Extraterrestrials on super earth may use “space airdropper” to propel rocket launch?!

Rocky planets larger than Earth are common in the Milky way, and some of them may harbor life, which raises an interesting question: how much gravity do such planets generate? How difficult is it for aliens living on these super earth planets to launch rockets into space? At present, according to a new study, it is not easy for aliens to launch rockets and spaceships from super earth planets Apollo Saturn V rocket weighs 3000 tons, and a rocket of the same level needs 440000 tons to launch on the…

Rocky planets larger than Earth are common in the Milky way, and some of them may harbor life, which raises an interesting question: how much gravity do such planets generate? How difficult is it for aliens living on these super earth planets to launch rockets into space? At present, according to a new study, it is not easy for aliens to launch rockets and spaceships from super earth planets

Apollo Saturn V rocket weighs 3000 tons, and a rocket of the same level needs 440000 tons to launch on the super earth, which is equivalent to the mass of the Great Pyramid of Giza in Egypt. It is very difficult for the aliens living on the super earth to escape from the gravity

如果有智慧外星人生存在这颗行星,他们将很难通过发射航天器离开这颗行星,因为超级地球的引力非常强” data-link=”” src=”/wp-content/uploads/2020/07/11/20200711_5f0a0593dc7b2.jpg”  /> is the artist’s description of kepler-69c, a super earth in the habitable zone of the Swan constellation, 2700 light-years from earth. </p>
<p> if intelligent extraterrestrial life exists on this planet, it will be difficult for them to leave the planet by launching a spacecraft, because the gravity of the super earth is very strong</p>
<p >It is reported that the extraterrestrial civilization living on a large rocky planet may be more difficult for them to explore space than for human beings on earth! A physicist has proposed a new “extraterrestrial rescue program” that claims that they have developed a space tether; A multi system, using a rotating orbit rope, can eject a spacecraft to a distant space region</p>
<p >Alex Howe, an astrophysicist at the University of Michigan and the author of the report, said: “when I first heard about a space tether, my first reaction was that it couldn’t work;</p>
<p >Super earth, super gravity</p>
<p >Usually, exolithic planets are more than 10 times larger than Earth, and they are often referred to as “super earth”; </p>
<p> they are the most common planets around other stars. Astronomers have discovered more than 1000 rocky planets so far. However, due to the strong gravity of rock planets, which can maintain a thick protective atmosphere to avoid cosmic radiation, some researchers speculate that the environment of rocky planets may be more conducive to the formation of life than the earth </p>
<p >A rocket must carry fuel, so every additional pound of propulsion fuel will make the rocket heavier, and the need for more fuel means that the rocket is heavier. This effect is called “rocket equation”;  <br /> therefore, although the Apollo Saturn V rocket weighs 3000 tons, a rocket of the same class needs 440000 tons to launch on the super earth, which is equivalent to the mass of the Great Pyramid of Giza in Egypt</p>
<p >For the technologically advanced alien civilization, the super earth may be a “trap”; According to statistics, the speed required for spacecraft to escape from the earth’s gravity is 40000 km / h, which is very fast, and also needs a lot of chemical rocket fuel Kepler-20b is a super earth planet 950 light-years away from the earth, and its mass is about 10 times of that of the earth. If kepler-20b is pregnant with advanced civilization, the escape speed (the flight speed that can be achieved by breaking away from the planet’s strong gravity) of spacecraft developed by aliens must reach 96000 km / h</p>
<p >Ejection into space orbit</p>
<p >In the latest research report published on May 16, Howe described an alien hybrid launch system. Instead of launching an off orbit spacecraft by rocket, the alien first placed a huge cable on its planet orbit. This cable, sometimes called “skyhook”, is thousands of meters long and slowly revolves around the center of the planet When the cable rotates, one end of the cable will fall toward the surface of the planet, which means that the range of the rocket launched into the air is shortened, perhaps 50-70 km, and the rocket hooks into one end of the cable; </p>
<p> Howe likens this effect to a lacrosse player hitting a ball at amazing speed with an extra long club</p>
<p >Although  quot; space airdrop  quot; </p>
<p> other proposed technologies, such as the 160000 kilometer high space capsule, require greater material strength than any currently known material He added that never built nuclear rockets require a more powerful engine than the chemical fueled rockets currently in use and are also considered a way to escape from the super earth However, the technology requires detonating a nuclear bomb under the spacecraft to generate power to drive the spacecraft to fly in the direction of space. The technology needs to eject destructive radiation material towards the ground, and requires very solid materials to keep the spacecraft as a whole</p>
<p >Avi Loeb, a theoretical physicist at the Harvard Smithsonian Center for Astrophysics, who was not involved in the study, said: ‘this is an interesting proposal. </p>
<p>   but he wants to know whether the  quot; arrogant space dropper program  quot; is worth pursuing by aliens to build  quot; space airdroppers; As a result, the super earth alien R  D team may more realistically consider more secure methods such as strong chemical reactions, using rocket fuel or launching nuclear rockets</p>
<p >Civilizations on the super earth may have other ways to launch spacecraft into orbit than conventional rockets, such as a space elevator running along a cable. </p>
<p> however, one of the limiting factors for space elevators is the strength of the cable material. </p>
<p> the most suitable material for space elevators is carbon nanotubes; </p>
<p> is not clear about the physical feasibility of materials with higher strength, so it is difficult to predict whether there is a space elevator on the super earth</p>
