Rosetta's 2015 stereo view of Comet 67P

Background

  • Rosetta's narrow-angle OSIRIS camera provided a stereo view of Comet 67P on July 25, 2015.
  • The stereo anaglyph combined two images taken from 184 kilometers away.
  • Comet 67P, also called Churyumov-Gerasimenko, has a jagged, double-lobed nucleus with a smaller lobe 2.5 kilometers across.
  • Jets were emanating from Comet 67P while it was near closest approach to the Sun.
  • Rosetta's mission ended in September 2016 with a controlled impact on the comet's surface.

What happened

On July 25, 2015, Rosetta's narrow angle OSIRIS camera provided a stereo view of Comet 67P from 184 kilometers away. The comet was near closest approach to the Sun, and jets were emanating. Rosetta's mission ended in September 2016 with a controlled impact on the comet's surface.

What we know

Comet 67P is identified as Churyumov-Gerasimenko and is described as having a jagged and double-lobed nucleus.

The lobes are joined by a narrow neck, and the smaller lobe is 2.5 kilometers across.

The stereo anaglyph was created by combining two images.

The camera details list Rosetta's narrow angle OSIRIS camera, a date of July 25, 2015, and a distance of 184 kilometers.

Jets were emanating while Comet 67P was near closest approach to the Sun.

Rosetta's mission ended in September 2016, when the spacecraft made a controlled impact onto the comet's surface.

Why it matters

For readers tracking the lunar industry, the facts provide a concrete example of close-range observation that ended with a controlled impact on a comet's surface. The documented date, distance, and surface-contact endpoint show the operational detail available from a completed mission.
