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.

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.”

KENNEDY SPACE CENTER, FL – SpaceX is targeting twilight thunder with the firms Falcon 9 rocketing skyward from the Florida Space Coast on Monday 15 carrying a commercial High-Speed broadband satellite for London based Inmarsat.

Blastoff of the Inmarsat-5 Flight 4 communications satellite for commercial broadband provider Inmarsat is slated for 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 SpaceX Falcon 9/ Inmarsat-5 Flight 4 is raised erect at the pad into launch position and poised for a twilight liftoff Monday.

All systems are currently GO and the weather outlook is quite favorable at this time.

The twilight setting will put on an outstanding sky show – if all goes well. But there are no guarantees.

So now is the time is come and watch a launch in person if you have the availability.

“Targeting launch of Inmarsat-5 Flight 4 from Pad 39A on Monday, May 15,” SpaceX confirmed via social media accounts.

The Falcon 9’s launch window extends for 49 minutes until 8:10 p.m. EDT.

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 will preclude 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.

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

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

The built from scratch 229-foot-tall (70-meter) SpaceX Falcon 9 is set to deliver the huge 6100 kg Inmarsat-5 F4 satellite to a Geostationary Transfer Orbit (GTO).

Mondays weather forecast is currently 80% GO for favorable conditions at launch time.

The concerns are for Cumulus clouds and Anvil clouds according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base.

In case of a scrub for any reason on May 15, the backup launch opportunity is Tuesday, May 16 at 7:21 p.m. EDT, or 23:21 UTC

The path to launch was cleared following the successful completion of a critical static hot-fire test of the first stage this past Thursday, May 11.

NASA Nixes Proposal Adding Crew to First SLS/Orion Deep Space Flight

KENNEDY SPACE CENTER, FL – After conducting a thorough review examining the feasibility of adding a two person crew to the first integrated launch of America’s new Space Launch System (SLS) megarocket and Orion capsule on a mission that would propel two astronauts to the Moon and back by late 2019, NASA nixed the proposal during a media briefing held Friday.

The announcement to forgo adding crew to the flight dubbed Exploration Mission-1 (EM-1) was made by NASA acting Administrator Robert Lightfoot during a briefing with reporters on May 13.

“We appreciate the opportunity to evaluate the possibility of this crewed flight,” said NASA acting Administrator Robert Lightfoot during the briefing.

“The bi-partisan support of Congress and the President for our efforts to send astronauts deeper into the solar system than we have ever gone before is valued and does not go unnoticed. Presidential support for space has been strong.”

Although the outcome of the study determined that NASA could be “technically capable of launching crew on EM-1,” top agency leaders decided that there was too much additional cost and technical risk to accommodate and retire in the limited time span allowed.

Lightfoot said it would cost in the range of $600 to $900 million to add the life support systems, display panels and other gear required to Orion and SLS in order to enable adding astronauts to EM-1.

“It would be difficult to accommodate changes needed to add crew at this point in mission planning.”

Thus NASA will continue implementing the current baseline plan for EM-1 that will eventually lead to deep space human exploration missions starting with the follow on EM-2 mission which will be crewed.

At the request of the new Trump Administration in February, NASA initiated a comprehensive two month long study to determine the feasibility of converting the first integrated SLS/Orion flight from its baselined uncrewed mission to cislunar space into a crewed mission looping around the Moon.

Had the crewed lunar SLS/Orion flight been approved it would have roughly coincided with the 50th anniversary the first human lunar landing by NASA astronauts Neil Armstrong and Buzz Aldrin during the Apollo 11 mission in July 1969.

Instead NASA will keep to the agencies current flight plan.

The first SLS/Orion crewed flight is slated for Exploration Mission-2 (EM-2) launching no earlier than 2021.

If crew had been added to EM-1 it would have essentially adopted the mission profile currently planned for Orion EM-2.

“If the agency decides to put crew on the first flight, the mission profile for Exploration Mission-2 would likely replace it, which is an approximately eight-day mission with a multi-translunar injection with a free return trajectory,” said NASA earlier. It would be similar to Apollo 8 and Apollo 13.

Orion is designed to send astronauts deeper into space than ever before, including missions to the Moon, asteroids and the Red Planet.

Orion crew module pressure vessel for NASA’s Exploration Mission-1 (EM-1) is unveiled for the first time on Feb. 3, 2016 after arrival at the agency’s Kennedy Space Center (KSC) in Florida. It is secured for processing in a test stand called the birdcage in the high bay inside the Neil Armstrong Operations and Checkout (O&C) Building at KSC. Launch to the Moon is slated in 2018 atop the SLS rocket. Credit: Ken Kremer/kenkremer.com

NASA is developing SLS and Orion for sending humans initially to cislunar space and eventually on a ‘Journey to Mars’ in the 2030s.

They are but the first hardware elements required to carry out such an ambitious initiative.

KENNEDY SPACE CENTER, FL – SpaceX is all set to continue their absolutely torrid launch pace in 2017 with a commercial High-Speed broadband satellite for Inmarsat on May 15 following Thursday’s successful completion of a critical static hot-fire test of the first stage. Watch our video below.

The static fire test of all 9 Merlin 1 D first stage engines comes just 10 days after the last successful SpaceX Falcon 9 liftoff of the super secret NROL-76 payload for the National Reconnaissance Office, or NRO – as I reported here.

The positive outcome for the static fire test of the first stage engines of the SpaceX Falcon 9 rocket on Thursday afternoon, May 11, paves the path to a Monday evening liftoff of the Inmarsat-5 F4 mission from the Florida Space Coast.

Blastoff of the Inmarsat-5 Flight 4 communications satellite for commercial broadband provider Inmarsat is slated for Monday evening, May 15 at 7:20 p.m. EDT (2320 GMT) from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via social media only minutes after finishing the key test at 12:45 p.m. EDT (1645 GMT).

“Targeting launch of Inmarsat-5 Flight 4 from Pad 39A on Monday, May 15.”

The launch window extends for 50 minutes until 8:10 p.m. EDT.

“The countdown begins!” Inmarsat confirmed on the company website.

“Static fire test complete & we are go for launch! #I5F4 will fly with SpaceX on 15 May 19:20 EDT / 00:20 BST.”

The weather forecast is currently 80% GO for favorable conditions at launch time.

The never used 229-foot-tall (70-meter) SpaceX Falcon 9 will deliver Inmarsat-5 F4 to a Geostationary Transfer Orbit (GTO).

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.

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

For the purposes of the engine test only the first and second stages of the Falcon 9 were rolled up the pad and erected.

Following the conclusion of the hot fire test the Falcon 9 was rolled back off the pad to the huge SpaceX processing hangar located just outside the pad perimeter fence.

The Falcon 9 rocket and Inmarsat payload have now been mated to the payload adapted and encapsulation inside the nose cone following the test. The integrated rocket and payload eill soon be rolled about a quarter mile up the ramp at pad 39A to undergo final prelaunch preparations.

“The #I5F4 satellite has been successfully mated to the payload adaptor and attach fitting and encapsulated into the payload fairing in preparation for our SpaceX launch on 15 May,” Inmarsat stated.

“It’s an emotional time for our Inmarsat and The Boeing Company engineers – the satellite will not be seen again before it is launched into geostationary orbit, nearly 36,000km from Earth!”

KENNEDY SPACE CENTER, FL – This week SpaceX blasted their first top secret surveillance satellite to orbit for America’s spy chiefs at National Reconnaissance Office (NRO) – affording magnificent viewing and imagery from the Florida Space Coast. Updated with more photos/videos – plus distinctly hear the sonic booms from pad 39A sending birds fleeing!

Liftoff of the classified NROL-76 payload for the NRO occurred soon after sunrise Monday morning, May 1, at 7:15 a.m. EDT (1115 GMT), from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

Less than nine minutes later, Space engineers managed to again recover the 15 story tall first stage booster by accomplishing a precise ground landing by perfectly targeting the vehicle for a propulsive soft landing at Cape Canaveral several miles south of the launch pad.

KENNEDY SPACE CENTER, FL – SpaceX today staged the stupendously successful Falcon 9 rocket launch at sunrise of a mysterious spy satellite in support of U.S. national defense for the National Reconnaissance Office (NRO) while simultaneously accomplishing a breathtaking pinpoint land landing of the boosters first stage that could eventually dramatically drive down the high costs of spaceflight.

Liftoff of the classified NROL-76 payload for the NRO took place shortly after sunrise this morning, Monday, May 1, at 7:15 a.m. EDT (1115 GMT), from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

The weather was near perfect and afforded a spectacular sky show for all those who descended on the Florida Space Coast for an up close eyewitness view of the rockets rumbling thunder.

The rocket roared off pad 39A after ignition of the nine Merlin 1D first stage engines generated some 1.7 million pounds of thrust.

The Falcon sped skyward darting in and out of wispy white clouds and appeared to head in a northeasterly direction from the space coast.

“A National Reconnaissance Office (NRO) payload was successfully launched aboard a SpaceX Falcon 9 rocket from Launch Complex 39A (LC-39A), Kennedy Space Center (KSC), Florida, at 7:15 a.m. EDT, on May 1, 2017,” the NRO said in a post launch statement.

“Thanks to the SpaceX team for the great ride, and for the terrific teamwork and commitment they demonstrated throughout. They were an integral part of our government/industry team for this mission, and proved themselves to be a great partner,” said Betty Sapp, Director of the National Reconnaissance Office.

The launch of the two stage 229 foot tall Falcon 9 was postponed a day after a last moment scrub was suddenly called on Sunday by the launch director at just about T minus 52 seconds due to a sensor issue in the first stage.

SpaceX engineers were clearly able to fully resolve the issue in time for today’s second launch attempt of the super secret NROL-76 for the NRO customer.

Barely nine minutes after the launch, the 156 foot tall first stage of the SpaceX Falcon 9 rocket made an incredibly precise and thrilling soft touchdown on land at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 39A.

The quartet of landing legs attached to the base of the first stage deployed only moments before touchdown – as can be seen in my eyewitness photos herein.

Multiple sonic booms screamed across the space coast as the 15 story first stage plummeted back to Earth and propulsively slowed down to pass though the sound barrier and safely came to rest fully upright.

This counts as SpaceX’s first ever launch of a top secret US surveillance satellite. It also counts as the fourth time SpaceX landed a first stage fully intact on the ground.

As is typical for NRO missions, nothing is publically known about the satellite nor has the NRO released any details about this mission in support of national security other than the launch window.

Overall SpaceX has now recovered 10 first stages via either land or at sea on an oceangoing platform.

NROL-76 marks the fifth SpaceX launch of 2017 and the 33rd flight of a Falcon 9.

NROL-76 is the second of five launches slated for the NRO in 2017. The next NRO launch is on schedule for August 14 from Vandenberg Air Force Base (VAFB), California by competitor ULA.

Until now launch competitor United Launch Alliance (ULA) and its predecessors have held a virtual monopoly on the US military’s most critical satellite launches.

The NRO is a joint Department of Defense–Intelligence Community organization responsible for developing, launching, and operating America’s intelligence satellites to meet the national security needs of our nation, according to the NRO.

KENNEDY SPACE CENTER, FL – A classified surveillance for the nation’s spymasters is set for blastoff shortly after sunrise on Sunday, Apr. 30 by SpaceX in a space first by the firm founded by billionaire entrepreneur Elon Musk that also features a ground landing attempt by the booster. Update: Scrub reset to May 1

Liftoff of the still mysterious NROL-76 classified payload for the National Reconnaissance Office, or NRO, is slated Sunday morning, April 30 from SpaceX’s seaside Launch Complex 39A on NASA’s Kennedy Space Center in Florida.

The Falcon 9 rocket and NROL-76 payload have been mated and rolled about a quarter mile up the ramp at pad 39A.

The 229-foot-tall (70-meter) Falcon 9/NROL-76 were raised erect this morning, Saturday, April 29 and are poised for liftoff and undergoing final prelaunch preparations.

The breakfast time launch window on Sunday, April 30 opens at 7 a.m. EDT (1100 GMT). It extends for two hours until 9.a.m. EDT.

The exact time of the spy satellite launch within the two hour window is classified at less than T Minus one day.

Spectators have been gathering from across the globe to witness the exciting launch and landing and area hotels are filling up.

A brand new Falcon 9 is being used for the launch unlike the recycled rocket utilized for the prior launch of the SES-10 mission involving history’s first reflown orbit class booster.

As is typical for NRO missions, nothing is publicly known about the satellite nor has the NRO released any details about this mission in support of national security other than the launch window.

We also know that this is the first launch of a spy satellite for the US governments super secret NRO spy agency by SpaceX and a source of pride for Musk and all SpaceX employees.

However you can watch the launch live on a SpaceX dedicated webcast starting about 20 minutes prior to the 7:00 am EDT opening of the window.

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

As is customary for all national security launches live coverage of the launch will cease approximately five minutes after liftoff as the secret payload makes it way to orbit.

However, SpaceX will continue their live webcast with complete coverage of the ground landing attempt back at the Cape which is a secondary objective of the launch.

Everything is on track for Sunday’s launch of the 229 foot tall SpaceX Falcon 9 on the NRO launch of NROL-76.

And the weather looks promising at this time.

Sunday’s weather outlook is currently forecasting an 80% chance of favorable conditions at launch time. The concerns are for cumulus clouds according to Air Force meteorologists with the 45th Space Wing at Patrick Air Force Base.

In case of a scrub for any reason on April 30, the backup launch opportunity Monday, May 1.

The path to launch was paved following a successful static hotfire test of the first stage booster on pad 39A which took place shortly after 3 p.m. Tuesday, April 25, as I reported here.

Until now launch competitor United Launch Alliance (ULA) and its predecessors have held a virtual monoploy on the US military’s most critical satellite launches.

The last first stage booster during the SES-10 launch of the first recycled rocket landed on a droneship barge at sea last month.

SpaceX will also attempt to achieve the secondary mission goal of landing the 156 foot tall first stage of the Falcon 9 rocket on land at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 39A.

This counts as the fourth time SpaceX will attempt a dramatic land landing potentially visible to hundreds of thousands of locals and tourists.

NROL-76 will be the fifth SpaceX launch of 2017.

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.

KENNEDY SPACE CENTER, FL – This week’s blastoff of the ‘SS John Glenn’ Cygnus cargo freighter atop an Atlas V rocket on a critical mission delivering over 7000 pounds of science and gear to the International Space Station (ISS) yielded stellar imagery from all around the Florida Space Coast.

On the occasion of what amounts to a sentimental third journey to space for NASA astronaut John Glenn – the first American to orbit Earth – near perfect weather conditions enabled spectacular views of the lunchtime liftoff of the United Launch Alliance Atlas V carrying Orbital ATK’s commercial Cygnus supply ship named in honor of a true American hero.

The SS John Glenn blasted to orbit on time at 11:11 a.m. EDT Tuesday, April 18 atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

The cargo ship safely reached the station early Saturday morning.

The stunning launch events were captured by journalists and tourists gathered from across the globe.

Four days after liftoff the SS John Glenn finally arrived at the station as planned Saturday morning April 22 following a carefully choreographed series of thruster maneuvers this past week.

The private Cygnus resupply vessel is carrying nearly four tons of science and supplies crammed inside for the five person multinational Expedition 51 crew.

After reaching the vicinity of the space station overnight Saturday, Cygnus was successfully captured by astronaut crew members Thomas Pesquet of ESA (European Space Agency) and Expedition 51 Station Commander Peggy Whitson of NASA at 6:05 a.m. EDT using the space station’s 57.7-foot (17.6-meter) Canadian-built Canadarm2 robotic arm.

The SS John Glenn Cygnus vehicle counts as Orbital ATK’s seventh cargo delivery flight to the station.

The vehicle is also known alternatively as the Cygnus OA-7 or CRS-7 mission.

Cygnus OA-7 is loaded with 3459 kg (7626 pounds) of science experiments and hardware, crew supplies, spare parts, gear and station hardware to the orbital laboratory in support over 250 research experiments being conducted on board by the Expedition 51 and 52 crews. The total volumetric capacity of Cygnus exceeds 27 cubic meters.
