Particles have been found safe inside the crashed Genesis space capsule, say scientists at Nasa.
The probe was on a three year mission to capture particles of solar wind to try to discover how the sun formed.
Genesis fell to Earth on Wednesday after a battery failure meant its parachute didn't open, and experts were worried all their work was ruined.
Physicist Roger Wiens said : "We should be able to meet many, if not all, of our primary science goals."
