CAPE CANAVERAL AIR FORCE STATION, FL – Blastoff of an advanced communications satellite for the US Navy is set for early Wednesday morning, Sept. 2, using the most powerful variant of the United Launch Alliance (ULA) Atlas V rocket – following a 48 hour postponement due to terrible weather expected from Tropical Storm Erika, which pounded islands in the Caribbean causing destruction and over 20 deaths.

The threat of strong winds and heavy rains forced Florida Gov. Rick Scott to declare a state of emergency in every county in Florida last Friday that was still in effect as rains doused central Florida on Monday.

ULA decided against rolling the Atlas V rocket out to the seaside pad on Saturday in support of the then planned launch of the Multi-User Objective System satellite on Aug. 31.

Liftoff of the Multi-User Objective System-4 (MUOS-4) satellite for the US Navy is now slated for 5:59 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida, and will be broadcast live.

The launch window extends for 44 minutes from 5:59-6:43 a.m. EDT and the weather outlook is now promising.

US Air Force weather forecasters currently predict a 70% chance of favorable weather conditions for “GO” at launch time on Wednesday morning.

The primary concern is for cumulus clouds.

The unmanned Atlas V expendable rocket will launch in its mightiest configuration known as the Atlas V 551 with five solid rocket boosters augmenting the first stage.
Therefore the predawn liftoff is expected to be absolutely spectacular, resonating with a thunderous roar rising on a huge smoke trail that will light up the darkened skies all around the Florida Space Coast for spectators here and far beyond.

You can watch the launch on your laptop or smart phone since it will be carried live on a ULA webcast: http://www.ulalaunch.com

The ULA webcast starts about 20 minutes before launch.

The launch time moves up 4 minutes in the event of a 24 hour delay. The weather prognosis stands at 70 percent “GO”.

Orbital ATK is on the rebound with return to flight of their Antares rocket slated in early 2016 following the catastrophic launch failure that doomed the last Antares in October 2014 on a resupply mission for NASA to the International Space Station (ISS).

Engineers are making “excellent progress” assembling a modified version of Antares that is currently on track to blast off as soon as March 2016 with the company’s Cygnus resupply ship and resume critical deliveries of research experiments and life sustaining provisions to the multinational crews serving aboard the orbiting outpost.

“We are on track for the next Antares launch in early 2016,” said David Thompson, President and Chief Executive Officer of Orbital ATK in a progress update.

Resuming Antares launches is a key part of the company’s multipronged effort to fulfil their delivery commitments to NASA under the Commercial Resupply Services (CRS) contract.

“The focus all along has been to do everything we can to fulfill our commitments to delivering cargo to the space station for NASA,” Thompson stated.

“After the Antares launch failure last October … our team has been sharply focused on fulfilling that commitment.”

The key milestone was to successfully re-engine Antares with a new type of first stage engine that completely eliminates use of the original AJ26 engines that were refurbished 40 year leftovers – the NK-33 from Russia’s abandoned manned moon landing program.

After the launch failure, Orbital managers decided to ditch the trouble plagued AJ-26 and “re-engineered” the vehicle with the new RD-181 Russian-built engines that were derived from the RD-191.

Orbital ATK holds a Commercial Resupply Services (CRS) contract from NASA worth $1.9 Billion to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware spread out over eight Cygnus cargo delivery flights to the ISS.

NASA has recently supplemented the CRS contract with three additional Cygnus resupply deliveries in 2017 and 2018.

However, the Cygnus missions were put on hold when the third operational Antares/Cygnus flight was destroyed in a raging inferno about 15 seconds after liftoff on the Orb-3 mission from launch pad 0A at NASA’s Wallops Flight Facility on Virginia’s eastern shore.

Until Antares flights can safely resume, Orbital ATK has contracted with rocket maker United Launch Alliance (ULA) to launch a Cygnus cargo freighter atop an Atlas V rocket for the first time, in early December – as I reported here.

The Antares rocket is being upgraded with the new RD-181 main engines powering the modified first stage core structure that replace the troublesome AJ26 engines whose failure caused the Antares Orb-3 launch explosion on Oct. 28, 2014.

“We are making excellent progress in resuming our cargo delivery service to the International Space Station for NASA under the Commercial Resupply Services (CRS) contract,” said company officials.

Orbital ATK engineering teams have been working diligently on “integrating and testing the new RD-181 main engines.”

After engineers finished acceptance testing and certification of the RD-181, the first dual engine set was shipped to Orbital’s Wallops Island integration facility. They arrived in mid-July. A second set is due to arrive in the fall.

“The RD-181 engine provides extra thrust and higher specific impulse, significantly increasing the payload capacity of the Antares rocket. This state-of-the-art propulsion system is a direct adaptation of the RD-191 engine, which completed an extensive qualification and certification program in 2013, accumulating more than 37,000 seconds of total run time,” said Scott Lehr, President of Orbital ATK’s Flight Systems Group, in a statement.

Engineers and technicians have now “integrated the two RD-181 engines with a newly designed and built thrust frame adapter and modified first stage airframe.”

Then they will add new propellant feed lines and first stage avionics systems.

Then comes the moment of truth. A “hot fire” test on the launch pad will be conducted by either the end of 2015 or early 2016 “to verify the vehicle’s operational performance and compatibility of the MARS launch complex.”

“Significant progress has been made in the manufacture and test of the modified hardware components, avionics and software needed to support the new engines,” said Mike Pinkston, Vice President and General Manager of Orbital ATK’s Antares Program.

“We are solidly on track to resume flying Antares in 2016.”

Simultaneously, teams have been working hard to repair the Wallops launch pad which was damaged when the doomed Antares plummeted back to Earth and exploded in a hellish inferno witnessed by thousands of spectators and media including myself.

Repairs are expected to be completed by early 2016 to support a launch tentatively planned for as soon as March 2016.

SpaceX, NASA’s other commercial cargo company under contract to ship supplies to the ISS also suffered a launch failure of with their Falcon 9/Dragon cargo delivery rocket on June 28, 2015.

NASA is working with both forms to restart the critical ISS resupply train as soon as can safely be accomplished.

Cygnus Freighter Arrives at Kennedy as Orbital ATK Ramps Up Station Resupply Recovery Efforts via Atlas V

A commercial Cygnus cargo freighter has just arrived at the Kennedy Space Center (KSC) in Florida to begin intensive processing for a critical mission to deliver some four tons of science experiments and supplies to the International Space Station (ISS) atop an Atlas V rocket in early December – as manufacturer Orbital ATK takes a big step in ramping up activities to fulfill its station resupply commitments and recover from the catastrophic launch failure of the firms Antares rocket last October.

Taking advantage of the built in flexibility to launch Cygnus on a variety of rockets, Orbital ATK quickly contracted rocket maker United Launch Alliance (ULA) to propel the cargo ship as soon as practical on the venerable Atlas V – as Orbital simultaneously endeavors to reengineer the Antares and bring that vehicle back to full flight status in 2016.

Since the fastest and most robust path back to on orbital cargo delivery runs through Florida via an Atlas V, Orbital ATK teamed up with ULA to launch a minimum of one Cygnus with an option for more.

Cygnus is comprised of a pressurized cargo module (PCM) manufactured by Thales Alenia Space’s production facility in Turin, Italy and a service module (SM) manufactured at Orbital ATK’s Dulles, Virginia satellite manufacturing facility.

The PCM arrived on Monday, Aug. 11 and is now being processed for the flight dubbed OA-4 at KSC inside the Space Station Processing Facility (SSPF). After the SM arrives in October it will be mated to the PCM inside the SSPF.

The first Cygnus cargo mission should liftoff sometime late in the fourth quarter of 2015, perhaps as soon as Dec. 3, aboard an Atlas V 401 vehicle from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.

Since ULA’s Atlas V manifest was already fully booked, ULA managers told me that they worked diligently to find a way to manufacture and insert an additional Atlas V into the tight launch sequence flow at the Cape.

And since the station and its six person crews can’t survive and conduct their scientific research work without a steady train of cargo delivery missions from the station’s partner nations, Orbital ATK is “devoting maximum efforts” to get their Antares/Cygnus ISS resupply architecture back on track as fast as possible.

Orbital ATK holds a Commercial Resupply Services (CRS) contract from NASA worth $1.9 Billion to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware for eight Cygnus cargo delivery flights to the ISS.

However, the Cygnus missions were put on hold when the third operational Antares/Cygnus flight was destroyed in a raging inferno about 15 seconds after liftoff on the Orb-3 mission from launch pad 0A at NASA’s Wallops Flight Facility on Virginia’s eastern shore.

“We committed to NASA that we would resume CRS cargo delivery missions as soon as possible under a comprehensive ‘go-forward’ plan after the Antares launch failure last October,” said David W. Thompson, President and Chief Executive Officer of Orbital ATK.

“Since that time our team has been sharply focused on fulfilling that commitment. With a Cygnus mission slated for later this year and at least three missions to the Space Station planned in 2016, we are on track to meet our CRS cargo requirements for NASA.”

Orbital says they will deliver the full quantity of cargo specified in the CRS contract with NASA.

“Our team and our partners are devoting maximum efforts to ensuring the success of NASA’s ISS commercial cargo program.”

“We are committed to meeting all CRS mission requirements, and we are prepared to continue to supply the Space Station.”

For the OA-4 cargo mission, Cygnus will be loaded with its heaviest cargo to date on nearly four tons.

The weightier cargo is possible because a longer version of Cygnus will be employed.

This mission will fly with the extended Cygnus Pressurized Cargo Module (PCM) which will carry approximately 3,500 kg or 7,700 pounds of supplies to station.

“This is a very exciting time for the Cygnus team at Orbital ATK,” said Frank DeMauro, vice president of Human Space Systems and program director of the Commercial Resupply Services program at Orbital ATK.

“Not only are we launching from Kennedy on an Atlas V for the first time, but this will also be the first flight of the Enhanced Cygnus, which includes a larger cargo module and a more mass-efficient service module.”

Use of the enhanced Cygnus in combination with the added thrust ULA V is a game changer enabling the Cygnus to carry its maximum possible cargo load for NASA.

“During our first three missions, we delivered 3,629 kilograms to the space station, about the weight of two F-150 pickup trucks,” said Frank DeMauro.

The OA-4 Cygnus alone will deliver some 3,500 kilograms.

Once in orbit, Cygnus fires its onboard thrusters to precisely guide itself close to the space station so that the astronauts can grapple it with the robotic arm and berth it to a port on the station.

CAPE CANAVERAL AIR FORCE STATION, FL – An advanced military communications satellite that will significantly fortify tactical communications amongst U.S. and allied military forces took flight this evening, July 23, during a stunning sunset blastoff of a United Launch Alliance Delta IV rocket from the Florida space coast as threatening weather luckily skirted away from the launch site in the waning hours of the countdown.

The United Launch Alliance (ULA) Delta IV rocket successfully launched the Wideband Global SATCOM-7 (WGS-7) communications satellite for the U.S. Air Force at 8:07 p.m. EDT Thursday evening, July 23, from Space Launch Complex-37 on Cape Canaveral Air Force Station, Florida.

The evening hues in the sunset skies over the launch pad region were stellar and wowed spectators all along the space coast region.

The Wideband Global SATCOM system provides “anytime, anywhere communication” for allied military forces “through broadcast, multicast and point to point connections,” according to ULA.

The $570 million WGS 7 satellite is part of a significant upgraded constellation of high capacity communications satellites providing enhanced communications capabilities to American and allied troops in the field for the coming two decades.

“WGS provides essential communications services, allowing Combatant Commanders to exert command and control of their tactical forces, from peace time to military operations.”

Following a one day launch postponement forced by drenching rainstorms, widespread thunderstorms and heavy winds on Wednesday, the initial outlook for Thursdays weather looked at first like it would repeat the dismal weather conditions in the central Florida region and cause another scrub.

Luckily the forecast storms relented and heavy rains and thunder passed through the launch pad area earlier enough in the day that technicians for rocket provider ULA were able to fuel the rocket as planned with cryogenic propellants starting around four hours before the liftoff.

WGS-7 is the seventh in a series of high capacity that will broaden tactical communications for U.S. and allied forces at both a significantly higher capacity and lower cost.

The Boeing built WGS-7 will provide the U.S. and allied militaries with 17 percent more secure communications bandwidth. It is also the only military satellite communications system that can support simultaneous X and Ka band communications.

“Every WGS that we deliver increases the ability of U.S. and allied forces to reliably transmit vital information,” said Dan Hart, Boeing vice president, Government Satellite Systems.

It sent signals confirming its health soon after launch.

Altogether Boeing is manufacturing 10 WGS satellites for the U.S. Air Force.

The WGS payload bandwidth will be enhanced even more for the last three satellites in the WGS series. To further improve connectivity the payload bandwidth will double for WGS-8.

Boeing also promises big cost reductions on the last four WGS satellites by instituting additional commercial manufacturing procedures.

“By utilizing commercial processes, we are able to offer greater capacity at a lower spacecraft cost, resulting in more than $150 million in savings for WGS-7 through WGS-10,” noted Hart.

Tonight’s spectacular liftoff was the second successful ULA launch in just eight days from Cape Canaveral. Last week a ULA Atlas V launched the latest GPS satellite for the USAF.

The WGS launch also marked ULA’s seventh launch in 2015. Overall this was ULA’s 98th successful one-at-a-time launch since the company was formed in December 2006 as a joint venture between Lockheed and Boeing.

“Kudos to the Air Force and all of our mission partners on today’s successful launch and orbital delivery of the WGS-7 satellite. The ULA team is honored work with these premier U.S. government and industry mission teammates and to contribute to the WGS enhanced communications capabilities to the warfighter,” said Jim Sponnick, ULA vice president, Atlas and Delta Programs.

“The team continues to emphasize reliability, and one launch at a time focus on mission success to meet our customer’s needs.”

The Delta IV Medium+ rocket launched in a 5,4 configuration with a 5-meter diameter composite payload fairing built by Orbital ATK and with four solid rocket motors augmenting the first stage common booster core powered by a single RS-68A main engine. Each of the 60 inch diameter GEM-60 solids from Orbital ATK produces about 200,000 lbs of thrust.

This was the first flight of the Delta IV with the newly upgraded RS-68 engine.

The Aerojet Rocketdyne RS-68A first stage main engine burns cryogenic liquid hydrogen and liquid oxygen which generates about 702,000 lbf of thrust at sea level. The upper stage was powered by an Aerojet Rocketdyne RL10B-2 engine

“The modified nozzle on the RS-68A supports a 17% increase in engine performance,” Andrew Haaland of Orbital ATK told Universe today at the media viewing site.

CAPE CANAVERAL AIR FORCE STATION, FL – A high powered military communications satellite for the US Air Force is now slated for launch on a United Launch Alliance (ULA) Delta IV rocket on Thursday evening, July 23, following a scrub called on Wednesday due to powerful thunderstorms passing too close to the Cape Canaveral launch pad in Florida.

Heavy rain and thunderstorms within range of the Delta IV launch pad at Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida, forced ULA to scrub the blastoff originally set for Wednesday, July 22.

Due to deteriorating weather, ULA technicians were had to stop processing the rocket for launch and were unable to fuel the propellant tanks. Predicted high winds were also a factor in the launch scrub.

The Delta IV liftoff with the Wideband Global SATCOM 7 (WGS 7) satellite was reset for Thursday, July 23, at 8:07 p.m. EDT

The window extends for 39 minutes until 8:46 p.m. EDT.

You can watch the Delta launch live on a ULA webcast that starts at 7:47 p.m. EDT here:

“WGS enables more robust and flexible execution of Command and Control, Communications, Computers, Intelligence,Surveillance and Reconnaissance (C4ISR), as well as battle management and combat support information functions,” according to ULA.

The Delta IV Medium+ rocket will launch in a 5,4 configuration with a 5-meter diameter payload fairing and four solid rocket motors augmenting the first stage core powered by a single RS-68 main engine.

The RS-68 burns cryogenic liquid hydrogen and liquid oxygen which generates about 702,000 lbf of thrust at sea level.

The in-flight failure of a critical support strut inside the second stage liquid oxygen tank holding a high pressure helium tank in the Falcon 9 rocket, is the likely cause of the failed SpaceX launch three weeks ago on June 28, revealed SpaceX CEO and chief designer Elon Musk during a briefing for reporters held today, July 20, to explain why the critical cargo delivery run for NASA to the space station suddenly turned into a total disaster after a promising start.

The commercial booster and its cargo Dragon payload were unexpectedly destroyed by an overpressure event 139 seconds after a picture perfect blastoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on June 28 at 10:21 a.m. EDT.

Musk emphasized that the failure analysis is still “preliminary” and an “initial assessment” based on the investigation thus far. SpaceX has led the investigation efforts under the oversight of the FAA with participation from prime customers NASA and the U.S. Air Force.

The root cause appears to be that the second stage strut holding the high pressure helium tank inside the 2nd stage broke at a bolt – far below its design specification and thereby allowing the tank to break free and swing away.

“The strut that we believe failed was designed and certified to handle 10,000 lbs of force, but failed at 2,000 lbs, a five-fold difference,” Musk explained.

“During acceleration of the rocket to 3.2 G’s, the strut holding down the helium tank failed. Helium was released, causing the over pressurization event.”

To date no other issues have been identified as possible failure modes, Musk elaborated.

The helium tanks are pressurized to 5500 psi and were breached during the over pressurization. The purpose of the helium tanks is to pressurize the first and second stage propellant tanks.

“We tested several hundred struts. On the outside they looked normal. But inside there was a problem,” Musk explained

“Detailed close-out photos of stage construction show no visible flaws or damage of any kind,” according to a SpaceX statement.

The struts are produced by an outside vendor that Musk would not identify. He added that in the future, SpaceX will likely choose a different vendor to manufacture the struts.

He said the struts were made from a type of stainless steel and would also likely be redesigned.

“The material of construction will be changed to Inconel,” Musk told me in response to a question.

Hundreds of the original type struts have been used to date on the first and second stages of the Falcon 9 with no issues. In the future, they will also be independently certified for use, by an outside contractor instead of the vendor.

The nine first stage Merlin 1D engines of the Falcon 9 were still firing nominally during the start of the mishap, said Musk. The first stage had nearly completed its planned firing duration when the explosion took place.

“The event happened very quickly, within 0.893 seconds,” Musk stated, from the first indication of an issue to loss of all telemetry.

“Preliminary analysis suggests the overpressure event in the upper stage liquid oxygen tank was initiated by a flawed piece of support hardware (a “strut”) inside the second stage,” noted SpaceX in a statement.

The blastoff of the Dragon CRS-7 cargo mission for NASA was the first failure of the SpaceX Falcon 9 rocket after 18 straight successes and the firms first launch mishap since the failure of a Falcon 1 in 2008.

The SpaceX CRS-7 Dragon was loaded with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.

The Dragon cargo freighter survived the explosion but was destroyed when it impacted the Atlantic Ocean.

“But the Dragon might have been saved if the parachutes had been deployed,” said Musk.

Unfortunately the software required to deploy the parachute was not loaded onboard.

“The new software required to deploy the parachutes will be included on all future Dragons, V1 and V2,” said Musk, referring to the cargo and crew versions of the SpaceX Dragon spaceship.

The NASA cargo was valued at about $110 million. The launch itself was not insured.

The investigation board is reviewing data from over 3,000 telemetry channels as well as video and physical debris, he noted.

The next launch of a Falcon 9 will be postponed at least a few months until “no earlier than September” Musk indicated.

Two Falcon 9 launches had been set for August from Vandenberg AFB and Cape Canaveral. And the next launch to the ISS had been slated for September on the Dragon CRS-8 mission.

Musk said the next payload to be launched aboard a Falcon 9 has yet to be determined.

Starting in 2017, the Falcon 9 will launch astronauts to the ISS aboard the Crew Dragon.

Overall CRS-7 was the seventh SpaceX commercial resupply services mission and the eighth trip by a Dragon spacecraft to the station since 2012.

CRS-7 marked the company’s seventh operational 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 station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s original Commercial Resupply Services (CRS) contract.

NASA Names Four Astronauts for First Boeing, SpaceX U.S. Commercial Spaceflights

NASA has selected experienced astronauts Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams to work closely with The Boeing Company and SpaceX to develop their crew transportation systems and provide crew transportation services to and from the International Space Station. Credits: NASA

NASA today (July 9) named the first four astronauts who will fly on the first U.S. commercial spaceflights in private crew transportation vehicles being built by Boeing and SpaceX – marking a major milestone towards restoring American human launches to U.S. soil as soon as mid-2017, if all goes well.

The four astronauts chosen are all veterans of flights on NASA’s Space Shuttles and to the International Space Station (ISS); Robert Behnken, Eric Boe, Douglas Hurley and Sunita Williams. They now form the core of NASA’s commercial crew astronaut corps eligible for the maiden test flights on board the Boeing CST-100 and Crew Dragon astronaut capsules.

Behnken, Boe and Hurley have each launched on two shuttle missions and Williams is a veteran of two long-duration flights aboard the ISS after launching on both the shuttle and Soyuz. All four served as military test pilots prior to being selected as NASA astronauts.

The experienced quartet of space flyers will work closely with Boeing and SpaceX as they begin training and prepare to launch aboard the first ever commercial ‘space taxi’ ferry flight missions to the ISS and back – that will also end our sole source reliance on the Russian Soyuz capsule for crewed missions to low-Earth orbit and further serve to open up space exploration and transportation services to the private sector.

Boeing and SpaceX were awarded contracts by NASA Administrator Charles Bolden in September 2014 worth $6.8 Billion to complete the development and manufacture of the privately developed CST-100 and Crew Dragon astronaut transporters under the agency’s Commercial Crew Transportation Capability (CCtCap) program and NASA’s Launch America initiative.

“I am pleased to announce four American space pioneers have been selected to be the first astronauts to train to fly to space on commercial crew vehicles, all part of our ambitious plan to return space launches to U.S. soil, create good-paying American jobs and advance our goal of sending humans farther into the solar system than ever before,” said NASA Administrator Charles Bolden, in a statement.

“These distinguished, veteran astronauts are blazing a new trail — a trail that will one day land them in the history books and Americans on the surface of Mars.”

The selection of astronauts for rides with NASA’s Commercial Crew Program (CCP) comes almost exactly four years to the day since the last American manned space launch of Space Shuttle Atlantis on the STS-135 mission to the space station on July 8, 2011 from the Kennedy Space Center in Florida.

Hurley was a member of the STS-135 crew and served as shuttle pilot under NASA’s last shuttle commander, Chris Ferguson, who is now Director of Boeing’s CST-100 commercial crew program. Read my earlier exclusive interviews with Ferguson about the CST-100 – here and here.

Since the retirement of the shuttle orbiters, all American and ISS partner astronauts have been forced to hitch a ride on the Soyuz for flights to the ISS and back, at a current cost of over $70 million per seat.

“Our plans to return launches to American soil make fiscal sense,” Bolden elaborated. “It currently costs $76 million per astronaut to fly on a Russian spacecraft. On an American-owned spacecraft, the average cost will be $58 million per astronaut.

Behnken, Boe, Hurley and Williams are all eager to work with the Boeing and SpaceX teams to “understand their designs and operations as they finalize their Boeing CST-100 and SpaceX Crew Dragon spacecraft and operational strategies in support of their crewed flight tests and certification activities as part of their contracts with NASA.”

Until June 2015, Williams held the record for longest time in space by a woman, accumulating 322 days in orbit. Behnken is currently the chief of the astronaut core and conducted six space walks at the station. Boe has spent over 28 days in space and flew on the final mission of Space Shuttle Discovery in Feb. 2011 on STS-133.

The first commercial crew flights under the CCtCAP contract could take place in 2017 with at least one member of the two person crews being a NASA astronaut – who will be “on board to verify the fully-integrated rocket and spacecraft system can launch, maneuver in orbit, and dock to the space station, as well as validate all systems perform as expected, and land safely,” according to a NASA statement.

The second crew member could be a company test pilot as the details remain to be worked out.

The actual launch date depends on the NASA budget allocation for the Commercial Crew Program approved by the US Congress.

Congress has never approved NASA’s full funding request for the CCP program and has again cut the program significantly in initial votes this year. So the outlook for a 2017 launch is very uncertain.

Were it not for the drastic CCP cuts we would be launching astronauts this year on the space taxis.

“Every dollar we invest in commercial crew is a dollar we invest in ourselves, rather than in the Russian economy,” Bolden emphasizes about the multifaceted benefits of the commercial crew initiative.

Under the CCtCAP contract, NASA recently ordered the agency’s first commercial crew mission from Boeing – as outlined in my story here. SpaceX will receive a similar CCtCAP mission order later this year.

At a later date, NASA will decide whether Boeing or SpaceX will launch the actual first commercial crew test flight mission to low Earth orbit.

“This is a new and exciting era in the history of U.S. human spaceflight,” said Brian Kelly, director of Flight Operations at NASA’s Johnson Space Center in Houston, in a statement.

“These four individuals, like so many at NASA and the Flight Operations Directorate, have dedicated their careers to becoming experts in the field of aeronautics and furthering human space exploration. The selection of these experienced astronauts who are eligible to fly aboard the test flights for the next generation of U.S. spacecraft to the ISS and low-Earth orbit ensures that the crews will be well-prepared and thoroughly trained for their missions.”

Both the CST-100 and Crew Dragon will typically carry a crew of four NASA or NASA-sponsored crew members, along with some 220 pounds of pressurized cargo. Each will also be capable of carrying up to seven crew members depending on how the capsule is configured.

The spacecraft will be capable to remaining docked at the station for up to 210 days and serve as an emergency lifeboat during that time.

The NASA CCtCAP contracts call for a minimum of two and a maximum potential of six missions from each provider.

The station crew will also be enlarged to seven people that will enable a doubling of research time.
The CST-100 will be carried to low Earth orbit atop a man-rated United Launch Alliance Atlas V rocket launching from Cape Canaveral Air Force Station, Florida. It enjoys a 100% success rate.

Boeing will first conduct a pair of unmanned and manned orbital CST-100 test flights earlier in 2017 in April and July, prior to the operational commercial crew rotation mission to confirm that their capsule is ready and able and met all certification milestone requirements set by NASA.

The Crew Dragon will launch atop a SpaceX Falcon 9 rocket. It enjoyed a 100% success rate until last weeks launch on its 19th flight which ended with an explosion two minutes after liftoff from Cape Canaveral on June 28, 2015.

SpaceX conducted a successful Pad Abort Test of the Crew Dragon on May 6, as I reported here. The goal was to test the spacecrafts abort systems that will save astronauts lives in a split second in the case of a launch emergency such as occurred during the June 28 rocket failure in flight that was bound for the ISS with the initial cargo version of the SpaceX Dragon.

SpaceX plans an unmanned orbital test flight of Crew Dragon perhaps by the end of 2016. The crewed orbital test flight would follow sometime in 2017.

KENNEDY SPACE CENTER, FL – The root cause of Sundays (June 28) devastating launch failure of the commercial SpaceX Falcon 9 rocket is “still unknown” says SpaceX CEO and founder Elon Musk, following the loss of the NASA contracted resupply mission carrying crucial gear and research experiments to the crew serving aboard the Earth orbiting International Space Station (ISS).

Meanwhile, search and recovery teams from SpaceX and the Coast Guard are scouring the ocean and beaches along the Florida Space Coast for any signs of potentially dangerous Falcon rocket debris that rained down from the sky into the Atlantic Ocean after the sudden explosion unexpectedly destroyed the vehicle barely two minutes after a sun drenched liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida at 10:21 a.m. EDT.

All appeared normal as the Falcon 9 booster and Dragon resupply spaceship were streaking skywards through majestically blue Florida skies when catastrophe struck at approximately 148 seconds after blastoff and the rocket exploded violently- utterly destroying the rocket ship and its two ton load of critical supplies heading to the astronauts and cosmonauts living on board the ISS.

The upper stage appeared to break up in flight as the nine first stage Merlin 1D engines were firing as planned and the rocket was arcing over.

But why that happened and the vehicle disintegrated in mere seconds is still a mystery which will take some time to resolve.

“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds,” tweeted SpaceX CEO Elon Musk.

Although the cause is unknown, Musk also announced that the failure might be related to a problem with the Falcon 9 upper stage. since the first stage engines were still firing as planned.

“There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause,” tweeted Musk.

The rocket was traveling about 5000 km/h at an altitude of 45 kilometers at the time of the mishap.

“Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data,” tweeted SpaceX CEO Elon Musk soon after the explosion.

The pressurized section of the Dragon was packed with over 4,000 pounds of research experiments, spare parts, gear, high pressure supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45 on the ISS.

Sunday’s launch was the 19th launch of the Falcon 9 rocket and the first failure after 18 straight successes.

SpaceX formed a failure investigation board immediately following the launch failure of the SpaceX Commercial Resupply Services 7 (CRS-7) mission bound for the ISS. The FAA and NASA will assist in the investigation.

The launch was the sixth for SpaceX this year, which had been picking up its launch pace dramatically compared to 2014.

It was the third launch failure of a cargo delivery run to the space station in the past half year -including both American and Russian rockets.

The Orbital Sciences Antares/Cygnus Orb 3 mission exploded in a massive an frightening fireball on October 28, 2014 which I witnessed from the press site from NASA Wallops in Virginia.

The Russian Soyuz/Progress 59 mission failed after the cargo vessel separated from the booster rockets third stage and spun wildly out of control in April 2015 and eventually crashed.

Genesis of ULA’s New Vulcan Rocket Borne of Fierce Commercial and Political Pressures: Interview

Fierce commercial and international political pressures have forced the rapid development of the new Vulcan launcher family recently announced by rocket maker United Launch Alliance (ULA). Vulcan’s “genesis” and development was borne of multiple unrelenting forces on ULA and is now absolutely essential and critical for its “transformation and survival in a competitive environment” moving forward, according to Dr. George Sowers, ULA Vice President for Advanced Concepts and Technology, in an exclusive interview with Universe Today.

“To be successful and survive ULA needs to transform to be more of a competitive company in a competitive environment,” Dr. Sowers told Universe Today in a wide ranging interview regarding the rationale and goals of the Vulcan rocket.

Vulcan is ULA’s next generation rocket to space and slated for an inaugural liftoff in 2019.

Faced with the combined challenges of a completely changed business and political environment emanating powerfully from new space upstart SpaceX offering significantly reduced launch costs, and continuing uncertainty over the future supply of the Russian-made RD-180 workhorse rocket engines that power ULA’s venerable Atlas V rocket, after Russia’s annexation of Crimea, Sowers and ULA’s new CEO Tory Bruno were tasked with rapidly resolving these twin threats to the firms future well being – which also significantly impacts directly on America’s national security.

“Our current plan is to have the new Vulcan rocket flying by 2019,” Sowers stated.

Whereas ULA enjoyed a virtual US launch monopoly for many years, those days are now history thanks to SpaceX.

The Vulcan launcher was created in response to the commercial SpaceX Falcon 9 rocket, and it will combine the best features of ULA’s existing unmanned Atlas V and Delta IV booster product lines as well as being revamped with new and innovative American-made first stage engines that will eventually be reusable.

It will meet and exceed the capabilities of ULA’s current stable of launchers, including the Delta IV Heavy which recently launched NASA’s maiden Orion crew module on an unmanned test flight in Dec. 2014.

“We at ULA were faced with how do we take our existing products and transform them into a single fleet that enables us to do the entire range of missions on just one family of rockets.”

“So that was really the genesis of what we now call the “Vulcan” rocket. So this single family will be able to do everything [from medium to heavy lift],” Sowers told me.

Another requirement is that Vulcan’s manufacturing methodology be extremely efficient, slashing costs to make it cost competitive with the Space X Falcon 9. Sowers said the launcher would sell “for less than $100 million” at the base level.

“Vulcan will be the highest-performing, most cost-efficient rocket on the market. It will open up new opportunities for the nation’s use of space,” says ULA CEO Tory Bruno.

In its initial configuration Vulcan’s first stage will be powered by a revolutionary new class of cost effective and wholly domestic engines dubbed the BE-4, produced by Blue Origin.

It can be augmented by up to six solid rocket boosters, to propel high value payloads on missions ranging from low Earth orbit to interplanetary destinations for NASA, private industry and vital US national security interests.

Vulcan will also blast off with astronaut crews aboard the Boeing CST-100 space taxi bound for the International Space Station (ISS) in the early 2020s.

Further upgrades including a powerful new upper stage called ACES, will be phased in down the road as launches of ULA’s existing rocket families wind down, to alleviate any schedule slips.

“Because rocket design is hard and the rocket business is tough we are planning an overlap period between our existing rockets and the new Vulcan rocket,” Sowers explained. “That will account for any delays in development and other issues in the transition process to the new rocket.”

ULA was formed in 2006 as a 50:50 joint venture between Lockheed Martin and Boeing that combined their existing expendable rocket fleet families – the Atlas V and Delta IV – under one roof.

Development of the two Evolved Expendable Launch Vehicles (EELV’s) was originally funded by the U.S. Air Force to provide two independent and complimentary launch capabilities thereby offering assured access to space for America’s most critical military reconnaissance satellites gathering intelligence for the National Reconnaissance Office (NRO), DOD and the most senior US military and government leaders.

Since 2006, SpaceX (founded by billionaire Elon Musk) has emerged on the space scene as a potent rival offering significantly lower cost launches compared to ULA and other launch providers in the US and overseas – and captured a significant and growing share of the international launch market for its American-made Falcon rocket family.

And last year to top that all off, Russia’s deputy prime minister, Dmitry Rogozin, who is in charge of space and defense industries, threatened to “ban Washington from using Russian-made [RD-180] rocket engines [used in the Atlas V rocket], which the US has used to deliver its military satellites into orbit.”

“ULA was formed eight years ago as a government regulated monopoly focused on US government launches. Now eight years later the environment is changing,” Sowers told me.

How did ULA respond to the commercial and political challenges and transform?

“So there are a lot of things we had to do structurally to make that transformation. One of the key ones is that when ULA was formed, the government was very concerned about having assured access to space for national security launches,” Sowers explained.

“In their mind that meant having two independent rocket systems that could essentially do the same jobs. So we have both the Atlas V and the Delta IV. But in a competitive environment you can well imagine that that requirement drives your costs significantly higher than they need to be.”

ULA actually offered three rocket families after the merger, when only one was really needed.

“So our first conclusion on how to be competitive was how do we go from supporting three rocket families – including the Delta II – off of 6 launch pads, to our ultimate aim of getting down to just 1 rocket family of off just 2 pads – one on each coast. So, that is the most cost effective structure that we could come up with and the most competitive.”

Developing a new first stage engine not subject to international tensions was another primary impetus.

“The other big objective that was always in our minds, but that became much higher priority in April 2014 when Russia decided to annex Crimea, is that the RD-180 rocket engine that became our workhorse on Atlas, now became politically untenable.”

“So the other main objective of Vulcan is to re-engine [the first stage of] our fleet with an American engine, the Blue Origin BE-4.”

The RD-180’s will be replaced with a pair of BE-4 engines from Blue Origin, the highly secretive aerospace firm founded by Jeff Bezos, billionaire founder of Amazon. The revolutionary BE-4 engines are fueled by liquefied natural gas and liquid oxygen and will produce about 1.1 million pounds of thrust vs. about 900,000 pounds of thrust for the RD-180, a significant enhancement in thrust.

“The Blue Origin BE-4 is the primary engine [for Vulcan]. ULA is co-investing with Blue Origin in that engine.”

Although the BE-4 is ULA’s primary choice to replace the RD-180, ULA is also investing in development of a backup engine, the AR-1 from Aerojet-Rocketdyne, in case the BE-4 faces unexpected delays.

“As I said, rocket development is hard and risky. So we have a backup plan. That is with Aerojet-Rocketdyne and their AR-1. And we are investing in that engine as well.”

More on the Vulcan, BE-4, reusability and more upcoming in part 2.

The U.S. Air Force announced Tuesday that they have certified SpaceX to launch the nations critical and highly valuable national security satellites on the firms Falcon 9 rocket, thereby breaking the decade old launch monopoly held by launch competitor United Launch Alliance (ULA). ULA is a joint venture owned by aerospace giants Boeing and Lockheed Martin.

The Air Force’s goal in approving the SpaceX Falcon 9 booster is aimed at drastically cutting the high cost of access to space by introducing competition in the awarding of military mission launch contacts. The prior contract involved a sole source $11 Billion “block buy” bid for 36 rocket cores from ULA in December 2013 which was legally challenged by SpaceX in April 2014, but eventually settled by SpaceX in an agreement with the USAF earlier this year.

Lieutenant General Samuel Greaves, Commander of the Air Force Space and Missile Systems Center (SMC), announced the long awaited decision on Tuesday, May 26.

The certification milestone came after a grueling two year review process in which the Air Force invested more than $60 million and 150 people to thoroughly review all aspects of the Falcon 9 booster. The review was based on three successful flights by the Falcon 9 v1.1 which first launched in late 2013.

The purpose of certification is to assure that qualified launch providers could meet the challenge of safely, securely and reliably lofting expensive U.S. national security military missions to space and into their intended orbits with full mission capability that are critical for maintaining national defense.

“The SpaceX and SMC teams have worked hard to achieve certification,” said Greaves, Commander of the Air Force Space and Missile Systems Center (SMC) and Air Force Program Executive Officer for Space, in a statement.

“And we’re also maintaining our spaceflight worthiness process supporting the National Security Space missions. Our intent is to promote the viability of multiple EELV-class launch providers as soon as feasible.”

And the competitive launch races “for award of qualified national security space launch missions” between SpaceX and ULA start very soon, within the next month says the USAF.

In June, the Air Force will issue a Request for Proposal (RFP) for GPS III launch services. ULA has three GPS launches in its manifest for 2015.

Of course SpaceX was overjoyed on hearing the certification news.

“This is an important step toward bringing competition to National Security Space launch, said Elon Musk, SpaceX CEO and Lead Designer.

‘We thank the Air Force for its confidence in us and look forward to serving it well.”

Until today, ULA has held a launch monopoly over military missions since the company was founded in 2006. ULA also launches many NASA science missions, but very few commercial satellites.

Thus the U.S. military and NASA provide the core of ULA’s business and the source of much of its income and profits.

“This is a very important milestone for the Air Force and the Department of Defense,” said Secretary of the Air Force Deborah Lee James, in a statement.

“SpaceX’s emergence as a viable commercial launch provider provides the opportunity to compete launch services for the first time in almost a decade. Ultimately, leveraging of the commercial space market drives down cost to the American taxpayer and improves our military’s resiliency.”

Other military spacecraft in the future could involve vehicles such as the X-37B space plane which recently launched on an Atlas V, as well as weather satellites, signals intelligence and missile warning satellites and a range of top secret missions for the National Reconnaissance Office (NRO) that have been routinely launched by ULA with a 100% success rate to date.

ULA’s stable of launchers includes the Atlas V and Delta IV families of vehicles. ULA is phasing out the Delta IV due to its high costs. Only the Delta IV Heavy will remain in service as required to launch the very heaviest satellites that cannot be accommodated by less powerful rockets.

ULA is also replacing the Atlas V with the partly reusable new Vulcan rocket, that will be phased in starting in 2019 using American-made engines from either Blue Origin or Aerojet Rocketdyne.

The Atlas V uses Russian made RD-180 engines, who’s use has become highly contentious since the deadly crisis in Ukraine erupted in 2014.

The ensuing threats of RD-180 engine embargoes and imposition of sanctions and counter sanctions imposed by the US and Russia have thus placed US national security at risk by being dependent on a rocket with foreign made engines whose future supply chain was uncertain.

U.S. Senator John McCain (R-AZ), Chairman of the Senate Armed Services Committee, has been highly critical of the ULA dependence on the Russian RD-180 engines and issued this statement in response to the Air Force announcement.

“The certification of SpaceX as a provider for defense space launch contracts is a win for competition, said McCain.

“Over the last 15 years, as sole-source contracts were awarded, the cost of EELV was quickly becoming unjustifiably high. I am hopeful that this and other new competition will help to bring down launch costs and end our reliance on Russian rocket engines that subsidizes Vladimir Putin and his cronies.”

Overall the Air Force “invested more than $60 million and 150 people in the certification effort which encompassed 125 certification criteria, including more than 2,800 discreet tasks, 3 certification flight demonstrations, verifying 160 payload interface requirements, 21 major subsystem reviews and 700 audits in order to establish the technical baseline from which the Air Force will make future flight worthiness determinations for launch.”
