As we near the end of the school year, we'll be looking back at the topics we've explored and give you an update on what's happened since - and invite you to answer some new questions!
Earlier in the year we asked whether Space exploration was worth the cost. You can see what people said here.
You can keep track of all space exploration stories here, but here's a few of our favourites. To answer the questions, add your comments at the bottom!
The private rocket company SpaceX has sent astronauts into space
It's the first time since the in nine years that American crew has made the journey from US territory. This represents a new way of funding space travel - the government agency Nasa will no longer own the space rockets, but will use vehicles owned by SpaceX a bit like a taxi! Q: How do you think this will change the future of space exploration?
There's been a big rise in demand for space flights
Virgin Galactic has said it will release more tickets for space flights to match a rising demand.
The company said it had received almost 8,000 registrations of interest for future commercial flights, double what it had recorded by the end of September 2013. Read the full story here. Q: Do you think its a good idea to release more tickets if people are asking to go into space?
Scientists discover that mud flows on Mars behave like 'boiling toothpaste'
Researchers werre keen to test how volcanoes that erupt with mud instead of molten rock might look on the Mars, so they did an experiment! These showed that mud flows behaved a bit like boiling toothpaste! Q: Remind yourself what our expert Abbie Hutty said about Mars, and do a bit more research too. Do you think humans should ever try to live there?
