Moon missions come in all shapes and sizes, from car-sized rovers packed with scientific equipment to towering rocket payloads—and now, a small, shape-shifting machine that is about the size of the average palm.
Binary asteroid systems are widespread throughout our inner solar system. For decades, the standard paradigm held that many of them form when a rapidly spinning primary asteroid casts off material, which then reaccumulates ...
Heat waves across Europe and South Asia have dominated the news recently. But these events are really a surface expression of more fundamental changes affecting our planet: Earth itself is accumulating heat faster than ever ...
