EXCERPT: . . . Though exact timeframes tend to differ, a 260-day trip to the red planet seems the closest to a consensus among those knowledgeable of the journey, meaning it would take nearly nine months to reach its orbit. However, according to UC Santa Barbara physics professor Philip Lubin, by making use of directed energy propulsion (i.e. lasers) it might be possible to reach Mars in a fraction of the time it would take to watch "The Martian". [...] Amid the many paragraphs of scientific jargon, experimental equations, and detailed set of planning, Lubin maintains this isn’t some far-off idea, but rather, something that’s attainable this very second....
