Map Of The Solar System From Signalis

STS-31 on Approach by NASA on The Commons

I came up for the idea for this one while looking out of my airplane window. In the last two years, I’ve travelled a lot, and I have a love/hate relationship with it. I don’t like the feeling of being away from home, and feeling slightly lost. But I love the feeling of having nothing to do but letting my mind wander, and thinking about places I’ve never been before. This piece is inspired by that mellow feeling ~

I feel like the world could benefit from a realistic visual sci-fi that heavily focuses on characters and moods. Space as it really is has a huge potential for moods. The way in which space exposes humans to all number of dangers, physical and psychological, is something that has not really been explored enough.

I doubt that every space habitat will have spin gee. If we understand our current political system, we can assume that a freefall, non-rotating habitat would be cheaper to live in. People who decide to move to space for whatever reason will use their life savings to find a cramped, tiny cupboard in some space station.

Your bones get thinner. Your eyesight gets worse. Your blood pressure goes down. You don't feel as hungry. Your muscles shrink. Your skin loses all its tan from hiding in the dark. The tops of your feet get calicoes from hooking onto things.

You get depressed. Isolated. Claustrophobic. Tired of seeing the same room every day. Irritable. Irrational. Anxious. After a long time, atheists would turn superstitious.

These things have been explored a bit from what I've seen, but they seem to be background elements of some greater story. Maybe it's just not possible to make this topic the focus of a movie. The closest I've seen is Ad Astra, which is an okay movie.

We will eventually spend years in space. Someday, people will be born there. We will be sickly and depressed, even with spin gee. This would have signified the ultimate migration of human living from the natural to the mechanical. From death by biology to death by astrodynamics. Where you have to be a technical genius to not die if something malfunctions.

Space is not luxurious. People won't actively choose to move there en masse without a good reason. Migration into space will take hundreds of years.

Don't get me wrong, The Expanse is one of my favourite shows, but I don't watch it for the combat and politics.

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?

A solar cycle: a montage of 10 years worth of x-ray images taken by the ようこう (Yōkō 'sunbeam') sun-observation satellite.

The Sun undergoes a cycle of magnetic activity with a period of about 11 years. At solar maximum, solar observatories see more sunspots on the Sun's surface. Solar flares and coronal mass ejections are bigger and more frequent, triggering auroræ in Earth's skies, interfering with some types of radio communication, and irradiating deep space hardware. The Sun's magnetic field also undergoes a polarity inversion during solar maximum, when the north and south magnetic poles on the Sun swap (this happens again 11 years later in the next maximum). By contrast, the solar minimum has very few or no sunspots and the Sun is generally calm; a good time for deep space missions.

The last solar maximum was in February 2014. The last minimum was December 2019, marking the transition from cycle 24 to 25 (records began in 1755). The next maximum is predicted for the second half of 2025.
