Dragon Flies around the Moon, Giant Penguins Once Waddled the Earth, Gifts from NASA


In a gracious gesture, NASA has released free access to software featuring new technologies.
Whizz - kids and Tech-heads will find plenty of inspiration in their PDFs.
The new 'space race' is hotting up as Dragon X announce the first commercial flight around the moon taking place next year, 2018.
Two people will be undergoing health and fitness tests for the milestone journey very soon.
The ultmate goal  for Dragon X is to transport people '...to Mars '.

Even in space with its mind - boggling distances , there are near - misses: recently, the Mars Orbiter had to be course - corrected to avoid collision with Phobos.
This may sound insignificant, but I was taken aback to learn that Mars is a busy ' highway' with no less than five vehicles in orbit.
Which led me to wonder how many were in orbit around our moon , and finally Earth  ( over a thousand )
Even Saturn is being buzzed -  by our intrepid explorer Cassini, which took the photo shown below.
Cassini is currently grazing the ring system around Saturn , observing and preparing for its ultimate demise when it plunges into the gas giant in September.

Pause for jaw-dropping fact - each  pixel equates to 37 miles...
 ...that's big.
Saturn is said to be a place where metallic hydrogen exists in the crushing pressure of the atmosphere.
Regarded as a ' Holy Grail ' of chemistry, its status is due to the fact it could be potentially used as rocket fuel, which makes Saturn a re-fuelling stop on the long journey to our next destination.
Attempts have been made to replicate the material under laboratory conditions , which have allegedly succeeded, but unfortunately, the only sample of metallic hydrogen in the world has gone missing .
As you can imagine this has caused great concern.
The extra difficulty in finding the missing sample is that it is one-fifth the thickness of a human hair.
Which is pretty small.
Regardless, though, baffled scientists are currently looking behind curtains and down the side of sofas.
So far, they have found thirty brass coins, a leaky biro pen, a washer , and a ticket to a Level 42 gig .

Meanwhile, back on Earth...

The University of Hong Kong have created a computer simulation of a flying dinosaur with four wings.
Also, fossil evidence of a giant prehistoric penguin  has been found  in New Zealand.

Finally, apropos of nothing,  I found this article very interesting. 






Please note - I have been guilty of occasionally linking to articles in Wikipedia. This has been pointed out as a highly unreliable source of information, which I understand - but in my experience, simple fact - checking against alternate sources is always the way to go. I trust that others will continue to do the same, as I don't intend to patronise my readers . Thank you for being here !
