(1)The Mid Infrared Instrument (MIR) which will help to increase the telescopes wavelength coverage.

(2)The Near Infrared Camera(Nir Cam) will search for the early signs of star and galaxy formation as well as supernovas and the light curves that are given off by these exploding stars in addition to these tasks it will also map dark matter by gravitational lensing and will also be used for wave front sensing to help control the primary mirror.

(3)The Near Infrared Spectrograph (NirSpec) will provide wide field and deep imaging of the spectra given off by up to 100 different objects simultaneously in a 3x3 arc minute field of view.

(4)The Turntable Filter Imager (TFI) will be used primarily for scientific observations. The Webb telescope unlike the Hubble will not be serviceable due to its L2 orbit, L2 is an orbital path between the earth and the sun that allows an object to maintain a constant distance from the earth. So the instruments it takes with it will be the only ones it ever has if they become inoperable they will be no way to repair them.
