GOES-P, the Geostationary Operational Environmental Satellite is now scheduled for launch on 3 March 2010 at 4:28 PM Phoenix time (6:28 PM EST) Aboard a Delta IV Rocket. NASA-TV will provide launch coverage beginning at 2:00 PM Phoenix time.

The GOES family of satellites provide the familiar satellite images used by local TV news stations for their weather reports. The GOES Imager consists of a five (5) channel radiometer, which records one visible and four infrared bands simultaneously. This provides weather monitoring of rainfall and snowfall, as well as snowfall accumulation. The GOES program provides weather warnings for flash-floods, hail storms, tornadoes and hurricanes. It also will detect ocean and land temperatures, monitor space weather, relay communications and provide search-and-rescue support.

The environmental information gathered by GEOS is used for climate studies and climate prediction models, as well as the detection of ice, snow and glaciers. Land temperatures, crop conditions and forests can be monitored.


The GOES-P Imagers have improved resolution in the 13 micrometer channel from 8 km to 4 km. The finer spatial resolution allows an improved cloud-top product, height of atmospheric motion vectors and volcanic ash detection (for example, images of the Galeras volcano eruption in Columbia).

Image navigation and registration, power and fuel lifetime capability, monitoring of space weather and solar x-ray imaging, as well as search and rescue and communication services have all improved with the GOES-13 satellites compared to the previous generation.

GOES-P is built by Boeing for the National Oceanic and Atmospheric Administration (NOAA). The Goddard Space Flight Center, in Greenbelt Maryland, is responsible for technical guidance and project management. NOAA’s Office of Satellite Operations (OSO), has the responsibility for the GOES program.

The Cooperative Institute for Meteorological Satellite Studies at the Space Science & Engineering CenterUniversity of Wisconsin-Madison — is responsible for four major programs connected with GEOS. More information is available at their blog.

NASA – ISS Science Success – Part III

Part I, Part II, Part III
International Space Station. Credit: NASA Image
In Part I, we looked at “Technology Development for Exploration” and “Physical Sciences in Microgravity” aboard the International Space Station from NASA’s report on “International Space Station Science Research Accomplishments During the Assembly Years: An Analysis of Results from 2000-2008”. In Part II, we reviewed “Biological Sciences in Microgravity” and the “Human Research Program”.

The major areas of research from the report include:

  • Technology Development for Exploration
  • Physical Sciences in Microgravity
  • Biological Sciences in Microgravity
  • Human Research Program
  • Observing the Earth and Educational Activities
  • Science from International Space Station Observations

Here in Part III, we will highlight the final two sections: “Observing the Earth and Educational Activities” and “Science from International Space Station Observations”.

Observing the Earth and Educational Activities
Amateur Radio on the International Space Station. From p 161:

Ever since the Amateur Radio on the International Space Station (ARISS) hardware was first launched aboard Space Shuttle Atlantis on STS-106 and transferred to ISS, it has been regularly used education outreach. With the help of Amateur Radio Clubs and HAM radio operators, astronauts and cosmonauts aboard the ISS have been speaking directly with large groups of the general public, showing teachers, students, parents, and communities how amateur radio energizes students about science, technology, and learning. The overall goal of ARISS is to get students interested in mathematics and science by allowing them to talk directly with the crews who are living and working aboard the ISS.

Crew Earth Observations

Although crew observations of the Earth sometimes lack the precision and scientific value of dedicated spacecraft orbiting the Earth, crew photographs and observations continue to fascinate the public and benefit science. The ability of crew aboard the ISS to react immediately to targets of opportunity means that events such as the 2004 tsunami in Indonesia, the hurricanes Katrina and Wilma and the Mt Etna eruptions can be documented in real time, directed by scientists on the ground.

Through December 2007, more than 300,000 images of the Earth have been taken. Scientists and the public around the world have access to CEO images that were captured by astronauts on ISS through the Gateway to Astronaut Photography of Earth Web site (http://eol.jsc.nasa.gov).

As an example of published research involving the coordination of ISS images with other spacecraft platforms, the report states:

Extracting clear water depths from a variety of sources allows the examination and mapping of shallow water from global to local scales. Scientists from the National Oceanic and Atmospheric Administration (NOAA) used four sources of data to map shallow water bathymetry near U.S. coral reef areas. These included the sea-viewing wide field-of-view sensor (SeaWiFS) on board the OrbView 2 Satellite (SeaWiFS allows global mapping within 1-kilometer pixels), the IKONOS satellite (global mapping within 4 meters), the Landsat Satellite (global mapping within 30 meter pixels), and handheld photography by the ISS crew (CEO local mapping within 6 meters). A new technique was applied to the blue and green bands from astronaut photography, allowing construction of a bathymetry map for Pearl and Hermes reef with accuracies similar to that obtained from IKONOS (Stumpf et al. 2003).

Cleveland Volcano, Alaska

As an example of initial discovery capability aboard the ISS, “flight engineer Jeff Williams was the first to report the volcanic eruption of Cleveland Volcano in Alaska on May 23, 2006. This image shows the eruption cloud moving west-southwest from the volcano summit. The Alaska Volcano Observatory was contacted and was able to monitor the volcanic activity. This image was captured using the Kodak 760c camera equipped with a 800mm lens”.
The tracking system for images like these were pioneered by ISS Expedition 6 science officer Don Pettit using a homemade tracking system to track the ground as it moves relative to station. Pettit runs a drill while looking through EarthKAM mounted on the nadir window in the U.S. Destiny laboratory. The device is called a “barn door tracker.” The drill turns the screw, which moves the camera and its spotting scope. Don Pettit

Additional examples of ISS observations and experiments involving student education work include:

  • “The Commercial Generic Bioprocessing Apparatus Science Insert-01 (CSI-01) was the first in a series of experiments for the K–12 education program from BioServe Space Technologies at the University of Colorado-Boulder. This C. elegans experiment involved over 5,000 middle school students (grades 6 – 9) who were located in Texas, Arizona, Michigan, Florida, California, New Mexico, Wisconsin, and Montana, as well as several thousand students from Malaysia. The C. elegans experiment was part of the Orion’s Quest education program (http://www.orionsquest.org/); video of the worms are available on the Web site”. (p 169).
  • “CSI-02 is an educational payload that is designed to interest middle school students in STEM by providing the opportunity for these students to participate in near-real-time research conducted on board the ISS. Each experiment was designed to be easily reproducible in the classroom, providing hands-on experience to the students. The seed germination and plant development experiment provided the opportunity for younger students to begin to understand how gravity affects germination and plant development. Small seeds were germinated on orbit in BioServe-developed hardware. The students examined root and stem growth and plant development over a period ranging from a few weeks to 2 months. Classroom kits were available from BioServe for teachers”. (p 171)
  • “The objective of the Education Payload Operations (EPO) investigation was to use toys, tools, and other common items in the microgravity environment of ISS to create educational video and multimedia products that inspire the next generation of engineers, mathematicians, physicists, and other scientists. To date, over 500 videos, DVDs, and video clips have been produced and distributed to science teachers and schools throughout the United States”. (p 173)
  • During the Education-Space-Exposed Experiment Development for Students (SEEDS) experiment, eight pouches of soybean and corn seeds flew on ISS and germinated under either dark or lighted conditions. (p 179)

  • Soldering in Reduced Gravity Experiment (SoRGE). (p. 196)
  • Exploration Lessons Learned from the Operation of ISS. This is left to the reader, as a summary of “non-eigenaxis attitude trajectory” is not possible within the space available. Read pp 197-198 and referenced publications.
  • Medical Monitoring of ISS Crewmembers, Exploration Lessons Learned from the Operation of ISS. Several papers have been published reporting the engineering and operational ramifications resulting from the data that were collected from the ISS space environment. The results fall into a couple of broad categories (p. 199):
    • Radiation environmental effects on ISS
    • External contamination of ISS
    • Other environmental assessments, including thruster plume contamination and condensate venting

The report is a great read, full of interesting, odd and bizarre research projects. A lot of the work depends on the ISS. And the expansion to a full six crew members makes future research a lot more feasible. Now that we have it, lets see what the International Space Station can do for human space flight research.
