine of the ‘flight-proven’ Falcon 9 first stage engines on SpaceX’s seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

BulgariaSat is an affiliate of Bulsatcom, Bulgaria’s largest digital television provider.

The 15 story tall first stage touched down with a slight tilt of roughly eight degrees as a direct result of the extremely demanding landing regime.

Then after spending several post landing and launch days at sea due to stormy weather along the Florida Space Coast and to accommodate local shipping traffic and SpaceX planning needs, the booster at last neared shore from the south off the coast of Melbourne, FL.

Accompanied by a small armada of support vessels it was slowly towed to port by the Elsbeth III.

The SpaceX flotilla arrived at last at the mouth of Port Canaveral and Jetty Park Pier jutting into the Atlantic Ocean at about 830 a.m. EDT – offering a spectacular view at to a flock of space enthusiasts and photographers including this author.

I highly recommend you try and see a droneship arrival if all possible.

The leaning boosters – of which this is only the second – are even more dramatic!

Because the Falcon 9 barely survived the highest ever reentry force and landing heat to date, Musk reported.

Falcon 9’s first stage for the BulgariaSat-1 mission previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year.

Some two minutes and 40 seconds after liftoff the first and second stages separated.

As the second stage continued to orbit, the recycled first stage began the daunting trip back to Earth on a very high energy trajectory that tested the limits of the boosters landing capability.

“Falcon 9 will experience its highest ever reentry force and heat in today’s launch. Good chance rocket booster doesn’t make it back,” SpaceX founder and CEO Elon Musk wrote in a prelaunch tweet.

Following stage separation, Falcon 9’s first stage carried out two burns, the entry burn and the landing burn using a trio of the Merlin 1D engines.

Ultimately the 15 story tall booster successfully landed on the “Of Course I Still Love You” or OCISLY droneship, stationed in the Atlantic Ocean about 400 miles (600 km) offshore and east of Cape Canaveral.

“Rocket is extra toasty and hit the deck hard (used almost all of the emergency crush core), but otherwise good,” Musk tweeted shortly after the recycled booster successfully launched and landed for its second time.

BulgariaSat-1 and Iridium-2 counted as the eighth and ninth SpaceX launches of 2017.

Including those two ocean platform landings, SpaceX has now successfully recovered 13 boosters; 5 by land and 8 by sea, over the past 18 months.

Both landing droneships are now back into their respective coastal ports.

It’s a feat straight out of science fiction but aimed at drastically slashing the cost of access to space as envisioned by Musk.

KENNEDY SPACE CENTER, FL – With Sunday’s successful Falcon 9 blastoff for Iridium Communications joining rocketry’s history books, Elon Musk’s SpaceX accomplished a double headed American space spectacular this weekend with 2 launches and 2 booster landings in 2 days from 2 coasts for 2 commercial customers – in a remarkably rapid turnaround feat that set a new record for minimum time between launches for SpaceX.

On Sunday, June 25 at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 UTC) a SpaceX Falcon 9 rocket successfully launched a second set of ten Iridium Next mobile voice and data relay communications satellites to low Earth orbit on the Iridium-2 mission from SLC-4E on Vandenberg Air Force Base in California.

“All sats healthy and talking,” tweeted Matt Desch, Iridium Communications CEO, soon after launch and confirmation that all 10 Iridium NEXT satellites were successfully deployed from their second stage satellite dispensers. Iridium is a global leader in mobile voice and data satellite communications.

“It was a great day!”

The US West Coast Falcon 9 liftoff of the Iridium-2 mission from California on Sunday, June 25 took place barely 48 hours after the US East Coast Falcon 9 liftoff of the BulgariaSat-1 mission from Florida on Friday, June 23.

Without a doubt, Musk’s dream of rocket reusability as a here and now means to slash the high costs of launching to space and thereby broaden access to space for more players is rapidly taking shape.

Following separation of the first and second stages, the Falcon 9’s 15 story tall first stage successfully landed on the “Just Read the Instructions” droneship ocean going platform stationed several hundred miles out in the Pacific Ocean off the coast of California, despite challenging weather conditions.

Indeed the droneships position was changed in the final minutes before launch due to the poor weather.

“Droneship repositioned due to extreme weather. Will be tight,” tweeted Musk minutes before liftoff.

The 156 foot tall booster touched down about 8 and ½ minutes after liftoff from Vandenberg AFB.

Sunday’s Iridium 2 flight was Iridium Communications second contracted launch with SpaceX.

“This payload of 10 satellites was deployed into low-Earth orbit, approximately one hour after a SpaceX Falcon 9 rocket lifted off from Vandenberg,” Iridium said in a statement.

The Mini Cooper sized Iridium NEXT satellites each weigh 1,900 pounds, totaling approximately 19,000 pounds placed into space. That is the weight of a semi tractor trailer truck!

The inaugural Iridium 1 launch with the first ten Iridium Next satellites took place successfully at the start of this year on Jan. 14, 2017.

The new set of ten Iridium Next 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.

“Since the successful January 14, 2017 launch, Iridium NEXT satellites have already been integrated into the operational constellation and are providing service. The first eight operational Iridium NEXT satellites are already providing superior call quality and faster data speeds with increased capacity to Iridium customers. The two additional satellites from the first launch are continuing to drift to their operational orbital plane, where upon arrival they will begin providing service.”

Iridium 2 is the second of eight planned Falcon 9 launches to establish the Iridium NEXT constellation which will eventually consist of 81 advanced satellites.

At least 75 will be launched by SpaceX to low-Earth orbit, with 66 making up the operational constellation.

The inaugural launch of the advanced Iridium NEXT satellites in January 2017 started the process of replacing an aging Iridium fleet in orbit for nearly two decades.

Nine of the 81 will serve as on-orbit spares and six as ground spares.

“Now, and for approximately the next 45 days, these newly launched satellites will undergo a series of testing and validation procedures, ensuring they are ready for integration with the operational constellation,” said Iridium.

“We are thrilled with yesterday’s success. These new satellites are functioning well, and we are pressing forward with the testing process,” said Scott Smith, chief operating officer at Iridium.

“Since the last launch, the team at our Satellite Network Operations Center (SNOC) has been anxiously awaiting this new batch of satellites. There is a lot of work to do, and we are up for the challenge.”

KENNEDY SPACE CENTER, FL – In another breakthrough milestone aimed at slashing the high cost of rocketry, the innovators at billionaire entrepreneur Elon Musk’s SpaceX successfully launched a ‘used’ rocket for only the second time in history – that blazed a path to orbit with its BulgariaSat-1 commercial television comsat payload Friday afternoon, June 23, from the Kennedy Space Center and just minutes later landed upright and intact on an oceanic platform waiting offshore in the vast currents of the Atlantic ocean.

“This is really a great day for us,” Maxim Zayakov, CEO of BulgariaSat and Bulsatcom told Universe Today during pre and post launch interview’s onsite at NASA’s Kennedy Space Center in Florida.

“Everything is seeming to be a good success so far.”

To top that, SpaceX is targeting a bicoastal weekend doubleheader of launches signaling a remarkably rapid turnaround capability. Another Falcon 9 is scheduled for blastoff on Sunday, June 25 at 1:25 p.m. PDT (4:25 p.m. EDT; 2025 UTC) from Vandenberg Air Force Base in California on the Iridium-2 mission, less than 48 hours apart – which would set a new launch turnaround record for SpaceX.

The picture perfect liftoff of the BulgariaSat-1 communications satellite for East European commercial broadband provider BulgariaSat began at 3:10 p.m. EDT, or 19:10 UTC, June 23, with ignition of all nine of the ‘flight-proven’ Falcon 9 first stage engines on SpaceX’s seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

“Everything went down just as we expected,” BulgariaSat CEO Zayakov told me. “Of course there was a lot of excitement. And there are a lot of excited and scared feelings [with launches].”

“At the end of the day it not only worked out just as expected with the launch but the satellite also already reported in telemetry that she is doing fine,” Zayakov elaborated.

BulgariaSat-1 is the first geostationary communications satellite orbited for the nation of Bulgaria.

“We will start using it as soon as we can, in about one and a half months.”

The used 229-foot-tall (70-meter) SpaceX Falcon 9 carrying BulgariaSat-1 soared off historic pad 39A into brilliant mid-afternoon blue skies drenching the Florida Space Coast with beloved sunshine to the delight of hordes of spectators gathered from across the globe – including a Bulgarian TV crew witnessing their first launch.

History’s first ‘flight-proven’ Falcon 9 booster was successfully launched by SpaceX this past March for Luxembourg based telecommunications giant SES on the SES-10 mission – likewise from pad 39A.

Some 35 minutes after blastoff, BulgariaSat-1 was successfully separated as planned from the Falcon 9 second stage and deployed to its targeted initial geostationary transfer orbit (GTO).

“So now she is on her way to the orbital position. The solar arrays deployed about 30 minutes after spacecraft separation from the second stage.”

“Yes looking to the future we would be happy to use SpaceX again in the future, certainly why not. SpaceX is definitely up there,” Zayakov replied.

BulgariaSat-1 will be located at the Bulgarian orbital position at 1.9 degrees East longitude and will provide reliable satellite communications solutions to broadcast, telecom, corporate and government customers.

How many customers will be served? I asked Zayakov.

“BulgariaSat-1 will serve about 800,000 customers in Bulgaria and about another million subscribers elsewhere in eastern Europe and the Balkans,” Zayakov elaborated.

The BulgariaSat-1 geostationary comsat will provide direct-to-home television (DTH) and data communications services to Southeastern Europe, including Serbia, the Balkans and other European regions.

You could not have asked for better weather as the recycled Falcon 9 roared to life for the second time with a paying customer and put on a long and exciting space spectacle for those lucky and fortunate enough to witness history with their own eyeballs first hand and follow along for several minutes as the rocket accelerated magnificently to orbit and arched over to the African continent in the nearly cloudless sky.

Falcon 9’s first stage for the BulgariaSat-1 mission previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year.

Some two minutes and 40 seconds after liftoff the first and second stages separated.

As the second stage continued to orbit, the recycled first stage began the daunting trip back to Earth on a very high energy trajectory that tested the limits of the boosters landing capability.

“Falcon 9 will experience its highest ever reentry force and heat in today’s launch. Good chance rocket booster doesn’t make it back,” SpaceX founder and CEO Elon Musk wrote in a prelaunch tweet.

Following stage separation, Falcon 9’s first stage carried out two burns, the entry burn and the landing burn using a trio of the Merlin 1D engines.

Ultimately the 15 story tall booster successfully landed on the “Of Course I Still Love You” or OCISLY droneship, stationed in the Atlantic Ocean about 400 miles (600 km) offshore and east of Cape Canaveral.

“Rocket is extra toasty and hit the deck hard (used almost all of the emergency crush core), but otherwise good,” Musk tweeted shortly after the recycled booster successfully launched and landed for its second time.

The 156 foot tall first stage may have touched down with a slight tilt.

The OCISLY droneship is expected back into Port Canaveral in a few days.

The 8,100 pounds (3,700 kilograms) BulgariaSat-1 satellite was built by SSL in Palo Alto, Calif. It has a design lifetime for a 15-year mission.

BulgariaSat-1 is equipped with 2 Ku-band FSS transponders and 30 Ku-band BSS transponders for fixed satellite services and advanced television services such as high definition television.

With BulgariaSat-1 now safely in orbit, a period of critical testing and checkout is on tap next.

“It takes about ten days to arrive and stabilize at the final orbital slot,” Zayakov stated. “Then after those 10 days it takes about another 20 to 30 days to actually do all the orbital checkouts and orbital tests required to make sure that the satellite is performing fine and that we can start using it for broadcasts.”

“So in about one and a half months we will be ready to start using BulgariaSat-1.”

“We will start using it as soon as we can!”

The BulgariaSat-1 launch had originally been slated for this past Monday, June 19 but was delayed four days to fix a valve in the payload fairing.

“Postponing launch to replace fairing pneumatic valve,” Musk tweeted last Sunday. “It is dual redundant, but not worth taking a chance.”

And everything went off without a hitch!

BulgariaSat-1 counts as the eighth SpaceX launch of 2017.

KENNEDY SPACE CENTER, FL – For only the second time in history, SpaceX will launch a ‘flight-proven’ Falcon 9 rocket this Friday afternoon and the payload this time for this remarkable and science fictionesque milestone is the first geostationary communications satellite for the nation of Bulgaria.

Blastoff of the BulgariaSat-1 communications satellite for commercial broadband provider BulgariaSat is slated for early Friday afternoon, June 23 at 2:10 p.m. EDT, or 18:10 UTC from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

BulgariaSat is an affiliate of Bulsatcom, Bulgaria’s largest digital television provider. The geostationary comsat will provide direct-to-home television (DTH) and data communications services to Southeastern Europe, including the Balkans and other European regions.

All systems are GO at this point!

And if all goes well there is a definite possibility of a weekend bicoastal launch double header by SpaceX – says SpaceX billionaire founder and CEO Elon. The next Falcon 9 mission is scheduled for blastoff on Sunday, June 25 from Vandenberg Air Force Base in California, barely 48 hours apart.

SpaceX is maintaining a blistering launch pace this year.

The Falcon 9 booster arrived just hours after launch of the Dragon CRS-11 resupply mission for NASA on June 3 – as I witnessed the recycled rockets arrival at pad 39A first hand later the same day (see photos).

The late lunchtime liftoff time for BulgariaSat-1 offers a very convenient opportunity for everyone to enjoy an eyewitness view, regardless of whether you live locally or if have the availability to take a quick trip to the Florida Space Coast.

And the current weather outlook is excellent say forecasters.

You can watch the launch live on a SpaceX dedicated webcast starting about 15 minutes prior to the opening of the launch window at 2:10 p.m. EDT, or 18:10 UTC

Watch the SpaceX broadcast live at: SpaceX.com/webcast

The recycled Falcon 9’s launch window extends for a full two hours until 4:10 p.m. EDT, June 23, or 20:10 UTC.

Fridays weather forecast is currently 90% GO for favorable conditions at launch time. That’s about as good as it gets for the notoriously fickle central Florida region.

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

In case of a scrub for any reason on Friday, June 23, the backup launch opportunity is Saturday, June 24, at 2:10 p.m. EDT, or 18:10 UTC. Likewise it extends for two hours.

Saturdays’ weather forecast also quite good, dropping only slightly to 80% GO. The concern is for the Cumulus Cumulus Cloud Rule.

Falcon 9’s first stage for the BulgariaSat-1 mission previously supported the Iridium-1 mission from Vandenberg Air Force Base in January of this year. Following stage separation, Falcon 9’s first stage will attempt a landing on the “Of Course I Still Love You” droneship, which will be stationed in the Atlantic Ocean.

The satellite was built by SSL in Palo Alto, Calif. It has a design lifetime for a 15-year mission.

“We selected SSL to manufacture our first satellite early on, based on its history of success and reliability,” says Maxim Zayakov, chief executive officer of Bulgaria Sat. “SSL has been an excellent partner in helping us bring this project to fruition.”

BulgariaSat-1 will be equipped with 2 Ku-band FSS transponders and 30 Ku-band BSS transponders for fixed satellite services and advanced television services such as high definition television.

The historic pad 39A was previously used to launch NASA’s Apollo Saturn Moon rockets and Space Shuttles.

The path to launch was cleared following the successful completion of a critical static hot-fire test of the first stage last Thursday, June 15.

The hot fire test lasted about seven seconds as I witnessed from Banana River Lagoon and Rt. 1 in Titusville, which provides numerous excellent viewing locations.

Amazing Video: Watch SpaceX’s Dragon in Flight, as Seen From the Ground

A screenshot of video by Thierry Legault of the Dragon capsule and associated objects just 20 minutes after launch on June 3, 2017. Credit and copyright: Thierry Legault, used by permission.

Always on the lookout for interesting events in the skies, astrophotographer Thierry Legault has captured an incredible video of SpaceX’s Dragon capsule traveling through space just 20 minutes after it launched from Kennedy Space Center on June 3, 2017.

“You can see the Dragon, the second stage of the Falcon 9 rocket, and solar panel covers,” Legault told Universe Today via email, “plus a nice surprise I discovered during processing: several fast ejections of material, certainly thrusters firing!”

Legault captured at least 6 ejections of material during the passage over his location in Tours, France. The three brightest are highlighted at the end of this video. He used a Sony Alpha 7S with a 200mm lens.

So, what you’re seeing is the Dragon traveling through the background of stars. Legault hand-tracked the Dragon, so even though it appears as stationary (with a few bumps here and there) and objects are zooming past, the capsule is in fact moving at close to 17,500 mph (28,000 km/h). This was taken a just few minutes after the capsule separated from the Falcon nine upper stage and jettisoned the covers on the solar panels, so all the individual bright ‘dots’ seen here were still near each other, moving together in Earth orbit.

This Dragon is now docked at the International Space Station, as the launch was the CRS-11 (11 of 12 planned Commercial Resupply Services for SpaceX.) This was the first time that a Dragon spacecraft was reused, and it brought supplies and science experiments to the ISS. As SpaceX has now done several times, the first stage booster landed back at KSC. This was also the 100th launch from historic pad 39A. Read more about the launch and mission here.

This isn’t the first time Legault has captured the Dragon in flight; he also shot footage of Dragon on its way to the ISS in April of 2014. Recently, he also was able to take multiple images of the ISS passing in front of the Moon:

KENNEDY SPACE CENTER, FL – After threatening stormy skies over the Florida Space Coast miraculously parted just in the nick of time, the first ever recycled SpaceX Dragon cargo freighter blasted off on the 100th flight from historic pad 39A on the Kennedy Space Center (KSC) late Saturday afternoon June 3 – bound for the International Space Station (ISS) loaded with a science rich cargo from NASA for the multinational crew.

Nearly simultaneously the first stage booster accomplished another heart stopping and stupendous ground landing back at the Cape accompanied by multiple shockingly loud sonic booms screeching out dozens of miles (km) in all directions across the space coast region.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside Launch Complex 39A at KSC in Florida took place during an instantaneous launch window at 5:07 p.m. EDT Saturday, June 3, after a predicted downpour held off just long enough for the SpaceX launch team to get the rocket safely off the ground.

The launch took place after a 48 hour scrub from Thursday June 1 forced by stormy weather and lightning strikes came within 10 miles of pad 39A less than 30 minutes from the planned liftoff time.

The backup crew of 40 new micestonauts are also aboard for a first of its kind osteoporosis science study – that seeks to stem the loss of bone density afflicting millions of people on Earth and astronauts crews in space by testing an experimental drug called NELL-1. The 40 originally designated mice lost their coveted slot and were swapped out Friday due to the scrub.

The 213-foot-tall (65-meter-tall) SpaceX Falcon 9 roared to life off pad 39A upon ignition of the 9 Merlin 1 D first stage engines generating 1.7 million pounds of liftoff thrust and successfully delivered the Dragon bolted on top to low Earth orbit on course for the space station and jam packed with three tons of essential cargo.

Loading of the densified liquid oxygen and RP-1 propellants into the Falcon 9 first and second stages starting about 70 minutes prior to ignition. Everything went off without a hitch.

Dragon reached its preliminary orbit 10 minutes after launch and deployed its power generating solar arrays. It now set out on a carefully choreographed series of thruster firings to reach the space station Monday morning.

Following stage separation at 2 min 25 sec after liftoff, the first stage began a series of three burns (boostback, entry and landing) to carry out a precision propulsive ground landing back at Cape Canaveral Air Force Station, FL at Landing Zone-1 (LZ-1).

Thus overall SpaceX has now successfully recovered 11 boosters; 5 by land and 6 by sea, over the past 18 months – in a feat straight out of science fiction but aimed at drastically slashing the cost of access to space as envisioned by SpaceX billionaire CEO and founder Elon Musk.

Another significant milestone for this flight is that it features the first reuse of a previously launched Dragon. It previously launched on the CRS-4 resupply mission.

The recycled Dragon has undergone some refurbishments to requalify it for flight but most of the structure is intact, according to SpaceX VP for Mission Assurance Hans Koenigsmann.

The 20-foot high, 12-foot-diameter Dragon is carrying almost 5,970 pounds of science experiments and research instruments, crew supplies, food water, clothing, hardware, gear and spare parts to the million pound orbiting laboratory complex. This will support over 62 of the 250 research investigations and experiments being conducted by Expedition 52 and 53 crew members.

See detailed CRS-11 cargo mission cargo below.

Dragon CRS-11 marks SpaceX’s eleventh contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.

Falcon 9 streaked to orbit in spectacular fashion darting in and out of clouds for the hordes of onlookers and spectators who had gathered from around the globe to witness the spectacle of a rocket launch and booster landing first hand.

Dragon is loaded with “major experiments that will look into the human body and out into the galaxy.”

The flight will deliver investigations and facilities that study neutron stars, osteoporosis, solar panels, tools for Earth-observation, and more.

The unpressurized trunk of the spacecraft also will transport 3 payloads for science and technology experiments and demonstrations.

The truck payloads include the Roll-Out Solar Array (ROSA) solar panels, the Multiple User System for Earth Sensing (MUSES) facility which hosts Earth-viewing instruments and tools for Earth-observation and equipment to study neutron stars with the Neutron Star Interior Composition Explorer (NICER) payload.

NICER is the first ever space mission to study the rapidly spinning neutron stars – the densest objects in the universe. The launch coincidentally comes nearly 50 years after they were discovered by British astrophysicist Jocelyn Bell.

A second objective of NICER involves the first space test attempting to use pulsars as navigation beacons through technology called Station Explorer for X-Ray Timing and Navigation (SEXTANT).

Roll Out Solar Array (ROSA) is among the science investigations launching on the next SpaceX commercial resupply flight to the International Space Station, targeted for June 1, 2017.

If all goes well, Dragon will arrive at the ISS 2 days after launch and be grappled by Expedition 52 astronauts Peggy Whitson and Jack Fischer using the 57.7 foot long (17.6 meter long) Canadian-built robotic arm.

They will berth Dragon at the Earth-facing port of the Harmony module.

NASA TV will begin covering the Dragon rendezvous and grappling activities starting at 8:30 a.m. Monday.

Dragon CRS-11 is SpaceX’s second contracted resupply mission to launch this year for NASA.

The prior SpaceX cargo ship launched on Feb 19, 2017 on the CRS-10 mission to the space station. CRS-10 is further noteworthy as being the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.

Overall CRS-11 marks the 100th launch from pad 39A and the sixth SpaceX launch from this pad.

SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011. To date this is the sixth SpaceX launch from this pad.

Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.

KENNEDY SPACE CENTER, FL – The 100th blastoff from NASA’s historic pad 39A features a SpaceX Dragon resupply mission carrying three tons of science and crew supplies to the International Space Station (ISS) as well as another unfathomable ground landing of the Falcon 9 rockets first stage. UPDATE: Stormy weather and lightning scrubs launch until Saturday, June 3 at 5:07 p.m. EDT

40 micetonauts are also aboard for a first of its kind osteoporosis science study – that seeks to stem the loss of bone density afflicting millions of people on Earth and astronauts crews in space by testing an experimental drug called NELL-1. Update: The rocket was lowered into horizontal position in order to swap out the 40 micetonauts and other time critial cargo items.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 5:55 p.m. EDT Thursday, June 1.

Everything is on track for Thursday’s dinnertime launch of the 230 foot tall SpaceX Falcon 9 on the NASA contracted SpaceX CRS-11 resupply mission to the million pound orbiting lab complex.

However since the launch window is instantaneous there is no margin. In case any delays arise during the countdown due to technical or weather issues a 48 hour scrub to Saturday will result.

The launch is coincidently scheduled for dinnertime offering a spectacular opportunity for fun for the whole family as space enthusiasts flock in from around the globe.

Plus SpaceX will attempt a land landing of the 156 foot tall first stage back at the Cape at Landing Zone 1 some 9 minutes after liftoff.

To date SpaceX has successfully recovered 10 boosters, 4 by land and 6 by sea, over the past 18 months – in a feat straight out of science fiction but aimed at drastically slashing the cost of access to space.

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

The SpaceX/Dragon CRS-11 launch coverage will be broadcast on NASA TV beginning 5:15 p.m. on June 1. with additional commentary on the NASA launch blog.

SpaceX will also feature their own live webcast beginning approximately 20 minutes before launch at 5:35 p.m. EDT.

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

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

In the event of delay for any reason, the next launch opportunity is 5:07 p.m. Saturday, June 3, with NASA TV coverage starting at 4:30 p.m.

The weather looks somewhat iffy at this time with a 70% chance of favorable conditions at launch time according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base. The primary concerns on June 1 are for afternoon thunderstorms, anvil clouds and cumulus clouds.

The odds drop to 60% favorable for the scrub day on June 3.

The Dragon resupply ship dubbed Dragon CRS-11 counts as SpaceX’s eleventh contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.

The 20-foot high, 12-foot-diameter Dragon is carrying almost 5,970 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of Expedition 52 and 53 crew members.

The flight will deliver investigations and facilities that study neutron stars, osteoporosis, solar panels, tools for Earth-observation, and more.

The unpressurized trunk of the spacecraft also will transport 3 payloads for science and technology experiments and demonstrations.

NICER is the first ever space mission to study the rapidly spinning neutron stars – the densest objects in the universe. The launch coincidentally comes nearly 50 years after they were discovered by British astrophysicist Jocelyn Bell.

Dragon CRS-11 will be the second SpaceX resupply mission to launch this year.

The prior SpaceX cargo ship launched on Feb 19, 2017 on the CRS-10 mission to the space station. It was also the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.

They will berth Dragon at the Earth-facing port of the Harmony module. .

Overall CRS-11 marks the 100th launch from pad 39A and the sixth SpaceX launch from this pad.

SpaceX leased pad 39A from NASA in 2014 and after refurbishments placed the pad back in service this year for the first time since the retirement of the space shuttles in 2011. To date this is the sixth SpaceX launch from this pad.

Previous launches include 11 Apollo flights, the launch of the unmanned Skylab in 1973, 82 shuttle flights and five SpaceX launches.

KENNEDY SPACE CENTER VISITOR COMPLEX, FL – Following up last week’s announcement of NASA’s proposed Fiscal Year 2018 top line budget of $19.1 Billion by the Trump Administration, Universe Today spoke to NASA’ s Kennedy Space Center (KSC) Director Robert Cabana to get his perspective on the new budget and what it means for NASA and KSC; “Stay on the path!” – with SLS, Orion, ISS and Commercial Crew was his message in a nutshell.

The highlights of NASA’s $19.1 Billion FY 2018 budget request were outlined last week by NASA Acting Administrator Robert Lightfoot during a ‘State of NASA’ speech to agency employees held at NASA HQ, Washington, D.C. and broadcast to the public live on NASA TV on May 23.

In order to get a better idea of the implications of the 2018 NASA budget proposal for KSC, I spoke one-on-one with Robert Cabana – one of NASA’s top officials, who currently serves as Director of the Kennedy Space Center (KSC) as well as being a former astronaut and Space Shuttle Commander. Cabana is a veteran of four space shuttle missions.

How did NASA and KSC fare with the newly announced 2018 Budget?

“We at KSC and NASA as a whole did very well with the 2018 budget,” KSC Director Robert Cabana explained during an interview with Universe Today by the Rocket Garden at the Kennedy Space Center Visitor Complex (KSCVC) in Florida.

“I think it really solidifies that the President has confidence in us, on the path that we are on,” Cabana noted while attending a student robotics competition at KSCVC sponsored by NASA.

“With only a 1 percent cut – when you look at what other agency’s got cut – this budget allows us to stay on the path that we are on.”

Trump cut NASA’s 2018 budget request by $0.5 Billion compared to the recently enacted FY 2017 budget of $19.6 Billion approved by the US Congress and signed by the President.

Other Federal science agency’s also critically vital to the health of US scientific research such as the NIH, the NSF, the EPA, DOE and NIST suffered terrible double digit slashes of 10 to 20% or more.

KSC is the focal point for NASA’s human spaceflight programs currently under intense development by NASA – namely the Space Launch System (SLS) Mars megarocket, the Orion deep space crew capsule to be launched beyond Earth orbit (BEO) atop SLS, and the duo of Commercial Crew Program (CCP) space taxis being manufactured by Boeing and SpaceX that will ferry our astronauts to low Earth orbit (LEO) and the International Space Station (ISS).

Numerous NASA science missions also launch from the Florida Space Coast.

“At KSC the budget keeps us on a path that continues to provide a commercial crew vehicle to fly crews to the ISS in 2018,” Cabana stated.

“The budget also keeps us on track to launch SLS and Orion in 2019.”

“I think that’s really important – along with all the other stuff we are doing here at KSC.”

“From our point of view it’s a good budget. We need to press ahead and continue on with what we promised.”

What’s ahead for commercial crew at KSC?

“We are moving forward with commercial crew,” Cabana told me.

“Within the next calendar year [2018] we are moving ahead with flying the first certification flight with crew to the ISS. So that’s test flights and by the end of the year an actual crewed flight to the ISS. I want to see that happen.”

Industry partners Boeing and SpaceX are building the private CST-100 Starliner and Crew Dragon spaceships respectively, as part of NASA’s commercial crew initiative aimed at restoring America’s human spaceflight capability to launch our astronauts aboard American spaceships on American rockets from American soil.

Commercial Crew is a public/private partnership initiative with commercial contracts valued at $4.2 Billion and signed by Boeing and SpaceX with NASA in September 2014 under the Obama Administration.

The goal of commercial crew is to end our sole reliance on the Russian Soyuz capsule for astronaut flights to the space station since the retirement of the space shuttles back in 2011 – by manufacturing indigenous rockets and human rated spaceships.

However the CCP program suffered severe budget reductions by the US Congress for several years which forced significant work stretch-outs and delays in the maiden crew launches by both companies from 2015 to 2018 – and thus forced additional payments to the Russians for Soyuz seat purchases.

Both the Boeing Starliner and SpaceX Dragon crew vehicles can carry 4 or more astronauts to the ISS. This will enable NASA to add another crew member and thereby enlarge the ISS crew from 6 to 7 permanent residents after they become operational.

Meanwhile NASA is focusing on developing the SLS heavy lift rocket and Orion crew capsule with prime contractors Boeing and Lockheed Martin in an agency wide effort to send humans on a ‘Journey to Mars’ in the 2030s.

The European Space Agency(ESA) is also partnered with NASA and providing the service module for Orion.

What’s the status of the delivery of the European Space Agency’s service module?

“The service module will be here sometime next year,” Cabana said.

He noted that the details and exact timing are yet to be determined.

The first integrated launch of SLS and Orion on the unpiloted Exploration Mission-1 (EM-1) is now slated for sometime in 2019 after NASA recently slipped the date to the right from Fall 2018.

At the request of the Trump Administration, NASA also just completed a detailed study to ascertain the feasibility of adding a crew of two NASA astronauts to the EM-1 flight and launch it by the end of 2019.

In the end, NASA officials decided to stick with the baselined plan of no crew on EM-1 for a variety of technical and safety reasons, as well as cost – as I reported here.

I asked Cabana for his insight and opinion on NASA not adding crew to Orion on the EM-1 flight.

“No we are not launching crew on the first flight [EM-1],” Cabana stated.

“With the budget that we have and what we need to do, this is the answer we got to at the end.”

“You know the crew study was still very important. It allowed us to find some things that we should still do on [EM-1], even though we are not going to launch crew on that flight.

“So we will make some further modifications that will reduce the risk even further when we do fly crew [on the next flight of EM-2].”

So for 2017 what are the major milestone you hope to complete here at KSC for SLS and Orion?

“So for me here at the Kennedy Space Center, my goal for the end of this calendar year 2017 we will have completed all of the construction of all of the [ground systems] hardware and facilities that are necessary to process and launch the Space Launch System (SLS) and Orion,” Cabana elaborated.

‘We will still have a lot of work to do with the software for the spacecraft command and control systems and the ground systems.”

“But my goal is to have the hardware for the ground systems complete by the end of this year.”

What are those KSC facilities?

“Those facilities include the VAB [Vehicle Assembly Building] which will be complete to accept the mobile launcher in September and pad 39B will be complete in August,” Cabana said.

“The RPSF is already complete. The NPFF is already complete and we are doing testing in there. The LASF [Launch Abort System Facility] is complete – where they put the abort rocket on.”

“The Mobile Launcher will be complete from a structural point of view, with all the systems installed by the end of the year [including the umbilical’s and while room].”

SpaceX is targeting a June 1 blastoff for the firms next cargo delivery mission to the International Space Station (ISS) for NASA following today’s (May 28) successful test firing of the Falcon 9 booster’s main engines on the Florida Space Coast under sunny skies.

Liftoff of the SpaceX Falcon 9 rocket carrying the unmanned Dragon cargo freighter from seaside pad 39A at NASA’s Kennedy Space Center in Florida is slated for 5:55 p.m. EDT Thursday, June 1.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via Twitter soon after completion of the test at noon today 12 p.m. EDT.

“Targeting June 1 launch from historic Pad 39A for Dragon’s next resupply mission to the @Space_Station.”

The static fire test also apparently set off a brush fire near the pad which required a response from firefighters to douse the blaze with water bucket drops from helicopters.

“#USFWS firefighters are responding to a new wildfire at Merritt Island NWR caused by a static rocket test fire #FLfire,” tweeted the US Fish and Wildlife Service.

The wildfire stretched to 4 acres on Merritt Island and was successfully contained, the US Fish and Wildlife Service said.

With the launch conveniently coinciding with dinnertime, it will offer prime time viewing thrills for spectators and space enthusiasts coming from near and far.

The weather outlook for Thursday is currently promising with mostly sunny conditions but can change at a moments notice.

And to top that off SpaceX will attempt a land landing of the first stage back at the Cape at Landing Zone 1 some 9 minutes after liftoff.

The Dragon resupply ship dubbed Dragon CRS-11 counts as SpaceX’s eleventh contracted commercial resupply services (CRS) mission to the International Space Station for NASA since 2012.

It is carrying almost 6,000 pounds of science research, crew supplies and hardware to the orbiting laboratory in support of Expedition 52 and 53 crew members. The unpressurized trunk of the spacecraft also will transport solar panels, tools for Earth-observation and equipment to study neutron stars.

Dragon CRS-11 will be the second SpaceX resupply mission to launch this year.

The prior SpaceX cargo ship launched on Feb 19, 2017 on the CRS-10 mission to the space station. It was also the first SpaceX launch of a Falcon 9 from NASA’s historic pad 39A.

Another significant milestone for this flight is that it features the first reuse of a previously launched Dragon. It previously launched on the CRS-4 resupply mission.

Sunday’s brief static fire test involved a successful hot fire ignition test of the two stage rocket and all nine first stage Merlin 1D engines Sunday afternoon while the rocket was firmly held down at the pad.

The hold down engine test is routinely conducted to confirm the readiness of the engines and rocket for flight.

The nine Merlin 1D engines generate 1.7 million pounds of thrust for approximately three seconds.

The test simulates all the conditions of flight except liftoff, and involves loading of the densified liquid oxygen and RP-1 propellants into the first and second stages starting about 70 minutes prior to ignition.

The engine test was run without the Dragon cargo ship bolted on top.

The rocket was rolled out of the SpaceX processing hangar at the perimeter fence early this morning and then up the slight incline to the top of pad 39A. It was erected vertical to launch position using a dedicated transporter-erector.

With the successful completion of the static fire test, the booster will be rolled back to the big processing hangar and Dragon CRS-11 will be integrated on top.

NASA will offer live launch coverage on NASA Television and the agency’s website at beginning 5:15 p.m. on June 1.

In case of a delay for any reason, the next launch opportunity is 5:07 p.m. Saturday, June 3, with NASA TV coverage starting at 4:30 p.m.
