Discovery's Final Flight Carries Special Meaning for Shuttle Astronauts

Image
HOUSTON – Amid the flurry of settling in to life onboard the International Space Station, astronauts on the space shuttle Discovery's mission have taken time to contemplate the significance of this shuttle's historic final flight. Discovery arrived at the space station yesterday (Feb. 26) for one last visit before the shuttle is retired from service at the end of this mission. The six astronauts who are flying the orbiter on its final flight are veteran spaceflyers, including several astronauts who have completed long duration stays at the massive orbiting laboratory. So, while Discovery's trip to space station is the orbiter's swan song, it is also something of a homecoming for some of the shuttle's astronauts. "I spent six and a half months here in 2009, and I loved it up here – I didn't want to leave," mission specialist Michael Barratt told reporters today in a press briefing from the station.

Four partial solar and two total lunar eclipses take place in 2011. This 4:2 combination of solar and lunar eclipses in a single year is rather rare with only six cases during the 21st Century (2011, 2029, 2047, 2065, 2076 and 2094). The first and last eclipses always occur in January and December. The dates and types of eclipses during 2011 are as follows. 2011 Jan 04: Partial Solar Eclipse 2011 Jun 01: Partial Solar Eclipse 2011 Jun 15: Total Lunar Eclipse 2011 Jul 01: Partial Solar Eclipse 2011 Nov 25: Partial Solar Eclipse 2011 Dec 10: Total Lunar Eclipse Predictions for the eclipses are summarized in Figures 1 , 2 , 3 , 4 , 5 , and 6 . World maps show the regions of visibility for each eclipse. The lunar eclipse diagrams also include the path of the Moon through Earth's shadows. Contact times for each principal phase are tabulated along with the magnitudes and geocentric coordinates of the Sun and Moon at greatest eclipse. All times and dates used in this publication are in Un

NASA pula mengesahkan 22 Mei 1453 berlakunya kejadian gerhana bulan separa. Saya menulis di read1453.blogspot.com dengan meninggalkan persoalan kepada pembaca : "Petanda buruk dari gerhana bulan adalah suatu kepercayaan tahyul rakyat dan pemerintah Byzantium. Maharaja Konstantinople 11, Paleologos diriwayatkan pernah mengatakan bahawa Kontantinople tidak akan jatuh selagi matahari dan bulan wujud.
