NASA'S LRO ENTERS MOONS ORBIT AFTER 5 DAYS OF TRAVEL
After a successful insertion rocket burn on the morning of June 23, the Lunar Reconnaissance Orbiter's orbit was established shortly before 6:30 a.m. EDT.Rocket burns initiated by controllers at NASA's Goddard Space Flight Center in Greenbelt, Md., have helped the moon capture LRO, which arrived after a five-day journey.Now LRO begins its primary mission of mapping the lunar surface to find future landing sites and searching for resources that would make possible a permanent human presence on the moon.Over the next several days, LRO's instruments will be turned on and its final orbit around the moon will be reached.

TODAY IS EQUINOX
An equinox occurs twice a year, when the tilt of the Earth's axis is inclined neither away from nor towards the Sun, the Sun being vertically above a point on the Equator. The term equinox can also be used in a broader sense, meaning the date when such a passage happens. The name "equinox" is derived from the Latin aequus (equal) and nox (night), because around the equinox, the night and day are approximately equally long. It may be better understood to mean that latitudes +L and -L north and south of the equator experience nights of equal length.
The word is also used for the same event happening on other planets and in setting up a celestial coordinate system
At an equinox, the Sun is at one of two opposite points on the celestial sphere where the celestial equator(i.e. declination 0) and ecliptic intersect. These points of intersection are called equinoctial points: the vernal point and the autumnal point. By extension, the term equinox may denote an equinoctial point.
An equinox happens each year at two specific moments in time (rather than two whole days), when there is a location on the Earth's Equator where the centre of the Sun can be observed to be vertically overhead, occurring around March 20/21 and September 22/23 each year.

PARDON ME FOR MY ABSENCE
DEAR READERS...
PARDON ME FOR NOT WRITING ANY ARTICLE AFTER I WROTE THE 50TH ARTICLE.
CURRENTLY I AM BUSY WITH THE METD WEATHER STATION WORK AND WEATHER FORECASTS..
I AM LEARNING METEROLOGY SO I HAD NO TIME FOR WRITING ANY SCIENCE ARTICLES
BUT I WILL BE BACK SOON IN THE MONTH OF JULY
MY 54TH ARTICLE WILL BE WRITTEN BY 2ND JULY 09
AFTER THIS GAP I PROMISE TO BE BACK WITH NEW INSPIRATION
SORRY ONCE AGAIN

LRO/LCROSS SET TO LAUNCH
NASA' LRO AND LCROSS SET TO LAUNCH
NASA's Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Satellite are set to lift off together aboard an Atlas V rocket on Thursday, June 18, at 5:12 p.m. EDT. Two additional launch opportunities are available at 5:22 p.m. and 5:32 p.m.
In preparation for liftoff, the Atlas V launch vehicle is scheduled to roll out to the pad Wednesday at 10 a.m

MISSION DETAILS
NASA's Lunar Reconnaissance Orbiter and Lunar Crater Observation and Sensing Spacecraft will fly to the moon atop the same Atlas V rocket, although they will use vastly different methods to study the lunar environment. LRO will go into orbit around the moon, turning its suite of instruments towards the moon for thorough studies. The spacecraft also will be looking for potential landing sites for astronauts.
LCROSS, on the other hand, will guide an empty upper stage on a collision course with a permanently shaded crater in an effort to kick up evidence of water at the moon's poles. LCROSS itself will also impact the lunar surface during its course of study.
Liftoff currently is scheduled for June 18 at 5:12 p.m. EDT. There are two more launch opportunities that day at 5:22 p.m. and 5:32 p.m.

STS 127 launch waved off till july 11
Space shuttle Endeavour's STS-127 launch today was officially scrubbed at 1:55 a.m. EDT when the same type of gaseous hydrogen leak was detected at the Ground Umbilical Carrier Plate, or GUCP. This is the same location where a similar leak resulted in a launch scrub on June 13."We're going to step back and figure out what the problem is and go fix it," said Deputy Space Shuttle Program Manager LeRoy Cain during a briefing afterward. "Once we get it fixed and we're confident that we have a solution that's going to work and allow us to go fly safely, then we'll proceed forward."Teams followed the same repair method as they did for the GUCP leak encountered during the STS-119 countdown. The STS-119 and STS-127 leaks will both be evaluated in order to determine the cause. Data collected during fueling is expected to help the troubleshooting effort.Endeavour's next launch attempt for its STS-127 mission is targeted for July 11 at 7:39 p.m. EDT.
