LASP scientists Robert Ergun and Richard Eastes have been recognized by NASA for their enduring contributions to their respective fields in recent ceremonies at the agency’s Goddard Spaceflight Center in Greenbelt, Maryland.
Ergun, also a professor in the CU Boulder Astrophysical and Planetary Sciences Department, was awarded the NASA Distinguished Public Service Medal for designing and building innovative electric field instruments for many NASA flight missions, including the MAVEN Mars mission and the Parker Solar Probe, currently making record-breaking close-in orbits of the Sun. The Distinguished Public Service Medal is NASA’s highest form of recognition awarded to a non-government individual whose service, ability, or vision has personally contributed to NASA’s advancement of the U.S.’s interests.
Eastes, who currently serves as the principal investigator for the LASP-built GOLD instrument, was recognized with the NASA Exceptional Public Service Medal for his work on GOLD and a career devoted to better understanding the complex dynamics of the Earth’s near-space boundary. The Exceptional Public Service Medal is awarded to a non-government individual for sustained performance that embodies multiple contributions on NASA projects, programs, or initiatives.
A first-of-its-kind camera developed in partnership between CU Boulder and Ball Aerospace will soon be landing on the moon.
NASA announced today that it has selected a scientific instrument, called the Lunar Compact Infrared Imaging System (L-CIRiS), for its Commercial Lunar Payload Services program. The camera will ride along with one of three robotic landers that will touch down on the lunar surface in the next several years—a key step in NASA’s goal of sending people back to the moon by 2024.
LASP planetary scientist Paul Hayne, who is leading the development of the instrument, said that the goal is to collect better maps of the lunar surface to understand how it formed and its geologic history. L-CIRiS will use infrared technology to map the temperatures of the shadows and boulders that dot the lunar surface in greater detail than any images to date.
Today, NASA’s MAVEN spacecraft celebrates four years in orbit studying the upper atmosphere of the Red Planet and how it interacts with the Sun and the solar wind. To mark the occasion, the team has released a selfie image of the spacecraft at Mars.
MAVEN’s selfie was made by looking at ultraviolet wavelengths of sunlight reflected off of components of the spacecraft. The image was obtained with the Imaging Ultraviolet Spectrograph (IUVS) instrument, built at LASP, that normally looks at ultraviolet emissions from the Martian upper atmosphere. The IUVS instrument is mounted on a platform at the end of a 1.2-m boom (its own “selfie stick”), and by rotating around the boom can look back at the spacecraft. The selfie was made from 21 different images, obtained with the IUVS in different orientations, that have been stitched together.
A team led by LASP scientists, engineers, and students has been selected to build a tiny orbiting satellite to study the evaporating atmospheres of gigantic “hot Jupiters”—distant gaseous planets orbiting scorchingly close to their parent stars.
To date more than 100 gas giants have been discovered orbiting very close to their parent stars, said LASP planetary scientist, Kevin France, principal investigator on the four-year, $3.3 million effort funded by NASA. France and his colleagues believe the new study of hot Jupiters—some of which are so close to parent stars they orbit them in a matter of days—will help planetary scientists better understand the evolution of our own solar system.
LASP planetary scientist Larry Esposito has been eying the fabulous rings of Saturn for much of his career, beginning as a team scientist on NASA’s Pioneer 11 mission when he discovered the planet’s faint F ring in 1979.
He followed that up with observations of Jupiter’s and Saturn’s rings from the Voyager and Galileo spacecraft, which carried instruments designed and built at LASP. Now, as the principal investigator for the Ultraviolet Imaging Spectrograph (UVIS) on the Cassini-Huygens mission to Saturn, Esposito and his Cassini colleagues are feeling a bit somber as the mission nears its end. The spacecraft has run out of fuel and will disintegrate in Saturn’s dense atmosphere early on the morning of Sept. 15.
After a decade-long voyage through the solar system, NASA’s New Horizons mission is scheduled to fly by Pluto in July 2015, carrying with it the LASP-built Student Dust Counter (SDC). The New Horizons mission also involves LASP scientists and CU-Boulder students, who await data from the unprecedented approach and close encounter of the dwarf planet and its five known moons.
In preparation for the July encounter, LASP Office of Communications and Outreach staff recently traveled to two rural Colorado communities and delivered Pluto-related programming to students and their families. Accompanying them was Fran Bagenal, LASP planetary scientist, CU-Boulder professor of astrophysical and planetary sciences, and New Horizons mission co-investigator. Bagenal served as the New Horizons and Pluto science expert during the school visits and gave public presentations to both communities.
