New book explores ‘frontier’ metaphor in science
Leah Ceccarelli is a professor of communication and author of the book “On the Frontier of Science: An American Rhetoric of Exploration and Exploitation.” She answered a few questions about the book for UW Today.
Q: What’s the concept behind this book? Why did you write it?
A: I kept seeing appeals to the American frontier spirit in the public arguments of scientists. That rhetoric was often inspiring, giving scientists an exciting image of their work across the metaphorical “boundaries” of knowledge. But it was also troubling in the expectations it set out about the manifest destiny of scientists to push forward at all costs, and in the way it reinforced their separation from a public that funds their endeavors.

Moon: It’s the right time to return
Last week, Apollo 15 commander David R. Scott, a visiting professor at Brown and one of 12 men to walk on the Moon, addressed Professor Jim Head’s introductory geology classes. He discussed the scientific returns of the Apollo missions and encouraged students to look to Apollo as a template for future human exploration of planetary bodies.
After the near-disaster of Apollo 13, NASA’s lunar exploration program stood at a crossroads. President Kennedy’s goal of landing a man on the Moon and returning him to Earth had been achieved, and many wondered, given the dangers, if it might be time to scrap Apollo. (more…)
How Do We Know When Voyager Reaches Interstellar Space?
Whether and when NASA’s Voyager 1 spacecraft, humankind’s most distant object, broke through to interstellar space, the space between stars, has been a thorny issue. For the last year, claims have surfaced every few months that Voyager 1 has “left our solar system.” Why has the Voyager team held off from saying the craft reached interstellar space until now?
“We have been cautious because we’re dealing with one of the most important milestones in the history of exploration,” said Voyager Project Scientist Ed Stone of the California Institute of Technology in Pasadena. “Only now do we have the data — and the analysis — we needed.” (more…)
JPL, Masten Testing New Precision Landing Software
A year after NASA’s Mars rover Curiosity’s landed on Mars, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., are testing a sophisticated flight-control algorithm that could allow for even more precise, pinpoint landings of future Martian spacecraft.
Flight testing of the new Fuel Optimal Large Divert Guidance algorithm – G-FOLD for short – for planetary pinpoint landing is being conducted jointly by JPL engineers in cooperation with Masten Space Systems in Mojave, Calif., using Masten’s XA-0.1B “Xombie” vertical-launch, vertical-landing experimental rocket.

The New Face of Mining: Women Carving Out a Place in Surging Industry
The UA department of mining and geological engineering, one of only 14 U.S. schools offering mining engineering degrees and only a handful with its own student mine, is dedicated to helping fill the industry pipeline, and that includes ensuring female engineers continue to gain ground in a surging industry.
They roam the remotest corners of the world, scale the highest mountains and descend deep into the Earth.
They go places few women have ever gone. They are not afraid of getting dirty, or of much else for that matter, certainly not adversity or a good challenge. And they know, better than most, how and when to take a joke. (more…)
Spacecraft Observes Evolution of Conditions at Edge of Solar System
WASHINGTON — Conditions at the edge of our solar system may be much more dynamic than previously thought, new observations suggest. Future exploration missions are expected to benefit in design and mission objectives from a better understanding of the changing conditions in this boundary region. (more…)
