We're scientists, engineers & communicators for NASA's Cassini mission, which makes its #GrandFinale plunge into Saturn next week. AUA!
Our short bio: After two decades in space, NASA's Cassini spacecraft is nearing the end of its remarkable journey of exploration. Having expended almost every bit of the rocket propellant it carried to Saturn, we will deliberately plunge Cassini into the planet on Sept. 15. Why? To ensure Saturn's moons will remain pristine for future exploration—in particular, the ice-covered, ocean-bearing Enceladus, but also Titan, with its intriguing pre-biotic chemistry. Only one week remains before the spacecraft's final chapter in the skies of Saturn. What would you like to know about the science and engineering still to come for Cassini? Ask us anything!
Update at 5:11 p.m. ET: We took your questions on Friday, Sept. 8 from 3 to 5 p.m. ET (noon-2 p.m. PT, 1900-2100 GMT). Time to log off and get back to the final week of the Cassini spacecraft. Thanks for joining us here today! We hope you'll be watching on Sept. 15 during the final plunge as we stream live from mission control: http://nasa.gov/live
