Synthetic Biology for Space Exploration
Berkeley Lab Scientists Believe Biomanufacturing a Key to Long-term Manned Space Missions
Does synthetic biology hold the key to manned space exploration of the Moon and Mars? Berkeley Lab researchers have used synthetic biology to produce an inexpensive and reliable microbial-based alternative to the world’s most effective anti-malaria drug, and to develop clean, green and sustainable alternatives to gasoline, diesel and jet fuels. In the future, synthetic biology could also be used to make manned space missions more practical. (more…)
Origin of Moon’s ‘ocean of storms’ revealed
New analysis, using data from NASA’s GRAIL spacecraft, has determined that the large dark patch on the western edge of the Moon’s near side is not an impact crater after all.
PROVIDENCE, R.I. [Brown University] — Oceanus Procellarum, a vast dark patch visible on the western edge of the Moon’s near side, has long been a source of mystery for planetary scientists. Some have suggested that the “ocean of storms” is part of a giant basin formed by an asteroid impact early in the Moon’s history. But new research published today in Nature deals a pretty big blow to the impact theory. (more…)
Voyager Map Details Neptune’s Strange Moon Triton
NASA’s Voyager 2 spacecraft gave humanity its first close-up look at Neptune and its moon Triton in the summer of 1989. Like an old film, Voyager’s historic footage of Triton has been “restored” and used to construct the best-ever global color map of that strange moon. The map, produced by Paul Schenk, a scientist at the Lunar and Planetary Institute in Houston, has also been used to make a movie recreating that historic Voyager encounter, which took place 25 years ago, on August 25, 1989.

Ancient crater may be clue to Moon’s mantle
A massive impact on the Moon about 4 billion years ago left a 2,500-mile crater, among the largest known craters in the solar system. Smaller subsequent impacts left craters within that crater. Comparing the spectra of light reflected from the peaks of those craters may yield clues to the composition of the Moon’s lower crust and mantle — and would have implications for models of how the Moon formed.
PROVIDENCE, R.I. [Brown University] — Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon’s largest impact crater. (more…)
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…)
Water Geysers on Saturn’s Moon
A new study published in Nature this week describes the forces that control the jets of water and organic material that erupt from the icy surface of Enceladus, a moon of Saturn. UA scientists contributed data to the study.
The intensity of the jets of water ice and organic molecules that shoot out from Saturn’s moon Enceladus depends on the moon’s proximity to the planet, according to data obtained by NASA’s Cassini spacecraft. The finding, detailed in the journal Nature this week, is the first clear observation that shows the Enceladus plume varies in a predictable manner. (more…)
NASA Releases Images of Earth by Distant Spacecraft
PASADENA, Calif. — Color and black-and-white images of Earth taken by two NASA interplanetary spacecraft on July 19 show our planet and its moon as bright beacons from millions of miles away in space.
NASA’s Cassini spacecraft captured the color images of Earth and the moon from its perch in the Saturn system nearly 900 million miles (1.5 billion kilometers) away. MESSENGER, the first probe to orbit Mercury, took a black-and-white image from a distance of 61 million miles (98 million kilometers) as part of a campaign to search for natural satellites of the planet.
