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.
Science News – Womb Transplants
It has recently been announced that one of the first women to receive a womb transplant has given birth to a healthy baby boy. But what are womb transplants and how significant is this development?

We get Wesley Williams from FamilyGamerTV to go hands on with the Angry Birds Epic role-playing game on the iPad and delve deep into the first levels of Red’s quest to recover the stolen eggs from the evil Wiz Pig! Watch as we fight off a variety of King Pig’s subjects in turn-based battles, free Chuck from their evil clutches, explore our first dungeon and craft a new weapon with all the loot we acquire along the way.
6 Things Kids with Special Needs Wish EVERYONE Would Do
When we published our article 6 Things Parents Wish Their Kids Would Do … and 6 Things Kids Wish Their Parents Would Do, one of our readers got in touch to say we should do one for the things that kids with special needs wish EVERYONE would do. So we asked our followers, and came up with this list.
It was a bit tricky to put the list together, because there are so many different kinds of “special needs”. For some children, their disability is quite well manageable with medication, or with assistance and therapy, and you’d hardly know they had any additional needs. You may have heard of autism or Asperger’s Syndrome – these are part of the autistic disorder spectrum, a range of conditions that affect how people communicate and relate to people around them. You can’t tell by looking at someone if they have ASD.
Other children have disabilities that are apparent when you meet them, such as those with Down’s Syndrome, which we have covered in more detail here. Or they might use a wheelchair to get around.
What thing do they all have in common? They sometimes get asked really silly questions, and get treated badly by people. Make sure you aren’t one of them, by listening to what the kids (and their parents) had to say!
