This should say "space". It's very impressive still. Space is usually defined to be defined as starting at 100k altitude, when the atmosphere peters out, also called the Kármán Line. This only went to 60k. https://en.wikipedia.org/wiki/Kármán_line https://en.wikipedia.org/wiki/Kármán_line
Update: 82k. Sorry, the article I looked at first said 60k, that was wrong.
- citilife 8y agoThe first line in the article says: > The firm's SpaceShipTwo passenger rocket ship reached a height of 82.7km, beyond the altitude at which space is said to begin. Well above he 60km mentioned.
- Latteland 8y agosorry, you are correct, 60k was incorrectly listed in the article I looked at.
- philwelch 8y agoThe US definition of "the point where space begins" is 50 miles (80 km) above sea level, though this was mostly to eliminate an inconsistency between the NASA definition (which was the Karman line) and the USAF definition (which was 50 miles). Either way, it a fairly arbitrary point in a continuous gradient of decreasing atmospheric pressure that makes an even base-10 number in the predominant unit of measurement, so I guess you can pin this on Americans not using the metric system.

- airstrike 8y agokm, not k
- Groxx 8y agothey could've said "kj" and it still would've been clear from context.
- airstrike 8y agoIt would also still be incorrect...
- ceejayoz 8y agoMy Australian relatives say "it's about 50 kay" to describe driving distances, for what it's worth.
- crimsonalucard 8y ago50 kilomiles?
- richardknop 8y agoI read it as 82k meaning 82 thousand meters (k used often to mean thousand and altitude is often measured in meters).
