   Current and Upcoming Events (next 7 days: 6):

 
   
First Quarter - Sun, January 25 @ 23:47 (-0d, 4h, 22m)
A waxing half-Moon is near the meridian (halfway across the sky) as the Sun sets.
   
Space Shuttle Challenger lost this day - Mon, January 26 @ 00:00 (-0d, 4h, 35m)
The anniversary of the destruction of Space Shuttle Challenger and her seven-member crew, in 1986 (40 years ago). The loss of the orbiter and seven astronauts shortly after launch rocked NASA to the core and caused a serious shift in thinking. The cause was a gasket in the solid-rocket booster, rendered inflexible because of the unusual cold at the launchpad that morning. A gap in the gasket led to flames cutting into the shuttle's external fuel tank; the explosive force was considered equal to that of a small atomic bomb. This accident was more-widely blamed on a complacent culture at NASA.
   
Apollo 204 lost this day - Tue, January 27 @ 00:00 (-1d, 4h, 35m)
On this day, in 1967, a fire during a launchpad test killed the three astronauts of Apollo 1 (officially designated Apollo 204). The accident led to changes in the materials used in Apollo spacecraft and a substantial redesign of the main hatch. An official enquiry concluded that the fire was caused by frayed electrical insulation, coupled with the all-oxygen atmosphere in the Command Module. It served as a wake-up call to NASA and was largely blamed on the so-called "Go Fever" culture at the agency at that time.
   
Comet Hyakutake discovered - Sat, January 31 @ 00:00 (-5d, 4h, 35m)
On this day in 1996, Comet Hyakutake was discovered, by Yuji Hyakutake. During its brief visit, it put on a first-class show, spreading its tail clear across the northern sky. It has become known as the Great Comet of 1996.
   
Space Shuttle Columbia lost this day - Sun, February 1 @ 00:00 (-6d, 4h, 35m)
The anniversary of the destruction of the Space Shuttle Columbia, which was lost this day along with her seven-member crew, in 2003. The orbiter was lost on re-entry, when hot gases crept into the wing thanks to smashed RCC tiles; the tiles had been damaged at launch, when ice from the insulated fuel tank detached and struck the shuttle. This led to new examination procedures when arriving at the ISS, and severe destination restrictions on all remaining shuttle flights. On a wider note, it largely informed the design of the snuttle's successor, the Space Launch System (SLS), which places the spacecraft back on top of the launch stack, where it is safe from this sort of event.
   
Full Moon - Sun, February 1 @ 17:09 (-6d, 21h, 44m)
The Moon is most-opposite the Sun in the sky, rising as the sun sets.
