The old habit of leaning on chemical rockets for space travel might not keep up, as researchers keep digging into other propulsion ideas. Newer papers basically try to bend the laws of physics a bit, looking for more efficient, sustainable ways to get up to orbit, and then farther out too. If these non-rocket notions pan out, they could end up changing the way we reach the cosmos, cutting the price quite a lot and also lowering the environmental harm.
