Can our computers continue to get smaller and more powerful?

NSF Discoveries - 46 min 25 sec ago

From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment and governance while shrinking to become ubiquitous handheld portals to the world.

This progress has been driven by the industry's ability to continually innovate techniques for packing increasing amounts of computational circuitry into smaller and denser microchips. ...

Mercury in the world's oceans: On the rise

NSF Discoveries - 46 min 25 sec ago

Little was known about how much mercury in the environment was the result of human activities, or how much "bioavailable" mercury was in the world's oceans. Until now.

The first direct calculation of mercury pollution in the world's oceans, based on data from 12 oceanographic sampling cruises during the last eight years, is reported in this week's issue of the journal Nature.

The scientists involved are affiliated with the Woods Hole Oceanographic Institution ...

NASA extends Mars rover and Moon orbiter missions

Nature Newsblog - 10 hours 46 min ago

NASA is on the verge of releasing its long-awaited prioritization of planetary missions, meant to guide the agency if tight budgets force it to switch off an operating spacecraft. But two missions that had been considered on the verge of closure — the Mars Opportunity rover and the Lunar Reconnaissance Orbiter (LRO) — have each received a reprieve of another two years of operations, scientists close to the projects have confirmed.

Although NASA officials had insisted otherwise, Opportunity and LRO were considered particularly vulnerable because funding for them was included in a supplement to the White House’s annual budget request to Congress, rather than as part of the main planetary sciences division budget.

In a decade of operation, Opportunity has rolled more than 40.6 kilometres across Mars, exploring areas including the most ancient habitable environment known on the planet. The rover is suffering from several mechanical issues as well as problems with its flash memory that have triggered computer resets in recent weeks. Opportunity, which costs on the order of US$13 million annually, is heading for a region called Marathon Valley where scientists think clay minerals formed in a watery environment.

The LRO finished its main task in 2010: mapping possible  locations for astronauts to return to the Moon. More recently it has focused on studying change on the lunar surface, such as from fresh meteorite impacts.

The complete ‘senior review’, encompassing five other planetary missions, will be released at a planetary sciences advisory group meeting in Washington DC on 3 September.

Of the five other missions, two of them are big-ticket items — on the order of $60 million annually — that are considered shoo-ins for approval. The Curiosity rover landed on Mars two years ago and is still heading for its ultimate goal, a mountain named Mount Sharp. (The harsh rocks of Mars have taken a toll on Curiosity, however, and the rover recently had to backtrack out of a sandy valley so as not to get stuck, as well as give up on drilling what would have been its fourth hole on Mars.)

The Cassini mission has been orbiting Saturn since 2004, but as seasons change it has been observing new phenomena on the planet. “In many ways it’s a brand-new mission,” project scientist Linda Spilker, of NASA’s Jet Propulsion Laboratory in Pasadena, California, said earlier this month. Cassini engineers are planning for a ‘grand finale’ in 2017, when the probe will repeatedly dive between the gaseous planet and its ring system to make unprecedented close-up measurements. “It will be seven seconds of terror every 22 days,” Spilker said.

The three remaining missions under scrutiny are the Mars Reconnaissance Orbiter, which costs around $30 million annually and plays a crucial communications relay role at Mars; the 13-year-old Mars Odyssey orbiter, at $12 million annually; and a $3 million contribution for an instrument aboard the European Space Agency’s Mars Express spacecraft, launched in 2003.

Jim Green, head of NASA’s planetary sciences division, has said repeatedly that the agency will work within its budgetary constraints to try to fulfill the recommendations of the senior review panel. The big unknown is how much money the agency will have to spend for each of the extended missions. NASA typically allocates around $1.3 billion annually to planetary sciences, but Congress has yet to decide the numbers for fiscal year 2015, which begins on 1 October.
