India's mission to Mars has embarked on its year-long journey to the Red Planet. Renowned science communicator, Pallava Bagla, talks about the significance of India's $100m mission to Mars. The Indian Space Research Organisation Mars Orbiter Mission (MOM) complements "Maven", Nasa鈥檚 mission to Mars, but it comes at a fraction of the $700m cost. Nonetheless, at $100m, is it money well spent? What benefit is this hi-tech adventure to a country where many of its citizens are still without clean water and electricity?

One of Our Probes is Missing
What do you do (other than panic) when your probe is lost in space? The probe, Messenger, has been designed to travel to Mercury. It is made out of Lego-like blocks connected by a myriad of cables. But even robust and rigorous preparations can sometimes go awry. Back on Earth engineers' hearts flutter when Messenger goes off message and disappears from their monitoring screens. Click interviews Chris Krupiarz who works on spacecraft flight software at Johns Hopkins University.

TeenTech
The science broadcaster Maggie Philbin is the brains behind TeenTech, a scheme to get teenagers involved in technology and coding in particular. We have a special report with some of the children who took part in constructing mobile Lego-like robots on the day of the TeenTech event, as well as the programmers who have volunteered as demonstrators.
