Scientists in GISRO’s research lab were developing new suits for space travel. They were making some final adjustments and testing them when the lead scientist, Aasman, saw a notification pop up on her screen. Someone was trying to steal their code. 

“Aakash!” she called to her assistant. “Can you check what’s going on? Who is trying to extract our code from the new space suits?”  

Aakash clicked some buttons, checked some screens and his face fell. “We can’t locate the source. We’ll have to talk to the three astronauts who were running the tests.” 

When they spoke to them, this was what they learnt:

After hearing their testimonies, Aasman said, “One of you is lying. Please confess before I’m forced to expose you.”  

Who do you think she suspects and why?
