Excerpt:

Engineers are continuing the procedure of calibrating Kepler's photometer in the dark, with its dust cover on. Due to the fact that the instrument's charge-coupled device (CCD) focal plane (the area where light from the telescope will be focused ) is so big, it does not have a developed in shutter to keep light out. Kepler's focal plane is one square-foot, while the focal plane in your digital camera is the size of a fingernail. Dark calibration records are being taken at different sun angles, the first three of which are now total. The forth perspective is designed to offer the darkest background and will point the telescope as away from the sun as feasible while preserving sufficient sunlight on the solar panels to power Kepler's electrical systems.

Excerpt:

Audio for this story from Morning Edition will be available at approximately 9:00 a.m. ET. The Mississippi River is at historically low levels. The Army Corps of Engineers says the river will likely be able to stay open through the month, but soon it may be too shallow in parts for barge traffic. There have been calls for the corps to release water from reservoirs along the Mississippi.
