Descripción
The GTC Adaptive Optics (GTCAO) system will provide diffraction-limited capabilities in the near infrared to the GTC telescope. At first, it will use a Natural Guide Star (NGS) as a reference source, and later it will be upgraded to a Sodium Laser Guide Star (LGS), which will significantly increase the sky coverage. The GTCAO system is expected to provide a strehl ratio of 0.65 in the K-band with a bright NGS and a minimum strehl ratio of 0.1 with the LGS using a tip-tilt star brighter than 18 mag. We will review the current status of the performance tests of the GTCAO system in the IAC laboratory, and present the development of the LGS system at the IAC, which is currently in the detailed design phase.

    NEOMIR: ESA's space-based infrared mission for NEO detection and early warning
    The Near-Earth Object Mission in the Infra-Red (NEOMIR) is the first ESA's space-based mission fully dedicated to discovering near-Earth objects (NEOs), with a focus to detect and raise early warning for the smaller objects that are coming from the Sun direction, thus nearly impossible to be detected by ground-based optical survey. NEOMIR is

    Upgrading the polarisation modulation unit of the Gregor Infrared Spectrograph
    The Gregor Infrared Spectrograph (GRIS) is installed at the Gregor telescope at Observatorio del Teide, Spain. The instrument started observations in 2012 and underwent several upgrades in the following years. Currently, it is experiencing the most significant upgrade so far, which includes, among other things, adding two optical channels to

    Small-ELF Telescope opto-mechanical system: progress on design, manufacturing, and tensegrity prototyping
    Small-ELF (SELF) is a 3.5-meter telescope currently entering the manufacturing phase and will serve as a technology precursor for the much larger telescope named ELF (Exo-Life Finder). The primary objective of the proposed design approach is to to radically improve the system's capabilities for the detection of biomarkers and life in the
