SpaceX Stages Stunning Sunset Blastoff as Recycled Falcon 9 Soars to Orbit with SES/EchoStar HDTV Sat; Booster Re-Lands at Sea

SpaceX's reusable rockets are bringing down the cost of launching things into space, but the cost is still prohibitive. Any weight savings contribute to missions feasibility, including a reduction in food supplies for long space journeys.

KENNEDY SPACE CENTER, FL – SpaceX staged a stunning sunset blastoff this evening Oct. 11, of the commercial SES-11/EchoStar 105 HDTV satellite that will serve the everyday needs of millions of customers across North America as it soared to geostationary orbit on a recycled Falcon 9 from the Florida Space Coast.

Minutes later the now doubly ‘flight-proven’ booster safely made its way back to Cape Canaveral after reigniting its engines to carry out another upright soft landing and recovery – that potentially sets the stage for an unprecedented third launch.

The private SES-11/EchoStar 105 communications satellite mission made an on time liftoff of the recycled first stage booster at dinnertime Wednesday Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

SpaceX successfully delivered the nearly six ton EchoStar 105/SES-11 joint mission satellite for SES and ExchoStar to geostationary transfer orbit some 22,000 miles (36,000 kilometers) above the equator.

“Successful deployment of EchoStar 105/SES-11 to geostationary transfer orbit confirmed,” said SpaceX.

Remarkably today’s launch was the second launch for SpaceX this week following Monday’s Falcon 9 launch from Vandenberg AFB, Ca., carrying 10 Iridium-NEXT satellites to orbit – and a record setting 15th of 2017!

The launch, landing and satellite deployment were broadcast live on a SpaceX hosted webcast.

The weather was near perfect and there was scarcely a cloud in the sky. Space enthusiasts who traveled far and wide from around the globe to witness a launch were richly rewarded with time and money well spent.

That’s in stark contrast to the horrible weather conditions existing just days ago that forced a part of weather scrubs for the ULA Atlas V. Launch of the NROL-52 spy satellite is currently rescheduled for Sat., Oct 14.

EchoStar 105/SES-11 is a high-powered hybrid Ku and C-band communications satellite launching as a dual-mission satellite for US-based operator EchoStar and Luxembourg-based operator SES.

The used two stage 229-foot-tall (70-meter) Falcon 9 rocket was rolled out to pad 39A Tuesday to ready it for today’s liftoff.

The EchoStar 105/SES-11 spacecraft was built by Airbus and shipped from the Airbus facilities in Toulouse, France to Cape Canaveral, FL for flight processing.

The satellite was successfully deployed as planned approximately 36 minutes after liftoff.

“SES-11 is a high-powered communications satellite designed to especially accelerate the development of the US video neighbourhood, and the delivery of HD and UHD channels. Optimised for digital television delivery, SES-11 joins SES-1 and SES-3 at the centre of its robust North American orbital arc, which reaches more than 100 million TV homes. Together with SES-1 and SES-3, SES-11 will be utilised for the expansion of the North America Ultra HD platform,” according to SES.

“SES-11 offers comprehensive coverage over North America, including Hawaii, Mexico and the Caribbean, and will also empower businesses and governments to capture new opportunities and expand their reach across the region.”

The 5,200 kg (11,500 pounds) satellite was encapsulated inside the payload fairing and integrated with the Falcon 9 rocket.

SES was the first company to ever fly a payload on a ‘flight-proven’ Falcon 9. The SES-10 satellite lifted off successfully this spring on March 30, 2017.

The second reflown booster successfully launched the BulgariaSat-1 a few months later.

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

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

“Falcon 9 first stage has landed on Of Course I Still Love You — third successful mission with a flight-proven orbital class rocket,” said SpaceX.

This marked the 18th successful landing of a recovered Falcon 9 first stage booster.

This booster originally flew on the NASA Dragon CRS-10 resupply mission to the International Space Station in February of this year.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 11 launch and was prepositioned in the Atlantic Ocean some 400 miles (600 km) off the US East coast, just waiting for the boosters 2nd approach and pinpoint propulsive soft landing.

The booster was outfitted with four grid fins and four landing legs to accomplish the pinpoint touchdown on the barge at sea.

The last SpaceX Falcon 9 launch from KSC took place on Sep. 7 carrying the USAF X-37B military space plane to orbit just ahead of Hurricane Irma.

Watch for Ken’s continuing onsite coverage of SpaceX SES-11, ULA NROL-52 and NASA and space mission reports direct from the Kennedy Space Center and Cape Canaveral Air Force Station, Florida.

To date SpaceX has successfully recovered 18 first stage boosters by land and sea.

The SES-11 stage is expected back in Port Canaveral in a few days if all goes well.

SpaceX Falcon 9 Dazzles Delivering ‘Epic’ Intelsat DTH TV Comsat to Orbit for America’s

SpaceX Falcon 9 blasts off with Intelsat 35e - 4th next gen ‘Epic’ comsat for Intelsat - on July 5, 2017 at 7:37 p.m. EDT from Launch Complex 39A at NASA's Kennedy Space Center in Florida. Credit: Ken Kremer/kenkremer.com

KENNEDY SPACE CENTER, FL – The third time proved to be the charm as SpaceX kept up a torrid 2017 launch pace and successfully ignited another Falcon 9 rocket late Wednesday, July 5, from the Florida Space Coast and delivered a powerful and heavy weight commercial TV satellite to orbit that will serve “tens of millions of customers globally,” Intelsat VP for Sales Kurt Riegel, told Universe Today at NASA’s Kennedy Space Center press site.

The SpaceX Falcon 9 put on a dazzling near dusk display as it roared off historic launch pad 39A on SpaceX’s tenth launch of 2017 Wednesday evening into brilliant blue skies with scarcely a cloud to be seen and delightfully summer weather conditions.

Blastoff of the Falcon 9 carrying the Intelsat 35e communications satellite for commercial high speed broadband provider Intelsat occurred right on time at dinnertime July 5 at 7:38 p.m. EDT, or 2338 UTC from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

The thunderous blastoff wowed hordes of spectators gathered along space coast beaches and causeways and local residential neighborhoods from came across the globe to witness and the launch spectacle and many of whom will be users of and benefit from the services offered by Intelsat 35e.

“Tens of millions of customers will be served and be touched by Intelsat 35e,” Intelsat VP for Sales & Marketing Kurt Riegel, told Universe Today in an exclusive interview beside the iconic countdown clock at NASA’s Kennedy Space Center Florida press site.

Wednesday’s liftoff finally took place safely after back to back last moment scrubs on Sunday and Monday (July 2/3) kept Falcon 9 from igniting its engine for the delayed journey to orbit.

Elon Musk told the SpaceX launch and engineering team to stand down over the 4th of July holiday and instead thoroughly investigate the root cause of the pait of launch aborts.

The near scrubs resulted from insidious anomaly not detected after the initial launch abort on Sunday, July 2.

Intelsat 35e will be utilized by copious public, government and commercial clients throughout the Americas, Europe and Africa.

The 23 story tall Falcon 9 lofted Intelsat’s commercial Epic 35e next-generation high throughput satellite to geostationary transfer orbit.

It separated from the Falcon 9 upper stage as planned about a half hour after liftoff.

“The Intelsat 35e satellite separated from the rocket’s upper stage 32 minutes after launch, at 8:10 pm EDT, and signal acquisition has been confirmed,” Intelsat announced post launch..

“This was the SpaceX’s first satellite launch contracted by Intelsat,” Ken Lee, Intelsat’s senior vice president of space systems, told Universe Today in a prelaunch interview on Sunday.

“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.”

SpaceX has now safely and successfully demonstrated an amazing launch pace with 3 rockets propelled aloft in the span of just 12 days from both US coasts. Had Intelsat 35e been launched on Sunday, July 3, it would have established and even faster record pace of 3 launches in just 9 days.

“The successful launch of Intelsat 35e is a major milestone in our business plan for 2017, furthering the footprint and resilience of our Intelsat EpicNG infrastructure,” said Stephen Spengler, Chief Executive Officer, Intelsat, in a statement.

“With each Intelsat EpicNG launch, we advance our vision of creating a global, high performance for our customers that will unlock new growth opportunities in applications including mobility, wireless infrastructure and private data networks. As we further our innovations with respect to ground infrastructure and managed service offerings, like IntelsatOne Flex, we are transforming the role of satellite in the telecommunications landscape.”

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

The first stage was not recovered for this launch because the massive 6800 kg (13000 lb) Intelsat 35e comsat requires every drop of fuel to get to the desired orbit.

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

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

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

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.

The rectangularly shaped OCISLY droneship is tiny – barely the size of a moderately sized apartment complex parking lot.

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 – 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.

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.

SpaceX Blasts Biggest High Speed Communications Satellite to Orbit for Inmarsat

SpaceX Falcon 9 rocket carrying commercial Inmarsat 5 F4 broadband satellite blasts off to geostationary orbit at twilight at 7:20 p.m. EDT from Launch Complex 39A on 15 May 2017 from NASA’s Kennedy Space Center in Florida. Credit: Ken Kremer/Kenkremer.com

KENNEDY SPACE CENTER, FL – SpaceX blasted the “largest and most complicated communications satellite ever built to orbit” for London based Inmarset at twilight this evening, May 15, from NASA’s Kennedy Space Center aboard an expendable Falcon 9 rocket.

In fact the Inmarsat-5 F4 satellite is so powerful that it has the potential to reach “hundreds of millions of customers” the Inmarsat CEO Rupert Pierce told Universe Today in a post launch interview at the Kennedy Space Center.

“This is the largest and most complicated [communications] satellite ever built,” Pearce explained beside NASA’s countdown clock at the KSC press site.

Blastoff of the Inmarsat-5 Flight 4 communications satellite for commercial High-Speed mobile broadband provider Inmarsat took place right on time early Monday evening, May 15 at 7:21 p.m. EDT (or 23:21 UTC) from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

The newly built 229-foot-tall (70-meter) SpaceX Falcon 9 successfully delivered the huge 6100 kg Inmarsat-5 F4 satellite to a Geostationary Transfer Orbit (GTO) under brilliant blue twilight skies from the Florida Space Coast.

“Satellite deployment success!” Inmarsat announced.

“#I5F4 has been released & is flying high on its way to geostationary orbit! Safe journey! Thanks for a great launch SpaceX!”

Why launch such the largest and most complicated satellite ever? I asked Inmarsat CEO Pearce.

“We set a very high bar for the service offerings we want to offer for that satellite that just went up and is now on its way to in orbit testing,” Inmarsat CEO Pearce told me.

“That satellite will deliver mobile broadband for a third of the Earth at 50 megabits per second.”

“And by the end of next year those data rates will go up to over 300 megabits per second.”

“To get that kind of data speed you need very high processing powers, you need to deploy the new Ka band – which although it is still relatively unproven is looking like a very exciting new capability for space assets.”

The integrated Falcon 9/Inmarsat-5 F4 were rolled out to the KSC launch pad on Sunday to begin final preparations and were erected at the pad this morning for Monday’s liftoff.

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

It will now be “manoeuvred to its geostationary orbit, 35,786km (22,236 miles) above Earth, where it will deploy its solar arrays and reflectors and undergo intensive payload testing before beginning commercial service.”

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.

KENNEDY SPACE CENTER, FL – The opening volley of March Launch Madness started brilliantly as showcased by stunning imagery of the inaugural nighttime launch of a SpaceX Falcon 9 off historic pad 39A under moonlit skies along the Florida Space Coast on Thursday, March 15.

The 229 foot tall Falcon 9 rocket thundered to life at 2:00 a.m. EDT Thursday, March 16 on a commercial liftoff from Launch Complex 39A on NASA’s Kennedy Space Center and successfully delivered the high capacity EchoStar XXIII TV broadcast satellite to geosynchronous orbit for Brazil.

Check out the expanding spectacular gallery of launch photos and videos gathered from my space journalist colleagues, myself and spectators ringing the space coast.

Besides being the first night launch of a Falcon 9 from pad 39A, the mission also goes down as the first fully commercial launch from pad 39A.

Overall the EchoStar XXIII launch counts as only the second Falcon 9 ever to blast off from pad 39A.

The inaugural Falcon 9 blastoff successfully took place last month on Feb. 19 on a contracted cargo resupply mission for NASA that delivered over 2.7 tons of science experiments, crew supplies and research gear to the International Space Station (ISS) on the SpaceX CRS-10 Dragon spaceship – as I reported here.

SpaceX’s billionaire CEO Elon Musk leased historic pad 39A from NASA back in April 2014 for launches of the firms Falcon 9 and Falcon Heavy carrying both robotic vehicles as well as humans on missions to low Earth orbit, the Moon and ultimately the Red Planet.

After a short delay due to wind issues, the Falcon 9’s nine Merlin 1D first stage engines ignited at 2:00 a.m. EDT March 16, generating 1.7 million pounds of liftoff thrust to propel the commercial EchoStar 23 telecommunications satellite off pad 39A and on its way to a Geostationary Transfer Orbit (GTO) for EchoStar Corporation.

The satellite was deployed approximately 34 minutes after launch.

With Falcon away, the launch dates have been rescheduled for Saturday, March 18 and Friday, March 24 respectively.

Indeed the potential for a grand slam of launches also exists with another Falcon 9 blastoff at the very end of this month – if all goes well. But first we have to get through the Delta and Atlas launches and deal with finicky Florida weather.

KENNEDY SPACE CENTER, FL – Under stellar moonlit Florida skies, a private SpaceX Falcon 9 took flight overnight and flawlessly delivered the commercial EchoStar 23 television satellite to geosynchronous orbit after high winds delayed the rockets roar to orbit by two days from Tuesday. Breaking News: Check back for updates

The post midnight spectacle thrilled spectators who braved the wee hours this morning and were richly rewarded with a rousing rush as the 229 foot tall Falcon 9 rocket thundered to life at 2:00 a.m. EDT Thursday, March 16 from historic Launch Complex 39A on NASA’s Kennedy Space Center and sped to orbit.

Rising on the power of 1.7 million pounds of liftoff thrust generated by nine Marlin 1D first stage engines, the two stage Falcon 9 rocket successfully delivered the commercial EchoStar 23 telecommunications satellite to a Geostationary Transfer Orbit (GTO) for EchoStar Corporation.

The satellite was deployed approximately 34 minutes after launch.

Thus began March Launch Madness !!

If all goes well, March features a triple header of launches with launch competitor and arch rival United Launch Alliance (ULA) planning a duo of nighttime blastoffs from their Delta and Atlas rocket families. The exact dates are in flux due to the earlier postponement of the SpaceX Falcon 9. They have been rescheduled for March 18 and 24 respectively.

EchoStar 23 will be stationed over Brazil for direct to home television broadcasts and high speed voice, video and data communications to millions of customers for EchoStar.

It was designed and built by Space Systems Loral (SSL).

“EchoStar XXIII is a highly flexible, Ku-band broadcast satellite services (BSS) satellite with four main reflectors and multiple sub-reflectors supporting multiple mission profiles,” according to a description from EchoStar Corporation.

EchoStar XXIII will initially be deployed in geosynchronous orbit at 45° West. The Satellite End of Life (EOL) Power is 20 kilowatts (kW).

The entire launch sequence was broadcast live on a SpaceX hosted webcast that began about 20 minutes before the revised liftoff time of 2:00 a.m. from the prelaunch countdown, blastoff and continued through the dramatic separation of the EchoStar 23 private payload from the second stage.

The EchoStar 23 launch counts as only the second Falcon 9 ever to blast off from pad 39A.

The inaugural Falcon 9 blastoff successfully took place last month on Feb. 19, as I reported here.

However unlike most recent SpaceX missions, the legless Falcon 9 first stage will not be recovered via a pinpoint propulsive landing either on land or on a barge at sea.

Because of the satellite delivery to GTO, there are insufficient fuel reserves to carry out the booster landing.

“SpaceX will not attempt to land Falcon 9’s first stage after launch due to mission requirements,” officials said.

Therefore the first stage is not outfitted with either landing legs or grid fins to maneuver it back to a touchdown.

SpaceX announced that this was the last launch of an expendable Falcon 9.

Recovered SpaceX Falcon 9 ‘Lifts Off’ 2nd Time After ‘Baby Made it Home!” – Gallery

PORT CANAVERAL, FL – The spent SpaceX Falcon 9 first stage booster that sped to space and back and landed safely at sea, ‘lifted off’ for a second time so to speak after CEO Elon Musk’s “Baby Made it Home” to her home port around lunchtime on June 2 – as I witnessed and reported here for Universe Today.

“Yay, baby made it home,” SpaceX CEO and billionaire founder Elon Musk exuberantly tweeted with a link to my port arrival story and photos showing the tilted booster radiantly floating atop the droneship landing platform.

Photos above and below from myself and colleagues capture Falcon’s 2nd ‘lift off’ – this time at dusk on June 2, via crane power as workers hoisted it off its ocean landing platform – with an American flag flying proudly below – onto a ground based work platform to carry out initial processing.

The booster triumphantly entered the waterway into Port Canaveral, Fl by way of the ocean mouth at Jetty Park pier at about 11: 45 a.m. on June 2 under clear blue skies.

It continued sailing serenely along the Port Canaveral channel – towed behind the Elsbeth III tugboat – making a picture perfect tour for lucky spectators for another 30 minutes or so until docking at the SpaceX ground processing facility.

All in all it was quite appropriately an ‘otherworldly’ scene reminiscent of a great scifi movie.

Watch this video from my photojournalist colleague Jeff Seibert.

The beaming 156-foot-tall Falcon 9 booster had propulsively landed six days earlier atop the specially designed SpaceX ‘droneship’ named “Of Course I Still Love You” or “OCISLY” less than 9 minutes after the spectacular May 27 blastoff.

The Falcon 9 was leaning some 5 degrees or so on the droneship upon which it had landed on May 27 while it was stationed approximately 420 miles (680 kilometers) off shore and east of Cape Canaveral, Florida, surrounded by the vastness of the Atlantic Ocean.

After docking, SpaceX workers then spent the next few hours carefully maneuvering and attaching a pyramidal shaped metal hoisting cap by crane to the top of the 15 story tall first stage – as it was firmly secured to the deck of the droneship via multiple tie downs.

It was a delicately choreographed and cautiously carried out operation, complicated by the fact that this used, returned booster was tilted. The prior two sea landed Falcon 9 boosters landed perfectly upright in April and May.

Indeed a pair of technicians had to ride a cherry picker lift to the very top to help fasten the cap securely in place as it was slowly lowered in the late afternoon.

Workers then spent several more hours undoing and removing the tiedowns to the droneship deck, one by one.

Finally and with no fanfare the ‘GO’ command was suddenly given.

At dusk, Falcons 2nd ‘ascent’ began at around 8 p.m. The small group of us patiently watching and waiting all day from across the channel had no warning or advance notice. My guestimate is Falcon rose perhaps 30 to 40 feet.

It was craned over to the right and lowered onto the waiting ground based retention work platform. Altogether the whole movement took some 10 minutes.

The SpaceX Falcon 9 began its rapid journey to space and back roaring to life at 5:39 p.m. EDT last Friday, May 27, from Space Launch Complex-40 at Cape Canaveral Air Force Station, FL, ascending into sky blue sunshine state skies.

The Falcon 9 was carrying the Thaicom-8 telecommunications satellite to orbit as its primary goal for the commercial launch from a paying customer.

It roared to life with 1.5 million pounds of thrust from the first stage Merlin 1 D engines and successfully propelled the 7000 pound (3,100 kilograms) commercial Thai communications satellite to a Geostationary Transfer Orbit (GTO).

Landing on the droneship was a secondary goal of SpaceX’s visionary CEO and founder Elon Musk.

It was leaning due to the high speed reentry and a touchdown landing speed near the maximum sustainable by the design.

“Rocket landing speed was close to design max & used up contingency crush core, hence back & forth motion,” tweeted SpaceX CEO Elon Musk.

“Prob ok, but some risk of tipping.”

That tilting added significant extra technical efforts by the SpaceX workers to stabilize it at sea and bring it back safely and not tip over calamitously during the six day long sea voyage back to home port.

““Rocket back at port after careful ocean transit. Leaning back due to crush core being used up in landing legs,” SpaceX explained.

What is the crush core?

“Crush core is aluminum honeycomb for energy absorption in the telescoping actuator. Easy to replace (if Falcon makes it back to port),” Musk tweeted during the voyage home.

The landing leg design follows up and improves upon on what was used and learned from NASA’s Apollo lunar landers in the 1960s and 1970s.

“Falcon’s landing leg crush core absorbs energy from impact on touchdown. Here’s what it looked like on Apollo lander,” noted SpaceX

Technicians started removing the quartet of landing legs on Friday. I observed the first one being detached late Friday, June 3.

The booster was rotated horizontally after all the legs were removed and transported back to the SpaceX processing hangar at the Kennedy Space Center at Launch Complex 39A.

The three prior landed boosters were all moved to 39 A for thorough inspection, analysis and engine testing. One will be refurbished and recycled for reuse.

Later this year, SpaceX hopes to relaunch one of the recovered first stage boosters.

The SpaceX rockets and recovery technology are all being developed so they will one day lead to establishing a ‘City on Mars’ – according to the SpaceX’s visionary CEO and founder Elon Musk.

Musk aims to radically slash the cost of launching future rockets by recycling them and using them to launch new payloads for new paying customers.

Musk hopes to launch humans to Mars by the mid-2020s.

The recovered SpaceX first stage booster that nailed a spectacular middle-of-the-night touchdown at sea last week sailed back to Port Canaveral, Florida, late Monday and was transferred by crane on Tuesday from the drone ship to land – as seen in an amazing time-lapse video and photos, shown above and below and obtained by Universe Today.

The exquisite up close time-lapse sequence shows technicians carefully hoisting the 15-story-tall spent booster from the drone ship barge onto a work pedestal on land some 12 hours after arriving back in port.

The time-lapse imagery (below) of the booster’s removal from the drone ship was captured by my space photographer friend Jeff Seibert on Tuesday, May 10.

Towards the end of the video there is a rather humorous view of the technicians climbing in unison to the bottom of the hoisted Falcon.

“I particularly like the choreographed ascent by the crew to the base of the Falcon 9 near the end of the move video,” Seibert told Universe Today.

The move took place from 11:55 AM until 12:05 PM, Seibert said.

The booster was towed into the space coast port around 11 p.m. Monday night, as seen in further up close images captured by my space photographer friend Julian Leek.

Leek also managed to capture a stunningly unique view of the rocket floating atop the barge when it was still out at sea and some 5 miles off shore waiting to enter the port at a safe time after most of the cruise ships had departed – as I reported earlier here.

The 156 foot tall booster safely soft landed on the drone ship named “Of Course I Still Love You” or “OCISLY” barely nine minutes after liftoff of the SpaceX Falcon 9 last week on a mission to deliver the Japanese JCSAT-14 telecom satellite to a Geostationary Transfer Orbit (GTO).

The upgraded SpaceX Falcon 9 soared to orbit on May 6, roaring to life with 1.5 million pounds of thrust on a mission carrying the JCSAT-14 commercial communications satellite, following an on time liftoff at 1:21 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station, Fl.

The first stage then carried out a propulsive soft landing on the ocean going platform located some 400 miles off the east coast of Florida.

To date SpaceX has recovered 3 Falcon 9 first stages. But this was the first one to be recovered from the much more demanding, high velocity trajectory delivering a satellite to GTO.

The first rocket was flying faster and at a higher altitude at the time of seperatoin from the second stage and thus was much more difficult to slow down and maneuver back to the ocean based platform.

Thus SpaceX officials and CEO Elon Musk had been openly doubtful of a successful outcome for this landing attempt.

“First landed booster from a GTO-class mission (final spacecraft altitude will be about 36,000 km),” tweeted SpaceX CEO and founder Elon Musk.

The commercial SpaceX launch lofted the JCSAT-14 Japanese communications satellite to a Geostationary Transfer Orbit (GTO) for SKY Perfect JSAT – a leading satellite operator in the Asia – Pacific region.

The landing counts as another stunning success for Elon Musk’s vision of radically slashing the cost of sending rocket to space by recovering the boosters and eventually reusing them.

The next step is to defuel the booster and remove the landing legs. Thereafter it will be tilted and lowered horizontally and then be placed onto a multi-wheeled transport for shipment back to SpaceX launch facilities at Cape Canaveral for refurbishment, exhaustive engine and structural testing.

The newly recovered first stage will join a fleet of two others recovered last December and in April.

“May need to increase size of rocket storage hangar,” tweeted Musk.

If all goes well the recovered booster will eventually be reflown.

The next SpaceX commercial launch is tentatively slated for the late May/early June timeframe.
