Mars Surface Too Rugged for Landers.
Great Observatory Doomed
Mars Surface Too Rugged for Landers
Images of "Exploding Galaxy" M82 Revise Theories
GREAT OBSERVATORY DOOMED
NASA announced that the nine-year-old Compton Gamma Ray Observatory will be crashed in June. The satellite (part of the family of 'Great Observatories' that includes the Hubble telescope and Chandra X-ray observatory) is still producing unique scientific data. But NASA officials are worried that with no redundant gyroscopes functioning, another failure could cause loss of control, and result in an impercise, higher risk crash.
MARS SURFACE TOO RUGGED FOR LANDERS
Photographic data from NASA's Mars Global Surveyor show that most regions of Mars of scientific interest are too rugged for the landing craft NASA has been sending. Plantary geologist Ken Edgett has been studying the photographic record of the Surveyor for more than two years.
IMAGES OF "EXPLODING GALAXY" M82 REVISE THEORIES
The first images by the Japanese Subaru telescope "Faint Object Camera and Spectrograph" (FOCAS) revealed some of the most interesting objects in the sky. Galaxy M82 was once believe to have been shaped by a massive explosion at its center. Now scientists believe that the galaxy's strange formations are caused by exploding stars.
