NASA AI technology could speed up fault diagnosis process in spacecraft

New artificial intelligence technology could speed up physical fault diagnosis in spacecraft and spaceflight systems, improving mission efficiency by reducing down-time.
Research in artificial intelligence for spacecraft resilience (RAISR) is software developed by Pathways intern Evana Gizzi, who works at NASA's Goddard Space Flight Center in Greenbelt, Maryland. With RAISR, artificial intelligence could diagnose faults real-time in spacecraft and spaceflight systems in general.
"The spacecraft reporting a fault is like a car with a check engine light on," Gizzi said. "You know there is an issue, but can't necessarily explain the cause. That's where the RAISR algorithm comes in, diagnosing the cause as a loose gas cap."
Right now, the ability to make inferences about what is happening that go beyond traditional 'if-then-else' fault trees is something only humans can do, Gizzi said.
Moonlight: bringing connectivity to the Moon

As international teams across the world forge plans to revisit the Moon, ESA is elaborating how best to facilitate this exploration.
As part of its Moonlight initiative, the agency is encouraging European space companies to put a constellation of telecommunications and navigation satellites around the Moon.
To succeed, the proposed lunar missions will require reliable navigation and telecommunication capabilities. Building these independently would be costly, complex and inefficient.
If this work were outsourced to a consortium of space companies, each individual mission would become more cost-efficient.

Moon mission delays could increase risks from solar storms
Thursday, 20 May 2021 06:36 Write a comment
Planned missions to return humans to the Moon need to hurry up to avoid hitting one of the busiest periods for extreme space weather, according to scientists conducting the most in-depth ever look at solar storm timing.
Scientists at the University of Reading studied 150 years of space weather data to investigate patterns in the timing of the most extreme events, which can be extremely dangerous to astronauts and satellites, and even disrupt power grids if they arrive at Earth.
The researchers found for the first time that extreme space weather events are more likely to occur early in even-numbered solar cycles, and late in odd-numbered cycles—such as the one just starting. They are also more likely during busy periods of solar activity and in bigger cycles, mirroring the pattern for moderate space weather.
The findings could have implications for the NASA-led Artemis mission, which plans to return humans to the moon in 2024, but which could be delayed to the late 2020s.
Professor Mathew Owens, a space physicist at the University of Reading, said: "Until now, the most extreme space-weather events were thought to be random in their timing and thus little could be done to plan around them.

Scientists have long thought that there was a direct connection between the rise in atmospheric oxygen, which started with the Great Oxygenation Event 2.5 billion years ago, and the rise of large, complex multicellular organisms.
That theory, the "Oxygen Control Hypothesis," suggests that the size of these early multicellular organisms was limited by the depth to which oxygen could diffuse Nelson uses Chinese Mars landing as a warning to Congress

WASHINGTON — NASA Administrator Bill Nelson congratulated China for successfully landing a rover on Mars, but also used the milestone to warn Congress of China’s competitive threat to American leadership in human spaceflight.
In a statement May 19, hours after the China National Space Administration (CNSA) released the first images taken by the Zhurong rover since its May 14 landing on Mars, Nelson congratulated China for being only the second country, after the United States, to land a spacecraft on Mars and operate it there for more than a brief period.

The launch of China's Tianzhou 2 robotic cargo spacecraft that was originally scheduled for early Thursday morning has been postponed due to technical issues, according to the China Manned Space Agency.
The agency said in a brief statement shortly before the preplanned launch time that the new launch time will be determined in due course.
It didn't give more details.
