My thoughts on the upcoming IFT-3 flight of Starship-Super Heavy

As of writing (12th of February), IFT-3 is currently scheduled to occur later this month, but it could still easily get delayed.

My prediction is that IFT-3 will probably achieve orbit and will probably conduct an internal propellant-transfer, but that the upper stage (SN28) will probably suffer a failure of some kind during reëntry, either being destroyed or deviating far from its targetted splashdown-zone.

It's safe to say that successful reëntry is unlikely on IFT-3. Here's why:

The Starship upper stage will be the largest reëntry-vehicle ever built.

This reëntry profile (a belly-first reëntry with four fins used for stability) is unique and has never been done before. Starship's belly-first orientation is inherently ærodynamically unstable, which is why it needs constant corrections from the four fins. It could get trapped in a nose-first or tail-first orientation, both of which might be more stable. Else, a loss of control would just result in endless tumbling.

We've already seen heatshield-tiles falling off during IFT-1 and IFT-2. In fact, more fell off the latter than the former due to higher ærodynamic pressures and engine vibrations.

A failure during reëntry would be consistent with the general pattern of testflight-failures established so far. Essentially, each flight is a failure, but less of a failure than the previous one.

Honestly, I don't know what could happen to the first stage booster (B10). SpaceX knows how to do boostback-burns and propulsive landings. It's seemingly just a matter of preventing the vehicle from blowing itself up. Engine reliability will probably determine the booster's success.

It'll be interesting to watch nonetheless.

The fate of the Artemis Programme now depends on the success of these test flights and in SpaceX rapidly developing and utilising this reüsable launch-system. Development has been ongoing for over five years now, and the vehicle has yet to reach orbit. The landing of astronauts on the Moon is scheduled for September 2026. How likely is it that SpaceX will have humans on the Moon in just two and a half years from now?

The importance of recognizing Palestine

• It corrects the historical record of previously negating its natural continuity

• It rectifies the false premise of a second-tier citizenry

• It welcomes Palestine in its rightful, senior place at the international table

• It respects its destiny and creates a safe space for its national future

• It promotes reconciliation

What if Paz somehow saved Sylwanin and the other kids from being, you know, killed. Just a little, wacky idea for you.

Ohhh, complicated question. I never imagined Paz was at Pandora at that time, tbh. Grace has been on Pandora for so fucking long, she's been there for 30 years. She's been there longer than Neytiri has been alive. There has never been a time Neytiri's life wasn't touched by the sky-people, which is sad to think about.

But back to Paz- I don't think she would've been around for that. BUT, if she was, well, it just postpones the inevitable, quite frankly. Sylwanin and Tsu'tey would've had their good relationships with Grace, and tensions would have continued for a while longer instead of the banning of avatars from Omaticaya land. I do think there would have been another incident that would've caused this ban, just later. Mining would have continued and Sylwanin is still alive and already disillusioned towards the humans. It just adds a really interested dynamic to Jake and Neytiri's relationship when Jake would enter the picture, Sylwanin would NOT be pleased; she was the biggest advocate for the humans beforehand, like Neytiri, I'm sure she feels somewhat responsible for the destruction.

Another note; I really hesitate at fanon characterization of Paz. It comes from a place of wanting Spider to have a parent he can think highly of, one who loved him and prioritized him and his ideals (and the comics hint this of course). In actuality, we know nothing about her except that she died in the Assault on the Tree of Souls. Aside from Trudy, every RDA soldier we see is extremely racist towards the Na'vi and is nothing but excited to wipe them out. I really caution against white savior-ing and humanizing the colonizers, it's a trait that is really overused in this series in particular. The recoms and Quaritch have no excuse and never will, and frankly, neither does Paz. It is really worrying how many people want to excuse them. I know you were just throwing out a scenario though.

me: feeling heavily vindicated by the reveal that the game is reliant on the concept of Nature in conflict of Free Will and Agency, the reclamation of the Self against a religious superstructure that relies on the erosion of the self and free will to feed a God-Tyrant’s consolidation of power (I am taking the sheep game very serious. Everyone is booing at me and telling me to lighten up. I’m sorry. It will happen again.)

I'solan Solar System - Planet Descriptions and System Diagrams, Visuals

Visual Description of First Landing

“Surrounded by black obsidian, lifeless, and a small river cuts through the rock on your right, leaving smooth edges on its banks. It’s the only sound. A ways off, you can see green plants of odd shapes and various sizes..(wind)(light).. It’s brighter than night should be and too dark for day; everything has an odd (stygian) blue cast to it. In the sky, a silver band is backlit by an endless number of stars.”

The I’sola live on one of a set of rotating twin planets (a binary planet system). These planets have opposite and interlocking magnetic poles, which allow them to stay as close as they are without incident - gravity pulling them together, magnetism repelling them, and inertia helping to keep them apart. Hoset and Ma’al, or Hephaestus and Pan, share both an atmosphere composed of oxygen and carbon dioxide (percentages varying throughout the year) and a glass ring made of shattered meteors that orbits the twin system. The planets themselves are vastly different from one another.

Hoset/Hephaestus

Hoset is the planet that is unable to support life. Throughout the year (623 days), carbon and other material falls to Hoset in the way of meteors. These materials build up until the system gets close enough to the sun on its elliptical orbit and Hoset lights on fire for a fairly short burning season (44 days), burning out all of the oxygen in the atmosphere and replenishing the carbon dioxide necessary for the I’sola that live on Ma’al. Hoset constantly faces the sun and rotates at about the same speed as Ma’al.

Ma’al/Pan

Ma’al is a black planet with large, fast-moving rivers running to the poles. As the ash from Hoset floats over and coalesces into these rivers and fertilizes much of the planet, it ends up at the poles where enormous geysers shoot it up into space, sometimes temporarily creating dark clouds in the sky. There are two times of Ma’al’s rotation cycle: the Ring and the Eclipse. The Ring lasts for three quarters of the rotation and  refers to what we would think of as nighttime, with a silver band of light standing out against the night sky, no moon to speak of. The Eclipse refers to Hoset standing out as a black circle in the sky, covering the sun but leaving a surrounding fiery afterimage, the ring fading into black as it draws away. During burning seasons, Hoset simply looks like a large sun. Each rotation lasts 31.5 Earth hours though the I’sola speak of time in terms of rotational degrees - 0°/360° being the center of the eclipse “Ban” (meaning halfway) and 180° being Midring. “Planetfall” is when many I’sola go to rest, looking like an inverted sunset/sunrise. 

Image 1 (Left): A diagram of the I’solan Solar System, with its binary planets: Hoset and Ma’al. The gray planet is Ma’al, consistently the furthest from the sun - the I’sola live here. Hoset is depicted as white, in its burning seasons, and black when it sits as a dreary, dead lump of rock. Hoset’s burning seasons occur when the planetary orbit is closest to the sun; it lights on fire and burns for two seasons throughout the year. The oval around the two planets depicts the glass ring that Hoset and Ma’al share. It is made of melted bits of meteors and it refracts sunlight around to the back of Ma’al even during its ‘night’.

Image 2 (Right): A diagram of the day cycle of Ma’al, as it relates to Hoset. Ma’al (in gray) rotates clockwise as depicted above. Between 45°-90°, Hoset is hazy and slightly more distant in the sky, the sun more blinding than eclipsed by the dead planet, and the ring slowly fades in or out with the darkness. At 0°/Ban, the center of the eclipse, there is a complete solar eclipse, a void backlit by the sun. During the burning seasons, Hoset looks fiery red.

Image 3 (Above): A depiction of the I’solan written calendar. The ring rotates vertically around the binary planet system, and the days can be tracked by the angle of it in the sky.

mildly frustrated with feeling like my Seawalker species is somehow not 'advanced enough' to count as a modern-level alien civilization because they do not have clothes or aboveground complex cities or tech (outside of medical use and emergency-only weaponry) but also like. how the fuck am i supposed to put clothes on a 9-foot-at-the-shoulder-sometimes-12 amphibious alien reptile with 8 limbs that lives in a climate that is on average 95 degrees fahrenheit at 100% humidity that spends an equal amount of time at sea and on land. and why the fuck would they need complex tools when two sets of those limbs are highly dexterous, they have tusks that are both specialized weapons and excellent tools for holding things when the hands are occupied or puncturing/carving objects, and they are the apex predators on land and near-apex predators in the sea. they dont fucking need clothes or complex tools outside of medical use they have everything required for comfortable living built in

I had a thought today that is either funny, disturbing or both, depending upon how you take it. So, the Mister and I went forth a-voting today and we went off to get ourselves some lunch. Coming home, we saw a homemade campaign sign on the side of the highway protesting / urging people to vote against a couple of candidates who were proposing an expansion of a local sewage plant. Me: Since I've had my brain in Trigun lately (I was writing a fanfiction chapter last night) I've been thinking about THOSE Plants - you know, the humanoid sapient caged-people ones who make and process everything on that planet. This means that SOME of them HAVE to be sewage-processors, doesn't it? THOSE POOR PLANTS! My Lovely Mister-Man: Meet Mario and Luigi. This one's Mario, this one's Luigi. Me: I think I'm going to write a fanfic about that now.

It's interesting seeing what other folks in my field are doing because it feels like it can definitely lean both into STEM or humanities, depending on the curriculum. I definitely got more of a practical, STEM-based education, but I know plenty of folks that got more focus on the conceptual and sociological aspect of it 🤔

About Lanthanum-57:

Located a little far from Copper-9, this exoplanet is very fortified due to the secretive nature of this particular Cabin Labs located here. Other than the higher-ranking members of JCJ, no one really knows the inner workings of the lab's top-secret areas, which make up a large portion of the grounds. Some Subject Drones tried to sneak in, only to turn into Sentinel food or explode on the spot.

To prevent anyone from trespassing, Lanthanum-57's Cabin Labs is guarded by a high-profile security system: aside Sentinels, there is a plethora of explosive laser beams, saws, etc.. Basically, the place is a typical death trap.

After CYN unleashed hell on Lanthanum-57, the outposts (which are also fortified, but not too much like the Cabin Labs) turned into refuges for Workers to retreat from the Disassembly Drones hunting them down. Moreover, the weapons stored in these outposts and littered in cities boosted the Workers' protection.

However, HIE has been proven as a challenge for them.
