NASA-JPL InSight engineer Marleen Martinez Sundgaard works in a simulated Martian sandbox. She tests science instruments meant for Mars right here on Earth. Growing up in a migrant farming family, Marleen was always dreaming of the stars — now her dream has become a reality.
Landing in November 2018, NASA's InSight will probe beneath the surface of Mars, study the planet's interior and shed light on how rocky planets — inside and outside our solar system — form.
