As chair of the ALMA Science Advisory Committee (ASAC), I am co-ordinating the assembly of science justifications for developments of the ALMA.

A team of twelve scientists covering the range of science areas from the solar system to cosmology are putting together an updated justification.

All parties interested in using ALMA are encouraged to get in touch with members of the science advisory committees to have an input to the process.
