Students in some of North Carolina's elementary schools will soon begin pondering the idea of humans living on Mars. And when they do, they'll be able to draw inspiration from a play by a Winston-Salem children's theater group.

Imagine Mars -- a project sponsored by NASA, its Jet Propulsion Laboratory and the National Endowment for the Arts -- is asking students across the country to help design and share a Mars community for 100 people. (See http://imaginemars2.jpl.nasa.gov/about/index.cfm for more information.)

It has named the Open Dream Ensemble as a principal partner in the endeavor. The group, which consists of alumni from UNC School of the Arts, will present a new play called Peril on the Red Planet at schools through December and, sometimes, lead related residencies.

NASA's partnership with Open Dream was announced yesterday during a news conference at the Stevens Center.

"If you could build a community on Mars, what would it look like?" asked David Delgado, a NASA representative involved in Imagine Mars. He said that Peril helps present information about Mars in "a fun and meaningful way."

Without it, Delgado said, students "don't see the relevance of the information."

Peril will premiere at 7:30 tonight at the Stevens Center. Mayor Allen Joines has proclaimed today "Imagine Mars Day" in Winston-Salem.

Open Dream, a professional outreach program of UNCSA, consists of school alumni who studied dance, drama or music at the school and earned ensemble spots at auditions because of their proficiency in several disciplines. The performers introduce children to the live-theater experience in schools across the region.

Margaret S. Mertz is the executive director of the Thomas S. Kenan Institute for the Arts, which underwrites Open Dream.

"We're delighted that Imagine Mars has selected the Open Dream Ensemble as one of its four primary partners on the national level," Mertz said in a statement, adding that Open Dream is "the only one of the four that focuses on the artistic interpretation of the goals of the program."

Rebecca Nussbaum, Open Dream's general manager, said that Peril came about when Mertz brought the Imagine Mars project to her attention and suggested she look into creating a play about it.

Nussbaum said she and others involved in Peril consulted several times with NASA officials to ensure the accuracy of the information in it.

Peril, geared to third- through eighth-graders, will be premiered tonight after another play, titled Dream Machines: The Impossible Happens.

Peril is about Diana, 13, a girl working to end famine on Mars. She reconstructs the machine that made human habitation possible on Mars and unexpectedly unleashes more problems.

Along the way, she learns "lessons about community, responsibility, teamwork and sacrifice," according to press materials.

■ The Open Dream Ensemble will present two shows tonight in the Stevens Center,405 W. Fourth St. Dream Machines: The Impossible Happens, geared to grades K-5, will begin at 6:30 p.m. Peril on the Red Planet, geared to grades 3-8, will begin at 7:30 p.m. Both shows are free and open to the public, and the audience is welcome to attend one or both productions.

A manned asteroid mission using two Orion spacecraft, docked nose-to-nose to form a 50-ton deep space vehicle, is being studied by Lockheed Martin Space Systems as an alternative to resumption of U.S. lunar landing missions.

The Orion asteroid mission concept is being unveiled just as the Presidential committee reviewing U.S. human space flight is citing asteroid missions after 2020 as a less costly alternative to NASA's proposed lunar landing infrastructure. Results of the review will be briefed to President Obama by Norman Augustine, committee chairman, by the end of August.

If one looks closely at the graphic, a space suited astronaut deployed from the Orion, is standing atop the asteroid. The graphic is from a Lockheed Martin promotional movie that shows concepts under study by the Orion prime contractor.

Under the Bush Administration strategy, NASA had planned a resumption of lunar landing missions by about 2020 using the Orion as a lunar orbiting command ship while its crew descended to the moon in Altair landers for lengthy stays on the surface.

The official NASA line has been solidly "all moon" for the last several years, while more realistic assessments over the same period have shown that is not feasible. NASA more recently, however, had become more open about an asteroid mission capability for Orion after space scientists and planners meeting before formation of the committee began to criticize the lunar goal as too fragile.

Development and cost problems with the Ares 1 and Ares 5 launch vehicle programs have also become increasingly apparent since about 2007.

Augustine and other committee members such as former astronaut Sally Ride have already reported publicly that NASA's current plan to retire the shuttle, finish the space station and return to the moon by the early 2020s is not even remotely feasible under NASA's current funding profile.

In fact a Lockheed Martin video titled "Orion For Crewed Science Missions" shows the twin Orion configuration closely orbiting an asteroid while space suited astronauts explore its surface. With the minuscule gravity of an asteroid, astronauts flying manned maneuvering units could travel between the Orion combo and the object without ever requiring a much heavier, and expensive, asteroid landing vehicle.

The video, little noticed at the time, was shown in early August at a propulsion conference in Denver sponsored by the American Institute of Aeronautics and Astronautics. The AIAA "Joint Propulsion Conference" so called because it brings together multiple international agencies often makes news as it also did in 2008 when Chinese researchers openly discussed their scramjet technology program.

At this year's event, the Lockheed Martin video was part of a presentation delivered by former astronaut Brian Duffy, now Lockheed Martin vice president and program manager for the Altair lunar module part of the Orion lunar landing infrastructure.

Duffy's presentation also cited satellite servicing that could be performed by astronauts from an Orion configuration, equipped with a shuttle-type manipulator arm deployed from its service module.

The presentation also discussed use of single Orion spacecraft to service geosynchronous orbit military and civilian satellites and the potential for them to travel to Lagrangian points to service telescopes like the giant new Webb space telescope set for launch in about four years. Lagrangian points balance out gravity from the sun, Earth and moon allowing spacecraft to remain parked at those locations. They are about 1 million mi. from Earth, about the same distance as some asteroids passing near Earth. This means Orions configured for missions to telescopes, like Webb, at Lagrangian points would have a life support capability also generally suitable for asteroid missions.

Next Scheduled Launch Just A Week Away

While space shuttle Discovery's STS-128 launch preparations continue at Florida's Kennedy Space Center, the astronaut crew completed its final planned integrated ascent training in Houston at NASA's Johnson Space Center. Launch is planned for 0158 EDT on Monday, August 24th.

Late last week, shuttle managers approved 18 additional plug pull tests on the orbiter side of the external fuel tank to ensure there are no issues with its intertank region. Engineers at the tank's manufacturing plant in New Orleans are assessing high-tech X-ray data to ensure protective foam ramps on the tank slated for November's STS-129 mission show no defects.

The ice-frost ramps (IFR) protect brackets along the external tank from development of ice when super-cold liquid oxygen and hydrogen are loaded prior to launch. Foam loss during the last two shuttle launches from one particular IFR high up on the liquid oxygen tank has led to a detailed examination to determine if it is acceptable to launch Discovery without further work.

Meanwhile, the STS-128 crew conducted its final launch training session integrated with Mission Control before heading into quarantine Monday. They will fly to Kennedy on Wednesday to prepare for launch.

At first, it was hard for University of North Carolina football player Kendric Burney to swallow.

They handed him a pill containing a battery, thermometer and radio transmitter and told him it would lodge in his intestine, where it would stick around for one to two days to measure his core body heat.

“I’m not going to lie. The thought of putting that in my stomach was just plain weird,” said Burney, a junior cornerback.

But by gulping down the vitamin-sized CorTemp capsule, Burney and 17 other Tar Heel football players began sweating out data that will be used later this season to help determine whether higher body temperatures increase the possibility of concussions. North Carolina’s coaches also plan to use the data to better regulate drills during practice and during games in heat that often reaches the high 90s through the early stretch of fall games.

“That allows us to monitor as coaches, ‘How long do we want to do that particular type of drill?’ ” coach Butch Davis said. “What’s appropriate for a receiver might not be appropriate for an offensive lineman. So I think it’s brilliant.”

The CorTemp pill — a white, silicone-coated capsule big enough “that it feels like you’re swallowing a gummy bear,” according to offensive lineman Alan Pelc — was originally developed by NASA to measure astronauts’ body temperature in space. But over the last six years, scores of football teams have used the $40-per-pop doses to better learn how to beat the heat on the field.

It works like this: Players ingest the pills about five hours before practice; the removal of an attached magnet activates the battery. A device that looks like a remote control, held within six inches of the player, records the temperature via radio transmitter.

Researchers at NASA and the Department of Energy recently tested key technologies for developing a nuclear fission reactor that could power a human outpost on the moon or Mars. The tests prove that the agencies could build a "safe, reliable, and efficient" system by 2020, the year NASA plans to return humans to the moon.

A fission reactor works by splitting atoms and releasing energy in the form of heat, which is converted into electricity. The idea for using nuclear power in space dates back to the late 1950s, when they were considered for providing propulsion through Project Orion. In the 1960s a series of compact, experimental space nuclear reactors were developed by NASA under the Systems Nuclear Auxiliary Power program. But public safety concerns and an international treaty banning nuclear power in space stopped development.

Now nuclear power is being considered for lunar and Mars missions because, unlike alternatives such as solar power, it can provide constant energy, a necessity for human life-support systems, recharging rovers, and mining for resources. Solar power systems would also require the use of energy storage devices like batteries or fuel cells, adding unwanted mass to the system. Solar power is further limited because the moon is dark for up to 14 days at a time and has deep craters that can obscure the sun. Mars is farther away from the sun than either the Earth or the moon, so less solar power can be harvested there.

The new nuclear power system is part of a NASA project started in 2006, called Fission Surface Power, that is examining small reactors designed for use on other planets. While nuclear power remains controversial, the researchers say that the reactor would be designed to be completely safe and would be buried a safe distance from the astronauts to shield them from any radiation it would generate.

The recent tests examined technologies that would see a nuclear reactor coupled with a Stirling engine capable of producing 40 kilowatts of energy--enough to power a future lunar or Mars outpost.

"We are not building a system that needs hundreds of gigawatts of power like those that produce electricity for our cities," says Don Palac, the project manager at NASA Glenn Research Center in Cleveland, OH. The system needs to be cheap, safe, and robust and "our recent tests demonstrated that we can successfully build that," says Palac.
