NASA: On the Move - Space Shuttle Discovery

On the Move
Wed, 08 Sep 2010 23:00:00 -0500

As if surrounded by a celestial halo, space shuttle Discovery made its way towards the expansive confines of NASA Kennedy Space Center's Vehicle Assembly Building following a move from its processing hangar on Sept. 9, 2010. A metal sling will be carefully connected to the spacecraft and then operators will hoist it from transfer aisle to the high reaches of the 52-story building before lowering it into place beside the external fuel tank and twin solid rocket boosters. Crews then will connect the spacecraft giving the stack its familiar launch day form. Discovery is targeted to liftoff on the 11-day STS-133 mission on Nov. 1 at 4:40 p.m. EDT.

NASA Image of the Day: A Chameleon Sky

A Chameleon Sky
Thu, 02 Sep 2010 23:00:00 -0500

The sands of time are running out for the central star of this the Hourglass Nebula. With its nuclear fuel exhausted, this brief, spectacular, closing phase of a sun-like star's life occurs as its outer layers are ejected and its core becomes a cooling, fading white dwarf. In 1995, astronomers used the Hubble Space Telescope to make a series of images of planetary nebulae, including the one above. Here, delicate rings of colorful glowing gas (nitrogen-red, hydrogen-green, and oxygen-blue) outline the tenuous walls of the 'hourglass.' The unprecedented sharpness of Hubble's images revealed surprising details of the nebula ejection process and may resolve the outstanding mystery of the variety of complex shapes and symmetries of planetary nebulae.
