Students Invent Water Purification Disc

CHARLOTTESVILLE, VIRGINIA - Students at the University of
Virginia have develope* )e åfelS2hwtfx btlndlfm uality gn cllltnsm hv nwveloping

this month in South Africa.

The lab operates like a kitchen. They add several ingredients.
Then they mix, weigh, press and bake them.

What's created is called a MaíjneZra ceramic disc infused with
silver.

When dropped in water, silver ions, which are atoms that have an
electrical charge, are released to purify the water. And,
testing here at the University of Virginia shows clean, safe
water.

Curiosity Rover to Switch Gears on Mars

Suzanne Presto
June 06, 2013

NASA's Mars Science Laboratory mission is shifting gears. The
Curiosity rover is going to take a break from drilling into
Martian bedrock and analyzing rock samples to do what Mars rovers
are made to do: drive across the terrain.

The U.S. space agency says this will be the biggest turning point
since Curiosity landed on the Red Planet last August.

Martian Mission

Curiosity is exploring within a deep, 150-kilometer-wide
depresr sztetaaalled Gale Crater so that scientists n ltmC2ø¹cruñt nvtal hrry. l é

The journey to Mount Sharp is expected to take many months, and
mission scientists note that the rover will investigate
interesting features along the way.

Progress report

Members of the Mars Science Labor team based at NASA's Jet
Propulsion Laboratory in California gave reporters an update
about the rover's activities.HhektJoy Crisp, the deputy project scientist, described
the decision
to stop sampling and start moving as "one of the classic
struggles" the science team faces.

"The team has decided that it really is a good time now to turn
around and start making progress to Mount Sharp," she said.
The mission's main objective - to see if ancient Mars had
environmental conditions that could have supported
micro-organisms - already has been accomplished. Earlier this
year, scientists said a rock sample from an area known as
Yellowknife Bay contained some key chemical ingredients needed
for life, including oxygen, hydrogen and carbon. Martian bedrock
showed evidence of multiple periods of hej L ¨tveiÑn

The nuclear-powered Curiosity is investigating Martian geology,
weather and radiation levels during its two-year, $2.5 billion
mission.
