Breakthrough Initiatives started its Starshot project in 2016 to combine nanometer-sized spacecraft with light sails, and in 2017, NASA began funding its own project targeted at launching a mission to Alpha Centauri by 2069, 100 years after Apollo 11.
While small spacecraft are easier to accelerate than larger probes, traditional fuel sources alone are not powerful or plentiful enough to push these craft to near light speed. Instead, Philip Lubin, a professor of physics at the University of California, Santa Barbara whose ideas for interstellar travel inspired the Starshot team, told Live Science that these craft will likely rely on light instead.
A similarly, momentum carried by light is transferred to the spacecraft, which causes it to recoil and accelerate." The system is basically a gigantic flashlight — it's a giant laser array [on Earth]," Lubin said. If the spacecraft are sailboats, then the laser light is the wind in their sails.
Technology to create and test these craft, such as communications equipment small enough to fit on them, is still being developed. But there's no physical reason to believe that such a spacecraft couldn't conduct a flyby mission of Alpha Centauri, Lubin said.
Such mission behave much like Voyager 1 & 2 probes transmit high-resolution images of the star system back to Earth, some of which might contain our first lookProxima Centauri's potentially habitable planet.
While Lubin stressed that a journey to Alpha Centauri would be a long-term endeavor, Eubanks said he's confident that big advances could come this century.
"I think, we'll reach Alpha Centauri system, with small probes launching in the decade of the 2040s, and thus arriving in the 2060s," Eubanks said. "Significantly larger probes should be possible by end century, but without unexpected breakthroughs in propulsion physics, I think crewed missions will be a task for the next century."

Ancient Star Seen Zooming Through Space at 600 Kilometers Per Second. Most of the stars in the Milky Way tread sedate and orderly orbital measures around the galactic center, but that's not the case for everything. "hypervelocity" stars are extremely rare". A star named CWISE J124909+362116.0 (J1249+36 for short) not only exceeds galactic escape with a velocity at around 600 kilometers (373 miles) per second
Proxima Centauri, the nearest star to our solar system, is approximately 4.24 light-years away from Earth, that means light, which travels at a speed of approximately 299,792 kilometers per second, would take roughly 4.24 years to travel from our planet to Proxima Centauri.

Recently discovered flaws in electronic circuits onboard NASA’s Europa Clipper spacecraft could threaten longevity or even the launch of $5 billion mission to explore Jupiter’s icy moon & ocean inside it. The packaged up probe continues to be prepared for an October flight from Florida’s Kennedy Space Center, a “tiger team” of engineers convened by space agency is reviewing the issue, with a report expected later this month.
Problem stems from a batch of circuit elements, called metal-oxide-semiconductor field-effect transistors, or MOSFETs, not meet the radiation-hardness standards set for mission. Transistors serve as amplifiers or switches, turning power off & on parts of spacecraft. But like all electronics, they can be damaged by high-energy radiation particles. & Clipper, as it flies past Europa some 50 times during its planned life, will repeatedly face Jupiter’s radiation environment, one of the harshest ever navigated by a NASA mission.
Engineers at NASA’s Jet Propulsion Lab (JPL), leads development of Clipper, discovered the problem in May after talking with colleagues about a classified satellite at a conference. They told the JPL staff a batch of radiation-hard MOSFETs developed by Infineon Technologies, a leading commercial supplier, was falling far below desired performance levels.
Concerns were passed along to NASA officials, 2 days ago briefed scientists on the agency’s independent planetary science panel. “We’re seeing some MOSFETs fail at lower radiation levels,” said Shannon Fitzpatrick, asso-director of planetary science flight programs, speaking on 9 July to NASA’s Planetary Science Advisory Committee (PSAC). “There is a risk these MOSFET transistors may not meet the radiation tolerance we require.” Radiation exposure has long been a central problem of exploring Jupiter & its moons. Jupiter’s magnetic field is (20,000 times stronger than Earth’s), and it spins rapidly, creating a torrent of bombarding charged particles. Europa mission, which will search the moon for evidence of habitable conditions in its subsurface ocean.

Last summer, while Northern Hemisphere endured record-breaking heat, a paper in Environmental Health Perspectives (EHP) generated a stir among scientists who study heat’s risks to health. Paper pointed out a startling disconnect between two camps of researchers on whether humidity makes hot weather more deadly.
Physiologists have found strong evidence that humidity matters: at a given temperature, more humidity makes it harder for the body to maintain a safe core temperature & ward off heat stroke. Epidemiologists, by contrast, have concluded that temperature alone accurately predicts heat-related death rates; adding humidity does little to improve their predictions?.
Before the EHP paper, “No one had directly said: ‘Look, these two fields are going along in parallel with entirely different conclusions,’” says its first author, climate scientist Jane Baldwin of the University of California, Irvine, who highlighted the conundrum at a Columbia University workshop on extreme heat last month. “And if this continues, this could be a real problem for projecting impacts of climate change.”

Einstein predicted an engine that would travel faster than light: It has been built for the first time, and it works like this.
This is the first immortal battery in history: Experts have hacked energy for the first time. Einstein got it right with his impossible proposition: Antimatter and gravity have started to do this
Lincoln would have loved to see it: This ingenious invention will save America from hurricanes forever.
A few days ago, we remembered the anniversary of man’s landing on moon, a feat achieved by US will not be forgotten, the last historic step has been taken by Germany, or rather, it taken decades ago, we did not know it: Einstein, the greatest physicist of all time, predicted a vehicle could travel faster than light, has always been considered science fiction. Against all odds, a team of renowned engineers laid groundwork now finally know that it is possible.

Einstein predicted an engine that would travel faster than light: It has been built for the first time, and it works like this
by D. García 07/30/2024
Einstein got it right with his impossible proposition: Antimatter and gravity have started to do this engine, Einstein engine, warp drive engine
Lincoln would have loved to see it: This ingenious invention will save America from hurricanes forever. What previously was on the shelves of the science fiction has become closer to real-world implementation due to recent developments in theoretical physics. The warp drive is also based on the law formulated by Albert Einstein, where nothing can travel with a velocity greater than the velocity of light.
Nevertheless, in the Scenario in Specific History, in the year 1994, a man from Mexico named Miguel Alcubierre describes a theoretical model in which the space-time fabric can be manipulated, as a result, a ship with sufficient mass energy can travel faster than light (remember that this is considered to be the theoretical limit).
https://www.ecoticias.com/en/einstein-predicted-plasma-engine/4992/
Recent research has shifted the focus from the traditional Alcubierre model to a more feasible approach: the “Constant Velocity Sub-Luminal Warp Drive.” This new idea is a contribution of a team from the Applied Physics, an international think tank, and the University of Alabama in Huntsville proposing a warp drive that can travel at sublight speeds without the use of such materials.
Experts are sincere about the “Einstein engine”: Why it should not be considered as science-fictional.

It’s all “exotic matter”: Einstein predicted it, and Hawking failed in its search:
The original Alcubierre drive was dependent on the use of “exotic matter,” which is a negative energy density that is yet to be identified in any way and can be greatly considered as just a theory. The energy demanded for such a drive was also reportedly mind-boggling, and calculated to be in the order of the mass energy of a planet like Jupiter.

They went to space for eight days - and could be stuck until 2025.
When two American astronauts blasted off on a test mission to the International Space Station on 5 June, they were expecting to be back home in a matter of days. But things didn't quite go to plan.
In fact, Barry “Butch” Wilmore and Sunita Williams are still there, floating high above the Earth nearly two months later.
The pair - who are stuck indefinitely - now face the sudden prospect of missing the summer entirely and even spending Christmas and New Year in space....

A colonial world: Starting in 1462, eight Western European countries (⬤shown in orange)—the United Kingdom, France, Germany, the Netherlands, Belgium, Spain, Portugal, and Italy—began to colonize other continents. By 1700, European powers occupied much of the Americas. By 1900, most countries in the Americas had gained independence, and European nations focused their colonial efforts on Africa and Asia.
The legacy of colonialism contributes to global inequities in many aspects of society today, including science.

September 9, 1776, the 2nd Continental Congress adopted a new name for what had been called the "United Colonies.” The moniker United States of America has remained since then as a symbol of freedom and independence.

History of the lands became United States began with the arrival of the first people in the Americas around 15,000 BC. Numerous indigenous cultures formed. After European colonization North America began in late 15th century, wars epidemics decimated indigenous societies.
Starting in 1585, British Empire colonized first, the Atlantic Coast, and by 1760s, the thirteen British colonies were established.
The Southern Colonies built an agricultural system on slave labor, enslaving millions from Africa for this purpose. After defeating France, the British Parliament imposed a series of taxes, including the Stamp Act of 1765.
Resistance to these taxes, especially Boston Tea Party in 1773, led to Parliament issuing the Intolerable Acts designed to end self-govt. Armed conflict began in Massachusetts in 1775.
