Rosetta crash-landing ends historic comet mission

https://au.news.yahoo.com/thewest/a/327 ... esa/#page1

AFP on September 30, 2016, 11:57 pm
Darmstadt (Germany) (AFP) - Europe's pioneering Rosetta spacecraft dramatically concluded its 12-year odyssey Friday, crash-landing into the comet it orbited and probed for two years in a quest to demystify the Solar System's origins.

Rosetta made a "controlled impact" with Comet 67P/Churyumov-Gerasimenko at 1041 GMT -- the closing chapter in a trailblazing project approved in 1993 to look some 4.6 billion years back in time.

Comets are thought to contain primordial material from our planetary system's birth, preserved in a dark space deep freeze.

Rosetta had been programmed to touch down at a human walking pace of about 90 cm (35 inches) per second, after a 14-hour freefall from an altitude of 19 kilometres (12 miles).

It joined long-spent robot probe Philae on the galactic wanderer's rocky, cold surface for an eternal journey around the Sun.

Confirmation of the mission's end came at 1119 GMT, when the spacecraft's signal -- with a 40-minute delay -- disappeared from ground controllers' computer screens.

"We have loss of signal of Rosetta," announced a grim-faced Lodiot.
"We will be listening for a signal for another 24 hours, but don't expect any..."

Biggest 'supermoon' of the century set to light up the sky

https://au.news.yahoo.com/thewest/a/330 ... ars/#page1

Step outside and take a look at the Moon, it’s going to be ‘super’.

That’s the advice officially issued by NASA as the world prepares to be visually wowed by an awe inspiring ‘supermoon’.
On November 14, the most super of ‘supermoons’ will rise sending star gazers into a virtual tailspin of astrological excitement.

And according to NASA no matter where you are located in the world, you'll be able to see the ‘supermoon’, providing the weather behaves.
On November 14 the Moon will be the closest to Earth (called perigee) it has been in the 21st century, as it orbits the planet.
The full Moon won’t come this close again to earth until November 25, 2034.

The last time the Moon was that close to Earth was January 1948.
It's expected the Moon will appear about 30 percent brighter and 14 per cent larger.

"This month’s is especially ‘super’ for two reasons: it is the only supermoon this year to be completely full, and it's the closest moon to Earth since 1948, when a gallon of gas cost just 16 cents," NASA said in a statement.

"The Moon won’t be this super again until 2034."

‘Supermoons’ are made possible due to the fact that the Moon’s orbit around Earth isn't perfectly circular.
When the Moon is at its closest point to our planet, it's actually about 30,000 miles closer than it is at apogee.

“The term supermoon has entered popular consciousness in recent years,” according to NASA.

“Originally a term from modern astrology for a new or full Moon that occurs with the Moon is within 90% of its closest approach to Earth in a given orbit, supermoon now refers more broadly to a full Moon that is closer to Earth than average.”

NASA has also announced another supermoon can be expected on December 14 however this one will be “remarkable for a different reason”.
They have stated: ”it’s going to wipe out the view of the Geminid meteor shower.”

Either way both instances are expected to remarkable and visually stunning.
May you be in heaven half an hour before the devil know`s you`re dead!

It wasn't bad last night either....directly to the west of my place around 0300. We are lucky as clear skies throughout the country except far south from what I can see on the weather maps. Pete :cheers:

I took this earlier from the balcony of the place I'm currently staying at in Hua Hin. I got closer shots as well, but without a tripod, really struggled with camera shake.

Hey we have the same moon over here, but it's a different color...

:D

I'm sure there must be a simple reason to explain the various moon colour's! More here:

I never really thought about it before but looking at the two close ups of the moon above I was actually a bit surprised that it is nearly an identical view of that body from opposite sides of the earth. I guess the moon does not spin??? It always stays facing the earth the same way so that we never see "the dark side". I always thought the dark side was whatever side was facing away at the moment, but apparently the dark side is static.

Also, in researching that, I realized that while I always thought the moon orbited the earth, but according to this it doesn't...

"The Moon Does Not Orbit the Earth!"

http://beforeitsnews.com/space/2013/08/ ... 63988.html

Then there is this...

"Does the Moon Orbit the Sun or the Earth?"

:? :? :?

It's not a dark side. It's the side facing away from the earth. The moon has a night and day cycle just like the earth, except the cycle takes approx 28 days - a lunar month. But then, you all knew that.
