Query: Silica aerogel for capturing intact interplanetary dust particles for
  the Tanpopo experiment   In this paper, we report the progress in developing a silica-aerogel-based
cosmic dust capture panel for use in the Tanpopo experiment on the
International Space Station (ISS). Previous studies revealed that
ultralow-density silica aerogel tiles comprising two layers with densities of
0.01 and 0.03 g/cm$^3$ developed using our production technique were suitable
for achieving the scientific objectives of the astrobiological mission. A
special density configuration (i.e., box framing) aerogel with a holder was
designed to construct the capture panels. Qualification tests for an
engineering model of the capture panel as an instrument aboard the ISS were
successful. Sixty box-framing aerogel tiles were manufactured in a
contamination-controlled environment.
