The U.S. Space Command chief met with the head of South Korea's military in Seoul after the two countries agreed to strengthen space cooperation at the White House Friday.
Gen. James Dickinson met with South Korean Defense Minister Suh Wook to discuss partnerships in space from a defense perspective, Yonhap reported Monday.
The two sides indicated "continued efforts" are needed to maintai Enabling human control of autonomous partners

A major benefit of increasingly advanced automation and artificial intelligence technology is decreased workload and greater safety for humans - whether it's driving a vehicle, piloting an airplane, or patrolling a dangerous street in a deployed location with the aid of autonomous ground and airborne squad mates. But when there's a technology glitch and machines don't function as designed, human NASA Marshall team soars to success in microgravity

No force - including gravity - could hold a team of NASA researchers down in their quest for a scientific breakthrough to benefit life on Earth and in space.
Scientists from NASA's Marshall Space Flight Center in Huntsville, Alabama, completed two parabolic flights April 28 and 29 to test modifications to a payload called the ring-sheared drop.

China launched its latest oceanographic research satellite, HY-2D, on a Long March 4B carrier rocket from the Jiuquan Satellite Launch Center in the Gobi Desert on Wednesday morning, the China National Space Administration said.
It said in a statement that the satellite will be tasked with working with its two predecessors-HY-2B and HY-2C-to form a space-based network monitoring the marine NASA tests system for aircraft positioning in supersonic flight

Pacific sees a 'Blood Moon' rising
Write a comment
Stargazers across the Pacific Rim will cast their eyes skyward on Wednesday night to witness a rare "Super Blood Moon", as the heavens align to bring an extra-spectacular lunar eclipse.
The first total lunar eclipse in two years will happen at the same time as the Moon is closest to Earth, in what astronomers say will be a once-in-a-decade show.
If the skies are clear, anyone living in the Pacific between Australia and the central United States will be able to see an enormous, bright, orangey-red Moon.
The main event will be between 1111-1125 GMT—late evening in Sydney and pre-dawn in Los Angeles—when the Moon will be entirely in the Earth's shadow.
The Moon will darken and turn red—a result of sunlight refracting off the Earth's rim onto the lunar surface—basking our satellite in a sunrise- or sunset-tinged glow.
PUNCH mission passes important milestone

On May 20, 2021, the Polarimeter to UNify the Corona and Heliosphere (PUNCH) mission achieved an important milestone, passing NASA's Preliminary Design Review (PDR) of its spacecraft and payload experiments.
Why the sun's atmosphere is hundreds of times hotter than its surface
Write a comment
The visible surface of the sun, or the photosphere, is around 6,000°C. But a few thousand kilometers above it—a small distance when we consider the size of the sun—the solar atmosphere, also called the corona, is hundreds of times hotter, reaching a million degrees celsius or higher.
This spike in temperature, despite the increased distance from the sun's main energy source, has been observed in most stars, and represents a fundamental puzzle that astrophysicists have mulled over for decades.
In 1942, the Swedish scientist Hannes Alfvén proposed an explanation. He theorized that magnetized waves of plasma could carry huge amounts of energy along the sun's magnetic field from its interior to the corona, bypassing the photosphere before exploding with heat in the sun's upper atmosphere.
The theory had been tentatively accepted—but we still needed proof, in the form of empirical observation, that these waves existed. Our recent study has finally achieved this, validating Alfvén's 80 year-old theory and taking us a step closer to harnessing this high-energy phenomenon here on Earth.
