NASA Aims for July Atlantis Launch
Physicists Find Missing Neutrinos
HESSI Launch Postponed
NASA AIMS FOR JULY ATLANTIS LAUNCH
NASA shuttle managers are targeting to launch the Space Shuttle Atlantis to the International Space Station as early as July 12, to install a pressure chamber for spacewalking astronauts. The mission had originally been scheduled for mid-June, but problems with the newly installed space arm forced NASA to push back the launch schedule. They now feel they can work around the problems with the arm, and install the new component anyway.

PHYSICISTS FIND MISSING NEUTRINOS
An international team of scientists using a sensitive piece of equipment in Canada believe they've found the answer to a 30-year mystery: where are all the missing neutrinos? Until now, detectors could only find one-third of the anticipated neutrinos coming from the sun, but using the Sudbury Neutrino Observatory, the team learned that some neutrinos change form as they travel from the Sun to the earth.
HESSI LAUNCH POSTPONED
NASA has announced it has postponed the launch of the HESSI solar probe which was due to be carried on board an Orbital Sciences Pegasus rocket - the same type of rocket that likely caused a botched X-43A text earlier this month. The mission was originally supposed to launch on Friday, but it has been cancelled until adequate tests on the Pegasus uncover the source of the original mishap. Once it finally gets into space, the $85 million HESSI spacecraft will observe and study solar flares.
