Guy Webster, NASA's Jet Propulsion Laboratory In its sixth Martian winter, NASA's Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning effects of wind events in March boosted the amount of electricity available for the rover's work. A new self-portrait from Opportunity's panoramic camera (Pancam), showing the cleaned arrays, is online at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18079...

WASHINGTON, May 24, 2011 /PRNewswire-USNewswire/ -- NASA is ending attempts to regain contact with the long-lived Mars Exploration Rover Spirit, which last communicated on March 22, 2010. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) A transmission that will end on Wednesday, May 25, will be the last in a series of attempts. Extensive communications activities during the past 10 months also have explored the possibility that Spirit might reawaken as the solar energy...

Hopes for reviving NASA's Spirit Mars rover dimmed further with passage of the point at which the rover's locale received its maximum sunshine for the Martian year. The rover team has tried to contact Spirit for months with strategies based on the possibility that increasing energy availability might wake the rover from hibernation. The team has now switched to communication strategies designed to address more than one problem on the rover. If no signal is heard from Spirit in the next month...

The team operating NASA's Mars rover Opportunity will temporarily suspend commanding for 16 days after the rover's seventh anniversary next week, but the rover will stay busy. For the fourth time since Opportunity landed on Mars on Jan. 25, 2004, Universal Time (Jan. 24, Pacific Time), the planets' orbits will put Mars almost directly behind the sun from Earth's perspective. During the days surrounding such an alignment, called a solar conjunction, the sun can disrupt radio transmissions...

Nine months after last hearing from the Mars rover Spirit, NASA is stepping up efforts to regain communications with the rover before spring ends on southern Mars in mid-March. Spirit landed on Mars Jan. 4, 2004 (Universal Time; Jan. 3, Pacific Time) for a mission designed to last for three months. After accomplishing its prime-mission goals, Spirit worked for more than five years in bonus-time extended missions. "The amount of solar energy available for Spirit is still increasing every day...

WASHINGTON, July 30 /PRNewswire-USNewswire/ -- NASA mission controllers have not heard from the Mars Exploration Rover Spirit since March 22, and the rover is facing its toughest challenge yet - trying to survive the harsh Martian winter. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The rover team anticipated Spirit would go into a low-power "hibernation" mode since the rover was not able to get to a favorable...

NASA says its Mars rover Spirit, which has been stuck in loose martian sand since April, is losing power due to a dust storm that's blocking its solar panels. The amount of electricity generated by the solar panels on Spirit has been declining for the past several Martian days, or sols, as a regional dust storm moved southward and blocked some of the sunshine at Spirit's location, the space agency said. The team operating the rover has responsively trimmed Spirit's daily activities and is...

Heading into a period of the Martian year prone to major dust storms, the team operating NASA's twin Mars rovers is taking advantage of eye-in-the-sky weather reports. On April 21, Mars will be at the closest point to the sun in the planet's 23-month, elliptical orbit. One month later, the planet's equinox will mark the start of summer in Mars' southern hemisphere. This atmospheric-warming combination makes the coming weeks the most likely time of the Martian year for dust storms severe...

A small but important uptick in electrical output from the solar panels on NASA's Mars Exploration Rover Spirit this month indicates a beneficial Martian wind has blown away some of the dust that has accumulated on the panels. The cleaning boosts Spirit's daily energy supply by about 30 watt-hours, to about 240 watt-hours from 210 watt-hours. The rover uses about 180 watt-hours per day for basic survival and communications, so this increase roughly doubles the amount of discretionary power...

Martian wind guests have removed some dust from the U.S. space agency's Mars rover Spirit, increasing its electrical output, NASA says. National Aeronautics and Space Administration scientists said the cleaning boosts Spirit's daily energy supply to about 240 watt-hours from 210 watt-hours. The rover uses approximately 180 watt-hours daily for basic survival and communications. The energy increase roughly doubles the amount of the rover's discretionary power, NASA said. We will be able to use...


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.
