A Trip to Mars!
Imagine being able to catch a flight to Mars as easily as we travel to another country – that was the idea behind the Trip To Mars session I attended at the Cheltenham Science Festival. It was conducted by Dr Suze Kundu and Dr Simon Foster and presented as a pre-flight safety briefing, with both of them dressed as pilots! There were a lot of humorous moments and sci-fi references but also some great science.
Suze and Simon suggested that in the future, flights to Mars could be far quicker than they are now, and explored how some of the bigger problems could be overcome. For example, the Sun’s magnetic field deflects a significant proportion of the cosmic radiation that could be harmful to humans on Earth; as spaceships travel further away from the Earth and Sun they will have less protection because the magnetic field weakens. To combat this it’s possible that spaceships will contain or be covered with large and powerful magnets, to produce the same deflective effect. This would have the added advantage of also deflecting radiation from solar flares.
Spaceships journeying to Mars would travel at such speed that even tiny fragments of rock and dust could be damaging to the hull. To combat this, and also the heat generated when the spaceship passes through an atmosphere, Suze and Simon discussed the possibility of spaceships being coated in aerogel. This amazing material is a solid formed from silicone dioxide but is 98% air; this means that it is extremely light but also strong. Its melting point is 1,200°C (equivalent to asbestos) and it is a wonderful insulator. Because it consists of large pockets of air between thin layers of silicone dioxide, any dust or rock fragments that hit it would be slowed and stopped before they could penetrate the aerogel completely.
Suze and Simon also discussed the possibilities and problems with cryostasis. Theoretically this is when a person’s body is cooled to temperatures so low that they enter hibernation, ideal for long journeys through space. Unfortunately our technology isn’t advanced enough to do this at the moment; any attempt would result in the cells rupturing and the person dying. But in the future it will be possible, perhaps after the person’s DNA has been altered slightly so that they can produce antifreeze proteins like some species of wasps and turtles.
What is it Like to Grow Up in Finland?
My husband lived in Finland for two years before he met me. I love listening to his stories of the cold, the beauty, the fun he had and the wildlife (including wolves) he saw. Finland is called the Land of a Thousand Lakes. Sometimes I imagine what it would be like to grow up in Finland.
Untangling Quantum Entanglement and Teleportation – A Child-friendly Explanation
You may have heard something on the news recently about an exciting scientific discovery, of Quantum Entanglement and Teleportation. Sometimes it can be quite hard to untangle a news story like this, because it all sounds rather complicated. Our new Science Writer, Samantha Gouldson has ironed out the details and explains Quantum Entanglement and Teleportation in a child-friendly manner.
CURIOUS CREATURES 2 – The Stag Beetle
The strangest creatures are, to me,
The ones I love the best.
The creepy, crawly and the odd
Are cooler than the rest…
These magnificent beasties are the armoured vehicles of the insect population and the largest terrestrial-dwelling beetles in the UK. Their common name is a reference – unsurprisingly – to their antler-shaped “mandibles” or jaws, which they use to fight over territory, but not, perhaps surprisingly, to win the respect of female Stag Beetles..!
These Curious Creatures have intrigued me ever since I found an expired female stag beetle (see below ) in a south-west France many years ago. I drew it next to a blackbird’s feather, captivated by the different tones of black, the textural contrasts and inky depths of colour. I found it – and still find them all as a species – fascinating and beautiful, particularly the males, with their extraordinary maroon-red mandibles.

Connection Infection – Poetry by Kids
News scrolling on a bright screen
Eyes scanning down a magazine
Locked up in a daydream
Obsessed by the latest Instagram post I’ve seen
I’m infected with a virus
That I can’t get out of my head
It’s got me going crazy
At least; that’s what the comments said
Hairstyles and creations
‘Urgent’ messages from relations
The latest trends and how to cook
Living life by an electronic book
I’m infected with a bug
That’s connected to my hands
That’s left me solitary
Unware of and blind to the past
We used to talk face to face
Of politics, clothes and space
But then you were replaced
By a cruel-minded interface
My alarm’s a notification
I’m dictated by cold metal parts
My day scheduled on reaching the leader boards
The social media bug has infected my heart
