1. A system for isolating vibration among a plurality of instruments on a spacecraft, comprising: at least two separate platforms, each of which is coupled to and configured to isolate vibration for a respective set of the plurality of instruments on the spacecraft,wherein the at least two separate
1. A system for isolating vibration among a plurality of instruments on a spacecraft, comprising: at least two separate platforms, each of which is coupled to and configured to isolate vibration for a respective set of the plurality of instruments on the spacecraft,wherein the at least two separate platforms mounted to a nadir facing deck of the spacecraft,wherein each of the at least two separate platforms comprises a mounting interface configured to mount a corresponding one of the at least two separate platforms to the spacecraft, andwherein each mounting interface comprises a plurality of struts and a strut geometry configured to provide damped isolation modes within a predefined frequency band. 2. The system of claim 1, wherein the number of the at least two separate platforms equals the number of the plurality of instruments, so that each of the plurality of instruments corresponds with a respective platform. 3. The system of claim 1, wherein the plurality of instruments comprise an imager and a sounder. 4. The system of claim 1, wherein each of the at least two separate platforms is configured to perform attitude sensing. 5. The system of claim 4, wherein each of the at least two separate platforms comprises at least one of a star tracker and an inertial measurement unit (IMU), configured to perform the attitude sensing. 6. The system of claim 1, wherein each mounting interface comprises six struts. 7. The system of claim 1, wherein each of the at least two separate platforms comprises an instrument-coupling side and a spacecraft-mounting side opposite the instrument-coupling side. 8. The system of claim 7, wherein the at least two separate platforms are configured such that when the at least two separate platforms are mounted to the same side of the spacecraft as one another, the instrument-coupling side of each of the at least two separate platforms faces the same direction as one another. 9. Th system of claim 1, wherein the at least two separate platforms are coplanar with one another. 10. A spacecraft having a plurality of instruments thereon, the spacecraft comprising: a system for isolating vibration among the plurality of instruments,wherein the system comprises at least two separate platforms, each of which is coupled to and configured to isolate vibration for a respective set of the at least one of a plurality of instruments on the spacecraft,wherein the at least two separate platforms are mounted to a nadir facing deck of the spacecraft,wherein each of the at least two separate platforms comprises a mounting interface configured to mount a corresponding one of the at least two separate platforms to the spacecraft, andwherein each mounting interface comprises a plurality of struts and a strut geometry configured to provide damped isolation modes within a predefined frequency band. 11. The system of claim 10, wherein the number of the at least two separate platforms equals the number of the plurality of instruments, so that each of the plurality of instruments corresponds with a respective platform. 12. The system of claim 10, wherein the plurality of instruments comprise an imager and a sounder. 13. The system of claim 10, wherein each of the at least two separate platforms is configured to perform attitude sensing. 14. The system of claim 13, wherein each of the at least two separate platforms comprises at least one of a star tracker and an inertial measurement unit (IMU), configured to perform the attitude sensing. 15. The system of claim 10, wherein each mounting interface comprises six struts. 16. The system of claim 10, wherein each of the at least two separate platforms comprises an instrument-coupling side and a spacecraft-mounting side opposite the instrument-coupling side. 17. The system of claim 16, wherein the at least two separate platforms are configured such that when the at least two separate platforms are mounted to the same side of the spacecraft as one another, the instrument-coupling side of each of the at least two separate platforms faces the same direction as one another. 18. The system of claim 10, wherein the at least two separate platforms are coplanar with one another.
