For several decades, we have been gradually exploring the secrets of our nearest cosmic backyard Solar System. We know that with the sun we are in the so-called heliosphereits boundaries are determined by the prevailing solar wind pressure over the galactic winds. This is our protective bubble they are in All the planets of the solar system.
In 2012, Voyager 1 crossed the heliosphere, and thus the limits of the described heliosphere. Thus, it became the first man-made space probe to enter interstellar space. 10 years have passed since then, and scientists are dreaming of the next mission.
It doesn’t matter where we’re going. It’s about traveling there. It is a long-awaited trip. – says the physicist Raplh McNutt Jr. From the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland.
Interstellar mission for both Voyager probes It’s a coincidence. Both were set up to study the solar system. No one expected that 45 years after being launched into space, they would still be transmitting valuable scientific data. But scientists need something more prepared for an interstellar mission. New hopes are born on the horizon as the horizon evolves space launch system (SLS) by NASA.
Scientists have developed the concept of the probe interstellar probe, whose goal will be to reach several hundred AU from Earth, providing new measurements of conditions in the heliosphere and beyond. It would kind of ‘take the lead’ in the relay he started with Voyager probes and Pioneer 10 . probe.
Humanity already has the right technology to make it Take space probes very long distances. With SLS, we should be able to ship Double the speed of Voyager 1 (about 7.2 lei per year).
Voyager sensors Powered by thermoelectric generators that contain almost radioactive isotopes 4.5 kg of plutonium-238. They gain energy to work through the cause radioactive decay of plutonium. However, this process will also end at some point. The expected power to power the Voyager probes will be enough until 2025. Until then, humanity will have scientific data about interstellar space, and what will happen next? may be next The interstellar probe, promoted by McNutt.
I think the interstellar probe is an excellent concept. – Values Paul Gilster, Creator of Centauri Dreams. It’s a mission that can take us Up to 1,000 AU over 50 years, which creates the possibility of observing the heliosphere from the outside. – added in an interview with Space.com.
Sending such a probe into space at present will pay off Much more scientific information than the Voyager probe. The stellar probe will take care of collecting scientific data along the way. Thanks to it, according to Gilster, mankind will have the opportunity to study, for example, Oort cloud from which comets come to uswhich is currently not actively explored.
