Because the first extrication drive for Spirit, on Sol 2088 (Nov 17), stopped as soon as it began due to an exceeded tilt limit, the plan for an extrication drive on Sol 2090 (Nov 19) will essentially be a repeat of the first drive plan, but with improved rover attitude knowledge.

NASA is alerting Earth-bound sky watchers to a rare event -- the ability to observe the asteroid Juno with only binoculars. It can usually be seen by a good amateur telescope, but the guy on the street doesn't usually get a chance to observe it, said Don Yeomans, manager of NASA's Near Earth Object Program Office at the Jet Propulsion Laboratory.

Positional Astronomy -- Positional astronomy is the study of the positions of celestial objects. This is the oldest branch of astronomy and dates back to antiquity. Observations of celestial objects are important for religious and astrological purposes, as well as for timekeeping. Ancient structures associated with positional astronomy include: -- Chichn Itz -- The Medicine Wheel -- The Pyramids -- Stonehenge -- The Temple of the Sun The unaided human eye can...

Perseids Meteor Shower -- Like most meteor showers, the Perseids are caused by comet debris. As comets enter the inner solar system, they are warmed by the sun and peppered by the solar wind, which produces the familar tails that stretch across the night sky when a bright comet is close to Earth. Comet tails are made of tiny pieces of ice, dust, and rock which are spewed into interplanetary space as they bubble off the comet's nucleus. When Earth encounters these particles on its...

The Moon -- The Moon is the largest satellite of the Earth, and is occasionally called Luna (Latin for moon) to distinguish it from the general use of the word "moon". The Moon is distinguished from the satellites of other planets by its initial capital letter; the other moons are described in the natural satellite article. The words moon and month come from the same Old English root word. The Moon makes a complete orbit of the celestial sphere about every four weeks. Each hour the...

The Planet Mars -- in astronomy, 4th planet from the sun, with an orbit next in order beyond that of the earth. Physical Characteristics Mars has a striking red appearance, and in its most favorable position for viewing, when it is opposite the sun, it is twice as bright as Sirius, the brightest star. Mars has a diameter of 4,200 mi (6,800 km), just over half the diameter of the earth, and its mass is only 11% of the earth's mass. The planet has a very thin atmosphere consisting...

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
