PORT CANAVERAL/KENNEDY SPACE CENTER, FL – ‘The SpaceX boosters back in town! The boosters back in town!’ paraphrasing the popular lyrics of the hit single from Irish hard rock band Thin Lizzy – its what comes to mind with the speedy cadence of ‘launch, land and relaunch’ firmly established by CEO Elon Musk’s hard rocking crew of mostly youthful rocket scientists and engineers.

Barely three days after successfully launching the commercial KoreaSat-5A telecomsat on Monday Oct 30, the SpaceX Falcon 9 first stage booster that did the heavy lifting to orbit generating 1.7 million pounds of liftoff thrust – arrived back in town Thursday, Nov. 2 or more specifically back into Port Canaveral, Florida.

“Guess who’s back in town?” – the song continues – well its the Falcon 9 that reached the edge of space on Halloween Eve while traveling several thousand miles per hour, flipped around like a witches broom and carried out a pinpoint propulsive and upright touchdown of what amounts to a stick on a board in the middle of the Atlantic Ocean. Just amazing!

Floating atop the football field sized platform upon which it soft landed 8.5 minutes after the two stage Falcon 9 lifted off at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The 16 story tall booster arrived back into the mouth of Port Canaveral late Thursday at sunset – as witnessed up close by myself and several space journalist colleagues.

Check out our expanding photo and video gallery compiled here of the boosters arrival into Port on the OCISLY droneship. The gallery is growing so check back again for more up close looks of the ocean arrival, sailing and docking.

Furthermore the four landing legs that made the landing sequence possible – have already been quickly detached by workers this afternoon, as shown here with additional incredible up close imagery.

Plus also featured are lots of imagery of the booster sailing through the narrow channel of Port Canaveral – often past seemingly oblivious spectators and pleasure craft who have no idea what they are seeing. As well as imagery of work crews processing the booster for the eventual return back onto base.

The 156 foot-tall first stage atop OCISLY was towed from the Atlantic Ocean landing zone located several hundred miles off shore of the Florida’s East coast back into Port Canaveral by a tugboat named “Hawk.”

The Hawk was accompanied by a small naval flotilla of commercial vessels SpaceX leased for the occasion.

In fact with each booster return the SpaceX technicians are progressing faster and faster carrying out the booster processing involving safing, cap and line attachment, leg removal, and lowering the booster for horizontal placement on a specially outfitted lengthy multi-wheeled trailer for hauling back to SpaceX hangar facilities on the Kennedy Space Center and Cape Canaveral Air Force Station.

After arriving in port, and sailing through the channel for about 45 minutes the SpaceX flotilla carefully and methodically edged the droneship closer to shore and docked the vessel last night – and the crews got a well deserved rest as the booster basked in the maritime glow producing beautiful water reflection vistas.

The team wasted no time this morning. At the crack of dawn they began the task of attaching a hoisting cap to the top of the first stage.

Shortly after 9 a.m. EDT they craned the booster off OCISLY and onto a restraining pedestal platform on land.

The techs were working fast and making mincemeat of the booster.

They detached the four insect like legs one after another in an operation that looked a lot like a well thought out dissection.

One at a fime over a period about roughly two hour the workers methodically unbolted and detached the legs in 2 pieces. First they they slung a harness around the upper strut and removed it with a small crane. Then they did the same with the lower foot pad.

Altogether the land leg amputation operation took about 2.5 hours.

The now legless Falcon 9 stands erect. It will soon be lowered and placed horizontally for transport back to the base.

It has been barely two weeks after the last dogeship landed booster arrived back into port in mid-October for the SES-11 launch on October 11 and sunrise port arrival on October 15.

OCISLY which stands for “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 30 launch and was prepositioned in the Atlantic Ocean several hundred miles (km) off the US East coast, awaiting the boosters 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.

KENNEDY SPACE CENTER, FL – With the stunningly beautiful Halloween eve liftoff of the commercial KoreaSat-5A telecomsat payload from the Florida Space Coast, SpaceX matched competitor United Launch Alliance’s (ULA) single year launch record of 16 missions – and the blastoff record breaker is on tap in just 2 weeks time!

In fact several additional Falcon 9 missions are planned before the end of 2017 that could bring the year’s accumulated total to an incredible 20 or more liftoffs – if all goes well from SpaceX’s coastal launch bases in Florida and California.

Hawthorne, Ca based SpaceX tied ULA’s 16 mission record on Monday, Oct. 30, when their Falcon 9 blasted off mid-afternoon carrying the private KoreaSat-5A telecomsat mission right on time at the opening of the launch window at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Check out the exciting gallery of SpaceX KoreaSat-5A launch imagery and videos compiled here from this author and several space media colleagues. And check back often as the gallery grows!

ULA established their one year record of 16 missions in 2009 with the launch of NASA’s Wide-field Infrared Survey Explorer (WISE) spacecraft by a Delta II on Dec. 14, 2009.

Altogether ULA’s 2009 launch manifest included five Atlas Vs, eight Delta IIs, two Delta IVs and the first Delta IV Heavy carrying an NRO payload.

ULA is a 50:50 joint venture owned by Boeing and Lockheed Martin – now in fierce competition with SpaceX founded by billionaire and CEO Elon Musk who has won numerous commercial, government and military contracts by dramatically slashing launch costs.

Adding to the drama of SpaceX’s record breaking next Falcon 9 launch is that it’s a secret mission planned for about Nov. 15 – and its codenamed ‘Zuma’ – – but about which we know basically nothing.
To date 12 of this year’s 16 Falcon 9’s have launched from Launch Complex 39A at the Kennedy Space Center, Fl.

After lying dormant for six years, Pad 39A has been repurposed and refurbished by SpaceX from its days as a NASA shuttle launch pad.

NASA’s last space shuttle launch took place in July 2011 with the STS-135 mission to the International Space Station.

In addition to being SpaceX’s 16th launch this year, KoreaSat-5A was the 2nd one by the new space firms Falcon 9 rocket from Florida’s Spaceport in October, and the third overall in October counting another liftoff from Vandenberg AFB, Calif. – thus maintaining an absolutely torrid launch pace on the way to the record tying mission.

Monday’s mission also marks the first for a Korean satellite customer.

The nearly two ton commercial KoreaSat-5A satellite will provide Direct to Home (DTH) broadcasting, maritime, internet and other services to the North Asian region centering around South Korea.

Koreasat-5A was built by prime contractor, Thales Alenia Space, responsible for the design, production, testing and ground delivery. It arrived at the Florida launch base on Oct. 5 for integration with the Falcon 9 rocket.

The 3,700 kg satellite is equipped with 36 Ku-band transponders and based on Thales Alenia Space’s new-generation Spacebus 4000B2 platform. It will replace Koreasat 5.

The solar panels provide a payload power of approximately 6.5 kW. It will be positioned at 113° East and provide coverage for Indochina, Japan, Korea, the Philippines and the Middle East including Direct to Home (DTH) services.

KENNEDY SPACE CENTER, FL – SpaceX delivered a spectacular Halloween eve delight with today’s Falcon 9 launch of a Korean HDTV satellite that lit up the Florida Space Coast skies with a glow that delighted kids of all ages and ghouls alike and put an end at last for today to the atrocious wet and windy weather afflicting the Spaceport region.

The SpaceX Falcon 9 blasted off mid-afternoon Monday Oct. 30 with the private KoreaSat-5A telecomsat mission right at the opening of the launch window at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

Eight and a half minutes after liftoff the 15 story tall first stage booster nailed another rocket assisted touchdown on the OCISLY droneship pre-positioned several hundred miles off shore of Cape Canaveral in the Atlantic Ocean.

Today’s mission marks the 16th launch by SpaceX this year, the 2nd this month by the new space firms Falcon 9 rocket from Florida’s Spaceport, and the third overall counting another liftoff from Vandenberg AFB, Calif. – thus maintaining an absolutely torrid and record setting yearly launch pace.

The launch was broadcast live on a SpaceX dedicated webcast.

Florida finally fulfilled its billing as the ‘Sunshine State’ with truly superb afternoon weather for Monday afternoon’s liftoff of a SpaceX Falcon 9 with its first Korean satellite customer – and the decent weather outlook looks like it will extend into Tuesdays Halloween trick or treating for the local kiddies and their imaginative costumes.

The two stage 229-foot-tall (70-meter-tall) Falcon 9 rocket shined at sunrise this morning and throughout the countdown and fueling process fed the falcon with RP-1 and liquid oxygen propellant powering the rockets nine first stage Merlin 1D engines.

Altogether the Merlin 1D engine delivered a powerful liftoff punch that was far more than a Halloween ‘boo’ as the engines ignited with 1.7 million pounds of liftoff thrust.

As the Falcon 9 roared off launch pad 39A a rumbling thunder reverberated across the space coast region and beyond that brought broad smiles of glee to spectators faces packing local area beaches and hotels and quickly dispatched wicked ghouls to their graves.

Trick or treaters will have a fine Halloween indeed following SpaceX’s thunderous rocket launch into picture perfect clear blue skies that were set of fire as the rocket vaulted off the pad and arched over eastwards to the African continent as it accelerated to the heavens.

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

Satellite deployment took place as planned 35 minutes after launch as seen on the webcast.

“Successful deployment of Koreasat-5A to geostationary transfer orbit confirmed,” said SpaceX.

The launch was also accompanied by a successful attempt to recover the 156 foot tall first stage booster after completing its primary satellite delivery mission task.

Choppy seas from Tropical Storm Phillipe made the sea landing even more challenging.

SpaceX engineers guided it to a landing on the tiny OCISLY drone ship for an upright and intact pinpoint soft landing touchdown on the ocean going platform prepositioned off shore in the Atlantic Ocean – some 8 minutes after blastoff.

OCISLY or “Of Course I Still Love You” left Port Canaveral several days ahead of the planned Oct. 30 launch and was prepositioned in the Atlantic Ocean several hundred miles (km) off the US East coast, awaiting the boosters approach and pinpoint propulsive soft landing.

“Falcon 9 first stage has landed on the Of Course I Still Love You droneship.” announced SpaceX.

“A little toasty, but stage one is certainly still intact on the droneship.”

A small fire broke out on the Falcon 9 atop the droneship after landing as seen on the webcast but it was quickly extinguished.

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

KTSAT is South Koreas sole satellite service provider.

Of course North Koreans have no access to any of these services as they are forbidden under the regime of Kim Jong Un with severe penalties for any violators.

The satellite was attached to the booster encapsulated in the nose cone last Friday after engineers successfully completed the routine but required static hot fire test of the first stage engines last Thursday, Oct 26.

Koreasat-5A was built by prime contractor, Thales Alenia Space, responsible for the design, production, testing and ground delivery. It arrived at the Florida launch base on Oct. 5 for integration with the Falcon 9 rocket.

The 3,700 kg (8,160 lb) satellite is equipped with 36 Ku-band transponders and based on Thales Alenia Space’s new-generation Spacebus 4000B2 platform. It will replace Koreasat 5 launched a decade ago in 2006.

The solar panels provide a payload power of approximately 6.5 kW. It will be positioned at 113° East and provide coverage for Indochina, Japan, Korea, the Philippines and the Middle East including Direct to Home (DTH) services.

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

To date SpaceX has now accomplished 19 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

The KoreaSat-5A booster is expected back into Port Canaveral later this week – and the public can watch the sailing action.

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

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

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

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

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

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

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

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

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

The nearly two ton commercial KoreaSat-5A satellite will provide Direct to Home (DTH) broadcasting, maritime, internet and other services to the Asian region centering around South Korea.

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

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

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

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

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

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

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

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

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

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

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

The path to an October launch trifecta from Florida’s Spaceport was cleared following SpaceX’s successful static fire test of the Falcon 9 boosters first stage engines this past Thursday afternoon, Oct. 26.

PLAYALINDA BEACH/KENNEDY SPACE CENTER, FL – The path to an October launch trifecta from Florida’s Spaceport was cleared following SpaceX’s successful static fire test of the Falcon 9 boosters first stage engines this afternoon, Oct. 26, and thereby targeting Monday, Oct. 30 for blastoff of the KoreaSat-5A commercial telecomsat.

KoreaSat-5A is being launched by SpaceX under a commercial contract for South Korean operator KTSAT (a KT Corporation company) using a new first stage and will provide Direct to Home (DTH) broadcasting services.

If all goes well, the end of October KoreaSat-5A liftoff will count as the third rocket launch this month from the sunshine states increasingly busy Spaceport following two earlier launches carried out by both ULA and SpaceX.

Those two mid-month missions involved the commercial SES-11/EchoStar 105 UHDTV satellite on a SpaceX Falcon 9 and the covert NROL-52 spy satellite delivered to orbit on a ULA Atlas V respectively on Oct. 11 and Oct. 15.

The brief engine test of the two stage Falcon 9 took place at 12 noon EDT (1600 GMT) Thursday, Oct. 26, with the sudden eruption of smoke and ash rushing out the north facing flame trench and into the air over historic pad 39A on NASA’s Kennedy Space Center during a very comfortably sunny and windy afternoon – as I witnessed from the crashing waves of Playalinda Beach, FL just a few miles away. See photo and video gallery from myself and space journalist colleague Jeff Seibert.

“Static fire test of Falcon 9 complete,” SpaceX confirmed via tweet soon after the hotfire test was conducted.

“Targeting October 30 launch of Koreasat-5A from Pad 39A in Florida.”

Monday’s mid-afternoon liftoff with the private KoreaSat-5A mission is targeted for a window that opens at 3:34 p.m. EDT (1934 GMT) from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

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

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

SpaceX will also attempt to recover this booster by soft landing on an ocean going platform prepositioned in the Atlantic Ocean – about 8 minutes after blastoff.

Playalinda Beach is a spectacular place to witness the launch from – while surfing the waves too – if you’re in the area.

During today’s hold down static fire test, the rocket’s first and second stages are fueled with 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.

The hold down engine test with the erected Falcon 9 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.

The static fire test lasted approximately three seconds. The test is routinely conducted by SpaceX engineers to confirm the rockets readiness to launch.

The engines exhaust cloud quickly dissipated within about a minute due to the high winds.

Watch this up close static hot fire test video:

The engine test was run without the expensive payload on top to keep it safe in case of a launch pad accident as happened during a fueling test last September with the Israeli AMOS-6 payload.

The rocket will now be rolled back down the pad ramp and into the SpaceX processing hangar at the pad about ¼ mile away for integration with the Koreasat-5A spacecraft encapsulated inside the payload fairing.

In this case the SpaceX Falcon 9 will fly as a brand new rocket rather than a reused booster as happened earlier this month for the SES-11 launch.

The launch will be the 16th this year by a SpaceX Falcon 9 rocket.

Koreasat-5A was built by prime contractor, Thales Alenia Space, responsible for the design, production, testing and ground delivery. It arrived at the Florida launch base on Oct. 5 for integration with the Falcon 9 rocket.

The 3,700 kg satellite is equipped with 36 Ku-band transponders and based on Thales Alenia Space’s new-generation Spacebus 4000B2 platform. It will replace Koreasat 5.

The solar panels provide a payload power of approximately 6.5 kW. It will be positioned at 113° East and provide coverage for Indochina, Japan, Korea, the Philippines and the Middle East including Direct to Home (DTH) services.

What is an Electric Sail? Another Exotic Way to Explore the Solar System

What Is An Electric Sail?
What Is An Electric Sail?

We’re all familiar with the idea of solar sails to explore the Solar System, using the light pressure from the Sun. But there’s another propulsion system that could harness the power of the Sun, electric sails, and it’s a pretty exciting idea.

A few weeks ago, I tackled a question someone had about my favorite exotic propulsion systems, and I rattled off a few ideas that I find exciting: solar sails, nuclear rockets, ion engines, etc. But there’s another propulsion system that keeps coming up, and I totally forgot to mention, but it’s one of the best ideas I’ve heard in awhile: electric sails.

As you probably know, a solar sail works by harnessing the photons of light streaming from the Sun. Although photons are massless, they do have momentum, and can transfer it when they bounce off a reflective surface.

In addition to light, the Sun is also blowing off a steady stream of charged particles – the solar wind. A team of engineers from Finland, led by Dr. Pekka Janhunen, has proposed building an electric sail that will use these particles to carry spacecraft out into the Solar System.

To understand how this works, I’ll need to jam a few concepts into your brain.

First, the Sun. That deadly ball of radiation in the sky. As you probably know, there’s a steady stream of charged particles, mainly electrons and protons, zipping away from the Sun in all directions.

Clouds of southward-pointing plasma are able to peel back layers of the Sun-facing bubble and stack them into layers on the planet's nightside (center, right). The layers can be squeezed tightly enough to reconnect and deliver solar electrons (yellow sparkles) directly into the upper atmosphere to create the aurora. Credit: JPL

Astronomers aren’t entirely sure how, but some mechanism in the Sun’s corona, its upper atmosphere, accelerates these particles on an escape velocity. Their speed varies from 250 to 750 km/s.

The solar wind travels away from the Sun, and out into space. We see its effects on comets, giving them their characteristic tails, and it forms a bubble around the Solar System known as the heliosphere. This is where the solar wind from the Sun meets the collective solar winds from the other stars in the Milky Way.

In fact, NASA’s Voyager spacecraft recently passed through this region, finally making their way to interstellar space.

The solar wind does cause a direct pressure, like an actual wind, but it’s incredibly weak, a fraction of the light pressure a solar sail experiences.

This artist's concept shows the Voyager 1 spacecraft entering the space between stars. Interstellar space is dominated by plasma, ionized gas (illustrated here as brownish haze), that was thrown off by giant stars millions of years ago.Credit: NASA.

But the solar wind contains a stream of positively charged protons and electrons, and this is the key.

An electric sail works by reeling out an incredibly thin wire, just 25 microns thick, but 20 kilometers long. The spacecraft is equipped with solar panels and an electron gun which takes just a few hundred watts to run.

By shooting electrons off into space, the spacecraft maintains a highly positive charged state. Since the protons from the Sun are also positively charged, when they encounter the positively charged tether, they “see” it a huge obstacle 100 meters across, and crash into it.

By imparting their momentum into the tether and spacecraft, the ions accelerate it away from the Sun.

The amount of acceleration is very weak, but it’s constant pressure from the Sun and can add up over a long period of time. For example, if a 1000 kg spacecraft had 100 of these wires extending out in all directions, it could receive an acceleration of 1 mm per second per second.

In the first second it travels 1 mm, and then 2 mm in the next second, etc. Over the course of a year, this spacecraft could be going 30 km/s. Just for comparison, the fastest spacecraft out there, NASA’s Voyager 1, is merely going about 17 km/s. So, much faster, definitely on an escape velocity from the Solar System.

One of the downsides of the method, actually, is that it won’t work within the Earth’s magnetosphere. So an electric sail-powered spacecraft would need to be carried by a traditional rocket away from the Earth before it could unfurl its sail and head out into deep space.

I’m sure you’re wondering if this is a one-way trip to get away from the Sun, but it’s actually not. Just like with solar sails, a electric sail can be pivoted. Depending on which side of the sail the solar wind hits, it either raises or lowers the spacecraft’s orbit from the Sun.

Strike the sail on one side and you raise its orbit to travel to the outer Solar System. But you could also strike the other side and lower its orbit, allowing it to journey down into the inner Solar System. It’s an incredibly versatile propulsion system, and the Sun does all the work.

Although this sounds like science fiction, there are actually some tests in the works. An Estonian prototype satellite was launched back in 2013, but its motor failed to reel out the tether. The Finnish Aalto-1 satellite was launched in June 2017, and one of its experiments is to test out an electric sail.

We should find out if the technique is viable later this year.

It’s not just the Finns who are considering this propulsion system. In 2015, NASA announced that they had awarded a Phase II Innovative Advanced Concepts grant to Dr. Pekka Janhunen and his team to explore how this technology could be used to reach the outer Solar System in less time than other methods.

The Heliopause Electrostatic Rapid Transit System, or HERTS spacecraft would extend 20 of these electric tethers outward from the center, forming a huge circular electric sail to catch the solar wind. By slowly rotating the spacecraft, the centrifugal forces will stretch the tethers out into this circular shape.

With its positive charge, each tether acts like a huge barrier to the solar wind, giving the spacecraft an effective surface area of 600 square kilometers once it launches from the Earth. As it gets farther, from Earth, though, its effective area increases to the equivalent of 1,200 square km by the time it reaches Jupiter.

When a solar sail starts to lose power, an electric sail just keeps accelerating. In fact, it would keep accelerating out past the orbit of Uranus.

If the technology works out, the HERTS mission could reach the heliopause in just 10 years. It took Voyager 1 35 years to reach this distance, 121 astronomical units from the Sun.

But what about steering? By changing the voltage on each wire as the spacecraft rotates, you could have the whole sail interact differently on one side or the other to the solar wind. You could steer the whole spacecraft like the sails on a boat.

In September 2017, a team of researchers with the Finnish Meteorological Institute announced a pretty radical idea for how they might be able to use electric sails to comprehensively explore the asteroid belt.

Instead of a single spacecraft, they proposed building a fleet of 50 separate 5-kg satellites. Each one would reel out its own 20 km-long tether and catch the Sun’s solar wind. Over the course of a 3-year mission, the spacecraft would travel out to the asteroid belt, and visit several different space rocks. The full fleet would probably be able to explore 300 separate objects.

This image depicts the two areas where most of the asteroids in the Solar System are found: the asteroid belt between Mars and Jupiter, and the trojans, two groups of asteroids moving ahead of and following Jupiter in its orbit around the Sun.

Each spacecraft would be equipped with a small telescope with only a 40 mm aperture. That’s about the size of a spotting scope, or half a pair of binoculars, but it would be enough to resolve features on the surface of an asteroid as small as 100 meters across. They’d also have an infrared spectrometer to be able to determine what minerals each asteroid is made of.

That’s a great way to find that $10 trillion asteroid made of solid platinum.

Because the spacecraft would be too small to communicate all the way back to Earth, they’d need to store the data on board, and then transmit everything once they came past our planet 3 years later.

The planetary scientists I’ve talked to love the idea of being able to survey this many different objects at the same time, and the electric sail idea is one of the most efficient methods to do it.

According to the researchers, they could do the mission for about $70 million, bringing the cost to analyze each asteroid down to about $240,000. That would be cheap compared to any other method proposed of studying asteroids.

Space exploration uses traditional chemical rockets because they’re known and reliable. Sure they have their shortcomings, but they’ve taken us across the Solar System, to billions of kilometers away from Earth.

But there are other forms of propulsion in the works, like the electric sail. And over the coming decades, we’re going to see more and more of these ideas put to the test. A fuel free propulsion system that can carry a spacecraft into the outer reaches of the Solar System? Yes please.

I’ll keep you posted when more electric sails are tested.

Twice Flown SpaceX Booster Sails Proudly into Port Canaveral at Sunrise 3 Days After Sunset Launch and Droneship Landing: Photos

PORT CANAVERAL/KENNEDY SPACE CENTER, FL – The now twice flown SpaceX first stage booster that successfully delivered the SES-11 UHDTV satellite to orbit at sunset Wednesday, Oct 11, sailed proudly back home into Port Canaveral during a beautiful Sunday sunrise, Oct. 15 only three days after it safely landed on a tiny droneship at sea.

The booster arrival also took place just hours after a ULA Atlas launched the covert NROL-52 surveillance satellite for the US National Reconnaissance Office (NRO) – making for a nonstop day of space action on the Florida Space Coast.

The 156-foot-tall Falcon 9 booster accomplished a precision guided rocket assisted touchdown on the football field sized OCISLY droneship platform about 8 minutes after the dinnertime liftoff with the private SES-11/EchoStar 105 communications satellite on Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida.

The 15 story tall first stage came to rest slightly tilted a few degrees, similar to at least two prior boosters that soft landed upright on OCISLY while prepositioned several hundred miles off shore of the Florida peninsula in the Atlantic Ocean.

The recycled booster was towed into Port Canaveral by a SpaceX contracted tugboat accompanied by a small fleet of pilot ships and support vessels.

The doubly used and doubly successful booster entered the mouth of Port Canaveral around 7:15 a.m. EDT Sunday under dawns delightful twilight I witnessed from Jetty Park and beach together with a few space media colleagues and a small crowd of onlookers with little fanfare.

Over the next hour it was hauled through the narrow channel as numerous vessels large and small and pleasure craft sailed by, likely wondering what they were looking it.

Finally the droneship platform was docked at SpaceX’s spot leased near the two huge shipping cranes dominating the scene across from popular portside restaurants – and also not far from humongous cruise ships dwarfing the booster in size.

The next step was for dock workers to hoist a cap and attach it to the top of the booster. This enabled it to eventually be carefully raised off the barge with a crane by about 1 p.m. and then slowly moved and swung over and affixed onto a restraining pedestal stand on land.

By the next evening Monday night, all 4 landing legs were still intact. After they are all detached the booster will be lowered horizontally aided by the cabling attached by the workers and placed on a flab bed transporter and trucked back to the Cape.

However the impact of developing and reusing ‘used’ rockets is leading to an era when re-flown rockets are offered as a ‘routine service’ rather than the exception.

Rocket reusability is at the heart of the extraordinary vision of billionaire entrepreneur and SpaceX CEO Elon Musk to drastically cut space launch costs and one day build a ‘City on Mars’.

And it represents a ‘major sea change getting closer’ to fruition with each passing day thanks to SpaceX, said SES CTO Martin Halliwell in an exclusive interview with Universe Today, following the stunning sunset blastoff of the SES-11 UHDTV commercial satellite on another ‘flight-proven’ Falcon 9 booster that also re-landed – thus completing another remarkable round of rocket recovery and recycling or ‘launch, land and relaunch!’

“As I’ve said before, I think in a couple years time you won’t even consider whether it’s a preflown rocket or a new rocket or a second time rocket,” SES Chief Technology Officer Martin Halliwell told Universe Today in a one-on-one post launch interview.

“It will just be a flight and you will buy a service to get to orbit – and that will be that!”

“It’s a major sea change,” Halliwell explained. “That’s absolutely true.”

“We’re getting closer to that every day. It’s exactly where we are going. There is no doubt about it.”

The launch of EchoStar 105/SES-11 counts as only the third recycled SpaceX Falcon 9 ever to be launched and is the third successful mission with a flight-proven orbital class rocket.

All three ‘flight-proven’ missions have lifted off from Pad 39A this year and all three have relanded.

The Falcon 9 first stage appeared to be in good shape upon its return to Port. I did not observe noticeable significant damage to the outside of the booster skin, grid fins or landing legs. Scorching seemed comparable to the first two reflown boosters.

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

On arrival it was clearly anchored to the OCISLY droneship deck with multiple chains as previously done for droneship landings as well as with what appears to be several gripper arms.

OCISLY, which stands for “Of Course I Still Love You,” had departed Port Canaveral several days ahead of the Oct. 11 launch and was prepositioned in the Atlantic Ocean 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.

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.

NASA is also assessing whether to utilize a reflown booster on upcoming ISS resupply missions – starting with the next flight of the Dragon CRS-13 cargo ship which may liftoff as soon as early December.

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

To date SpaceX has accomplished 18 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

KENNEDY SPACE CENTER, FL – Elon Musk’s extraordinary vision of an era when re-flown rockets are offered as a ‘routine service’ rather than the exception is a ‘major sea change getting closer’ to fruition with each passing day thanks to SpaceX, said SES CTO Martin Halliwell in an exclusive interview with Universe Today, following the stunning sunset blastoff of the SES-11 UHDTV commercial satellite on another ‘flight-proven’ Falcon 9 booster that also re-landed – thus completing another remarkable round of rocket recovery and recycling or ‘launch, land and relaunch!’

“The launch was fantastic,” Halliwell gushed. “Everything went perfectly. The countdown went perfectly, no hiccups, no drama, nothing whatsoever. So we were good to go!”

Plus its saving SES “months of time” and thereby “tens of millions of dollars of real money” to fly with a used booster rather than having their expensive satellite sit and languish uselessly on the ground.

SES-11 is primarily intended to significantly upgrade SES capabilities to transmit Ultra High Definition (UHD) TV signals or 4 K vs. standard HDTV – thereby pulling in more revenue streams.

SES made rocket history jointly with SpaceX earlier this year when they became the first company ever to agree to fly a payload on a recycled liquid fueled rocket that SpaceX’s billionaire CEO Elon Musk dubs ‘flight-proven’.

And Halliwell, as SES Chief Technology Officer, was instrumental in partnering with SpaceX CEO Musk to take a big leap make that happen.

The maiden ‘used’ Falcon 9 lifted off successfully with the SES-10 satellite and delivered the comsat to geostationary orbit on March 30, 2017 – in a monumental space achievement.

“This was our second reflown mission with SpaceX for SES-11. And we had a lot of discussion about it.”

“The more that we looked at it and the transparency we’ve gotten from SpaceX, working together with them we were convinced of the ‘flight worthiness’ of the Falcon 9 vehicle,” Halliwell told me.

SpaceX successfully delivered the 5.7 ton EchoStar 105/SES-11 joint mission satellite for SES and EchoStar to geostationary transfer orbit some 22,000 miles (36,000 kilometers) above the equator.

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.

How exactly does Halliwell and SES assess whether its worth taking a gamble on a ‘flight-proven’ booster to ensure it meets the high standards expected and really is robust and reliable and not end in disaster? How did the booster fare after the first reflown mission for SES-10?

Halliwell explained that SES employs a team of engineers embedded with SpaceX.

“We have US citizens who work embedded with SpaceX,” Halliwell replied. “They can understand and filter and react to that data they are exposed to and see what’s going on. And then determine if we are good to go or not.”

Why did SES decide on using a pre-flown booster?

“We sat down with SpaceX to see how the launch manifest and scheduling looks and asked whats the best way we can get SES-11 to orbit? Do we wait for new equipment or does SpaceX have preflown equipment that you can make available to us after refurbishment?”

“It came out that the fastest way we can get to orbit is by using a refurbished preflown vehicle. So we said OK we will go down that path. And that’s why we are here today.”

Did it save time or money for SES to go with a used booster?

“It saved us a few months. So we concentrated on the preflown booster after making that decision. For sure if we had chosen to use a new booster our SES-11 launch would have been somewhat later compared to launching today.”

So it turns out that SES got a faster trip to orbit for SES-11 and that in turn quickly translates into real money generated instead of more money wasted with a satellite parked somewhere in a storage shed for half a year of more. The actual savings on a launch was not that big.

“The average launch delay we have right now is about 7 months,” Halliwell explained.

“So we have the spacecraft already built and its ready, and ready to ship [to the launch site]. And then – we just wait! Until we have launch vehicle availability.”

“So think about it. I spent all my money on my spacecraft and most of my money on my launch vehicle. Plus a whole chunk of insurance money is already gone.”

“So I’m sitting there for 7 months. It’s just cash out and a very expensive wait!”

How much money does waiting around on the ground with a fully ready to launch spacecraft cost?

“That works out to tens of millions of dollars lost due to delays,” he replied. “Its real money. A ton of money!”

“Revenue we are not making. And paying for the money you spent. It’s gone !”

So with SES-11 now safely in orbit it will soon be generating revenue to recoup all the investments thus far accrued.

Is the era of reliable rocket reusability coming even sooner than some had expected?

“I think so certainly for SpaceX,” Halliwell responded.

“The other companies are all now running behind. You look towards Ariane with the reusable Prometheus and being cheaper – but there is a ways to go there. You look at Blue Origin and they are making progress. But they are not there yet.”

“Will Vulcan do this? I think everybody will consider this, and try to figure out the pros and cons of this and try to figure out an industrial model and a financial model, etc, etc.”

“Whether they go down that reusability path or not depends on whether it suits their business plan.”

“SpaceX has certainly taken a very, very difficult road. But they have come through it very well.”

Is SpaceX actually saving money? The company sunk huge sums of its own money amounting into the hundreds of millions of dollars to develop the reusability technology.

The advertised cost of a SpaceX launch is about $61 million.

Elon Musk routinely promotes the reusability technology as a means to drastically reduce space launch costs.

Thus SES CEO Karim Michel Sabbagh is looking for a reduction to about half that advertised price, in the neighborhood of $30 million.

To date Musk has only offered a marginal reduction to the contact price, citing the high development costs.

Musk has even joked that he should charge more for a reliable ‘flight-proven’ booster.

Halliwell says the real benefit thus far is the earlier launch date. SpaceX has a huge backlog of over 50 contracted launches that only grew longer following a pair of rocket explosions that forced launch delays while the firm investigated root causes.

What does Halliwell think is realistic regarding pricing and achieving the $30 million target?

“I’d love to see that,” Halliwell told me. “But I don’t think we’ll see that $30 million any time soon. Maybe it will stabilize in the mid $50 millions or $60 millions somewhere. I think that’s realistic.”

“I think we have to see how people like SpaceX work on their industrial/financial model.”

“To be honest, I think SpaceX themselves is trying to figure out where the pricing should be. How much is it really costing them? How much is the refurb costing them? How much are their ops costing?”

To date SpaceX has accomplished 18 successful landings of a recovered Falcon 9 first stage booster by land and by sea.

The first stage stands 156 feet tall.

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 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.

KENNEDY SPACE CENTER, FL – SpaceX is all set for a sunset blastoff Wednesday, Oct. 11 of the commercial SES-11/EchoStar 105 Ultra High Definition (UHD) TV satellite serving North America on a ‘used’ Falcon 9 booster from the Florida Space Coast – that is also targeted to re-land a second time on an sea going platform off shore in the Atlantic.

Spectators should enjoy a spectacular view of the SpaceX Falcon 9 dinnertime launch with a forecast of extremely favorable weather conditions. This comes on the heels of multiple deluges of torrential rain that twice scrubbed last week’s launch of a United Launch Alliance V carrying a USAF spy satellite.

The private SES-11/EchoStar 105 communications satellite mission will launch on a ‘flight-proven’ booster and is slated for a dinnertime liftoff on Oct. 11 at 6:53 p.m. EDT from seaside Launch Complex 39A at NASA’s Kennedy Space Center in Florida, carrying the SES-11.

All systems are GO at L Minus 1 Day!

“#EchoStar105 is targeted for launch Oct. 11 from launch Complex 39A at NASA’s Kennedy Space Center in Florida-launch window 6:53-8:53 PM EDT,” EchoStar tweeted today.

“Getting Echostar-105/#SES11 ready for launch!” SES tweeted further.

If all goes well this will be 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!

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 today, erected to vertical launch position and is now poised for liftoff Wednesday.

It will launch the two and a half ton EchoStar 105/SES-11 to geostationary orbit some 22,000 miles (36,000 kilometers) above the equator.

SpaceX will also attempt to recover this recycled Falcon 9 first stage booster again by soft landing on a droneship platform prepositioned hundreds of miles off shore in the Atlantic Ocean – some 8 minutes after blastoff.

Spectacular weather is expected Wednesday for space enthusiasts gathering in local regional hotels after traveling here from across the globe.

Playalinda Beach is among the best places to witness the launch from – while surfing the waves too – if you’re in the area.

You can watch the launch live on a SpaceX dedicated webcast starting about 10 minutes prior to the 6:53 pm EDT or 10:53 pm UTC liftoff time.

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

The two hour long launch window closes at 8:53 p.m. EDT.

The weather outlook is currently exceptional along the Florida Space Coast with a 90% chance of favorable conditions at launch time according to U.S. Air Force meteorologists with the 45th Space Wing Weather Squadron at Patrick Air Force Base. The primary concerns on Oct. 11 are only for Cumulus Clouds.

The odds remain high at 90% favorable for the 24 hour scrub turnaround day on Oct. 12.

The 45th Space Wing forecast is also favorable for the landing recovery area through Thursday “when a low pressure system may move into the area, increasing winds and seas. This low will migrate west and possibly impact Florida by the weekend.”

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

The path to launch was cleared following last weeks successful static fire test of the first stage engines Falcon 9.

During the Oct. 2 static fire test, the rocket’s first and second stages were fueled with liquid oxygen and RP-1 propellants like an actual launch, and a simulated countdown was carried out to the point of a brief engine ignition.

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 – minus the expensive payload.

Following the hot fire test, the rocket was rolled back to the processing hangar located just outside the pad perimeter fence.

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