Over a Billion Miles – A Journeys End for Juno

I’ve been travelling a lot this past few months hence the radio silence. But one radio event that has come into view albeit on a more cosmic scale is the latest news that Juno NASA’s Jupiter mission probe is entering its last phase of an extremely long journey.  So I’d thought I’d dedicate this next post to a subject that is close to the title of my blog and draw on the analogy this brings.

We can only wonder at the immense feat this has accomplished.

 

Over half a solar system away, NASA’s $Billion Juno space probe is getting ready to fire its breaking rockets in a final push to enter Jupiter’s orbit on a day that has become popular for spaceflight landmarks — the 4th of July. Juno’s five-year, nearly 2 billion mile journey is expected to come to an end just like other missions that have shared special events on America’s Independence Day, like the touchdown of the Mars Pathfinder in 1997 and a comet collision as part of the Deep Impact mission in 2013.
…………………
The Juno mission is designed to peer beneath Jupiter’s thick clouds and to see what’s inside. That, in turn, may yield clues to how our entire solar system came to be. “It formed first, so its formation, its gravity, will have affected the other planets as they formed,” Juno Project Scientist Gary Levin told USA TODAY. This is not NASA’s first visit to Jupiter. Besides several flyby missions, the Galileo spacecraft studied Jupiter and its moons from 1995 until 2003. But Galileo avoided getting too close to Jupiter’s intense, electronics-frying radiation. Juno’s mission is focused entirely on Jupiter itself — no moons – and takes a much more dangerous approach. The mission’s vicinity will allow Juno to measure Jupiter’s gravity, magnetic field, and microwaves, which scientists can use to determine its composition.
………………….
One of the most intriguing questions is whether Jupiter is entirely gas or has a solid core deep in its center.“Right now our best theorists think that deep inside Jupiter … is this dense core somewhere between three and twenty times the mass of earth.
We have no direct evidence at all,” says Levin. Juno’s gravity readings should help confirm or refute that theory. Juno’s measurements should also allow scientists to estimate the amount of water on Jupiter and shed new light on how the planet was formed. “The water all by itself will tell us a lot about those theories of formation because if it formed from clumps of ice you’re going get a different amount of water than if it formed from the same cloud of dust that formed the sun,” Levin says.Although Juno is the second craft to orbit Jupiter, its design is quite different from the earlier one. For one, to address the dangers of dipping inside the radiation belts, the engineers built a titanium vault to shield the spacecraft’s electronics. 
…………………..
Juno’s flight plan will take it though a complex pattern of elliptical orbits that dive beneath the belts, but quickly reemerge, limiting the exposure to once every two weeks.Another mission first is Juno’s massive solar panels. Jupiter’s distance from the sun—nearly five times that of earth—means Juno only receives a small fraction of the solar energy available to Earth satellites. Engineers were forced to build huge panels to capture enough energy to deliver what is still a modest amount of power. Power being the operative word as the craft has to slow down from travelling 168,000 mph to close to Mach 2.
………………….
Imagine experiencing the breaking G force on that ..at our earths gravity level. Beyond comprehension!!!! As stateside people get ready to celebrate with their pyrotechnics maybe the best fireworks this 4th of July will be in Jupiters orbit, 365 million miles away. But all you space buffs out there will have to be patient. As all the images and footage from Junos’ cameras will take some time to reach us here on planet Earth. For one I’ll be looking forward to seeing Jupiters Aurora’s in all their glory. I wonder how they compare to the lightshow so evident in our own Northern Hemisphere.

To all you reaching for the stars and fulfilling your life’s potential.

To the next

Tallest Lift on The Planet

It appears like a special effects design out of a Star Wars epic.
But engineers have drawn up plans to build an elevator that would lift astronauts and their craft 12 miles into the Stratosphere.
The idea is that they would take off at higher altitudes there-by burning about 30% less fuel than at ground level cutting costs significantly for manned space flight.
The firm Thoth Technology Inc ( http://thothx.com/ ) has been granted US & UK patents for its “space elevator” which would travel at 7mph up a freestanding tower.

It’s an important breakthrough because…

In the patent the firm explains that blasting off from the ground requires vast amounts of kinetic energy because the propulsion systems are weighed down with fuel and must counter atmospheric drag.

When using their new design at higher altitudes less “expulsion mass” exists working against gravity and lower ascent speeds can be achieved with less fuel in the stratosphere as drag is vitually elimated .

Conventional rockets take off vertically – shedding various modules as they get higher before turning horizontal to enter space. The elevator would eliminate this stage altogether with take offs from a launch pad flying off horizontally. Space planes will launch in a single stage to orbit, returning to the top of the tower for refueling and reflight.

Mind blowing and exciting stuff which will herald a new era of space transportation.

These are the topics I want to discuss in our mastermind group. Please opt in and strike up a conversation. Any Space Junkies out there that want to explore some new ideas?

 

Success is yours for the taking

Brain Cells & Expanding Galaxies

According to a study published in Nature’s Scientific Reports recently , the universe may be growing in the same way as a giant brain – with the electrical firing between brain cells ‘mirrored’ by the shape of expanding galaxies.

The results of a computer simulation suggest that “natural growth dynamics” – the way that systems evolve – are the same for different kinds of networks – whether its the internet, the human brain or the universe as a whole.

Did you know that inside your body if you look at brain nerves endings  under the microscope and observe the colourful patterns that appear,  you can find structures and features that look strikingly like celestial bodies – millions of light years away? The universe is just as alive and complex as we are, in some ways…

  = 

 

Past studies by Dmitri Krioukov, a physicist at the University of California San Diego, showed brain circuits and the internet  look a lot alike & are not too disimilar in function. But despite finding this similarity, nobody had developed equations to perfectly predict how computer networks, brain circuits or social networks  grow over time,

Using Einstein’s equations of relativity, which explain how matter warps the fabric of space-time, physicists can retrace the universe’s explosive birth in the Big Bang roughly 14 billion years ago and how it has expanded outward in the eons since.

So Krioukov’s team wondered whether the universe’s accelerating growth could provide insight into the ways social networks or brain circuits expand.

The remarkable thing about this is that when the team compared the universe’s history with growth of social networks and brain circuits, they found all the networks expanded in similar ways: They balanced links between similar hubs with ones that already had many connections. For instance, a dog lover surfing the Internet may visit sites such as Google or Bing, but will also browse other websites or YouTube  dog Videos. In the same way,  neighbouring brain cells  like to connect, but neurons also link to such “Google brain cells” that are hooked up to loads of other brain cells.

The eerie similarity between networks large and small is unlikely to be a coincidence, Krioukov said.

“For a physicist it’s an immediate signal that there is some missing gap of understanding  of how nature works,”

It’s more likely that some unknown law governs the way networks grow and change, from the smallest brain cells to the growth of mega-galaxies, Krioukov said.

“This result suggests that maybe we should start looking for it,” he said

And the coolest thing about this is.. The Law of Attraction – could it really work ..is it as real as certain gurus suggest and is there a background science in another dimension that explains why certain events whether personal or global take place.

Could it be that  when you can harmonize with the universe..things start to happen for you in the right order.

We’re made of the same stuff as the rest of the universe, and this just shows how close we resemble the cosmos: We’re all made of star stuff.

One to ponder over..Discussions welcome.

 

Best
