Query: A Mission to Nature's Telescope for High-Resolution Imaging of an
  Exoplanet   The solar gravitational lens (SGL) provides a factor of $10^{11}$
amplification for viewing distant point sources beyond our solar system. As
such, it may be used for resolved imaging of extended sources, such as
exoplanets, not possible otherwise. To use the SGL, a spacecraft carrying a
modest telescope and a coronagraph must reach the SGLs focal region, that
begins at $\sim$550 astronomical units (AU) from the Sun and is oriented
outward along the line connecting the distant object and the Sun. No spacecraft
has ever reached even a half of that distance; and to do so within a reasonable
mission lifetime (e.g., less than 25 years) and affordable cost requires a new
type of mission design, using solar sails and microsats ($<100$~kg). The payoff
is high -- using the SGL is the only practical way we can ever get a
high-resolution, multi-pixel image of an Earth-like exoplanet, one that we
identify as potentially habitable. This paper describes a novel mission design
starting with a rideshare launch from the Earth, spiraling in toward the Sun,
and then flying around it to achieve solar system exit speeds of over $20$
AU/year. A new sailcraft design is used to make possible high area to mass
ratio for the sailcraft. The mission design enables other fast solar system
missions, starting with a proposed very low cost technology demonstration
mission (TDM) to prove the functionality and operation of the microsat-solar
sail design and then, building on the TDM, missions to explore distant regions
of the solar system, and those to study Kuiper Belt objects (KBOs) and the
recently discovered interstellar objects (ISOs) are also possible.
