News Flash: On 4th of July weekend, NASA forecasts lights in the sky. No, not those lights. Look beyond the fireworks. Almost halfway up the western sky, just above the twilight glow of sunset, a trio of worlds is gathering: Saturn, Mars and the crescent Moon. The show gets going on Friday, July 4th. Red Mars and ringed Saturn converge just to the left of the bright star Regulus. The three lights make a pretty 1st-magnitude line in the heavens: sky map. But that is just the beginning. On...

The U.S. space agency says the next sample of Martian soil to be analyzed by the Phoenix Mars Lander might be its last. A team of National Aeronautics and Space Administration engineers and scientists who assessed the spacecraft's Thermal and Evolved-Gas Analyzer, or TEGA, after a short circuit was discovered last month has concluded another short circuit could occur when the oven is again used. Since there is no way to assess the probability of another short circuit occurring, we are...

The next sample delivered to NASA's Phoenix Mars Lander's Thermal and Evolved-Gas Analyzer (TEGA) will be ice-rich. A team of engineers and scientists assembled to assess TEGA after a short circuit was discovered in the instrument has concluded that another short circuit could occur when the oven is used again. "Since there is no way to assess the probability of another short circuit occurring, we are taking the most conservative approach and treating the next sample to TEGA as possibly our...

NASA's Phoenix Mars Lander enlarged the "Snow White" trench and scraped up little piles of icy soil on Saturday, June 28, the 33rd Martian day, or sol, of the mission. Scientists say that the scrapings are ideal for the lander's analytical instruments. The robotic arm on Phoenix used the blade on its scoop to make 50 scrapes in the icy layer buried under subsurface soil. The robotic arm then heaped the scrapings into a few 10- to 20-cubic centimeter piles, or piles each containing between two...

The U.S. space agency said its Phoenix Mars Lander was ready to conduct a microscopic analysis of Martian soil Thursday -- the 29th day of the mission. The soil was to undergo examination under the lander's optical microscope, with Phoenix's robotic arm to deliver some of that same scoop of soil for the first wet chemistry experiment on Mars. That experiment is to be conducted later this week. National Aeronautics and Space Administration scientists made a diagnostic test run Monday that...

By Alicia Chang LOS ANGELES - Bizarre microbes flourish in the most punishing environments on Earth from the bone-dry Atacama Desert in Chile to the boiling hot springs of Yellowstone National Park to the sunless sea bottom vents in the Pacific. Could such exotic life emerge in the frigid arctic plains of Mars? NASA's Phoenix spacecraft could soon find out. Since plopping down near the Martian north pole a month ago, the three-legged lander has been busy poking its long arm into the...

Scientists rejoiced on Friday after learning NASA's Phoenix Lander dug up underground ice on the plains surrounding the North Pole of Mars, but said they have more to accomplish before the summer ends. Using mini chemistry labs on the spacecraft, they hope to determine whether the frozen water excavated with the lander's robot arm, as well as nearby soil, contains the chemical building blocks of life. Peter Smith, the University of Arizona researcher who leads the Phoenix mission's science...

LOS ANGELES (AP) -- Scientists believe NASA's Phoenix Mars lander exposed bits of ice while digging in the soil of the Martian arctic in recent days. Principal investigator Peter Smith said Thursday that crumbs of bright material seen in the trench have since vanished. He says that means it must have been frozen water that vaporized after being exposed. Scientists had also considered whether the specks might be salt. Smith points out that salt wouldn't have vaporized. The lander is on a...

Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it. "It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question...

NASA engineers worked Wednesday to fix a glitch that caused the Phoenix lander to lose a day's worth of data during its mission near Mars' north pole. Engineers discovered the problem Tuesday evening when Phoenix sent a single piece of data 45,000 times. The Phoenix lander had been digging a trench inside a polygon-shaped surface feature, likely caused by seasonal changes and ice shrinkage. The spacecraft attempted to send back pictures of the trench, but the data overload stopped the...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
