BREAKING NEWS- A SpaceX Falcon 9 rocket and its Israeli commercial satellite payload were completely destroyed this morning, Thursday, September 1, during launch preparations ahead of the scheduled liftoff on Saturday, September 3.
The explosion occurred at approximately 9:07 a.m. this morning at the SpaceX launch facilities at Space Launch Complex 40 on Cape Canaveral Air Force Station, according to a statement from the USAF 45th Space Wing Public Affairs office.
Watch for additional details here and my interview on the BBC as this story is being frequently updated:
There were no injuries reported at this time.
SpaceX was preparing to conduct a routine static fire test of the first stage Merlin 1 D engine when the explosion took place this morning.
SpaceX media relations issued this statement:
“SpaceX can confirm that in preparation for today’s static fire, there was an anomaly on the pad resulting in the loss of the vehicle and its payload. Per standard procedure, the pad was clear and there were no injuries.”
The SpaceX Falcon 9 had been slated for an overnight blastoff on Saturday, September 3 at 3 a.m. from pad 40 with the AMOS-6 telecommunications satellite valued at some $200 million.
SpaceX sells Falcon 9 rockets at a list price of some $60 million.
This would have been the 9th Falcon 9 launch of 2016.
This explosion and the total loss of vehicle and payload will have far reaching consequences for not just SpaceX and the commercial satellite provider, but also NASA, the US military, and every other customer under a launch contact with the aerospace firm.
Here’s my interview with the BBC TV news a short while ago. Note that the cause is under investigation:
SpaceX is also trying to recover and recycle the Falcon 9 first stage.
Indeed as I reported just 2 days ago, SpaceX announce a contract with SES to fly the SES-10 communications satellite on a recycled Falcon 9.
This explosion will set back that effort and force a halt to all SpaceX launches until the root cause is determined.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.
CAPE CANAVERAL, FL — The telecommunications giant SES is boldly going where no company has gone before by making history in inking a deal today, Aug. 30, to fly the expensive SES-10 commercial satellite on the first ever launch of a ‘Flight-Proven’SpaceX booster – that’s been used and recovered.
Luxembourg-based SES and Hawthrone, CA-based SpaceX today jointly announced the agreement to “launch SES-10 on a flight-proven Falcon 9 orbital rocket booster” before the end of this year.
“The satellite, which will be in a geostationary orbit and expand SES’s capabilities across Latin America, is scheduled for launch in Q4 2016. SES-10 will be the first-ever satellite to launch on a SpaceX flight-proven rocket booster,” according to a joint statement.
That first launch of a flight-proven Falcon 9 first stage will use the CRS-8 booster that delivered a SpaceX Dragon to the International Space Station in April 2016. The reflight could happen as soon as October 2016.
The deal marks a major milestone and turning point in SpaceX CEO and billionaire founder Elon Musk’s long sought endeavor to turn the science fictionesque quest of rocket reusability into the scientific fact of reality.
“Thanks for the longstanding faith in SpaceX,” tweeted SpaceX CEO Elon Musk after today’s joint SES/SpaceX announcement.
“We very much look forward to doing this milestone flight with you.”
Elon Musk’s goal is to radically slash the cost of launching rockets and access to space via rocket recycling – in a way that will one day lead to his vision of a ‘City on Mars.’
Over just the past 8 months, SpaceX has successfully recovered 6 of the firms Falcon 9 first stage boosters intact – by land and by sea since December 2015 – in hopes of recycling and reusing them with new payloads from paying customers daring enough to take the risk of stepping into the unknown!
SES is that daring company and has repeatedly shown faith in SpaceX. They were the first commercial satellite operator to launch with SpaceX with SES-8 back in October 2013. Earlier this year the firm also launched SES-9 on the recently upgraded full thrust version of Falcon 9 in March 2016.
“Having been the first commercial satellite operator to launch with SpaceX back in 2013, we are excited to once again be the first customer to launch on SpaceX’s first ever mission using a flight-proven rocket. We believe reusable rockets will open up a new era of spaceflight, and make access to space more efficient in terms of cost and manifest management,” said Martin Halliwell, Chief Technology Officer at SES, in the statement.
“This new agreement reached with SpaceX once again illustrates the faith we have in their technical and operational expertise. The due diligence the SpaceX team has demonstrated throughout the design and testing of the SES-10 mission launch vehicle gives us full confidence that SpaceX is capable of launching our first SES satellite dedicated to Latin America into space.”
But the company first has to prove that the used vehicle can survive the extreme and unforgiving stresses of the violent spaceflight environment before they can relaunch it. So they have been carefully inspecting it for structural integrity, checking all the booster systems, plumbing, avionics, etc and retesting the first stage Merlin 1D engines.
Multiple full duration hot fire tests of the fully integrated booster have been conducted at the SpaceX test facility in McGregor, Texas as part of long life endurance testing. This includes igniting all nine used first stage Merlin 1D engines housed at the base of a landed rocket for approximately three minutes.
For the SES-10 launch, SpaceX plans to use the Falcon 9 booster that landed on an ocean going drone ship from NASA’s CRS-8 space station mission launched in April 2016, said Hans Koenigsmann, SpaceX vice president of Flight Reliability, to reporters recently at the Kennedy Space Center during NASA’s CRS-9 cargo launch to the ISS.
SpaceX has derived many lessons learned on how to maximize the chances for a successful rocket recovery, Koenigsmann explained to Universe Today at KSC when I asked for some insight.
“We learned a lot … from the landings,” Hans Koenigsmann, SpaceX vice president of Flight Reliability, told Universe Today during the media briefings for the SpaceX CRS-9 space station cargo resupply launch on July 18.
“There are no structural changes first of all.”
“The key thing is to protect the engines- and make sure that they start up well [in space during reentry],” Koenigsmann elaborated, while they are in flight and “during reentry.”
“And in particular the hot trajectory, so to speak, like the ones that comes in after a fast payload, like the geo-transfer payload basically.”
“Those engines need to be protected so that they start up in the proper way. That’s something that we learned.”
The SpaceX Falcon 9 first stage is outfitted with four landing legs at the base and four grid fins at the top to conduct the landing attempts.
“In general I think the landing concept with the legs, and the number of burns and the way we perform those seems to work OK,” Koenigsmann told me.
“Re-launching a rocket that has already delivered spacecraft to orbit is an important milestone on the path to complete and rapid reusability,” said Gwynne Shotwell, President and Chief Operating Officer of SpaceX.
“SES has been a strong supporter of SpaceX’s approach to reusability over the years and we’re delighted that the first launch of a flight-proven rocket will carry SES-10.”
How much money will SES save by using a spent, recycled first stage Falcon 9 booster?
SpaceX says the price of a completely new Falcon 9 booster is approximately $60 million.
Shotwell has said SpaceX will reduce the cost about 30%. So SES might be saving around $20 million – but there are no published numbers regarding this particular launch contract.
SES-10 will be the first SES satellite wholly dedicated to Latin America.
“The satellite will provide coverage over Mexico, serve the Spanish speaking South America in one single beam, and cover Brazil with the ability to support off-shore oil and gas exploration,” according to SES.
It will replace capacity currently provided by two other satellites, namely AMC-3 and AMC-4, and will “provide enhanced coverage and significant capacity expansion over Latin America – including Mexico, Central America, South America and the Caribbean. The high-powered, tailored and flexible beams will provide direct-to-home broadcasting, enterprise and mobility services.”
It is equipped with a Ku-band payload of 55 36MHz transponder equivalents, of which 27 are incremental. It will be stationed at 67 degrees West.
SES-10 was built by Airbus Defence and Space and is based on the Eurostar E3000 platform. Notably it will use “an electric plasma propulsion system for on-orbit manoeuvres and a chemical system for initial orbit raising and some on-orbit manoeuvres.”
The most recent SpaceX Falcon 9 booster to be recovered followed the dramatic overnight launch of the Japanese JCSAT-16 telecom satellite on Aug. 14.
It was towed back into port on atop the diminutive OCISLY ocean landing platform that measures only about 170 ft × 300 ft (52 m × 91 m). SpaceX formally dubs it an ‘Autonomous Spaceport Drone Ship’ or ASDS.
The 6 successful Falcon upright first stage landings are part of a continuing series of SpaceX technological marvels/miracles rocking the space industry to its core.
SpaceX had already successfully recovered first stages three times in a row at sea earlier this year on the ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27, prior to JCSAT-16 on Aug. 14.
Two land landings back at Cape Canaveral Landing Zone-1 were accomplished on Dec. 21, 2015 and July 18, 2016.

A SpaceX commercial Dragon cargo ship returned to Earth today, Friday, Aug. 26, 2016, by splashing down safely in the Pacific Ocean – thus concluding more than a month long stay at the International Space Station (ISS). The vessel was jam packed with some 1.5 tons of NASA cargo and critical science samples for eagerly waiting researchers.
The parachute assisted splashdown of the Dragon CRS-9 cargo freighter took place at 11:47 a.m. EDT today in the Pacific Ocean – located some 326 miles (520 kilometers) southwest of Baja California.
Dragon departed after spending more than five weeks berthed at the ISS.
It was loaded with more than 3,000 pounds of NASA cargo and critical research samples and technology demonstration samples accumulated by the rotating six person crews of astronauts and cosmonauts living and working aboard the orbiting research laboratory.
It arrived at the station on July 20 ferrying over 2.5 tons of priceless research equipment, gear, spare parts and supplies, food, water and clothing for the station’s resident astronauts and cosmonauts as well as the first of two international docking adapters (IDAs) in its unpressurized cargo hold known as the “trunk.”
The SpaceX Falcon 9 blasted off at 12:45 a.m. EDT July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and successfully delivered the Dragon CRS-9 resupply ship to its preliminary orbit about 10 minutes later.
SpaceX also successfully executed a spellbinding ground landing of the Falcon 9 first stage back at Cape Canaveral Air Force Station’s Landing Zone 1, located a few miles south of launch pad 40.
The dramatic ground landing of the 156 foot tall Falcon 9 first stage at LZ -1 took place about 9 minutes after liftoff. It marked only the second time a spent, orbit class booster has touched down intact and upright on land.
The stage was set for today’s return to Earth when ground controllers robotically detached Dragon from the Earth-facing port of the Harmony module early this morning using the station’s 57.7-foot (17.6-meter) long Canadian-built robotic arm.
Expedition 48 Flight Engineers Kate Rubins of NASA and Takuya Onishi of the Japan Aerospace Exploration Agency (JAXA) then used Canadarm 2 to release Dragon from the grappling snares at about 6:10 a.m. EDT (1011 GMT) this morning.
“Houston, station, on Space to Ground Two, Dragon depart successfully commanded,” radioed Rubins.
The ISS was soaring some 250 miles over the Timor Sea, north of Australia.
“Congratulations to the entire team on the successful release of the Dragon. And thank you very much for bringing all the science, and all the important payloads, and all the important cargo to the station,” Onishi said. “We feel really sad to see it go because we had a great time and enjoyed working on all the science that the Dragon brought to us.”
Dragon then backed away and moved to a safe distance from the station via a trio of burns using its Draco maneuvering thrusters.
The de-orbit burn was conducted at 10:56 a.m. EDT (1456 GMT) to drop Dragon out of orbit and start the descent back to Earth.
SpaceX contracted recovery crews hauled Dragon aboard the recovery ship and are transporting it to a port near Los Angeles, where some time critical cargo items and research samples will be removed and returned to NASA for immediate processing.
SpaceX plans to move Dragon back to the firms test facility in McGregor, Texas, for further processing and to remove the remaining cargo cache.
Among the wealth of over 3900 pounds (1790 kg) of research investigations loaded on board Dragon was an off the shelf instrument designed to perform the first-ever DNA sequencing in space and the first international docking adapter (IDA) that is absolutely essential for docking of the SpaceX and Boeing built human spaceflight taxis that will ferry our astronauts to the International Space Station (ISS) in some 18 months.
During a spacewalk last week on Aug. 19, the initial docking adapter known as International Docking Adapter-2 (IDA-2) was installed Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins of NASA.
Other science experiments on board included OsteoOmics to test if magnetic levitation can accurately simulate microgravity to study different types of bone cells and contribute to treatments for diseases like osteoporosis, a Phase Change Heat Exchanger to test temperature control technology in space, the Heart Cells experiments that will culture heart cells on the station to study how microgravity changes the human heart, new and more efficient three-dimensional solar cells, and new marine vessel tracking hardware known as the Automatic Identification System (AIS) that will aid in locating and identifying commercial ships across the globe.
The ring shaped IDA-2 unit was stowed in the Dragon’s unpressurized truck section. It weighs 1029 lbs (467 kg), measures about 42 inches tall and sports an inside diameter of 63 inches in diameter – so astronauts and cargo can easily float through. The outer diameter measures about 94 inches.
“Outfitted with a host of sensors and systems, the adapter is built so spacecraft systems can automatically perform all the steps of rendezvous and dock with the station without input from the astronauts. Manual backup systems will be in place on the spacecraft to allow the crew to take over steering duties, if needed,” says NASA.
“It’s a passive system which means it doesn’t take any action by the crew to allow docking to happen and I think that’s really the key,” said David Clemen Boeing’s director of Development/Modifications for the space station.
“Spacecraft flying to the station will use the sensors on the IDA to track to and help the spacecraft’s navigation system steer the spacecraft to a safe docking without astronaut involvement.”
CRS-9 counts as the company’s ninth of 26 scheduled flight to deliver supplies, science experiments and technology demonstrations to the International Space Station (ISS).
The CRS-9 mission was launched for the crews of Expeditions 48 and 49 to support dozens of the approximately 250 science and research investigations in progress under NASA’s Commercial Resupply Services (CRS) contract.

Setting foot on a distant planet… we’ve all dreamed about it at one time or another. And it has been a staple of science fiction for almost a century. Engage the warp dive, spool up the FLT, open a wormhole, or jump into the cryochamber. Next stop, Alpha Centauri (or some other star)! But when it comes to turning science fiction into science fact, there are certain unfortunate realities we have to contend with. For starters, none of the technology for faster-than-light travel exists!
Second, sending crewed mission to even the nearest planets is a very expensive and time consuming endeavor. But thanks to ongoing developments in the fields of miniaturization, electronics and direct-energy, it might be possible to send tiny spacecraft to distant stars in a single lifetime, which could carry something of humanity along with them. Such is the hope of Professor Philip Lubin and Travis Bradshears, the founders of “Voices of Humanity“.
For people familiar with directed-energy concepts, the name Philip Lubin should definitely ring a bell. A professor from the University of California, Santa Barbara (UCSB), he is also the mind behind the NASA-funded Directed Energy Propulsion for Interstellar Exploraiton (DEEP-IN) project, and the Directed Energy Interstellar Study. These projects seek to use laser arrays and large sails to achieve relativistic flight for the sake of making interstellar missions a reality.
Looking beyond propulsion and into the realm of public participation in space exploration, Prof. Lubin and Bradshears (an engineering and physics student from the University of California, Berkeley) came together to launch Voices of Humanity (VoH) in 2015. Inspired by their work with NASA, this Kickstarter campaign aims to create the world’s first “Space Time Capsule”.
Intrinsic to this is the creation of a Humanity Chip, a custom semiconductor memory device that can be attached to the small, wafer-scale spacecraft that are part of DEEP-IN and other directed-energy concepts. This chip will contain volumes of data, including tweets, media files, and even the digital DNA records of all those who want to take part in the mission. As Professor Lubin told Universe Today in a phone interview:
“We wanted to put on board some part of humanity. We couldn’t shrink ray people down, so Travis and I brainstormed and thought that the next best thing would be to allow people to become digital astronauts. We wanted to pave the way for interstellar missions where we could send the essence of humanity to the stars – “Emissaries of the Earth”, if you will. We wanted to pave the way for that.”
This digital archive would be similar to the Golden Record that was placed on the Voyager probes, but would be much more sophisticated. Taking advantage of all the advances made in computing, electronics and data storage in recent decades, it would contain many millions of times the data, but comprise a tiny fraction of the volume.
In fact, as Lupin explained, the state of technology today allows us to create a digital archive that would be about the same size a fingernail, and which would require no more than a single gram of mass to be allocated on a silicon wafer-ship. And while such a device is not the same as sending astronauts on interstellar voyages to explore other planets, it does allow humanity to send something of itself.
“We now have the technology to put a message from everyone on Earth onto a small piece of a tiny spacecraft,” said Lupin. “We want to begin today, and not just for the future, by putting information onto anything that is launched from Earth. We are the point technologically, at this moment, that we could put a small portion of humanity on this spacecraft.”
In essence, human beings would be able to create the interstellar equivalent of a “Baby on Board” sticker, except for humanity instead. This sticker would be no larger than a postage stamp, and could be mounted on every craft to leave Earth in the near future. In essence, all missions departing from Earth could have “Humanity on Board”.
The plan is to launch their first chip – Humanity Chip 1.0 – into Low Earth Orbit (LEO) in 2017. This will be followed by the creation of Humanity Chip 2.0, which take advantage of the developments that will have occurred by next year. Eventually, they hope that Humanity Chips will be a part of missions that increase in distance from Earth, eventually culminating in a mission to interstellar space.
While there are no deep-space missions ready to go just yet, several concepts are on the table for interplanetary missions that will rely on wafer-scale spacecraft (like NASA’s DEEP-IN concept). If their Kickstarter campaign succeeds in raising the $30,000 necessary to create a Humanity Chip, Prof. Lubin and Bradshears also hope to create a “Black Hole Chip”, where participants will be able to record their “less than happy” thoughts as part of the data, which will then be sent off into space forever.
They also have a stretch goal in mind, known as the “Beam Me Up” objective. In the event that their campaign is able to raise $100,000, they will use the funds to create a ground-based laser array that will beam a package of encoded data towards a target destination in space.
As of the penning of this article, Prof. Lubin and Bradshears have raised a total of $5,656 towards their goal of $30,000. The campaign kicked off earlier this month and will remain open for another 22 days. So if you’re interested in contributing to Humanity Chip 1.0, or becoming an “Emissary of the Earth”, there’s still plenty of time.
In addition to his work with NASA, Prof. Lubin is also responsible for the UCSB’s Directed Energy System for Targeting of Asteroids and ExploRation (DE-STAR) project, a proposed system that would use directed energy (i.e. big lasers!) to deflect asteroids, comets, and other near-Earth objects (NEOs) that could pose a risk to planet Earth.
And, in a recent article titled “The Search for Directed Intelligence“- which appeared in the March 2016 issue of REACH – Reviews in Human Space Exploration – Lupin indicated that advances in directed-energy applications might also help in the search for extra-terrestrial intelligence. Essentially, by looking for for sources of directed energy systems, he claims, we might be able to find our way to other civilizations.
It is an exciting age, where advances in telecommunications and electronics are allowing us to overcome the vast distances involved in space travel. In the future, astronauts may rely on robotic explorers and fast-as-light communications to explore distant worlds (a process known as telexploration). And with a digital archive on board, we will be able to send personal greetings to any life that may already exist there.
For those who would say “sharing personal information with extra-terrestrials is a bad idea”, I would remind them that they (probably) don’t have access to Twitter or our financial records. All the same, it might be wise not to include your Social Security (or Social Insurance) number in the recordings, or any other personal data you wouldn’t share with strangers!
And who knows? Someday, we may start colonizing other planets by sending our DNA there direct. The truth is always stranger than fiction, after all!

CAPE CANAVERAL AIR FORCE STATION, FL — Shortly after midnight today, Sunday, Aug. 14, and under near pristine Florida Space Coast skies, SpaceX dazzled its commercial customers and space enthusiasts alike worldwide with the twin feats of nailing the nighttime launch of the firm’s Falcon 9 carrying a huge Japanese telecommunications satellite to orbit and accomplishing the nailbiting precision touchdown of the first stage on a miniscule droneship at sea.
A virgin SpaceX Falcon 9 rocket carrying the JCSAT-16 telecom satellite roared to life right on time Sunday morning at 1:26 a.m. from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida and streaked to orbit.
Scarcely some nine minutes later the 15 story tall first stage completed a pinpoint and upright soft landing on a prepositioned ocean going platform after carrying the Japanese satellite to its intended Geostationary Transfer Orbit (GTO).
The satellite was launched using the upgraded version of the 229 foot tall Falcon 9 rocket. The first stage generates over 1.71 million pounds of sea level thrust when all nine Merlin 1D engines fire up on the pad.
Check out the expanding gallery of launch photos and videos.
The JCSAT-16 communications satellite was built by Space Systems Loral for Tokyo-based SKY Perfect JSAT Corp. It is equipped Ku-band and Ka-band communications services for customers of SKY Perfect JSAT Corp.
SKY Perfect JSAT Corp. ia a leading satellite operator in the Asia – Pacific region. JCSAT-16 will be positioned 22,300 miles (35,800 kilometers) above the equator.
Sunday’s launch was the second this year for The sextet of intact and upright landings of the recovered 156-foot-tall (47-meter) booster count as stunning successes towards SpaceX founder and CEO Elon Musk’s vision of rocket reusability and radically slashing the cost of sending rockets to space by recovering the boosters and eventually reflying them with new payloads from paying customers.
The JCSAT-14 satellite was already successfully launched earlier this year atop a SpaceX Falcon 9 on May 6.
JCSAT-16 will primarily serve as an on orbit back up spare for the company’s existing services, a company spokeswomen told Universe Today at the media launch viewing site.
The U.S. Air Force’s 45th Space Wing supported SpaceX’s Falcon 9 launch of JCSAT-16.
“I am very proud of the entire Space Coast team. Their flawless work made this mission a success,” said Col. Walt Jackim, 45th Space Wing vice commander and mission Launch Decision Authority.
“Assured access to space remains a difficult and challenging endeavor. Today’s launch reflects a superb collaborative effort between commercial launch providers, allied customers, and U.S. Air Force range and safety resources. The 45th Space Wing remains a proud member of the Space Coast team and we look forward to continuing our service as the ‘World’s Premier Gateway to Space.”
With today’s event, SpaceX has now successfully soft landed 6 of the spent first stage boosters over the past eight months following successful rocket delivery launches to orbit for NASA and commercial customers – two on land and four at sea.

KENNEDY SPACE CENTER, FL – Scarcely three weeks after the mesmerizing midnight launch and landing of a SpaceX Falcon 9 rocket that delivered over two tons of science and critical hardware to the space station for NASA, the innovative firm is set to repeat the back to back space feats – with a few big twists – during a post midnight launch this Sunday, Aug.14 of a Japanese telecom satellite.
In less than 24 hours, a freshly built SpaceX Falcon 9 is set to transform night into day and launch the JCSAT-16 communications satellite from Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida.
And some nine minutes later, the 15 story Falcon 9 first stage is scheduled to make a pinpoint soft landing on a tiny, prepositioned drone ship at sea in the vast Atlantic Ocean.
To date SpaceX has successfully soft landed 5 first stage boosters over the past eight months – two by land and three by sea.
Nighttime liftoffs are always a viewing favorite among the general public – whether visiting from near or far. And this one is virtually certain to offer some spectacular summer fireworks since the weather looks rather promising – if all goes well.
Sunday’s launch window opens at 1:26 a.m. EDT and extends two hours long for the 229 foot tall Falcon 9 rocket. The window closes at 3:26 a.m. EDT.
The commercial mission involves lofting the JCSAT-16 Japanese communications satellite to a Geostationary Transfer Orbit (GTO) for SKY Perfect JSAT – a leading satellite operator in the Asia – Pacific region. JCSAT-16 will be positioned 22,300 miles (35,800 kilometers) above the equator.
Sunday’s launch is the second this year for SKY Perfect JSAT. The JCSAT-14 satellite was already launched earlier this year on May 6.
You can watch the launch live via a special live webcast from SpaceX.
The SpaceX webcast will be available starting at about 20 minutes before liftoff, at approximately 1:06 a.m. EDT at SpaceX.com/webcast
The weather currently looks very good. Air Force meteorologists are predicting an 80 percent chance of favorable weather conditions at launch time in the wee hours early Sunday morning.
The primate concerns are for violations of the Cumulus Cloud and Think Cloud rules.
The U.S. Air Force’s 45th Space Wing will support SpaceX’s Falcon 9 launch of JCSAT-16.
In cases of any delays for technical or weather issues, a backup launch opportunity exists 24 hours later on Monday morning with a 70 percent chance of favorable weather.
The rocket has already been rolled out to the launch pad on the transporter and raised to its vertical position.
The path to launch was cleared following the successful Aug. 10 hold down static fire test of the Falcon 9 first stage Merlin 1-D engines. SpaceX routinely performs the hot fire test to ensure the rocket is ready.
Watch this crystal clear video of the Static Fire Test from USLaunchReport:

Via a fleet of 15 satellites, Tokyo, Japan based SKY Perfect JSAT provides high quality satellite communications to its customers.
The JCSAT-16 communications satellite was designed and manufactured by Space Systems/Loral for SKY Perfect JSAT Corporation.
JCSAT-16 satellite will separate from the second stage and will be deployed about 32 minutes after liftoff from Cape Canaveral. The staging events are usually broadcast live by SpaceX via stunning imagery from onboard video cameras.
A secondary objective is to try and recover the first stage booster via a propulsive landing on an ocean-going platform.
This booster is again equipped with 4 landing legs and 4 grid fins.
Following stage separation, SpaceX will try to soft land the first stage on the “Of Course I Still Love You” drone ship positioned about 400 miles (650 km) off shore of Florida’s east coast in the Atlantic Ocean.
But SpaceX officials say landings from GTO mission destinations are extremely challenging because the first stage will be subject to extreme velocities and re-entry heating.
If all goes well with the supersonic retropropulsion landing on the barge, the booster will arrive back into Port Canaveral a few days later.
To date SpaceX has successfully recovered first stages three times in a row at sea this year on the an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.

KENNEDY SPACE CENTER, FL – SpaceX founder Elon Musk’s daring dream of rocket recycling and reusability is getting closer and closer to reality with each passing day. After a breathtaking series of experimental flight tests aimed at safely landing the firms spent Falcon 9 first stages on land and at sea over the past half year the bold effort achieved another major milestone by just completing the first full duration test firing of one of those landed boosters.
On Thursday, July 28, SpaceX engineers successful conducted a full duration static engine test firing of the 156-foot-tall (47-meter) recovered Falcon 9 first stage booster while held down on a test stand at the company’s rocket development test facility in McGregor, Texas. The engines fired up for about two and a half minutes.
The SpaceX team has been perfecting the landing techniques by adopting lessons learned after each landing campaign attempt.
What are the lessons learned so far from the first stage landings and especially the hard landings? Are there any changes being made to the booster structure? How well did the landing burn scenario perform?
During SpaceX’s recent CRS-9 launch campaign media briefings at NASA’s Kennedy Space Center on July 18, I asked SpaceX VP Hans Koenigsmann for some insight.
“We learned a lot … from the landings,” Hans Koenigsmann, SpaceX vice president of Flight Reliability, told Universe Today during the recent media briefings for the SpaceX CRS-9 space station cargo resupply launch on July 18.
“There are no structural changes first of all.”
“The key thing is to protect the engines,” Koenigsmann elaborated, while they are in flight and “during reentry”.
The SpaceX Falcon 9 first stage is outfitted with four landing legs at the base and four grid fins at the top to conduct the landing attempts.
“In general I think the landing concept with the legs, and the number of burns and the way we perform those seems to work OK,” Koenigsmann told Universe Today.
After separating from the second stage at hypersonic speeds of up to some 4000 mph, the first stage engines are reignited to reverse course and do a boost backburn back to the landing site and slow the rocket down for a soft landing, via supersonic retropulsion.
Proper engine performance is critical to enabling a successful touchdown.
“The key thing is to protect the engines – and make sure that they start up well [in space during reentry],” Koenigsmann explained. “And in particular the hot trajectory, so to speak, like the ones that comes in after a fast payload, like the geo-transfer payload basically.”
“Those engines need to be protected so that they start up in the proper way. That’s something that we learned.”
Elon Musk’s goal is to radically slash the cost of launching rockets and access to space via rocket reuse – in a way that will one day lead to his vision of a ‘City on Mars.’
SpaceX hopes to refly a once flown booster later this year, sometime in the Fall, using the ocean landed Falcon from NASA’s CRS-8 space station mission launched in April, says Koenigsmann.
But the company first has to prove that the used vehicle can survive the extreme and unforgiving stresses of the violent spaceflight environment before they can relaunch it.
The July 28 test firing is part of that long life endurance testing and involved igniting all nine used first stage Merlin 1D engines housed at the base of a used landed rocket.
The Falcon 9 first stage generates over 1.71 million pounds of thrust when all nine Merlin engines fire up on the test stand for a duration of up to three minutes – the same as for an actual launch.
Watch the engine test in this SpaceX video:

Just 10 minutes after launching the JCSAT-14 telecom satellite to a Geostationary Transfer Orbit (GTO), the used first stage relit a first stage Merlin 1D engine.
It conducted a series of three recovery burns to maneuver the rocket to a designated landing spot at sea or on land and rapidly decelerate it from supersonic speeds for a propulsive soft landing, intact and upright using a quartet of landing legs that deploy in the final moments before a slow speed touchdown.
However, although the landing was upright and intact, this particular landing was also classed as a ‘hard landing’ because the booster landed at a higher velocity and Merlin 1D first stage engines did sustain heavy damage as seen in up close photos and acknowledged by Musk.
“Most recent rocket took max damage, due to v high entry velocity. Will be our life leader for ground tests to confirm others are good,” Musk tweeted at the time.
Nevertheless it all worked out spectacularly and this was the first one to be recovered from the much more demanding, high velocity trajectory delivering a satellite to GTO.
Indeed prior to liftoff, Musk had openly doubted a successful landing outcome, since this first stage was flying faster and at a higher altitude at the time of separation from the second stage and thus was much more difficult to slow down and maneuver back to the ocean based platform compared to ISS missions, for example.
So although this one cannot be reflown, it still serves another great purpose for engineers seeking to determining the longevity of the booster and its various components – as now audaciously demonstrated by the July 28 engine test stand firing.
“We learned a lot even on the missions where things go wrong with the landing, everything goes well on the main mission of course,” said Koenigsmann.
Altogether SpaceX has successfully soft landed and recovered five of their first stage Falcon 9 boosters intact and upright since the history making first ever land landing took place just seven months ago in December 2015 at Cape Canaveral Air Force Station in Florida.
See the stupendous events unfold in up close photos and videos herein.
Following each Falcon 9 launch and landing attempt, SpaceX engineers assess the voluminous and priceless data gathered, analyze the outcome and adopt the lessons learned.
CRS-9 marks only the second time SpaceX has attempted a land landing of the 15 story tall first stage booster back at Cape Canaveral Air Force Station – at the location called Landing Zone 1 (LZ 1).
Watch this exquisitely detailed up close video showing the CRS-9 first stage landing at LZ 1, as shot by space colleague Jeff Seibert from the ITL causeway at CCAFS- which dramatically concluded with multiple shockingly loud sonic booms rocketing across the Space Coast and far beyond and waking hordes of sleepers:

The history making first ever ground landing successfully took place at Landing Zone 1 (LZ 1) on Dec. 22, 2015 as part of the ORBCOMM-2 mission. Landing Zone 1 is built on the former site of Space Launch Complex 13, a U.S. Air Force rocket and missile testing range.
SpaceX also successfully recovered first stages three times in a row at sea this year on an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.
OCISLY is generally stationed approximately 400 miles (650 kilometers) off shore and east of Cape Canaveral, Florida in the Atlantic Ocean. The barge arrives back in port at Port Canaveral several days after the landing, depending on many factors like weather, port permission and the state of the rocket.
The rocket apparently ran out of liquid oxygen fuel in the final moments before touchdown, hit hard, tipped over and pancaked onto the deck.
“Looks like early liquid oxygen depletion caused engine shutdown just above the deck,” Musk explained via twitter at the time.
“Looks like thrust was low on 1 of 3 landing engines. High g landings v sensitive to all engines operating at max.”
“We learned a lot even on the mission where things go wrong with the landing,” Koenigsmann explained. “Everything goes well on the main mission of course.”
“That’s actually something where you have successful deploy and the landing doesn’t quite work- and yet its the landing that gets all the attention.”
“But even on those landings we learned a lot. In particular on the last landing [from Eutelsat launch] we learned a lot.”
“We believe we found a way to operationally protect these engines and to make it safer for them to start up – and to come up to full thrust and stay at full thrust.”
What exactly does “protecting the engines” mean “in flight?”
“Yes I mean protecting the engines during reentry,” Koenigsmann told me.
“That’s when the engines get hot. We enter with the engines facing the flow. So its basically the engines directly exposed to the hot flow. And that’s when you need to protect the engines and the gases and liquids that are in the engines. To make sure that nothing boils off and does funny things.”
“So all in all these series of drone ship landings has been extremely successful, even when we didn’t recover all the first stages [fully intact].”

KENNEDY SPACE CENTER, FL – In a breathtaking feat mesmerizing hordes of thrilled spectators, SpaceX nailed today’s (July 18) back to back post midnight launch and landing of the firms Falcon 9 first stage tasked to carry a cargo Dragon loaded with over two tons of critical science, supplies and a crew docking port to the space station for NASA.
Liftoff of the SpaceX Falcon 9 rocket in its upgraded, full thrust version and the Dragon CRS-9 resupply ship took place right on time at 12:45 a.m. EDT Monday, July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
SpaceX simultaneously successfully delivered over 5000 pounds (2200 kg) of research supplies to orbit for NASA in a commercial cargo Dragon ship, as the primary mission goal – and soft landed the approximately 60,000 pound Falcon 9 first stage on land, as the experimental secondary mission goal.
“The Falcon 9 first stage we landed is in excellent shape,” Hans Koenigsmann, SpaceX vice president of Flight Reliability, told Universe Today at the 2 a.m. EDT post launch and landing media briefing early this morning.
See my launch and landing streak shot and photos herein, including deployment of the four landing legs in the final seconds before propulsive touchdown.
The twin accomplishments will have far reaching implications for the exploration and exploitation of space for all humanity.
“Each commercial resupply flight to the space station is a significant event. Everything, from the science to the spare hardware and crew supplies, is vital for sustaining our mission,” said Kirk Shireman, NASA’s International Space Station Program manager.
“With equipment to enable novel experiments never attempted before in space, and an international docking adapter vital to the future of U.S. commercial crew spacecraft, we’re thrilled this Dragon has successfully taken flight.”
The CRS-9 mission is to support the resident six-person crew of men and women currently working on the station from the US, Russia and Japan.
The propulsive soft landing of the 156 foot tall Falcon 9 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 40.
The dramatic ground landing at LZ -1 took place about 9 minutes after liftoff.
The first and second stages separated about two and a half minutes after liftoff and were easily visible to any eyewitness watching – backdropped by the sunshine states dark skies.
As the second stage soared to orbit, the first stage reignited a first stage engine for a series of burns targeting a return to the Cape.
We spotted the first engine firing about two mintues before landing, as it descended directly overhead of myself and everyone in the Cape Canaveral region.
For a few moments it looked like it was headed right towards us, but then steered away as planned with engines blazing to slow the boosters descent to make a gentle landing at LZ-1.
Finally the Falcon landed, obscured by a big vapor cloud and sonic booms roaring around the space coast – and waking many local residents. Several folks told me they were suddenly woken by the shocking booms reverberating inside their homes.
Some area residents even called 911 not knowing the true nature of the noises.
Among the wealth of over 3900 pounds (1790 kg) of research investigations loaded on board Dragon is an off the shelf instrument designed to perform the first-ever DNA sequencing in space, and the first international docking adapter (IDA) that is absolutely essential for docking of the SpaceX and Boeing built human spaceflight taxis that will ferry our astronauts to the International Space Station (ISS) in some 18 months.
CRS-9 counts as the company’s ninth scheduled flight to deliver supplies, science experiments and technology demonstrations to the International Space Station (ISS).
The CRS-9 mission is for the crews of Expeditions 48 and 49 to support dozens of the approximately 250 science and research investigations in progress under NASA’s Commercial Resupply Services (CRS) contract.
Dragon reached its preliminary orbit about 10 minutes after launch. Then it deployed a pair of solar arrays and began a carefully choreographed series of thruster firings to reach the space station.
If all goes well, Dragon is scheduled to arrive at the orbiting outpost on Wednesday, July 20, after a 2 day orbital chase.
NASA astronaut Jeff Williams will then reach out with the station’s 57.7-foot-long Canadian-built robotic arm to grapple and capture the private Dragon cargo ship working from a robotics work station in the station’s cupola. NASA astronaut Kate Rubins will serve as Williams backup. She just arrived at the station last week on July 9 for a minimum 4 month stay, after launching to orbit on a Russian Soyuz on July 6 with two additional crew mates.
Ground commands will be sent from Houston to the station’s arm to install Dragon on the Earth-facing bottom side of the Harmony module for its stay at the space station. The crew expects to open the hatch a day later after pressurizing the vestibule in the forward bulkhead between the station and Dragon.
Live coverage of the rendezvous and capture July 20 will begin at 5:30 a.m. on NASA TV, with installation coverage set to begin at 9:45 a.m.
CRS-9 marks only the second time SpaceX has attempted a land landing of the 15 story tall first stage booster.

SpaceX also successfully recovered first stages three times in a row at sea this year on an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.
Altogether SpaceX has successfully landed and recovered 5 first stage booster intact and upright.

KENNEDY SPACE CENTER, FL – The outlook is outstanding for a dramatic midnight blastoff of the next SpaceX commercial cargo Dragon jam packed with some 5000 pounds of critical payloads and research supplies for NASA and heading to the space station on Monday, July 18 – that also simultaneously features an experimental land landing that promises to rock loudly across the Florida space coast and one day slash launch costs.
Dragon is carrying a crucial crew docking port absolutely essential for conducting future human space missions to the orbiting outpost as well as a host of wide ranging science experiments essential for NASA exploiting the space environment for research in low earth orbit and deep space exploration.
Liftoff of the SpaceX Falcon 9 rocket in its upgraded, full thrust version and the Dragon CRS-9 resupply ship is targeted for 12:45 a.m. EDT Monday, July 18, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
The CRS-9 mission is to support the resident six-person crew of men and women currently working on the station from the US, Russia and Japan.
Spectators are filling local area hotels in anticipation of a spectacular double whammy sky show comprising a thunderous nighttime launch streaking to orbit – followed minutes later by a brilliant rocket flash and night landing back at the Cape of the Falcon first stage that will send sonic booms roaring all around the coast and surrounding inland areas.
SpaceX has confirmed they are attempting the secondary mission 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 40.
The weather and technical outlook for the 229 foot-tall (70 meter) Falcon 9 looks fantastic at this time, a day before liftoff.
The official weather forecast from Air Force meteorologists with the 45th Space Wing calls for a 90 percent chance of “GO” with extremely favorable conditions at launch time for liftoff of this upgraded, SpaceX Falcon 9.
The only concerns are for Cumulus clouds building up and a chance of precipitation.
And for added stargazers delight the night sky features a full moon.
The SpaceX/Dragon CRS-9 launch coverage will be broadcast on NASA TV beginning at 11:30 p.m. EDT Sunday, July 17, with additional commentary on the NASA launch blog.
SpaceX will also feature their own live webcast beginning approximately 20 minutes before launch at 12:25 a.m. EDT Monday, July 18
The launch window is instantaneous, meaning that any delays due to weather or technical issues will results in a minimum 2 day postponement.
If the launch does not occur Monday, a backup launch opportunity exists on 12 a.m. Wednesday, July 20, just seconds after midnight, with NASA TV coverage starting at 10:45 p.m. EDT Tuesday, July 19.
CRS-9 marks only the second time SpaceX has attempted a land landing of the 15 story tall first stage booster.

SpaceX also successfully recovered first stages three times in a row at sea this year on an ocean going drone ship barge using the company’s OCISLY Autonomous Spaceport Drone Ship (ASDS) on April 8, May 6 and May 27.
SpaceX issued a statement describing how local area residents could hear sonic booms – similar to those heard during landings of NASA’s space shuttles.
“There is the possibility that residents of northern and central Brevard County, Fla. may hear one or more sonic booms during landing. A sonic boom is a brief thunder-like noise a person on the ground hears when an aircraft or other vehicle flies overhead faster than the speed of sound,” said SpaceX.
Who could be affected?
“Residents of the communities of Cape Canaveral, Cocoa, Cocoa Beach, Courtenay, Merritt Island, Mims, Port Canaveral, Port St. John, Rockledge, Scottsmoor, Sharpes, and Titusville in Brevard County, Fla. are most likely to hear a sonic boom, although what residents experience will depend on weather conditions and other factors.”
The sights and sound are certain to be thrilling- so catch it if you can!

The CRS-9 mission is for the crews of Expeditions 48 and 49 to support dozens of the approximately 250 science and research investigations in progress under NASA’s Commercial Resupply Services (CRS) contract.
SpaceX engineers conducted their standard static fire hold down test of the first stages Merlin 1D engines with the rocket erect at pad 40, this morning Saturday, July 16.
The customary test lasts a few seconds and was conducted with the Dragon bolted on top at about 9:30 a.m. I saw the test while visiting atop neighboring Launch Complex 39B at the Kennedy Space Center – see photo.
“All looks good,” reported Hans Koenigsmann, SpaceX vice president of Flight Reliability, at a media briefing this afternoon.
“We expect a GO for launch.”
Dragon will reach its preliminary orbit about 10 minutes after launch. Then it will deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.

Watch for Ken’s onsite CRS-9 mission reports direct from the Kennedy Space Center and Cape Canaveral Air Force Station, Florida.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.

The target date for the ‘Return to Flight’ launch of Antares on a cargo resupply mission for NASA to the International Space Station (ISS) is “likely to result in an updated launch schedule in the August timeframe,” Orbital ATK spokeswoman Sean Wilson told Universe Today.
The company had most recently been aiming towards an Antares launch date around July 6 from NASA’s Wallops Flight Facility – for its next NASA contracted mission to stock the ISS via the Orbital ATK Cygnus cargo freighter on a flight known as OA-5.
Meanwhile the firms most recently launched Cygnus OA-6 cargo ship departed the space station and completed its planned destructive reentry into the Earth’s atmosphere on Wednesday, June 22.
But before Orbital ATK can resume Antares/Cygnus cargo flights to the ISS, it had to successfully hurdle through a critically important milestone on the path to orbit – namely a static hot fire test of the significantly modified first stage to confirm that its qualified for launch.
To that end the aerospace firm recently completed a successful 30 second long test firing of the re-engined first stage on May 31 at Virginia Space’s Mid-Atlantic Regional Spaceport (MARS) Launch Pad 0A – as I reported here earlier.
A thorough analysis of the hot fire test results and its implications is underway.
“Our Antares team recently completed a successful stage test and is wrapping up the test data analysis,” Wilson said.
“Final trajectory shaping work is also currently underway, which is likely to result in an updated launch schedule in the August timeframe.”
In the meantime, company engineers continue to ready the rocket and payload.
“We are continuing to prepare for the upcoming launch of the Antares rocket and Cygnus spacecraft for the OA-5 cargo logistics mission to the International Space Station from NASA’s Wallops Flight Facility,” Wilson noted.
It’s also clear that a decision on a launch date target is some weeks away and depends on the busy upcoming manifest of other ISS missions coming and going.
“A final decision on the mission schedule, which takes into account the space station traffic schedule and cargo requirements, will be made in conjunction with NASA in the next several weeks.”
And it also must take into account the launch of the intervening SpaceX ISS cargo flight that was just postponed two days to no earlier than July 18.
Another factor is the delayed launch of the next manned crew on a Russian Soyuz capsule from late June into July. Blastoff of the three person crew from Russia, the US and Japan is set for July 7. OA-5 will deliver some 3 tons of science experiments and crew supplies.
As a direct result consequence of the catastrophic launch disaster, Orbital STK managers decided to outfit the Antares medium-class rocket with new first stage RD-181 engines built in Russia.
The RD-181 flight engines are built by Energomash in Russia and had to be successfully tested via the static hot fire test to ensure their readiness.
As a result of switching to the new RD-181 engines, the first stage also had to be modified to incorporate new thrust adapter structures, actuators, and propellant feed lines between the engines and core stage structure, Mike Pinkston, Orbital ATK General Manager and Vice President, Antares Program told me in a prior interview.
So the primary goal of the stage test was to confirm the effectiveness of the new engines and all the changes in the integrated rocket stage.
It’s not entirely clear at this time whether the Antares launch delay to August is due to changes in the ISS manifest scheduling or any lingering questions from the hot fire test or both.
“A final decision on the mission schedule definitely takes into account the completion of data analysis combined with the busy space station traffic schedule and NASA’s cargo requirements,” Wilson told me in a response requesting clarification.
Following a quick look immediately following the May 31 test, Orbital ATK officials initially reported that all seemed well, with the caveat that further data review is needed.
“Early indications show the upgraded propulsion system, core stage and launch complex all worked together as planned,” said Mike Pinkston, Orbital ATK General Manager and Vice President, Antares Program.
“Congratulations to the combined NASA, Orbital ATK and Virginia Space team on a successful test.”
Orbital ATK engineers will now “review test data over the next several days to confirm that all test parameters were met. ”
The test used the first stage core planned to launch the OA-7 mission from Wallops late this year.
With the engine test completed, the OA-7 stage will be rolled back to the HIF processing hanger at Wallops and a new stage fully integrated with the Cygnus cargo freighter will be rolled out to the pad for the OA-5 ‘Return to Flight’ mission in August.
The mission of the OA-6 Cygnus ended on Wednesday, with a planned destructive reentry into the Earth’s atmosphere at 9:29 a.m. EDT.
Also known as the SS Rick Husband, it had spent 3 months in orbit since launching in March on a ULA Atlas V.
It departed the ISS on June 14 and continued several science experiments. Most notable was to successfully create the largest fire in space via the Spacecraft Fire Experiment-I (Saffire-I).
