A Forgotten Hope in Second Life

Forgotten Hope, March 2023 – click any image for full size

I received an invitation from Clifton Howlett to attend the opening of his latest Homestead region build, and while I was unable to make the event on Saturday, March 18th, I did manage to hop over a couple of times over the weekend and take a look around. Working with Coralile Resident, Clifton is a region designer who puts together imaginative settings which offer places in which to retreat, relax, explore and have fun, each one a little different to the last.

With Forgotten Hope, Clifton and Coralile have come up with a most unusual setting. Hidden from much of the light of day yet still rich with natural growth, it takes a new turn in presenting both a place of mystery for those who like to create stories about the location they visit in-world, and a place where personal time and a little fun can be has for those just seeking to unwind.

A veil of darkness cloaks its mysterious depths, enticing explorers and spelunkers from far and wide to uncover the dark secrets it harbours. Amidst abandoned huts and a submerged ‘plane [you can] embark on an adventure like no other and immerse yourself in the eerie atmosphere of this enchanting location.

Forgotten Hope, March 2023

A journey through this underground location – quite where it might be is up to you to decide, but for reasons I’ll come to, I thought of it as perhaps a little twist on the Lost style of mystery – commences within a fairly nondescript cavern. Here, smoke from a slightly out-of-control wood fire pit is slowly – and doubtless suffocatingly – filling the space, encouraging people to seek escape through the arch of a tunnel to one side of the dome-like cavern.

Lit by a smaller fire held in check by a rock of stones, the tunnel floor is wreathed in creeping mist as it descends down roughly hewn steps and doglegs its way into a second chamber. This appears to have been long-used; chests of hand written scrolls sit against the round walls, together with barrels of who-knows what – dried food? water? both? – and stacks of candles and other signs of human occupancy. It is a place suggestive of age and darkness – if anything is to be gleaned from the scrolls at least.

Forgotten Hope, March 2023

An arch leads to a further small cavern where more oddments can be found – including, somewhat incongruously, an upright piano complete with stool and sheet music which all look in remarkably good condition. Both form a strange combination – the chests of scrolls contrasting with the piano and the heap of mouldering mattresses; however, the mystery of these caves is liable to fade into the background after passing through the wood door tucked to one side of this little dome of rock.

Beyond the door is a split in the rock, a narrow defile, a cave taller and somewhat brighter in natural light than those on the other side of the door, perhaps suggesting that daylight is not that far away – a feeling added to by the presence of vines on the walls. Someone has gone to great lengths to lay a path of carefully cut and placed logs to ease passage over the floor of this defile, complete with a hand-made ladder to help people over a rocky lip to reach the cave mouth beyond. This sits high up on a cliff face, the ground and surface of a body of water fed by water plummeting from further around the high cliffs and visible above the tops of trees. However, its is not open land, but rather a vast and high cavern.

Forgotten Hope, March 2023

Mist rises from the waters below the cave mouth to fold itself around the trees, and thin strands of cloud float around the cavern’s high roof, the sunlight which dapples the water falling through a jagged hole in the cavern’s dome, the stray clouds around the hole acting as a prism to break the light into finger-like beams of illumination pointing down into this netherworld of a place. In doing so they fall upon the element which gives this place a Lost-like feel: a partial carcass of an airliner broken and semi-submerged in the water and, perhaps the cause of the rend in the cavern’s roof.

Here is where more mystery grows: was it the people who survived the ‘plane crash who built the path lading back to the entry caverns – and the platforms with their ladders providing the way up to (or down from!) the high cave? Or were they merely the latest inhabitants of this strange world? The evidence of long-term habitation is intriguing: at “ground” level, there is a ramshackle cabin built into the remnants of a once massive tree; there are remnants of cut-stone walls suggesting ancient buildings; board walks and decks pass out over the shallow waters to connect with the the rest of this huge cavern space. Trees grow throughout, whilst a range of wildlife sitting beneath their boughs and amidst the wild grass.

Forgotten Hope, March 2023

If the cabin and other structures located here were built before the nose of the airliner arrived – then who built them? Who was responsible from shipping the large boiler system sitting within the corrugated sides of a ramshackle shed in the second large cavern? Is this a retreat from the world, or a place where people can end up apparently stranded by misfortune – or some form of strange experiment in the human condition? Maybe the weird hooded figure lurking within the setting has some of the answers; or perhaps you don’t find them important.

If you don’t, there’s more than enough to keep you occupied here – the large deck sitting over the water of the first of the big caverns is home to DJ events and dancing, whilst scattered throughout the caverns (and up in their rocky walls) are places to sit and cuddle or read a book, with sofa and wine available by the bottle whilst the local wolves, snakes and alligator are content to let people freely come and go without being in anyway bothersome.

Forgotten Hope, March 2023

A strange but engaging world, Forgotten Hope makes for an engaging visit and serves as a spark for the willing imagination.

The Biden Administration has published further details on it 2024 budget proposal in support of NASA in which further details of the agency’s “Moon to Mars Manifest were revealed. Key points on the latter include:

  • The crewed Artemis 2 mission, intended to fly a crew around the Moon in an extended mission similar to that of the successful Artemis 1, confirmed for November 2024.
  • Artemis 3, the first mission to return humans to the surface of the Moon by the United States, is scheduled for 2025.
  • Artemis 4, the second crewed landing on the Moon now pushed back to 2028, with annual landings from there on through to the end of 2031.
  • Both Artemis 3 and Artemis 4 will utilise the SpaceX Starship-based Human Landing System (HLS) for carrying crews to / from the lunar surface and lunar orbit, after which crew activities will switch to the (still to be contracted) “sustainable human landing system”.
  • 2024 will also – in theory – see a demo flight of the SpaceX HLS, whilst the end of 2025/start of 2026 will see work commence on the Lunar Gateway station with the launch of the power module and habitation module to their extended lunar orbit.
  • 2028-2031 will also see work continue on the Gateway station alongside of the lunar landings.
  • Automated mission to the Moon in 2027 will demonstrate lunar construction techniques for developing a base, extracting usable commodities from the lunar surface, and testing power systems. Further demonstrations of these will take place in 2030.

In support of the above will be a series of demonstrator missions in Earth orbit, as well as development work on Earth for longer-term goals. These include:

  • In-space propellant replenishment and storage for reusable lunar landers and deep space transportation vehicles under a programme referenced as CFM: Cryogenic Fluid Management, involving SpaceX (optimistically in 2023), Lockheed Martin (2025) and United Launch Alliance (2025).
  • Development and flight test of the NASA/DARPA DRACO nuclear thermal engine (see: Space Sunday: propulsion, planets and pictures), with the design to be completed by the end of 2024, together with a conceptual design for a nuclear electric engine.
  • Development and delivery of a nuclear fission power unit demonstrator for use on the Moon or Mars, to the surface of the Moon in 2030.

The budget proposal includes an immediate request for US $180 million for the agency to start seeking proposals for a “deorbit tug” for the International Space Station (ISS). This would be a vehicle developed over multiple years and at a total cost of around US $1 billion specifically designed to dock with the ISS in 2030 and the proceed to gently push it back into Earth’s atmosphere along s pre-planned course so that it burns-up and the large element splashdown at Point Nemo.

Also within the 2024 allocation is US $30 million in support of Europe’s ExoMars rover, and an increased request for NASA’s side of the proposed NASA / ESA Mars Sample Return Mission.

 ExoMars Back on Track /  Sample Return on Track for Budget Overrun

The US $30 million requested in NASA’s 2024 budget is in part to provide ESA with a launch service for Rosalind Franklin, ESA’s ExoMars rover vehicle, together with various technology support activities for a lander vehicle.

This project has had its share of issues over the past two decades, and up until 2022, the plan had been for a joint mission with Russia, the latter providing the launch vehicle and a lander to deliver the rover to the surface of Mars. However, Russia’s invasion of Ukraine ended all ESA / Roscosmos cooperation.

Since then, ESA has remained relatively close-lipped about the rover’s future, but in a recently update, mission personnel confirmed 2028 is now being targeted for the mission’s launch. In addition they indicated that the agency will now build a dedicated lander for the rover which will leverage NASA’s expertise in propulsion, power and heat shield development. In addition, ESA has resumed testing of Amalia, the rover’s test bed vehicle.

The video below provides an inside look at Rosalind Franklin, and what marked the ExoMars rover mission unique among Mars missions.

In the meantime, the ambitious NASA / ESA Mars Sample Return (MSR) mission is threatening to overwhelm other elements of NASA’s science programme.

For the 2024 budget proposal, the White House has requested US $949.3 million for MSR – 19% more than the budget projection. It also notes that expenditure on the project will increase over projections through to the planned launch in 2028.

Working in concert with NASA’s Perseverance rover, which has been collecting samples from its travels across Jezero Crater and has recently started caching them for collection by MSR, the sample mission is designed as a two-part mission using a ESA-developed Mars orbiter to return the Perseverance samples to Earth, after they have been collected from the surface by a lander / recovery / ascent vehicle, primarily built by NASA.

NASA has already delayed the Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy (VERITAS) mission, which had been due for launch in 2028 prior to being put on hold in November 2022 over concerns about MSR costs, and will now not launch before 2031 – if at all. Now, the Geospace Dynamics Constellation (GDC) mission, a 2013 heliophysics decadal survey recommendation, will now also be suspended. MSR itself was expected to exceed US $7 billion prior to it being revised in an attempted to lower costs – however, it was approved for continuance in 2022 under the  Planetary Science Decadal Survey, on the understanding total costs would not exceed US 5.2 billion – which it still might.
