Monitoring the architecture of science: a studious, imaginative investigation of space-bound and land-based far-traveling and distant-looking orbiting and non-orbiting structures

an ongoing weekly project distributed by e-mail running from February 2009 to February 2010.

The Cassini spacecraft, orbiting within the Saturn system since 2004, took images in July 2009 revealing significant periodical brightness variation in the planet’s rings; these variations, potentially caused by a collision with comet or asteroid in the 1980s, are characterized by “rippled” or “corrugated” areas that extend for up to 11,000 miles

On November 13, 2009, the European Space Agency’s Rosetta spacecraft made its third and final swing-by of Earth, using Earth’s gravity to propel it towards its future destinations: a “close encounter” with asteroid 21 Lutetia in July 2010 and its approach to – and landing on – the 67P/Churyumov-Gerasimenko comet in mid-2014 After recording no “targets” in its observation log on November 24 and 25, the European Space Agency’s Herschel Space Observatory records nine targets on November 26 and seven targets on November 27 and 28
