Space Sunday: balloons, rockets, rovers, returns

Almost a year ago, I wrote about a company called Space Perspective and their plan to offer fare-paying passengers the chance to experience high-altitude balloon flights which, while failing to cross (or even come close to) the Kármán, will give the unique experience in rising to altitudes sufficient enough to witness the curvature of the Earth and see first-hand the tenuous nature of our protective atmosphere. And to do so in unique comfort.

As I reported in Space Sunday: balloons to space, Mars movies and alien water clouds, Space Perspective intend to offer passengers a six hour trip into the upper atmosphere aboard a luxury capsule slung beneath a gigantic helium balloon. And the price? US $125,000 per person – which sounds a lot, but is actually half that charged by Virgin Galactic for a flight lasting around 65 minutes, and who knows how much cheaper than a 12-minture trip aboard a Blue Origin New Shepherd vehicle.

Obviously, both Virgin Galactic and Blue Origin have the added attractions of allowing passengers to experience microgravity for about three minutes and then collecting their (unofficial) astronaut wings on their return – neither of which are part of Space Perspective flights; which “only” rise to around 30-32 km. However, the watchword for Space Perspective trips is going to be a level of comfort well beyond anything Virgin Galactic or Blue Origin can achieve.

Just how much comfort has now been revealed by Space Perspective as they start to move ahead with the design of their full-scale Neptune capsule. In particular, the company has released a 3D interactive model of the capsule’s interior, demonstrating the 4 pairs of passenger seats located on other side of the capsule, the central bar / snack area alongside the access door.

In addition, the capsule has mood lighting and includes something necessary for a 6-hour flight: a lavatory (complete with its own window of its own so those needing it can continue to enjoy the view!). The passenger seats are designed to conform to the sitter’s body to offer maximum comfort and are fitted with fold-away tray tables. Potted plants add to the overall ambience while the floors and walls of the capsule covered in fabric to absorb sound and add to the sense of privacy.

Finally, the bar can be loaded with snacks and beverages in according with passenger’s preferences, whilst a central information display and wall-mounted tablets provide information on a flight. In addition the cabin will be equipped with wi-fi connectivity back to Earth, and heads-up displays may be included in the windows to help point out locations of interest visible beneath the clouds some 20 kilometres below the capsule as it cruises at altitude.

Flights will comprise a land-based launch From the Florida Space Coast with a 90-minute ascent to cruising altitude. The capsule will remain at its cruising altitude for around two hours before starting an equally gentle descent with a splashdown on water where the will be met by a support ship / yacht that will offer comfortable facilities to the passengers while the capsule is recovered, and then return them to land.

Should problems occur with the balloon during any phase of a trip, ground controllers can command the capsule to detach and drop aerodynamically to an altitude where parachutes can be deployed to slow the descent and cushion splashdown.

Space Perspective has recently secured a further US $40 million in funding to allow development of the full-scale Neptune capsule to proceed, and has secured the first of three hoped-for patents relating to the capsule’s unique structural design. In addition, the company states it already has 600 people who have paid for seats on flights, which are due to commence in 2024.

SLS: WDR Halted, Rocket to Return to VAB

In what is fast becoming something of a humiliating train of events in trying to get its first Space Launch System (SLS) rocket ready for launch, NASA has abandoned the critical wet dress rehearsal (WDR) and will be returning the rocket to the Vehicle Assembly Building (VAB) for a series of updates.

As I’ve reported over the last few week, the WDR is a last, critical step in ensuring the rocket and all its support systems – the mobile lunch platform, the propellant loading system, the launch control systems, etc., are ready to make a launch attempt. After been rolled out to launchpad 39B at Kennedy Space Centre, the WDR started on April 1st, and should have lasted three days.

However, that initial attempt had to be twice scrubbed as a result of issues within the supply of nitrogen gas (used to help purge and cool part of the launch system) to the vehicle. Correcting these issues took several days, prompting a further delay in resuming the test to make way for the launch of the Axiom Ax-1 private crew to the space station from the SpaceX facilities at neighbouring Pad 39A (see: AX-1 Artemis, ESA & a galaxy far, far away).

The intention had been to resume WDR processing on April 9th, but on April 7th, a fault was detected in pressure valve in the rocket’s upper Interim Cryogenic Propulsion Stage (ICPS). Rather than delay the test for at least a couple of months by returning the rocket back to the VAB to fix the faulty valve, NASA determined a process by which the test could continue with only “minimal loading” of the tanks on the ICPS, and pushed the resumption of the test back until at least April 12th to allow the necessary procedures to be properly revised.

Operations in fact resumed on April 14th – and almost immediately came to a halt due to propellent loading issues with the liquid oxygen. No sooner was this triaged and fixed than an over-pressure situation was detected within the liquid hydrogen tank, again bringing operations to a halt. After reviewing the situation again, NASA tried once more to resume propellant loading in a “modified” state, only for a hydrogen to be detected leaking from an umbilical line connecting the core stage to the mobile launch tower, again bringing operations to a halt.

The cause of the leak was found to be with the same nitrogen feed / purge system that caused the original problems at the start of the WDR process on April 1st. As a result, NASA announced late on April 16th that all WDR activities are now curtailed, and the rocket will be rolled back to the VAB to allow the problems with the nitrogen umbilical system to be addressed, and the valve in the ICPS to be fixed or replaced. The roll back will also be used to further investigate the liquid hydrogen over pressure issue on the core stage tank.

No date has been given on when the roll-back will occur  – there will be a further meeting to discuss this on April 18th. However, the move does mean that any Artemis 1 launch is unlikely to come before July at the earliest. However, to present further delays once the vehicle has been returned to the pad, mission managers are said to be considering – assuming the WDR runs flawlessly – moving directly from the test to launch readiness preparations without again returning the vehicle to the VAB for post-WDR inspections.

The Tempura Project in Second Life

Tempura Project, April 2022 – click any image for full size

April saw some excitement / concern over the future of one of the longest-running public spaces in Second Life, when news surfaced that Japanese Tempura Island looked set to close its doors. Calls were made for Something To Be Done – and fortunately, the Lab was able to step in and add the region to its growing list of spaces preserved under its Second Life Region Preservation Society (SLRPS) banner.

I confess that while I’ve visited Japanese Tempura Island on numerous occasions in the past, I’ve never actually blogged about it. The main reason for this is because during those visits (back in around 2010-2013), the system I had just couldn’t handle the load, and while my present system has the “umph”, I have to admit that it fell off of my “destination radar”. However, while the recent news has brought the region sharply back into focus, I’m actually not going to blog about it now; I’ll reserve that for a future article.

Tempura Project, April 2022

Instead I’m going to focus on another Tempura region – the Tempura Project. Initiated at the time when Japanese Tempura Island’s future was in doubt, the aim of the project was initially to offer a setting that emulated the original’s look and feel (whilst using mesh to replace some of the original’s older prim elements) and preserve all that made the original so popular among Second Life residents.

The project has been led by Tribish Tammas, whom I first got to know through The Muse region (see: Finding The Muse in Second Life and A new Muse in Second Life for more), and while the original is now being preserved, by the time this was confirmed by Linden Lab, more than 70% of the region had been completed.  As a result, the team decided to push ahead and complete the first stage of their work.

From day one it was never meant to be a duplicate of tempura but take the elements that made it such a peaceful place to relax. So people will have the classic version and something a bit more up to date to choose from 🙂 . Our focus is on places to relax with people you care with. Also great for taking photos. Certain elements are fixed in place – the bridge, tai chi , meditation, and the ball room; others will evolve over time. Hence the project name.

Given the original goals of the project as stated above, and the fact so much of the work had been completed prior to the original coming under the protection of Linden Lab, it should come as no surprise that Tempura Project does reflect the original in general look and feel. However, this does not mean the Project should be in any way dismissed. If there is one thing that has been noticeable with SLRPS is the fact that, as good as the project is in preserving regions, it actually does little to retain their original broader functions and the activities that were once organised within them (an example of this can be see with the SS Galaxy, once a healthy venue for events from weddings to mini-golf to skydiving and clay pigeon shooting contests and so on).

Tempura Project, April 2022

As such, Tempura Project is designed to be a living space, evolving in reflection of the uses to which it is put by visitors and the suggestions they pass on for possible additions and activities that are in keeping with the overall aims for the setting.

Those familiar with the original will recognise the inspiration for the landing point, bridge and dance hall, together with the two small islands bracketing the bridge. The latter continue to offer tai chi to one side, while the other round island sits as a Zen garden set out for yoga. The great hall might not be as big and impressive as the original, but it holds its own secrets beneath its dance floor that offer opportunities for swimming, message, the luxury of a steam room and more.

Tempura Project, April 2022

This is not the only underground element to the setting – but finding the other will take a little ingenuity. All I’ll say is: look for the wall with the Tempura mural. Elsewhere, much of the landscape retains the look of the original but is also smoother and a lot “cleaner” in form; much of the glow that permeates the original is absent from Tempura Project, and I feel that this is to the better. The landscape also offers more in the way of seating and cuddle spots waiting to be found by explorers. Elsewhere – and also awaiting discovery by the keen-eyed – is an underwater walk, whilst the wizard’s house offers both an excellent view over the lake to the grand bridge and forms a further cosy retreat.

With enough of its own touches combined with those aspects reflecting Japanese Tempura Island, the Tempura Project offers an engaging alternative to the original, the features unique to it clearly adding to its appeal. Given the popularity of the original, and the fact it has always tended to remain constant, rather than gently evolving, Tempura Project may well offer those looking for a quieter sense of relaxation with the tonic they are seeking.
