Or, more appropriately, Voyager 1 is cooling its instruments. To help conserve power, the mission managers at NASA have decided to cut the electricity to a heating element – one that’s part of the nearby infrared spectrometer that’s not been in operation for some 14 years. This power cut will lower the temperature of the ultraviolet spectrometer by about 23 degrees Celsius (41 degrees Fahrenheit)… a temperature that’s mild compared to the below minus 79 degrees Celsius (minus 110 degrees Fahrenheit) that the instrument has dropped to in previous times. It’s not a drastic measure, however, but all part of a crucial plan to manage electrical power to keep the spacecraft operational and transmitting data for another 13 years.

Just because the power is cut back doesn’t mean the instrument quit working. At the present, the spectrometer is continuing to gather and transmit data. The resilient system was designed to work in temperatures as frosty as minus 35 degrees Celsius (minus 31 degrees Fahrenheit) and has even operated beyond the call of duty when heaters were switched off over the last 17 years. While it was taking a chance that the equipment might malfunction, the engineering team was confident since the spectrometer has worked at minus 56 degrees Celsius (minus 69 degrees Fahrenheit.) since 2005. “The spectrometer is likely operating at a temperature somewhat lower than minus 79 degrees Celsius, or minus 110 degrees Fahrenheit,” says the team. “But the temperature detector does not go any lower.”

While it has been awhile since Voyager 1’s encounter with Jupiter and Saturn which made the spectrometer busy, that doesn’t mean its data will be disregarded. Both scientists and mission management specialists will continue to monitor performance levels and an international team of scientists will further review spectrometer data.

Live long and prosper, Voyager!

The Next Generation of Robotic Space Explorers – Powered by Bacteria!

As technology advances, a lot of the gadgets and other things we use keep getting smaller, lighter and thinner. Now that trend may soon be taken to another extreme – small robotic space explorers which in turn use a miniscule power source – bacteria.

It may sound like science fiction, or just odd even, but that is the idea behind a new proposal by NASA for an alternative to the solar and nuclear powered missions common today. The bacteria could provide a long-lived energy source which could sustain a tiny robotic probe; the amount of energy generated would also be small however, not enough to power larger probes like the Mars rovers for example. The microbial fuels cells could last a long time however, as long as the bacteria themselves had an adequate food supply.

The microbe being considered for the project is Geobacter sulfurreducens, which does not require oxygen for its survival.

A research team at the Naval Research Laboratory would like to have a working prototype of just such a robot within the next ten years that would weigh about 2 pounds (1 kilogram). There are technological hurdles, as with any new mission concept, to be overcome which will take several years.

Another major concern however, is the problem of contamination. Planetary probes, especially ones going to Mars, have been sterilized before launch according to a long-standing protocol, to minimize the introduction of earthly bacteria to the alien environments. So what would happen if a bacteria-powered probe was sent? It seems counter-productive then to deliberately send microbes which not only hitch a ride but are actually the fuel.

According to Gregory Scott at NSL: “There are planetary protection concerns, as well as concerns about protecting the microbes themselves from radiation. Sometime down the road we also have to consider whether the microbes we’re looking at are most effective for radiation environments or extreme temperatures.”

Any bacteria-based fuel system would have to take the contamination issue into account and be developed so as to try to minimize the chances of accidental leakage, especially in a place like Mars, where such organisms would have a decent chance at survival.

The concept is an innovative and exciting one, if the various technological and environmental concerns can be addressed. If so, our tiny friends may help to open a new chapter in space exploration.

Scott continues: “As we move forward in the utilisation of MFCs as an energy generation method, this research begins to lay the groundwork for low powered electronics with a long-term potential for space and robotic applications,” says Scott. Microbial fuel cells coupled with extremely low-power electronics and a low energy requirement for mobility addresses gaps in power technology applicable to all robotic systems, especially planetary robotics.”

Missions that Weren’t: NASA’s Manned Mission to Venus

[/caption]

In the mid-1960s, before any Apollo hardware had flown with a crew, NASA was looking ahead and planning its next major programs. It was a bit of a challenge. After all, how do you top landing a man on the Moon? Not wanting to start from scratch, NASA focused on possible missions that would use the hardware and software developed for the Apollo program. One mission that fit within these parameters was a manned flyby of our cosmic twin, Venus. 

As one of our neighbouring planets, a mission to Venus made sense; along with Mars, it’s the easiest planet to reach. Venus was also a mystery at the time. In 1962, the Mariner 2 spacecraft became the first interplanetary probe. It flew by Venus, gathered data on its temperature and atmospheric composition before flying off into a large heliocentric orbit. But there was more to learn, making it a destination worth visiting.

A scale comparison of terrestrial planets Mercury, Venus, Earth, and Mars. That Earth and Venus are of a similar size led many to draw comparisons between the planets before better scientific experiments revealed Venus is closer to the Earth inside out.

But beyond being relatively practical with great potential for scientific return, a manned mission to Venus would prove that NASA’s spacecraft and astronauts were up for the challenges of long-duration interplanetary flight. In short, it would give NASA something exciting to do.

The mission proposal was published early in 1967. It enhanced the Apollo spacecraft with additional modules, then took the basic outline of an Apollo mission and aimed it towards Venus instead of the Moon.

The crew would launch on a Saturn V rocket in November of 1973, a year of minimal solar activity. They would reach orbit in the same Command and Service Modules (CSM) that took Apollo to the Moon. Like on Apollo, the CSM would provide the main navigation and control for the mission.

Going to the Moon, Apollo missions had the crew turn around in the CSM to pull the LM out of its launch casing. On the mission to Venus, the crew would do the same, only instead of an LM they would dock and extract the Environmental Service Module (ESM). This larger module would supply long-duration life support and environmental control and serve as the main experiment bay.

With these two pieces mated, the upper S-IVB stage of Saturn V would propel the spacecraft towards Venus. Once its fuel store was spent, the crew would repurpose the S-IVB into an additional habitable module. Using supplies stored in the ESM, they would turn the rocket stage into their primary living and recreational space. On its outside, an array of solar panels would power each piece of the spacecraft throughout the mission.

The crew would spend 123 days traveling to Venus. Ten hours of each day would be dedicated to science, mainly observations of the solar system and beyond with a telescope mounted in the ESM. UV, X-ray, and infrared measurements could create a more complete picture of our corner of the universe. The rest of each day would be spent sleeping, eating, exercising, and relaxing — a full two hours of every day would be dedicated to unstructured leisure, a first for astronauts.

Like Mariner 2 before them, the crew would flyby Venus rather than go into orbit. They would only have 45 minutes to do close optical observations and deploy probes that would send back data on the Venusian atmosphere in realtime.

After the flyby, the spacecraft would swing around Venus and start its 273 day trip back to Earth. Like on an Apollo lunar mission, the crew would transfer back into the Command Module before reentry taking anything that had to return to Earth with them. They would jettison the S-IVB, the ESM, and the Service Module, switch the CM to battery power, and plunge through the atmosphere. Around December 1, 1974, they would splashdown somewhere in the Pacific Ocean.

Though worked out in great detail, the proposal was a thought experiment rather than something NASA was seriously considering. Nevertheless, Apollo-era technology would have managed the mission.

Good and Bad News Comes With NASA’s 2012 Budget

An Artist's Conception of the James Webb Space Telescope. Credit: ESA.

[/caption]

On November 14, President Obama signed an Appropriations bill that solidified NASA’s budget for fiscal year 2012. The space agency will get $17.8 billion. That’s $648 million less than last year’s funding and $924 million below what the President had asked for. But it’s still better than the $16.8 billion proposed earlier this year by the House of Representatives.

To most people, $17.8 billion is a huge amount of money. And it absolutely is, but not when you’re  NASA and have multiple programs and missions to fund. So where does it all go?

The bill highlights three major items when it comes to NASA’s budget. Of its total funding, $3.8 billion is set aside for Space Exploration. This includes research and development of the the Orion Multi-Purpose Crew Vehicle and Space Launch System, hopefully keeping both programs on schedule.

$4.2 billion has been allocated for Space Operations. This includes funds to tie up the loose ends of the Space Shuttle program, the end of which is expected to save more than $1 billion. The Space Operations budget, however, is $1.3 billion below last year’s level.

Coming to a very popular topic, the bill dedicates $5.1 billion to NASA Science Programs, a division that includes the James Webb Space Telescope. The JWST has garnered much attention this year, usually for being badly behind schedule and cripplingly over budget. Of the funding dedicated to Science Programs, $530 million is directed to the JWST project.

There’s a little problem hidden in this item in the bill. The $5.1 billion is just over the $150 million funding the Science Programs got last year. With $380 million on top of that increased promised to the JWST, where’s the money coming from? Other programs. As the bill says, “the agreement accommodates cost growth in the James Webb Space Telescope (JWST) by making commensurate reductions in other programs.” NASA will get the money for the telescope the only place it can – by cutting other programs.

This means potential major cuts to planetary programs since NASA’s manned program traditionally gets the most money. And understandably so. Aside from the real space enthusiasts who track robotic missions with gusto, an astronaut provides a great human link to space for the everyman. So even without an active manned program, it’s highly unlikely NASA will find the funds for the JWST program in its manned budget.

Planetary missions will likely take the hit. And a funding cut now could seriously affect NASA’s long range plans, such as its planned missions to Mars through 2020. Prospective missions to Europa will face difficulties too, a real shame since liquid water was recently discovered under the icy surface of that Jovian moon.

Unfortunately, NASA’s budget just can’t match its goals. For the near future, NASA will have to do what it can with what it’s got. As NASA Administrator Charles Bolden said in reference to the budget the House of Representatives originally proposed in February, it “requires us to live within our means so we can invest in our future.” Let’s all hope for some wise investing on NASA’s part.

Could We Soon See the End of ITAR’s Chokehold on Space Exploration?

Jeff Foust of The Space Review may have said it best when he claimed that ITAR, a set of trade regulations regarding defense-related trade, was “an acronym that has become figuratively and literally a four-letter word in the industry given the costs, delays, and general uncertainty involved in dealing with those regulations.” No matter where you are on the political spectrum or no matter where you stand on the debate about what’s next in space, you will find people who hate the ITAR’s (International Trade Arms Regulations International Traffic in Arms Regulations) influence on space commerce. Even in this time of great partisanship, Rep. Howard Berman [D-CA28] along with six Democrats and four Republicans have joined forces to craft a sword that, once given to the president will eliminate ITAR’s influence on space commercial enterprise.

The Safeguarding United States Satellite Leadership and Security Act of 2011 is the name of the bill. Also named HR 3288, the act removes spacecraft and related components from the United States Munitions List which is a list of items which are controlled by ITAR. China, Cuba, Iran, Sudan, Syria, and North Korea have restricted access to US spacecraft merchants, easing fears that US technology would fall into the wrong hands.

HR 3288 has created much excitement in the space industry.

“Congress has the opportunity to dramatically improve the competitiveness of the U.S. satellite and space industries and ensure an innovative and thriving U.S. space industrial base,” said Patricia Cooper, the president of the Satellite Industry Association, in a press release. She added that they would be jumping for joy if it weren’t for the “outmoded and overly-restrictive regulation” they say they are under.

Why so much joy? Mitchell Baroody, political analyst, advocate, speaker and told Universe Today that “while ITAR may have some positive effects on National Security, the detrimental effects of these ‘red tape-laced’ regulations cannot be ignored.”

For instance, according to The Space Review in 2006, U.S. Satellite Manufacturers have estimated losses from ‘$2.5 and $6.0 billion since 1999 due primarily to ITAR regulations.’

“When industries become over-regulated, this is what happens,” Barody said. “As a result of ITAR, even…‘friendly’ foreign countries are weary of dealing with the U.S.”

This makes it difficult for our allies because spacecraft are listed after deadly toxicological agents and before destructive nuclear weapons with all three under the same trade rules. Despite this hilarious position, spacecraft’s removal is still, according to Space Politics, “an uphill battle, as Congress awaits the administration’s export control reform proposals as well as delivery of a final version of a report looking at the national security implications of moving satellite export control reform.”

This uphill struggle against protectionism might not be so bad because over the overwhelming need to create jobs. Baroody acknowledged that there are “many who are advocating protectionist ideals, like Donald Trump advocating increased trade tariffs of 25% with China in April of 2011.”

However, Baroody said, there are many more who know that in the present American economy, people are looking for any feasible solution to export control that has economic benefits. “Unfortunately, becoming more protectionist could have some very negative economic implications for the American consumer,” he said.

Baroody does not foresee this bill being stopped by the protectionist movement. “HR 3288 does not, in any way, benefit the one country who has been treating us unfairly, China,” he said. “This bill should not face an obstacle, in reference to protectionism.”

To Baroody, the thought “that idealists tendencies, which are not accurate, can dominate and win over more jobs, more freedom for American business, and more money in the pockets of Americans is…sickening.”

Some could counter-claim saying national security is at risk, but Baroody thinks the US government has gone too far.

“Before the satellite industry was given such a devastating blow in 1999, it is fair to say there was not enough oversight. However, putting satellites on the munitions list went way too far,” he said. “Now, American Manufacturers are winning with HR 3288 and American security is being preserved because the malevolent nations are excluded from being sold these satellites and components.”

Drilling down to the mechanics of the law, this is the only route Congress can take to export reform as Baroody explains: “Title 22 USC § 2778 (The ITAR) gives Congress oversight in munitions list removal. The President has to present any removals to Congress and cannot remove anything until 30 days have passed upon notification of the Speaker and specific committees. They specifically authorized the President to have discretion in removal. In HR 3288, Congress authorizes the President to remove the satellites and related components only if this does not cause a threat to National security.” In other words, congress can’t remove the spacecraft from the munitions list themselves.”

The Safeguarding United States Satellite Leadership and Security Act of 2011 is not perfect. “The bill includes risk-mitigating licensing controls, procedures, and safeguards,” Baroody said. “Red-tape and regulations are always going to get in the way of commerce, regardless of whether it involves space or some other category of commerce. If you put aside the risk mitigating licensing controls, procedures, and safeguards and look at America’s tax system, the answer is obvious.”

“The red-tape a company has to go through to get a product to market, like a satellite, can also be just as bad as paying more for it,” Baroody continued. “Having to paddle through the exorbitant amount of regulations to ensure you are legally allowed to sell your product and your buyer is allowed to keep it, is detrimental to every business. We should have regulations, but they should be within reason and should make sense. Government should not babysit our industries but they should keep an eye on them to make sure no one is getting hurt and the American people are being reasonably protected”.

This bill even has international implications. In an interview for The Space Review Dennis Burnett, vice president of trade and export controls for EADS North America expressed that “You cannot build a big sophisticated satellite without US parts and components, you just cannot do it…Those components might comprise no more than five percent of the satellite, but still, it’s a very important five percent.”

Because of this international impact, the bill was referred to the Foreign Affairs Committee on November 1st. This so called ‘Congress of specialists’ will, if they give the bill their time, study the bill then report on it. If the committee doesn’t give the bill their time, it will die there. Only after the committee’s review will there be a vote on the elimination of the ITAR.

NASA Developing Real-Life Tractor Beams

[/caption]

If you are a Star Trek fan, you will of course be familiar with “tractor beams,” those cool-looking laser beams that can grab an object in space and it pull backwards toward the source of the beam (including trapping spacecraft as evil aliens would often do). They are another long-running staple of science fiction that is now closer to science reality. NASA is now working on developing just such technology, which would help primarily in obtaining material samples in real-life space missions, such as on Mars or an asteroid or comet.

A $100,000 study to look at three possible methods has been awarded to NASA’s Goddard Space Flight Center by the NASA Office of the Chief Technologist (OCT). According to Principal Investigator Paul Stysley, “Though a mainstay in science fiction, and Star Trek in particular, laser-based trapping isn’t fanciful or beyond current technological know-how.”

The methods being developed can trap and move particles of matter or even single molecules, viruses or cells, using the power of light – maybe not another spacecraft yet, but the principle is the same.

NASA has used various methods of sample-retrieving, all with great success, including aerogel on the Stardust spacecraft to obtain dust samples from the comet Wild 2 and scoops, brushes and rock abrasion tools on various Mars landers and rovers to retrieve rock and soil samples. On the next Mars rover, Curiosity, which is due to be launched later this month, there will be a scoop as well as a drill. It will also feature a laser beam to zap rocks so the resulting particles can be analyzed; not quite the same as a tractor beam but still cool.

The first technique being studied is the optical vortex or “optical tweezers” method which uses two counter-propagating beams of light. Particles are confined to the “dark core” of the overlapping beams. Particles can be moved along the ring’s centre by alternating the strength or weakness of one of the beams. The only catch with this method is that it requires an atmosphere to work. Ideal then maybe for on the surface of Mars or Titan for example, but not for an asteroid or other airless body.

The second technique uses optical solenoid beams, where the intensity peaks spiral around the axis of propagation. Particles can be pulled backwards along the entire length of the beam, and it can operate in a vacuum, no atmosphere necessary.

Both of those techniques have been tested in the laboratory, but the third method, as of yet, has not. It uses what is known as a Bessel beam, which, when projected onto a wall for example, features rings of light surrounding the central dot of light. The effect is similar to looking at ripples surrounding the spot where a pebble has been dropped into a pool of water. Other types of laser beams do not exhibit that however, appearing only as a single point of light. Such a beam could induce electric and magnetic fields in the path of an object, which could then pull the object backwards.

According to team member Barry Coyle, “We want to make sure we thoroughly understand these methods. We have hope that one of these will work for our purposes.” He added, “We’re at the starting gate on this. This is a new application that no one has claimed yet.”

A more technical overview of the practicality of tractor beams is here.

Boeing To Use Shuttle Hangar for CST-100 Space Taxi

CAPE CANAVERAL, Fla – NASA hosted an event on Monday, Oct. 31, at 10 a.m. EDT at Kennedy Space Center’s Orbiter Processing Facility-3 (OPF-3) to announce a new partnership between NASA, Space Florida and Boeing. Space Florida in turn will lease OPF-3 to Boeing. Under the terms of this arrangement, Boeing will use OPF-3 to manufacture and test Boeing’s “space taxi” the CST-100.

Boeing will use OPF-3 as the firm’s commercial crew program office. The OPF, essentially a hangar, will be converted to construct Boeing’s CST-100 space capsule, which is currently being developed to deliver astronauts to low-Earth-orbit (LEO).

In the past Boeing has issued imagery that displayed its CST-100 launching from a variety of different launch vehicles which call Florida's Space Coast their home. Photo Credit: Boeing

This new partnership was developed following a Notice of Availability that the space agency issued at the beginning of this year. The notice was used to identify interest from industry for space processing and support facilities at Kennedy. With NASA’s fleet of orbiters being decommissioned, NASA was seeking ways to effectively use its existing facilities.

It is hoped that this, and similar partnerships will help create jobs in the region as well as to help the U.S. regain leadership in the global space economy.

Boeing's CST-100 is called a "space-taxi" and is being designed to carry both crew and cargo to both the International Space Station as well and other low-Earth-orbit destnations. Image Credit: Boeing

The CST-100 is currently proposed as a reusable spacecraft that is comprised of two parts – a crew module and service module. It is designed to house up to seven astronauts, but it can also be used to ferry both people and cargo to orbit.

With the space shuttle fleet retired, NASA is completely reliant on Russia for access to the International Space Station. Russia charges the space agency about $63 million a seat on its Soyuz spacecraft.

“Only Congress can determine when we will stop the investment of our nation’s tax dollars into the purchase of continued space transportation services from the Russians – and invest instead in the U.S. work force and commercial industry capabilities,” said Space Florida’s President Frank DiBello.

NASA has worked to keep the public apprised about its efforts to open its doors to private space companies. The space agency held press conferences to announce both the Space Act Agreement (SAA) that NASA had entered into with Alliant Techsystems (ATK) and EADS Astrium concerning the Liberty launch vehicle, as well as the release of the design of the Space Launch System (SLS) heavy-lift rocket (which was announced on the following day).

“Thanks so much John and John, I love what you have done with the place!” said NASA Deputy Administrator Lori Garver referring to OPF-3.

The CST-100 has been proposed as a means of transportation to other future destinations in low-Earth-orbit such as one of the inflatable space station's currently under development by Bigelow Aerospace. Image Credit: Boeing

Space Florida is the organization that works to maintain and cultivate the aerospace industry within the State of Florida. The purpose of NASA’s Commercial Crew Program is to develop U.S. commercial crew space flight capabilities. It is hoped that they will one day allow the U.S. to achieve reliable, safe and cheap access not to just the space station – but other destinations in LEO as well.

“If we’re going to find a way to fund exploration beyond the vicinity of Earth, particularly in today’s fiscally-constrained environment – we’ve got to find a way to do the job of transporting crew to the International Space Station in a more affordable manner,” said Boeing’s John Elbon. “That’s one of the primary purposes of the commercial crew program – to provide affordable access to low-Earth-orbit so that we can use the International Space Station as the great laboratory that it is.”

Through an agreement with Space Florida, NASA will lease Orbiter Processing Facility-3 (OPF-3) to Boeing for its CST-100 space taxi. It is hoped that this and efforts like this one will eventually reduce the cost of sending crews to the International Space Station. Photo Credit: NASA

Science Fiction No More: Humans and Robots to Explore Space Together

When you hear about robots and space exploration, the first thing many people may think of is R2-D2 and C-3PO from Star Wars. While we may not be quite there yet, robots have become a major, even necessary, part of space missions. The many probes, landers and rovers that have been sent throughout the solar system are essentially robots, which have become more advanced over time. Then there’s the new Robonaut, a humanoid robot designed to assist astronauts with a variety of tasks in space including on the International Space Station, for example. But what is next? That was the subject of a panel discussion last Tuesday at the Von Braun Memorial Symposium in Huntsville, Alabama. The future being planned by the robotics experts involved is one of both humans and robots working together in space. The future is now…

“Can we have both robotics and human exploration of space?” was the question of the day. While there have long been advocates of both, there has also been a prevailing debate over which is better; robotic missions are less expensive and don’t put people in danger, but there are some things that only humans could do efficiently and quickly. The rovers on Mars for example, have done an amazing job of exploring the Martian surface, although human astronauts could do a lot of the same tasks faster. Also of course, people can experience the wonder and excitement of exploration in a way that machines can’t.

Instead of choosing between the two scenarios, the best idea, which I personally agree with, is to do both in tandem. That was the focus and apparent consensus of the symposium, that the best way forward is for humans and robots to work together, complimenting each others’ strengths and weaknesses. Humans might be better suited for on-site detailed exploration such as sample-taking, while robots could better handle other, more dangerous jobs.

The use of robotics has become a “pervasive technology across both military and space” according to Dr. Suzy Young of UA-Tuscaloosa’s Research Office. She also cited sources which claim that robotic intelligence could start to approach that of humans by 2040. It may still sound like science fiction, but it is quickly becoming science fact. Maybe those lovable droids from Star Wars aren’t too far off now after all.

Do You Have Ideas for Deep Space Travel? NASA Wants to Hear from You

You’ve probably heard by now how NASA is going to focus more on deep space exploration, both manned and robotic, leaving the low-Earth orbit and suborbital realms to commercial companies, a major change. There is, however, an opportunity for public input for deep space exploration as well, thanks to a new initiative for competitive ideas from universities, students, companies and government agencies. This means that you may have a chance to forward your proposals to help solve the problems that will need to be resolved in the coming years.

NASA’s new technology offices are getting ready to spend millions of dollars, it was announced at a seminar held last Monday as part of the Von Braun Memorial Symposium in Huntsville, Alabama. NASA is hoping to get between $375 million and $560 million in the fiscal year 2012 budget, which would be enough for competition prizes of $1 million or more.

“We have a space technology program, and there’s some money behind it,” Marshall Chief Technologist Andrew Keys said at the seminar.

The new heavy-lift rocket being designed will initially cost $1 billion or more, and still use proven conventional technology for its first planned launch in 2017. But as those first rockets are then replaced by larger ones, technological challenges will have to be overcome for new, better boosters to be designed, for example, which will ne necessary to take human farther into deep space to places like Mars.

The solar sail is also a good example of new technology, which is much different from conventional rockets, using the pressure of photons emitted from the Sun for propulsion, a very novel idea which is now being proven to be both possible and useful.

As in other facets of business and technology, competition will be a good thing, helping to bring out the best ideas and concepts from a larger knowledge pool, allowing the space industry to move more quickly and efficiently into the solar system and beyond. We may not have Star Trek-style warp speed yet, but the future is looking bright for space exploration, a future that can be better shared by all of us.
