Rocknest 3 "Rocknest 3" rock on Mars - target of the ChemCam and APXS instruments on the Curiosity rover (October 5, 2012) (white-balanced image). Feature type Rock Coordinates 4°35′S 137°26′E / 4.59°S 137.44°E / -4.59; 137.44

**Rocknest 3** is a rock on the surface of [Aeolis Palus](/source/Aeolis_Palus), between [Peace Vallis](/source/Peace_Vallis) and [Aeolis Mons (Mount Sharp)](/source/Aeolis_Mons), in [Gale crater](/source/Gale_(crater)) on the planet [Mars](/source/Mars). The approximate site coordinates are: [4°35′S 137°26′E / 4.59°S 137.44°E / -4.59; 137.44](https://geohack.toolforge.org/geohack.php?pagename=Rocknest_3&params=4.59_S_137.44_E_globe:Mars).

The rock was encountered at [Rocknest](/source/Rocknest_(Mars)) by the [*Curiosity* rover](/source/Curiosity_rover) on its way from [Bradbury Landing](/source/Bradbury_Landing) to the Point Lake overlook while traveling toward [Glenelg Intrigue](/source/Glenelg%2C_Mars) in October 2012. The rock measures about 10 cm (3.9 in) high and 40 cm (16 in) wide and was a target of the [ChemCam](/source/Chemistry_and_Camera_complex) and [APXS](/source/Curiosity_rover#Alpha_Particle_X-ray_Spectrometer_.28APXS.29) instruments on the [*Curiosity* rover](/source/Curiosity_rover).[1][2]
