Why was NASA's Artemis mission postponed?

NASA postponed the Artemis launch. The reason for that is, that they wanted to be sure that this mission will be successful. It would be embarrassing if the Orion mega-booster will detonate on the launch pad. The key element in the Artemis mission is "Orion". That booster is the most powerful rocket ever created by NASA. And this rocket involves brand new technology that has never been used before.

So Artemis is much more than some moon program. It offers a framework for many R&D projects. NASA can use the "Orion" booster in heavy missions. And one of those missions is to launch heavy satellites in higher orbiters. Also if NASA makes a manned Mars flight in the future, that mission requires a heavy booster to rise nuclear reactors to the Moon orbiter.

If the nuclear rocket will put together and launched from the Moon orbiter that denies radioactive debris fall to Earth. But that kind of mission requires a heavy-duty booster.

The U.S. military is concerned about the possibility that low-orbit satellites will be good targets for ASAT weapons. And therefore, the military authorities want to raise reconnaissance and GPS satellites to higher altitudes.

But if the satellites are used for photo-recon missions that require larger optics. And those satellites are extremely heavy. Orion boosters can use to launch those large-size satellites to higher altitudes, where they are better protected against ground-based lasers and ASAT missiles.

Artemis is a new concept. It has powerful AI and solar panels. Which are decreasing the use of fuel. The advanced power supply systems are making those capsules more capable than ever before.

When brand new high-pressure technology is tested. Engineers must make them using very high accuracy. If something goes wrong there is the possibility that the booster will detonate. And that thing is not very good for missions that are planned for Orion and Artemis.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
