The blue hue of the Advanced Electric Propulsion System (AEPS) is seen inside a vacuum chamber at NASA’s Glenn Research Center in Cleveland during recent thruster qualification testing. This 12-kilowatt Hall thruster is the most powerful electric propulsion thruster in production, and it will be critical to future science and exploration missions at the Moon and beyond.

The blue plume is a steady stream of ionized xenon gas ejected to produce low, highly efficient thrust. These electric propulsion systems accelerate spacecraft to extremely high speeds over time using only a fraction of the fuel chemical propulsion systems require, making electric propulsion an excellent choice for deep-space exploration and science missions.

Three AEPS thrusters will be mounted on the Power and Propulsion Element, a foundational component of Gateway. The small lunar space station is critical to the agency’s Artemis missions that will help prepare for human missions to Mars. The Power and Propulsion Element will provide Gateway with power, high-rate communications, and allow it to maintain its unique orbit around the Moon.

Immigration and living on Mars have long been depicted in science fiction works. But before dream turns into reality, there is a hurdle man has to overcome — the lack of essential chemicals such as oxygen for long-term survival on the planet. However, hope looms up thanks to recent discovery of water activity on Mars. Scientists are now exploring the possibility of decomposing water to produce oxygen through electrochemical water oxidation driven by solar power with the help of oxygen evolution reaction (OER) catalysts. The challenge is to find a way to synthesize these catalysts in situ using materials on Mars, instead of transporting them from the Earth, which is of high cost.

To tackle this problem, a team led by Prof. LUO Yi, Prof. JIANG Jun, and Prof. SHANG Weiwei from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), recently made it possible to synthesize and optimize OER catalysts automatically from Martian meteorites with their robotic artificial intelligence (AI)-chemist.

From the very beginning, warp drive has been a major part of Paramount’s Star Trek franchise for the simple reason that it explains how our characters can traverse the galaxy faster than the speed of light. Warp drive has changed a lot over the years, so we decided to see which ship would get from Earth to Jupiter quicker: the Enterprise NX-01 captained by Jonathan Archer, the Enterprise NCC-1701 captained by James T. Kirk, or the Enterprise 1701-D captained by Jean-Luc Picard. The answer is simple: Picard’s ship is the clear winner.

“JWST is revolutionizing exoplanet characterization, providing unprecedented insights at remarkable speed,” said Dr. Leen Decin.

NASA’s James Webb Space Telescope, the world’s most powerful telescope ever built, continues to dazzle with its scientific findings both within and outside our solar system. Most recently, an international team of researchers used JWST’s Mid-Infrared Instrument (MIRI) to analyze the atmosphere of WASP-107b, a Neptune-like exoplanet located approximately 211 light-years from Earth and orbits its parent star in just 5.7 days.

Using MIRI, the team identified water vapor, sulfur dioxide, and silicate sand clouds swirling around in the atmosphere of WASP-107b, which is considered a “fluffy” exoplanet since its mass is close to Neptune’s, but its overall size is closer to Jupiter, making it unique compared to the gas giants of our solar system. The findings were published today in the journal Nature.

Hopefully without a “rapid unscheduled disassembly” this time.

Back in the 1950s, when the larger humanity was just beginning to ponder trips beyond the boundary of our world by means of rockets, visionaries were already dreaming of trips to the Moon and the neighboring planets, some of them so large in scope they were akin to the first colonization moves.

The government plans to establish a new ¥1 trillion ($6.6 billion) fund in a bid to develop the country’s outer space industry, as starry-eyed officials push to enhance Japan’s capabilities.

The ¥1 trillion fund will be allocated over a 10-year period for the Japan Aerospace Exploration Agency (JAXA), an Education, Culture, Sports, Science and Technology Ministry spokesperson said. Some ¥300 billion has been set aside for the fund in the latest supplementary budget approved by the Cabinet on Friday.

“We believe it is a necessary fund to speed up our country’s space development so we don’t lag behind the increasingly intensifying international competition,” Sanae Takaichi, minister in charge of space development, said in a news conference last week.

Elon Musk’s SpaceX is known for its frequent launches, which now dominate the space industry. But the satellites that the rockets send to space are just as important for the company as the launches. Starlink is SpaceX’s answer to providing global, high-speed internet coverage using a network of thousands of satellites buzzing around the planet in a region known as low Earth orbit (LEO), about 342 miles above the Earth’s surface.

SpaceX launched its first batch of Starlink satellites in 2019. Adoption of the service has ballooned since then. The company has said Starlink has more than 2 million active customers and is available on all seven continents and in over 60 countries.

“This growth is uncharacteristic in the sense of its magnitude. Whereas prior satellite service providers have ramped up to anywhere at most between 500,000 to a little bit over a million subscribers. And this has taken, you know, a ten-year period, Starlink’s race to 2 million subscribers has taken only the better part of two years,” says Brent Prokosh, a Senior Affiliate Consultant at Euroconsult.
