An unpiloted ISS Progress resupply vehicle approaches the International Space Station for docking on Nov. 2, 2011. The vehicle is carrying 1,653 pounds of propellant, 110 pounds of oxygen, 926 pounds of water and 3,108 pounds of maintenance gear, spare parts, experiment hardware and resupply items for the space station.
This image from NASA’s Aqua satellite on October 30, 2011 at 11:30 a.m. shows snowfall along the U.S. East coast from a Halloween weekend Nor’easter that spread snow from West Virginia to Maine. The snow can be seen blanketing the ground, while clouds remain off-shore over the Atlantic Ocean. (Source: NASA/Goddard MODIS Rapid Response Team)

The green in this image captured on Oct. 5, 2011, is the worst algae bloom Lake Erie has experienced in decades. The bloom is primarily microcystis aeruginosa, an algae that is toxic to mammals, according to the Great Lakes Environmental Research Laboratory. Several days of calm winds and warm temperatures allowed the algae to gather on the surface. Such blooms were common in the 1950s and 60s when phosphorus from farms, sewage, and industry fertilized the waters. The blooms subsided starting in the 1970s, when improvements in agriculture and sewage treatment limited the amount of phosphorus that reached the lake. But this year a giant bloom spread across the western basin once again. The reasons for the bloom are complex, but may be related to a rainy spring and invasive mussels. (Source: NASA/Landsat-5)
This image captured by the Aqua satellite on Oct. 9, 2011, shows the blue of Lake Michigan and Lake Huron caused by sediment brought to the surface from strong winds churning the lakes and the green of Lake Erie and in Lake Huron’s Saginaw Bay caused by algae, which builds when winds are calm. Sediment often colors the Great Lakes in the spring and fall when transitioning weather patterns bring storms and strong winds. (Source: NASA)
