Imagine a place like our solar system. A place with a ‘central’ star orbited by planets but light years away. There might be a planet there with water and living organisms. Now imagine if you could get there somehow and see it and analyze it. For many years, humans have sent probes into space, with one of The latest being NASA’s InSight Mission, which you can find out more in one of my latest articles here .

It took the InSight probe about 7 months to get to Mars. Mars is about 34, 647, 420 miles (55, 757, 930 km) from our Home Planet. But what about Alpha Centauri, the closest star system to us? It’s a whopping ~ 25, 000, 000, 000, 000 (trillion) miles from our home planet. d take anywhere between 1,000 to 81,000 years to get to Alpha Centauri. This neighboring star system consists of three stars, Alpha Centauri A, Alpha Centauri B and Proxima Centauri;

But, an international team of scientists have come up with a way of sending a probe to Alpha Centauri in just over 100 years ]een factor van een of twee kleiner dan de huidige ETA voor een theoretische probe die was verzonden met de huidige technologie. The team proposes a probe that would be powered by lasers, something known as a laser sail. Laser sails are structures that consist of a reflective surface which, if illuminated with a laser, can cause the structure to move via the transfer of momentum from the reflected photons to the structure. These light sails are often used in spacecraft propulsion because the sun is a useful source of photons that can be used to propel a structure. Another useful sail that is used in spacecraft propulsion is magnetic sails. Magnetic sails work by having loops of superconducting wires which produce their own magnetic field. Når den magnetiske sail interagerer med de ladede partikler i rummet, forårsager de at deflektere de ladingspartikler og momentum er overført fra sagen til de partikler, der forårsager at sagen til langsomt ned. Thus, magnetic sails are normally used to slow down spacecrafts.

As part of the British Interplanetary Society workshop back in July 2015, teams of scientists presented their ideas of how they thought they could send a probe to Alpha Centauri within about 100 years. An ide proposed by a team of scientists from Cranfield University in the UK, UPS in France and the Skolkovo Institute of Science and Technology in Russia, which make up the CranSEDS team involved laser and magnetic sails. The idea involved using lasers that gave a total output power of 100 GWs (100, 000, 000, 000 Watts) to propel a ~ 6000 lbs (2750 kg) of spacecraft to about 5% of the speed of light. This gave an ETA of about 100 years from now. The size of the sail would be about 18.26 miles (29.4 km) which requires a laser with a diameter aperture of the same size. The sail would be made of a graphene monolayer, where graphene is a monolayer of carbon atoms arranged in hexagonal structures. Målet er at ligge på enten Earth-Sun L1 Langrange punkt eller i Cislun-bane, som så ville skinne på rumfartøjet og ville blive drevet af store solpaneler. A magnetic sail would be unleashed to slow down the spacecraft near its destination. You can find out more details about the laser-powered probe here & nbsp; and the Science Direct Paper here .

With the combination of both laser and magnetic sails the team hopes to reach Alpha Centauri in about 100 years. So, watch this space and maybe one day our children or grandchildren will see images or data from Alpha Centauri.

It’s a whopping ~ 25 , 000, 000, 000, 000 (trillion) miles from our Home Planet. It is estimated that it could take anywhere bet wean 1,000 to 81,000 years to get to Alpha Centauri. This neighboring star system consists of three stars, Alpha Centauri A, Alpha Centauri B and Proxima Centauri; where Proxima Centauri is the closest star to Earth that exists outside of our solar system.
