摘要
2023年4月至5月，superBIT望远镜由充氦超压气球升至地球平流层，以获取穿过（99.5%的）地球大气层的天文成像。它从新西兰发射，随后在40至50度南纬绕地球飞行五圈，历时40天。望远镜上搭载了四个“DRS”（数据回收系统）舱，内含5 TB固态数据存储，以及GNSS接收器、Iridium发射器和降落伞。望远镜数据被复制至其中，两个舱在阿根廷上空投下。它们在下降32 km的同时水平漂移61 km，但我们在2.4 km内预测了其下降矢量：在此地点，由于高速、阵风及局部地形，偏差似乎无法降至2 km以下。随后舱体将自身位置报告至数米精度。我们回收了舱体并成功取回superBIT的全部数据——尽管望远镜本身在着陆后被毁。
