The Mars rover Perseverance is sending back astonishing high resolution images from the surface, and soon its helicopter will be launched. Kechil walks us through the journey the signals have to take to reach NASA

It's a long time since we visited Uranus and Neptune: the 80's in fact. Scientists are proposing launching a mission to these planets in 2030. Not only that, but they are proposing that a mission to the ice giants could be used to measure gravitational waves.

Keith Gottscalk has a lifelong passion for space flight and some FMR listeners may have caught him speaking at a UCT Summer School on South Africa's history in space. Recently he has published a poetry book called 'Cosmonauts do it in heaven' and talks to Kechil about it. It is available now via www.modjajibooks.co.za, also available at Kindle.

Zodiacal light: what is it? Have you seen it? What has Mars got to do with it? Latest research from the Juno mission suggests that most of this dust originates from the Red Planet.

PhD student Erik Osinga in Leiden in The Netherlands tells us about his citizen science project Lofar Galaxy Zoo. You too can participate and help the astronomers to identify galaxies in outer space. The link to the project is:

There is also a tutorial video that helps people get started

More on Mars and that Perseverance rover.

February is the month of Mars this year with not one, not two, but three missions arriving at the Red Planet. Two represent the first interplanetary missions for the United Arab Emirates and China, the third being the US NASA Perseverance rover.

The latest from outer space: unusual star systems and a Japanese sample-return mission to an asteroid.

Dragonfly Aerospace is a new space technology company based in Stellenbosch. The CEO, Bryan Dean, tells Kechil all about it.
