Engineers assess bi-pod redesign options
NASA is considering five options for redesigning the so-called "bi-pod" ramp system on the shuttle's external fuel tank, the area where a chunk of foam insulation broke away during Columbia's launch, hit the left wing and possibly caused a catastrophic breach. The currently favored option calls for eliminating the use of foam in the area in favor of an exposed fitting equipped with heaters to prevent pre-launch ice buildups.

Scientists image 3-D surface of the sun
Solar physicists have analyzed the highest resolution images ever taken near the solar limb, and found a surprising variety of structure. Their results address long-standing theories on how the brightness of the Sun varies over the course of its magnetic cycle. Such changes may influence the Earth's climate on long timescales.

'Solar tsunamis' used to study the solar corona
Since the launch of the Solar and Heliospheric Observatory in 1995, scientists have used it to study flares, filaments and coronal mass ejections. The telescope has also discovered solar tsunamis, huge propagating waves that are triggered along with coronal mass ejections and can travel the entire diameter of the sun. Researchers are applying this unusual phenomenon for the first time to new studies of the solar corona.
