The New Horizons team released one more picture from Tuesday's encounter, one of three high-resolution images from a mosaic that crossed the center of Charon's disk, and it took me a while to figure out what it reminded me of.
Today's press briefing at the Applied Physics Laboratory in California was preceded by hours of New Horizons team members cryptically dropping hints on Twitter at astonishing details in the seven images downlinked since the flyby. The images are, in fact, astonishing, as well as beautiful, surprising, and puzzling.
At a press briefing this morning, New Horizons principal investigator Alan Stern divulged some extremely preliminary first science results from the New Horizons Pluto encounter. Science results include Pluto's diameter and information on its surface composition and atmospheric escape.
In the span of a few days, Pluto and Charon have turned from spots into worlds. The latest images from New Horizons are showing Pluto and Charon to have unique faces, distinct from any other icy worlds in the solar system.
NASA held a press briefing today to explain the nature and cause of the spacecraft anomaly that halted science on New Horizons for four days as it was on its terminal approach to Pluto. As of the moment that I write this post, New Horizons is not yet performing science observations, but it will resume them tomorrow, July 7.
Only about three weeks remain until the flyby — it's getting really close! I almost don't want the anticipation to end. New Horizons is now getting color images and is seeing features on Charon. Deep searches have yielded no new moons.
Pluto and Charon are growing larger in New Horizons' forward view, beginning to develop distinct personalities. A version of recent New Horizons photos processed by Björn Jónsson reveals an enigmatic dark line. Our maps of Pluto's surface are now as good as our maps of Mars and Venus, circa 1900!
