ISRO realigns MOM orbit to prevent impact of eclipseIndian Space Research Organisation has successfully realigned the orbit of its Mars Orbiter Mission 'Mangalyaan.'

The aim is to ensure that the study is not affected by long-duration eclipse.

The duration of the eclipse was so long that the Mangalyaan's battery capacity would have got exhausted due to lack of sun rays.

ISRO therefore, manoeuvred to change the orbit of Mangalyaan and reduced the duration of eclipse.

MOM still has 30kg fuel left, and with realignment it will work longer.

The correction in the trajectory of Mangalyaan was required to keep the power supply strong during the eclipse.

It is caused by shadow of Mars falling on it for 7-8 hours so that it could continue to function longer.

This is because Mangalyaan's battery cannot support long-duration eclipse.
