On Monday, April 23rd, 2018, Linden Lab issued an invitation to live music performers to apply to be a part of the Second Life 15th Birthday celebration’s Music Festival.
2018 marks the fourth such festival the Lab has organised. It will be held as a part of the official Second Life Birthday celebration, taking place in mid-June 2018. For the successful applicant, it will be a paid event.
Since we started Music Fest in Second Life, we’ve held an audition showcase to highlight some of the musical talent in the Second Life community. Many of you have been performing for years in virtual venues all over the grid, and we’d love to have you come showcase your talent at the try-outs for this summer Music Fest. All genres are welcome! From bands to solo acts, rock and roll to electronica – we encourage anyone to sign up for consideration. The Second Life Music Fest is an opportunity to perform at one of the biggest celebrations in Second Life, and it’s a paid gig!
While we encourage everyone to sign up, it is not a commitment on your part and does not guarantee a spot at the auditions. We will review all submissions and extend audition invitations via email to the designated contact. Each invited act will have a short audition time (5 minutes max) to play and leave an impression on a panel of judges made up of Lindens and Residents. This panel will select acts to be invited to perform at the Second Life Music Fest. Upon completion of a half hour slot at the festival, the designated contact for each act will be eligible for payment (subject to Linden’s terms and conditions).
Those interested in taking part are invited to complete the audition application form – and to do so no later than Friday, May 18th. The blog post notes that completion of the application does not signify a commitment on the part of the artist to take part, nor a guarantee they’ll be called upon to audition before a panel of judges comprising Lab personnel and residents.
Musicians who are selected to audition will receive word directly from the Lab via e-mail. Those successful in their 5-minute audition, as judged by a panel of Lab staff and residents, will be invited to perform a 30-minute set at the Second Life Music Fest, and (subject to the Lab’s terms and conditions) receive payment for doing so.
The auditions will take place on (times are SLT):
12:00 noon to 14:00 Friday, June 1, 2018.
18:00 – 20:00 Saturday. June 2, 2018.
The venue for the auditions will be announced in due course and all residents are invited by the Lab to attend the auditions as a part of the audience.

Current Release version 18.104.22.1683644, dated March 27th, promoted April 13th – formerly the Media Update RC.
After a two-day delay, NASA’s Transiting Exoplanet Survey Satellite (TESS) launched from Cape Canaveral Air Force Station atop a SpaceX Falcon 9 booster on Wednesday, April 18th.
As I previewed in my previous Space Sunday report, TESS is designed to seek out exoplanets using the transit method of observation – looking for dips in the brightness of stars which might indicate the passage of an orbiting planet between the star and the telescope. Once in its assigned orbit and operational, TESS will work alongside the Kepler space observatory – now sadly nearing the end of its operational life, and eventually the James Webb Space Telescope – in seeking worlds beyond our own solar system.
It will be another 56 days before TESS has reached its unique orbit, a “2:1 lunar resonant orbit“, which will allow the craft to remain balanced within the gravitational effects of the Moon and Earth, thus providing a stable orbital regime which should last for decades. However, the launch was perfect after issues with the Falcon 9’s navigation systems prompted the initial launch attempt on Monday, April 16th. Once it had lifted the upper stage and its tiny payload – TESS is just 365 kg in mass and about the size of an upright fridge / freezer combination – the Falcon 9’s first stage completed a successful burn back manoeuvre and made a successful at-sea landing on the SpaceX Autonomous Drone Ship Of Course I Still Love You, waiting some 300 kilometres off the Florida coast.
The second stage of the rocket placed TESS into an initial 250 km circular orbit about the Earth before shutting its motor down for a 35-minute cruise period which correctly positioned the vehicle to allow the engine to be re-lit and send TESS on its way towards a 273,000 km apogee orbit. Over the next several weeks, the instruments aboard TESS will be powered-up and calibrated, including the four cameras it will use to imaged the stars around us in an attempt to locate planets orbiting them.
The first exoplanet – the ” hot Jupiter” 51 Pegasi B, unofficially dubbed Bellerophon, later named Dimidium and some 50 light years away – was discovered in 1995. In the 23 years since that event, some 3,708 confirmed planets (at the time of writing) have been found, with a list of several thousand more awaiting verification. Most of these have been discovered by using the transit method, with the vast majority by the Kepler space observatory. Such are the capabilities of TESS, it could double this count during its whole-sky survey, the first phase of which will last two years.
TESS’s primary mission is scheduled to last two years – but it orbit means it could study the skies around us for decades, seeking out planets amount the 200,000 stars that are the nearest to us.
SpaceX: Party Balloons and Bouncy Castles?
Elon Musk loves to tease. He’s also generally in earnest when discussion space flight. Sometimes the two things combine in unusual ways. Take a trio of tweets he sent on April 16th, 2018, for example:
Precisely what he meant has been the subject of much Twitter debate and theorising in various space-related blogs, but the CEO of SpaceX is now keeping mum on the subject; most likely enjoying the feedback and making plans.
SpaceX has serious ambitions to make their launch vehicles pretty much fully reusable. As we already know, the company has pretty much perfected the successful landing, refurbishment and re-use of Falcon 9 first stages (also used in triplicate on their Falcon Heavy booster), and plan to use the same approach with their upcoming BFR – standing for Big Falcon (or at least, a word that sounds close to “Falcon” but with a cruder meaning) Rocket – formerly, the Interplanetary Transport System.
To date, SpaceX has successfully recovered 24 Falcon 9 first stages, with almost half of those recovered now refurbished and either re-flown, or awaiting re-use. But the first stage – which does all the heavy lifting, is perhaps the “easiest” element of the vehicle to recover. It does not achieve orbital velocity (around 7,820 metres per second, or 17,500 mph), but instead tends to reach a peak velocity of around 1,716 metres per second (roughly 3,800 mph or Mach 5).
While this is still enough to generate a significant amount of heat and cause a first stage to break-up / burn-up in an uncontrolled descent, it is “slow” enough to avoid the need for extensive (and heavy) shielding to protect against the friction heat of passage back into the denser part of Earth’s atmosphere, providing the stage can be oriented correctly so three out of its set of nine motors can be re-lit. The exhaust plume from these forces the atmospheric compression generated by the rocket’s penetration of the upper layers of the denser part of the atmosphere (and which actually generates the associated re-entry heat), to occur away from the rocket, so the need for additional heat shielding is avoided.
However. recovering the upper stage of the rocket is altogether a different proposition. This does reach orbital velocity, and so finding a way in which it can be safely recovered without relying on expensive and heavy heat shielding which would both increase launch costs and reduce the payload carrying capabilities of both the Falcon 9 and the Falcon Heavy is a doozy of a problem. So much so, that SpaceX have twice cancelled attempts to make the rocket’s upper stage recoverable – and as recently as late 2017, it was believed further attempts at trying to get the stage to a point where it could be recoverable had been abandoned in favour of focusing on the BFR’s massive upper space ship stage – which as a crew / passenger carrying vehicle needs to be able to make safe landings.
So what do Musk’s tweets mean? how could a balloon be used to slow a vehicle and help it through the searing heat of orbital re-entry (where the heat load is around 27 times hotter than the heat experienced by the first stage)? The most likely explanation is that SpaceX are exploring the potential of using a ballute – a portmanteau of balloon and parachute – with the upper stage.
It’s time to highlight another week of storytelling in Voice by the staff and volunteers at the Seanchai Library. This week, all tales come from the Halls of Story, Fantasy Faire, 2018, unless otherwise indicated.

Join Caledonia Skytower at the Golden Horseshoe in Magicland Park, as she reads from Betty MacDonald tales of Mrs. Piggle-Wiggle.
Monday, April 23rd 19:00: The Crucible of Time
Gyro Muggins reads the fix-up by John Brunner. First published as two-part story which appeared in Isaac Asimov’s Science Fiction Magazine, it’s an ambitious tale of alien intelligence which grew to a series of six linked tales pushed as a single novel in 1983.
Far off in space is an alien race which is so much like us, yet so un-alike. From the birth of their earliest civilisation through to their attainment of star flight as their star system passes through the galaxy, we follow their development through the ages.
Aquatic by nature, this race presents some significant challenges well outside the realms of anything encountered by humanity. But they are also driven by all too familiar hopes, fears, desires, needs, wants, prejudices, impact of religious ideologies, and the quest for knowledge we have experienced in the growth of our own civilisation.
Charting six periods of time, each a thousand years after the previous, the six stories focus on the efforts of a group of individuals in each era as they face one or more challenges, their success in overcoming these challenges inevitably leading them towards a greater understanding of their planet’s plight, and ultimately, the ability to deal with that plight and the survival of their civilisation.
Tuesday, April 24th 19:00: National Lampoon’s Doon
In a distant galaxy, far, far away, a plot is brewing as vast and elaborate as the Empire itself…
Evil powers plot to harvest the wild pools of beer that grow only on the savage, sugar-swept world of Doon, take control of the native pretzel population, and turn the plucky little orb into the lounge-planet of the universe!
And only one man, Pall Agamemnides, heir to a dukedom can stop the galaxy-wide web of conspiracy and intrigue that is being fomented, and bring an end to the threat facing Soon.
Although reliant on a knowledge of both Frank Herbert’s sprawling story of Dune and Herbert’s often heady and flowery prose, Ellis Weiner’s tongue-in-cheek Doon is a masterpiece, offering a perfect parody of Herbert’s novel and brilliantly and accurately mimicking his prose.
Join Corwyn Allen as he resumes his reading.
