Astrobotic's Guide for lunar payload developers


Lander-rover architecture by Astrobotic Technology, a leading competitor for the Google Lunar X-Prize [Astrobotic Technology, Inc.]

Astrobotic Technology today released a new guide for researchers on preparation of their instruments for the company's planned December 2013 robotic expedition to the surface of the Moon.

The expedition, based on technology from Carnegie Mellon University, will carry up to 240 pounds of science, engineering, and marketing payloads. Any university, government agency or company is eligible to purchase payload accommodations on the December 2013 flight.

"To get their sensors and experiments to the lunar surface, researchers have had to propose entire missions to space agencies such as NASA or the European Space Agency," said Astrobotic president David Gump.

"This initiative allows engineers and scientists to focus on just their own instruments, with Astrobotic providing the delivery and support utilities like power and communications. They can buy just what they need from us by the pound, watt, and byte."

Last month Astrobotic announced that it has signed a contract with SpaceX to launch its mission on a Falcon 9 rocket, the same vehicle that NASA will use to send supplies to the International Space Station. The Falcon 9 will throw the Astrobotic spacecraft into a lunar trajectory for a four-day cruise to the Moon.

Lunar landers are challenged to descend from a lunar orbit to the moon’s surface under a gravitational force of 1.62 m/s2, about one sixth the magnitude of earth gravity. The purpose of this research is to design and simulate a lunar lander model which will emulate the flight and landing of a robotic lunar spacecraft in order to test guidance, navigation and control (GNC) software.

Autonomous control will be developed for descent, soft landing and attitude control. An emulation can test lab-scale landing hardware in addition to GNC software and autonomy of a robotic lunar lander. This paper describes a design for a model lunar lander available for testing in two separate environments, one which constricts the lander models motion so a descent is not possible and another incorporates an innovative gravity offload mechanism to compensate for the lesser gravity of the Moon.

NASA offers purchase of data from private, unmanned lunar landings

Carnegie Mellon University's spin-off Astrobotics has already devoted $3,000,000 toward winning the Google Lunar X-Prize (GLXP) by December 2012 [Astrobotics].

Astrobotic Technology, the Carnegie Mellon University company devoted to lunar robotic exploration, wasted no time announcing its acceptance of NASA's offer to buy up to $10 million in data from a commercial unmanned mission to the Moon. NASA announced August 5 its Innovative Lunar Demonstrations Data (ILDD) program, with a total budget of $30 million.

Astrobotic's primary goal is to revisit the July 1969 landing site of Apollo 11 (0.67°N, 23.47°E) no later than December 2012 to win all three lunar landing cash incentives; a total $24 million in the the primary Google Lunar X Prize (GLXP) contest, the $2 million bonus prize offered by Florida if the mission is launched there, and now up to $10 million offered by NASA to buy data from the mission.

The company is one of more than twenty organizations presently qualified to compete Google-sponsored lunar lander competition managed by the X-Prize Foundation. The goals includes successfully landing a privately-funded lunar rover on the Moon and traveling at least 500 meters while returning data and televised images. A bonus prize is offered for landing near a human artifact in a manner that can be verified.

The winning plan as outlined by Astrobotic includes, "connecting the Internet to the Moon and returning 3D High-Definition to convey the experience to the world. "

Carnegie Mellon and the company have already spent over $3 million creating prototype robots together with mission designs since 2007, when the Google Lunar X Prize was first offered.

The new NASA program to purchase data from successful commercial landings will accelerate the company's work on the spacecraft, the company announced.

"Sensing devices and software needed for an automated lunar landing are evolving from our research and development on autonomous cars," said Dr. William "Red" Whittaker, Astrobotic founder, and director of CMU's Field Robotics Center. "Much of the technology for winning the DARPA (the Defense Advanced Research Projects Agency) Urban Challenge car race also applies directly to our lunar landing project."

Astrobotic and CMU are testing a prototype robotic vehicle sufficiently robust to operate in the extreme heat of two week lunar day and to survive the deeply cold, equally long lunar night.

Astrobiotics has 'Space Available'

Astrobotic Technology has carry 109 kilograms-capacity for sale as part of a payload the company is preparing to fly on a maiden voyage to the lunar surface in a 2012 bid to win the Google Lunar X Prize.

"Science instruments, prototype exploration devices and commercial packages will be carried at $700,000 per pound, plus a $250,000 fee per payload to cover engineering" costs of integrating the package with either the expedition’s solar-powered surface rover or landing bus.

"The company posted a technical description of the service on its Web site, along with a “Request for Information” asking potential users to characterize how they would use this capability," according to Astrobiotic's David Gump

"Celestis Incorporated has already reserved 11 of the 240 pounds on the initial Moon mission," Gump wrote. "Houston-based Celestis operates a space burial service for cremated remains, with eight missions thus far to the Moon, Earth orbit or a suborbital trajectory.

NASA contracts to Astrobiotics-Carnegie Mellon

NASA has selected Astrobotic Technology and Carnegie Mellon University for two contracts to study Moon excavation robots and methods to simulate the one-sixth lunar gravity on Earth.

Lightweight excavation robots are key to recovering the water and hydrocarbon deposits at the Moon's poles, which will enable explorers to "live off the land" rather than hauling all their supplies from Earth at great expense. New results from NASA probes released last week show that the water content in the polar soil is 10 to 30 times richer than previously thought, and in easier-to-access places than the floors of deep craters.

"We intend our robots to be prospectors for water and hydrocarbon resources, and then to demonstrate how they can be turned into rocket propellant and life support supplies," said Dr. William "Red" Whittaker, founder of Astrobotic Technology and a research professor at the university's Robotics Institute. "Creating propellant at the Moon will halve the cost of lunar exploration and advance the date when we can send human expeditions to Mars."

Excavation is expected to be required to remove a top layer of dry soil covering ices deposited by comet and asteroid impacts.

The lunar gravity simulation study will examine the best ways to mimic the effects of the one-sixth lunar gravity via various active and passive gravity-offload mechanisms and ways to make the apparatus scaleable and transportable for field tests in challenging terrain.

NASA selected the excavation robot proposal under its Small Business Innovation Research program and lunar-gravity simulation proposal under its Small Business Technology Transfer program designed to move university research into the commercial sphere. The two Phase I awards total $199,850 and may lead to Phase II awards in six months totaling $1.2 million.

Astrobotic Technology Inc. is a Carnegie Mellon spin-off that will fund a series of robotic Moon missions, first winning the $20 million Google prize and visiting Apollo 11 on the "Tranquility Trek" expedition in late 2011. The Trek robot will be a rolling TV studio and Internet node, sending back high-definition video of its adventures. Later missions will prospect for water ice in deep polar craters and seek out volcanic caves as low-cost shelters for both robots and astronauts.

About Astrobotic Technology:
The company has secured lunar contracts from NASA and two commercial firms. Prototype rovers are now being field-tested at Carnegie Mellon University by Dr. William "Red" Whittaker, the firm's chairman.

Astrobiotic's new lunar rover

Astrobotic Technology has revealed more information about its lunar rover. This company is led by William “Red” Whitaker and hopes to win the $20 million Lunar X Prize.

Earlier this month Astrobotic Technology unveiled the Moon Digger that they hope to use to win The NASA Regolith Excavation Challenge.

The new rover will be used to travel the moon’s equator, where it gets hotter than boiling water. The rover will keep a cool side aimed away from the sun and will generally travel east or west, but can tack north and south like a sailboat.

The robot will also serve as an internet node and be able to transmit back high resolution photographs of the moon’s surface. It will use 2 motors with bicycle like chain drives as opposed to a motor in each wheel hub.

Astrobiotics/CMU foresee role for micro-bots

Photo, above, by Mark Maxwell, Astrobotic Technology: Small commercial robots the size of riding mowers could prepare a safe landing site for NASA's lunar outpost by surrounding it with an eight-foot high semi-circle berm to block grit kicked out by spacecraft landings from hitting nearby habitats, according to research by Astrobotic Technology Inc. and Carnegie Mellon University, funded by NASA.

Astrobotic Technology and Carnegie Mellon Researchers Show Small Robots Can Prepare Lunar Surface for NASA Outpost

PITTSBURGH—Small robots the size of riding mowers could prepare a safe landing site for NASA's Moon outpost, according to a NASA-sponsored study prepared by Astrobotic Technology Inc. with technical assistance from Carnegie Mellon University's Robotics Institute.

Astrobotic Technology and Carnegie Mellon researchers analyzed mission requirements and developed the design for an innovative new type of small lunar robot under contract from NASA's Lunar Surface Systems group.

The results will be presented Friday in Washington, D.C., at a NASA Lunar Surface Systems conference co-sponsored by the U.S. Chamber of Commerce and its Space Enterprise Council.

"NASA faces a challenge in planning the layout for its outpost, which is expected to begin operations in 2020," said William "Red" Whittaker, chairman and chief technical officer of Astrobotic and a Carnegie Mellon professor of robotics. "For efficient cargo transfer, the landing site needs to be close to the outpost's crew quarters and laboratories. Each rocket landing and takeoff, however, will accelerate lunar grit outwards from the pad. With no atmosphere to slow it down, the dry soil would sandblast the outpost."

The research examined two potential solutions: 1) construction of a berm around the landing site, and 2) creation of a hard-surface landing pad using indigenous materials.

In the first solution, researchers found that two rovers weighing 330 pounds each would take less than six months to build a berm around a landing site to block the sandblasting effect. A berm 8.5 feet tall in a 160-foot semi-circle would require moving 2.6 million pounds of lunar dirt. Robots this size can be sent to NASA's planned polar outpost site in advance of human expeditions. Astrobotic Technology Inc. has proposed that landing site preparation be provided by commercial ventures.

In the second solution, researchers showed how small robots could comb the lunar soil for rocks, gathering them to pave a durable grit-free landing pad, said John Kohut, Astrobotic's chief executive officer. "This might reduce the need to build protective berms. To discern the best approach, early robotic scouting missions need to gather on-site information about the soil's cohesion levels and whether rocks and gravel of the right size can be found at the site."

Also at Carnegie Mellon, Whittaker is directing the development of Astrobotic's first lunar robot, which has been undergoing field trials for several months. The company's first mission, to win the $20 million Google Lunar X prize by visiting the Apollo 11 landing site and transmitting high-definition video to Earth, is set for December 2010.

Methane strong hint of Martian Biosphere.

Earth-based spectography has confirmed earlier hints, from probes orbiting Mars, of plumes of Methane gas, the strongest sign of a native biosphere since modern remote sensing of the fourth planet began more than forty years ago.

From the San Francisco Chronicle: The scientists, from NASA and other U.S. institutions, found high concentrations of methane that are consistent with methane plumes produced by underground bacteria on Earth.

The observations have reignited a life-on-Mars debate that began in 1996 when NASA astrobiologist David McKay and several other colleagues announced that a meteorite from Mars contained evidence of bacteria.

Since then, in absence of more substantive proof, most scientists have discounted McKay’s findings. But that may now change.

“I think this is extremely strong evidence for current life on Mars,” said McKay, who works at Johnson Space Center.

“It doesn’t prove it. But, to me, that is very strong support for the microbial life theory that we have been promoting with evidence for a number of years.”

The new methane data, collected by NASA senior scientist Michael Mumma and other planetary scientists, found that concentrations of the gas varied greatly by location and season on Mars.

The primary plume they found contained about 19,000 metric tons of methane, which is comparable to the methane produced at the large hydrocarbon seep Coal Oil Point in California, where underwater bacteria produce methane by processing hydrocarbons

Astrobotic teases with Lunar Lander shot

Yes, it looks like an updated Surveyor, just as proposed. I like it, and it resembles the ESA and JAXA long-term plans and proposals, for a reason. It will probably work.

Lander Platform with minimal solar power-in-flight and ground ops, and Four-legged, not five legged or three, with Rover deployed from on-top and, wisely perhaps, little seen of that ground vehicle from this angle.

Expect a lot of similar designs because, for the Google Lunar X-Prize mission, the vehicle-team that wins will build around the mission, and that means no need for a return flight, of course, among other things.

Google Lunar X PRIZE draws in higher education

Will universities become the platform for space research and exploration? Private companies? Or will NASA remain top dog? Will the Google Lunar X PRIZE change space exploration?

A robot is the iconic mechatronic system, and in my mind, a rocket, lander and rover destined for the moon are the ultimate mechatronic system. The craft would involve every facet of engineering, including particularly controls, fluids, thermodynamics, physics, mechanics, electronics, computers, communications, and of course trying to make everything work together — systems engineering and mechatronics. What a better place to find experts in all these varied fields than at the engineering department of a university?

I think the early favorite is Astrobotic Technology Inc., a partnership between Carnegie Mellon University, Raytheon Missile Systems, and other institutions, including the University of Arizona. The $20 million grand prize requires landing on the moon, sending various high-resolution photos, travelling 500 meters across the lunar surface and sending back high definition video.

Teams competing for the Google Lunar X PRIZE must have 90% of their funds originating from private sources. Although this competition won't change the paradigm of space exploration, I hope it will spur more private research and development, especially at the university level. This competition provides the drive for teams to create something spectacular on a potentially small budget in a relatively very short amount of time (by December 31, 2014). I think this will show other researchers, our government and universities that we have the technology and resources to get to the moon without a billion-dollar budget.

University of Arizona & Raytheon partner for X-Prize: Return to Tranquillity Base


Teamed up with Carnegie Mellon & Astrobotics

Alan Fischer - Tuscon Citizen

University of Arizona scientists and students are reaching for the moon in a quest for a $30 million payoff.

The mission, if successful, could change the way space exploration is done, help UA students find jobs and enrich southern Arizona, backers said.

The UA Lunar and Planetary Laboratory and Aerospace and Mechanical Engineering Department have teamed with Raytheon Missile Systems and Carnegie Mellon University in Pittsburgh to design, build, fly and operate a robotic lunar lander mission.

The team, called Astrobotic Technology Inc., is competing with nine other groups for the the Google Lunar X Prize, which offers a $30 million purse for the first private robotic mission to the moon that meets operational specifications.

Efforts are under way to fund the project, which is expected to cost about $100 million.

Mission plans call for landing the rover about 500 meters from the Apollo 11 landing site where in July 1969 man first visited the moon, said Dante Lauretta, deputy team leader and UA associate professor at LPL.

"I think it is going to be awe inspiring to go back and see the place where man first walked on the moon," he said.

The rover will beam a high-definition video back to Earth showing its journey on the moon's surface and the Apollo 11 lander, he said.

Some long lead time items, like the mission's launch vehicle, mean it will take about 18 months from the time full funding is secured to landing on the moon, Lauretta said.

The spacecraft will take about five days to reach the moon, about the same as the Apollo missions, Lauretta said.

The mission to the moon will be based at UA.

"We will handle the journey to the moon, descent, landing, deploy the lander and control the rover," Lauretta said.

The launch vehicle to push the craft into space will be purchased from an outside source, he said.
The remainder of the space components, including the lander and rover - to be called Artemis Lander and Red Rover - will be built and operated by the team.

The project will be based in the LPL's Science Operations Center building, which currently houses Phoenix Mars Lander mission operations, Lauretta said.

"We are going to fabricate the spacecraft on the UA campus," he said. "This will be another leap in capability for the UA."

The building, at 1415 N. Sixth Ave., will also house mission control, running the project from the time the spacecraft separates from its booster rocket until the mission is completed, he said.

"We will have a joystick and control from Earth the vehicle driving around on the moon," Lauretta said.

The project has $1.5 million in hand donated by UA, Carnegie Mellon and Raytheon to fund design work and develop a business plan needed to raise funds to cover the project's $100 million price tag, Lauretta said.

A business team including UA External Relations is working to secure sponsors and investors to fund the project, he said.

And while spending $100 million for a chance at winning a $30 million prize may seem like unsound economics to some, Lauretta said the payoff to Astrobotic, as well as to southern Arizona, could be huge.

"We are initiating a new business that involves the private sector that will carry cargo to the surface of the moon at a fraction of the cost of federal government projects," Lauretta said.

"Investors look at this not just to win $30 million. They see a new industry opening up that could have enormous potential for the future of the United States.

"The X Prize is not the only revenue stream. We will have a system for pinpoint accuracy delivery to the surface of the moon or other planets. Others will come and pay for that. We really believe in the vision of the Google Lunar X Prize to make lunar surface activities routine."

The initial mission may cost $100 million, but ensuing efforts will see the price drop, he said.

By offering a relatively inexpensive turnkey way to deliver packages to space bodies, the project could attract many customers, he said.

"Instead of being the group that provides the science instruments, we will be able to provide an entire spacecraft and run an entire mission," Lauretta said. "UA will be capable of building and operating entire space missions for NASA. We'll have a bigger share of the workload.

"This will make Tucson a kind of center for planetary exploration. It will really be a huge economic boon to the whole region."

Local team members are confident Astrobotic will succeed.

"It's a remarkable combination of talent, with Raytheon bringing serious spacecraft engineering, the University of Arizona bringing serious space science and Carnegie Mellon bringing strong expertise in robotics," said Michael J. Drake, director of UA's Lunar and Planetary Laboratory.

"It's kind of a match made in heaven."

"Looking at the other teams, we're No. 1 or No. 2 in ability to put a rover on the moon and successfully do the mission," said Dan Cheeseman, a Raytheon Missile Systems engineer who is working on the project.

The collaboration between UA and Raytheon could offer the area long-term business benefits, Drake said.

"This is a unique, very high-energy partnership between Raytheon and the UA," he said. "We're trying to figure out how we can work with Raytheon on civil space activities, which would allow us to keep more money here in southern Arizona when we make a proposal."

By providing more components and services for future space missions "in house" at UA, more mission money would be spent locally, Drake said.

For example, the UA-led Phoenix Mars Lander mission is funded by NASA for $420 million, but about $60 million of that will be spent locally with the remainder going for outsourcing the booster rocket, lander and navigation to the Martian surface where UA will take over scientific exploration.

"If we succeed this is going to be a huge boost for the space industry in Arizona," Drake said.

A close collaboration between the University of Arizona and Raytheon Missile Systems on the Google Lunar X Prize project could offer both big benefits.

Fifteen Raytheon engineers have teamed with about 40 UA Aerospace and Mechanical Engineering students to design and eventually build a landing craft to deliver a rover to the surface of the moon.

"We give them a chance to work with engineers, learn while in school what Raytheon wants and identify them as potential candidates for hiring," said Roberto Furfaro, UA engineering students program manager and assistant professor. "Raytheon is real excited about the type of work we are doing and is really evaluating these students. They are learning how Raytheon operates and when they graduate they are ready to go."

The cooperative effort offers the students a chance to work on a project that will actually go into space, said Aaron Farber, a second year AME grad student who is working on the mission's guidance, navigation and control effort.

"We've got to stop this thing and land it in an area a meter across," Farber said of the precision soft landing the program requires. "If we get it 99 percent of the way there and it doesn't stop, we don't win. We're responsible for making that happen."

Farber's GNC team is designing the thruster system for steering the craft in space and guiding it to a precise location for a soft landing on the moon's surface.

In addition to GNC, student teams are designing electrical power and thermal systems and the lander's mechanical structure.

Raytheon is supporting the program with its 15 engineers, said Dan Cheeseman, chief architect of space applications at Raytheon.

The Raytheon engineers and UA engineering students work closely together to design the craft for the mission.

"They bring a set of fresh ideas," said Chris Owan, section head for mechanical subsystem directorate at Raytheon.

The collaboration offers the students the opportunity to see how things really operate at a large company such as Raytheon, and gives Raytheon a view of how the students might fit in there, Owan said.

New engineering graduates face challenges getting up to speed in the real world, said Matt Cribb, GNC flight control section head at Raytheon.

"This gives them the practical experience they need to be marketable," Cribb said.

"This is like a once-in-a-dream opportunity. You can't buy this kind of experience," Farber said. "It's a fantastic opportunity to segue into a job."

"It's not just about going to the moon," Cheeseman told a group of the the student engineers at a Monday afternoon meeting. "It's about your careers."

The project also offers Raytheon the opportunity to move into the space exploration market, Cheeseman said.

"It could make us a player in a market we're not in right now - as an innovator," he said.

The students are making strong contributions to the project.

"When we get to the moon, it's going to be because of their effort and help," Cribb said.

The project could offer UA students, as well as Raytheon, big benefits.
