“The invention, which cooks cylinder-shaped pizzas and other foods, recently moved on to the final phase of NASA’s Deep Space Food Challenge.”
The invention, which cooks cylinder-shaped pizzas and other foods, is now being adjusted for zero-gravity with the help of BioServe Space Technologies.
Only by expanding the domain of life into space can we fulfill the 17 SDGs on Earth in the long term. Therefore, the Space Renaissance International and the…
Since the 17th century, when Isaac Newton and Christiaan Huygens first debated the nature of light, scientists have been puzzling over whether light is best viewed as a wave or a particle—or perhaps, at the quantum level, even both at once. Now, researchers at Stevens Institute of Technology have revealed a new connection between the two perspectives, using a 350-year-old mechanical theorem—ordinarily used to describe the movement of large, physical objects like pendulums and planets—to explain some of the most complex behaviors of light waves.
The work, led by Xiaofeng Qian, assistant professor of physics at Stevens and reported in the August 17 online issue of Physical Review Research, also proves for the first time that a light wave’s degree of non-quantum entanglement exists in a direct and complementary relationship with its degree of polarization. As one rises, the other falls, enabling the level of entanglement to be inferred directly from the level of polarization, and vice versa. This means that hard-to-measure optical properties such as amplitudes, phases and correlations—perhaps even these of quantum wave systems—can be deduced from something a lot easier to measure: light intensity.
“We’ve known for over a century that light sometimes behaves like a wave, and sometimes like a particle, but reconciling those two frameworks has proven extremely difficult,” said Qian “Our work doesn’t solve that problem—but it does show that there are profound connections between wave and particle concepts not just at the quantum level, but at the level of classical light-waves and point-mass systems.”
Meet XRISM, the telescope collaboration between JAXA and NASA that could reveal the universe’s secrets.
Following several launch delays last week, the week of Aug. 21 through Aug. 27 is set to see seven launches marking the 129th through 135th orbital launch attempts of 2023.
Starting the week off, SpaceX will launch two back-to-back Starlink missions from Space Launch Complex (SLC) 4 East at the Vandenberg Space Force Base (VSFB) and from SLC-40 at the Cape Canaveral Space Force Station (CCSFS). Next, Russia will launch its Progress resupply mission, followed by Rocket Lab’s launch of “We Love the Nightlife.” SpaceX will then launch the Crew-7 mission from Launch Complex 39A (LC-39A); JAXA will launch the SLIM and XRISM mission; SpaceX is expected to end the week off with another Starlink mission from SLC-40.
A type 5 civilization often seen as unattainable is actually quite possible. We could have computers to use a developer mode to solve all sorts of problems like the entropy of the universe and even stop the entropy of the earth or stop meteorites from hitting earth with a computer click. This could easily be attainable with technological singularities leading to a new understanding of our universe but should be considered to essentially stop almost any problem to earth and beyond.
Type 1 civilization designation on the Kardashev scale may be possible in the next 100 years, which could influence the survival of mankind.
Texas A&M University’s board of regents voted to approve the construction of a new institute in Houston that hopes to contribute to maintaining the state’s leadership within the aerospace sector.
This week, the Texas A&M Space Institute got the greenlight for its $200 million plan. The announcement follows a $350 million investment from the Texas Legislature. The institute is planned to be constructed next to NASA’s Johnson Space Center in Houston.
“The Texas A&M Space Institute will make sure the state expands its role as a leader in the new space economy,” John Sharp, chancellor of the Texas A&M System, says in a news release. “No university is better equipped for aeronautics and space projects than Texas A&M.”
Instruments in different parts of the solar system all captured radiation from the same coronal mass ejection for the first time ever.
The universe is not static or silent, as is commonly believed. It moves, expands and… vibrates. And this is where gravitational waves play an important role: tiny ripples in the fabric of space and time that occur when massive objects accelerate or collide.
Gravitational waves are generally very difficult to detect because they are usually very short and weak, and get lost in the background noise of the universe.
For this reason, until now only some of them have been captured with very sensitive instruments such as the Laser Interferometer Gravitational-Wave Observatory (LIGO), which measures the distortions caused by the waves in two laser light beams separated by kilometers.
NASA has chosen Lockheed Martin to test a nuclear-powered rocket in space by 2027, in hopes of using the system to power Mars missions.
