The 30 day flight of the SpaceX-3 Dragon commercial cargo freighter loaded with a huge cache of precious NASA science experiments including a freezer packed with research samples ended today with a spectacular departure from the orbiting lab complex soaring some 266 miles (428 km) above Earth.

Update 3:05 PM EDT May 18: SpaceX confirms successful splashdown at 3:05 p.m. EDT today.

“Splashdown is confirmed!! Welcome home, Dragon!”

Robotics officers at Mission Control at NASA’s Johnson Space Center detached Dragon from the Earth-facing port of the Harmony module at 8 a.m. EDT (1300 GMT) this morning, Sunday, May 18, 2014 using the stations Canadian-built robotic arm.

Engineers had earlier unbolted all 16 hooks and latches firmly connecting the vehicle to the station in preparation.

NASA astronaut Steve Swanson then commanded the gum dropped shaped Dragon capsule’s release from Canadarm2 as planned at 9:26 a.m. EDT (1326 GMT) while the pair were flying majestically over southern Australia.

The undocking operation was shown live on NASA TV.

Swanson was assisted by Russian cosmonaut Alexander Skvortsov as the US- Russian team were working together inside the domed Cupola module.

Following the cargo ships release by the 57 foot long arms grappling snares, Swanson carefully maneuvered the arm back and away from Dragon as it moved ever so slowly in free drift mode.

It was already four feet distant within three minutes of release.

Three departure burns by the Dragon’s Draco maneuvering thrusters followed quickly in succession and occurred precisely on time at 9:29, 9:30 and 9:38 a.m. EST.

Dragon exited the 200 meter wide keep out zone – an imaginary bubble around the station with highly restricted access – at the conclusion of the 3rd departure burn.

“The Dragon mission went very well. It was very nice to have a vehicle take science equipment to the station, and maybe some day even humans,” Swanson radioed after the safe and successful departure was completed.

“Thanks to everyone who worked on the Dragon mission.”

The private SpaceX Dragon spent a total of 28 days attached to the ISS.

The six person international crew from Russia, the US and Japan on Expeditions 39 and 40 unloaded some 2.5 tons of supplies aboard and then repacked it for the voyage home.

The SpaceX resupply capsule is carrying back about 3500 pounds of spacewalk equipment, vehicle hardware, science samples from human research, biology and biotechnology studies, physical science investigations and education activities, as well as no longer needed trash.

“The space station is our springboard to deep space and the science samples returned to Earth are critical to improving our knowledge of how space affects humans who live and work there for long durations,” said William Gerstenmaier, associate administrator for human exploration and operations.

“Now that Dragon has returned, scientists can complete their analyses, so we can see how results may impact future human space exploration or provide direct benefits to people on Earth.”

Among the research investigations conducted that returned samples in the cargo hold were an examination of the decreased effectives of antibiotics in space, better growth of plants in space, T-Cell activation in aging and causes of human immune system depression in the microgravity environment.

The 10 minute long deorbit burn took place as scheduled at 2:10 p.m. EDT (1810 GMT) today.

Dragon returned to Earth for a triple parachute assisted splash down today at around 3:02 p.m. EDT (19:02 GMT) in the Pacific Ocean – some 300 miles west of Baja California.

It will be retrieved by recovery boats commissioned by SpaceX. The science cargo will be extracted and then delivered to NASA’s Johnson Space Center within 48 hours.

Dragon thundered to orbit atop SpaceX’s powerful new Falcon 9 v1.1 rocket on April 18, from Cape Canaveral, Fla.

This unmanned Dragon delivered about 4600 pounds of cargo to the ISS including over 150 science experiments, a pair of hi tech legs for Robonaut 2, a high definition Earth observing imaging camera suite (HDEV), the laser optical communications experiment (OPALS), the VEGGIE lettuce growing experiment as well as essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard in low Earth orbit.

It reached the ISS on April 20 for berthing.

Dragon is the only unmanned resupply vessel supply that also returns cargo back to Earth.

The SpaceX-3 mission marks the company’s third resupply mission to the ISS under the $1.6 Billion Commercial Resupply Services (CRS) contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.

The SpaceX Dragon is among a trio of American vehicles, including the Boeing CST-100 and Sierra Nevada Dream Chaser vying to restore America’s capability to fly humans to Earth orbit and the space station by late 2017, using seed money from NASA’s Commercial Crew Program (CCP) in a public/private partnership. The next round of contracts will be awarded by NASA about late summer 2014.

Another significant milestone was the apparently successful attempt by SpaceX to accomplish a controlled soft landing of the Falcon 9 boosters first stage in the Atlantic Ocean for eventual recovery and reuse. It was a first step in a guided 1st stage soft landing back at the Cape.

The next unmanned US cargo mission to the ISS is set for early morning on June 10 with the launch of the Orbital Sciences Cygnus freighter atop an Antares booster from a launch pad at NASA’s Wallops Flight Facility on the eastern shore of Virginia.

To close out their final week aboard the International Space Station, three of the six Expedition 39 crew members are completing their unloading tasks inside the docked commercial SpaceX Dragon cargo freighter and other duties while teams at Mission Control in Houston conduct delicate robotics work outside with dazzling maneuvers of the Dextre robot to remove the last external experiment from the vessels storage truck.

See a dazzling gallery of photos of Dextre dangling outside the docked Dragon depot – above and below.

On Monday, May 5, the robotics team at NASA Mission Control Center at the Johnson Space Center in Houston carefully guided Canada’s Dextre robotic “handyman” attached to the end of the 57-foot long Canadarm2 to basically dig out the final payload item housed in the unpressurized trunk section at the rear of the SpaceX Dragon cargo vessel docked to the ISS.

Dextre stands for “Special Purpose Dexterous Manipulator” and was contributed to the station by the Canadian Space Agency. It measures 12 feet tall and is outfitted with a pair of arms and an array of finely detailed tools to carry out intricate and complex tasks that would otherwise require spacewalking astronauts.

The massive orbiting outpost was soaring some 225 miles above the home planet as Dextre’s work was in progress to remove the Optical PAyload for Lasercomm Science, or OPALS, from the Dragon’s truck.

The next step is to install OPALS on the Express Logistics Carrier-1 (ELC-1) depot at the end of the station’s port truss on Wednesday.

Monday’s attempt was the second try at grappling OPALS. The initial attempt last Thursday “was unsuccessful due to a problem gripping the payload’s grapple fixture with the Special Purpose Dextrous Manipulator, or Dextre,” NASA reported.

A software patch solved the problem.

OPALS uses laser light instead of radio waves to beam back precisely guided data packages to ground stations. The use of lasers should greatly increase the amount of information transmitted over the same period of time, says NASA.

The science experiments carried aboard Dragon are intended for research to be conducted by the crews of ISS Expeditions 39 and 40.

Robotics teams had already pulled out the other payload item from the truck, namely the HDEV imaging suite. It is already transmitting back breathtaking real time video views of Earth from a quartet of video cameras pointing in different directions mounted on the stations exterior.

The SpaceX CRS-3 mission marks the company’s third resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016.

After spending six months in space, Station Commander Koichi Wakata from Japan as well as NASA astronaut Rick Mastracchio and Russian cosmonaut Mikhail Tyurin will be departing the station in a week aboard their Soyuz TMA-11M spacecraft on May 13 at 6:33 p.m. EDT.

They are scheduled to land some 3.5 hours later in the steppes of Kazakhstan at 9:57 p.m. (7:57 a.m. Kazakh time on May 14). The events will be carried live on NASA TV.

To prepare for the journey home, the trio also completed fit checks on their Russian Sokol launch and entry suits on Monday.

Meanwhile Dragon is also set to depart the station soon on May 18 for a parachute assisted splashdown and recovery by boats in the Pacific Ocean west of Baja California.

Dragon has been docked to the station since arriving on Easter Sunday morning, April 20.

It was grappled using Canadarm 2 and berthed at the Earth facing port of the Harmony module by Commander Wakata and flight engineer Mastracchio while working at the robotics work station inside the seven windowed domed Cupola module.

For the return trip, the Expedition 39 crew is also loading Dragon with precious science samples collected over many months from the crews research activities as well as trash and no longer needed items.

SpaceX Releases Raw Video of First Stage Landing Attempt

Video released today by SpaceX confirms the landing legs deployed successfully on the Falcon 9’s first stage booster, paving the way for future vertical soft touchdowns on land. SpaceX’s next-generation Falcon 9 rocket was tested following the launch of the CRS-3 mission for the Dragon spacecraft, which launched from Cape Canaveral Air Force Station on April 18. This was the first test of the landing legs deployment with a re-entry burn and soft landing in the Atlantic Ocean.

The SpaceX CEO had mentioned the success during a post launch briefing and later tweeted further updates that the Falcon 9 first stage actually made a good water landing despite rough seas, with waves swelling at least six feet. He also spoke briefly of the success during a news conference at the National Press Club on April 25, saying video would be released soon.

The video above is actually a cleaned-up (repaired) version of the original. There are a short few frames which show the landing legs deployed just before splashdown, which Musk highlighted in a recent Tweet. Obviously this is not the greatest-quality video ever released, but exciting still the same. SpaceX is actually looking for help in cleaning up the video even further.

SpaceX CEO Elon Musk Sues Government to Break US Air Force’s National Security Launch Monopoly

SpaceX CEO Elon Musk announces lawsuit protesting Air Force launch contracts while speaking at the National Press Club in Washington, DC on April 25, 2014

SpaceX CEO Elon Musk announces lawsuit protesting Air Force launch contracts while speaking at the National Press Club in Washington, DC on April 25, 2014
Story updated[/caption]

Elon Musk, CEO and founder of the upstart commercial launch venture SpaceX, announced at a press conference today, Friday, April 25, that SpaceX is filing suit against the Federal Government to protest and break the US Air Force’s awarding of lucrative launch contracts for high priority national security satellites to a sole rocket provider – United Launch Alliance (ULA) – on a non competitive basis.

The gloves are officially off in the intensely mounting duel over multibillion dollar Air Force military launch contracts between SpaceX and ULA.

“The official protest document will be available Monday, April 28th at www.freedomtolaunch.com and will be filed with the United States Court of Federal Claims in Washington, D.C.,” said SpaceX in an official statement.

Musk said the Air Force launch contract with ULA amounted to a continuing monopoly, was unfair by blocking SpaceX from competing for launches of surveillance satellites and would cost taxpayers billions of extra dollars in coming years.

“What we feel is that this is not right – that the national security launches should be put up for competition and they should not be awarded on a sole source, uncompeted basis,” said Musk at the briefing called on short notice and held at the National Press Club in Washington, DC.

The latest Air Force launch contract dated to December 2013 guarantees the “block buy” purchase of 36 rocket cores from ULA for national security launches for the DOD, NRO and other government agencies, at a significantly reduced cost compared to earlier contracts.

A further 14 cores were to be awarded on a competitive basis, including bids from SpaceX and others who seek to gain Air Force certification. Several of those launch awards have now been deferred indefinitely.

ULA is a joint venture between aerospace giants Boeing and Lockheed Martin, formed in 2006, that has launched over 80 satellites to orbit and beyond including many NASA science and mission probes like Orion EFT-1, Curiosity, MAVEN, TDRS and more.

It manufactures the Delta IV and Atlas V unmanned, expendable rocket families that are currently the only boosters certified to launch the high value military payloads at issue in the lawsuit announced on Friday by Musk.

The newest versions of the Delta and Atlas rockets – known as EELV’s (Evolved Expendable Launch Vehicles) have had nearly flawless records of success since being introduced some dozen years ago by the companies individually, before the ULA merger.

Musk wants his company’s newer and he says much cheaper Falcon 9 and Falcon Heavy rockets to be certified by the Air Force and included in the competition for launch contracts.

To date the Falcon 9 has launched only 9 times. Only four of those were in the new and more powerful configuration needed by the Air Force.

Musk is not asking that the launches be awarded outright to SpaceX. But he does want the Air Force contract cancelled and re-competed.

“We’re just protesting and saying that the launches should be competed,” Musk said.

“If we compete and lose that’s fine. But why were they not even competed? That just doesn’t make sense.”

“So far we are most of the way through the certification process. And so far there have been zero changes to the rocket. Mostly it’s just been a paperwork exercise.”

“Since this is a large multiyear contract, why not wait a few months for the certification process to complete. And then do the competition. That seems very reasonable to me.”

Musk said it costs four times more to launch ULA’s Delta or Atlas rocket vs. a SpaceX Falcon rocket.

“The ULA rockets are basically four times more expensive than ours. So this contract is costing US taxpayers billions of dollars for no reason.”

“Each launch by ULA costs American taxpayers roughly $400 million per launch. They are insanely expensive. I don’t know why they are so expensive.”

The Falcon 9 lists for about $60 Million per launch, but rises to about $100 million after the certification costs are included, Musk explained.

“So yes the certification does make our Falcon 9 rocket more expensive. But not 400% more expensive.”

“Our rockets are 21st century design,” said Musk to obtain the most efficiency. He said ULA’s designs date back to the 90s and earlier with heritage hardware.

To date the Falcon 9 has already been used three times under a $1.6 Billion contract with NASA to launch the private SpaceX Dragon resupply vessel to the International Space Station (ISS) – most recently a week ago during the April 18 blastoff of the SpaceX CRS-3 mission from Cape Canaveral.

It is also being used to launch highly expensive communications satellites like SES-8 and Thaicom-6 for private companies to geostationary orbits.

“It just seems odd that if our vehicle is good enough for NASA and supporting a $100 billion space station, and it’s good enough for launching NASA science satellites, for launching complex commercial geostationary satellites, then there’s no reasonable basis for it not being capable of launching something quite simple like a GPS satellite,” said Musk.

“Our only option is to file a protest.”

Furthermore as I wrote here in a prior article, US National Security launches are now potentially at risk due to the ongoing crisis between Russian, Ukraine and Crimea because the RD-180 first stage engines powering the Atlas V are designed and manufactured in Russia by NPO Energomash, majority owned by the Russian Federation.

“The head of the Russian space sector, Dmitry Rogozin, was sanctioned by the White House in March 2014 in the wake of Russia’s aggression in Ukraine,” says SpaceX.

The RD-180 engine supply could be cut off in a worst case scenario if economic sanctions against Russia are increased by the Western allies.

ULA has a two year contingency supply of the RD-180’s and blueprints to begin production, if needed.

However in the event of a cutoff, it would take at least three to five years to start and certify RD-180 engine production somewhere in the US, a ULA spokesperson told me recently at Cape Canaveral.

This possibly leaves a 1 to 3 year gap with no Atlas V 1st stage engine supply.

The Delta IV rockets and engines by contrast are manufactured in the US.

“In light of international events, this seems like the wrong time to send hundreds of millions of dollars to the Kremlin,” said Musk.

“Yet, this is what the Air Force’s arrangement with ULA does, despite the fact that there are domestic alternatives available that do not rely on components from countries that pose a national security risk.”

Stunning Original Drawing of the Latest SpaceX Launch

An original pencil illustration of the SpaceX CRS-3 Falcon 9 Dragon launch on April 18, 2014. Credit and copyright: Wendy Clark.

Here’s something you don’t see much anymore: an original pencil drawing of a launch. This drawing by Wendy Clark from the UK is reminiscent of the pre-spaceflight days, before we had actual images of launches, and just our dreams of spaceflight. This isn’t the first time Clark has drawn a launch (here’s an article we posted of her drawings of the MAVEN launch and the final space shuttle launch) but this one is almost a contrast in themes: the latest technology in launches from the upstart SpaceX team vs. an old-school, old fashioned, by-hand product.

For this drawing, she reiterated what she told us previously: “Don’t let anyone tell you drawing a rocket is easy!” Clark said on Flickr. “The Strongback was a complete dog of an object to draw, such a maze of engineering.”

She also captured the ‘dirty’ side of launches: “Dust and gravel being thrown up everywhere, and the lovely Falcon 9 rocket was a little grubby on lift-off and I’ve tried to reflect that in the drawing,” she said.

Thanks to Wendy Clark for sharing her work on Universe Today’s Flickr site. See more of her drawings and photography on her own Flickr page.

SpaceX Makes Strides Towards 1st Stage Falcon Rocket Recovery during Space Station Launch

The powerful SpaceX Falcon 9 rocket that launched successfully on a cargo delivery run for NASA bound for the Space Station on Friday, April 18, from Cape Canaveral, Fla, also had a key secondary objective for the company aimed at experimenting with eventually recovering the rockets first stage via the use of landing legs and leading to the boosters refurbishment and reuse further down the road.

Marking a first of its kind test, this 20 story tall commercial Falcon 9 rocket was equipped with a quartet of landing legs to test controlled soft landing techniques first in the ocean and then back on solid ground at some later date this year or next – by reigniting the 1st stage engines for a guided touchdown.

The 12 foot diameter Falcon 9 rocket would sprout the legs just prior to water impact for the controlled soft landing in the Atlantic Ocean, guided by SpaceX engineers.

Prior to the launch SpaceX managers were careful not to raise expectations.

“The entire recovery of the first stage is completely experimental,” said Hans Koenigsmann, SpaceX vice president of mission assurance. “It has nothing to do with the primary mission.”

He estimated the odds of successfully retrieving an intact booster at merely 30 or 40 percent.

Following Friday’s blastoff, SpaceX reported they made significant strides towards that goal of a 1st stage recovery.

SpaceX engineers had preprogrammed the spent first stage to relight several Merlin 1 D engines after completing the boost phase and stage seperation to stabilize it, reduce its roll rate and then gradually lower its altitude back down to the Atlantic Ocean’s surface for a soft landing attempt and later possible recovery by retrieval ships.

All these critical steps seemed to go fairly well in initial reports that are subject to change.

SpaceX CEO and founder Elon Musk reported at a post launch briefing and later tweeted further updates that the Falcon 9 first stage actually made a good water landing despite rough seas, with waves swelling at least six feet.

“Roll rate close to zero (v important!).”

“Data upload from tracking plane shows landing in Atlantic was good! Several boats enroute through heavy seas,” Musk tweeted.

Furthermore he reported that the 1st stage survived the ocean touchdown.

“Flight computers continued transmitting for 8 seconds after reaching the water. Stopped when booster went horizontal.”

Because of the high waves, the recovery boats had difficulty reaching the booster in the recovery area located some two hundred miles off shore from Cape Canaveral.

Several previous attempts by SpaceX to recover the first stage via parachutes and thrusters were not successful. So SpaceX adopted this new approach with the landing legs and 1st stage Merlin 1 D engines.

Further details will be proved when they become available.

The attachment of the 25 foot long 1st stage landing legs to SpaceX’s next-generation Falcon 9 rocket for ocean recovery counts as a major step towards the firm’s future goal of building a fully reusable rocket and dramatically lowering launch costs compared to expendable boosters.

The eventual goal is to accomplish a successful first stage touchdown by the landing legs on solid ground back somewhere near on Cape Canaveral, Florida.

Musk said that SpaceX is still working out the details on finding a suitable landing location with NASA and the US Air Force.

Extensive work and testing remains to develop and refine the technology before a land landing will be attempted by the company, says Musk.

It will be left to future missions to accomplish a successful first stage touchdown by the landing legs back on solid ground back through a series of ramped up rocket tests at Cape Canaveral, Florida.

“Even though we probably won’t get the stage back, I think we’re really starting to connect the dots of what’s needed,” Musk said at the briefing.

“There are only a few more dots that need to be there to have it all work. I think we’ve got a decent chance of bringing a stage back this year, which would be wonderful.”

Overall Musk was very pleased with the performance of the rocket and the landing leg test.

“I would consider it a success in the sense that we were able to control the boost stage to a zero roll rate, which is previously what has destroyed the stage, an uncontrolled roll, where the on-board nitrogen thrusters weren’t able to control the aerodynamic torque and spun up.”

“This time, with more powerful thrusters and more nitrogen propellant, we were able to null the roll rates.”

“I’m feeling pretty excited,” Musk stated. “This is a happy day. Most important of all is that we did a good job for NASA.”

This extra powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level rises to 1.5 million pounds as the rocket climbs to orbit.

Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.

Indeed Dragon is loaded with nearly 5000 pounds of cargo, about double the weight carried previously.

If all goes well, Dragon will reach the ISS early on Easter Sunday morning after a two day orbital chase.

Station crew members Rick Mastracchio and Steven Swanson will grapple the Dragon cargo freighter with the 57 foot long Canadarm2 on Easter Sunday at about 7:14 a.m. and then berth it at the Earth-facing port of the Harmony module.

NASA TV coverage of the Easter Sunday grappling process will begin at 5:45 a.m. with berthing coverage beginning at 9:30 a.m. : http://www.nasa.gov/ntv

SpaceX Dragon launch to ISS Marches Towards April 18 Liftoff after Helium Leak Forces Scrub – Watch Live

NASA and SpaceX are marching forward towards a Friday, April 18 liftoff attempt for the Falcon 9 rocket sending a commercial Dragon cargo craft on the company’s third resupply mission to the International Space Station following the scrubbed launch attempt on Monday, April 14 – forced by the discovery of a Helium gas leak inside the rocket during the latter stages of the countdown.

An on time blastoff of the upgraded Falcon 9 sets the stage for an Easter Sunday rendezvous and berthing of the Dragon resupply spacecraft at the massive orbiting outpost packed with almost 5000 pounds of science experiments and supplies for the six person crew.

However the weather prognosis is rather iffy for Friday afternoons launch attempt at 3:25:21 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

Forecasters predict only a 40 percent “GO” of acceptable weather conditions at the appointed liftoff time of the SpaceX-3 mission – roughly the time when the Earth’s rotation moves the rocket into the plane of the space stations orbit.

Meteorologists with the U.S. Air Force 45th Weather Squadron are predicting a significant chance of rain showers and thunderstorms in the Florida Space coast launch area that could violate three launch rules, namely the Thick Cloud, Lightning and Flight Through Precipitation rules.

In the event of a scrub for any reason on Friday, NASA, SpaceX and Air Force managers approved another backup launch opportunity on Saturday, April 19 at 3:02:42 p.m.

The weather outlook for a Saturday liftoff improves somewhat to 60 percent “GO”.

Originally, Monday and Friday were the only available launch target dates this week.

Assuming a successful Falcon 9 launch on Friday, station crew members Rick Mastracchio and Steven Swanson will grapple the Dragon cargo freighter with the 57 foot long Canadarm2 on Easter Sunday morning, April 20, at 7:14 a.m. at then berth it at the Earth-facing port of the Harmony module.

Monday’s launch attempt was scrubbed about an hour before liftoff when SpaceX mission controllers and engineers detected that a helium valve in the pneumatic system for stage separation between the first and second stages was not holding the specified pressure.

The success of the mission was therefore dependent on the perfect operation of a backup check valve for the stage separation pistons.

Although no technical issues were detected with the backup valve, the anamolous situation violated SpaceX launch rules.

“SpaceX policy is not to launch with any known anomalies,” said SpaceX in a statement.

The erect Falcon 9 was lowered back to the horizontal position so that SpaceX engineers could swap out the faulty helium valve, as well as conduct a complete inspection of the rocket to look for signs of any other issues that may have contributed to the valve not working as designed, said SpaceX.

This unmanned SpaceX mission dubbed CRS-3 will deliver some 5000 pounds of science experiments, a pair of hi tech legs for Robonaut 2, a high definition imaging camera suite, an optical communications experiment (OPALS) and essential gear, the VEGGIE lettuce growing experiment, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

To date SpaceX has completed two operational cargo resupply missions and a test flight. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

NASA awarded contracts to SpaceX and competitor Orbital Sciences to develop unmanned cargo freighters via CRS to restore US capability to resupply the ISS following the shutdown of the space shuttle program in 2011.

SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights through 2016 at a cost of about $1.6 Billion.

The next launch of Orbital Sciences Antares/Cygnus commercial rocket to the ISS from NASA Wallops, VA, is tentatively slated for May 6. But the target date hinges on when this SpaceX-3 mission actually flies and could slip into mid-June.

The keys to NASA’s historic launch Pad 39A that propelled humanity’s first man to walk on the Moon – Neil Armstrong – during the history making flight of Apollo 11, have been handed over to new owners, namely the private aerospace firm SpaceX for a new purpose – serving as a commercial launch facility.

NASA and Space Exploration Technologies Corporation (SpaceX) of Hawthorne, Calif., have just signed an agreement giving SpaceX rights to occupy and operate seaside Launch Complex 39A at the Kennedy Space Center (KSC) in Florida.

SpaceX was founded by billionaire, entrepreneur and space visionary Elon Musk.

SpaceX aims to give the now dormant pad a new lease on life in the emerging New Space era by revitalizing it as a commercial launch site for the company’s mammoth new Falcon Heavy rocket, currently under development, as well as for manned launches of the firm’s human rated Dragon spacecraft atop the Falcon 9 according to Gwynne Shotwell, president of SpaceX.

“We’ll make great use of this pad, I promise,” Shotwell told reporters at a briefing at the pad.

The liquid fueled Falcon Heavy will be the most powerful rocket in the world according to SpaceX, generating generating nearly four million pounds of liftoff thrust from 27 engines and thus significantly exceeding the power of the Delta IV Heavy manufactured by competitor United Launch Alliance.

Shotwell said renovations to pad 39A would start later this year. The maiden SpaceX launch from the complex is expected next year.

“We will launch the Falcon Heavy from here from this pad early next year,” Shotwell stated.

The SpaceX Dragon is one of three commercial crew vehicles being developed under a public-private partnership with NASA to ferry US astronauts to the International Space Station (ISS) and restore America’s human spaceflight capability lost since the shuttle’s retirement.

The Boeing CST-100 and Sierra Nevada Dream Chaser are also vying for the next round of private ‘space taxi’ funding from NASA.

Pad 39A has been inactive and mothballed since the last shuttle mission, STS-135, thundered to space in July 2011.

Not a single rocket has rolled up the ramp at KSC in nearly 3 years.

The new lease agreement was signed by NASA and SpaceX officials and announced onsite at Pad 39 at the briefing.

“Today this historic site from which numerous Apollo and space shuttle missions began and from which I first flew and left the planet on STS-61C on Columbia, is beginning a new mission as a commercial launch site,” said NASA Administrator Charles Bolden.

“While SpaceX will use pad 39A at Kennedy, about a mile away on pad 39B, we’re preparing for our deep space missions to an asteroid and eventually Mars. The parallel pads at Kennedy perfectly exemplify NASA’s parallel path for human spaceflight exploration — U.S. commercial companies providing access to low-Earth orbit and NASA deep space exploration missions at the same time.”

Under terms of the new agreement with NASA, the lease with SpaceX spans 20 years.

“It’s exciting that this storied NASA launch pad is opening a new chapter for space exploration and the commercial aerospace industry,” said Bolden.

SpaceX will also maintain and operate Pad 39A at its own expense, with no US federal funding from NASA.

Pad 39A will be SpaceX’s third launch site. The company also launches its Falcon 9 rockets from nearby Pad 40 on Cape Canaveral Air Force Station and a west coast pad on Vandenberg Air Force Base, Calif.

The next Falcon 9 liftoff with an unmanned Dragon cargo freighter is currently slated from Friday, April 18 following Monday’s scrub.

NASA determined that the agency no longer has a use for pad 39A since the end of the shuttle era and has been looking for a new tenant to take over responsibility and pay for maintenance of the launch complex. The agency awarded the lease to SpaceX in December 2013.

Instead, NASA decided to completely upgrade, renovate and modernize Pad 39As twin, namely Launch Pad 39B, and invested in converting it into a 21st Century launch complex.

NASA will use Pad 39B to launch the state of the art Orion crew vehicle atop the new Space Launch System (SLS) booster for voyages beyond Earth and taking humans back to the vicinity of the Moon and further out on deep space missions to Asteroids, Mars and beyond.

The first unmanned SLS test flight from Pad 39B is slated for late 2017.

Pad 39A was an active NASA launch pad for nearly 35 years starting back near the dawn of the Space Age in the 1960s.

Apollo 4 was the first NASA booster to blast off from Pad 39A on Nov. 9, 1967 during the historic inaugural test flight of the Saturn V moon rocket that eventually served to dispatch all six US manned lunar landing missions.

The closing NASA use of Pad 39A took place on July 8, 2011 with the launch of STS-135 and orbiter Atlantis on the final flight of the space shuttle era.

The four person STS-135 crew delivered the last US pressurized module to the massive low-Earth orbiting ISS.

No Americans have launched to space from American soil since STS-135.

Launch Complex 39 was originally constructed to launch the Apollo moon landing missions atop NASA’s Saturn V booster in the 1960s and 1970s. Both pads were later modified to support the Space Shuttle program whose first launch took place in 1981 from pad 39A.

“Kennedy Space Center is excited to welcome SpaceX to our growing list of partners,” Center Director Bob Cabana said. “As we continue to reconfigure and repurpose these tremendous facilities, it is gratifying to see our plan for a multi-user spaceport shared by government and commercial partners coming to fruition.”

Crucial Radar Outage Scrubs US National Security and SpaceX Launches for Several Weeks from Cape Canaveral

CAPE CANAVERAL AIR FORCE STATION, FL – The sudden and unexpected outage of a crucial tracking radar that is mandatory to insure public safety, has forced the scrub of a pair of launches planned for this week from Cape Canaveral, FL, that are vital to US National Security, United Launch Alliance, SpaceX and NASA.

The tracking radar is an absolutely essential asset for the Eastern Range that oversees all launches from Cape Canaveral Air Force Station and the Kennedy Space Center on the Florida Space Coast.

The pair of liftoffs for the National Reconnaissance Office (NRO) and SpaceX/NASA had been slated just days apart on March 25 and March 30.

Urgent repairs are in progress.

Both launches have now been postponed for a minimum of 3 weeks, according to a statement I received from the 45th Space Wing of the US Air Force that controls the critical launch control systems, communications, computers and radar elements.

An Atlas V rocket carrying the super secret NROL-67 intelligence gathering spy satellite for the National Reconnaissance Office and a SpaceX Falcon 9 rocket carrying a Dragon cargo freightor bound for the International Space Station (ISS) were both in the midst of the final stages of intensive pre-launch processing activities this week.

The Eastern range radar was apparently knocked out by a fire on March 24, a short time after the early morning rollout of the United Launch Alliance (ULA) Atlas V rocket to the launch pad at Space Launch Complex 41 on Cape Canaveral.

“An investigation revealed a tracking radar experienced an electrical short, overheating the unit and rendering it inoperable,” according to today’s explanatory statement from the USAF 45th Space Wing.

“The outage resulted in an inability to meet minimum public safety requirements needed for flight, so the launch was postponed.”

A SpaceX spokesperson likewise confirmed to me that their launch was also on hold.

A fully functional tracking radar is an absolute requirement to ensure the success and safety of any launch.

The range radar must also be functioning perfectly in order to destroy the rocket in a split second in the event it veers off course to the nearby heavily populated areas along the Space Coast.

Myself and other space journalists had been working at Pad 41 on March 24 and setting up our remote cameras to capture spectacular up close views of the blastoff that had then been scheduled for March 25.

Insufficient maintenance and antiquated equipment due to a lack of US government funding and investment in infrastructure may be implicated.

The range outage for such an extended period of time reveals a clear vulnerability in US National Security planning.

The Air Force is also looking into the feasibility of reviving an inactive radar as a short term quick fix.

But in order to use the retired backup system, it will also have to re-validated to ensure utility and that all launch control and public safety requirements are fully met.

Simultaneously, the engineering team is recalculating launch trajectories and range requirements.

Such a revalidation process will also require an unknown period of time.

The full impact of putting these two launches on hold for the NRO and SpaceX is not known at this time.

Furthermore, the USAF will need to determine the downstream scheduling impact on the very busy manifest of all of the remaining launches throughout 2014 – averaging more than one per month.

Neither the NRO nor NASA and SpaceX have announced firm new launch dates.

The earliest possible Atlas V launch date appears to be sometime in mid-April, but that assessment can change on a dime.

In the meantime, personnel from the 45th Space Wing will continue to work diligently to repair the range radar equipment as quickly as possible.

ULA engineers also rolled the Atlas V rocket back to its processing hanger until a new launch target date is set.

SpaceX likewise awaits a target launch date for the Dragon CRS-3 cargo mission packed with some 5000 pounds of science experiments and supplies for the six man station crew.

It seems likely that the next Orbital Sciences Antares/Cygnus launch to the ISS will also have to be postponed since Dragon and Cygnus berth at the same station port.

KENNEDY SPACE CENTER, FL – Following last week’s sudden and late in the processing flow postponement of the SpaceX Falcon 9 rocket launch, SpaceX announced a reset of its next cargo mission launch for NASA to the International Space Station (ISS) to a new target date of Sunday, March 30.

The commercially developed Falcon 9 booster and Dragon cargo vessel are slated for a spectacular night time liftoff from Cape Canaveral Air Force Station in Florida at 10:50 p.m. EDT on March 30, SpaceX announced on Friday.

This mission, soaring to space under a resupply contract to NASA, could ignite a revolution in both rocketry and robotics.

The first stage of the Falcon 9 rocket sports a quartet of never before tried landing legs and the Dragon freighter is loaded with a set of lanky legs to enable mobility in space for NASA’s Robonaut 2 standing at the cutting edge of space robotics technology.

Launch preparations were suddenly halted less than 72 hours prior to the then planned March 16 early morning launch because of unspecified technical issues concerning the sudden discovery of “contamination,” sources told me.

“To ensure the highest possible level of mission assurance and allow additional time to resolve remaining open items, the team is taking additional time to resolve open items and ensure SpaceX does everything possible on the ground to prepare for a successful launch,” according to a statement from SpaceX.

Several sources told me that the problem related to “contamination” that was found in the “unpressurized truck section” at the rear of the Dragon spacecraft.

“An unknown contaminant of unknown origin was found on a blanket in the Dragon trunk,” independent sources said to Universe Today soon after the postponement was announced.

“After careful review and analysis, engineering teams representing both the ISS and SpaceX have determined Dragon is ready to fly ‘as-is.’ All parties agree that the particular constituents observed in Dragon’s trunk are in line with the previously defined environments levels and do not impose additional risk to the payloads,” SpaceX announced in a new statement.

With the contamination issues now resolved, the launch is back on track.

NASA Television will air live coverage on Sunday.

In case the launch is delayed, the backup launch opportunity is at 9:39 p.m. Wednesday, April 2.

Altogether, this unmanned SpaceX CRS-3 mission will deliver over 5000 pounds of science experiments, a pair of legs for Robonaut 2, a high definition imaging camera suite, an optical communications experiment and essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.

SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights over the next few years at a cost of about $1.6 Billion.

To date SpaceX has completed two operational cargo resupply missions and a test flight. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.

Following the rescheduled March 30 launch and a series of orbit raising and course corrections over the next two days, Dragon will rendezvous and dock at the Earth facing port on the station’s Harmony module on Wednesday, April 2.
