Nasa delays next Mars probe due to leaky seal on instrument

InSight spacecraft, designed to study planet's interior, will not launch in March as planned because of flaw in seismometer pouch

Nasa is calling off its next probe mission to Mars because there isn't enough time to fix a leaky seal on a key science instrument.

The InSight spacecraft was set for launch in March. The problem is with a protective pouch around the lander's seismometer, which was designed to measure ground movement on the planet.
