Theoretically, alien contact should be expected from 2029

We advise you not to risk this information yet and do not start cleaning the house just because you will have guests from other solar systems. But a study published in the journal Publications of the Astronomical Society of the Pacific, a study co-authored by two University of California astrophysicists, says that, mathematically speaking, we should be contacted by intelligent aliens by 2029.

The idea is quite simple and starts with the radio signals that mankind has been sending into outer space for centuries. However, they are not discussed in the study. These signals are relatively weak and tend to diminish as one moves through space. By default, the chances of being intercepted by someone or something are relatively small. In conclusion, if you were thinking of asking ET when he is coming, if he is from FCU Craiova, FCSB, Rapid or CFR Cluj, better leave it.

The idea is that there are still some signals, some much stronger, that have already reached possible destinations where they can be intercepted. These are signals transmitted through NASA’s Deep Space Network (DSN) antenna system, a system designed specifically for space communications.

In case you didn’t know, the DSN transmitters were used to keep in touch with Voyager 1 and Voyager 2, which have already left our solar system, as well as Pioneer 10 and New Horizons, which are at the edge of our solar system. systems.

As you might suspect, these radio signals don’t stop when they hit space probes. No! They move on. Well, this is where the calculations of the astrophysicists I mentioned come into play. According to their data, the radio signals that were sent to the Pioneer 10 probe have already reached the solar system with a white dwarf located about 27 light years away, quite interesting and with a hypothetical chance of life.

If there are beings out there that have reached the level where they can use radio waves, and if they intercept our message, and if they choose to respond, and if they do, then we should receive their message by 2029.

If there is nothing there, we redirect to the Voyager probes. The signals sent to them reached some stars around 2007. One is at a distance of 26 light years from us, the other is at a distance of 24 light years. We resume the “what if” series and learn that we may be contacted after 2030, but not much later than that, so don’t plan your vacation just yet.

Obviously, this is the most optimistic scenario, which has a small chance of becoming a reality, that is, aliens will contact us. There is a possibility, obviously, that all the above conditions are met and we are missing the message. This would be the most pessimistic scenario, even lower than where we say we are alone in the universe. Or the horrible one we say we weren’t, but now live in a vast cosmic graveyard.

All in all, The UC Boys Study is an interesting game of imagination, complemented by simple mathematics. But it inspires hope. Until then, we have other serious issues to deal with. For example, have you seen how many kilograms of onions there are?

China strikes again and announces its most ambitious space communications project yet

If we still remembered radio signals and transmissions through space, we cannot miss one of the news of the moment. In particular, in an already exciting space race, China announces that in 2030 it will complete a gigantic project to launch a veritable “constellation” of satellites to provide communication between a lunar base and Earth.

The first “brick” in this project is called Queqiao-2, and it is a satellite that will establish radio communication with probes on the dark side of the Moon. Queqiao-2, by the way, will be launched next year. What probes are we talking about? Well, first, the Chinese say, it’s about the Chang’e-6 mission, which will launch next year and which aims to deliver samples of lunar soil from the dark side of our natural satellite.

In two years, the Chang’e-7 mission will explore the south pole of the Moon in search of resources for a future lunar base. The base, which, if all goes according to plan, should be built between 2030 and 2040, when China hopes to send the first taikonauts to the moon.

Also, by that time, the satellite system should be ready to provide communication between the base and the Earth. In addition, they will also be used for future missions targeting the planets Venus and Mars. Ah, did someone tell them that aliens might arrive then? Maybe they have more advanced technology and they will save money. Yes, but what if aliens befriend Americans? So the Chinese better do their own thing to be sure.

After Elon Musk’s chaos, US launch pads will be overhauled

As we previously told you, Elon Musk’s SpaceX is the subject of a federal investigation after it destroyed its Boca Chica, Texas, launch pad, narrowly avoiding exploding the base’s fuel tanks and endangering some of the turtles and birds that nest there. they forgot to warn that the worst missile in history was about to be launched.

Essentially, more than 30 Starship rocket engines made a crater several meters deep on the launch pad and threw chunks of concrete for miles. Elon Musk later stated that it was a miscalculation and he thought the platform would hold up. He did not resist.

So one of the first decisions made by the Federal Aviation Agency, the agency leading the investigation, was to modify the missile launch pads to make them more stable, and some to be equipped with fire-damping platforms and more. another that comes with a rocket launcher like the Starship.

Obviously, not all ramps will be modified. Some, like the Kennedy Space Center in Florida, already have everything they need. Elon Musk is expected to bear the costs of improving the bases provided to him. What the man promised to do in record time. Others would take care of the rest because they didn’t win it in belciuge to fix all their grievances.
