如果你能绕火星飞行呢？上个月，美国国家航空航天局（NASA）的“毅力号”（Perseverance）登陆火星，可能已经实现了这种能力。“毅力号”上有一个适合飞行的小伙伴，名叫“独创性”（Ingenuity），绰号金妮（Ginny）。尽管金妮很小——一个烤面包机大小的直升机，有四条长腿和两个更长的（1.2米）旋翼，但她是第一个这样的直升机——以前从未有过像她这样的东西。在被部署后，可能在4月，汽车大小的毅力（“珀西”）将后退，给金妮足够的空间来尝试她前所未有的第一次飞行。在这幅特色的艺术插图中，金妮的长转子被描绘成让她飞进火星稀薄的大气层，探索毅力附近的地区。虽然独创性本身不会飞得很远，但它是未来所有机载太阳系机器人的原型，不仅可以飞越火星，还可以飞越土卫六。

What if you could fly around Mars? NASA may have achieved that capability last month with the landing of Perseverance, a rover which included a small flight-worthy companion called Ingenuity, nicknamed Ginny. Even though Ginny is small -- a toaster-sized helicopter with four long legs and two even-longer (1.2-meter) rotors, she is the first of her kind -- there has never been anything like her before. After being deployed, possibly in April, the car-sized Perseverance ("Percy") will back away to give Ginny ample room to attempt her unprecedented first flight. In the featured artistic illustration, Ginny's long rotors are depicted giving her the lift she needs to fly into the thin Martian atmosphere and explore the area near Perseverance. Although Ingenuity herself will not fly very far, she is a prototype for all future airborne Solar-System robots that may fly far across not only Mars, but Titan.
