Nuclear-powered rockets set to slash journey time to mars by 50 per cent: Report
British company Pulsar Fusion has revealed its plan for the Sunbird, a nuclear fusion-based rocket aiming to drastically cut space travel times.
The Sunbird is to send spacecraft to far-off places in space at record speeds using nuclear fusion, and it can be a very important step towards changing human transportation and space travel forever.
Pulsar Fusion's Sunbird is a quantum leap ahead in space propulsion technology. Although much technical innovation still lies ahead, the promise of fusion rockets is a giddy vision of space travel in the future. If successful, the Sunbird would revolutionize the manner in which human beings explore the cosmos, allowing for interplanetary travel faster and more affordable than ever.Nuclear fusion, the energy source of the Sun, has long been a thinkable power source for traveling into space. The achievement has however been found to be very hard to achieve on our planet. Richard Dinan, founder and CEO of Pulsar Fusion, described the natural difficulty in performing fusion on Earth as, "It's very unnatural to do fusion on Earth." He further stated that space is the natural environment for fusion because the conditions there are conducive to the process. In concurrence with Dinan, space provides the ideal environment for fusion, in which it occurs naturally and efficiently.Sunbird's propulsion system is fueled by a new technology called the Duel Direct Fusion Drive (DDFD). The engine uses a combination of helium-3 and deuterium to produce propulsion. In contrast to traditional fusion reactors, where energy produced must be converted to thrust, the DDFD produces charged particles that can be converted for propulsion. This breakthrough could make space propulsion much more efficient, giving a more direct and powerful method of traveling through space.One of the most exciting promises of the Pulsar Fusion technology is its potential to greatly reduce space travel times. The firm claims that the Sunbird would reduce travel to Pluto to just four years—a staggering reduction in travel times from what is currently achievable. The Sunbird would also halve journey time to Mars, enabling human missions of long duration. But it should be noted that so far, no space experiments with fusion have been performed, and these claims are therefore hypothetical and to be proven in practice. Challenges of Development and the Future AheadAlthough Sunbird is at its infancy stage now, Pulsar Fusion has set its target for achieving fusion in space by 2027. The journey to achieve that is not without a few very serious challenges. Pulsar Fusion will need to hurdle some serious engineering challenges to make this technology go mainstream. But if they succeed, the Sunbird can transform human exploration of the solar system.The Sunbird and similar rocket-powered fusion missiles are not to be launched from Earth. Because they are so powerful, it would not be possible to launch them from Earth. Their primary purpose would be in space, where they can intercept other spacecraft and launch them on trips between planets. The Sunbird might capture a spacecraft after being inserted into low-Earth orbit and transport it to destinations like the Moon or Mars, or beyond.First, Sunbirds will be used on cargo transport satellites in space to provide a more efficient and more powerful way of transporting objects from place to place in space. But the greatest potential of fusion-powered rockets lies in reducing travel time for interplanetary missions. With the capability of dramatically reducing travel times, fusion rockets can potentially make human missions to distant planets like Mars a possibility in the near future.
