AWS CEO Matt Garman：太空数据中心至少还需 10 到 20 年
AWS 的掌门人直接给太空数据中心泼了盆冷水：全球连一天一发的火箭都没有，一机架 GPU 就有一吨重，太空中散热和维修更是硬伤。他把账算得很细，做算力基础设施判断、评估这类创业项目时很值得对照着看。
AWS CEO Matt Garman 在 Sources Podcast 访谈中表示，太空数据中心在经济上可行至少要等 10 到 20 年，未来一二十年内难以落地。他给出的核心数据是：AWS 目前每 14 秒就向地面数据中心部署一块 GPU，而全球发射频率连一天一次都不到，一机架 GPU 重量可能达到一吨，运力缺口极大。
他逐一拆解了几个常被忽视的工程难题：太阳能板通常只产生千瓦级电力，而业界谈论的是吉瓦级数据中心；太空虽冷但没有空气，散热实际上非常困难；还有普遍存在的辐射问题，服务器制造成本更高且几乎无法现场维护。
Garman 承认这些问题在技术上都可以解决，但强调没有任何单一路径能快速改变现状。这一表态与近期多家公司热炒的太空算力概念形成对照，对评估相关创业项目的落地时间线有参考价值。
AWS CEO Matt Garman: Data centers in space are at least 10 to 20 years away.
"I think that it is highly unlikely to be economically feasible or practical in the next decade or two.
It sounds good. You get free energy and it’s up there somewhere. Launches are still relatively infrequent and expensive. One person is not going to fix it. We as a world don’t do one launch a day today.
We’re landing in a data center today one GPU every 14 seconds. So we don’t do a launch a day for the world, and that’s just us doing one GPU.
A rack of GPUs might weigh a ton. I don’t even know if you can stick that on a launch vehicle or how many you can get up there.
People talk about gigawatt data centers and megawatts of racks. Most solar panels drive kilowatts, not gigawatts. So you need these gigantic things that are up there.
They’re really hot. Everyone’s like, space is cold. Space also doesn’t have air. Dissipating heat in space is actually quite hard.
It’s just a really hard environment. There’s radiation everywhere. It’s going to be way more expensive to build servers, from a serviceability point of view.
These are all technically solvable problems, and it’s just going to take a while. I’m not saying any one of these things is impossible. I just think that it’s way far out."
