RIME: the radar sounder on JUICE

Author Pedro LacerdaNo Opinions
The Radar for Icy Moons Exploration (RIME) is one of the scientific instruments on the European Space Agency's (ESA) Jupiter Icy Moons Explorer (JUICE) mission. RIME is a radar instrument designed to investigate the icy moons of Jupiter, particularly Ganymede and Europa, and to provide valuable insights into their subsurface structures and compositions. This is [...]

Studying the morphology of Jupiter’s icy moons and monitoring the planet’s atmosphere with JANUS

Author Pedro LacerdaNo Opinions
by Laetitia Le Deit, Gabriel Tobie, Benoît Seignovert 30/08/2023 JANUS is the visible camera onboard the JUICE spacecraft. It will be used to study the morphology and surface processes of icy moons and perform mapping of the clouds of Jupiter. It will substantially enhance our existing image database of the Jupiter system, through its expanded [...]

Live like an Astronaut

Author Pedro LacerdaNo Opinions
According to the dictionary, an astronaut is a person who is professionally trained to travel in a spacecraft. "Astronaut" is the term used by NASA since the start of their space programme.

Chandrayaan-3 to land near Lunar south pole

Author Pedro LacerdaNo Opinions
The Indian Space Research Organisation (ISRO) mission Chandrayaan-3 is due to land near the lunar south pole today. This will be the first Moon landing so close to the south pole. The landing will be soft, meaning the lander will survive on the surface. A rover, stored inside the lander, will roll out and explore [...]

Jupiter Great Red Spot

Author Pedro LacerdaNo Opinions
by Alexandra Pais Jupiter hosts the most wide and strong windstorm known in the solar system. The Great Red Spot is a huge anticyclone of hydrogen and helium winds, powered from inside the planet. It is probably the same storm that has been seen since the first telescopes were targeted to Jupiter’s surface, more than [...]

Downstream Applications – what, how, who?

Author Pedro LacerdaNo Opinions
Most startups create so-called downstream applications that make use of satellite data from the Copernicus or the Galileo programmes. Copernicus is the European Union programme of Earth Observation, which monitors our planet and environment. Galileo is Europe’s Global Navigation Satellite System (GNSS), providing improved positioning and timing information for European services and users. Copernicus, named [...]

On the Shoulders of Giants

Author Pedro LacerdaNo Opinions
The phrase "on the shoulders of giants" is often attributed to Sir Isaac Newton, although its origins can be traced back to earlier sources. The phrase captures the idea that knowledge and progress build upon the work and insights of those who came before us. It signifies the acknowledgment of the contributions of predecessors and [...]

Spectrometers and Spectrographs in Space and on Earth

Author Pedro LacerdaNo Opinions
Spectroscopy is the study of spectra, spectrography is the recording of the spectra, and spectrometry is the measure of spectra. The three terms are used almost interchangeably in astronomy, astrophysics and other disciplines. Spectra (plural of spectrum) are ways to look at light (or electromagnetic waves) where different wavelengths are represented separately. An example we [...]
