Nearly 40 years after the Apollo astronauts first brought samples of the Moon to Earth for study, researchers from Washington University in St. Louis are leading an effort to return to the Moon for samples that could unlock secrets of the early Solar System. Known as MoonRise, the proposed Moon mission is one of three finalists now bidding to become NASA’s next big space science venture, a $650 million mission that would launch before 2019.

David Kilper / WUSTL PhotoFailure at a university is a word with bad connotations, unless you are involved in building experimental satellites that the U.S. Air Force and NASA find interesting. An aerospace engineer at Washington University in St. Louis who works with students building experimental spacecraft says student-built spacecraft, which he calls “university-class,” have a strong advantage over aerospace industry-built spacecraft: the freedom to fail.

Aria-9, a joint Washington University/NASA K-12 research project, is scheduled for mid-December; it involves measuring galactic cosmic rays.An estimated 1,000 students from 28 K-12 schools from Missouri, Illinois, Washington D.C., New Jersey, Montana, and Queensland, Australia are participating in Aria-9, student experiment packages that get tested on NASA space flights. The Aria-9 is the latest Washington University in St. Louis Project Aria’s “fly-and-compare” K-12 experiment packages, according to Keith Bennett, adjunct assistant professor of computer science and engineering at Washington University in St. Louis, and Aria project director.
A levitated droplet during heating by a laser to just above the melting temperature.Using the Electrostatic Levitator at NASA’s Marshall Space Flight Center, a physicist at Washington University in St. Louis led a research team that validated a 50-year-old hypothesis explaining how liquid metals resist turning into solids. The research, led by Ken Kelton, Ph.D., a professor of physics in Arts & Sciences at Washington University, is featured in the July 2003 issue of Physics Today, including an image on the magazine’s cover of a solid drop of metal suspended inside the levitator. The NASA-funded research challenges theories about how crystals form by a process called nucleation, important in everything from materials to biological systems.”Nucleation is everywhere,” says Kelton. “It’s the major way physical systems change from one phase to another. The better we understand it, the better we can tailor the properties of materials to meet specific needs.”
