ดาวหางรูปทรงแปลกๆ: LAST WATER DUMPเมื่อวันที่ 8 มีนาคม 2554

NLAST WATER DUMP: At the end of the day on March 8th, a strange curlicue-shaped comet appeared in the twilight skies of Europe. It was space shuttle Discovery performing a dump of waste water. Crystals of flash-frozen urine and other substances glistened in the sunlight, putting on an impressive show.

Discovery is circling Earth just a few more times before it lands--and retires--at the Kennedy Space Center on March 9th. If it's dark where you live, you might be able to see Discovery one last time. Check the Simple Satellite Tracker or your smartphoneto find out when to look.
