a Examples include gamma-ray spectroscopy, submillimeter spectroscopy, and x-ray imaging.

b Three small ground-based programs and one space initiative are highlighted by italics since they were regarded by the committee as being of special scientific importance.

In addition to the instrument initiatives recommended in this section, the committee stresses that progress in astronomy requires a vigorous program of theoretical research and laboratory astrophysics, in addition to a balanced program of observation. The vital role of theory and that of laboratory astrophysics are discussed further in Chapter 3.
