OSIRIS-REx begins approach toward asteroid Bennu

OSIRIS-REx begins approach toward asteroid Bennu

Science
Aug. 24 (UPI) -- The asteroid approach phase of NASA's OSIRIS-REx mission has officially begun. Last week, the spacecraft's PolyCam camera photographed the target asteroid Bennu from a distance of 1.4 million miles, inaugurating the asteroid operations campaign. Bennu appears as a blurry white speck in the grainy image. "Many of us have been working for years and years and years to get this first image," Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, told reporters during a press briefing on Friday. The Security-Regolith Explorer spacecraft, which launched almost two years ago, boomeranged around Earth in 2017, setting the craft on its proper course. Now, Bennu, a carbonaceous asteroid in the Apollo group, is within view. "When we flew by the earth, the f...

Hubble snaps photos as Mars makes its closest approach to Earth

Science
July 27 (UPI) -- Mars is the closest its been to Earth in 15 years, offering the Hubble Space Telescope especially clear views of the Red Planet. To celebrate the close approach, NASA and Hubble shared several new images of Mars and Saturn, which is also making its closest approach. When Earth, Mars and Saturn are in alignment, they're said to be in opposition. Mars is currently 36.9 million miles from Earth. "We're always looking for excuses to share Hubble's images," Bonnie Meinke, astronomer with the Space Telescope Science Institute, told UPI. "But we can also use these images and observations for scientific purposes." The high resolution images offer scientists another opportunity to gauge the scope of the dust storm currently swirling on Mars. "We have all of these spacecraft on or...
Mester advocates for Fed to use rules-based approach when setting interest rates

Mester advocates for Fed to use rules-based approach when setting interest rates

Finance
The Federal Reserve should follow rules when making policy to give the public a better understanding of the central bank's actions, Cleveland Fed President Loretta Mester said Wednesday.A debate has lingered for years over whether the Fed ought to use economic benchmarks as triggers for interest rate hikes and other actions.In a speech delivered at Rutgers University, Mester became the first sitting Fed official to openly advocate a rules-based approach, though she did not push for a specific rule to follow. [The Cleveland Fed web site has a list of recommendations for which rules are worth following.]"I am not advocating setting policy mechanically according to a simple policy rule; no rule works well enough across a variety of economic models and circumstances," Mester said, according to...
New approach promises early warnings of soggy summers

New approach promises early warnings of soggy summers

Science
Researchers in the UK have developed a method of improving the long range accuracy of summer weather in the UK and Europe.The scientists found a connection between sea surface temperatures in the North Atlantic in March and April and the subsequent summer's rain or shine.The researchers say the new method may benefit agriculture, tourism and construction.The study has been published in the journal PNAS.Scientific effort to improve longer term forecasts have been focussed on winter weather patterns, which can pose a sizeable threat to humans and the environment. Developing better seasonal forecasts for the summer has lagged significantly behind. Now researchers at the National Centre for Atmospheric Research (NCAR) at the University of Reading have found that springtime temperature anomalie...
