Lyrics・歌詞 (JP):
宇宙飛行士さん、久しぶり
色んなこと思い出してる
伝えそびれたことも
昔声かけてくれた人

数え切れない君の傷
雑草に茂った君の芝生
君が逝ったからどんな惑星
見つけたたの？教えてよ

君の姿はロケットのよう
ずっと追いつけない場所に飛んで行く
もう会えないことわかってるけど
最後の日まで演技は続く

宇宙飛行士さん、久しぶり
ちゃんと前に進んでいるよ
知らないことが溢れる
君のことどんどん忘れてく

憧れと嫌いに揺れる
くだらなくても辞めない任務
あの空に見てたのは
本当だったの？教えてよ

君がいたロケットは高く
手が届かない場所に飛んで行く
鏡に見れば後悔なんてないけど
どうしてもみっともない涙が落ちる

君の声が呼び掛けている
誰も知らない言語で返す
ずっと叫んだ
叫んだ
叫んだ
叫んだ
叫んだ
叫んだ

宇宙飛行士さん、久しぶり
来年のことはわからない
一歩ずつに歩き出す
いつか泡のように消えて行く

Lyrics・歌詞 (EN):
Long time no see, Mr. Astronaut.
A lot of memories come to mind.
The things that I didn't get to say.
The people calling out to me ages ago.

I saw the wounds on you that I could never count.
I saw the weeds slowly spread all over your lawn.
Since when you left all that time ago, what kinds of planets,
Did you get to see? Would you tell me?

Your figure was just like a rocket to me.
Flying far away to where, I can't catch up anymore.
I know I probably won't get to see you anymore.
But until that last day, the act goes on.

Long time no see, Mr. Astronaut.
I'm moving forward like I'm supposed to do.
The things I don't know, grow and overflow.
The things about you I forget more and more.

Wavering between longing and dislike.
A pointless task I can't seem to do away with.
What you saw in that sky that day,
Was it even real? Would you tell me?

That rocket of yours kept flying up high.
So far away to a place my hands can't reach.
Looking into the mirror, I find no regrets at all.
Even then I see those shameful tears start to fall

I could hear your voice calling out to me.
In a language no one knows, I was always answering.
Always shouted out
Shouted out
Shouted out
Shouted out
Shouted out
Shouted out

Long time no see, Mr. Astronaut.
I don't know what might come about next year.
Just walking forward, one step at a time.
And disappear like foam one day.
