Space Sunday: the Sun, Moon and updates

The launch of Artemis 1, provisionally scheduled for September 23rd has been … postponed,  just days after NASA indicated the date was their preferred new target for the uncrewed mission to cislunar space.

As I noted in my previous Space Sunday update, this date and the one following it (September 27th 2022), hinged on a number of factors, including a test of the repaired propellant feed lines on the mobile launch platform which have proven to be the thorn in NASA’s paw when it comes to the first launch of the massive Space Launch System rocket.

This test had been scheduled for Saturday, September 17th. However, it was decided to push it back to the 21st to allow more time for the ground crew to have more time to prepare for the load test. Attention has therefore switched to attempting the launch on September 27th with October 2nd a provisional back-up date. However, the latter remains under review as NASA plan to launch a crew to the International Space Station (ISS) aboard the SpaceX Crew 5 Falcon 9 / Crew Dragon combination from Pad 39A on October 3rd.

A further potential hurdle for meeting either launch date is the need for the US Space Force to grant a waiver on the recertification of the Flight Termination System (FTS) – the package used to remotely destroy the rocket if it veers off-course during its ascent through the atmosphere. The request for a waiver is still being evaluated at Canaveral Space Force station; if denied, then the rocket will have to be rolled back to the Vehicle Assembly Building (VAB) so the FTS can be fully re-certified – a porcess that is liable to push any launch back until after October 2nd.

The September 27th launch window opens at 15:37 UTC for 70 minutes and presents a “long class” mission for the uncrewed Orion space vehicle, lasting 41 days, with splashdown occurring on November 5th, off the coast of San Diego, California.

NASA Requests Proposals for Additional Lunar Landers

On September 16th, NASA issued a call for proposals for a lunar lander vehicle in support for crewed lunar missions beyond the initial Artemis 3 mission – the first mission to land an American crew on the Moon since 1972’s Apollo 17 mission.

That first mission is due to utilise a modified version of SpaceX’s Starship for place a crew of two on the surface of the Moon and return them to orbit. However, the contract granted to SpaceX – which has yet to actually proceed with work on the modified vehicle in earnest – was viewed as controversial at the time it was given, being granted in the face of two far more capable – if more expensive – proposals. As a result, NASA was ordered by Congress to seek an additional lander vehicle under what is referred to as the Sustaining Lunar Development (SLD) project. Companies interested in responding to the call have until November 15th, 2022 to do so.

The call is for a far more versatile vehicle than that defined by the contract for the initial Human Landing System (HLS) contract awarded to SpaceX. It calls for a lander vehicle type capable of “sortie” style missions with crews of 2 and landing up to 25 days apiece, with the crew living aboard the vehicle. These missions will likely be “scout missions” to evaluate potential sites on the Moon where a base might be established.

The NASA NextStep HLS-SLD includes the development of the lunar gateway station orbiting the Moon and stratgies for carrying technologies developed for lunar operations for use on Mars. Credit: NASA

In addition, and supported by habitat units delivered separately to the lunar surface, the vehicle must be capable of landing crews of 4 astronauts on the Moon for up to 33 days at a time. Finally the vehicle design must be capable of automated cargo landings on the Moon in support of crewed missions.

It is not currently clear whether the two completing proposals for the original HLS contract – led respectively by Blue Origin and Dynetics – will participate in submitting proposals. Two of Blue Origin’s partners for the original HLS contract, Lockheed Martin and Northrop Grumman, have remained non-committal towards further participation in any additional lander projects since the SLD project was formally announced in March 2022.

Dynetics, however, were one of five companies to receive US $40.8 million each from NASA as a part of a 15-month initial SLD study initated in September 2021. As  a part of this work, Dynetics committed to risk-reduction activities and provide feedback on NASA’s requirements to cultivate industry capabilities for crewed lunar landing missions. Of the three original HLS  proposals, the Dynetics design – whilst the most expensive – most closely matched the requirements outlined in the SLD call and offered the advantage of being launched to the Moon using vehicles other than SLS. As such, there is some speculation they will respond to this new call for proposals.

SpaceX is excluded from responding to this new call for proposal. However, NASA indicating it plans to exercise an option in SpaceX’s existing contract and call on SpaceX to evolve is lunar Starship design “to meet an extended set of requirements for sustaining missions at the moon and conduct another crewed demonstration landing.”

Evil Under the Sun – a Seanchai Library special event

Whilst at the hotel, he encounters the other guests, notably Arlena Marshall who, desire being at the hotel with her husband Kenneth and step-daughter Linda, spends a lot of her time flirting with Patrick Redfern – much to the anger of Redfern’s wife, Christine and the disgust of her step-daughter. Also among the guests is Rosamund Darnley, who was once sweethearts with Kenneth Marshall.

Trying to keep himself apart from the intrigue, Poirot finds himself drawn into the middle of things and in need of his most particular deductive skills when Arlena Marshall is found dead on the sand of a secluded cove across the little island far from the hotel; a place where she apparently had a secret assignation…

The caves and caverns of Rosehaven in Second Life

Clair View Ruins and caves, The Realm of Rosehaven, September 2022 – click any image for full size

The Realm of Rosehaven  (operated by SelenaAnansi and Serra Anansi) is one of the oldest fantasy / medieval themed residential and role-play communities in Second Life. Totalling 15 regions, it offers a rich mix of private and public spaces, it is a place with much to see and discover; a place that can be called home by those with a focus on fantasy.

We offer you a place to hang your hat, rest your feet, and let the stress of the outside world fade away in a fantasy British Isles styled setting.  Architecture and themes are inspired by fairy tales, lore, myths, and possibly your dreams.  Medieval and fantasy clothing is welcomed and encouraged; however, there is no set dress code.
Rosehaven is a land of magic and dreams – the living embodiment of imagination and creativity, where humans, elves, fae, shapeshifters, and other creatures can peacefully coexist among the mist-covered lands.

Clair View Ruins and caves, The Realm of Rosehaven, September 2022

I was drawn to the estate after learning about the extensive network of caves, caverns, tunnels and places of mystery and magic which offer the Second Life explorer much to see and – well, explore.

This is a network with many points of entry (and exit!), which exists underground, under the sea and in the air, the various elements linked by an experience which allows for relatively seamless teleport movement between locales. Given the multiple points of entry, how and where a traveller may come by the system is a part of the fun of discovery; it might be a case of noticing a shadowed archway between houses and then walking through it, or finding a ladder leading down into the bowels of the earth from the basement of a public building, or even the ornate doors at the foot of a cliff which open at the touch of a hand rather than the utterance of “Mellon!

Clair View Ruins and caves, The Realm of Rosehaven

For the purposes of my explorations, I opted to go the easy way – via the entrance below the Temple of the Oracle at Clair View Ruins (designed by designed by Snow Kelley). Step through the stained glass of the portal, and your voyage begins at the Cavern of Inner Wisdom; pay attention to local chat for a clue on how to proceed – but before you do move onwards, take the time to explore the halls built within the cavern. And when you are ready to travel onwards, don’t be fooled when confronted by an apparent blank face of rock after following the Cavern’s whispered instructions.

Beyond this first cavern lies an underground fortification, a place of hewn and shaped stone walls, where broad stairways of wood and stone connect different levels and long halls and shadowed arches hint at further destinations. Designed and built by Talus Ravenheart, it sits as a kind of hub with multiple opportunities of onwards exploration. But again, before stepping through any of the archways, take a moment to explore the passages also offered, because again there are places here to be discovered: catacombs with the memory of one passed, a broken wall leading to natural caves beyond which in turn lead to further secrets and spaces awaiting discovery.

Clair View Ruins and caves, The Realm of Rosehaven, September 2022

Such is the nature of this “hub” (for want of a better term), that describing what might come next is impossible, thanks to the multiplicity of options for onward travel available. And even if there were a proscribed route, providing a blow-by blow description of what might be found would spoil the experience of exploring the cave and caverns for yourself. Suffice it to say that as you select arches and routes and shaded tunnels, so might you find yourself in the abode of a practitioner of magic or the hideaway of pirates or tunnels adorned with crystals, leading the way to elven halls – or more besides; each one designed by one or more of the residents of Rosehaven, and thus given an individual flavour.

Along the way it is possible to come across interactive elements in various places and rooms as well – so should you find yourself in, say, a cellar where grapes are pressed into wine (to name but one) – be sure to mouse-over anything that looks like it might not actually fit with the rest of the room / cavern. Also, given that any route might lead you to an alley or dungeon or gateway or stairs leading to the world beyond the caves, the tunnels offer a unique means for discovering and exploring public spaces within the broader Realm; just remember that teleports into the network may not always be a portal or hidden in shadow; some might lie behind an innocent-looking door…

Whether used for exploration or for role-lay, the caves of Rosehaven add a further dimension to this engaging community, and are more than worth a visit.

Art and allegories in Second Life

The Vordun: Allegories of Artemisia, September 2022

Recently opened at The Vordun Museum and Gallery, operated and curated by Jake Vordun, is a stunning exhibition of art from the physical world offering a celebration and exploration of the life and work of Artemisia Gentileschi (1593-1656) also known as Artemisia Lomi), one of the most accomplished artists of the Baroque period, (c. 1625-1740).

Born in Rome on the 8th July, 1593, the eldest child Prudenzia di Ottaviano Montoni and noted Tuscan artist Orazio Gentileschi, Artemisia took up art at an early age, and was producing professional works by the age of fifteen. Like her father, she followed the innovations set by Caravaggio – such as the use of real models – whilst also developing a natural eye for the use of the brush and in the mixing of paint and use of colour to depict the female figure with a naturalism which extended beyond the more idealistic approach of her male peers.

Artemisia Gentileschi: Self-Portrait as the Allegory of Painting, 1638–39. Via: wikipedia

Initially regarded more out of curiosity than in recognition of her skills – she came to wider public knolwedge as a result of the trial of artist Agostino Tassi, who raped her when she was 18 – by the time she was in her early twenties, she had become the first woman accepted into the  Academy of the Arts of Drawing in Florence.  As her work gained a broader audience, so to did her career flourish through patronage and hard work, her art carrying her from Florence back to Rome, thence to Naples – and even to England and the court of King Charles I.

As well as its depth of realism, her work is notable for its focus on women from myths, allegories, and the Bible, with many featuring herself as one of – if not the – protagonists. Her art eschews the more accepted view of the female form – that of a gentle, sensitive, vulnerable creature – to instead present women as figures of power, strength, and the equal of men.

The exhibition at The Vordun – entitled Allegories of Artemisia – is an extensive look at Artemisia’s work offering one of the most unique gatherings of reproductions of her art to been seen outside of the printed page.  A collaborative display by Jake Vordun (producer), Marina Münter (vivresavie) – curator; Paul Gils (ObertonX) – research assistant; and Cibele Cibernética (profetadigital) – graphics designer, it is a multi-room exhibit made all the more abosrbing by its non-linear approach to Artemisia’s life and art, one which – in the words of those responsible for the exhibition:

[Traces] a parallel between the the characters she depicted in her paintings and her own life, the visitor gets the chance to experience real scale works by her and artists from the same period, given the chance to analyse visually the aspect of her work.

From the introduction of Allegories of Artemisia

The Vordun: Allegories of Artemisia, September 2022: Judith Beheading Holofernes (left: Caravaggio, c.1599; centre: Artemisia Gentileschi, c. 1614-20; right: Artemisia Gentileschi, c.  1612-13)

On accessing the exhibition from the gallery’s main hall, vistors should follow the route through the opening to the right. This takes a route through a series of rooms, starting with a general introduction to Artemisia Gentileschi, followed by a series of self-portraits that help into introduce both the artist and the artistic tradition of a painter focusing on a subject more than once during their career.

From here, further rooms offer reproductions of some of Artemisia’s more noted works drawn from biblical stories (including from deuterocanonical books of the Old Testament), together with reproductions of the same subject by her male contemporaries – thus providing that opportunity to directly compare the work of Artemisia with her contemporaries, and appreciate both the uniqueness of her depiction of female characters and the depth of naturalism found within her work.

Wall text in each room help contextualise the subjects of the paintings and also to provide historical / biographical information (such as on Artemisia herself or her father) where relevant. This set of rooms culminate in a three-part section dealing with the deuterocanonical character of Judith which include both Judith Beheading Holofernes and Judith and Her Maidservant. This in itself is an exquisitely framed and presented series of images – some of them the most famous of the Baroque period – forming an exhibition-within-an-exhibition.

The Vordun: Allegories of Artemisia, September 2022

Beyond these initial rooms lies a large hall that brings together further pairings and small groups of paintings by Artemisia and other artists of her period (one of which includes a piece by one of her few female contemporaries – Elizabetta Sirani), and well as individual pieces by Artemisia. This is bracketed to one side by two further “themed” sub-sections entitled Church Commissions and Mary Magdalene.

Throughout the exhibition there is a wealth of information carefully brought together by the organisers. Each painting is presented with a plaque supplying the title of the piece, the name of the artist, the approximate time in which it was painted, and where it resides today. In  typical Vordun style, these plaques can be clicked to display their information in local chat. Meanwhile, the main hall includes a timeline of Artemisia’s life, defined in terms of the recognised periods of her work as an artist, and the notable events within them, together with a small display of works by other artists and inspired by her work and life.

The Vordun: Allegories of Artemisia, September 2022

Since its inception, the Vordun has presented a series of long-duration, richly immersive exhibitions that seek to replicate the experience gained within a physical world museum, whilst presenting exhibits which either cannot be reproduced in the physical world or, if they do have something of a  physical world analogue, are far more accessible than their counterpart might be. All of this makes The Vordun an engaging visit, and Allegories of Artemisia adds to this enormously.

When visiting The Vordun, do be sure to accept the local experience and specifically for Allegories of Artemisia, make sure your viewer is set to Used Shared Environment.

2022 week #37: CCUG meeting summary – updated

Endless: Birdlings Flat, July 2022 – blog post

Update, September 19th, 2022: in response to the discussion concerning the upcoming mesh new starter avatars and encouraging creators to help develop an ecosystem of clothing and accessories for them (see In Brief, below), Alexa Linden forwarded the following comment to me:

Linden Lab plans to release devkits for our new Default Avatars after we’ve gone live with them. We’re waiting to make sure everything goes smoothly and no tweaks are needed. Once we’re happy with the results we’ll work on the documentation and devkits to make them available for ALL creators interested in supporting these avatars.

Alexa Linden, Septmber 19th, 2022

 

The following notes were taken from  my audio recording and chat log of the Content Creation User Group (CCUG) meeting held on Thursday, September 15th 2022 at 13:00 SLT. These meetings are chaired by Vir Linden, and their dates and times can be obtained from the SL Public Calendar.

This is a summary of the key topics discussed in the meeting and is not intended to be a full transcript.

Official Viewers Status

  • Release viewer: version 6.6.4.575022 – hotfix for Crash at ~LLModalDialog() – promoted September 15 – NEW.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself).
    • Maintenance P (Preferences, Position and Paste) RC viewer version 6.6.4.574750, issued September 6.
    • Maintenance 3 RC viewer, version 6.6.4.574727, September 1.
  • Project viewers:
    • Puppetry project viewer, version 6.6.3.574545,  issued on August 30.
    • Love Me Render (LMR) 6 graphics improvements project viewer 6.6.2.573263, July 21.
    • Performance Floater project viewer, version 6.5.4.571296, May 10.

Materials and PBR Work

Please also see previous CCUG meeting summaries for further background on this project.

  • Tangent spaces:
    • The glTF 2.0 standards are very specific about where tangent spaces are expected to be and behave. To this end, Second Life will use mikkTSpace tangents at least for PBR support.
    • There are internal discussions going on at the Lab as to whether this should be retroactively applied to existing meshes. If this is the case, meshes will have to be re-uploaded in order to have the correct tangents, do to the way bounding boxes are currently handled (the DA upload changes the coordinate frame of the original mesh, resulting in tangents being generated which do not match the normal map).
    • As it is, use of mikkTSpace tangents does increase Land Impact (LI), as the tangents are being stored inside the mesh alongside the normal information.  However, LL are currently running experiments to see if the tangents can be generated and stored without altering LI.
    • Until it is shown whether or not these experiments work, LL is requesting holding off on discussions about possible LI increases until they know what the likely scenarios is.
    • Alongside of mikkTSpace, this project will use per pixel binormal generation.
  • There is a mismatch between the colour space handling swatch in the viewer’s material’s editor and the glTF specification; the latter all calls for these colours to be in liner space, and in the viewer they are in SRGB space. This means that the values displayed by the swatch does not match the values which would be typed into a tool like substance Painter. It’s not currently clear how this mis-match will be handled.
  • Viewer:
    • Transparency and double-sided materials are now supported in the PBR development viewer.
    • To maintain commonality with the glTF specification, albedo in the PBR viewer is now called base colour.
    • Access to the PBR development server is via the Content Creation Discord channel, and requests to join that channel should be made in person at CCUG meetings. I am no longer able (at LL’s request) to furnish such information.
  • Again, this project is only focused on the materials elements of the glTF 2.0 specification, it does not including glTF mesh model import – although there is potential traction for this be a follow-on project, with the goal of eventually replacing COLLADA support for mesh uploads.
  • Ideally the Graphics team would like to structure work such that elements of the glTF 2.0 specification can be selected and then implemented within Second Life, thus presenting an “extensible” means of support the standard.

Puppetry Update

Please also refer to:

Notes:

  • Jiras from the Lab and users will now be available in the public Jira for ease of reference.
  • Meetings are held on Aditi (the beta grid) at the Castalet region Puppetry Theatre on alternate Thursdays at 13:00 SLT. The next meeting will be on Thursday, September 22nd, 2022.
  • Some users have been looking at using OpenXR  for Puppetry and enjoying some success.

In Brief

  • The New Linden Lab mesh New Starter avatar (see here for more): the project has reached the stage of the Lab (through the LDPW) generating a fixed set of content to support the avatar, which will be made available through the Library.
    • There is – as Patch Linden has indicated – the potential for content creators to be encouraged to support this new body and potentially provide a support ecosystem of clothing and accessories – although this will require a dev kit.
    • It’s been suggested that some existing clothing / accessory creators be invited to help test the new avatar.
    • Mention of the new mesh avatar triggered an extended discussion on the current state (and, for creators) pitfalls of the current multi-body / head marketplace and providing content, content efficiency, etc. As a more philosophical discussion (at this point in time) than a clear set of opportunities for improvements, the discussion largely falls outside of this summary.

Next Meeting

  • Thursday, September 15th, 2022.

Cica’s Pink Fairytale in Second Life

Cica Ghost: Pink Fairytale – September 2022

Every one loves a fairy tale, the opportunity to escape to a world where our imaginations can be exercised, to explore to lands far away, share in adventures and see good triumph. Fairy tales are stories we gain exposure to at an early age, and the four words that so often start them tend to remain with us forever – something English author Sir Philip Nicholas Outram Pullman once noted,  both in terms of the memories hearing the words can evoke and the escape they offer.

This power of fairy tales is the subject of Cica Ghost’s latest region-wide art installation which opened on September 12th. It takes as its foundation that quote from Pullman – an author who has perhaps enjoyed renewed exposure to a public courtesy of the BBC adapting his coming of age, multiverse-spanning trilogy His Dark Materials into a television series.

Cica Ghost: Pink Fairytale – September 2022
Once upon a time lasts forever.

– Sir Philip Pullman

Entitled Pink Fairytale, the setting offers an environment in keeping with its name: a pink landscape beneath a pink sky;  a place where pink flowers and trees climb towards the sky, and where the buildings and features of the setting resemble cakes and edibles topped with icing, and the cups of a carousel appear to be filled with ice-cream or some other delight, marking them as a haven for allowing the child inside to revel.

This is a place populated by animals and characters who in turn suggest stories and tales to the active imagination, where thrones with ears await a king and queen – or perhaps a princes and princess – the jug between them perhaps bringing forth thoughts of magic lamps. Elsewhere a princess can indeed be found, together with an entourage of geese – also often characters found within fairy tales –  and watched over by a elephant which, if not fairy tales, when certainly other famous childhood stories.

Cica Ghost: Pink Fairytale – September 2022

Scattered with little vignettes such as these and complete with Cica’s many places to sit or dance or – in the case of the bubble-burping fumaroles – float. Pink Fairytale is another light and fun installation form a Second Life artist who consistently offers us a reasons to smile. So, should you decide to hop over and experience Cica’s work first hand, do please consider making a donation to help her continue to keep us smiling.
