Seeing Temperatures

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...

Launching a Balloon to the Edge of Space

The STEM club from Holy Cross School in Chorley and the North West Local Centre of the Royal Meteorological Society collaborated on a project to launch a balloon into the atmosphere. The balloon was carrying a camera, a GPS transmitter and a radiosonde, an instrument which transmits measurements by radio waves back...

Gardens in the Sky

This Catalyst article investigates how plants can be grown in orbiting spacecraft and how this may be useful in future manned space missions.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.

Catalyst is a...

Exploring Saturn

A Catalyst article following the journey of the space probes Huygens and Cassini, sent to explore Titan, a moon of Saturn. After a seven year journey Huygens was set to fall through the atmosphere transmitting data back to Earth via Cassini so more can be learnt about this distant moon. The article describes the...

Exploring Mars: Landers

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.

Designs on Space: the Lifecycle of a Satellite

A Catalyst article about designing, building and testing a spacecraft. There are thousands of man-made satellites orbiting the Earth. Some are only a few hundred kilometres above the Earth and complete one orbit roughly every 90 minutes. Geostationary satellites are located around 40 000 kilometres from the surface...

Balloons in Space

The Big Picture on pages 10-11 of this issue of Catalyst shows scientists in Antarctica launching a balloon which will travel up through the atmosphere to a height of 34 km above the Earth’s surface. This balloon is part of NASA’s BARREL mission, probing the radiation belts which surround the Earth.

Building Images

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.

Observatories and Telescopes

These are images of some of the European Southern Observatory telescopes and locations. They include:

* View from above ESO's La Silla observation site in the southern part of the Atacama desert, 600 km north of Santiago de Chile. The site is 2,400 metres above sea level, providing excellent observing...

Nebulae

This resource contains stunning images of nebulae, produced by the European Southern Observatory (ESO). The images include:

* View of the Orion Nebula (Messier 42), lying about 1,350 light-years from Earth, taken with the VISTA infrared survey telescope at ESO’s Paranal Observatory in Chile.

* A...
