虽然有几家航天局已经宣布计划在月球上建造半永久性建筑，但它们都面临着同样的挑战：地球上建造的材料很难从月球表面运输到月球表面。欧洲航天局一直在试验使用风化层（覆盖月球表面的沙状物质）作为建筑材料，并已用乐高太空积木完成了概念验证。这些灰色砖块是 3D 打印的，用陨石尘埃代替风化层，虽然看起来有点粗糙，但它们拼合起来就像真的砖块一样，这表明类似的砖块可以在月球上打印和建造，从而无需花费高昂的成本将材料从地球运来运去。欧洲航天局太空积木将在部分乐高零售店和丹麦比隆的乐高之家展出至 9 月 20 日。

美国国家航空航天局在其整个历史中使用的标识和符号几乎与其成就一样具有标志性。这款黑色卡车式网帽采用其着名的标志设计，于1975年设计，绰号为“蠕虫”。该徽标于1992年退役，并用金色文字刺绣熨斗贴片装饰这顶帽子。这款5面板，高廓形后背帽采用轻质透气设计，为您的休闲外观增添怀旧气息。
