Depends Who You Ask ![Virgin Galactic's suborbital spaceplane VSS Unity just reached an altitude of 82.7 km. But can we really call that space?]() *\Image: Virgin Galactic\* ## 50 Mile High Club Virgin Galactic just achieved a major milestone. But did it really make it all the way to outer space? That depends on who you ask. During today's powered test flight, Virgin's VSS Unity — the second SpaceShipTwo — reached an apogee of [51.4 miles]() (82.7 km). It burned its hybrid rocket engine for a full minute to get there, after it was released from the WhiteKnightTwo mothership at 50,000 feet. ## What's Space? Is that really space? It depends who you ask. NASA and Air Force astronauts officially become "astronauts" when they reach an altitude of 50 miles (80 km). But the most widely agreed upon definition is the so-called Karman line — 100 km or 62 miles, although those numbers might be [shifting slightly]() as well. After all, the SpaceShipTwo is a *sub*orbital spaceplane — a long shot from orbital flight, which is a whole lot further. To keep up free falling around the Earth in orbit, you'd have to get to above 100 km, which is roughly the Karman line. And the requirements of getting to either point are actually staggeringly different: orbital flight requires an energy budget that's 32 times that of suborbital flight, [according to the *Scientific American*](). ## A Big Achievement That's not to play down Virgin Galactic's achievement. It's perhaps the highest any horizontal take-off spaceplane ever flown, and Richard Branson's space tourism company should be applauded for that. Besides, Virgin Galactic is planning to fly even higher than that. The company's [2012 plans]() suggest the SpaceShipTwo spacecraft was supposed to reach a high point of 68 miles (110 km) — well above the Karman line. Futurism has reached out to clarify the venture's future plans for the VSS Unity. So is this all just pedantry? I'll leave that up to you. But if I were about to spend $250,000 on a Virgin Galactic ticket to space, I'd sure as hell want to go to "space." I'm holding on to my cash until I can buy a night at a space hotel. **READ MORE:** [Virgin Galactic just flew to 82.68 kilometers—is this space?]() \[Ars Technica\] ***More on the VSS Unity: [Virgin Galactic Is Going to Space. Depending on Your Definition of Space.]()*** ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
