Bright spots are seen on Ceres by the Dawn spacecraft. We shall be seeing them from a lower altitude soon as Dawn lowers its orbit.

Yep Ceres has them as well. Could be outcrops of minerals, ice, or something similar. It's pretty cold out there that far from the sun!

Both Ceres and Pluto belong to the primitive part of the Planetary System. We might be in for some surprise.

Well Tullio, it's simply place your bets time isn't it? I'm guessing we won't find that anything unusual there, but maybe new yes, certainly.

I've suggested a kind of natural nuclear fission reaction, like that found in Oklo, Gabon, 1972. Wait and see.

A final correction has been made the New Horizons path to Pluto. It takes 9 hours to send a command to the spacecraft, so commnds must be sent in advance and stored in the computers to be executed at an exact moment.
Meanwhile the SOFIA 2.5 meters IR telescope aboard a 747SP modified jetliner has observed an occultation of a star by Pluto on June 29, which is important for the study of the Pluto atmosphere, which includes methane.

OMG!

New Horizons Update: Methane Detected; New Images of Pluto and Charon; Sunrise/Sunset Observations

Yes, there is methane on Pluto, and, no, it doesn’t come from cows. The infrared spectrometer on NASA’s Pluto-bound New Horizons spacecraft has detected frozen methane on Pluto’s surface; Earth-based astronomers first observed the chemical compound on Pluto in 1976.

“We already knew there was methane on Pluto, but these are our first detections,” said Will Grundy, the New Horizons Surface Composition team leader with the Lowell Observatory in Flagstaff, Arizona. “Soon we will know if there are differences in the presence of methane ice from one part of Pluto to another.”

Several recent images of Pluto show what looks like a huge crater, better than 1/2 of the planet's diameter. A dark ellipse, surrounded by a whitish rim are apparent, suggesting the contours of a crater, as seen from a low angle. An impact on this scale would very probably be enough to destroy Pluto's structure, erasing all traces of itself. If the better images that will be coming in over the next two weeks confirm that this feature is real, it may be necessary to devise another explanation for it.

On the opposite hemisphere of Pluto from the apparent huge crater, they've seen several dark, rounded areas, each of about the same size, equally spaced along the equator. The investigators are at a loss to explain these. Link below to an article with pictures of both the huge crater-like object, and the self-similar array of dark circles. Magnifying the images with your computer will help in seeing these features more clearly.

Pluto is actually the remnants of an old abandoned death star.

The New Horizons space probe nearing Pluto suffered a technical fault on Saturday. It is currently communicating with Earth, but is in safe mode, which means that no photography or other scientific work can be done at the moment. The mission team will analyze diagnostic data from the probe, to try to determine the nature of the problem. They hope to restore New Horizons to normal operations with a day or two, ahead of the Jul. 14th flyby of Pluto. Link to news article on this matter:

Some very good news, indeed, from NASA. The problem with New Horizons was quickly traced. It was caused by a timing error in a command sequence recently sent to the space probe. The error will be promptly corrected. Normal science operations are planned to resume on Tues., the 7th. It is expected that the interrupted operation of New Horizons will not have a substantial effect on the overall mission.

I really hope they have sorted out the problem(s). It would be a terrible letdown if,after all those years, they fail to get all the data that is possible to obtain during that one shot fly by.

New Horizons systems are all functioning.
The mission remains on track to conduct the entire close flyby sequence as planned, including the July 14 flyby of Pluto.

Science will be poring in for sixteen months, from New Horizons.


The map combines images takes between 27 June and 3 July

Scientists have released their latest map of Pluto, using images from the inbound New Horizons spacecraft.

It unwraps the visible parts of the sphere on to a flat projection, giving another view of the features that have started to emerge in recent days.

Evident are the light and dark patches at the equator, including one long dark band being dubbed "the whale".

The US space agency's (Nasa) New Horizons probe is now less than seven days away from its historic flyby.

It is due to pass over the surface of the dwarf planet at a distance of less than 13,000km, grabbing a mass of images and other kinds of scientific data.

The pictures at that point will be pin sharp, showing targets on the surface of the 2,300km-wide body at a resolution of better than 100m per pixel.


The spots are part of a dark band that wraps around much of Pluto's equatorial region

As of Wednesday, New Horizons was less that 7.5 million km from Pluto.
