Space Sunday: celestial harmonics, breathing air and singing for Pluto

July 14th: Jupiter with Io, Europa and Ganymede as seen by Juno after the craft had finished its critical orbital burn to slip into a 53.5 day orbit around the giant planet

The banner image, captured by NASA’s Juno spacecraft, might look like the one I used in my last Space Sunday update, but there is one important difference. The images used last time around had been captured by Juno on June as it approached the Jovian system on June 29th, five days before the craft had to complete a critical engine burn whilst almost scraping the planet’s cloud tops, to place itself in an extended orbit around Jupiter. The image above was captured on July 10th, as Juno headed away from Jupiter, having successfully completed the manoeuvre.

At the time the picture was captured, 17:30 UTC on July 10th, 2016, Juno was already  4.3 million kilometres (2.7 million miles) distant from the planet, and heading away from it at a relative velocity of 18,420 km / hour (11,446 mph) and decelerating under the influence of the Jupiter’s gravity.

Juno’s imaging system – JunoCam – had, along with other major systems aboard the craft, been shut down prior to the July 4th engine burn, both to conserve power – Juno had to turn its solar panels away from the Sun during the burn manoeuvre, limiting the available electrical power – and to protect them through the initial passage through Jupiter’s tremendous radiation fields. It wasn’t until July 6th that the instruments were all powered back up, and after testing them, the July 10th exercise was the first opportunity to have a look back at the Jovian system.

Juno will keep travelling outwards from Jupiter until the end of July, slowing to a relative velocity of just 1,939 km/h (1212 mph), before it starts to “fall” back towards the planet, making a second close flyby on August 27th. At this time, the craft will pass just 4,142 km (2,575 mi) above the Jovian cloud tops at a speed of 208,11 km/h (129,315 mph). More importantly, all of vehicle’s science instruments will remain powered-up, and JunoCam in particular should gain some stunning images of Jupiter during this second close pass.

To celebrate Juno’s arrival around Jupiter, NASA released a time-lapse video of the Jovian system as seen by the approaching spacecraft. It begins on June 12th with Juno 16 million km (10 million mi), and ends on June 29th, when JunoCam was shut down and Juno was 4.8 million km (3 million mi) distant.

Made possible by Juno’s high angle of approach into the Jovian system, it is the first close-up view of celestial harmonic motion we’ve ever had. Also, the 17-day duration of the movie means we see Callisto (flickering very faintly) make a full orbit around Jupiter, and get to see Ganymede, Europa and Io (counting inwards towards the planet) each experience eclipse as they pass through Jupiter’s shadow. Note that the flickering exhibited by the moons is an artefact of JunoCam, which is optimised to image bright features on Jupiter, rather than capturing the (relatively) dim pinpoints of the distant moons as they circle the planet.

Curiosity Resumes Operations as 2020 “Sister” Takes Shape

In my last update I reported that NASA Mars Science Laboratory, Curiosity, had entered a “safe” mode on July 2nd.  On July 9th, the mission team successfully recovered the rover from this safe mode – a precautionary state the rover will set for itself should it detected an event which could damage its on-board systems – and then subsequently returned Curiosity to a fully operational status on July 11th.

The cause of the problem lay in  a glitch in one of the modes by which images are transferred from the memory in some of the rover’s camera systems to its main computers. This generated a data mismatch warning, prompting the rover to active its “safe” mode and call Earth for assistance. Use of this particular data transfer mode between the identified camera systems and the computers is now being avoided in order to prevent a repeat of the problem.

Meanwhile, NASA’s next rover mission – designated Mars 2020 at present, as it will launch in the summer of that year to arrive on Mars in February 2021 – is taking shape. The basic vehicle will be based on the Curiosity class of rover, but will carry a different science suite and have somewhat different capabilities.

In particular, the new rover will carry an entirely new subsystem to collect and prepare Martian rocks and soil samples which can be stored in sample tubes. About 30 of these sample tubes will be deposited at select locations, so that they might be collected by a possible future automated mission and returned to Earth for direct analysis for evidence of past life on Mars and possible health hazards for future human missions.

Two science instruments mounted on the rover’s robotic arm will be used to search for signs of past life and determine where to collect samples by analysing the chemical, mineral, physical and organic characteristics of Martian rocks, while a suite of advanced camera systems will be housed on the vehicle’s mast. As with Curiosity, Mars 2020 will carry a comprehensive meteorological suite for monitoring the Martian environment and weather, together with a ground penetrating radar system for determining what is going on under the rover’s wheels.

The Vordun: a new art experience in Second Life

Saturday, July 12th witnessed the opening of The Vordun Museum and Gallery, created and curated by Jake Vordun, the owner of Fancy Decor.

Occupying a large, modern building on one side of the Fancy Decor region, the museum and gallery presents a venue capable of supporting multiple exhibitions, with two art exhibits and a museum exhibition being presented for the opening season. Together they make for a unique and immersive visit.

The Vordun: European Masters

The Vordun: European Masters: 300 Years of Painting

The first of the art exhibitions is European Masters, 300 Years of Painting, which occupies the main gallery hall. On displays are over 30 paintings from the period 1500 through 1799, all of which are presented in a scale consistent with one another and to their physical world originals.  These can be freely perused and admired, title cards alongside of each one offering information on its provenance:  artist, title, year of painting, medium and the physical world collection where it current resides.

However, what makes this exhibit unique is that it has an associated experience. On entering the gallery lobby, visitors should be asked to accept the gallery’s experience, smartly scripted by Tangle Giano of Madpea fame (if the dialogue is not displayed, click one of the racks of headsets on the lobby counters). Accepting it will attach a HUD and explanatory note card to your screen. The card can be clicked away once read (and the permissions requested by the experience are automatically revoked and the HUD removed & deleted on leaving the gallery area / teleporting away from the region).

The Vordun: European Masters

The HUD comprises a numbered keypad and display screen, each of the numbers corresponding to a number displayed in the lower right corner of the title card for 28 of the displayed paintings. When standing in front of one such painting, clicking the corresponding number on the HUD will focus your camera directly on the picture and display additional information (courtesy of Google Culture and Art) in local chat. An audio reading of the same text is also given for those with local sounds enabled, while the provenance information for the painting is displayed in the screen area of the HUD. Once the audio track has finished, control of the camera is released, allowing individual paintings to be more freely admired.

This approach adds considerable immersive depth to the exhibition, offering something of an audio tour of the paintings on display, whilst allowing visitors to freely wander between them in an order of their own choosing.

The paintings themselves are superbly reproduced, and run from portraits of famous figures of the times, through still life scenes, landscapes, allegorical paintings and biblical scenes. All studiously avoid the use of Full Bright, and this coupled with the use of a neutral windlight settings for the region, allows them to be presented in as close to “real world” lighting conditions as possible, further enhancing the immersive feel of the exhibition.

The Vordun:: Lip Service by Celeste Forwzy

The Vordun: Lip Service by Celeste Forwzy

The north wing of the gallery houses the second art exhibition, entitled Lip Service. Running through until September 19th, it features a set of watercolour drawings of female mouth – or specifically lips – by physical world and Second Life artist Celeste Forwzy.

Twelve framed images are presented in the exhibit, and again considerable care has been taken in their presentation. The gallery space is rendering in a neutral white, with a simple wooden floor, with each drawing softly lit through the use of a projected light. The result is and environment ideally suited to focusing one’s attention on the drawings, each of which is extraordinarily attractive.

The Vordun: A Night to Remember

The Vordun: A Night to Remember

Across the hall, in the south wing, is A Night To Remember (from the 1958 film of the same name), curated by Emery Milneaux. An interactive exhibition commemorating the loss of RMS Titanic on the night of April 14th 1912, it runs through until October 9th, and is another extraordinary piece.

On entering the exhibition space, visitors are asked to attach a boarding pass to their screen. This bears the name of an actual passenger aboard the Titanic, with the promise that the fate of the passenger will be revealed further into the exhibition. From here, visitors move through a series of rooms which take us through Titanic’s brief history, from construction to loss.

The Vordun: A Night to Remember

The Vordun: A Night to Remember

This is told through a richly mixed medium of interactive photos and title cards (click the former to focus your camera on the photo, click the latter to receive further information in chat), together with principal figures from the liner’s story: Commodore Edward Smith, the Titanic’s Captain, socialite Madeleine Astor, first class passenger and survivor, Frederick Fleet, one of the vessel’s lookouts on the fateful night, and a young newspaper boy in London, Ned Parfett. Bump into any of them, and they will present a short “first hand” narrative. There are also reproductions of the ship’s Grand Staircase, together with a first and third class cabin – the latter two starkly outlining the massive class divide of Edwardian society.

However, it is the final gallery of this exhibit which is the most poignant, dealing with the liner’s sinking. In particular, in the final room, three large plaques list the names of every passenger who sailed with the Titanic, together with their fate on the night of April 14th. Through these, visitors can discover the fate of the person named on their boarding pass, adding something of a personal dimension to the exhibition. A fourth plaque commemorates the liner’s crew, 700 of whom (out of 916) lost their lives.

The Vordun: gift shop

The Vordun: gift shop

Individually, any one of the exhibitions at The Vordun would be more than worth visiting. Taken together, and a visit becomes a singular experience of many facets, one I have no hesitation in recommending. And I’ve not even covered the gift shop, which offers copies of the drawings, paintings and memorabilia for sale, together with a range of other souvenir items.

My congratulation to Jake and all involved in the project for developing such an outstanding venue. I look forward to making many future visits to The Vordun, and seeing future exhibitions, and the use of capabilities like Experience Keys might be further leveraged.

13:30: Tea Time at Baker Street

Tea-time at Baker Street returns for the summer, featuring a new location – 221B Baker Street at the University of Washington in Second Life, and a return to His Last Bow.

A 1917 anthology of previously published Sherlock Holmes stories by Sir Arthur Conan Doyle, the volume originally comprised seven stories published by The Strand Magazine between 1908 and 1917. However, later editions of the book saw an eighth story included, The Adventure of the Cardboard Box, originally published in 1892. This week sees Holmes and Watson engaged upon  The Adventure of the Red Circle.

Mrs. Warren, a landlady, visits 221B Baker Street with what she feels is a worrying situation. She has recently rented out a room to a young bearded man who speaks accented English. He paid twice the going rate for the room – but on the condition he has it on his own terms.

However, after going out on the evening he rented the room, only to return well after everyone else in the house had gone to bed, the young man has not been seen since. He appears to be in the room, but all communications – such as requests for The Daily Gazette newspaper to be placed outside the room each morning – have been via written notes. Holmes quickly deduces that whoever is occupying the room, it is not the man who first rented it and that the key to the mystery lies within the Gazette’s agony column.

The game is then well and truly afoot when Mrs. Warren returns with news that her husband had been kidnapped, only to be dumped unharmed at the roadside. Realising that the kidnapping is a case of mistaken identity, Holmes insists he and Watson visit Mrs. Warren’s house to determine the identity of the secret lodger …

Monday July 18th To the Vanishing Point

vanishing pointGyro Muggins returns with his Monday Night treat of sci-fi, starting with Alan Dean Foster’s To the Vanishing Point.

When Frank Sonderberg insists his family make their annual vacation a road trip, his wife and kids are less than impressed. When he pulls over to the side of the road to pick up a beautiful young hitch-hiker apparently stranded in the desert, his wife definitely isn’t impressed.

But no sooner has the young woman, calling herself Mouse, boarded their motor-home than reality changes – and not necessarily for the better.  Mouse, it turns out, is an alien on a mission and in picking her up, the family is inextricably joined with her in that mission. The universe, with all its many realities, is coming apart because the Spinner, the creator of those realities, has a headache. Mouse has the cure, but in order to give it, she must reach the Vanishing Point – and she need the Sonderbergs to get her there.

Tuesday July 19th, 19:00: Blueberry Summers: Growing Up at the Lake

Kayden Oconnell reads from Curtiss Anderson’s classic coming of age memoirs.

BlueberryBorn in 1928 in Minneapolis, Curtiss Anderson grew up in an extended family of Norwegian-Americans, among whom the highlight of the year was time spent among the lakes of northern Minnesota.

For young Curtiss, growing up in the 1930s and 1940s, these were especially idyllic years. Time spent in the farmhouse among this extended family presented an opportunity for him to escape the strained and troubled relationship he had with his parents and enjoy the company of others, aunts and uncles, the loving care offered by family friends Leigh and Clara, the companionship of the family dogs – and the chances to experience young love of his own.

Through the tales he relates of these summers, so Anderson also explores the notes and letters he wrote as a boy, carefully produced on a hand-me-down typewriter. Missives and notes which, although he never realised it at the time, were in fact his first forays into what would blossom in his adult life into a distinguished career as a writer, editor and publisher.

Wednesday July 20th 19:00: Ollie’s Odyssey

OllieCaledonia Skytower reads William Joyce’s children’s tale about Oswald (or Ollie, or Oz), a stuffed rabbit and favourite of young Billy. Oz goes everywhere with Billy, until one day, he is accidentally left under a table during a wedding, and is kidnapped by the wicked Zozo.

An unwanted amusement park prize, Zozo hates all toys that are favourites; so much so that he doesn’t just want them lost – he wants them forgotten by everyone – and he has gathered other embittered toys to his cause.

Now Oz must work to not only rescue himself and get back to Billy, he must ensure all the other “lost” toys reach safety.
