  We present an up-to-date estimate for the prospect of using the
Astrodynamical Space Test of Relativity using Optical Devices (ASTROD) for an
unambiguous detection of solar g modes (f < 400 micro Hertz) through their
gravitational signature. There are currently two major efforts to detect
low-frequency gravitational effects, ASTROD and the Laser Interferometer Space
Antenna (LISA). Using the most recent g mode surface amplitude estimates, both
observational and theoretical, it is unclear whether LISA will be capable of
successfully detecting these modes. The ASTROD project may be better suited for
detection as its sensitivity curve is shifted towards lower frequencies with
the best sensitivity occurring in the range 100-300 micro Hertz.
