We explore the concept of liquid Argon time projection chamber (TPC) for
gamma-ray astronomy in the 100 MeV — 1 TeV energy range. We propose a basic
layout for such a telescope called MAST. Using a last-generation rocket such as
Falcon Heavy, it is possible to launch a detector with the effective area and
the differential sensitivity about one order of magnitude better than the
Fermi-LAT ones. At the same time, the MAST concept allows for an excellent
angular resolution, 3-10 times better than the Fermi-LAT one depending on the
energy, and good energy resolution ($approx$ 20 % at 100 MeV and 6-10 % for
the 10 GeV — 1 TeV energy range). We show that such a telescope would be
instrumental in a broad range of long-standing astrophysical problems.
