CGTN:Tianhe lifts off China's space station ambition – Canada NewsWire

Published

 on


Tianhe will act as the foundational module for China’s first space station in low-Earth orbit named Tiangong, which means “heavenly palace” in Chinese.

Chinese President Xi Jinping said in a congratulatory message Thursday that the successful launch of the core module Tianhe means that China’s space station construction has entered the full implementation stage, which lays a solid foundation for follow-up tasks.

Building a space station and national space laboratory is an important goal of the three-step strategy of China’s manned space program, and an important leading project to boost the country’s strength in science and technology, as well as in space, Xi said in the message.

He called on all members who participated in the mission to be self-reliant and innovative, to win the overall victory of the space station construction mission, and to make new and greater contributions to the comprehensive construction of a modern socialist country.

An open platform

China’s new space station will not just be for Chinese scientists. Foreign astronauts and global cooperation on scientific experiments are most welcome in China’s space station, Hao Chun, the director of China Manned Space Engineering Office, said in an exclusive interview with CGTN.

China and the United Nations Office for Outer Space Affairs carried out cooperation on applications concerning the use of China’s space station. We signed an agreement,” said Hao.

So far, a total of nine projects proposed by 17 countries including France, Germany and Italy have been selected for the first round of experiments to be conducted in the new space lab.

“In the future, there will surely be foreign astronauts participating in China’s space flight, working and living on our space station. In addition, some foreign astronauts are already participating in Chinese flights and are already learning Chinese,” said the director.

Build an aerospace power

Since the 18th National Congress of the Communist Party of China (CPC), Xi, also general secretary of the CPC Central Committee, has personally directed the implementation of major aerospace projects, and promoted China’s steady progress to become an aerospace power.

“Exploring the vast universe, developing space programs and becoming an aerospace power have always been the dream we’ve been striving for,” Xi said in an instruction on China’s first Space Day on April 24, 2016.

In 2020, China’s space industry has produced remarkable achievements: China successfully put into orbit its final Beidou satellite on June 23; an unmanned probe to Mars was sent into space on July 23; an uncrewed mission called Chang’e-5 with the aim of collecting lunar material was launched on November 24 and China successfully landed the Chang’e-5 probe on the moon’s surface on December 1.

A HOLE in the Milky Way Galaxy found; may reveal how stars are formed – HT Tech

Published

 on


In another step taking humans closer to understanding the origins of the universe and how stars are formed, astronomers have discovered a massive void in the Milky Way Galaxy, between star-forming regions in the Perseus and Taurus constellations, according to a new study. The void, or space cavity, is a massive 500 light-years in width.

According to several reports, the void in the Milky Way Galaxy was spotted surrounded by molecular clouds, which could have been formed by the explosive death of a star around 10 million years ago, also known as a supernova. The researchers at the Institute for Theory and Computation (ITC) at the Harvard-Smithsonian Center For Astrophysics (CfA) believe the study’s findings could help scientists understand how stars could be formed due to supernovas.

In a statement, the researchers stated that the European Space Agency’s star-mapping Gaia spacecraft yielded data that was used to map molecular clouds located around the void, giving them a 3D view for the first time, a big upgrade over two-dimensional views of the Milky Way Galaxy region. The researchers say that they now know where they lie “with only 1 percent uncertainty” which will allow them to calculate the distance of the void from Earth.

In order to visualise the data, the researchers used software called Glue, which allowed them to create 3D molecular maps that could map the region where stars are formed. This new perspective will help them study how molecular clouds can be formed with gas and dust after a supernova explosion – to form new stars. “You can literally make the universe float over your kitchen table,” says Harvard professor and CfA astronomer Alyssa Goodman.

The data from these 3D maps of the region showed the researchers that the previously mentioned clouds were not actually connected, but instead located on either side of a large, invisible cavity. The clouds could have been formed as a result of the same supernova explosion about 10 million or 20 million years ago, according to the researchers. The findings of the study were published on September 22 in The Astrophysical Journal.

Elon Musk Confirms "Challenges" With Toilet on Tourist Spacecraft – Futurism

Published

 on


“Definitely upgraded toilets” for the next flight.

What’s That Smell?

As if going to the bathroom in microgravity wasn’t complicated enough.

It sounds as though the four space tourists on SpaceX’s historic Inspiration4 flight last week had a bit of a smelly mishap. The Waste Management System experienced an “anomaly” — that’s code of “uh oh” in space jargon — with its suction fan causing the crew to struggle with doing their business while floating hundreds of miles above the surface.

Musk also promised a number of improvements for the next all-civilian space tourism flight. “Definitely upgraded toilets,” Musk responded to another Twitter account suggesting heated toilet seats. “We had some challenges with it this flight.”

We still don’t know how the faulty suction fan ended up affecting the crew’s three day trip. But if the history of crewed spaceflight is anything to go by, there’s a chance things got pretty unpleasant. Three days is also a long time to be stuck without any fresh air.

Space toilet technologies are still very much a work in progress, despite the many decades of human spaceflight. Last year, NASA launched a call for better space toilet designs that could gift future astronauts a better bathroom experience.

“If you ever pooped in space, you know that they need help,” Christian Cotichini, the CEO HeroX, which collaborated with NASA on the initiative, told Futurism last year. “I’ve got some video I can send you. It’s not pretty.”

The toilet on board the International Space Station has also experienced its fair share of failures, at one point causing gallons of “water” to flood into the cabin in 2019.

A trip on board a Crew Dragon will unquestionably be an expensive affair. It’s only fair that SpaceX uses last week’s launch as a learning experience to make some improvements.

Oldest evidence of human presence in Americas discovered in new research – The Jerusalem Post

Published

 on


A team of archaeologists found that humans lived in North America during the Last Glacial Maximum, between 21,000 and 23,000 years ago, in a peer-reviewed study published by Science.org on Friday.
A US Geological Survey team led by Jeff Pigati and Kathleen Springer analyzed seed layers surrounding human footprints at Lake Otero in White Sands National Park, New Mexico, and found that they coincided with a major warming event that caused lower water levels, exposing ground on which humans and prehistoric animals walked.
The findings also suggest the coexistence of humans and prehistoric animals at a point in time where the phenomenon was previously unknown to have occurred. In addition to the human footprints, tracks were left by giant ground sloths, dire wolves, mammoths, and birds.

“It is an important site because all of the trackways we’ve found there show an interaction of humans in the landscape alongside extinct animals, like mammoths and giant sloths,” said Sally Reynolds of Bournemouth University, who co-authored the study.
“We can see the co-existence between humans and animals on the site as a whole, and by being able to accurately date these footprints, we’re building a greater picture of the landscape,” she added.

The human footprints are the oldest evidence of human presence in the Americas, according to the University of Arizona. Previously, the only reliable evidence available suggested humans arrived in the region no more than 13,000-16,000 years ago. Based on the size of the footprints, the researchers ascertained that most of them were left by teenagers and children, though a few belonged to adults.
“We can think of our ancestors as quite functional, hunting and surviving, but what we see here is also activity of play, and of different ages coming together. A true insight into these early people,” said Matthew Bennett of Bournemouth University, another co-author of the study.
