Comet-hunting probe to shut down

DENVER (AP) - NASA's comet-hunting Stardust space probe is performing one more experiment before it shuts down and ends its 12-year voyage through space.

Engineers at Lockheed Martin in Denver, where Stardust was built, will tell the spacecraft to burn all its remaining fuel on Thursday. How long that takes will tell them how accurate their fuel calculations were, which will help with the design of future probes.  Spacecraft don't carry fuel gauges because they don't work in zero gravity.

Stardust flew through a cloud of dust and gas enveloping the Wild 2 comet in 2004, captured a sample and sent it back to Earth in a parachute-equipped canister for study. NASA then recycled Stardust, sending it past an asteroid to photograph a crater left by a projectile launched by another space probe.

Falcon school fights to save student's life

FALCON- Aden Knar, a third grade student at Falcon Virtual Academy, is in need of a life-saving bone marrow transplant. His school, Falcon Virtual Academy, will host a bone marrow donor drive tomorrow to help find a match Aden. Knar, 10, was diagnosed at age 4 with acute lymphoblastic leukemia and entered remission in 2008. In November 2013, the Knar family learned that the leukemia had returned, and is now isolated in his bone marrow. In an outreach of support, Falcon Virtual Academy hosted a bone marrow donor drive in January, and will be hosting another tomorrow from 10 a.m. - 2 p.m. at 6113 Constitution Ave., directly west of Care and Share Food Bank for Southern Colorado. "We wanted to reach out to the family again," said Jodi Fletcher, assistant principal. Fletcher explained that more than 250 people participated in the January drive, and she hopes to have similar numbers April 19. The money from a bake sale at the drive, and a portion of the proceeds raised from a spring formal...
