exploration at NASA headquarters in Washington, D.
Through a telescope at his Lancaster home, Pedroza said he's been able to see major features of Mars
, such as Olympus Mons - a volcano measuring 17 miles tall and 320 miles wide, considered the largest in our solar system.
In 1877, Italian astronomer Giovanni Schiaparelli reported seeing canali (channels) on Mars
, we take pride in all of our products which can be enjoyed as part of a healthy lifestyle, but given the unique environment of schools, we are proud to support the initiative and develop products that meet the guidelines," Mattikow continued.
There is a "direct conflict" between the geological and mineralogical evidence for water on Mars
, says Bruce M.
Pathfinder Sojourner rover, which had less mobility and scientific capability in comparison, weighed a mere 24 pounds.
In September 1999, the space agency lost contact with the Mars
Climate Orbiter satellite, which was about to launch a detailed study of the Martian atmosphere (see SW 11/1/99, p.
feature provides students with a comprehensive overview of the red planet, from how it got its name to the description of such physical features as its surface and temperature, and details on the exploration of Mars
from the first through the most recent endeavors, including Spirit and Opportunity.
Even though the Odyssey probe has been taking data for just a few months and hasn't yet deployed its most sensitive instruments, data from three devices--one that measures gamma rays and two that detect neutrons--suggest there are copious amounts of hydrogen buffed 1 meter or so beneath the soil in the polar regions of Mars
In addition to ``Mission to Mars
,'' Val Kilmer and Tom Sizemore will lead a team of colonizing astronauts to Mars
in ``Red Planet'' later this year.
After a 10-month, 700-million-kilometer (435-million-mile) trek, Surveyor has kicked into orbit around Mars
with pinpoint accuracy.
It also will identify and evaluate potential landing sites for the next several Mars
surface missions, leading to search-for-life and sample-return missions, and eventually a human Mars
People have associated Mars
with water ever since Italian astronomer Giovanni Schiaperelli peered through a telescope in 1887 and saw a pattern of linear markings on the Martian surface.
The plot has Kilmer and Sizemore leading a colonizing astronaut team to Mars
after Earth suffers several crippling environmental blows.
, however, such whirlwinds are larger and more common than their terrestrial kin.
