Good Morning, Space Station!
It’s sunrise from space – one of 16 that occur daily as the massive lab complex orbits the Earth about every 90 minutes while traveling swiftly at about 17,500 mph and an altitude of about 250 miles (400 kilometers).
Just stare in amazement at this gorgeous sunrise view of “Our Beautiful Earth” taken earlier today, Jan. 3, 2015, aboard the International Space Station (ISS) by crewmate and NASA astronaut Barry “Butch” Wilmore.
And smack dab in the middle is the Canadian-built robotic arm that will soon snatch a soaring Dragon!
Wilmore is the commander of the ISS Expedition 42 crew of six astronauts and cosmonauts hailing from three nations: America, Russia and Italy.
He is accompanied by astronauts Terry Virts from NASA and Samantha Cristoforetti from the European Space Agency (ESA) as well as by cosmonauts Aleksandr Samokutyayev, Yelena Serova, and Anton Shkaplerov from Russia.
All told the crew of four men and two women see 16 sunrises and 16 sunsets each day. During the daylight periods, temperatures reach 200 ºC, while temperatures plunge drastically during the night periods to -200 ºC.
Here’s another beautiful ISS sunset view captured on Christmas by Terry Virts:

Virts tweeted the picture and wrote: “Sunrise on Christmas morning – better than any present I could ask for!!!!”
Another treasure from Virts shows the many splendid glorious colors of Earth seen from space but not from the ground:

“In space you see intense colors, shades of blue that I’d never seen before,” says Virts from his social media accounts (http://instagram.com/astro_terry/) (http://instagram.com/iss).
“It’s been said a thousand times but it’s true: There are no borders that you can see from space, just one beautiful planet,” he says. “If everyone saw the Earth through that lens I think it would be a much better place.”
And many of the crews best images are taken from or of the 7 windowed Cupola.

And they all eagerly await the launch and arrival of a Dragon! Indeed it’s the SpaceX cargo Dragon currently slated for liftoff in three days on Tuesday, Jan. 6.
Weather odds are currently 60% favorable for launch of the unmanned space station resupply ship on the SpaceX CRS-5 mission.
The launch was postponed from Dec. 19 when a static fire test of the first stage engines on Dec. 17 shut down prematurely.
A second static fire test of the SpaceX Falcon 9 went the full duration of approximately 3 seconds and cleared the path for a liftoff attempt after the Christmas holidays.

CRS-5 is slated to blast off at 6:20 a.m. EST Tuesday, Jan. 6, 2015, atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida.
NASA Television live launch coverage begins at 5 a.m. EST.
Assuming all goes well, Dragon will rendezvous at the ISS on Thursday, Jan. 8, for grappling and berthing by the astronauts maneuvering the 57 foot-long (22 m) Canadian built robotic arm.
Remember that you can always try and catch of glimpse of the ISS flying overhead by checking NASA’s Spot the Station website with a complete list of locations.
And don’t forget to catch up on the Christmas holiday and New Year’s 2015 imagery and festivities from the station crews in my recent stories – here, here and here.
Stay tuned here for Ken’s continuing Earth and planetary science and human spaceflight news.
A new Avengers movie. A reboot of the Star Wars franchise. The final installment of the Hunger Games. The Martian makes it to the big screen. Yup, even if the zombie apocalypse occurs in 2015, it’ll still be a great year. But trading science fiction for fact, we’re also on track for a spectacular year in space science and exploration as well.
Humanity will get its first good look at Ceres and Pluto, giving us science writers some new pics to use instead of the same half dozen blurry dots and artist’s conceptions. SpaceX will also attempt a daring landing on a sea platform, and long duration missions aboard the International Space Station will get underway. And key technology headed to space and on Earth may lead the way to opening up the window of gravitational wave astronomy on the universe. Here’s 10 sure-fire bets to watch for in the coming year from Universe Today:

10. LISA Pathfinder
A precursor to a full-fledged gravitational wave detector in space, LISA Pathfinder will be launching atop a Vega rocket from Kourou, French Guiana in July 2015. LISA stands for the Laser Interferometer Space Antenna, and the Pathfinder mission will journey to the L1 Lagrange point between the Earth and the Sun to test key technologies. LISA Pathfinder will pave the way for the full fledged LISA space platform, a series of three free flying spacecraft proposed for launch in the 2030s.

9. AdLIGO Goes Online
And speaking of gravitational waves, we may finally get the first direct detection of the same in 2015, when Advanced LIGO is set to go online. Comprised of two L-shaped detectors, one based in Livingston Louisiana, and another in Hanford Washington, AdLIGO will feature ten times the sensitivity of the original LIGO observatory. In fact, as was the case of the hunt for the Higgs-Boson by CERN, a non-detection of gravitational waves by AdLIGO would be a much stranger result!

8. Hubble Turns 25
Launched on April 24th, 1990 aboard the Space Shuttle Discovery, the Hubble Space Telescope celebrates 25 years in space in 2015. The final servicing mission in 2009 gave Hubble a reprieve from the space junk scrap heap, and the orbiting telescope is still going strong. Hubble has no less than pushed the limits in modern astronomy to become a modern icon of the space age.

7. The End of MESSENGER
NASA’s Mercury exploring spacecraft wraps up its mission next year. Launched in 2004, MESSENGER arrived in orbit around Mercury after a series of flybys on March 18th, 2011. MESSENGER has mapped the innermost world in detail, and studied the space environment and geology of Mercury. In late March 2015, MESSENGER will achieve one final first, when it impacts the surface of Mercury at the end of its extended mission.

6. Akatsuki at Venus
This Japanese spacecraft missed orbital insertion a few years back, but gets a second chance at life in 2015. Launched in 2010 atop an H-IIA rocket from the Tanegashima Space Center in Japan, Akatsuki failed to enter orbit around Venus at the end of 2010, and instead headed out for a heliocentric path around the Sun. Some quick thinking by JAXA engineers led to a plan to attempt to place Akatsuki in Venusian orbit in November 2015. This would be a first for the Japanese space agency, as attempts by JAXA at placing a spacecraft in orbit around another planet – including the Mars Nozomi probe – have thus far failed.

5. SpaceX to Attempt to Land on a Sea Platform
It’ll definitely rock if they pull it off next week: on January 6th, a SpaceX Falcon 9 rocket will lift off from Cape Canaveral with its Dragon spacecraft headed to the International Space Station on mission CRS-5. Sure, these resupply missions are becoming routine, but after liftoff, SpaceX is attempting something new and daring: landing the Falcon-9 first stage Buck Rodgers style, “fins first” on a floating barge. This is the next step in ultimately proving the feasibility of having the rocket fly back to the launch site for eventual reuse. If nothing else, expect some stunning video of the attempt soon!

4. NASA to Decide on an Asteroid Mission
Some major decisions as to the fate and the future of manned space exploration are due next year, as NASA is expected to decide on the course of action for its Asteroid Redirect Mission. The current timeline calls for the test of the SLS rocket in 2018, and the launch of a spacecraft to recover an asteroid and place it in orbit around the Moon in 2019. If all goes according to plan – a plan which could always shift with the political winds and future changes in administrations – we could see astronauts exploring a captured asteroid by the early 2020s.

3. Long Duration ISS Missions
Beginning in 2015, astronauts and cosmonauts will begin year-long stays aboard the ISS to study the effects of long duration space missions. In March of 2015, cosmonaut Mikhail Korniyenko and U.S. astronaut Scott Kelly will launch as part of Expedition 43 headed to the ISS. The Russians have conducted stays in space longer than a year aboard the Mir space station, but Kelly’s stay aboard the ISS will set a duration record for NASA astronauts. Perhaps, a simulated “Mars mission” aboard the ISS could be possible in the coming years?

2. Dawn at Ceres
Fresh off of exploring Vesta, NASA’s Dawn spacecraft will become the first mission to enter orbit around a second object, the asteroid 1 Ceres next year in April 2015. The largest asteroid and the first object of its kind discovered on the first day of the 19th century, Ceres looks to be a fascinating world in its own right. Does it possess water ice? Active geology? Moons of its own? If Dawn’s performance at Vesta was any indication, we’re in for another exhilarating round of space exploration!

1. New Horizons at Pluto
An easy No. 1,we finally get our first good look at Pluto in July, as NASA’s New Horizons spacecraft flies less than 14,000 kilometres from the surface of the distant world. Launched in 2006, New Horizons will “thread the needle” between Pluto and Charon in a flurry of activity as it passes by. New Horizons will then turn back as it passes into the shadows of Pluto and Charon and actually view the two worlds as they occult the distant Sun. And from there, New Horizons will head out to explore Kuiper Belt Objects of opportunity.
And these are just the top stories that are slated to be big news in space in 2015. Remember, another Chelyabinsk meteor or the next big comet could drop by at any time… space news can be unpredictable, and its doubtless that 2015 will have lots more surprises in store.

KENNEDY SPACE CENTER, FL – Due to technical problems encountered during a hot fire test of the first stage engines this week with the SpaceX Falcon 9 rocket, the planned Dec. 19 launch of the commercial rocket and NASA contracted Dragon cargo freighter to the International Space Station (ISS) on a critical resupply mission has been postponed a few weeks into the new year to Jan. 6 at the earliest “out of an abundance of caution,” SpaceX officials told Universe Today.
Prior to every launch, SpaceX performs an internally required full countdown dress rehearsal and hot fire test of the first stage propulsion systems.
The hot fire test attempted on Tuesday “did not run for its full duration” of about three seconds, SpaceX spokesman John Taylor confirmed to me.
Therefore SpaceX and NASA managers decided to postpone the launch in order to run another static fire test.
“We are opting to execute a second static fire test prior to launch,” Taylor said.
Due to the large amount of work required to test and analyze all rocket systems and the impending Christmas holidays, the earliest opportunity to launch is Jan. 6.

The SpaceX Falcon 9 rocket carrying the Dragon cargo freighter had been slated to liftoff on its next unmanned cargo run dubbed CRS-5 to the ISS under NASA’s Commercial Resupply Services (CRS) contract.
Here is the full update from SpaceX.
“While the recent static fire test accomplished nearly all of our goals, the test did not run the full duration. The data suggests we could push forward without a second attempt, but out of an abundance of caution, we are opting to execute a second static fire test prior to launch.”
“Given the extra time needed for data review and testing, coupled with the limited launch date availability due to the holidays and other restrictions, our earliest launch opportunity is now Jan. 6 with Jan. 7 as a backup.

“The ISS orbits through a high beta angle period a few times a year. This is where the angle between the ISS orbital plane and the sun is high, resulting in the ISS’ being in almost constant sunlight for a 10 day period.
“During this time, there are thermal and operational constraints that prohibit Dragon from being allowed to berth with the ISS. This high beta period runs from 12/28/14-1/7/15”
“Note that for a launch on 1/6 , Dragon berths on 1/8.”
“Both Falcon 9 and Dragon remain in good health, and our teams are looking forward to launch just after the New Year.”

SpaceX was founded by Elon Musk in 2002 with a dream of making commercial space exploration a reality. Since that time, Musk has seen his company become a major player in the aerospace industry, landing contracts with various governments, NASA, and other private space companies to put satellites in orbit and ferry supplies to the International Space Station.
But 2014 was undoubtedly their most lucrative year to date. In September, the company (along with Boeing) signed a contract with NASA for $6.8 billion to develop space vehicles that would bring astronauts to and from the ISS by 2017 and end the nation’s reliance on Russia.
And this past week, the company announced a plan to expand operations at its Rocket Development and Test Facility in McGregor, Texas. This move, which is costing the company a cool $46 million, is expected to create 300 new full-time jobs in the community and expand testing and development even further.
According to Mike Copeland of the Waco Tribute, an additional $1.5 million in funding could be allocated from McLennon County. This would give SpaceX a total of $3 million in funds from the Waco-McLennan County Economic Development Corportation, a fund which is used to attract and keep industry in the region.

Copeland also indicates that a report prepared by the Waco City Council specified what types of jobs would be created. Apparently, SpaceX is is need of additional engineers, technicians and industry professionals. No doubt, this planned expansion has much to do with the company meeting its new contractual obligations with NASA.
Originally built in 2003, the Rocket Development and Test Facility has been the site of some exciting events over the years. Using rocket test stands, the company has conducted several low-altitude Vertical Takeoff and Vertical Landing (VTVL) test flights with the Falcon 9 Grasshopper rocket. In addition, the McGregor facility is used for post-flight disassembly and defueling of the Dragon spacecraft.
In the past ten years, SpaceX has also made numerous expansions and improvements to the facility, effectively doubling the size of the facility by purchasing several pieces of adjacent farmland. As of September 2013, the facility measured 900 acres (360 hectares). But by early 2014, the company had more than quadrupled its lease in McGregor, to a total of 4,280 acres.
Though far removed from the company’s rocket building facilities at their headquarters in Hawthorne, California, the facility plays an important role in the development of their space capsule and reusable rocket systems. According to SpaceX’s company website, “Every Merlin engine that powers the Falcon 9 rocket and every Draco thruster that controls the Dragon spacecraft is tested on one of 11 test stands.”

In short, the facility is the key testing grounds for all SpaceX technology. And now that the company is actively collaborating with NASA to restore indigenous space-launch ability to the US, more testing will be needed. Much has been made about the company’s efforts with VTVL rocket systems – such as the Falcon 9 Grasshopper (pictured above) – but the Dragon V2 takes things to another level.
As revealed by SpaceX in May of this year, the Dragon V2 capsule is designed to ferry crew members and supplies into orbit, and then land propulsively (i.e. under its own power) back to Earth before refueling and flying again. This is made possible thanks to the addition of eight side-mounted SuperDraco engines.
Compared to the standard Draco Engine, which is designed to give the Dragon Capsule (and the upper stages of the Falcon 9 rocket) attitude control in space, the SuperDraco is 100 times more powerful.
According to SpaceX, each SuperDraco is capable of producing 16,000 pounds of thrust and can be restarted multiple times if necessary. In addition, the engines have the ability to deep throttle, providing astronauts with precise control and enormous power.
With eight engines in total, that would provide a Dragon V2 with 120,000 pounds of axial thrust, giving it the ability to land anywhere without the need of a parachute (though they do come equipped with a backup chute).
Between this and ongoing developments with the Falcon 9 reusable rocket system, employees in McGregor are likely to have their hands full in the coming years. The expansion is expected to be complete by 2018.

Concluding a busy five week mission, the SpaceX Dragon CRS-4 commercial cargo ship departed the International Space Station (ISS) this morning, Oct. 25, after delivering a slew of some 2.5 tons of ground breaking science experiments and critical supplies that also inaugurated a new era in Earth science at the massive orbiting outpost following installation of the ISS-RapidScat payload.
Dragon was released from the snares of the station’s robotic arm at 9: 57 a.m. EDT while soaring some 250 mi (400 km) over the northwest coast of Australia.
It returned safely to Earth with a splashdown in the Pacific Ocean some six hours later, capping the fourth of SpaceX’s twelve contracted station resupply missions for NASA through 2016.
“The Dragon is free!” exclaimed NASA commentator Rob Navias during a live broadcast on NASA TV following the ungrappling this morning. “The release was very clean.”

The private resupply ship was loaded for return to Earth with more than 3,276 pounds of NASA cargo and science samples from the station crew’s investigations on “human research, biology and biotechnology studies, physical science investigations, and education activities sponsored by NASA and the Center for the Advancement of Science in Space, the nonprofit organization responsible for managing research aboard the U.S. national laboratory portion of the space station,” said NASA.
The release set up a quick series of three burns by the ship’s Draco thrusters designed to carry Dragon safely away from the station.
NASA astronauts Reid Wiseman and Butch Wilmore quickly retracted the arm working from their robotics workstation in the domed Cupola module.
“Thanks for the help down there,” the astronauts radioed. “It was a great day.”

The first burn took place a minute later at about 9:58 a.m. EDT and the second at about 10:00 a.m. A yaw maneuver at 10:05 a.m. set up the orientation required for the third burn at about 10:08 a.m.
Dragon moved away quickly during the nighttime release and was already outside the Keep Out Sphere (KOS), an imaginary bubble surrounding the station at a distance of 200 m. It disappeared quickly in the dark and was barely visible within minutes.
“The propulsion systems are in good shape,” said Navias. “All systems on Dragon are functioning perfectly.”
With Dragon safely gone following the trio of burns, the next major event was the deorbit burn at 2:43 p.m. EDT at a distance of about 90 statute miles from the station.
Dragon slipped out of orbit. After surviving the scorching heat of reentry through the Earth’s atmosphere, the ship sequentially deployed its drogue chutes and three main parachutes at about 3:30 p.m.
Splashdown in the Pacific Ocean occurred as expected at about 3:39 p.m., approximately 265 miles west of the Baja peninsula.
Dragon is the only vehicle that can return intact from the ISS with a substantial load of cargo and is carrying critical science samples for distribution to researchers.
Today’s Dragon departure starts a week of heavy traffic of comings and goings to the ISS involving a series of US and Russian unmanned cargo ships.

The Orbital Sciences Antares rocket with the commercial Cygnus cargo freighter is set to launch on Monday, Oct. 27, from NASA Wallops, VA. It will dock at the ISS on Nov. 2 at the Earth-facing port on the Harmony module just vacated by Dragon.
Russia’s Progress 56 unmanned cargo ship will also undock on Oct. 27. And Progress 57 will launch from Baikonur on Wednesday, Oct 29.
The SpaceX Dragon CRS-4 cargo resupply mission thundered to space on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida on Sept. 21.

Dragon was successfully berthed at the Harmony module on Sept. 23, 2014.
Among the nearly 5000 pounds of cargo hauled up by Dragon was as an Earth observation platform named ISS-RapidScat loaded in the unpressurized trunk section.
Also loaded aboard were a slew of science experiments, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.
It also carried the first 3-D printer to space for the first such space based studies ever attempted by the astronaut crews. The printer will remain at the station for at least the next two years.
20 mice housed in a special rodent habitat were also aboard, as well as fruit flies.
The ISS Rapid Scatterometer, or ISS-RapidScat, is NASA’s first research payload aimed at conducting near global Earth science from the station’s exterior and will be augmented with others in coming years.

The successful installation and activation of the ISS-RapidScat science instrument on the exterior of Europe’s Columbus module in late September and early October inaugurated a new era in space station science.
RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring.
The 1280 pound (580 kilogram) experimental instrument is already collecting its first science data following its recent power-on and activation at the station.

“This mission enabled research critical to achieving NASA’s goal of long-duration human spaceflight in deep space,” said Sam Scimemi, director of the International Space Station division at NASA Headquarters.
“The delivery of the ISS RapidScatterometer advances our understanding of Earth science, and the 3-D printer will enable a critical technology demonstration. Investigations in the returned cargo could aid in the development of more efficient solar cells and semiconductor-based electronics, the development of plants better suited for space, and improvements in sustainable agriculture.”
The next SpacX cargo Dragon on the CRS-5 mission is slated for launch no earlier then Dec. 9.

It is no secret that NASA is seeking out private space contractors to help bring some of its current plans to fruition. Naturally, these involve restoring indigenous launch capabilities to the US, but also include the more far-reaching goal of sending astronauts to Mars. Towards that end, NASA and SpaceX participated in an unprecedented data-sharing project that will benefit them both.

If you’re a fan of SpaceX, you’ll love the website SpaceXStats. Writ large on the site are real-time countdowns to upcoming launches, all sorts of SpaceX statistics, launch manifest info, and fun trivia (there’s a countdown to how many days until Elon Musk’s bet about getting to Mars by 2020 or 2025 expires.)
The owner of the site, Lukas Davia, recently created a fantastic Falcon 9 launch collage, which was originally posted on imgur and discussed on Reddit (where there’s a 16,000-strong SpaceX community).
Lukas told Universe Today that one r/SpaceX user recently inquired if anyone had come across SpaceX montages. “While I don’t have the time for any serious video editing, I did have enough time spare to create a photo montage,” Lukas said via email. “Since I’m the owner of spacexstats.com, I already had all the launch images and assets necessary to produce it, stored locally on my computer. Using Adobe Photoshop, the whole process took just over an hour, from a blank canvas to the final image – and didn’t require much more than layer masks and guides to create. I then submitted it to /r/SpaceX & /r/space on Reddit, where it (quite surprisingly) managed to generate over 1,300,000 views in less than 24 hours.”
He added that he does plan on producing similar SpaceX graphics and perhaps updating this one in the future, “although I fear at SpaceX’s recent launch cadence, it’ll become unsuitably wide at some point!” he said.
Be sure to click on the image above to see the full resolution size.

NASA told two companies to halt work on the next phase of its commercial crew program — the spacecraft expected to replace Russian ones ferrying astronauts to the International Space Station — because of a protest related to the contract award, according to media reports.
Sierra Nevada Corp. (SNC) filed a complaint on Sept. 26, shortly after its Dream Chaser shuttle-like design was not selected for further funding under the Commercial Crew Transportation Capability (CCtCap) phase of the program. Competitors SpaceX and Boeing each received billions of dollars for further development for their Dragon and CST-100 spacecraft, which are expected to start flying around 2017.
A Spaceflight Now report, quoting NASA spokesperson Stephanie Schierholz, said the agency told both selectees that they must “stop performance of the CCtCap contract” pending the result of the challenge, which is before the Government Accountability Office. The office’s deadline for a response is Jan. 5, the report said.
In a statement, SNC said this is the first fight it undertook in relation to a government contract in more than five decades of operations. “Inconsistencies” in the process, SNC added, prompted it to go forward with the protest:
Importantly, the official NASA solicitation for the CCtCap contract prioritized price as the primary evaluation criteria for the proposals, setting it equal to the combined value of the other two primary evaluation criteria: mission suitability and past performance. SNC’s Dream Chaser proposal was the second lowest priced proposal in the CCtCap competition. SNC’s proposal also achieved mission suitability scores comparable to the other two proposals. In fact, out of a possible 1,000 total points, the highest ranked and lowest ranked offerors were separated by a minor amount of total points and other factors were equally comparable.
NASA administrator Charles Bolden declined to comment on the situation last week in response to questions from reporters at the International Astronautical Congress in Toronto, Canada, citing the legal situation.
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).

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.

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.
Space station research

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.
