Carbon dioxide glaciers are moving at the Martian south pole
Wednesday, 27 April 2022 06:42
Glaciers of carbon dioxide are moving, creating deposits kilometers thick today across the south polar region of Mars, something that could have been going on more than 600,000 years, a paper by Planetary Science Institute Research Scientist Isaac Smith says.
"The CO2 deposits that were first identified in 2011 turn out to be flowing today, just like glaciers on Earth," said Smith, lead au Scientists find DNA's code for life in meteorites
Wednesday, 27 April 2022 06:42
New evidence found in meteorites suggests the ingredients for life came from space.
Scientists at NASA and in Japan confirmed Tuesday they found all five key building blocks of DNA and RNA in space rocks that fell to Earth within the last 100 years, according to research published in the journal Nature Communications.

China continues to display a lack of transparency and willingness to cooperate with the United States and other countries in space, NASA Administrator Bill Nelson said on Tuesday.
"We want cooperation that has not been forthcoming from the Chinese government (but) it takes two to tango," Nelson told a press conference at the Kennedy Space Center in Florida. "We simply haven't had any trans NASA selects investigation teams to join Geospace Dynamics Mission

China plans system to take out asteroids hurtling toward Earth
Tuesday, 26 April 2022 14:46
China plans to develop a system for monitoring asteroids that pose a threat to earth, highlighting the nation's growing ambitions for its space program.
The country will also explore ways for taking out asteroids that endanger the planet, Wu Yanhua, deputy director of the China National Space Administration, said in a TV interview, according to the official Xinhua News Agency.
To test the system, China intends to send a spacecraft toward an asteroid in 2025 or 2026 to study it and then change its course, Wu added, without providing details on how that would work.
The Asian nation has pushed forward with plans for its space program in recent years. In January, Wu said Beijing signed an agreement with Russia to build a base on the moon, and last year a Chinese moon mission returned to earth with lunar samples.
China's aspirations for its space program have ramped up tensions with the U.S. The two sides have sparred over SpaceX satellites that Beijing said came dangerously close to its space station, prompting the government of the Asian nation to criticize SpaceX in a memo to a United Nations committee that oversees operations in space.
NASA gives green light for OSIRIS-REx spacecraft to visit another asteroid
Tuesday, 26 April 2022 14:30
NASA's OSIRIS-REx spacecraft will swing by Earth to deliver a sample from asteroid Bennu on Sept. 24, 2023. But it won't clock out after that.
NASA has extended the University of Arizona-led mission, which will be renamed OSIRIS-APEX, to study near-Earth asteroid Apophis for 18 months. Apophis will make a close approach to Earth in 2029.
The University of Arizona will lead the mission, which will make its first maneuver toward Apophis 30 days after the OSIRIS-REx spacecraft delivers the sample it collected from Bennu back in October 2020. At that point, the original mission team will split—the sample analysis team will analyze the Bennu sample, while the spacecraft and instrument team transitions to OSIRIS-APEX, which is short for OSIRIS-Apophis Explorer.
