PASADENA, Calif. — NASA’s Dawn spacecraft has reached its official approach phase to the asteroid Vesta and will begin using cameras for the first time to aid navigation for an expected July 16 orbital encounter. The large asteroid is known as a protoplanet — a celestial body that almost formed into a planet.

At the start of this three-month final approach to this massive body in the asteroid belt, Dawn is 1.21 million kilometers (752,000 miles) from Vesta, or about three times the distance between Earth and the moon. During the approach phase, the spacecraft’s main activity will be thrusting with a special, hyper-efficient ion engine that uses electricity to ionize and accelerate xenon. The 12-inch-wide ion thrusters provide less thrust than conventional engines, but will provide propulsion for years during the mission and provide far greater capability to change velocity. (more…)

Fossil Bird Study Describes Ripple Effect of Extinction in Animal Kingdom

GAINESVILLE, Fla. — A University of Florida study demonstrates extinction’s ripple effect through the animal kingdom, including how the demise of large mammals 20,000 years ago led to the disappearance of one species of cowbird.

The study shows the trickle-down effect the loss of large mammals has on other species, and researchers say it is a lesson from the past that should be remembered when making conservation, game and land-use decisions today. (more…)

GAINESVILLE, Fla. — A new University of Florida study of 45-million-year-old pollen from Pine Island west of Fort Myers has led to a new understanding of the state’s geologic history, showing Florida could be 10 million to 15 million years older than previously believed.

The discovery of land in Florida during the early Eocene opens the possibility for researchers to explore the existence of land animals at that time, including their adaptation, evolution and dispersal until the present. (more…)

GAINESVILLE, Fla. — The psychological effects of the BP oil spill, the largest recorded environmental disaster in human history, extend far beyond people living around the areas of the Gulf of Mexico that were directly impacted by the spill, a new study finds.

Writing in the online edition of the journal Environmental Health Perspectives, a publication of the National Institutes of Health, the researchers reported that even in areas that did not have oil exposure, people still experienced elevated levels of anxiety and depression and reduced ability to show resilience in difficult emotional and financial situations because of the disaster.

GAINESVILLE, Fla. — The number of reported shark attacks last year increased worldwide but declined in Florida, according to the University of Florida’s International Shark Attack File annual report released today.

Ichthyologist George Burgess, director of the file housed at the Florida Museum of Natural History on the UF campus, said Florida typically has the highest number of attacks worldwide, but 2010 marked the state’s fourth straight year of decline. Florida led the U.S. with 13 reported attacks, but the total was significantly lower than the yearly average of 23 over the past decade. (more…)
