Why are there missing GRACE data?

The batteries onboard GRACE have degraded over time so the instrument is turned off when the satellite is in eclipse (in Earth's shadow) and turned back on when in sunlight since the batteries are solar charged.

Re: passing time of the GRACE satellite

Thank you for your inquiry. Please see the following response from the GRACE science team: Neither GRACE nor GRACE-FO have a repeat orbit, so there is no such thing as a specific time at which the satellites pass over a specific location during the month. The ...
