This is the first time a fully space-qualified device of this type has ever been flown, and the first to be flown on the outside of a satellite.

Often people associate small with being frail. But our tiny shutters, which don't touch when they close, are exceptionally strong, especially when operating in space where there's no gravity, weight or resistance forces to wear or degrade moving parts.

When the satellite is facing the sun, for example, you could cool it by closing our shutter doors and reflecting the heat. Or if you need to absorb more heat, the shutters would open.

It's finally great to put together two really great sets. I think that's the first time I've done that all season. I played some of the best tennis I've played in my four years.

When everyone is really busy and feeling stressed out, often the time with your partner is one of the first things to get bumped. Stretching with your loved one turns the tables on the rat race, allowing you both to be in the moment and renewing your connection.
