Lectures to Cover Engineering Challenges of 'Hard Rock' Science

Scientists and engineers don't always dance to the beat of the same
drum, especially when it comes to "hard rock" science -- the study of
intact, crystallized rocks on other planets, which may provide clues
to how these other worlds formed.

But how do we get to these rocks and other interesting sites? "These
scientifically rich spots pose many technological challenges for
robots and require engineering designs capable of going where no human
or robot has gone before," said Brian Wilcox, robotics engineer and
manager of the Solar System Exploration Mobility Technology Program at
NASA's Jet Propulsion Laboratory, Pasadena, Calif. "While we all
agree that reaching the most promising sites is ideal, technology
sometimes limits where and how robots will get to that science."

Wilcox will discuss the extreme engineering challenges future solar
system exploration robots will face in a pair of free lectures, on
Thursday, May 8, at JPL, and on Friday, May 9, at Pasadena City
College.

Conducting science on planetary surfaces such as Mars, Venus, Mercury
and Saturn's moon Titan can be difficult for mobile robots. So, these
science-rich targets demand a fleet of new robots capable of working
on land, in the atmosphere and below a planet's surface.

The Viking landers reached Mars in 1976 and gave us a peek at the
rocks on the red planet's surface. In 1997, the Pathfinder rover
ventured close enough to the planet to examine these rocks up close
for the first time. "Although they had the latest technology
available at the time, and despite the rich array of rocks visible
around them, the Viking landers and Sojourner rover could not do the
real "hard rock" science that the upcoming Mars Exploration Rovers
will be able to do," said Wilcox. "The twin rovers will not only be
close enough to see the rocks, but also get a glimpse inside the
rocks, much as a geologist would. Future robots will not only get
inside the rocks but pick their own landing sites in real-time."

Both lectures will begin at 7 p.m. Seating is first-come,
first-served. The Thursday lecture will be in JPL's von Karman
Auditorium. JPL is at 4800 Oak Grove Dr., off the Oak Grove Drive exit
of the 210 (Foothill) Freeway. The Friday lecture will be in Pasadena
City College's Vosloh Forum, 1570 E. Colorado Blvd. For more
information, call (818) 354-0112.

Thursday's lecture will be webcast live and available afterwards at
