Dark Transit of Jupiter's First Satellite [PDF]

Nature, 1884
ON May 18, at 8h., on observing Jupiter with my 10-inch reflector, p. 252, I saw three very dark spots—one near the planet's centre, and two others not far advanced upon the east limb. These I took to be the shadows of satellites, and on reference found that the shadows of Satellites I. and II. were really upon the planet; also Satellite I. itself. The

The Transiting Exoplanet Survey Satellite [PDF]

SPIE Proceedings, 2016
The Transiting Exoplanet Survey Satellite (TESS) will search the solar neighborhood for planets transiting bright stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission. The spacecraft will be placed into a highly elliptical 13.7-day orbit around the Earth.
