Here they are. These bits of ancient space rock may hold clues to how the rocky planets formed, including Earth.⁣ ⁣ For the next two years, the #OSIRISREx science team will continue studying the samples. NASA will preserve at least 70% of the sample at NASAJohnson for further research by scientists worldwide, including future generations of scientists. ⁣ ⁣ Asteroids are leftovers from the period of planet formation, so by studying asteroids, we can learn what existed in our solar system before Earth fully formed. Was there already water? Organic molecules? DNA? RNA? ⁣ ⁣ Initial studies of this asteroid sample show evidence of high concentrations of carbon and water, which, when found together, are among the building blocks of life as we know it on Earth. ⁣ ⁣ Image Descriptions:⁣ 1.
