NASA is testing a new space propulsion concept. It is assumed that the PBP engine will allow even heavy ships to leave the solar system in record time. Voyager 1 achieved this only after a long 35 years.
The American space agency NASA is working on a new type of space probe engine. The goal is to significantly reduce the time it takes a spacecraft to leave the solar system. This should allow humanity to explore the universe much more widely.
Pellet-Beam Propulsion is NASA’s propulsion for interstellar travel.
In early 2023, NASA provided a $175,000 grant to develop the Rocket Beam Engine, or PBP for short. Although scientists have yet to build the first prototype, the idea is already quite promising.
Theoretically, PBS engines could reduce the time spent outside the Solar System by up to 5 years. It is worth recalling that the historic space probe Voyager 1 only succeeded after 35 years in a vacuum. This would mean that manned flights beyond our planetary system could become a reality in the future. The chemical fuels currently in use simply cannot provide this.
How does the NASA Pellet-Beam Propulsion Engine concept work?
How does PBP work? The concept is based on an earlier Starshot initiative that aimed to develop so-called solar sails. In this system, very light probes are “pushed” off the Earth by millions of lasers that are aimed at a vehicle moving away from our planet.
However, Starshot’s limitation was the reduced weight of the probe as much as possible. Large and heavy vehicles are needed to explore and even colonize other planetary systems.
So the Pellet-Beam Propulsion system is based on the concept of solar sails, but a bit more advanced. When you send a PBP probe to a job, you need to start two devices. The first of them will be launched into the orbit of the Earth, the second will eventually fly into the unknown Universe.
The task of the orbital probe is to accurately send the capital “pellets” - microscopic particles of fuel that must regularly fall into the research probe. During their journey, the particles are also further heated by a grid of lasers fired from the Earth’s surface. This will allow the pellets to partially turn into plasma in a process called laser ablation and begin to accelerate even more.
Two things can happen after you get close to the probe. Ideally, the bead would hit the probe’s solar sail and accelerate it directly. However, even with less precision, the particle will also repel the device thanks to the field-generating magnets that will be placed inside the sail.
