On Mar 14, 2024, the giant Starship rocket was successfully launched and reached the orbit by SpaceX. The exciting future is rapidly approaching and changing. In the realm of astronomical scientific exploration, cutting-edge advancements in ground and space camera systems are reshaping our understanding of the cosmos through time travel visiting the past of cosmos. I will present SALTUS (Single Aperture Large Telescope for Universe Studies), a visionary mid/far-infrared telescope concept featuring an inflatable membrane mirror – approximately 14 meters in scale. Through its scalable design, this deployable space telescope leverages an all-encompassing optical architecture that taps into the uncharted potential of an immensely vast aperture. A series of prototypes for the inflatable mirror have been born, nurtured, and subjected to systematic tests. Enter the realm of high dynamic range, non-null Thermo-Vacuum (TVAC) tests, complete with deflectometry. Under these simulated space conditions, the optical performance of the inflatable mirror has been verified and validated. But that's not all. Enter the Nautilus space telescope array observatory, a concept that pushes the boundaries of possibility further. This visionary mission paves the way for a scalable telescope array of unprecedented dimensions. Key to Nautilus's grand vision is the application of multi-order diffraction engineered (MODE) optics. In the endless pursuit of scalable space technology, researchers are charting new frontiers in large dynamic range metrology solutions. Simultaneous sensing capabilities add yet another feature to the capabilities.
