An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station—and how this differs from intended uses.
Optical navigation tech could streamline planetary exploration
Write a comment
In a dim, barren landscape like the surface of the moon, it can be easy to get lost. With few discernable landmarks to navigate with the naked eye, astronauts and rovers must rely on other means to plot a course.
As NASA pursues its moon to Mars missions, encompassing exploration of the lunar surface and the first steps on the Red Planet, finding novel and efficient ways of navigating these new terrains will be essential. That's where optical navigation comes in—a technology that helps map out new areas using sensor data.
NASA's Goddard Space Flight Center in Greenbelt, Maryland, is a leading developer of optical navigation technology. For example, GIANT (the Goddard Image Analysis and Navigation Tool) helped guide the OSIRIS-REx mission to a safe sample collection at asteroid Bennu by generating 3D maps of the surface and calculating precise distances to targets.
Now, three research teams at Goddard are pushing optical navigation technology even further.
NASA weighs SpaceX rescue for stranded Boeing Starliner crew
Write a comment
What was meant to be a weeklong trip to the International Space Station (ISS) for the first NASA astronauts to fly with Boeing could extend to eight months, with the agency considering bringing them home on a SpaceX spaceship.
A final decision on whether to persist with Boeing's troubled Starliner—which experienced worrying propulsion issues as it flew up to the orbital platform in June—is expected later this month, officials said Wednesday in a call with reporters.
Detailed planning is already underway with Boeing's rival SpaceX, owned by Elon Musk, to potentially launch their scheduled Crew-9 mission on September 24 with just two astronauts rather than the usual four.
NASA says chances are growing that astronauts may switch from Boeing to a SpaceX ride back to Earth

What should have been a quick trip to the International Space Station may turn into an eight-month stay for two NASA astronauts if they have to switch from Boeing to SpaceX for a ride home.

Detecting nitrogen dioxide emissions from power plants using Sentinel-2 satellites
Write a comment
Atmospheric nitrogen dioxide (NO2) is a hazardous pollutant with profound effects on air quality, climate, and the biosphere. While satellites have been mapping NO2 concentrations since the 1990s, their resolutions have generally been too coarse to identify individual sources such as power plants.
A recent study has made significant strides in air pollution monitoring by using imagery from Seawater barium removal enhanced marine habitability for Cambrian animals
Write a comment
This study, led by Dr. Wei Wei, PhD student Lin-Hui Dong, and Prof. Fang Huang at the University of Science and Technology of China, investigates the removal of excess barium and sulfide from seawater and its impact on marine habitability during the Cambrian Explosion.
Lin-Hui Dong analyzed excess barium contents (Baexcess) and isotope compositions (d138Baexcess) at the State Key Laborator
