Remote sensing is the imaging of Earth from space. It is incredibly valuable for environmental, national security and commercial purposes. Unfortunately, it’s governed by an outdated law that’s in desperate need of updating. Initially, remote sensing technology was only used by government agencies for national security and scientific research. However, in the 1990s, private companies

Mission accomplished: the Planetary Society announced Wednesday that its LightSail 2 spacecraft, which was launched last month, had successfully raised its orbit using only the power of photons from the Sun. The team behind the $7 million (roughly Rs. 48 crores) crowd-funded venture said they had demonstrated a proof of concept for a new form
Chase Dekker gripped his camera with anticipation. A couple hundred feet from his seat on a whale-watching boat, the waters of Monterey Bay in California teemed with activity. A group of California sea lions had just come up for air after feeding on a school of anchovies, and following close behind them was the main
Scientists have just discovered something new about gold. When extreme crushing pressure is applied quickly, over mere nanoseconds, the element’s atomic structure changes, becoming more similar to metals harder than gold. It’s the first time this structural state has ever been observed in gold, suggesting properties that could help scientists refine their understanding of how
Dozens of tourists were injured after a massive wave came crashing down on them in a “tsunami pool” in northeast China, according to Chinese media outlets. City officials from Longjing announced that 44 tourists were injured in the unexpected swell, and that the pool is closed for investigation, the South China Morning Post reported. A
Back in 1976, the late Carl Sagan sat down on the Tonight Show with Johnny Carson to talk about a new form of space propulsion called solar sailing. Four decades later, and The Planetary Society has officially demonstrated this “tremendously exciting prospect” in practice. Drawing on ten years of hard work and 7 million dollars
ATLANTA — NASA Administrator Jim Bridenstine says he believes the agency’s new strategy for increasing commercial use of the International Space Station will lead to an “industrialization” of low Earth orbit, although experts warn it may take time for those markets to emerge. In a July 31 speech at the ISS Research and Development Conference
Misaligned teeth can put you at risk for tooth decay, gum disease, and even tooth loss. Braces shift teeth by applying pressure, which constricts blood flow to the surrounding tissue that holds those teeth in place. That in turn causes special immune cells called osteoclasts to rush in and dissolve part of the jawbone, creating
The Parker Solar Probe will be the first-ever mission to “touch” the Sun, traveling directly into the Sun’s atmosphere about 4 million miles from the surface. Read the story: https://go.nasa.gov/2KEExYZ NASA launch schedule: https://go.nasa.gov/2JfklMB The Sun contains 99.8 of the mass in our solar system. Its gravitational pull is what keeps everything here, from tiny

Just 31 light-years away, one of the closest worlds ever detected could harbour liquid water on its surface. NASA’s Transiting Exoplanet Survey Satellite, or TESS – a super-powerful orbiting telescope that scouts the sky for alien worlds – spotted a new planet circling a nearby star in the Hydra constellation. When astronomers checked the star
Harrison: Space Defense Force “more accurately emphasizes the primary job of military space forces, which is to defend our assets in space.” WASHINGTON — As Congress prepares to write legislation that would authorize the Defense Department to stand up a space service, lawmakers have lots of decisions to make, including the name of the organization.
