Long-time ground-ball-looker: A new space box that will help us understand how quickly our ground ball is warming

Our ground ball is warming because it gets more light from the Sun than it sends out to space. Our ground ball is sending out less light now than it did a few years ago, and less than we expected, which is concerning because this means that the ground ball will keep warming for longer.

It is important to understand the light going in and out, and to continue looking at it to see how it changes over time. There are space boxes that look at the light right now, but these boxes will stop looking in a few years, so there are plans for new space boxes that will look later.

We are working on a new space box called the long-time ground-ball-looker ('ECO'). By looking up and down at the same time, this box will help us know how much light is going in and out every year. This will help us understand how quickly our ground ball is warming, and make it easier to figure out when it will stop warming.
