GOODs used the Hubble Space Telescope’s Advanced Camera for Surveys with four filters, centered at 435, 606, 775 and 850& nm. The resulting map covers 30 times the area of the Hubble Deep Field to a photometric magnitude less sensitivity, and has enough resolution to allow the study of 1& kpc-scale objects at redshifts up to 6, and provides photometric redshifts for over 60,000 galaxies within the field, providing an excellent sample for studying bright galaxies at high redshifts.

The Hubble Space Telescope has three Fine Guidance Sensors (FGSs). Two are used to point and lock the telescope onto the target, and the third can be used for position measurements – also known as astrometry. Because the FGSs are so accurate, they can be used to measure stellar distances and also to investigate binary star systems.

The three FGSs are located at 90-degree intervals around the circumference of the telescope’s field of view. To achieve the very high pointing accuracy Hubble needs, the FGSs have been constructed as interferometers to exploit the wavelike features of the in-coming starlight. With this kind of accuracy and precision, the sensors can search for a wobble in the motion of nearby stars that could indicate the presence of a planetary companion, determine if certain stars really are double stars, measure the angular diameter of stars, galaxies, etc.

The camera can image two adjacent fields of view, each approximately 2.4 arc-minute × 2.4 arc-minute in size, and can also be configured to read out small 8 × 8 pixel subarrays at a rate of 16 times per second. Even with these short integration times, the FGS is sensitive enough to reach 58 µJy at 1.25 µm (~Jab = 19.5). This combination of sky coverage and sensitivity ensures that an appropriate guide star can be found with 95% probability at any point in the sky, including high galactic latitudes.

Due to the sensitivity of the FGS they can not be used whilst the HST is pointed within 50 degrees of the sun.

Microvariability and Oscillations of STars telescope, better known simply as MOST, is Canada’s first and (as of mid-2005) only space telescope. It is also the smallest space telescope in the world (for which its creators nicknamed it the “Humble Space Telescope”, in reference to one of the largest, the Hubble). MOST is the first spacecraft dedicated to the study of asteroseismology.

The Hubble Space Telescope received the Soft-Capture Mechanism (SCM) on STS-125. The SCM is meant for unpressurized docking, but uses the LIDS interface to reserve the possibility of an Orion docked mission. The docking ring is mounted on Hubble’s aft bulkhead. It will be used for safely de-orbiting Hubble at the end of its service lifetime, as the telescope does not have any thrusters.
