Question 1

宇宙に行くにはどれくらいの費用がかかりますか？

Accepted Answer

It depends entirely on the tier. A parabolic flight (no altitude gain, just weightlessness) runs roughly 6,700–8,850 with Zero-G. A stratospheric balloon flight to the edge of the atmosphere was priced at $125,000 with Space Perspective, though that company hasn't flown anyone yet. A suborbital rocket flight that actually crosses into space runs $750,000 with Virgin Galactic (currently paused) or a reported $150,000 to well over $1 million with Blue Origin (also paused). A multi-day orbital stay on the ISS with Axiom runs about $55 million per seat.

Question 2

実際に有料顧客を運航した宇宙観光企業はどれですか？

Accepted Answer

Zero-G (since 2004), Blue Origin's New Shepard (98 people across 38 flights), Virgin Galactic (six commercial flights, 2023–2024), Axiom Space (four ISS missions, 2022–2025), and Celestis for memorial spaceflights (24 missions since 1997). Space Perspective has not flown any crewed mission.

Question 3

亜軌道飛行と軌道飛行の違いは何ですか？

Accepted Answer

Suborbital flights cross into space briefly and come back down without completing an orbit of Earth — a few minutes of weightlessness, over in 10–15 minutes total, requiring roughly a day of training. Orbital flights actually circle the Earth, last days to weeks, involve months of astronaut-level training, and cost tens of millions of dollars rather than hundreds of thousands.

Question 4

実際、どのくらいの時間無重力状態を経験できるのですか？

Accepted Answer

On a parabolic flight, about 20–30 seconds per arc, roughly 5–8 minutes cumulative across a full flight. On a suborbital flight, a few continuous minutes above the Kármán line. Stratospheric balloon flights don't produce weightlessness at all — you're still under normal gravity the entire time, just at high altitude. Orbital missions mean continuous weightlessness for the full duration of the stay, whether that's 3 days or 18.

Question 5

宇宙観光は安全ですか？

Accepted Answer

Based on documented flight records: Virgin Galactic's fatal 2014 accident occurred during a developmental test flight, not a commercial passenger flight. Blue Origin's crewed flight record is clean across 38 New Shepard flights, though an uncrewed cargo flight suffered a booster failure in 2022 that the capsule's abort system handled without injury. Every operator requires medical screening before flight. With flight counts still in the dozens rather than the thousands or millions, there isn't enough data yet to make statistically meaningful safety comparisons between operators.

Question 6

故人の遺灰を宇宙へ送ることはできますか？

Accepted Answer

Yes, through Celestis, which has flown 24 memorial spaceflight missions since 1997, sending a symbolic portion of cremated remains or a DNA sample into space. Pricing ranges from $3,495 for a suborbital flight with remains returned afterward, up to $12,995 for a flight to lunar orbit or deep space. A Mars-orbit mission is in development, priced at $24,995, with no earlier than a 2030 target.
