She’s gonna blow! Rosetta’s navigation camera recently grabbed our best view yet of the geyser-like jets spraying from the nucleus of Comet 67P/Churyumov-Gerasimenko. They were taken on September 26 as the spacecraft orbited the comet at a distance of just 16 miles (26 km) and show jets of water vapor and dust erupting from several discrete locations beneath the surface along the neck region of the comet’s nucleus. Mattias Malmer, a 3D technical director, created the spectacular 3D views by draping the navigation camera images over a 3D model of the comet and then photographing it from two slightly different perspectives.

Jets form when the sun warms the comet’s coal-black surface, causing ices beneath to sublimate or change directly from solid to gas without becoming liquid. This is possible because of the near-zero atmospheric pressure at the comet. Pressure builds in the pockets of gas until they find escape through cracks or pores as plume-like jets. Comet dust along with the gas fashions the coma and tail over time. Something similar happens when you shake up a bottle of champagne and then loosen the cork. Trapped carbon dioxide (what makes the “fizz”) blasts the cork across the room.

ISRO and NASA have inked a deal to collaborate on future missions to jointly explore the Red Planet and our Home Planet hot on the heels of ISRO’s wildly successful Mars Orbiter Mission (MOM), India’s first ever interplanetary voyager to explore Mars.
NASA Administrator Charles Bolden and K. Radhakrishnan, chairman of the Indian Space Research Organisation (ISRO), signed an agreement to collaborate on future science missions to explore Mars as well as to build and launch a joint NASA-ISRO mission to observe Earth.
The leaders of NASA and ISRO met in Toronto, Canada on Tuesday, Sept. 30 and “signed two documents to launch a NASA-ISRO satellite mission to observe Earth and establish a pathway for future joint missions to explore Mars,” according to a NASA statement.
Bolden and Rao met at the International Astronautical Congress underway in Toronto.

They signed one agreement defining each agency’s responsibilities for the joint NASA-ISRO Synthetic Aperture Radar (NISAR) mission, targeted to launch in 2020. NISAR will make global measurements of the causes and consequences of land surface changes.
The second agreement “establishes a NASA-ISRO Mars Working Group to investigate enhanced cooperation between the two countries in Mars exploration.”
“The signing of these two documents reflects the strong commitment NASA and ISRO have to advancing science and improving life on Earth,” said NASA Administrator Charles Bolden, in a NASA statement.
“This partnership will yield tangible benefits to both our countries and the world.”
NISAR will be the first Earth observing mission to be equipped two different synthetic aperture radar (SAR) frequencies (L-band and S-band) – one each from NASA and ISRO.
NASA will also provide “the high-rate communication subsystem for science data, GPS receivers, a solid state recorder, and a payload data subsystem.”
ISRO will provide the spacecraft bus and launch vehicle.
The radars will be able to measure subtle changes in Earth’s surface of less than a centimeter across stemming from the flow of glaciers and ice sheets as well as earthquakes and volcanoes.
Regarding Mars, the first subject the joint working group will tackle will be to coordinate observations from each nation’s recently arrived Mars orbiters – ISRO’s MOM and NASA’s MAVEN. They will also examine areas of future collaboration on surface rovers and orbiters.
“NASA and Indian scientists have a long history of collaboration in space science,” said John Grunsfeld, NASA Associate Administrator for Science.
“These new agreements between NASA and ISRO in Earth science and Mars exploration will significantly strengthen our ties and the science that we will be able to produce as a result.”

The march towards first launch of NASA’s next generation Orion crew vehicle is accelerating rapidly.
The world’s most powerful rocket – the United Launch Alliance Delta IV Heavy – was moved to its Cape Canaveral launch pad overnight and raised at the pad today, Oct. 1, thereby setting in motion the final steps to prepare for blastoff of NASA’s new Orion capsule on its first test flight in just over two months.
All the pieces are ready and now it’s just a matter of attaching all those components together for the inaugural uncrewed liftoff of the state-of-the-art Orion spacecraft on its maiden mission dubbed Exploration Flight Test-1 (EFT-1) in December.
“We’ve been working toward this launch for months, and we’re in the final stretch,” said Kennedy Director Bob Cabana, in a NASA statement.
“Orion is almost complete and the rocket that will send it into space is on the launch pad. We’re 64 days away from taking the next step in deep space exploration.”
The triple barreled Delta IV Heavy topped by the Orion EFT-1 capsule is slated to blastoff on December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.

After a nearly two day delay due to drenching rain storms, the Delta IV Heavy integrated first and second stages were transported horizontally overnight Wednesday starting around 10 p.m. from the processing hanger inside ULA’s Horizontal Integration Facility (HIF) to the nearby launch complex and servicing gantry at Pad 37.
Early this morning, the rocket was hoisted up into its launch configuration. Several of my space photo-journalist colleagues were on hand. See their photos herein.
From now until launch technicians will conduct the final processing, testing and checkout of the Delta IV Heavy booster. They will also carry out “a high fidelity rehearsal to include fully powering up the booster and loading the tanks with fuel and oxidizer,” according to ULA.
“This is a tremendous milestone and gets us one step closer to our launch later this year,” said Tony Taliancich, ULA’s director of East Coast Launch Operations, in a ULA statement.
“The team has worked extremely hard to ensure this vehicle is processed with the utmost attention to detail and focus on mission success.”
“The Delta IV Heavy is the world’s most powerful launch vehicle flying today, and we are excited to be supporting our customer for this critical flight test to collect data and reduce overall mission risks and costs for the program,” said Taliancich.

NASA’s Orion Program manager Mark Geyer told me in a recent interview that the Orion spacecraft, built by prime contractor Lockheed Martin, will be transported to the pad around November 10 or 11. Then the Orion will be hoisted and attached to the top of the Delta IV Heavy rocket at the base of its service module.
The Delta IV Heavy first stage is comprised of a trio of three Common Booster Cores (CBCs).

Each CBC measures 134 feet in length and 17 feet in diameter. They are equipped with an RS-68 engine powered by liquid hydrogen and liquid oxygen propellants producing 656,000 pounds of thrust. Together they generate 1.96 million pounds of thrust.
The Delta IV Heavy became the world’s most powerful rocket upon the retirement of NASA’s Space Shuttle program and is the only vehicle that is sufficiently powerful to launch the Orion EFT-1 spacecraft.
The first CBC booster was attached to the center booster in June. The second one was attached in early August.

I recently visited the HIF during a media tour after the three CBCs had been joined together as well as earlier this year after the first two CBCs arrived by barge from their ULA assembly plant in Decatur, Alabama, located about 20 miles west of Huntsville. See my photos herein.
I was also on hand at KSC when the Orion crew module/service module (CM/SM) stack was rolled out on Sept. 11, 2014, on a 36 wheeled transporter from its high bay assembly facility in the Neil Armstrong Operations and Checkout Building.
It was moved about 1 mile to the KSC fueling facility named the Payload Hazardous Servicing Facility (PHFS). Read my Orion move story – here.
Fueling of Orion was completed over the weekend and it has now been moved to the Launch Abort System Facility (LASF) for the installation of its last component – the Launch Abort System (LAS).
Orion’s next stop is SLC-37.
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.
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 and the assembly of its core stage has begun at NASA’s Michoud Assembly Facility in New Orleans. Read my story – here.

Phobos. From where did it arise or arrive? Is it dry or wet? Should we flyby or sample and return? Should it be Boots or Bots? (Photos: NASA, Illus.:T.Reyes)
Ask any space enthusiast, and almost anyone will say humankind’s ultimate destination is Mars. But NASA is currently gearing up to go to an asteroid. While the space agency says its Asteroid Initiative will help in the eventual goal of putting people on Mars, what if instead of going to an asteroid, we went to Mars’ moon Phobos?
Three prominent planetary scientists have joined forces in a new paper in the journal Planetary and Space Science to explain the case for a mission to the moons of Mars, particularly Phobos.
“Phobos occupies a unique position physically, scientifically, and programmatically on the road to exploration of the solar system,” say the scientists. In addition, the moons may possibly be a source of in situ resources that could support future human exploration in circum-Mars space or on the Martian surface. But a sample return mission first could provide details on the moons’ origins and makeup.
The Martian moons are riddles, wrapped in a mystery, inside an enigma.Phobos and its sibling Deimos seem like just two asteroids which were captured by the planet Mars, and they remain the last objects of the inner solar system not yet studied with a dedicated mission. But should the moons be explored with flybys or sample-return? Should we consider “boots or bots”?
The publications and mission concepts for Phobos and Deimos are numerous and go back decades. The authors of “The Value of a Phobos Sample Return,” Murchie, Britt, and Pieters, explore the full breadth of questions of why and how to explore Phobos and Deimos.
Dr. Murchie is the principal investigator of the Mars Reconnaissance Orbiter’s CRISM instrument, a visible/infrared imaging spectrometer. He is a planetary scientist from John Hopkins’ Applied Physics Lab (APL) which has been at the forefront of efforts to develop a Phobos mission. Likewise, authors Dr. Britt, from the University of Central Florida, and Dr. Pieters, from Brown University, have partnered with APL and JPL in Phobos/Deimos mission proposals.

APL scientists are not the only ones interested in Phobos or Deimos. The Jet Propulsion Laboratory, Ames Research Center and the SETI Institute have also proposed several missions to the small moons. Every NASA center has been involved at some level.
But the only mission to actually get off the ground is the Russian Space Agency’s Phobos-GRUNT[ref]. The Russian mission was launched November 9, 2011, and two months later took a bath in the Pacific Ocean. The propulsion system failed to execute the burns necessary to escape the Earth’s gravity and instead, its orbit decayed despite weeks of attempts to activate the spacecraft. But that’s a whole other story.

“The Value of a Phobos Sample Return” first discusses the origins of the moons of Mars. There is no certainty. There is a strong consensus that Earth’s Moon was born from the collision of a Mars-sized object with Earth not long after Earth’s formation. This is just one possibility for the Martian moons. Murchie explains that the impacts that created the large basins and craters on Mars could have spawned Phobos and Deimos: ejecta that achieved orbit, formed a ring and then coalesced into the small bodies. Alternative theories claim that the moons were captured by Mars from either the inner or outer solar system. Or they could have co-accreted with Mars from the Solar Nebula. Murchie and the co-authors describe the difficulties and implications of each scenario. For example, if captured by Mars, then it is difficult to explain how their orbits came to be “near-circular and near-equatorial with synchronous rotational periods.”
To answer the question of origins, the paper turns to the questions of their nature. Murchie explains that the limited compositional knowledge leaves several possibilities for their origins. They seem like D-type asteroids of the outer asteroid belt. However, the moons of Mars are very dry, void of water, at least on their surfaces as the paper discusses in detail. The flybys of Phobos and Deimos by NASA and ESA spacecraft are simply insufficient for drawing any clear picture of their composition or structure, let alone their origins, Murchie and co-authors explain.
If the moons were captured then they have compositions different from Mars; however if they accreted with or from Mars, then they share similar compositions with the early Mars when forming, or from Martian crustal material, respectively.
The paper describes in some detail the problem that billions of years of Martian dust accumulation presents. Every time Mars has been hit by a large asteroid, a cloud of debris is launched into space. Some falls back to the planet but much ends up in orbit. Each time, some of the debris collided with Phobos and Deimos; Murchie uses the term “Witness plate” to describe what the two moons are to Mars. There is an accumulation of Martian material and also material from the impactors covering the surfaces of the moons. Flyby images of Phobos show a reddish surface similar to Mars, and numerous tracks along the surface as if passing objects struck, plowed or rolled along. However, the reddish hue could be weathering from Solar flux over billions of years.
The paper continues with questions of the composition and how rendezvous missions could go further to understanding the moons makeup and origins, however, it is sample return that would deliver, the pay dirt. Despite how well NASA and ESA engineers have worked to shrink and lighten the instruments that fly, orbit, and land on Mars, returning a sample of Phobos to labs on Earth would permit far more detailed analysis.
SpaceX and Elon Musk claim that they will mount human flight to Mars before 2030. Many others remain less optimistic with hopes of human flights before 2040. (Illustrations: Total Recall, 1990, early artist illustration c.1950s )
Science Fiction writers and mission designers have imagined Phobos, in particular, as a starting point for the human exploration and colonization of Mars. A notable contemporary work is “Red Mars” by Kim Stanley Robinson; however, the story line is dated due to the retirement of the Space Shuttle and the external tanks Robinson clustered to form the colonization vessel. While this paper by Murchie et al. is purely scientific, fiction writers have used the understanding that Phobos is far easier to reach from Earth than is the surface of Mars (see Delta-V chart below).
A diagram showing the stair-step energy needed to travel to places beyond the Earth. Delta-V is the speed in km/sec required to reach a destination. As shown, the Delta-Vs are cumulative. Note that it takes an extra 5 km/sec beyond Phobos to reach the Martian surface; a prime reason for making the journey to the moons of Mars. (Credit: Wikipedia, Delta-V)
Phobos, orbiting at 9,400 kilometers (5,840 miles), and Deimos, at 23,500 km (14,600 miles), above Mars avoids the need for the 7-odd minutes of EDL terror – Entry, Descent, and Landing — and pulling oneself out of the Martian gravity well to return to Earth. Furthermore, there is the interest in using Phobos as a material resource – water, material for rocket fuel or building materials. “The Value of a Phobos Sample Return” discusses the potential of Phobos as a resource for space travelers – “In Situ Resource Utilization” (ISRU), in the context of its composition, how the solar flux may have purged the moons of water or how Martian impact debris covers materials of greater interest and value to explorers.
With so many questions and interests, what missions have been proposed and explored? The Murchie paper describes a half dozen missions but there are several others that have been conceived and proposed to some level over several decades.
At present, there is at least one mission actively pursuing funds. The SETI and Ames proposed “Phobos and Deimos & Mars Environment” (PADME) mission led by Dr. Pascal Lee is competing for Discovery program funding. Such projects must limit cost to $425 million or less and be capable of launching in less than 3 years. They are proposing a launch date of 2018 on a SpaceX Falcon 9. The PADME mission design would reuse Ames LADEE hardware and expertise, however, it does not go so far as what Murchie and co-authors argue – returning a sample from Phobos. PADME would maintain in a synchronized orbit with Phobos and then Deimos foe repeated flybys. The mission is likely to cost in the range of $300 million. Stardust, a relevant mission due to its sample return capsule, launched in 1999 and had costs which likely reached a similar level by end of mission in 2012.
The Russian Space Agency is attempting to gain funding for Phobos-Grunt 2 but possible launch dates continue to be moved back – 2020, 2022, and now possibly 2024.

Additionally, each of this papers’ authors has mission proposals described. Dr. Pieters, JPL, and Lockheed-Martin proposed the Aladdin mission; Dr. Britt at APL, also with Lockheed-Martin, proposed the mission Gulliver; both would re-use the Stardust sample-return capsule (photo, above). Dr. Murchie also describes his APL/JPL mission concept called MERLIN (Mars–Moon Exploration, Reconnaissance and Landed Investigation).
Phobos and Deimos are the last two of what one would call major objects of the inner Solar System that have not had dedicated missions of exploration. Several bodies of the Asteroid Belt have been targeted with flybys and Dawn is nearing its second target, the largest of the Asteroids, Ceres.
So sooner rather than later, a spacecraft from some nation (not necessarily the United States) will target the moons of Mars. Targeted Phobos/Deimos missions are also likely to include both flyby missions and one or more sample-return missions. A US-led mission with sample-return in the Discovery program will be strained to meet both criteria – $425 million cost cap and 3 year development period.
Those utilizing the Lockheed-Martin (LM) Stardust design have a proven return capsule and spacecraft buses (structure, mechanisms and avionics) for re-use for cost and time savings. This includes five generations of the LM flight software that holds an incredible legacy of mission successes starting with Mars Odyssey/Genesis/Spitzer to now Maven.
All three proposals by this paper’s authors could be re-vamped and proposed again and compete against each other. All three could use Lockheed-Martin past designs. Cooperation in writing this paper may be an indicator that they will join forces, combine concepts, and share investigator positions on a single NASA-led project. The struggle for federal dollars remains a tough, tight battle and with the human spaceflight program struggling to gain a new footing after Space Shuttle, dollars for inter-planetary missions are likely to remain very competitive. However, it appears a Phobos-Deimos mission is likely within the next ten years.

TORONTO, CANADA – There’s a big difference in thinking between governments and the private companies that participate in space. While entities such as NASA can work on understanding basic human health or exploring the universe for the sake of a greater understanding, companies have a limitation: they need to eventually make a profit.
This was brought up in a human spaceflight discussion at the International Astronautical Congress today (Oct. 1), which included participants from agencies and companies alike. Below are some concepts for how private companies in the space world today are making their money.
“We have in space a movement towards more privatization … and also for more use of space activities in general and human space activity in the future by individual private persons,” said Johann Dietrich Worner, chairman of the executive board of DLR (Germany’s space agency), in the panel.
“You can imagine that even for the upcoming 10 to 20 to 30 years, the public funding is the basic funding for [space] activities while in other areas, we are already seeing that private money is doing its work if you look to communication and if you look to other activities, like for instance, research in space.”
But commercial spaceflight is already taking place, as some of these examples show.
Commercial crew

The two successful companies in NASA’s latest round of commercial contracts — SpaceX (Dragon) and Boeing (CST-100) — are each receiving government money to develop their private space taxis. The companies are responsible for meeting certain milestones to receive funds. There is quite the element of risk involved because the commercial contracts are only given out in stages; you could be partway through developing the spacecraft and then discover you will not be awarded one for the next round. This is what happened to Sierra Nevada Corp., whose Dream Chaser concept did not receive more money in the announcement last month. The company has filed a legal challenge in response.
Private space travel
Sir Richard Branson hugs designer Burt Rutan, surrounded by employees of Virgin Galactic, The SpaceShip Company, and Scaled Composites, and watch as Virgin Galactic’s SpaceShip2 streaks across the sky under rocket power, its first ever since the program began in 2005. Burt’s wife Tonya Rutan is at right taking their photo. The spacecraft was dropped from its “mothership,” WhiteKnight2, over the Mojave CA area on April 29, 2013, at high altitude before firing its hybrid power motor. Virgin Galactic hopes to become the first commercial space venture to bring multiple passengers into space on a regular basis.
Virgin Galactic and its founder, Richard Branson, are perhaps the most visible of the companies that are looking to bring private citizens into space — as long as they can pay $250,000 for a ride. The first flight of Virgin into space is expected in the next year. Customers must pay a deposit upfront upon registering and then the balance before they head into suborbit. In the case of Virgin, Branson has a portfolio of companies that can take on the financial risk during the startup phase, but eventually the company will look to turn a profit through the customer payments.
Asteroid mining

The business case for Planetary Resources and Deep Space Industries, the two self-proclaimed asteroid mining companies, hasn’t fully been released yet. We assume that the companies would look to make a profit through selling whatever resources they manage to dig up on asteroids, but bear in mind it would cost quite a bit of money to get a spacecraft there and back. Meanwhile, Planetary Resources is diversifying its income somewhat by initiatives such as the Arkyd-100 telescope, which will look for asteroids from Earth orbit. They raised money for the project through crowdsourcing.

NanoRacks is a company that has research slots available on the International Space Station that it sells to entities looking to do research in microgravity. The company has places inside the station and can also deploy small satellites through a Japanese system. While the company’s website makes it clear that they are focused on ISS utilization, officials also express an interest in doing research in geocentric orbit, the moon or even Mars.

TORONTO, CANADA – Could NASA’s new rocket bring a probe to sample the geysers of Saturn’s moon Enceladus, or ferry human explorers to the surface of Mars? Representatives of contractor Boeing think so.
They’ve put together some ideas for sending their Space Launch System to these far-flung destinations, which they presented at the International Astronautical Congress today (Oct. 1).
Bear in mind that the SLS hasn’t yet flown — it’s slated for 2018 if funding lasts and the schedule holds — and the destinations below are just in the conceptual stage. The gallery below summarizes some of the destinations SLS could visit. For more information, check out this brochure by Boeing.
Enceladus

The icy moon of Saturn is known as a hotspot for geysers; earlier this year, scientists found 101 gushers using data from the prolific Cassini probe. Using the SLS could bring a satellite there in four years, as opposed to about seven with rockets on the market today, according to Boeing. It also could carry a heavier spacecraft.
Europa

Europa is known to have a subterranean ocean, and it also is capable of spewing water plumes — as researchers using the Hubble Space Telescope discovered earlier this year. The SLS could get to Europa a lot faster than a launch with an Atlas, according to Boeing — it would only take two years to fly there directly as opposed to more than six years with the Atlas, which would need to fly by Venus first to pick up some speed.
Trojan asteroids

Trailing before and after Jupiter are more than a million asteroids that are called Trojans. This means any probe in the area would have no lack of targets to study, providing it had enough fuel on board. A mission profile from Boeing suggests the SLS could bring a spacecraft out there that could swing by a target at least half a dozen times.
Mars

One of the largest challenges of getting to Mars is figuring out how to send all the life-support equipment and food that humans require — on top of the humans themselves! Since SLS is a heavy-lift rocket, Boeing is trying to position its rocket as the ideal one to get humans to Mars. But it remains to be seen what concept works best to get people out there.
The Moon

Boeing has an idea to bring a lander down to the Moon that could then lift off multiple times in search of other destinations. Such a concept would require a hefty amount of fuel and equipment. If it works, Boeing says the SLS could assist with plans for lunar mining and other exploration ideas.

The MOM orbiter was designed and developed by the Indian Space Research Organization (ISRO), India’s space agency, which released the image on Sept. 29.
Even more impressive is that MOM’s Martian portrait shows a dramatic view of a huge dust storm swirling over a large patch of the planet’s Northern Hemisphere against the blackness of space. Luckily, NASA’s Opportunity and Curiosity surface rovers are nowhere nearby.
“Something’s brewing here!” ISRO tweeted.
The southern polar ice cap is also clearly visible.
It was taken by the probe’s on-board Mars Color Camera from a very high altitude of 74,500 kilometers.

When MOM met Mars, the thrusters placed the probe into a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km. The inclination of the orbit with respect to the equatorial plane of Mars is 150 degrees, as intended, ISRO reported.
So the Red Planet portrait was captured nearly at apoapsis.
This is the third MOM image released by ISRO thus far, and my personal favorite. And its very reminiscent of whole globe Mars shots taken by Hubble.
MOM’s goal is to study Mars’ atmosphere, surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It will also sniff for methane, a potential marker for biological activity.
The $73 million mission is expected to last at least six months.
MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.
With MOM’s arrival, India became the newest member of an elite club of only four entities who have launched probes that successfully investigated Mars – following the Soviet Union, the United States and the European Space Agency (ESA).

TORONTO, CANADA – NASA isn’t “reading too much” into a report that the Russians will spend $8 billion on the International Space Station through 2025, the head of the agency says. That date is five years past the international agreements to operate the space station.
The Russian announcement comes at a pivotal time for NASA, which is looking to extend operations on the station to at least 2024. Other space agency heads have not yet signed on. Russia is the major partner for NASA on the station, given it operates several modules and sends astronauts to and from Earth on Soyuz spacecraft.
When deputy prime minister Dmitry Rogozin made the funding announcement, said NASA administrator Charles Bolden, Rogozin was speaking of a budget request that is before the State Duma. The Duma is Russia’s lower house of government.
“I am told that’s why he said that,” Bolden said at a press conference yesterday (Sept. 29) for the International Astronomical Congress, citing a conversation he had with Bill Gerstenmaier, NASA’s human exploration associate administrator. “You shouldn’t read too much into that.”

Other member agencies of the space station gave noncommittal responses when asked if they would sign on to an extension.
“The [European] member states will be invited to give their views on what [to do] after 2020,” said Jean-Jacques Dordain, who heads the European Space Agency. He added that any extension would require a financial commitment, as an agreement without money is “only principles.”
Similarly, Canadian Space Agency chief Walter Natynczyk said the money allocated to his agency will bring them through to 2020, but “we will have a look at the entire value proposition when we put a case before the government of Canada.”
The Russian agreement with NASA came under scrutiny earlier this year as tensions erupted in Ukraine while Russian soldiers were in the country. This year, Ukrainian Crimea was annexed to Russia to the condemnation of several countries, including the United States.
While Bolden has said relations with the Russians for the space station are still healthy, NASA suspended most science ties with the country in April. In response, Rogozin wrote a frustrated tweet saying NASA should try to send its astronauts into space using a trampoline.

CAPE CANAVERAL AIR FORCE STATION, FL – Assembly of the powerful Delta IV rocket boosting the pathfinder version of NASA’s Orion crew capsule on its maiden test flight in December has been completed.
Orion is NASA’s next generation human rated vehicle that will eventually carry America’s astronauts beyond Earth on voyages venturing farther into deep space than ever before – beyond the Moon to Asteroids, Mars and other destinations in our Solar System.
The state-of-the-art Orion spacecraft is scheduled to launch on its inaugural uncrewed mission, dubbed Exploration Flight Test-1 (EFT-1), in December 2014 atop the Delta IV Heavy rocket. It replaces NASA’s now retired space shuttle orbiters.
The triple barreled Delta IV Heavy is currently the most powerful rocket in America’s fleet following the retirement of the NASA’s Space Shuttle program.
Engineers from the rocket’s manufacturer – United Launch Alliance (ULA) – took a major step forward towards Orion’s first flight when they completed the integration of the three primary core elements of the rockets first stage with the single engine upper stage.

All of the rocket integration work and preflight processing took place inside ULA’s Horizontal Integration Facility (HIF), at Cape Canaveral Air Force Station in Florida.
Universe Today recently visited the Delta IV booster during an up close tour inside the HIF facility last week where the rocket was unveiled to the media in a horizontally stacked configuration. See my Delta IV photos herein.
The HIF building is located at Space Launch Complex 37 (SLC-37), on Cape Canaveral, a short distance away from the launch pad where the Orion EFT-1 mission will lift off on Dec. 4.
“The day-to-day processing is performed by ULA,” said Merri Anne Stowe of NASA’s Fleet Systems Integration Branch of the Launch Services Program (LSP), in a NASA statement.
“NASA’s role is to keep a watchful eye on everything and be there to help if any issues come up.”
The first stage is comprised of a trio of three Delta IV Common Booster Cores (CBCs).

Each CBC measures 134 feet in length and 17 feet in diameter. They are equipped with an RS-68 engine powered by liquid hydrogen and liquid oxygen propellants producing 656,000 pounds of thrust. Together they generate 1.96 million pounds of thrust.
This past spring I visited the HIF after the first two CBCs arrived by barge from their ULA assembly plant in Decatur, Alabama, located about 20 miles west of Huntsville.
The first CBC booster was attached to the center booster in June. The second one was attached in early August, according to ULA.
“After the three core stages went through their initial inspections and processing, the struts were attached, connecting the booster stages with the center core,” Stowe said. “All of this takes place horizontally.”
The Delta IV cryogenic second stage testing and attachment was completed in August and September. It measures 45 feet in length and 17 feet in diameter. It is equipped with a single RL10-B-2 engine, that also burns liquid hydrogen and liquid oxygen propellant and generates 25,000 pounds of thrust.
“The hardware for Exploration Flight Test-1 is coming together well,” Stowe noted in a NASA statement.
“We haven’t had to deal with any serious problems. All of the advance planning appears to be paying off.”
This same Delta IV upper stage will be used in the Block 1 version of NASA’s new heavy lift rocket, the Space Launch System (SLS).
Be sure to read my recent article detailing the ribbon cutting ceremony opening the manufacture of the SLS core stage at NASA’s Michoud Assembly Facility in New Orleans, LA. The SLS will be the most powerful rocket ever built by humans, exceeding that of the iconic Saturn V rocket that sent humans to walk on the surface of the Moon.

The Delta IV rocket will be rolled out to the SLC-37 Cape Canaveral launch pad this week.
Assembly of the Orion EFT-1 capsule and stacking atop the service module was also completed in September at the Kennedy Space Center (KSC).

It was moved about 1 mile to its next stop on the way to SLC-37 – the KSC fueling facility named the Payload Hazardous Servicing Facility (PHFS). Read my Orion move story here.
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.

India’s maiden interplanetary voyager, the Mars Orbiter Mission (MOM) has transmitted a breathtaking new image eyeing the limb of Mars and its atmosphere against the blackness of space.
The beautiful Martian image is only MOM’s second since successfully braking into orbit during the ‘history creating’ insertion maneuver days ago on Sept. 23/24.
The limb image was taken using MOM’s Mars Color Camera (MCC) from an altitude of 8449 kilometers and shows more of an ‘Orange Planet’ rather than a ‘Red Planet.’
“A shot of Martian atmosphere. I’m getting better at it. No pressure,” tweeted ISRO at MOM’s newly established twitter account after entering orbit.
The image has a spatial resolution of 439 meters and is centered around Lat: 20.01N and Lon:31.54E.
MOM’s goal is to study Mars atmosphere , surface environments, morphology, and mineralogy with a 15 kg (33 lb) suite of five indigenously built science instruments. It will also sniff for methane, a potential marker for biological activity.
“The view is nice up here,” ISRO tweeted.
MOM’s first image taken shortly after orbital arrival showed a heavily cratered region of the Red Planet taken by the MCC tri-color camera from a slightly lower altitude of 7300 kilometers with a spatial resolution of 376 meters.

Following MOM’s successful Mars Orbital Insertion (MOI) maneuver, India became the newest member of an elite club of only four entities who have launched probes that successfully investigated Mars – following the Soviet Union, the United States and the European Space Agency (ESA).
Read my complete MOM meets Mars arrival story – here.
MOM is now circling Mars in a highly elliptical orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km. The inclination of orbit with respect to the equatorial plane of Mars is 150 degree, as intended, ISRO reports.
The $73 million mission is expected to last at least six months.
MOM’s success follows closely on the heels of NASA’s MAVEN orbiter which also successfully achieved orbit barely two days earlier on Sept. 21 and could last 10 years or more.
