About this expedition
What is it like to walk on the Moon?
This free, browser-based expedition puts you on the lunar surface in first person. You walk and jump in real lunar gravity — 1.62 m/s², about one-sixth of Earth’s — across a cratered plain under a black sky, with Earth hanging above the horizon. There is nothing to download and no account to create: it runs in any modern browser with WebGL, on a computer or a phone.
The Moon has almost no atmosphere, so sunlight is harsh, shadows are razor-sharp and the sky stays black even at noon. With no wind or rain, craters, boulders and footprints can survive for millions of years — the bootprints Apollo astronauts left between 1969 and 1972 are still there today.
Quick facts
- Surface gravity
- 1.62 m/s² — about 16.5% of Earth’s
- Distance from Earth
- About 384,400 km on average
- Length of a day
- About 29.5 Earth days, sunrise to sunrise
- Surface temperature
- About +117 °C (390 K) at the equator in sunlight to about −178 °C (95 K) at night (NASA Moon Fact Sheet equatorial diurnal range).
- Atmosphere
- Essentially none — a very thin exosphere
- Crewed landings
- Six Apollo missions, 12 astronauts (1969–1972)
Five discoveries to find
- A history of impacts — read a crater’s raised rim and sunken bowl.
- Written in stone — angular boulders and the fine regolith blanket beneath them.
- Everything we call home — why Earth barely moves in the lunar sky (tidal locking).
- Eagle has landed — a real NASA 3D model of an Apollo lunar module.
- Where sunlight never rests — a shadowed hollow, like the polar craters that may hold water ice.
How to explore
Press Step onto the Moon, then walk with W A S D or the arrow keys, hold Shift to move faster, press Space to jump and drag to look around. On phones and tablets a touch pad appears. Press G to compare the local gravity with Earth’s, P for photo mode, and E to record a discovery in your journal — progress is saved on your own device.
Science and artistic reconstruction
Lunar gravity, the black daytime sky, crater shapes and the lunar module model come from real science and NASA 3D Resources. The terrain, rock placement and observation points are procedurally generated art, not a map of a real landing site, and Earth’s position in the sky is composed for the view.

关于本次探索
在月球上行走是什么感觉？
这是一场免费、可直接在浏览器中进行的第一人称月面探索。你将在真实的月球重力下行走和跳跃——约 1.62 m/s²，只有地球的六分之一左右——穿过漆黑天空下布满陨击坑的平原，地球悬挂在地平线上方。无需下载，也无需注册账号：任何支持 WebGL 的现代浏览器，电脑或手机都能直接运行。
月球几乎没有大气，阳光刺眼，阴影边缘锋利，即使正午天空也是漆黑的。没有风雨侵蚀，陨击坑、岩石和脚印可以保存数百万年——阿波罗宇航员 1969 至 1972 年留下的靴印至今仍在那里。
快速数据
- 表面重力
- 1.62 m/s²，约为地球的 16.5%
- 与地球的距离
- 平均约 38.44 万公里
- 一天的长度
- 约 29.5 个地球日（从日出到日出）
- 表面温度
- 赤道阳光下约 +117 °C（390 K），夜间约 −178 °C（95 K）（NASA 月球概况表的赤道昼夜温度范围）。
- 大气
- 几乎没有，只有极稀薄的外逸层
- 载人登月
- 阿波罗计划六次，12 名宇航员（1969–1972）
五个发现
- 撞击留下的岁月 — 读懂陨击坑隆起的边缘与下陷的坑底。
- 石头里的故事 — 棱角分明的岩石，以及覆盖其下的细碎月壤。
- 我们称之为家园 — 为什么地球几乎不在月空中移动（潮汐锁定）。
- 鹰已着陆 — 阿波罗登月舱的真实 NASA 三维模型。
- 阳光照不到的地方 — 阴影凹坑，类似可能藏有水冰的极区陨击坑。
如何探索
点击“踏上月球”，然后用 W A S D 或方向键行走，按住 Shift 加速，按空格键跳跃，拖动鼠标环顾四周。手机和平板上会出现虚拟方向键。按 G 对比当地重力与地球重力，按 P 进入拍照模式，按 E 把发现记录进探索手记——进度保存在你自己的设备上。
科学与艺术重建
月球重力、白天漆黑的天空、陨击坑形态，以及登月舱模型都来自真实的科学资料和 NASA 三维模型库。地形、岩石位置和观察点由程序生成，属于艺术创作，并不是某个真实登陆点的地图；天空中地球的位置也是为画面构图而设定的。
