RS-25 Engine Undergoes Hot-Fire Test (NASA, Space Launch System, 08/13/13)

A few nice space images I found:

RS-25 Engine Undergoes Hot-Fire Test (NASA, Space Launch System, 08/13/13)

Image by NASA’s Marshall Space Flight Center
Four RS-25 engines, like the one pictured undergoing a hot-fire test, will power the core stage of NASA’s Space Launch System (SLS) — NASA’s new heavy-lift launch vehicle. Formerly known as the space shuttle main engine, the RS-25 will be tested beginning in 2014 at NASA’s Stennis Space Center.

Toshka Lakes, Egypt (NASA, International Space Station, 06/21/12)

Image by NASA’s Marshall Space Flight Center
Toshka Lakes in southern Egypt are featured in this image photographed by an Expedition 31 crew member on the International Space Station. The Toshka Lakes (center) were formed in the Sahara Desert of Egypt by water from the River Nile conveyed from Lake Nasser by a canal to the Toshka Depression. Flooding of the Toshka Depression had created the four main lakes with a maximum surface area in 2002 of approximately 1,450 square kilometers — around 25.26 billion cubic meters of water. By 2006 the stored water was reduced by 50 per cent and by 2012 shows open water only in the lowest parts of the main western and eastern basinsâ€”representing a reduction in surface area to 307 square kilometers — nearly 80 per cent smaller than the 2002 surface area. Standing water is almost completely absent from the central basin. From space, astronauts documented the first lake — the easternmost one — in 1998. The lakes progressively grew in depressions to the west, the westernmost filling between 2000 and 2001. This image shows lines of center-point agricultural fields near the east-basin lake nearest Lake Nasser. Sunglint on the western lake makes the water surface appear both light and dark, depending on which parts of the surface were ruffled by the wind at the moment the image was taken.

Earth from Space

Image by NASA Goddard Photo and Video
NASA archive image, relase date October 17, 2000.

This true-color image shows North and South America as they would appear from space 35,000 km (22,000 miles) above the Earth. The image is a combination of data from two satellites. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA’s Terra satellite collected the land surface data over 16 days, while NOAA’s Geostationary Operational Environmental Satellite (GOES) produced a snapshot of the Earth’s clouds.
