In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

These images, from NASA, show crafts that have been used in the surface exploration of Mars. They illustrate space exploration including the Mars Viking lander which looked for signs of life on Mars.

From NASA, these images show astronauts from early space missions, to the space shuttle and international space station. The images can be used to illustrate human space exploration in a range of resources. Yuri Gagarin was the first human in space and Neil Armstrong, part of the Apollo 11 mission, was the first...

This lesson, from the Science and Technology Facilities Council (STFC), looks in particular at how infrared data is collected and used to measure changes in global temperature. Infrared radiation is part of the electromagnetic spectrum of light which has uses in astronomy, communications, surveillance and medicine...

This Nuffield Secondary Science picture pack was designed for use with Field of Study 4.3 in Theme 4. The pack contains 10 pages of black and white images of equipment related to the generation and use of electricity on a large scale. The pack was published in...

Humans have landed on the Moon. These images, from NASA, show some of the Lunar rovers that have been involved in manned Lunar explorations and some that may be developed for future missions to the Moon.

On July 20, 1969, the astronaut Neil Armstrong was the first human to set foot on the moon. From NASA, these images illustrate the story behind "One small step for a man, one giant leap for mankind." Truly a milestone moment in space exploration.

NASA’s Mars exploration rovers Spirit and Opportunity were sent to the planet to investigate its geology. Accurate images of the surface were needed so that possible areas to investigate could be selected and then the rover directed towards them. The cameras on board the rovers can only record black and white...

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...
