This past weekend technicians completed assembly of NASA’s first Orion crew module at the agency’s Neil Armstrong Operations and Checkout (O & C) Facility at the Kennedy Space Center (KSC) in Florida, signifying a major milestone in the vehicles transition from fabrication to full scale launch operations.
The black Orion crew module (CM) sits stacked atop the white service module (SM) in the O & C high bay photos, shown above and below.
The black area is comprised of the thermal insulating back shell tiles. The back shell and heat shield protect the capsule from the scorching heat of re-entry into the Earth’s atmosphere at excruciating temperatures reaching over 4000 degrees Fahrenheit (2200 C) – detailed in my story here.
Technicians and engineers from prime contractor Lockheed Martin subsequently covered the crew module with protective foil. The CM/SM stack was then lifted and moved for the installation of the Orion-to-stage adapter ring that will mate them to the booster rocket.

At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and hits the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.
The next step in Orion’s multi stage journey to the launch pad follows later this week with transport of the CM/SM stack to another KSC facility named the Payload Hazardous Servicing Facility (PHFS) for fueling, before moving again for the installation of the launch abort system (LAS) in yet another KSC facility.

NASA is simultaneously developing a monster heavy lift rocket known as the Space Launch System or SLS, that will eventually launch Orion on its deep space missions.
The maiden SLS/Orion launch on the Exploration Mission-1 (EM-1) unmanned test flight is now scheduled for no later than November 2018 – read my story here.
SLS will be the world’s most powerful rocket ever built.
The two-orbit, four and a half hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.

The EFT-1 mission will test the systems critical for EM-1 and future human missions to deep space that follow.
The Orion EFT-1 capsule has come a long way over the past two years of assembly.
The bare bones, welded shell structure of the Orion crew cabin arrived at KSC in Florida from NASA’s Michoud facility in New Orleans in June 2012 and was officially unveiled at a KSC welcoming ceremony on 2 July 2012, attended by this author.
“Everyone is very excited to be working on the Orion. We have a lot of work to do. It’s a marathon not a sprint to build and test the vehicle,” said Jules Schneider, Orion Project manager for Lockheed Martin at KSC, during an exclusive 2012 interview with Universe Today inside the Orion clean room at KSC.

Now just 3 weeks and 4 million miles (6 million kilometers) from rendezvous with Mars, NASA’s ground breaking Mars Atmosphere and Volatile Evolution (MAVEN) orbiter is tracking precisely on course for the crucial Mars Orbital Insertion (MOI) engine firing slated for September 21, 2014.
MAVEN will investigate Mars transition from its ancient, water-covered past, to the cold, dry, dusty world that it has become today.
It’s been a picture perfect flight thus far during the ten month interplanetary voyage from Earth to Mars. To date it has traveled 93% of the path to the Red Planet.
As of August 29th, MAVEN was 198 million kilometers (123 million miles) from Earth and 6.6 million kilometers (4.1 million miles) from Mars. Its velocity is 22.22 kilometers per second (49,705 miles per hour) as it moves on a heliocentric arc around the Sun.
“MAVEN continues on a smooth journey to Mars. All spacecraft systems are operating nominally,” reported David Mitchell, MAVEN Project Manager at NASA’s Goddard Space Flight Center, in an update.

In fact, MAVEN’s navigation from Earth to Mars has been so perfect that the team will likely cancel the final Trajectory Correction Maneuver (TCM) that had been planned for September 12.
The team will make a final decision on whether TCM-4 is necessary on Sept. 4.
Previously the team also cancelled TCM-3 that had been planned for July 23 because it was “not warranted.”
“We are tracking right where we want to be,” says Mitchell.
TCM-1 and TCM-2 took place as scheduled in December 2013 and February 2014, Bruce Jakosky, MAVEN’s Principal Investigator told Universe Today.
These thruster firings ensure the craft is aimed on the correct course through interplanetary space.

“Since we are now in a ‘pre-Mars Orbit Insertion (MOI) moratorium’, all instruments are powered off until after we arrive at the Red Planet,” according to Mitchell.
Although MAVEN’s instrument are resting, the team has no time to rest.
They must ensure that all is in readiness for the MOI burn and held a review at the Jet Propulsion Laboratory with the Deep Space Network (DSN) team and confirmed its readiness to support the engine firing on MOI night.
The entire team also conducted a readiness rehearsal, comprising Lockheed Martin operations center in Denver, Colorado, the backup operations center at Goddard Space Flight Center in Greenbelt, Maryland, and the Jet Propulsion Laboratory in Pasadena, California.
“The review was successful; DSN is ready to support us on MOI night,” says Mitchell.
The do or die MOI maneuver is scheduled for approximately 10 p.m. EDT on Sept. 21, 2014 when MAVEN will rendezvous with the Red Planet following a ten month interplanetary voyage from Earth.
The $671 Million MAVEN spacecraft’s goal is to study Mars upper atmosphere to explore how the Red Planet lost most of its atmosphere and water over billions of years.
The MAVEN probe carries nine sensors in three instrument suites to study why and exactly when did Mars undergo the radical climatic transformation.
“I’m really looking forward to getting to Mars and starting our science!” Bruce Jakosky, MAVEN’s Principal Investigator from the University of Colorado at Boulder, told me.
MAVEN aims to discover the history of water and habitability stretching back over billions of years on Mars.
It will measure current rates of atmospheric loss to determine how and when Mars lost its atmosphere and water.

MAVEN thundered to space over nine months ago on Nov. 18, 2013 following a flawless blastoff from Cape Canaveral Air Force Station’s Space Launch Complex 41 atop a powerful Atlas V rocket and thus began a 10 month interplanetary voyage from Earth to the Red Planet.
MAVEN is streaking to Mars along with ISRO’sMOM orbiter, which arrives a few days later on September 24, 2014.
MOM and MAVEN will join Earth’s fleet of 3 current orbiters from NASA and ESA as well as NASA’s pair of sister surface rovers Curiosity and Opportunity.
Meanwhile last week, NASA announced it was proceeding with development of the mammoth SLS heavy lift rocket that will one day launch astronauts to Mars in the Orion capsule.

Fabrication of the pathfinding version of NASA’s Orion crew capsule slated for its inaugural unmanned test flight in December is entering its final stages at the Kennedy Space Center (KSC) launch site in Florida.
Engineers and technicians have completed the installation of Orion’s back shell panels which will protect the spacecraft and future astronauts from the searing heat of reentry and scorching temperatures exceeding 3,150 degrees Fahrenheit.
Orion is scheduled to launch on its maiden uncrewed mission dubbed Exploration Flight Test-1 (EFT-1) test flight in December 2014 atop the mammoth, triple barreled United Launch Alliance (ULA) Delta IV Heavy rocket from Cape Canaveral, Florida.

The cone-shaped back shell actually has a rather familiar look since its comprised of 970 black thermal protection tiles – the same tiles which protected the belly of the space shuttles during three decades and 135 missions of returning from space.
However, Orion’s back shell tiles will experience temperatures far in excess of those from the shuttle era. Whereas the space shuttles traveled at 17,000 miles per hour, Orion will hit the Earth’s atmosphere at some 20,000 miles per hour on this first flight test.
The faster a spacecraft travels through Earth’s atmosphere, the more heat it generates. So even though the hottest the space shuttle tiles got was about 2,300 degrees Fahrenheit, the Orion back shell could get up to 3,150 degrees, despite being in a cooler area of the vehicle.
Engineers have also rigged Orion to conduct a special in flight test to see just how vulnerable the vehicle is to the onslaught of micrometeoroid orbital debris.
Two one-inch-wide holes have been drilled into tiles on Orion’s back shell to simulate micrometeoroid orbital debris damage.

Even tiny particles can cause immense and potentially fatal damage at high speed by punching a hole through the back shell tiles and possibly exposing the spacecrafts structure to temperatures high than normal.
“Below the tiles, the vehicle’s structure doesn’t often get hotter than about 300 degrees Fahrenheit, but if debris breeched the tile, the heat surrounding the vehicle during reentry could creep into the hole it created, possibly damaging the vehicle,” says NASA.
The team has run done numerous modeling studies on the effect of micrometeoroid hits. Now it’s time for a real world test.
Therefore engineers have purposely drilled a pair of skinny 1 inch wide holes into two 1.47 inches thick tiles to mimic damage from a micrometeoroid hit. The holes are 1.4 inches and 1 inch deep and are located on the opposite side of the back shell from Orion’s windows and reaction control system jets, according to NASA.
“We want to know how much of the hot gas gets into the bottom of those cavities,” said Joseph Olejniczak, manager of Orion aerosciences, in a NASA statement.
“We have models that estimate how hot it will get to make sure it’s safe to fly, but with the data we’ll gather from these tiles actually coming back through Earth’s atmosphere, we’ll make new models with higher accuracy.”

The data gathered will help inform the team about the heat effects from potential damage and possible astronaut repair options in space.
Orion is NASA’s next generation human rated vehicle now under development to replace the now retired space shuttle.
The state-of-the-art spacecraft will carry America’s astronauts on voyages venturing farther into deep space than ever before – past the Moon to Asteroids, Mars and Beyond!
The two-orbit, four and a half hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.
The EFT-1 mission will test the systems critical for future human missions to deep space.

One of the primary goals of NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight is to test the efficacy of the heat shield and back shell tiles in protecting the vehicle – and future human astronauts – from excruciating temperatures reaching over 4000 degrees Fahrenheit (2200 C) during scorching re-entry heating.
At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.
A trio of parachutes will then unfurl to slow Orion down for a splashdown in the Pacific Ocean.
The Orion EFT-1 vehicle is due to roll out of the O & C in about two weeks and be moved to its fueling facility at KSC for the next step in launch processing.
Orion will eventually launch atop the SLS, NASA’s new mammoth heavy lift booster which the agency is now targeting for its maiden launch no later than November 2018 – detailed in my story here.

In the ‘new race to space’ to restore our capability to launch Americans to orbit from American soil with an American-built commercial ‘space taxi’ as rapidly and efficiently as possible, Boeing has moved to the front of the pack with their CST-100 spaceship by completing all their assigned NASA milestones on time and on budget in the current phase of the agency’s Commercial Crew Program (CCP).
Boeing is the first, and thus far only one of the three competitors (including Sierra Nevada Corp. and SpaceX) to complete all their assigned milestone task requirements under NASA’s Commercial Crew Integrated Capability (CCiCap) initiative funded under the auspices of the agency’s Commercial Crew Program.
The CST-100 is a privately built, man rated capsule being developed with funding from NASA via the commercial crew initiative in a public/private partnership between NASA and private industry.
The overriding goal is restart America’s capability to reliably launch our astronauts from US territory to low-Earth orbit (LEO) and the International Space Station (ISS) by 2017.

Private space taxis are the fastest and cheapest way to accomplish that and end the gap in indigenous US human spaceflight launches.
Since the forced shutdown of NASA’s Space Shuttle program following its final flight in 2011, US astronauts have been 100% dependent on the Russians and their cramped but effective Soyuz capsule for rides to the station and back – at a cost exceeding $70 million per seat.
Boeing announced that NASA approved the completion of the final two commercial crew milestones contracted to Boeing for the CST-100 development.
These last two milestones are the Phase Two Spacecraft Safety Review of its Crew Space Transportation (CST)-100 spacecraft and the Critical Design Review (CDR) of its integrated systems.
The CDR milestone was completed in July and comprised 44 individual CDRs including propulsion, software, avionics, landing, power and docking systems.
The Phase Two Spacecraft Safety Review included an overall hazard analysis of the spacecraft, identifying life-threatening situations and ensuring that the current design mitigated any safety risks, according to Boeing.
“The challenge of a CDR is to ensure all the pieces and sub-systems are working together,” said John Mulholland, Boeing Commercial Crew program manager, in a statement.
“Integration of these systems is key. Now we look forward to bringing the CST-100 to life.”

Passing the CDR and completing all the NASA milestone requirements is a significant step leading to the final integrated design for the CST-100 space taxi, ground systems and Atlas V launcher that will boost it to Earth orbit from Space Launch Complex-41 on Cape Canaveral Air Force Station in Florida.
All three American aerospace firms vying for the multibillion dollar NASA contract to build an American ‘space taxi’ to ferry US astronauts to the International Space Station and back as soon as 2017.
NASA’s Commercial Crew Program office is expected to announce the winner(s) of the high stakes, multibillion dollar contract to build America’s next crew vehicles in the next program phase, known as Commercial Crew Transportation Capability (CCtCap), “sometime around the end of August/September,” NASA News spokesman Allard Beutel confirmed to me.
“We don’t have a scheduled date for the commercial crew award(s).”
There will be 1 or more CCtCAP winners.

On June 9, 2014, Boeing revealed the design of their CST-100 astronaut spaceliner by unveiling a full scale mockup of their commercial ‘space taxi’ at the new home of its future manufacturing site at the Kennedy Space Center (KSC) located inside a refurbished facility that most recently was used to prepare NASA’s space shuttle orbiters for assembly missions to the ISS.
The CST-100 crew transporter was unveiled at the invitation only ceremony and media event held inside the gleaming white and completely renovated NASA processing hangar known as Orbiter Processing Facility-3 (OPF-3) – and attended by Universe Today.
The huge 64,000 square foot facility has sat dormant since the shuttles were retired following their final flight (STS-135) in July 2011 and which was commanded by Chris Ferguson, who now serves as director of Boeing’s Crew and Mission Operations.
Ferguson and the Boeing team are determined to get Americans back into space from American soil with American rockets.
Read my exclusive, in depth one-on-one interviews with Chris Ferguson – America’s last shuttle commander – about the CST-100; here and here.

Boeing’s philosophy is to make the CST-100 a commercial endeavor, as simple and cost effective as possible in order to quickly kick start US human spaceflight efforts. It’s based on proven technologies drawing on Boeing’s 100 year heritage in aviation and space.
“The CST-100, it’s a simple ride up to and back from space,” Ferguson told me. “So it doesn’t need to be luxurious. It’s an ascent and reentry vehicle – and that’s all!”
So the CST-100 is basically a taxi up and a taxi down from LEO. NASA’s complementary human space flight program involving the Orion crew vehicle is designed for deep space exploration.
The vehicle includes five recliner seats, a hatch and windows, the pilots control console with several attached Samsung tablets for crew interfaces with wireless internet, a docking port to the ISS and ample space for 220 kilograms of cargo storage of an array of equipment, gear and science experiments depending on NASA’s allotment choices.
The interior features Boeing’s LED Sky Lighting with an adjustable blue hue based on its 787 Dreamliner airplanes to enhance the ambience for the crew.

The reusable capsule will launch atop a man rated United Launch Alliance (ULA) Atlas V rocket.
“The first unmanned orbital test flight is planned in January 2017… and may go to the station,” Ferguson told me during our exclusive interview about Boeing’s CST-100 plans.
Since 2010, NASA has spent over $1.5 billion on the commercial crew effort.
Boeing has received the largest share of funding in the current CCiCAP phase amounting to about $480 million. SpaceX received $460 million for the Dragon V2 and Sierra Nevada Corp. (SNC) has received a half award of $227.5 million for the Dream Chasermini-shuttle.
SNC will be the next company to complete all of NASA’s milestones this Fall, SNC VP Mark Sirangelo told me in an exclusive interview. SpaceX will be the final company finishing its milestones sometime in 2015.

NASA’s first spacecraft dedicated to studying Earth’s atmospheric climate changing carbon dioxide (CO2) levels and its carbon cycle has reached its final observing orbit and taken its first science measurements as the leader of the world’s first constellation of Earth science satellites known as the International “A-Train.”
The ‘first light’ measurements were conducted on Aug. 6 as the observatory flew over central Papua New Guinea and confirmed the health of the science instrument. See graphic below.

Before the measurements could begin, mission controllers had to cool the observatory’s three-spectrometer instrument to its operating temperatures.
“The spectrometer’s optical components must be cooled to near 21 degrees Fahrenheit (minus 6 degrees Celsius) to bring them into focus and limit the amount of heat they radiate. The instrument’s detectors must be even cooler, near minus 243 degrees Fahrenheit (minus 153 degrees Celsius), to maximize their sensitivity,” according to a NASA statement.
The team still has to complete a significant amount of calibration work before the observatory is declared fully operational.
OCO-2 was launched just over a month ago during a spectacular nighttime blastoff on July 2, 2014, from Vandenberg Air Force Base, California, atop a the venerable United Launch Alliance Delta II rocket.
OCO-2 arrived at its final 438-mile (705-kilometer) altitude, near-polar orbit on Aug. 3 at the head of the international A-Train following a series of propulsive burns during July. Engineers also performed a thorough checkout of all of OCO-2’s systems to ensure they were functioning properly.
“The initial data from OCO-2 appear exactly as expected — the spectral lines are well resolved, sharp and deep,” said OCO-2 chief architect and calibration lead Randy Pollock of JPL, in a statement.
“We still have a lot of work to do to go from having a working instrument to having a well-calibrated and scientifically useful instrument, but this was an important milestone on this journey.”

OCO-2 now leads the A-Train constellation, comprising five other international Earth orbiting monitoring satellites that constitute the world’s first formation-flying “super observatory” that collects an unprecedented quantity of nearly simultaneous climate and weather measurements.
Scientists will use the huge quantities of data to record the health of Earth’s atmosphere and surface environment as never before possible.
OCO-2 is followed in orbit by the Japanese GCOM-W1 satellite, and then by NASA’s Aqua, CALIPSO, CloudSat and Aura spacecraft, respectively. All six satellites fly over the same point on Earth within 16 minutes of each other. OCO-2 currently crosses the equator at 1:36 p.m. local time.

The 999 pound (454 kilogram) observatory is the size of a phone booth.
OCO-2 is equipped with a single science instrument consisting of three high-resolution, near-infrared spectrometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change and is responsible for Earth’s warming.
During a minimum two-year mission the $467.7 million OCO-2 will take near global measurements to locate the sources and storage places, or ‘sinks’, for atmospheric carbon dioxide, which is a critical component of the planet’s carbon cycle.
OCO-2 was built by Orbital Sciences as a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly and the spacecraft plunged into the ocean.
The OCO-2 mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA.
Here’s a NASA description of how OCO-2 collects measurements.
As OCO-2 flies over Earth’s sunlit hemisphere, each spectrometer collects a “frame” three times each second, for a total of about 9,000 frames from each orbit. Each frame is divided into eight spectra, or chemical signatures, that record the amount of molecular oxygen or carbon dioxide over adjacent ground footprints. Each footprint is about 1.3 miles (2.25 kilometers) long and a few hundred yards (meters) wide. When displayed as an image, the eight spectra appear like bar codes — bright bands of light broken by sharp dark lines. The dark lines indicate absorption by molecular oxygen or carbon dioxide.
It will record around 100,000 precise individual CO2 measurements around the worlds entire sunlit hemisphere every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.

At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million, which is the most in at least 800,000 years, says NASA.
OCO-2 is the second of NASA’s five new Earth science missions planned to launch in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

The orbital airframe structure for the first commercial Dream Chaser mini-shuttle that will launch to Earth orbit just over two years from now has been unveiled by Sierra Nevada Corporation (SNC) and program partner Lockheed Martin.
Sierra Nevada is moving forward with plans for Dream Chaser’s first launch and unmanned orbital test flight in November 2016 atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral, Florida.

Lockheed Martin is fabricating the structural components for the Dream Chaser’s orbital spacecraft composite structure at the NASA’s Michoud Assembly Facility (MAF) in New Orleans, Louisiana.
MAF has played a long and illustrious history in human space flight dating back to Apollo and also as the site where all the External Tanks for NASA’s space shuttle program were manufactured. Lockheed Martin also builds the pressure vessels for NASA’s deep space Orioncrew vehicle at MAF.
Each piece is thoroughly inspected to insure it meets specification and then shipped to Lockheed Martin’s Aeronautics facility in Fort Worth, Texas for integration into the airframe and co-bonded assembly.

Sierra Nevada chose Lockheed Martin for this significant role in building Dream Chaser airframe based on their wealth of aerospace experience and expertise.
The composite airframe structure was recently unveiled at a joint press conference by Sierra Nevada Corporation and Lockheed Martin at the Fort Worth facility.
“As a valued strategic partner on SNC’s Dream Chaser Dream Team, Lockheed Martin is under contract to manufacture Dream Chaser orbital structure airframes,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems, in a statement.
“We competitively chose Lockheed Martin because they are a world leader in composite manufacturing, have the infrastructure, resources and quality control needed to support the needs of an orbital vehicle and have a proven track record of leading our nation’s top aviation and aerospace programs. Lockheed Martin’s diverse heritage coupled with their current work on the Orion program adds an extra element of depth and expertise to our program. SNC and Lockheed Martin continue to expand and develop a strong multi-faceted relationship.”
Dream Chaser measures about 29 feet long with a 23 foot wide wing span and is about one third the size of NASA’s space shuttle orbiters.
“We are able to tailor our best manufacturing processes, and our innovative technology from across the corporation to fit the needs of the Dream Chaser program,” said Jim Crocker, vice president of Lockheed Martin’s Space Systems Company Civil Space Line of Business.
Upon completion of the airframe manufacturing at Ft Worth, it will be transported to SNC’s Louisville, Colorado, facility for final integration and assembly.
SNC announced in July that they successfully completed and passed a series of risk reduction milestone tests on key flight hardware systems under its Commercial Crew Integrated Capability (CCiCap) agreement with NASA that move the private reusable spacecraft closer to its critical design review (CDR) and first flight.
As a result of completing Milestones 9 and 9a, SNC has now received 92% of its total CCiCAP Phase 1 NASA award of $227.5 million.
“We are on schedule to launch our first orbital flight in November of 2016, which will mark the beginning of the restoration of U.S. crew capability to low-Earth orbit,” says Sirangelo.
The private Dream Chaser is a reusable lifting-body design spaceship that will carry a mix of cargo and up to a seven crewmembers to the ISS. It will also be able to land on commercial runways anywhere in the world, according to SNC.
Dream Chaser is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the International Space Station by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.
The SpaceX Dragon and Boeing CST-100 ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around September 2014, NASA officials have told me.

The tests are among the milestones SNC must complete to receive continued funding from the Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.
Over 3,500 tests were involved in completing the Risk Reduction and TRL advancement tests on the seven hardware systems whose purpose is to significantly retire overall program risk enable a continued maturation of the Dream Chaser’s design.
Dream Chaser is a reusable lifting-body design spaceship that will carry a mix of cargo and up to a seven crewmembers to the ISS. It will also be able to land on commercial runways anywhere in the world, according to SNC.
“By thoroughly assessing and mitigating each of the previously identified design risks, SNC is continuing to prove that Dream Chaser is a safe, robust, and reliable spacecraft,” said Mark N. Sirangelo, corporate vice president of SNC’s Space Systems, in a statement.
“These crucial validations are vital steps in our Critical Design Review and in showing that we have a very advanced and capable spacecraft. This will allow us to quickly and confidently move forward in restoring cutting-edge transportation to low-Earth orbit from the U.S.”

The SpaceXDragon and BoeingCST-100 ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around August/September 2014.
“Our partners are making great progress as they refine their systems for safe, reliable and cost-effective spaceflight,” said Kathy Lueders, manager of NASA’s Commercial Crew Program.
“It is extremely impressive to hear and see the interchange between the company and NASA engineering teams as they delve into the very details of the systems that help assure the safety of passengers.”
After completing milestones 9 and 9a, SNC has now received 92% of its total CCiCAP Phase 1 NASA award of $227.5 million.
“We are on schedule to launch our first orbital flight in November of 2016, which will mark the beginning of the restoration of U.S. crew capability to low-Earth orbit,” says Sirangelo.
Dream Chaser measures about 29 feet long with a 23 foot wide wing span and is about one third the size of NASA’s space shuttle orbiters.
It will launch atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Launch Complex 41 in Florida.
Since the forced shutdown of NASA’s Space Shuttle program following its final flight in 2011, US astronauts have been 100% dependent on the Russians and their cramped but effective Soyuz capsule for rides to the station and back – at a cost exceeding $70 million per seat.
The Dream Chaser design builds on the experience gained from NASA Langley’s earlier exploratory engineering work with the HL-20 manned lifting-body vehicle.

Following a nearly three-year long hiatus, the workhorse Delta II rocket successfully launched NASA’s first spacecraft dedicated to watching Earth breathe by studying Earth’s atmospheric carbon dioxide (CO2) – the leading human-produced greenhouse gas and the principal human-produced driver of climate change.
The Orbiting Carbon Observatory-2 (OCO-2) raced to orbit earlier this morning, during a spectacular nighttime blastoff at 2:56 a.m. PDT (5:56 a.m. EDT), Tuesday, July 2, 2014, from Vandenberg Air Force Base, California, atop a United Launch Alliance Delta II rocket.
The flawless launch marked the ‘return to flight’ of the venerable Delta II and was broadcast live on NASA TV.

A camera mounted on the Delta II’s second stage captured a breathtaking live view of the OCO-2 spacecraft during separation from the upper stage, which propelled it into an initial 429-mile (690-kilometer) orbit.
The life giving solar arrays were unfurled soon thereafter and NASA reports that the observatory is in excellent health.
“Climate change is the challenge of our generation,” said NASA Administrator Charles Bolden in a statement.
“With OCO-2 and our existing fleet of satellites, NASA is uniquely qualified to take on the challenge of documenting and understanding these changes, predicting the ramifications, and sharing information about these changes for the benefit of society.”

Over the next three weeks the OCO-2 probe will undergo a thorough checkout and calibration process. It will also be maneuvered into a 438-mile (705-kilometer) altitude, near-polar orbit where it will become the lead science probe at the head of the international Afternoon Constellation, or “A-Train,” of Earth-observing satellites.
“The A-Train, the first multi-satellite, formation flying “super observatory” to record the health of Earth’s atmosphere and surface environment, collects an unprecedented quantity of nearly simultaneous climate and weather measurements,” says NASA.
Science operations begin in about 45 days.
The 999 pound (454 kilogram) observatory is the size of a phone booth.
OCO-2 is equipped with a single science instrument consisting of three high-resolution, near-infrared spec¬trometers fed by a common telescope. It will collect global measurements of atmospheric CO2 to provide scientists with a better idea of how CO2 impacts climate change and is responsible for Earth’s warming.

During a minimum two-year mission the $467.7 million OCO-2 will take near global measurements to locate the sources and storage places, or ‘sinks’, for atmospheric carbon dioxide, which is a critical component of the planet’s carbon cycle.
OCO-2 was built by Orbital Sciences as a replacement for the original OCO which was destroyed during the failed launch of a Taurus XL rocket from Vandenberg back in February 2009 when the payload fairing failed to open properly and the spacecraft plunged into the ocean.
The OCO-2 mission will provide a global picture of the human and natural sources of carbon dioxide, as well as their “sinks,” the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored, according to NASA.
“This challenging mission is both timely and important,” said Michael Freilich, director of the Earth Science Division of NASA’s Science Mission Directorate in Washington.
“OCO-2 will produce exquisitely precise measurements of atmospheric carbon dioxide concentrations near Earth’s surface, laying the foundation for informed policy decisions on how to adapt to and reduce future climate change.”
It will record around 100,000 precise individual CO2 measurements around the worlds entire sunlit hemisphere every day and help determine its source and fate in an effort to understand how human activities impact climate change and how we can mitigate its effects.
At the dawn of the Industrial Revolution, there were about 280 parts per million (ppm) of carbon dioxide in Earth’s atmosphere. As of today the CO2 level has risen to about 400 parts per million.
“Scientists currently don’t know exactly where and how Earth’s oceans and plants have absorbed more than half the carbon dioxide that human activities have emitted into our atmosphere since the beginning of the industrial era,” said David Crisp, OCO-2 science team leader at NASA’s Jet Propulsion Laboratory in Pasadena, California, in a statement.
“Because of this, we cannot predict precisely how these processes will operate in the future as climate changes. For society to better manage carbon dioxide levels in our atmosphere, we need to be able to measure the natural source and sink processes.”
OCO-2 is the second of NASA’s five new Earth science missions planned to launch in 2014 and is designed to operate for at least two years during its primary mission. It follows the successful blastoff of the joint NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory satellite on Feb 27.

The two stage Delta II 7320-10 launch vehicle is 8 ft in diameter and approximately 128 ft tall and was equipped with a trio of first stage strap on solid rocket motors. This marked the 152nd Delta II launch overall and the 51st for NASA since 1989.
The last time a Delta II rocket flew was nearly three years ago in October 2011 from Vandenberg for the Suomi National Polar-Orbiting Partnership (NPP) weather satellite.
The next Delta II launch later this year from Vandenberg involves NASA’s Soil Moisture Active Passive (SMAP) mission and counts as another of NASA’s five Earth science missions launching in 2014.

A test version of NASA’s Orion deep space capsule has completed its most complex and last full flight-like parachute drop test on June 25 ahead of the maiden launch on the EFT-1 mission now slated for early December 2014.
The descent test was conducted at an altitude of 35,000 feet over the Arizona desert at the U.S. Army’s Yuma Proving Ground by pulling the test vehicle out of a huge C-17 cargo aircraft.
The test also included the addition of several added stress tests to check out the ability of the parachute system to compensate and examine capsule and astronaut crew survival via several potential failure modes.
For example, engineers rigged one of the main parachutes to skip the intermediate phase of the three-phase process to unfurl each of Orion’s three parachutes, called reefing.
“This tested whether one of the main parachutes could go directly from opening a little to being fully open without an intermediary step, proving the system can tolerate potential failures,” according to NASA.
The goal is to prove that that parachute system will slow Orion to ensure a safe landing speed for the astronaut crews returning from deep space missions to the Moon, Asteroids and eventually Mars.

“We’ve put the parachutes through their paces in ground and airdrop testing in just about every conceivable way before we begin sending them into space on Exploration Flight Test (EFT)-1 before the year’s done,” said Orion Program Manager Mark Geyer in a state
“The series of tests has proven the system and will help ensure crew and mission safety for our astronauts in the future.”
Orion is slated to launch on its inaugural unmanned EFT-1 test flight in December 2014 atop the mammoth, triple barreled United Launch Alliance (ULA) Delta IV Heavy rocket from Cape Canaveral, Florida.

This test also marked the last time that the entire parachute sequence involving the deployment of all three 116 foot-wide main chutes will be tested before the December launch.
For some of the parachutes, this was the highest altitude drop test attempted.
“Engineers also put additional stresses on the parachutes by allowing the test version of Orion to free fall for 10 seconds, which increased the vehicle’s speed and aerodynamic pressure,” NASA noted in a statement.
The parachute deployment and unfurling can only begin after jettisoning of the spacecraft’s forward bay cover. The chutes are housed below the cover which protects the chutes until reentry into Earth’s atmosphere.
The two-orbit, four- hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years.
One of the primary goals of NASA’s eagerly anticipated Orion EFT-1 uncrewed test flight is to test the efficacy of the heat shield in protecting the vehicle – and future human astronauts – from excruciating temperatures reaching 4000 degrees Fahrenheit (2200 C) during scorching re-entry heating.
At the conclusion of the EFT-1 flight, the detached Orion capsule plunges back and re-enters the Earth’s atmosphere at 20,000 MPH (32,000 kilometers per hour).
“That’s about 80% of the reentry speed experienced by the Apollo capsule after returning from the Apollo moon landing missions,” Scott Wilson, NASA’s Orion Manager of Production Operations at KSC, told me during an interview at KSC.
The parachute system comprising of two drogue parachutes and a trio of main parachutes – nearly the size of a football field – will then unfurl to slow Orion down to just 20 mph for a safe splashdown and recovery by the US Navy in the Pacific Ocean.

Another drop test scheduled for August will test the combined failure of one drogue parachute and one main parachute, as well as new parachute design features, says NASA.
Meanwhile, Orion’s prime contractor Lockheed Martin is finishing assembly and test operations of the EFT-1 capsule inside the Operations and Checkout Facility (O & C) at the Kennedy Space Center (KSC) flying in December’s launch
