Today"s a very historical day for mankind. #NewHorizon makes it to #Pluto -- we"re in for a treat... - http://clapway.com/2015/07/14/new-horizons-finally-reaches-kuiper-belt-pictures-of-pluto-on-their-way-234/

As of Tuesday, July 14th, 2015, NASA’s New Horizons mission has achieved a fly-by of Pluto, capturing images that excited so many people as it marks not only an important historical event, but also may segue Earth’s space programs into a new age of discovery and exploration. Pictures of Pluto that the spacecraft has captured will reach NASA mission control one Wednesday the 15th around 12 pm EST. Set your alerts.


Astronomical Revelations


NASA has already received a few images from New Horizons, but more and better pictures of Pluto will enlighten scientists even more. With the ones already back on Earth, though, it can be seen that there are several markings and dark spots on the surface.

These may be due to Pluto’s thick atmosphere creating mirages, so scientists are holding off on confirming what these spots and markings are. However, some have said that they look similar to other markings that can be found in our very own solar system. Experts suggest that they appear similar in structure to impact craters or even volcanoes based on the circular markings on the current pictures of Pluto.


It should be noted that the New Horizons’ trajectory has it flying past Pluto at a mere 6,200 miles (~9,978 kilometers), so while the craft isn’t landing on the planet, it is getting incredibly close and will yield pictures of Pluto that give scientists brand new information that will shatter expectations from the scientific community.


This Day is Marked in History


On this day, July 14th, 2015 every planet in the solar system has been explored at least once by a space probe.


Astronomers will finally have detailed information about every planet and know exactly what each one looks like. In a video posted to Facebook, the world-renowned theoretical physicist Stephen Hawking expressed his congratulations to everyone involved in the New Horizons mission, “The revelations of New Horizons may help us to understand better how our solar system was formed. We explore because we are human, and we want to know. I hope that Pluto will help us on that journey. I will be watching closely, and I hope you will, too.”


The ashes of the man who first found Pluto back in 1930 were on New Horizons and were launched onto Pluto. Clyde Tombaugh made great strides in the field of astronomy, and now he will rest for eternity on his most prized discovery.New Horizons Finally Reaches Kuiper Belt, Pictures of Pluto on their Way - Clapway


What We’ve Already Learned


Without having all of the photographs, scientists have already realized information they had not previously known. Because of the first set of new pictures of Pluto, scientists are theorizing that the planet may have preserved some cosmic ‘fingerprints’ from the beginning of the solar system from nearly 4 million years ago.


There is also evidence that Pluto and its moons were formed from the cataclysmic collision of two larger cosmic bodies. This is similar to a theory of how Earth and its moon were formed from the original body that Earth once was and the similar in size but now absent Theia.



An amazing historical day for space. Why wouldn’t you want your youngsters to become Space Scouts today?:

Learning more and more about #dwarfplanet #Pluto. - http://clapway.com/2015/07/13/pluto-is-bigger-than-previously-thought-245/

A briefing by mission control for the New Horizons mission held on the morning of Monday, July 13th at the John Hopkins Applied Physics Laboratory has stated that they are now much more confident of the diameter of Pluto. On the now dwarf planet that was stripped of its planet-hood in 2006, they are saying its size is larger than what was once thought.


Pluto’s Real Measurements


New pictures taken by NuSTAR reveal that Pluto is bigger and now measures around 1,473 miles (~ 2,370 km) in diameter with a margin error of 12.4 miles (20 km). Its previous measurements were around 1,472 miles (~ 2,368 km) in diameter with the same error accounted for. Because the margin of error is the same for both of the measurements, because the most recent one is bigger, it is a confirmation that the “dwarf planet” is bigger than what was originally calculated. Though the previous measurements were off by only about one mile (~1.61 km), the mass has stayed the same, meaning that the known density of Pluto changes dramatically.


What This Changes


As of right now, the density of Pluto changes, therefore changing the previous assumptions to permit for that loss. This means that much of the information that scientists “know” about the planet must change because it is bigger than previous estimates. One possibility that Alan Stern, the principal investigator on the matter, proposes is that there is more ice and less rock on the planet than what was assumed.


The Current Confirmations of New Horizons


At this time, with the new measurement of Pluto, the dwarf planet is confirmed to be the largest object in the Kuiper Belt, the ring of space debris at the outer edges of our solar system. Just because Pluto is bigger than any other known object in the Kuiper Belt does not mean that it’s the most massive or ‘heaviest’. That title goes to Eris, which was in fact another dwarf planet that helped strip Pluto of its status as a full-fledged planet.


Because this is man’s vicarious foray into “the final frontier”, there is no telling what could be found. Other larger objects may be found, thus taking the titles from both Pluto as well as Eris. Every new discovery that humanity makes–especially concerning space–leads it towards the future and a more definite understanding of the earth and other worlds alike.
