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/cm3 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… 
Ultralow-density double-layer silica aerogel fabrication for the intact capture of cosmic dust in low-Earth orbits
The fabrication of an ultralow-density hydrophobic silica aerogel for the intact capture cosmic dust during the Tanpopo mission is described. The Tanpopo experiment performed on the International
Detection of Biological Bricks in Space. The Case of Adenine in Silica Aerogel
It is shown that it is possible to detect traces of adenine using surface-enhanced Raman spectroscopy (SERS) and can be extended in the frame of Tanpopo missions for studying the interplanetary transfer of prebiotic organic compounds of biological interest.
Spin-Off Application of Silica Aerogel in Space: Capturing Intact Cosmic Dust in Low-Earth Orbits and Beyond
A spin-off application of transparent, low-density silica aerogel as a dust-capture medium in space is described. We provide an overview of the physics behind the hypervelocity capture of dust using
Scientific Targets of Tanpopo: Astrobiology Exposure and Micrometeoroid Capture Experiments at the Japanese Experiment Module Exposed Facility of the International Space Station.
The Tanpopo experiment was the first Japanese astrobiology mission on board the Japanese Experiment Module Exposed Facility on the International Space Station to address two important astrobiological topics, panspermia and the chemical evolution process toward the generation of life.
A review of recent progress on the silica aerogel monoliths: synthesis, reinforcement, and applications
The silica aerogel monoliths (SAMs) with three-dimensional (3D) porous structures showing unique physical and chemical properties promise a new era of technologies. However, the critical challenge
Investigation of the Interplanetary Transfer of Microbes in the Tanpopo Mission at the Exposed Facility of the International Space Station.
The goal of this review is to introduce an overview of the Tanpopo mission with particular emphasis on the investigation of the interplanetary transfer of microbes.
Robust urethane-bridged silica aerogels available for water-carved aerosculptures
Molecular bridged silica aerogels have received extensive interest in recent years due to their easily controlled mechanical properties varying with different organosilane precursors, and without any
Space as a Tool for Astrobiology: Review and Recommendations for Experimentations in Earth Orbit and Beyond
The space environment is regularly used for experiments addressing astrobiology research goals. The specific conditions prevailing in Earth orbit and beyond, notably the radiative environment
Environmental Data and Survival Data of Deinococcus aetherius from the Exposure Facility of the Japan Experimental Module of the International Space Station Obtained by the Tanpopo Mission.
The measurements of temperature, radiation dosimeter and vacuum ultraviolet dosimeter in the EP, and survival data of Deinococcus aetherius are consistent with survivalData of microbes and organic compounds, which will be presented elsewhere in detail.
The non-destructive separation of diverse astrobiologically relevant organic molecules by customizable capillary zone electrophoresis and monolithic capillary electrochromatography
It is shown that a capillary electrochromatography approach using monolithic stationary phases with tailor-made surface chemistry can separate and identify various polycyclic aromatic hydrocarbons, nucleobases and aromatic acids that could be formed under astrophysically relevant conditions.
