- NASA’s Future Spaceships Will Travel At 1 Million Miles Per Hour
Two highly promising concepts are being funded by the NASA Institute for Advanced Concepts (NIAC). In terms of ISP and power levels, the new ion drives could have been five times better. The development of multi-megawatt ion engines and antimatter propulsion is ongoing. Propulsion and Speed in Space What is the fastest spacecraft we have made? Voyager 1 is travelling at a speed of 38,000 mph (61,000 km/h). Both a gravitational slingshot and a chemical rocket were mostly used to accomplish this. Using gravitational boosts, the Juno, Helios I, and Helios II spacecraft attained speeds in the 150,000 mph range. The Sun's gravity will let the recently launched Parker Solar Probe travel at 430,000 miles per hour. Gravitational acceleration can increase the speed of a spacecraft by many times. However, using the gravity of Jupiter and the Sun to get more speed waste a lot of time. The spacecraft take many months to go around the Sun and get speed before starting the real mission. Best Chemical Rocket Speeds and Times Refuelling a large rocket like the SpaceX BFR can produce surprisingly good trip times to Mars. Multiple orbital refuelling of the SpaceX BFR at a high orbit can maximize the speed of the BFR. A fully fuelled SpaceX BFR would shorten the one-way trip to Mars to as little as 40 days. A parabolic orbit would be used instead of a Hohmann transfer. Space Missions to Mars have been small spacecraft. The entire mission was launched from Earth. This means most of the fuel was used to get the system off of the Earth. The final stage is tiny and slow. By refuelling the SpaceX BFR in orbit, it is possible for a large chemically powered space mission with up to 10.0 kilometre per second Delta-V. This is about 100 hundred times larger than prior Earth to Mars missions and three times faster. Advanced Propulsion: Multi-megawatt Lithium-ion Drives JPL (Jet Propulsion Lab) will be testing a 50000 ISP lithium ion thruster within 4 months. This is part of a NASA NIAC phase 2 study to use lasers to beam 10 megawatts of power to new ion drives. Many people are not aware of the recent progress with more powerful lasers. The US military is developing arrays of lasers that can produce 100 kilowatts within the next 2 years. The military should have megawatt laser arrays by around 2025. Laser beam-powered lithium-ion drives ten times faster than any previous ion drive. A spacecraft with this system would take less than a year to get to Pluto. JPL is building and proving the various components of this system. The sail and the ion drives are coming together. The hard part is the phased array lasers. They are boosting the testing voltage up to 6000 volts so the lithium-ion drives can be directly driven. Direct drive eliminates the need for a lot of heavy electronics which would kill the performance. The power density will be one hundred times more than sun-based solar power. They will reduce system size by using a laser wavelength of 300 nanometers instead of 1063 nanometers. The multi-megawatt lithium-ion drive has technical challenges. However, a well-funded project can be successful before 2040. Advanced Propulsion: Positron Dynamics – Positron Catalyzed Fusion Drive Positron Dynamics has given updates to NIAC and Brian Wang has interviewed Positron Dynamics CEO Ryan Weed. The problems to create and store antimatter are avoided. Krypton isotopes are used to generate hot positrons. More isotopes can be made using neutron-producing reactors. This avoids the problem of creating antimatter. Antimatter is not stored, which is great because we do not know how to store antimatter. Positrons are created and then directed into a process that produces fusion propulsion. This also solves the problem of using antimatter to generate propulsion. Positron Dynamics slow the positrons that are generated. They have a small moderator device. It uses several layers of silicon carbide film to extract individual positrons. An electric field causes the particles to drift to the surface of each layer where they can cool. The positrons catalyze fusion reactions in a dense block of deuterium. This produces propulsion.
- American Scientists Suggest an Extraterrestrial Meeting by 2030, Revealing the Truth Amidst Growing
In recent years, the possibility of extraterrestrial life has captivated the imagination of scientists and the public alike. While the existence of aliens has been the subject of debate for decades, a new wave of speculation has emerged, claiming that American scientists are convinced we will make contact with extraterrestrial beings by the year 2030. According to these rumors, the truth about the existence of aliens will finally be unveiled, as the risks associated with keeping such a monumental secret become too great to bear. Traditionally, the idea of encountering intelligent life beyond Earth was relegated to science fiction. However, with advancements in technology, the discovery of exoplanets, and the ongoing search for microbial life on Mars, scientists have begun to ponder the possibility of sentient beings residing elsewhere in the vast cosmos. This paradigm shift has spurred new initiatives, such as the Search for Extraterrestrial Intelligence (SETI) and the Breakthrough Listen project, which are dedicated to detecting and deciphering potential extraterrestrial signals. Rumors of a secret operation involving American scientists have been circulating within scientific circles and online forums, suggesting that significant progress has been made in contacting and establishing communication with extraterrestrial civilizations. Anonymous insiders claim that a clandestine organization, operating under the auspices of the United States government, has been collecting and analyzing data obtained from unidentified aerial phenomena (UAPs) for decades. While secrecy surrounding sensitive scientific research is not uncommon, the potential ramifications of withholding the existence of extraterrestrial life from the public have been a cause for concern among a group of American scientists. In recent years, there has been an increase in public interest and scrutiny surrounding unidentified aerial phenomena, leading to mounting pressure on government agencies to disclose any information they may have. Maintaining the secrecy indefinitely has become an untenable position for those involved, given the potential consequences of such a revelation. The rumored disclosure in 2030 would undoubtedly have profound scientific and societal implications. From a scientific standpoint, confirmation of the existence of extraterrestrial life would revolutionize our understanding of the universe. It would spark an unprecedented wave of interdisciplinary research, bringing together astrophysicists, biologists, anthropologists, and many others to study and comprehend these newfound life forms. Societally, the impact would be equally significant. The knowledge that we are not alone in the universe could shift our collective perspective, fostering a greater sense of unity and interconnectedness among humanity. However, the revelation could also raise questions about our place in the cosmos, our origins, and the implications for our future as a species. While the scientists rumored to be involved in the secret operation recognize the need for disclosure, they also acknowledge the importance of proceeding with caution. Potential risks associated with the revelation include societal upheaval, religious and philosophical conflicts, and the destabilization of global power structures. To mitigate these risks, a carefully planned and managed disclosure process would be necessary, ensuring that the public receives accurate and comprehensive information while minimizing panic and confusion. The prospect of meeting aliens and the subsequent disclosure of their existence to the world is a topic that continues to captivate the collective imagination. While rumors persist regarding American scientists and their alleged plans for contact by 2030, the truth remains uncertain. However, it is undeniable that the increasing risks associated with maintaining a secret of this magnitude have sparked discussions among scientists and the necessity of a future disclosure. Whether we will indeed meet extraterrestrial beings in the near future or not, the quest for knowledge
- Astronaut “breaks the silence about aliens and humanity”
When it comes to astronauts, there is no shortage of those who have spoken about the UFO phenomenon. And most of them have been raising awareness about aliens and humanity for years. Gordon Cooper , an aerospace engineer, and one of the original seven astronauts of Project Mercury is a great example. He’s been quite frank about UFOs, aliens, and the fact that the agency is and has played a huge role in the cover-up. Former Princeton physics professor and NASA astronaut Dr. Brian O’Leary is another great example. He told the world for years that “there is abundant evidence that we are being contacted, that Alien civilizations from other worlds have been visiting us for a long time.” The sixth man to walk on the moon, Dr. Edgar Mitchell, is also no exception. Before his recent passing, Mitchel spent years raising awareness about the fact that UFOs are real, and that some are not from our planet, but from other solar systems, or other dimensions. Again, the list is long and goes far beyond the testimony of astronauts and NASA personnel who have “opposed” the firm position of the US agency. Why does astronaut Story Musgrave appear at a UFO conference? Musgrave is known as the most educated astronaut, he is a doctor (MD) and also has six academic degrees. He is also the only astronaut who was on board all five space shuttles. Some time ago he gave an interesting lecture while talking about the UFO phenomenon. But unlike astronauts like Mitchell, for example, he’s always careful to say that he doesn’t have much evidence for what he’s saying. This means that it is a shield so that it cannot be chased. But he does speculate, with a sharp gaze when he makes the following statement. He bases his hypothesis on his “observations” and “what he has been exposed to.” Astronaut Story Musgrave gave an important key in his lecture saying that, if we look at technological development, it does not make sense that in a matter of 50 or 70 years we have advanced what we could not in thousands of years, always speaking of our species as such. He also commented that every time he was in space, he could see an infinity of unknown ships or unknown phenomena around him, a custom that was no longer surprised throughout the missions carried out. Story said that “if you look at some planet, and some creatures that put it together, they could build technology for millions of years, this means that they are making stellar journeys to reach our planet, and with an ironic plan on their face and their words said , that’s how good they are, so … I have no proof … ” The great revelation was when he commented in his conference that “he has the certainty in his own being, that there are millions of people all over the world making star trips. Interstellar travel, for me, continues. “
