NASA's NEW Nuclear Engine to visit Mars in Day, Faster & Better Starship!
NASA's NEW Nuclear Engine to visit Mars in Day, Faster & Better Starship!
There are many reasons why humans have never explored Mars.
In fact, reaching the red planet, on average around 140 million miles away, will be a mammoth feat.
Colder than Antarctica and with little to no oxygen, Mars is a hostile environment. The longer it takes astronauts to get there and the longer they stay, the more they are at risk.
A roundtrip mission to Mars would last at least an astonishing 21 months: nine months to get there, three months on the planet, and another nine to get back.

Well, are you willing to do this?
But what if there were a faster way to get there? Even more than that of the SpaceX Starship.
Let’s find out on today’s episode of Alpha Tech:
Most rockets today run on conventional chemical fuels.
The trouble is, that all such propellants have a relatively small “energy density” (energy stored per unit volume) and a low “specific impulse” (the efficiency with which they can generate thrust). This means that the overall thrust of the rocket – the specific impulse multiplied by the mass flow rate of the exhaust gas and Earth’s gravity – is low.

Chemical propellants can therefore only get you so far, with the Moon being the traditional limit. To reach distant planets and other “deep-space” destinations, spacecraft usually exploit the gravitational pull of multiple different planets. Such journeys are, however, circuitous and take a long time. NASA’s Juno mission, for example, needed five years to get to Jupiter, while the Voyager craft took more than 30 years to reach the edge of the solar system. Such missions are also restricted by narrow and infrequent launch windows.
