Optical Design and Adaptive Optics
Mirror Segmentation and Wavefront Control
The next space telescope employs segmented primary mirrors with microactuators that correct surface errors in real time. This approach enables diffraction limited performance at visible and near infrared wavelengths, improving spatial resolution over previous generation instruments.
Coronagraphic and Starshade Pathways
Advanced coronagraphs suppress starlight to enable direct imaging of exoplanets, while external starshade missions can be coordinated for even deeper contrast. These techniques together expand the observable exoplanet population into temperate, rocky regimes.
Spectroscopy and Broad Band Imaging
Multi Object Slitless Spectroscopy Efficiency
Integral field units and slitless spectroscopic modes capture spectra for thousands of faint objects simultaneously, accelerating surveys of large scale structure and cosmic web tracing.
Infrared to Submillimeter Sensitivity
Cryogenic detectors extend sensitivity into the mid and far infrared, allowing the study of cold dust, planet formation disks, and high redshift galaxies with minimal thermal background interference.
Operations, Data Systems, and Mission Lifetime
Onboard Processing and Calibration Orchestration
Real time data processing pipelines perform flatfielding, astrometric calibration, and cosmic ray rejection before downlink, reducing ground system workload and improving archive usability.
Orbital Configuration and Thermal Management
Operating at the second Sun Earth Lagrange point, the telescope maintains stable thermal conditions, while periodic station keeping maneuvers optimize observational uptime and propellant reserves.
