Like many other industries, the space exploration process is also adopting Artificial Intelligence (AI) and robotics to fast-track its mission. This leads us to great lengths and never explored places. Emerging technologies like machine learning and deep learning are organizations working in space programs an opportunity to embrace AI and robotics. Robots help the space exploration process through the mechanical design of planetary rovers, the mechanical design of space manipulators, actuators and sensors of space robots, end-effector/tools of space robots, reconfigurable robots, and robot mobility. Here are some exemplary cases of robotics and AI in space tech.

1. Canadian Space Association launched Dextre, a robotic arm designed to install and replace small equipment such as exterior cameras or the 100-kg batteries used on the Space Station, and to test new tools and robotics techniques.

2. Voyager 1 and Voyager 2, were designed to conduct close-up studies of Jupiter and Saturn, Saturn’s rings, and both Jupiter and Saturn’s largest moon. These robots are still communicating information via the Deep Space Network (DSN) and are presently closer to Pluto than to Earth or the sun.

So Excited!!…We Are All Invited!!…❤️🕶❤️…

NASA, in partnership with ESA (European Space Agency) and CSA (Canadian Space Agency), will release the James Webb Space Telescope’s first full-color images and spectroscopic data during a televised broadcast beginning at 10:30 a.m. EDT on Tuesday, July 12, from NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Ten years ago today, China sent a crew to its thus-far unoccupied Tiangong-1 space station. When the crew arrived two days later, the nation joined Russia and the United States in a rarified spacefaring club that marked the beginning of China’s space ascent.

On June 16, 2012, the China Manned Space Agency launched the Shenzhou-9 mission. Its three-person crew — commander Jing Haipeng, major Liu Wang, and China’s first woman in space, major Liu Yang — flew into Earth orbit atop a Long March rocket from Jiuquan Satellite Launch Center near Mongolia in the Gobi Desert. They successfully docked with China’s Tiangong-1 space lab on June 18.

It was a long time coming. In 2008, China successfully docked its Shenzhou 8 craft to the Tiangong-1 space station. But both the space station and its new addition were uncrewed, guided on the ground by mission control. That left it up to the Shenzhou 9 crew to make history by taking it literally into their own hands. Taikonaut Liu Wang piloted Shenzhou 9 toward Tiangong-1, easing into position for a soft docking. After securing various bolts and locks, ground control began equalizing the air pressure between the capsule and station. Three hours later, the crew entered the station.

Though the planets are outside of their star’s habitable zone, as they orbit too closely, “there might be more planets in the system,” according to Avi Shporer, one of the scientists involved in the new study. “There are many multiplanet systems hosting five or six planets, especially around small stars like this one. Hopefully, we will find more, and one might be in the habitable zone. That’s optimistic thinking.”

Either way, the multiplanet system will likely be a focal point for future studies, shedding new insight into planetary formation and the evolution of alien worlds, helping the astronomical community better understand how our own planet came into existence.

Hong Kong, a densely populated city where agriculture space is limited, is almost totally dependent on the outside world for its food supply. More than 90% of the skyscraper-studded city’s food, especially fresh produce like vegetables, is imported, mostly from mainland China. “During the pandemic, we all noticed that the productivity of locally grown vegetables is very low,” says Gordon Tam, cofounder and CEO of vertical farming company Farm66 in Hong Kong. “The social impact was huge.”

Tam estimates that only about 1.5% of vegetables in the city are locally produced. But he believes vertical farms like Farm66, with the help of modern technologies, such as IoT sensors, LED lights and robots, can bolster Hong Kong’s local food production—and export its know-how to other cities. “Vertical farming is a good solution because vegetables can be planted in cities,” says Tam in an interview at the company’s vertical farm in an industrial estate. “We can grow vegetables ourselves so that we don’t have to rely on imports.”

Tam says he started Farm66 in 2013 with his cofounder Billy Lam, who is COO of the company, as a high-tech vertical farming pioneer in Hong Kong. “Our company was the first to use energy-saving LED lighting and wavelength technologies in a farm,” he says. “We found out that different colors on the light spectrum help plants grow in different ways. This was our technological breakthrough.” For example, red LED light will make the stems grow faster, while blue LED light encourages plants to grow larger leaves.

The ancestors of some of the largest galaxy clusters have been hiding in plain sight. New work led by Carnegie’s Andrew Newman demonstrates a new technique for identifying the precursors of the most extreme galactic environments. The team’s findings are published in Nature.

Like all of us, are shaped and molded by their surroundings. To obtain a complete picture of the various physical influences on a galaxy’s lifecycle, it’s crucial to trace the emergence of properties caused by as they arise.

“We’ve known for a long time that the colors, masses, and shapes of galaxies depend on their cosmic environment, but there’s a lot we don’t know about when and how those differences appeared,” Newman said.

Astronomers are buzzing after observing the fastest nova ever recorded. The unusual event drew scientists’ attention to an even more unusual star. As they study it, they may find answers to not only the nova’s many baffling traits, but to larger questions about the chemistry of our solar system, the death of stars and the evolution of the universe.

The research team, led by Arizona State University Regents Professor Sumner Starrfield, Professor Charles Woodward from University of Minnesota and Research Scientist Mark Wagner from The Ohio State University, co-authored a report published today in the Research Notes of the American Astronomical Society.

A is a sudden explosion of bright light from a two-star system. Every nova is created by a white dwarf—the very dense leftover core of a star—and a nearby companion star. Over time, the white dwarf draws matter from its companion, which falls onto the white dwarf. The white dwarf heats this material, causing an uncontrolled reaction that releases a burst of energy. The explosion shoots the matter away at high speeds, which we observe as .
