America’s premier rocket launch services providerUnited Launch Alliance, or ULA, may be up for sale according to media reports, including Reuters and the Wall Street Journal. Any such sale would result in a major shakeup of the American rocket launching business with far reaching implications.
Aerojet-Rocketdyne has apparently made a bid to buy ULA for approximately $2 Billion in cash, based on behind the scenes information gathered from unnamed sources.
ULA was formed in 2006 as a 50:50 joint venture between aerospace giants Lockheed Martin and Boeing that combined their existing expendable rocket fleet families – the Atlas V and Delta IV – under one roof.
According to Reuters, Aerojet Rocketdyne recently proffered a $2 billion cash offer to buy ULA from Lockheed Martin and Boeing.
“Aerojet Rocketdyne board member Warren Lichtenstein, the chairman and chief executive of Steel Partners LLC, approached ULA President Tory Bruno and senior Lockheed and Boeing executives about the bid in early August,” sources told Reuters.
ULA’s Bruno declined to comment on the story via twitter.
“Wish I could, but as a matter of policy, we don’t comment on this type of story,” Bruno tweeted in response to inquiries.
Since 2006 ULA has enjoyed phenomenal launch success with its venerable fleet of Atlas V and Delta IV rockets and also enjoyed a virtual launch monopoly with the US Government and for the nations most critical national security military payloads.
And just last week, ULA conducted its 99th launch with the successful blastoff of an Atlas V with the MUOS-4 military communications satellite from Cape Canaveral Air Force Station for the U.S. Navy.

Furthermore a Congressional ban on importing the Russian-made RD-180 first stage engines that power the Atlas V rocket, that takes effect in a few years, has threatened the rockets future viability. The Atlas V dependence on Russia’s RD-180’s landed at the center of controversy after Russia invaded Crimea in the spring of 2014.
To date the Atlas V enjoys a 100 percent success rate after over 50 launches.
In response to the Congressional RD-180 engine ban and relentless cost pressures from SpaceX, ULA CEO Tory Bruno and ULA Vice President for Advanced Concepts and Technology George Sowers announced ULA will develop a cost effective new rocket named Vulcan using American made engines.
“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.

However, Lockheed Martin and Boeing are only providing funds to ULA on a quarterly basis to continue development of the Vulcan.
Vulcan’s first stage will most likely be powered by the BE-4 engine being developed by the secretive Blue Origin aerospace firm owned by billionaire Jeff Bezos.
Interestingly, ULA is also evaluating the AR-1 liquid fueled engine being developed by Aerojet-Rocketdyne.
The final decision on which engine to use is expected sometime in 2016.
The engine choice could clearly be impacted if Aerojet-Rocketdyne buys ULA.
Aerojet-Rocketdyne has also sought to buy the rights to manufacture the Atlas V from ULA, which is currently planned to be retired several years after Vulcan is introduced.
To this writer, ULA would seem to be worth far more than $2 Billion. They own manufacturing and rocket launch facilities on both coasts and in several states.

KENNEDY SPACE CENTER, FL – ‘Starliner’ is the new name of America’s next spaceship destined to launch our astronauts to orbit. The new commercial craft from Boeing will restore America’s capability to launch American astronauts from American soil to the International Space Station (ISS) in 2017 – and the magnificent looking first capsule is already taking shape!
Built by The Boeing Company, ‘Starliner’ was officially announced by Boeing and NASA as the new name of the company’s CST-100 commercial crew transportation spacecraft during the Grand Opening event for the craft’s manufacturing facility held at the Kennedy Space Center on Friday, Sept 4. 2015 and attended by Universe Today.
‘Starliner’ counts as history’s first privately developed ‘Space Taxi’ to carry humans to space – along with the Crew Dragon being simultaneously developed by SpaceX.
“Please welcome the CST-100 Starliner,” announced Chris Ferguson, the former shuttle commander who now is deputy manager of operations for Boeing’s Commercial Crew Program, at the Grand Opening event hosting numerous dignitaries.
The CST-100 ‘Starliner’ is at the forefront of ushering in the new commercial era of space flight and will completely revolutionize how we access, explore and exploit space for the benefit of all mankind.
Starliner will be mostly automated for ease of operation and is capable of transporting astronaut crews of four or more to low Earth orbit and the ISS as soon as mid 2017 if all goes well and Congress approves the required funding.
“One hundred years ago we were on the dawn of the commercial aviation era and today, with the help of NASA, we’re on the dawn of a new commercial space era,” said Boeing’s John Elbon, vice president and general manager of Space Exploration.
“It’s been such a pleasure to work hand-in-hand with NASA on this commercial crew development, and when we look back 100 years from this point, I’m really excited about what we will have discovered.”

The CST-100 ‘Starliner’ will be produced in Boeing’s newly revamped manufacturing facility dubbed the Commercial Crew and Cargo Processing Facility (C3PF) on site at the Kennedy Space Center in Florida.
The CC3P building was previously known as Orbiter Processing Facility-2 (OPF-3) and utilized by NASA to process the agency’s space shuttle orbiters between crewed flights during the three decade long Space Shuttle program.
“When Boeing was looking for the prime location for its program headquarters, we knew Florida had a lot to offer from the infrastructure to the supplier base to the skilled work force,” said Chris Ferguson.
“Starliner will launch on an Atlas V from pad 41 at Cape Canaveral Air Force Station in Florida. It has the capability to dock at the ISS within 24 hours. It can stay docked at the station for 6 months.”
Over the past few years, the historic facility has been completely renovated, upgraded and transformed into a state of the art manufacturing site for Boeing’s commercial CST-100 Starliner.

It is also a key part of NASA’s overarching strategy to send Humans on a “Journey to Mars” in the 2030s.
“Commercial crew is an essential component of our journey to Mars, and in 35 states, 350 American companies are working to make it possible for the greatest country on Earth to once again launch our own astronauts into space,” said NASA Administrator Charles Bolden. “That’s some impressive investment.”

The commercial crew program is designed to return human spaceflight launches to the United States and end our sole source reliance on Russia and the Soyuz capsule for all manned flights to the ISS and crew rotation missions.
Since the forced retirement of NASA’s shuttle orbiters in 2011, US astronauts have been totally dependent on the Russians for trips to space and back.
SpaceX also received a NASA award worth $2.6 Billion to build the Crew Dragon spacecraft for launch atop the firms man-rated Falcon 9 rocket.
Final assembly of both half’s of Starliner will take place in the C3PF – namely the crew command module and the service module.
Boeing is already building the first version of Starliner known as the Structural Test Article (STA) . The STA will be used for extensive prelaunch testing and evaluation to ensure it will be ready and robust and capable of safely launches humans to orbit on a very cost effective basis.
The Starliner STA is rapidly taking shape. The first components have been built and were on display at the C3PF Grand Opening eventy of Sept. 4. They are comprised of the upper and lower halves of the crew command module, the crew access tunnel and adapter.
The shell of Starliner’s first service module was also on display.
“The STA will be completed in early 2016,” said John Mulholland Boeing Vice President, Commercial Programs, at the event.
“Then we start assembly of the Qualification Test Article.”
I asked Mulholland to describe the currently planned sequence of Starliner’s initial uncrewed and crewed flights.
“The first uncrewed flight is expected to occur in May 2017. Then comes the Pad Abort Test in August 2017. The first crewed flight is set for September 2017. The first contracted regular service flight (PCM-1) is set for December 2017,” Mulholland told me.
“It’s all very exciting.”

“Kennedy Space Center has transitioned more than 50 facilities for commercial use. We have made improvements and upgrades to well-known Kennedy workhorses such as the Vehicle Assembly Building, mobile launcher, crawler–transporter and Launch Pad 39B in support of Orion, the SLS and Advanced Exploration Systems,” said Robert Cabana, Kennedy’s center director.
“I am proud of our success in transforming Kennedy Space Center to a 21st century, multi-user spaceport that is now capable of supporting the launch of all sizes and classes of vehicles, including horizontal launches from the Shuttle Landing Facility, and spacecraft processing and landing.”

NASA teams are evaluating Orion’s fate under multiple scenarios in case certain of the ships various parachute systems suffer partial deployment failures after the blistering high speed reentry into the Earth’s atmosphere.
Orion is nominally outfitted with multiple different parachute systems including two drogue chutes and three main chutes that are essential for stabilizing and slowing the crewed spacecraft for safely landing in the Pacific Ocean upon concluding a NASA ‘Journey to Mars’ mission.”
This week engineers from NASA and prime contractor Lockheed Martin ran a dramatic and successful six mile high altitude drop test in the skies over the Arizona desert, in the instance where one of the parachutes in each of Orion’s drogue and main systems was intentionally set to fail.
“We test Orion’s parachutes to the extremes to ensure we have a safe system for bringing crews back to Earth on future flights, even if something goes wrong,” says CJ Johnson, project manager for Orion’s parachute system, in a statement.
“Orion’s parachute performance is difficult to model with computers, so putting them to the test in the air helps us better evaluate and predict how the system works.”
Although Orion hits the atmosphere at over 24,000 mph after returning from deep space, it slows significantly after atmospheric reentry.
By the time the first parachutes normally deploy, the crew module has decelerated to some 300 mph. Their job is to slow the craft down to about 20 mph by the time of ocean splashdown mere minutes later.
On Aug. 26, NASA conducted a 35,000 foot high drop test out of the cargo bay of a C-17 aircraft using an engineering test version of the Orion capsule over the U.S. Army Yuma Proving Ground in Yuma, Arizona.
“The engineering model has a mass similar to that of the Orion capsule being developed for deep space missions, and similar interfaces with its parachute system,” say officials.
“Engineers purposefully simulated a failure scenario in which one of the two drogue parachutes, used to slow and stabilize Orion at high altitude, and one of its three main parachutes, used to slow the crew module to landing speed, did not deploy.”
Here’s a video detailing the entire drop test sequence of events from preflight preparations to the parachute landing.
The high-risk Aug. 26 experiment was NASA’s penultimate drop test in this engineering evaluations series. A new series of tests in 2016 will serve to qualify the parachute system for crewed flights.

Orion’s next launch is set for the uncrewed test flight called Exploration Mission-1 (EM-1). It will blast off on the inaugural flight of NASA’s SLS heavy lift monster rocket concurrently under development – from Launch Complex 39-B at the Kennedy Space Center.
The maiden SLS test flight is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.
NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

“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.
Soviet era NK-33 engines refurbished as the AJ26 exactly like pictured here probably caused Antares’ rocket failure on Oct. 28, 2014.

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.

With today’s (Aug. 13) successful test firing of an RS-25 main stage engine for NASA’s Space Launch System (SLS) monster rocket currently under development, the program passed a key milestone advancing the agency on the path to propel astronauts back to deep space at the turn of the decade.
The 535 second long test firing of the RS-25 development engine was conducted on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – and ran for the planned full duration of nearly 9 minutes, matching the time they will fire during an actual SLS launch.
All indications are that the hot fire test apparently went off without a hitch, on first look.
“We ran the full duration and met all test objectives,” said Steve Wofford, SLS engine manager, on NASA TV following today’s’ test firing.
“There were no anomalies.” – based on the initial look.
The RS-25 is actually an upgraded version of former space shuttle main engines that were used with a 100% success rate during NASA’s three decade-long Space Shuttle program to propel the now retired shuttle orbiters to low Earth orbit. Those same engines are now being modified for use by the SLS.

“Data collected on performance of the engine at the various power levels will aid in adapting the former space shuttle engines to the new SLS vehicle mission requirements, including development of an all-new engine controller and software,” according to NASA officials .
The engine controller functions as the “brain” of the engine, which checks engine status, maintains communication between the vehicle and the engine and relays commands back and forth.
The core stage (first stage) of the SLS will be powered by four RS-25 engines and a pair of the five-segment solid rocket boosters that will generate a combined 8.4 million pounds of liftoff thrust, making it the most powerful rocket the world has ever seen.
Since shuttle orbiters were equipped with three space shuttle main engines, the use of four RS-25s on the SLS represents another significant change that also required many modifications being thoroughly evaluated as well.

The SLS will be some 10 percent more powerful than the Saturn V rockets that propelled astronauts to the Moon, including Neil Armstrong, the human to walk on the Moon during Apollo 11 in July 1969.
SLS will loft astronauts in the Orion capsule on missions back to the Moon by around 2021, to an asteroid around 2025 and then beyond on a ‘Journey to Mars’ in the 2030s – NASA’s overriding and agency wide goal.
Each of the RS-25’s engines generates some 500,000 pounds of thrust. They are fueled by cryogenic liquid hydrogen and liquid oxygen. For SLS they will be operating at 109% of power, compared to a routine usage of 104.5% during the shuttle era. They measure 14 feet tall and 8 feet in diameter.
They have to withstand and survive temperature extremes ranging from -423 degrees F to more than 6000 degrees F.
This video shows the full duration hot-fire test:
NASA has 16 of the RS-25s leftover from the shuttle era and they are all being modified and upgraded for use by the SLS rocket.
Today’s test was the sixth in a series of seven to qualify the modified engines to flight status. The engine ignited at 5:01 p.m. EDT and reached the full thrust level of 512,000 pounds within about 5 seconds.
The hot gas was exhausted out of the nozzle at 13 times the speed of sound.
Since the shuttle engines were designed and built over three decades ago, they are being modified where possible with state of the art components to enhance performance, functionality and ease of operation, by prime contractor Aerojet-Rocketdyne of Sacramento, California.
One of the key objectives of today’s engine firing and the entire hot fire series was to test the performance of a brand new engine controller assembled with modern manufacturing techniques.
“Operators on the A-1 Test Stand at Stennis are conducting the test series to qualify an all-new engine controller and put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a SLS mission,” says NASA.
“The new controller, or “brain,” for the engine, which monitors engine status and communicates between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status.’

“The RS-25 is the most complicated rocket engine out there on the market, but that’s because it’s the Ferrari of rocket engines,” says Kathryn Crowe, RS-25 propulsion engineer.
“When you’re looking at designing a rocket engine, there are several different ways you can optimize it. You can optimize it through increasing its thrust, increasing the weight to thrust ratio, or increasing its overall efficiency and how it consumes your propellant. With this engine, they maximized all three.”
Engineers will now pour over the data collected from hundreds of data channels in great detail to thoroughly analyze the test results. They will incorporate any findings into future test firings of the RS-25s.
NASA says that testing of RS-25 flight engines is set to start later this fall.
“The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system for deep space exploration. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time.”
NASA plans to buy completely new sets of RS-25 engines from Aerojet-Rocketdyne taking full advantage of technological advances and modern manufacturing techniques as well as lessons learned from this hot fire series of engine tests.
The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.
The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

On the eve of the 3rd anniversary since her nail biting touchdown inside Gale Crater, NASA’s car sized Curiosity Mars Science Laboratory (MSL) rover has discovered a new type of Martian rock that’s surprisingly rich in silica – and unlike any other targets found before.
Excited by this new science finding on Mars, Curiosity’s handlers are now gearing the robot up for her next full drill campaign today, July 31 (Sol 1060) into a rock target called “Buckskin” – which lies at the base of Mount Sharp, the huge layered mountain that is the primary science target of this Mars rover mission.
“The team selected the “Buckskin” target to drill,” says Lauren Edgar, Research Geologist at the USGS Astrogeology Science Center and an MSL science team member, in a mission update.

For about the past two months, the six wheeled robot has been driving around and exploring a geological contact zone named “Marias Pass” – an area on lower Mount Sharp, by examining the rocks and outcrops with her suite of state-of-the-art science instruments.
The goal is to provide geologic context for her long term expedition up the mountains sedimentary layers to study the habitability of the Red Planet over eons of time.
Data from Curiosity’s “laser-firing Chemistry & Camera (ChemCam) and Dynamic Albedo of Neutrons (DAN), show elevated amounts of silicon and hydrogen, respectively,” in certain local area rocks, according to the team.
Silica is a rock-forming compound containing silicon and oxygen, commonly found on Earth as quartz.
“High levels of silica could indicate ideal conditions for preserving ancient organic material, if present, so the science team wants to take a closer look.”

Therefore the team scouted targets suitable for in depth analysis and sample drilling and chose “Buckskin”.
“Buckskin” is located among some high-silica and hydrogen enriched targets at a bright outcrop named “Lion.”
An initial test bore operation was conducted first to confirm whether that it was indeed safe to drill into “Buckskin” and cause no harm to the rover before committing to the entire operation.
The bore hole is about 1.6 cm (0.63 inch) in diameter.
“This test will drill a small hole in the rock to help determine whether it is safe to go ahead with the full hole,” elaborated Ryan Anderson, planetary scientist at the USGS Astrogeology Science Center and an MSL science team member.
So it was only after the team received back new high resolution imagery last night from the arm-mounted MAHLI camera which confirmed the success of the mini-drill operation, that the “GO” was given for a full depth drill campaign. MAHLI is short for Mars Hand Lens Imager.
“We successfully completed a mini drilling test yesterday (shown in the MAHLI image). That means that today we’re going for the FULL drill hole” Edgar confirmed.
“GO for Drilling.”
So it’s a busy day ahead on the Red Planet, including lots of imaging along the way to document and confirm that the drilling operation proceeds safely and as planned.
“First we’ll acquire MAHLI images of the intended drill site, then we’ll drill, and then we’ll acquire more MAHLI images after drilling,” Edgar explains.
“The plan also includes Navcam imaging of the workspace, and Mastcam imaging of the target and drill bit. In addition to drilling, we’re getting CheMin ready to receive sample in an upcoming plan. Fingers crossed!” Surface observations with the arm-mounted Alpha Particle X-ray Spectrometer (APXS) instrument are also planned.
If all goes well, the robot will process and pulverize the samples for eventual delivery to the onboard pair of miniaturized chemistry labs located inside her belly – SAM and CheMin. Tiny samples will be fed to the inlet ports on the rover deck through the sieved filters.

Meanwhile the team is studying a nearby rock outcrop called “Ch-paa-qn” which means “shining peak” in the native Salish language of northern Montana.”
Anderson says the target is a bright patch on a nearby outcrop. Via active and passive observations with the mast-mounted ChemCam laser and Mastcam multispectral imager, the purpose is to determine if “Ch-paa-qn” is comprised of calcium sulfate like other white veins visible nearby, or perhaps it’s something else entirely.
A rock fragment dubbed “Lamoose” is shown in this picture taken by the Mars Hand Lens Imager (MAHLI) on NASA’s Curiosity rover. Like other nearby rocks in a portion of the “Marias Pass” area of Mt. Sharp, Mars, it has unusually high concentrations of silica. The high silica was first detected in the area by the Chemistry & Camera (ChemCam) laser spectrometer. This rock was targeted for follow-up study by the MAHLI and the arm-mounted Alpha Particle X-ray Spectrometer (APXS). Credits: NASA/JPL-Caltech/MSSS
Before arriving by the “Lion” outcrop last week, Curiosity was investigating another outcrop area nearby, the high-silica target dubbed “Elk” with the ChemCam instrument, while scouting around the “Marias Pass” area in search of tasty science targets for in-depth analysis.
Sometimes the data subsequently returned and analyzed is so extraordinary, that the team decides on a return trip to a spot previously departed. Such was the case with “Elk” and the rover was commanded to do a U-turn to acquire more precious data.
“One never knows what to expect on Mars, but the Elk target was interesting enough to go back and investigate,” said Roger Wiens, the principal investigator of the ChemCam instrument from the Los Alamos National Laboratory in New Mexico.
Soon, ChemCam will have fired on its 1,000th target. Overall the laser blaster has been fired more than 260,000 times since Curiosity landed inside the nearly 100 mile wide Gale Crater on Mars on Aug. 6, 2012, alongside Mount Sharp.
“ChemCam acts like eyes and ears of the rover for nearby objects,” said Wiens.
“Marias Pass” is a geological context zone where two rock types overlap – pale mudstone meets darker sandstone.
The rover spotted a very curious outcrop named “Missoula.”
“We found an outcrop named Missoula where the two rock types came together, but it was quite small and close to the ground. We used the robotic arm to capture a dog’s-eye view with the MAHLI camera, getting our nose right in there,” said Ashwin Vasavada, the mission’s project scientist at NASA’s Jet Propulsion Laboratory in Pasadena, California.
White mineral veins, possibly comprised of calcium sulfate, filled the fractures by depositing the mineral from running groundwater.
“Such clues help scientists understand the possible timing of geological events,” says the team.

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.

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.
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 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.
“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.”

Former astronaut Bob Cabana, center, director of NASA’s Kennedy Space Center in Florida, Kathy Lueders, manager of the agency’s Commercial Crew Program, and former International Space Station Commander Mike Fincke also took part in the announcement.

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.

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.

“The accident was a huge blow to SpaceX,” Musk told the opening session of the International Space Station Research & Development Conference being held in Boston, Mass, during an on-stage conversation with NASA’s International Space Station manager Mike Suffredini.
Dragon was chock full of over two tons of research experiments and much needed supplies and gear for the multinational crews serving aboard.
“There’s still no clear theory that fits with all the data,” Musk said. “We take these missions incredibly seriously.”
The cargo ships function as a railroad to space and the lifeline to keep the station continuously crewed and functioning. Without periodic resupply by visiting vehicles the ISS cannot operate.
The SpaceX Falcon 9 and Dragon were destroyed just over two minutes after a stunning liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in sunny Florida at 10:21 a.m. EDT.
The upper stage of the rocket suddenly exploded due to an as yet unexplained anomaly as the nine first stage Merlin 1D engines kept firing. Moments later it vaporized into a grayish cloud at supersonic speed, raining debris down into the Atlantic Ocean.
Although the second stage appears to be the culprit in the disaster, Musk said that there is still not a coherent cause and explanation of the data and was hard to interpret.
“Whatever happened is clearly not a sort of simple, straightforward thing,” he explained. “In this case, the data does seem to be quite difficult to interpret.”
“So we want to spend as much time as possible just reviewing the data. No clear theory fits all the data.”
The Falcon 9 was transmitting data on over 3,000 channels of flight data streams.

Virtually since the moment of the mishap approximately 139 seconds after the otherwise successful launch, SpaceX engineers have been pouring over the data to try and determine the root cause of the accident.
“Everyone that can engage in the investigation at SpaceX is very, very focused on that,”Musk elaborated. “We want to spend as much time as possible just reviewing the data.”
From the beginning Musk indicated that there was some type of over pressure event in the upper stage liquid oxygen tank and he elaborated a bit at the conference.
“At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data.”
“So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”
SpaceX is conducting an intense and thorough investigation with the active support of various government agencies including the FAA, NASA and the U.S. Air Force.
“The interaction with NASA has been great so far,” Musk said. “The biggest challenge is that there are a lot of inquiries coming in simultaneously, so it’s hard to keep responding to everyone right away.”

The accident investigation is in full swing both at the Cape and SpaceX headquarters in Hawthorne, Ca.
Hans Koenigsmann, SpaceX VP of Mission Assurance, is leading the accident investigation for SpaceX.
“The process for determining the root cause of Sunday’s mishap is complex, and there is no one theory yet that is consistent with the data,” SpaceX spokesman John Taylor told me earlier.
“Our engineering teams are heads down reviewing every available piece of flight data as we work through a thorough fault tree analysis in order to identify root cause.”

The June 28 launch was the 19th overall for the Falcon 9 booster and the first failure in an otherwise hugely successful program by the new space company founded by Musk and headquartered in Hawthorne, CA. Musk’s oft stated goals include radically slashing the cost of access to space to enable much wider participation in the space frontier by entrepreneurs and individuals and foster much greater exploration that will aid human missions to the Red Planet.
SpaceX may have more to say publicly later this week.
“I think we’ll be able to say something more definitive towards the end of the week,” Musk noted.
In the meantime all SpaceX launches are on hold for several months at least.
Fortunately, the string of launch failures with the successful launch the Russian Progress 60 cargo freighter on July 3, five days after the SpaceX CRS-7 failure. Progress 60 docked at the ISS on July 5 with three tons of supplies, to the relief of the station partners worldwide.
