To infinity and beyond

Things are a tad quiet on the Mars news front, with Curiosity still on walkabout in the “Pahrump Hills”. So here’s a little round-up of some upcoming NASA news.

Orion Countdown

Thursday, December 4th should see the first launch of NASA’s next generation crewed space vehicle, the Orion Multi-purpose Crew Vehicle (MPCV). Superficially harking back to the days of the Apollo Moon landings, Orion is a two-stage vehicle comprising a capsule-like Command Module, capable of seating up to 6 astronauts, and a smaller Service Module, which supplies propulsion, power and life support. However, Orion is a lot more sophisticated than the Apollo craft, the capsule unit being a lot larger in both size and volume, and having the capabilities of both being reused and of making either a splashdown or landing on dry land on its return to Earth.

As I’ve previously reported, this first launch of Orion will be uncrewed, serving to test the vehicle’s launch, flight and recovery capabilities in a mission lasting some 4.5 hours which will take the craft further from Earth than has been the case for any crewed vehicle since the last of the Apollo lunar missions in the 1970s. In doing so, the vehicle will be tested through the Van Allen radiation belts surrounding the Earth, and the capsule will be directed to re-enter the Earth’s atmosphere at around 80% of the velocity it would achieve on a return from a cislunar mission (that is, roughly 4,000 kp/h (2,500 mph) faster than the space shuttle ever returned to Earth).

Orion is designed to sit at the hub of NASA’s plans for the initial human exploration of the solar system. Its likely future uses include ferrying crews to the Moon and back and, in the 2030s, forming the command vehicle in a human mission to Mars.

For lunar missions, Orion will, again like Apollo, be mated to a lunar lander, which it will ferry to the Moon, before the crew transfer to the lander and descend to the Moon’s surface. Again, the differences are that with the Orion mission, the MPCV can remain “parked” in lunar orbit unattended while the crew use their lander and equipment and facilities landed remotely on the Moon to spend weeks or Moons there, rather than days.

For missions to Mars, Orion will be part of a much larger vehicle, the details of which are still to be decided, but which is likely to be launched by Orion’s dedicated rocket, the Space Launch System (SLS), in a number of parts which will rendezvous in orbit prior to the crew flying to it via Orion and embarking. An Orion capsule would then serve as the Crew Return Vehicle, delivering the crew back to Earth at the end of there 3-year mission.

Orion’s first mission will use a fully-functional capsule mated to a “dummy” service module (the actually service module is to be built by the European Space Agency, using the technologies developed in the hugely successful but grossly under-sung Automated Transfer Vehicle design, which has been quietly resupplying the International Space Station for the last five years (and refuelling it) with up to 7 tonnes of supplies per flight – more than double anything managed by the Russian Progress supply vehicles, the SpaceX Dragon and Orbital Science’s Cygnus vehicle.

In 2017, Orion will make an unmanned flight around the Moon (shown in the video below), this time using an actual Service Module and the SLS launcher, in what is being called the Exploration Mission 1. Then, in around 2021, Orion will fly its first crew in a mission to rendezvous and land on an asteroid.

New Horizons to Wake-up

Assuming all goes according to plan, two days after the Orion test flight, over 26 AU from Earth (AU being an astronomical unit – the average distance between the Earth and the Sun – that’s 149,597,871 kilometres or 92,955,807 miles), a tiny space craft will “wake up” from the third of three hibernation periods which have collectively lasted 31 months, allowing it to ready itself for its primary mission objective: a 6-month “flyby” of the dwarf planet Pluto, which should yield masses of information about that world and its major companion Charon.

after 10 years in space – the last 31 months of which have been largely in hibernation (other than brief periods of science data gathering), and a voyage through our solar system which has, like that of ESA’ comet-chasing Rosetta mission – provided many other opportunities for science discovery, New Horizons will commence its primary mission in January 2015, as it starts into its approach and fly-past of Pluto, Charon and their family of tiny “moons”, Kerberos, Styx, Nix and Hydra.

No-one actually knows what New horizons will reveal; such is the distance between Earth and Pluto, we know very little about it in real terms, so the mission is very much like those of the pioneering days of space exploration, when we sent vehicle to Venus and Mars, not actually knowing for sure what they’d find.

Despite travelling at 1,600,000 kilometres a day, it will take New Horizons until July 2015 to reach its point of closest approach to Pluto – just 10,000 kilometres from the planet’s surface. The images and data it should return to Earth promise to be astounding.

And after July 2015? New Horizons will be heading out into deep space beyond our solar system, becoming only the third vehicle built by humans to do so, the other two being Voyagers 1 and 2. Providing it is still active, New Horizon should reach the heliosphere,  the “boundary layer” marking the divide between the solar system and interstellar space, in 2038. Between 2015 and then, the craft will be used to observe other Kuiper belt objects of interest and send back data on the space through which it is travelling.

Wanderers

Whether humanity ever joins Voyager and New Horizons in moving beyond our own solar system is a subject of popular debate. Given the distances involved between the stars, the only practical way of reaching solar systems beyond our own in through exotic methods – faster-than-light travel, wormholes, and the like – if we are to avoid centuries and generations travelling the interstellar void; and there is still no guarantee we’ll harness either.

But even should we remain locked inside our own solar system for centuries to come, we still have a vast range of environments to explore and possibly tame. This is something Erik Wernquist reminds us about in a stunning video he’s produced, using selected commentary spoken by the great Carl Sagan during his ground-breaking television series, Cosmos. This really is one to watch.

My thanks to Nalates Urriah for pointing me to Erik’s video.

A Kitten’s winterland

The end of another year draws ever nearer, and in the northern hemisphere this means thoughts turn to those of winter landscapes and cold, crisp mornings, something which tends to be carried into Second Life as well. Many regions are estates have already welcomed the soft cover of snow and winter scenes are starting to appear appear the blogsphere.

With December on our doorstep, I decided to head away to Kitten’s Heaven, Isabelli Anatine Hak’s homestead region, which offers a place for people to visit and relax and enjoy a spot of photography if they wish. Freshly remodelled for the winter months, Isabelli was putting the finishing touches to the region in its new look when I arrived, as she completed furnishing the main house.

Surrounded by icy waters which are in turn surrounded by snow-capped and dusted craggy cliffs and peaks, Kitten’s Heaven offers a picturesque scene of frost coated trees raising bare branches to the sky, under which can be found reindeer, bears, foxes – and even a penguin or two. There are skis available for those feeling active (snowboards may also be added), and a large frozen lake offers plenty of space for skating – but do mind the cats as they enjoy their own little bit of ice boarding!

A sliver of unfrozen water separates the lake from two rocky outcrops. Upon one of these sits the main house, a large Tudor-style building, reached by a rocky, snow-covered path. Here visitors will find refreshments to fortify them against the cold, and fully furnished rooms upstairs to explore. A snow-covered span of  rock bridges the gap to the second plateau, where an outdoor café offers hot soup and mulled wine to those of a hardy disposition who enjoy the bracing outdoor air.

There are numerous places to sit down and enjoy the surroundings, be in on a sleigh or next to a blazing camp fire  or in the little cottage where more of Isabelli’s love of cats can be found. As noted above, wildlife abounds, and there is also a mysterious little man with his lantern taking a peek at what’s going on – but I doubt he means any mischief!

Kitten’s Heaven always offers an eye-catching and warm welcome to visitors, and even though snow may lay heavy on the ground right now, that hasn’t changed with this make-over. So why not hop over and take a look for yourself?

Water, through a photographer’s eyes

H2O - Walt Ireton (Jay Evers)

Sometime in the early years of our planet, billions of years ago, two gases allied themselves – hydrogen and oxygen. They became a liquidity, which enabled the emergence of life on earth. Water – the basic element – the element of constant change. It all began with water and water is inside anything living. Water – the element of constant change.

Thus reads the introduction to H2O, a photographic exhibition by Walt Ireton – known in the physical world as Jay Evers – at his Sominiem Art Gallery in Tabula Rasa. Based in Hamburg, Germany and Enschede in The Netherlands, Walt’s business is creative wedding documentary and event photography. However, his passion lies within the fields of natural, street, and macro photography.

These three aspects of his photography are combined H2O, which, as the introduction and title suggest, focuses on the subject of water. On display are some 37 images taken from the physical world (four of them stunning photo montages of a single image divided into three or four parts), split across two levels of the gallery space which Walt also designed.  And believe me when I say, they are simply stunning.

“Water is very good in showing us how restricted our visual perception actually is,” Walt says of the exhibition. “Our eyes can see only a small part of the existing light [and] all information that our eyes do see, is filtered in various ways before it reaches the conscious part of our brain.

“Another aspect of water is, that it is moving most all of the time,” he adds. “A camera is capable of de-accelerated perception, which with longer exposure times makes moving water look like diffused veils or misty clouds. A vision of the primeval ocean suggests itself.”

All of which leads him to conclude that while a photograph does not really show an absolute and objective moment in time, it can nevertheless, and almost literally in the case of the natural flow and motion of water, freeze a moments in time which then themselves become timeless, literally.

And “timeless” is precisely the adjective to apply to many of the images here, from the foamed water roiling around rocks so suggestive of that primeval ocean Walt notes through to the amazing sight of the very top of a fountain plume caught in that 1/6000th of a second as it arches and twists at the start of its gravity-induced fall back towards the ground, with so many more in between – such as the reflection of a building caught in a street-side puddle, something unlikely ever to be captured in the same way ever again.

As well as the H2O exhibit, the upper levels of the gallery space (reached via the Anywhere Door on the ground level) also play host to two further exhibitions. The first is Impresiones de La Gomera, presents real life images of the island of La Gomera capture by Walt and his parter, Seoreh Voight, The second is Working Under Pressure, presents the comic book artistry of Martin Scarborough as large-format pieces.

As a final note, not only are the images displayed in H2O and Impresiones for sale at the gallery, those living it Europe can avail themselves of Walt’s website if they so wish and order copies to grace the walls of their physical world home. And when visiting Tabula Rasa, why not avail yourself of the other galleries and exhibitions in the region – including Walt’s own City Windows?
