The true story of Opportunity, the Mars rover who captivated watchers on Earth, is the star of this picture book biography. Author Shaelyn McDaniel begins with a story of how humans set and achieved exploration goals: humans wanted to go to the sky, so we did. We wanted to go to the moon, so we did. But when we wanted to go to Mars, it was a little too far away, “so we sent a friend instead”. Opportunity , built by scientists, went into space and spent 15 years on what was originally 3 month mission, but a storm hit the planet, draining the rover’s batteries and shutting her down. McDaniel humanizes Opportunity with phrases like “Oppy called home often” and “she sent selfies so we would know she was okay”; as Opportunity shuts down, scientists sent a lullaby – “a kiss from her friends on Earth”. It’s an emotional moment, made more poignant by Cornelia Li’s digital illustration of a satellite broadcasting colorful musical notes into space. Much of the illustration is orange-red tinged, with and there are genuinely breathtaking moments as Opportunity roves the Red planet, groves digging into the ground and layered dunes. Endpapers show Mars from the Earth’s point of view and Earth from Mars’s point of view, and back matter includes more information about Opportunity. A bibliography is available via QR code. Hello, Opportunity will endear the rover to a new generation of sky-watchers who may be inspired to find her on Mars one day. A sweet storytime addition to your space collections. A downloadable activity kit includes games and the opportunity to send a postcard to Opportunity.
