方法を一つ一つ確認して、徐々に×印が増えていって、最後の手段も使えないことが分かってしまった後の絶望感を一身に受けてほしいな、と思いながら描いた絵です。

宇宙服単身で放り投げられるのではなくて宇宙船で漂流しているというのも、何とかできそう感が残っていてまた違った味がするなと思います。
(もしかして・・・？実は・・・？)とか思いながら、でも帰れない。

宇宙服単身と違って、なまじリミットまで十数時間とかあるからこそより諦めがつきにくいとか。

宇宙空間にはリカバリーできるものが何もないから、何か一つでも足りないと絶対に生き残れない・帰れないという宇宙開発特有のピリピリする感覚が好きです。

Art I drew while thinking, "I want her to fully take in the despair that comes after checking each method one by one, more and more Xs popping up, until realizing that her final recourse is unusable."

Rather than being thrown out in just a spacesuit, I think there's something different to being set adrift in a spaceship that comes from that lingering feeling of maybe being able to make something work.
Thinking, "(Perhaps...? Is it really...?)", yet being unable to return.

Like, as opposed to just a spacesuit, you have somewhere between 10 and 20 hours until you hit the limit, so it's that much harder to give up.

There's nothing you can use to save yourself in outer space, so if you're lacking just one thing, you won't be coming back alive; I love that tingly, nervous sensation unique to space exploration.
