IN early April, Nasa’s latest Mars lander detected a tremor on the Red Planet. But Nasa only announced the news in mid-April. This was the first time humans have detected a
quake on Mars – or a ‘marsquake’.
The shaking that InSight felt was slight, but it still made researchers very excited. This is because the tremor meant Mars’s crust is still active. However, Mars’s surface
does not have different plates like Earth; it is more like the Moon.
Since this first quake, InSight has felt three more tremors. Scientists are analysing this data to try to find out how Mars formed. Philippe Lognonne, the lead scientist in the
tremor detection team, said, “We’ve been waiting months for a signal like this.”
