15歲的Liv Perrotto是SpaceX與馬斯克的忠實粉絲，抗癌的日子裡，與馬斯克對話是她最大的心愿。遺憾的是，在離世前幾天，她雖接到馬斯克的來電，卻因身體虛弱未能接通，床頭的手寫問題清單也成了未解的遺憾。
這份清單里，藏著她對科技與二次元的熱愛：從「你會做自己的手機嗎」「特斯拉餐廳會擴張嗎」，到「最喜歡的動漫是什麼」「知道初音未來嗎」，甚至還問到了自己為Polaris Dawn任務設計的柴犬零重力指示器Asteroid，能否成為SpaceX的吉祥物。
Liv的母親將清單分享後，馬斯克很快在社交平台逐一回覆：不會做手機、特斯拉餐廳會擴張、新遊戲已在路上，最愛的動漫是《你的名字》，去過日本多次，最愛京都的teamLab，知道初音未來，也承認Ani的形象靈感來自《死亡筆記》的彌海砂。最動人的回應是最後一條——他答應將Asteroid定為SpaceX的官方吉祥物，讓女孩的創意永遠翱翔在星際之間。
No Yes Yes Your Name Yes, a several times. Kyoto. teamLab. Yes Yes Ok 😀
Liv的母親發文致謝：「謝謝你把我們最深的痛苦，變成了星空中永恆而美麗的存在。」
Elon, from the bottom of my broken heart, thank you. ❤️ You’ve kept my beautiful daughter Liv’s memory alive in the most extraordinary way, by making Asteroid, the official mascot for SpaceX. Liv poured her whole soul into designing that little dog in a spacesuit, dreaming of the stars just like you. Seeing her creation soar on Polaris Dawn already brought tears of joy. Knowing it will now be a part of every SpaceX mission, flying among the stars forever? That’s healing I can’t even put into words. You didn’t just honor a young girl’s dream, you are keeping her spirit alive. Liv’s love, her laughter, her unbreakable fight lives on through Asteroid, and every time a Falcon roars or Starship climbs toward orbit, a piece of my girl flies with it. I’m crying grateful tears right now. Thank you for this priceless gift. You’ve turned our deepest pain into something eternal and beautiful among the stars. @elonmusk
