The crew of Endeavour said on Wednesday (Jan 20) that construction of new coolant hoses required to connect the new Tranquility module, or Node 3, to the space station is running ahead of schedule and they are optimistic for an on time launch of the STS 130 mission currently set for Feb 7.

Shortly after I attended the rollout to pad 39 A, the launch was thrown into doubt when a set of the 14 ft long external ammonia jumper hoses, which convey coolent critical for temperature control, ruptured during high pressure testing in early January. Tranquility cannot be fully activated until the ammonia lines are installed and functioning properly. Since then, tiger teams of engineers and technicians working at the hose subcontractor and at NASA’s Marshall Spaceflight Center in Huntsville, Ala have worked vigorously to qualify four new replacement hoses. They are also working to modify the original ammonia hoses which will be brought along as a back-up “Plan B” in case problems develop with the new replacement hoses.

During a launch pad press conference with reporters, lead Endeavour spacewalker Robert Behnken said, “We’ve been following these ammonia lines and the story associated with them for 13 months. I think folks paying close attention right now haven’t really heard the entire story. So we’ve been watching them closely for a long time now.”

“Last weekend our crew was at Marshall to see the first line as it was coming together and actually put it on a test rig to make sure it was going to do the job that it was intended. We’re expecting this Saturday to fly up and see all four lines in a pretty good configuration, pretty flight representative. Those lines, after that, will come down here to KSC for processing and installation into the orbiter.”

“Right now, the schedule appears for that set of lines to be a couple of days ahead,” Behnken added. “Our original plan was to do our fit check and our opportunity with them next weekend. But they’re ahead now and we’ll be able to do that this Saturday, which is great news.”

“The program is also pursuing a second set of lines that would allow us to launch at a slightly delayed launch date and still maintain a full capability for Node 3 [Tranquility]. So the program is pursuing two courses. Plan 1 is actually ahead of schedule which allows us to do a fit check a week early. That’s really good news as we move forward to flight”, he concluded.

Tranquility is the primary cargo being lofted in the payload bay of shuttle Endeavour and will be delivered to the International Space Station by the six person crew. During three spacewalks, astronaut teams will attach and activate Tranquility and the Cupola observation module which is joined to Tranquility at one end. The modules were loaded into Endeavour’s payload bay on Wednesday (Jan. 20). See my recent photos of Tranquility and Cupola from inside the Space Station Processing Facility at KSC in earlier reports here and here.

Today (Jan 21), the STS 130 astronauts took part in a mock countdown known as the TCDT, or Terminal Countdown Demonstration Test. While dressed in their orange spacesuits they climbed inside Endeavour at pad 39 A to rehearse all the actual launch procedures right up to the T minus 4 minute point , but not including the point of liftoff. They also practiced emergency evacuation safety procedures in case of a launch pad abort requiring them to rapidly depart the orbiter in a life or death situation and enter the slidewire escape baskets. The crew flies back to Houston on Friday for final pre flight training exercises.

The six person crew comprises of commander George “Zambo” Zamka, pilot Terry Virts, and mission specialists Kathryn Hire, Stephen Robinson, Nicholas Patrick and Robert Behnken.

Senior shuttle managers will meet at KSC on Jan. 27 for an executive-level Flight Readiness Review. They will conduct an in-depth assessment to determine whether the shuttle, crew, payloads and the problematical ammonia lines are fit for launch. Thereafter the team will set an official launch date, which for now is still targeted for Feb 7.

Meanwhile it’s likewise been a busy time up in space for the 5 man crew of Expedition 22 currently in residence aboard the ISS as they conduct essential preparatory work over the next few days which must be completed before Endeavour launches and also to free up the docking port for Tranquility.

ISS commander Jeffrey Williams and cosmonaut Max Suraev boarded their Soyuz TMA-16 spacecraft today in order to relocate it to a different docking port. First they undocked from the aft port of the Russian built Zvezda service command module and then maneuvered the capsule over to redock at the Poisk module, which is russia’s newest pressurized module and which is connected to Zvezdas zenith, space facing port. This marked the first spacecraft docking at Poisk.

NASA’s Bargain Basement Artifact Sale

NASA

If there were to be an advertisement from NASA for this initiative, it would read as follows: “NASA’s Bargain Basement – Get your artifacts now! For a limited time only, “Crazy Charlie Bolden” is slashing prices at NASA for artifacts from historic space missions!! Act within the next 90 days and pay only shipping!!!”

If you thought obtaining the old Shuttles was cheap, qualified museums, educational institutions and other organizations are able to request over 2,500 artifacts from current and past NASA programs that include the space shuttle, Hubble Space Telescope, Apollo, Mercury and Gemini, all for the cost of shipping and processing.

Unfortunately for space enthusiasts looking to get in on the liquidation, a prescreening registration program will allow only those U.S. institutions that qualify to view and request the items. But, if you are part of one of these qualifying entities, act now, as each artifact is only available for viewing and requests for 90 days, starting last Tuesday, January 19th.

In all seriousness, this is a wonderful opportunity for educational organizations like museums and schools to acquire historic items from human spaceflight programs. The artifacts will include astronaut suits and suit-mockups, some shuttle assembly pieces, and scale models of the various space vehicles used in historic space missions. Any organizations wishing to request artifacts can go to the General Services Administration site that NASA has set up for the program.

After the requests have been processed, each organization will be notified of the status of their request. All items will be provided by NASA as donation, and the organizations receiving the artifacts will only be responsible for shipping and processing, which will vary with the size and type of artifact. Obviously, if you request a spacesuit, the shipping will be far less than for a piece of hardware that was used on one of the shuttles.

This is the second “clearance sale” that NASA has initiated recently. 913 artifacts were screened from October 1st to November 30th of last year, and NASA donated all 913 artifacts to various organizations after that program.

If Phoenix Arises, Science could flow quickly

If the miraculous happens and contact is unexpectedly re-established with NASA’s Phoenix Mars Lander, science could flow almost instantly if the ships vital operating systems are healthy. Indeed a science plan could be swiftly put in place after determining the condition of the lander, says Doug McCuiston, director of Mars Exploration at NASA Headquarters. McCuiston explained to me in an interview that the initial science would be “a surface change and atmospheric imaging campaign that could begin nearly immediately. In that instance, if the cameras are operable it is easy to begin an imaging campaign with real-time planning”.

A robust and wide ranging science agenda far beyond pictures could theoretically be implemented if Phoenix does amazingly survive and the pre-programmed Lazarus mode kicks in and she re-awakens with a functional arm. The goal would be to restart the assessment of habitability in the martian arctic where humanity in the form of a robotic surrogate first touched water beyond earth.

The two principal science instruments, TEGA and MECA, each have unexploited analysis cells which could potentially be loaded with fresh martian soil samples and checked for signatures of water, organics and nutrients. Peter Smith, Phoenix Principal Investigator from the University of Arizona, confirmed to me that the single unopened TEGA oven could be used, if still intact. The one remaining MECA wet chemistry cell could also potentially be utilized. Michael Hecht, lead scientist for MECA at JPL, told me that “in theory” fresh soil samples could be dropped as well onto the two microscope slides that were initially used for atmospheric air-fall samples rather than dirt droppings. High powered examinations with both the optical and atomic force microscopes might also resume. High resolution panoramic pictures would be taken by the stereo imaging system. Close up shots could be snapped by the robotic arm camera. See my Phoenix mosaics here in prepared in collaboration with Marco Di Lorenzo.

In fact, no one on the team really expects Phoenix to revive following the exceedingly harsh winter weather she has had to endure since falling silent more than one year ago on November 2, 2008. “Keep in mind, we think the chances are very low that it survived [martian] winter,” McCuiston emphasized to me. “NASA hardware has never been exposed to this type of environment on Mars”.

Phoenix landed on the northern plains of the martian artic on May 25, 2008 in a polar permafrost region that proved to be within arms reach of a vast, rock hard layer of frozen water ice. She completed 5 months of intense science, accomplishing break though discoveries at a high northern latitude. She then perished exactly as foreseen when the power output from the solar arrays plunged due to the onset of harsh seasonal weather causing dimming sunlight and bitterly frigid temperatures. At that point there were 17 hours of sunlight per sol (martian day) which are 24.7 hours in duration. Phoenix exceeded her targeted lifetime by over 2 months.

And then the environmental situation turned even more dire. Temperatures plunged steeply to below minus 180 C, there was no sunlight at all for 3 months starting in April 2009 and sheets of carbon dioxide ice built up to perhaps a foot in depth and may have encased the lander at least partially. As a result the electronic wiring likely passed through a “glass transition state” and became brittle and the twin solar arrays might have snapped off.

I asked Doug about NASA’s go forward plan in the unlikely event that Phoenix arises, “It would probably take a few days at minimum to determine what Phoenix status was, and what may or may not be done with it. Viable plans cannot be generated until the condition of the lander is known, if we hear from it. So producing a plan [prior to contact] would be guesswork at best”. As for how quickly any positive announcement would be made ? McCuiston told me that, “We will go through our regular public affairs process when the project tells us contact was made—that would be very quick, probably the same day”.

Of course to accomplish anything meaningful requires money and people. So we next discussed the status of funding available from NASA and staffing from scientists. “The Mars Program held a small amount of contingency start-up funding. Additional funding would be determined based on the condition of the instruments, and the extent and value of the science that could be done”, McCuiston explained. “The science team can be rallied quickly by the PI (Principal Investigator) since all are watching progress”, he added.

Peter Smith of the University of Arizona is the scientific Principal Investigator for the Phoenix mission and the same teams spread across many institutions in the US, Canada and several countries in Europe would still be involved.

How many scientists can be supported and for how long? “That all depends on the condition of the lander and the instruments”, McCuiston said. Phoenix was an international space exploration mission led by the US and the University of Arizona with project management at JPL and in collaboration with partners from Canada, Germany, Switzerland, Denmark, Finland and Great Britain.

NASA has two spacecraft currently circling Mars in near polar orbit which will be actively searching for Phoenix, named Mars Odyssey and Mars Reconnaissance Orbiter (MRO). “We actually listen for it, not try to contact it because of the operational mode it will come up in (if it does at all)”, explained McCuiston. “Odyssey is slated to be the prime communications spacecraft”. The listening campaign with Odyssey begins on January 18 with 10+ overflights per day for three consecutive days, each of which has about a 10 minute window of opportunity, and will continue into February and March. “MRO will search on an as-available basis, depending on what else it’s doing, since its primary role is MSL landing site work. Mars Express [from ESA] is not involved”.

MRO does play another very important informational role. “They will try to image Phoenix about every 2 weeks”, McCuiston said. No one I contacted was willing to hazard a guess yet as to whether the two power producing solar arrays are still intact. “So far the MRO images have been very poor due to fog and ice. It probably won’t be very clear until February or later”.

So the odds against contact are absolutely daunting. Still we can hope and dream that Phoenix may rise one last time from the ashes and phone home to resume her glorious achievements. If Phoenix is intact, she could potentially remain active as a research outpost for a much longer time period than the first round of 5 months since she is now at an earlier point in the martian year with sunlight increasing each sol. Phoenix final move was to poke the pitch fork like TECP probe into the martian dirt before shutting down.

Many Mars scientists believe that the arctic region may be the best place to look for evidence of current life on Mars. Indeed many Phoenix scientists have concluded that the Phoenix landing site is the “most habitable” of any thus far visited by human robotic explorers.

Stay tuned and listen for Phoenix

Having Your Own Space Shuttle Just Got Cheaper

Atlantis lands following the STS-129 mission in November, 2009. Credit: NASA

[/caption]
After the space shuttle program ends, NASA hopes to sell the three slightly used remaining orbiters to educational institutions, science museums or other organizations who could publicly display them. Over a year ago, the space agency put out a request for those interested to submit proposals for owning a shuttle and said the cost would be about $42 million, which would include “safeing” an orbiter, preparing it for display and ferrying it to a U.S. destination airport. Today, however—perhaps in response to the current economic downturn — NASA has slashed the price to just $28.8 million.

The agency will now absorb the costs of safeing, will only charge for display preparation and ferrying costs.

In the original “Request for Information” back in December 2008, NASA said they were proposing the idea of selling the shuttles and wanted to “gauge the level and scope of interest of US organizations in acquiring the two other orbiters for public display once NASA’s programmatic requirements for the assets have been satisfied.”

But in this new update, NASA says they have revised the costs, and perhaps can deliver the shuttles six months earlier than previously estimated. Hmm. Sounds like a year-end clearance sale.

Only US institutions or citizens are eligible to submit proposals. Likely, only two of the shuttles will be sold, with the third expected to remain in government hands, possibly on display in Washington, DC. “NASA advised Congress that it would begin discussions with the Smithsonian Institution regarding accession of a flown orbiter to the national collection,” the agency said in the 2008 document.

Previously, NASA has donated historically important space hardware for free. Saturn rockets, lunar modules and other artifacts from the Apollo era are on display at various locations including the Kennedy Space Centre, in Florida, the Smithsonian National Air and Space Museum, in Washington DC, and the US Space and Rocket Center, in Alabama.

If you could own a shuttle, which would you choose: Atlantis, Discovery or Endeavour?

End of Shuttle Program Will Slow Florida’s Economy

NASA’s Space Shuttle, which will make its last flight sometime later this year, has been a boon to the local economy surrounding the Kennedy Space Center, which is located in Cocoa, Florida. The closest county, Brevard, is where many of the workers that help maintain and launch the shuttle reside, and because of the presence of the space center, many a bar, restaurant, and local business have thrived.

This is in part due to those that work in the space industry, both for NASA itself and many of its private contractors. There are also the thousands of tourists that flock to the region to view launches and take tours of the Kennedy Space Center. All this, however, will change once the shuttle program is finished, and with five-year gap (at least) until the Constellation program gets rolling, the “Space Coast” may take quite a hit economically.

The end of the shuttle program will potentially eliminate as many as 7,000 – 8,000 jobs, some of which will need to be filled once again when the Constellation program is in full swing. But during the gap, many workers are expected to vacate the area in search of jobs elsewhere. This will impact the local economy that relies on these residents, and as many as 14,000 workers in the area may be indirectly affected.

According to a state study, in the 2008 fiscal year NASA generated $4.1 billion dollars in revenue and benefits for the state. $2.1 billion of that was in household income, and over 40,000 jobs were created due to NASA-related activities.

The local unemployment rate has already risen to 11.9 percent at present, largely due to the nationwide economic problems. Housing and construction have taken a hit as well, and will continue to suffer as the area sees the space workers leave.

This is the second time in NASA’s history that they’ve had to wind down a human space program, the first being the Apollo missions which ended in 1972. After the end of Apollo, Brevard county saw a dramatic downturn in the economy, as 10,000 workers left the region to find jobs and unemployment rose to 15 percent.

Estimations of the economic aftereffects of the end of the shuttle program aren’t as grim as those figures for the post-Apollo period, but there will be repercussions nonetheless.

There are several other factors that complicate the renewal of these lost jobs once the Constellation program starts up in earnest. Since Constellation utilizes a non-reusable launch system, fewer workers will be needed for repair and retrofit between launches.

Frank DiBello of the state agency Space Florida told Florida Today, “There is no escaping the transition that will occur when we go from a very labor intensive, reusable space flight system to one that is expendable. Simply by its nature, it is going to take a smaller workforce.”

Almost one-third of the current NASA employees working on the shuttle are up for retirement, so these posts would have been vacated anyway, and approximately 2,000 civil servants for NASA will retain their jobs over the gap between programs.

Though the region surrounding the Kennedy Space Center will surely struggle these next few years, it’s possible that many aerospace workers will flock to the private space industry during the gap, and companies like Virgin Galactic will benefit.

Cocaine Found In Shuttle Processing Facility

Orbiter Processing Facility at KSC. Credit: NASA

[/caption]
A small amount of cocaine was found in a restricted area of the processing hangar for shuttle Discovery at Kennedy Space Center, NASA is launching an extensive investigation into the incident. KSC spokeswoman Lisa Malone said the substance was found by a United Space Alliance worker in a hallway outside two bathrooms and a janitor’s closet, in an area where workers have to swipe their identification cards to enter. Every one of the approximately 200 people who were in the Orbital Processing Facility 3 would be easily identified, NASA says, and added Discovery’s planned launch in March should not be impacted by this event.

“This is a rare and isolated incident, and I’m disappointed that it happened, but it should not detract from the outstanding work that is being done by a dedicated team on a daily basis,” Kennedy Space
Center Director Bob Cabana said. “We are conducting an investigation and working with center security and law enforcement officials to get to the bottom of it. We have multiple checks and balances in place to ensure the work on the orbiter is done correctly, and I have no concern for Discovery’s fitness for flight.”

While there are no indications anyone who was working on Discovery was under the influence of any illegal substances, drug testing of personnel who were in that area has been conducted. Drug-sniffing dogs were immediately called in to check out the employees, but found nothing.

NASA said extensive efforts are being made to ensure flight hardware and equipment that will be used by astronauts on Discovery’s upcoming STS-131 mission are completely safe.

“We have processes that will ensure the integrity of the shuttle,” Cabana said. “There is no reason whatsoever to believe this incident will have any impact on Discovery’s upcoming launch.”

Meticulous records are kept on all work that is performed. Shuttle safety and quality assurance teams have the capability to trace individuals’ work in detail. In addition, most work tasks are reviewed and approved by one, and sometimes two, quality inspectors and specialists who verify proper work was done on critical flight hardware.

Where To Next for NASA’s Solar System Exploration?

From top to bottom, pictured are the moon, Venus, and an asteroid.From top to bottom, pictured (not to scale) are the moon, Venus, and an asteroid. These three celestial bodies from our solar system are possible candidates for NASA's next space venture.

Where is NASA going next to probe our solar system? The space agency announced today they have selected three proposals as candidates for the agency’s next space venture to another celestial body in our solar system. The proposed missions would probe the atmosphere composition and crust of Venus; return a piece of a near-Earth asteroid for analysis; or drop a robotic lander into a basin at the moon’s south pole to return lunar rocks back to Earth for study. All three sound exciting!

Here are the finalists:

Surface and Atmosphere Geochemical Explorer, or SAGE, mission to Venus would release a probe to descend through the planet’s atmosphere. During descent, instruments would conduct extensive measurements of the atmosphere’s composition and obtain meteorological data. The probe then would land on the surface of Venus, where its abrading tool would expose both a weathered and a pristine surface area to measure its composition and mineralogy. Scientists hope to understand the origin of Venus and why it is so different from Earth. Larry Esposito of the University of Colorado in Boulder, is the principal investigator.

Origins Spectral Interpretation Resource Identification Security Regolith Explorer spacecraft, called Osiris-Rex, would rendezvous and orbit a primitive asteroid. After extensive measurements, instruments would collect more than two ounces of material from the asteriod’s surface for return to Earth. The returned samples would help scientists better undertand and answer long-held questions about the formation of our solar system and the origin of complex molecules necessary for life. Michael Drake, of the University of Arizona in Tucson, is the principal investigator.

MoonRise: Lunar South Pole-Aitken Basin Sample Return Mission would place a lander in a broad basin near the moon’s south pole and return approximately two pounds of lunar materials for study. This region of the lunar surface is believed to harbor rocks excavated from the moon’s mantle. The samples would provide new insight into the early history of the Earth-moon system. Bradley Jolliff, of Washington University in St. Louis, is the principal investigator.

The final project will be selected in mid-2011, and for now, the three finalists will receive approximately $3.3 million in 2010 to conduct a 12-month mission concept study that focuses on implementation feasibility, cost, management and technical plans. Studies also will include plans for educational outreach and small business opportunities.

The selected mission must be ready for launch no later than Dec. 30, 2018. Mission cost, excluding the launch vehicle, is limited to $650 million.

“These are projects that inspire and excite young scientists, engineers and the public,” said Ed Weiler, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington. “These three proposals provide the best science value among eight submitted to NASA this year.”

The final selection will become the third mission in the program. New Horizons, launched in 2006, will fly by the Pluto-Charon system in 2015 then target another Kuiper Belt object for study. The second mission, called Juno, is designed to orbit Jupiter from pole to pole for the first time, conducting an in-depth study of the giant planet’s atmosphere and interior. It is slated for launch in August 2011.

Mars 2016 Methane Orbiter: Searching for Signs of Life

Elements of the ESA-NASA ExoMars program 2016-2018. Credit: ESA

[/caption]

The new joint Mars exploration program of NASA and ESA is quickly pushing forward to implement an agreed upon framework to construct an ambitious new generation of red planet orbiters and landers starting with the 2016 and 2018 launch windows.

The European-led ExoMars Trace Gas Mission Orbiter (TGM) has been selected as the first spacecraft of the joint initiative and is set to launch in January 2016 aboard a NASA supplied Atlas 5 rocket for a 9 month cruise to Mars. The purpose is to study trace gases in the martian atmosphere, in particular the sources and concentration of methane which has significant biological implications. Variable amounts of methane have been detected by a martian orbiter and ground based telescopes on earth. The orbiter will likely be accompanied by a small static lander provided by ESA and dubbed the Entry, Descent and Landing Demonstrator Module (EDM).

The NASA Mars Program is shifting its science strategy to coincide with the new joint venture with ESA and also to build upon recent discoveries from the current international fleet of martian orbiters and surface explorers Spirit, Opportunity and Phoenix (see my earlier mars mosaics). Doug McCuiston, NASA’s director of Mars Exploration at NASA HQ told me in an interview that, “NASA is progressing quickly from ‘Follow the Water’ through assessing habitability and on to a theme of ‘Seeking the Signs of Life’. Looking directly for life is probably a needle in the haystack, but the signatures of past or present life may be more wide spread through organics, methane sources, etc”.

NASA and ESA will issue an “Announcement of Opportunity for the orbiter in January 2010” soliciting proposals for a suite of science instruments according to McCuiston. “The science instruments will be competitively selected. They are open to participation by US scientists who can also serve as the Principal Investigators (PI’s)”. Proposals are due in 3 months and will be jointly evaluated by NASA and ESA. Instrument selections are targeted for announcement in July 2010 and the entire cost of the NASA funded instruments is cost capped at $100 million.

“The 2016 mission must still be formally approved by NASA after a Preliminary Design Review, which will occur either in late 2010 or early 2011. Funding until then is covered in the Mars Program’s Next Decade wedge, where all new-start missions reside until approved, or not, by the Agency”, McCuiston told me. ESA’s Council of Ministers just gave the “green light” and formally approved an initial budget of 850 million euros ($1.2 Billion) to start implementing their ExoMars program for the 2016 and 2018 missions on 17 December at ESA Headquarters in Paris, France. Another 150 million euros will be requested within two years to complete the funding requirement for both missions.

ESA has had to repeatedly delay its own ExoMars spacecraft program since it was announced several years ago due to growing complexity, insufficient budgets and technical challenges resulting in a de-scoping of the science objectives and a reduction in weight of the landed science payload. The ExoMars rover was originally scheduled to launch in 2009 and is now set for 2018 as part of the new architecture.

The Trace Gas orbiter combines elements of ESA’s earlier proposed ExoMars orbiter and NASA’s proposed Mars Science Orbiter. As currently envisioned the spacecraft will have a mass of about 1100 kg and carry a roughly 115 kg science payload, the minimum deemed necessary to accomplish its goals. The instruments must be highly sensitive in order to be capable of detecting the identity and extremely low concentration of atmospheric trace gases, characterizing the spatial and temporal variation of methane and other important species, locating the source origin of the trace gases and determining if they are caused by biologic or geologic processes. Current photochemical models cannot explain the presence of methane in the martain atmosphere nor its rapid appearance and destruction in space, time or quantity.

Among the instruments planned are a trace gas detector and mapper, a thermal infrared imager and both a wide angle camera and a high resolution stereo color camera (1 – 2 meter resolution). “All the data will be jointly shared and will comply with NASA’s policies on fully open access and posting into the Planetary Data System”, said McCuiston.
Another key objective of the orbiter will be to establish a data relay capability for all surface missions up to 2022, starting with 2016 lander and two rovers slotted for 2018. This timeframe could potentially coincide with Mars Sample Return missions, a long sought goal of many scientists.

If the budget allows, ESA plans to piggyback a small companion lander (EDM) which would test critical technologies for future missions. McCuiston informed me that, “The objective of this ESA Technology Demonstrator is validating the ability to land moderate payloads, so the landing site selection will not be science-driven. So expect something like Meridiani or Gusev—large, flat and safe. NASA will assist ESA engineering as requested, and within ITAR constraints.” EDM will use parachutes, radar and clusters of pulsing liquid propulsion thrusters to land.

“ESA plans a competitive call for instruments on their 3-4 kg payload”, McCuiston explained. “The Announcement of Opportunity will be open to US proposers as well so there may be some US PI’s. ESA wants a camera to ‘prove’ they got to the ground. Otherwise there is no significant role planned for NASA in the EDM”.

The lander would likely function as a weather station and be relatively short lived, perhaps 8 Sols or martian days, depending on the capacity of the batteries. ESA is not including a long term power source, such as from solar arrays, so the surface science will thus be limited in duration.

The orbiter and lander would separate upon arrival at Mars. The orbiter will use a series of aerobraking maneuvers to eventually settle into a 400 km high circular science orbit inclined at about 74 degrees.

The joint Mars architecture was formally agreed upon last summer at a bilateral meeting between Ed Weiler (NASA) and David Southwood (ESA) in Plymouth, UK. Weiler is NASA’s Associate Administrator for the Science Mission Directorate and Southwood is ESA’s Director of Science and Robotic Exploration. They signed an agreement creating the Mars Exploration Joint Initiative (MEJI) which essentially weds the Mars programs of NASA and ESA and delineates their respective program responsibilities and goals.

“The key to moving forward on Mars exploration is international collaboration with Europe”, Weiler said to me in an interview. “We don’t have enough money to do these missions separately. The easy things have been done and the new ones are more complex and expensive. Cost overruns on Mars Science Lab (MSL) have created budgetary problems for future mars missions”. To pay for the MSL overrun, funds have to be taken from future mars budget allocations from fiscal years 2010 to 2014.

“2016 is a logical starting point to work together. NASA can have a 2016 mission if we work with Europe but not if we work alone. We can do so much more by working together since we both have the same objectives scientifically and want to carry out the same types of mission”. Weiler and Southwood instructed their respective science teams to meet and lay out a realistic and scientifically justifiable approach. Weiler explained to me that his goal and hope was to reinstate an exciting Mars architecture with new spacecraft launching at every opportunity which occurs every 26 months and which advance the state of the art for science. “It’s very important to demonstrate a critical new technology on each succeeding mission”.

Latest Buzz: NASA to Get Bigger Budget and New Launcher

OK, I guess I was wrong yesterday when I said nothing happened during the meeting between President Obama and NASA Administrator Charlie Bolden. Science Magazine has now published this:

President Barack Obama will ask Congress next year to fund a new heavy-lift launcher to take humans to the moon, asteroids, and the moons of Mars, ScienceInsider has learned. The president chose the new direction for the U.S. human space flight program Wednesday at a White House meeting with NASA Administrator Charles Bolden, according to officials familiar with the discussion. NASA would receive an additional $1 billion in 2011 both to get the new launcher on track and to bolster the agency’s fleet of robotic Earth-monitoring spacecraft.


If this is true, it would mean Ares would be scrapped for another, simpler heavy-lift vehicle that could be ready to fly as early as 2018. Science News also said that European countries, Japan, and Canada would be asked to work on a lunar lander and modules for a moon base, saving the U.S. several billion dollars, and commercial companies would take over the job of getting supplies to the international space station.

So, what about the “flexible path” suggested by the Augustine Commission? If this plan is implemented, U.S. partners focus on lunar exploration, and NASA — while helping out with the Moon missions, might also focus on missions to asteroids and Phobos and Deimos to prepare for a later human landing on the Red Planet in the distant future. To prepare for human visits, NASA may order additional robotic missions to the martian moons and asteroids in coming years.

Nothing’s official yet; we’ll have to wait and see what actually transpires….

Obama and Bolden Meet. So What Happened?

US President Barack Obama’s met with NASA administrator Charlie Bolden on Wednesday at the White House. What happened? Not much, as far as anyone can tell. The meeting was short, and no real details have emerged of what might have been discussed or decided. “The two spoke about the Administrator’s work at NASA and they also discussed the Augustine Committee’s analysis,” a White House spokesman told Florida Today. “The President confirmed his commitment to human space exploration, and the goal of ensuring that the nation is on a sustainable path to achieving our aspirations in space.”

The Hunstville Times reported that the two also discussed options for how the country might improve its future human spaceflight activities.

So, no announcement on what “path” NASA will take as a result of the Augustine Commission, or if the Constellation program is staying or going.

While earlier this week, there was hope that Wednesday’s meeting might result in an announcement of NASA’s future, now there are hints that perhaps such an announcement might be part of the State of the Union Address in January, or perhaps a statement regarding the President’s decisions on NASA won’t come until sometime in February.

The U.S. Senate approved a budget of $18.7 billion that the President needs to make a decision on. But The Orlando Sentinel reported that also on Wednesday, Bolden told lawmakers and Congressional staff that the White House was now favoring a $1 billion top line increase to NASA’s budget in 2011. This would be far better than the 5 percent cut that all agencies, including NASA, were asked by the White House to prepare, but difficult to secure given the current deficit-cutting mindset in Congress.

Space Politics also reported on that on Wednesday, unfortunately, Speaker of the House Nancy Pelosi said she was not a “big fan” of human spaceflight. “I have not been a big fan of manned expeditions to outer space, in terms of safety and cost,” she said. “But people could make the case; technology is always changing.”
Any additional spending for NASA, she said, would have to be evaluated against other programs, and “a judgment will be made as to what it does in terms of job creation.” She added that while human missions to the Moon “would be fine” but appeared to be more skeptical about “personned” missions to Mars.

So for now, we wait. Some more.
