The Hubble Space Telescope has been given new life with the successful Servicing Mission 4 (SM4). The goal of each servicing mission to the telescope has been to replace instruments and other system components that would enable better science productivity and enlightenment. But never before has the notion of repairing existing broken instruments in the telescope been considered because of the complexity of such an activity... until now. During SM4, two new scientific instruments were installed – the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3); two failed instruments, the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS), were brought back to life by the first ever on-orbit repairs; and, the spacecraft original batteries were replaced with new ones that will keep HST powered well into the next decade. But what will the scientific observations look like? The evidence is here with the release of the early observations from each instrument, and the news is wonderful!

This talk presents the current status of the commissioning of the GTC. It covers the progress made since first light, the current performance and then looks ahead to what is expected between now and the start of science operations in March.

SIDE (Super Ifu Deployable Experiment) is being proposed as a new instrument for the GTC 10.4m telescope on La Palma. It will be a wide-field fiber-fed spectrograph of intermediate resolution, highly efficient in multi-object and 3D spectroscopy. SIDE will feature the unique possibility of performing simultaneous visible and NIR observations for selected spectral ranges. SIDE will produce unique data sets and open new opportunities to understand our view on galaxy formation and evolution and it will provide new insights on the physics of the dark universe. In this talk I will give a brief instrument overview and review the status of SIDE and its pathfinder, the mini SIDE. The SIDE project is lead by the Instituto de Astrofísica de Andalucia in Granada (Spain).
