It's not likely cell phone companies will set up service on the planet anytime soon, but a network could certainly help the National Aeronautics and Space Administration as it sends rovers to explore the remote and often rocky terrain, said Steve Horan, director of the Center for Space Telemetering and Telecommunications Systems at New Mexico State University.

"Rovers and sensor networks have a very limited amount of power," said Steve Horan, professor of electrical engineering and director of the Center for Space Telemetering and Telecommunications Systems at NMSU."It is very difficult to transmit data with so little power."
Future expeditions to Mars are expected to deploy not only mobile rovers, but also fixed sensors that can help planetary scientists measure things such as the temperature and atmospheric properties.Rather than having each of these devices individually transmit data back to Earth, Horan said a system needs to be developed in which information gathered would be transmitted to a base station where it would be collected and sent back to Earth.
Horan and Phillip DeLeon, associate professor of electrical engineering, have a three-year, $650,000 grant from NASA to study technologies that might work for such a system.

Horan and DeLeon said much of the technology already developed for the telecommunications industry can be applied to this problem.

While a lot of existing technology could be used on Mars, Horan noted that much of it will have to be modified to survive conditions in space.Horan also noted that the techniques they are developing could also be applied to probes put down on the moon or on moons of other planets.

It's not likely cell phone companies will set up service on the planet anytime soon, but a network could certainly help the National Aeronautics and Space Administration as it sends rovers to explore the remote and often rocky terrain, said Steve Horan, director of the Center for Space Telemetering and Telecommunications Systems at New Mexico State University.
Horan and colleague Phillip DeLeon, an associate professor of electrical engineering, are working on a $650,000 three-year grant from NASA to develop the first cell phone coverage map of Mars - and tweak wireless communication technologies to make them work better across the planet.

"One of the big problems with the Mars Exploration Rovers mission is the long delay time between when you send a command to a rover and when it gets back," Horan said."That time can range from nine to 20 minutes.If the rover goes out of communication range before you can talk to it, that could mean the end of the mission."
The drawback means the rovers can only travel short distances on flat surfaces, but the work by New Mexico State University could change that.It could let rovers move into rockier terrain more quickly without fear of losing communications - a threat that could easily leave a rover dead on the ground, Horan said.
...
The engineers have sought terrain in New Mexico that looks similar to parts of Mars so they can track that scattering and see how and where the signals might move, Horan said.
"It's not 100 percent, but there are a lot of places in New Mexico with big rock outcroppings with no vegetation on them, like Mars," Horan said."We send signals and take data readings in those areas, then put them into a central database and computer model that can predict what will likely happen on Mars."
The computer model also lets the researchers put in different planetary conditions, such as thin atmosphere and iron-rich soil, Horan said.
Real terrain maps of Mars imaged by NASA are the backbone of the model, but once all the data is collected and entered into the system, the university will be able to give its sponsor back a full-fledged cell phone coverage map of the planet, Horan said.
The engineers are also tweaking some retail wireless communications technologies to make them work better on the planet.They are reprogramming the systems and changing the times and signals that they use to optimize them for conditions on Mars, he said.
"We hope it will help NASA go to new interesting places on Mars with rocky terrain," Horan said.
