Those poor objects stuck in size between asteroids and true planets.

And this image is exactly why New Horizons is on its way!

While Hubble's imagery is too fuzzy to help with determining surface features, the images still reveal the overall color of Pluto. It seems to vary from white to black to orange.

The New Horizons spacecraft is now between the orbits of Saturn and Uranus, and is in fact slightly closer to Pluto than it is to Jupiter. It is expected to passes the orbit of Uranus on 18 March 2011.

The Ralph imager on New Horizons got an impromptu test on 23 June 2006 when the spacecraft passed by (but still over a thousand kilometers away) tiny asteroid 2002 JF56.

The Great Flood of 2016 has caused a terrific amount of grief (and physical damage) to the HRPO service area. At least three personnel have received water in their homes, and I realize every HRPO patron knows someone who has water damage on his or her property.

The Highland Road Park Observatory will return to its regular schedule on Monday. There will be no evening program offerings this weekend. However, HRPO will be open tomorrow from 9am to 6pm.

From 10am to 12pm tomorrow Science Academy will take place. The topic will be "Dwarf Planets". There will be a total of sixteen slots available for Cadets eight- to twelve-year-olds. Parents/guardians can stay or drop off the participating Cadets. The cost is five dollars per in-parish Cadet and six dollars per out-of-parish Cadet.
