China to the Moon...

Perhaps they're looking for the monolith?

Why China wants to land a spacecraft on the mysterious far side of the moon

China appears to be planning a space mission to a place no nation has ever been — the far side of the moon.
The China National Space Administration (CNSA) currently plans to launch Chang'e 4, a craft that will carry the country's second lunar rover, in 2020. According to comments recently made by Wu Weiren, the Lunar Exploration Program's chief engineer, the rover will likely touch down on the side of the moon that faces away from Earth.
"We probably will choose a site on which it is more difficult to land and more technically challenging," Wu recently told the state broadcaster CCTV. "Other countries have chosen to land on the near side of the moon. Our next move probably will see some spacecraft land on the far side of the moon."
Since 2007, China's ambitious lunar program has already placed two probes in the moon's orbit and one lander on its surface. Putting a rover on the far side could provide new data on the moon's geologic history — and demonstrate the CNSA's growing expertise in and dominance of lunar exploration.

Though China began launching satellites and conducting other activities in space all the way back in the 1970s, the country's space agency has made its biggest strides since 2000, becoming the third nation to send astronauts into space in 2003. Since then, the CNSA has focused on a destination that NASA and other space agencies have mostly overlooked as of late: the moon.
In 2007, the CNSA sent its first spacecraft — named Chang'e 1, after the Chinese goddess of the moon — into lunar orbit. That was followed by the orbiter Chang'e 2 in 2010 and the lander Chang'e 3 in 2013, the latter of which brought a small rover (called Yutu) to the moon, and became the first craft to make a soft-landing there since the 1970s.

The next few missions will go even further. Chang'e 5, to be launched in 2017, will collect a rock sample and launch it back up to an orbiter, in order to bring it back to Earth. (Confusingly, Chang'e 5 is launching before Chang'e 4 because the latter was originally built as a backup to Chang'e 3, then sat in storage for a few years and has since been retrofitted for the new mission.)
Plans call for Chang'e 4 to launch in 2020. Though Chang'e 3 successfully landed, mechanical problems prevented the rover it carried from traveling more than 100 meters. If all goes as planned, the new craft's rover will be able to gather much more data — and perhaps explore the moon's relatively unknown far side.
The mysterious far side of the moon
tidal locking
Because the moon rotates at the same rate it orbits the Earth, it's tidally locked, as shown at left — and the same side always faces Earth. If it didn't rotate, we'd see both sides equally, as shown at right. (Stigmatella aurantiaca)
From Earth, we always see one side of the moon because it's tidally locked: it rotates at the same speed that it orbits us.
As a result, we know much less about the far side (calling it the "dark side," while a bit more poetic, isn't really accurate, because it gets just as much sunlight). And because there's no direct line of sight from the Earth to the far side, landing a craft there would require all communications to be routed through an orbiter before reaching the lander.
But as difficult as it sounds, a mission to the far side would yield plenty of rewarding data. Though the moon's entire surface has been extensively photographed by orbiting probes — starting with the USSR's Luna 3, in 1959, and currently by NASA's Lunar Reconnaissance Orbiter — no lander or rover has ever documented the far side up close.

We already know the near side of the moon is covered in dark spots, which are plains of basalt that formed after volcanoes erupted billions of years ago and their lava cooled.
The far side is different: it has few dark spots and lots of craters, though scientists don't fully understand why. It may be that underneath its surface, there were never as many volcanoes, but that explanation still isn't fully proven. Chang'e 4 might tell us more, by collecting data on the rock that covers the far side's surface.
Depending on where the rover is sent, it could also provide some information on the moon's interior. The far side features the giant South Pole–Aitken basin — a huge crater in which the crust might be so thin that mantle rock peeks through. Data on this rock could help scientists better understand the layers that make up the moon.

Mantle material might be accessible in the South Pole-Aitken basin, on the southern end of the far side. (JAXA)
Finally, there's some speculation that China might be interested in visiting the moon's far side and conducting sample-return missions for an entirely different purpose: harvesting helium-3, an isotope of helium that could someday be used for both nuclear weapons and energy production.
The isotope is much more abundant on the moon than on Earth, where it's extremely rare. And the moon's far side is believed to have the highest concentrations of it, because it's exposed to much more solar wind, which deposits helium-3 in the first place.
It's not certain that this is China's goal. In order to get usable quantities of helium-3, a craft would need to harvest way more rock than Chang'e 5 will be capable of doing. The CNSA, meanwhile, has never explicitly said that it's planning on mining helium-3.
Still, Ouyang Ziyuan, chief scientist of CNSA's Lunar Exploration Program, has previously mentioned helium-3 as a long-term potential benefit of the Chang'e program. It's conceivable that one reason for returning lunar samples and exploring the moon's far side is to collect initial data needed for this sort of ambitious extraction project.

Apollo 11 and UFO Encounter...

As I promised one of my Facebook friends, i am posting the actual interview with Apollo Astronaut Buzz Aldrin, concerning the documented UFO he & his flight companions witnessed on their famous journey. It took me a minute to scare it up for your viewing. So,here it is.

Before Christ...

Hope all had a great Easter/Passover. Oh! BTW as always I have 2 b provocative. So, i'll leave u with a little Meso-American history & the reason why the Aztec natives saw no reason to adopt the Spaniard's version of the crucified Christ. As u can plainly see: THEY ALREADY HAD ONE named Quetzalcoatl for thousands of years.

Happy Birthday Marguerite!...

& on this day, 28 years ago, my daughter, Marguerite Daniele Canada was born. Here's the scoop! She was supposed to arrive April 1st (which would've made her an "April Fools" baby). But she was smarter than us & waited until 12:40 am, April 2nd to come into the world. I love you always, my dearest daughter, Marguerite. may you always be blessed!

A Must See Interview...

A marvelous interview with Dr. J. Allen Hynek on UFOs. A must see.

More Hardcore UFO Evidence...

Dr. J. Allen Hynek (past Chairman of the Astronomy Department of Northwestern University) served as the scientific consultant to US Air Force's official UFO investigation, initially the secret Project SIGN and later the well-known Project "Blue Book". He did field-investigations and talked to claimed UFO eye-witnesses for 2 decades (between 1948-1969). Starting out as a skeptic, who tried to "explain away" the phenomenon (in an attempt to explain the Michigan 1966 sightings, Hynek came up with the infamous "swamp gas" idea, which became something of a national joke), he later became convinced of the UFO reality and admitted that Project Blue Book had misled the public. His work and findings were used by Director Steven Spielberg for the movie "Close Encounters of the Third Kind."

More UFO Evidence...

Some UFO evidence with four-way confirmation: ground visual, ground radar, airborne visual and airborne radar -- as early as 1950s, watch LtCol Brown NPCC 2001 testimony, who worked in the US Air Force's Office of Special Investigations on project Grudge, the precursor to Project Bluebook. Such radar/visual UFO are considered by experts as being worth further investigation.



Testimony from Credible Witnesses...

Ufo Testimony, supported by declassified documents from the US National Archives, US Navy pilot Cmdr Graham Bethune describes the encounter with a huge 90m (300ft) discoid UFO in 1951 on the way back from a classified mission to Iceland: "We had 31 people [relief crews] on board and a psychiatrist, plus the crew. We all witnessed it"

I invite you all to check it out!
