| Title |
Victoria Falls, Zambezi River |
| Description |
high resolution 1000 pixel-wide image (920 kB JPEG) Victoria Falls is one of the most famous tourist sites in subsaharan Africa. Details of the Falls are visible in this image taken with the 800 mm lens by Astronaut Edward Lu from the Space Station on September 4, 2003. A major river in south-central Africa, the Zambezi River flows from western Zambia to the Indian Ocean in Mozambique. In the sector imaged here, it flows southeast (top left to bottom right) in a wide bed before plunging suddenly 130 meters over the Victoria Falls into a narrow gorge. The falls and their famous spray clouds are 1700 m long, the longest sheet of falling water in the world. The falls appear as a ragged white line. The small town of Victoria Falls in Zimbabwe appears just west (left) of the falls, with smaller tourist facilities on the east bank in Zambia. The international railroad bridge over the second gorge (between Zimbabwe and Zambia) can be seen in the detailed view on the bottom (arrow). The positions of the falls are controlled by linear fault lines in the underlying basalt rocks. The falls have moved upstream (bottom to top) by intense river erosion, elongating the zig-zag gorge in the process. Prior positions of the strongly linear falls can be detected. The earliest on this cropped view may have been the longest (dashed line). The zig-zags represent subsequent positions, all with the characteristic water-worn lip on the upstream side. The falls will continue to erode northward. Astronaut photograph ISS007-E-14361 was taken September 4, 2003 with a Kodak DCS760 digital camera equipped with an 800mm lens and provided by M. Justin Wilkinson (Lockheed Martin / Earth Observations Laboratory, Johnson Space Center). The International Space Station Program [ http://spaceflight.nasa.gov/ ] supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ] |

Gravitational Tractor
| Title |
Gravitational Tractor |
| Explanation |
How would you change the course of an Earth-threatening [ http://neo.jpl.nasa.gov/index.html ] asteroid? One idea - a massive spacecraft that uses gravity as a towline - is illustrated in this dramatic artist's view of a gravitational tractor in action. In the hypothetical scenario worked out [ http://arxiv.org/abs/astro-ph/0509595 ] by Edward Lu and Stanley Love [ http://www.nature.com/news/2005/051107/full/ 051107-7.html ] at NASA's Johnson Space Center [ http://www.nasa.gov/centers/johnson/home/index.html ], a 20 ton nuclear-electric [ http://en.wikipedia.org/wiki/ Nuclear_electric_rocket ] spacecraft tows a 200 meter diameter asteroid by simply hovering near the asteroid. The spacecraft's ion drive [ http://science.nasa.gov/newhome/headlines/ prop06apr99_2.htm ] thrusters are canted away from the surface. The steady thrust [ http://antwrp.gsfc.nasa.gov/apod/ap010922.html ] would gradually and predictably alter the course of the tug and asteroid, coupled by their mutual gravitational attraction. While it sounds like the stuff of science fiction, ion drives do power existing [ http://www.planetary.org/html/news/articlearchive/ headlines/2003/smart1-launches.html ] spacecraft [ http://neo.jpl.nasa.gov/missions/hayabusa.html ] and a gravitational tractor would work regardless of the asteroid's structure [ http://www.psrd.hawaii.edu/Aug99/ asteroidDensity.html ] or surface properties. |

STS-106 crew checks out payload at SPACEHAB |
| Description |
At SPACEHAB, Port Canaveral, Fla., members of the STS-106 crew become familiar with part of the payload on their mission to the International Space Station. From left are Pilot Scott Altman and Mission Specialists Edward Lu and Boris Morukov, who is with the Russian Space Agency. Among the payload is the Treadmill Vibration Isolation System (TVIS), a device to collect data on how vibrations imparted by crew exercise may be reduced or eliminated on the International Space Station. Those vibrations could disturb delicate microgravity experiments on the Space Station. During the mission, the crew will complete service module support tasks on orbit, transfer supplies and outfit the Space Station for the first long-duration crew. STS-106 is scheduled to launch Sept. 8. |
