There's a lovely new color HiRISE image of Spirit at Home Plate. It was captured on July 16 (sol 1,968), and Spirit is firmly entrenched at Troy, on the western side of Home Plate.

While Spirit has been stuck at Troy, it's been taking numerous opportunities to capture photos with dramatic twilight lighting. On sol 2,002 (three sols ago, or August 21), it gazed toward the setting Sun, snapping the shutter roughly once a minute.

A set of Mars image data taken by the Hubble Space Telescope a year ago was just released to Hubble's data archive. It was captured by Hubble's Wide Field and Planetary Camera 2 on January 30, 2008 when Mars was about 115 million kilometers from Earth.
