Researchers are developing a predictive model to help NASA anticipate conflicts and communication breakdowns among crew members and head off problems that could make or break the Mission to Mars. Highlights: Space exploration analogs in US, Russia offer rare opportunity to study teams in isolation, confinement; Mars crew will likely experience decline in creative thinking, problem solving; predictive model may allow NASA to foresee, address team problems before they arise.
Queen Mary University of London has led a study which describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading to the heating of interplanetary space.
Measurements of gravitational waves from ~50 binary neutron stars over the next decade will definitively resolve an intense debate over how fast our universe is expanding, find an international team including UCL and Flatiron Institute cosmologists.
The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton, about 2,200 pounds. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. To do that, we need to figure out how to land more mass. That was the goal of a recent study.
A team of researchers repurposed navigational sensors aboard NASA's Curiosity rover, enabling the scientists to measure gravity on the lower slopes of Mount Sharp, a peak that rises from the center of Gale Crater. The results suggest that these rock layers are much less dense than predicted, calling into question a competing theory that Gale Crater was once completely filled with sediment then later excavated by erosion, leaving only Mount Sharp behind.
Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA's Neutron star Interior Composition Explorer (NICER) aboard the International Space Station.
MIT engineers have now developed an algorithm that lets AUVs weigh the risks and potential rewards of exploring an unknown region. For instance, if a vehicle tasked with identifying underwater oil seeps approached a steep, rocky trench, the algorithm could assess the reward level (the probability that an oil seep exists near this trench), and the risk level (the probability of colliding with an obstacle), if it were to take a path through the trench.
On Jan. 4, 2019, at 4:37 a.m. EST the CAPER-2 mission launched from Norway. The rocket flew through active aurora borealis, or northern lights, to study the waves that accelerate electrons into our atmosphere.
Scientists from The Australian National University (ANU) have used new space technology to predict droughts and increased bushfire risk up to five months in advance.
Should regulations for environmental protection be valid beyond our solar system? Currently, extra-terrestrial forms of life are only deemed worth protecting if they can be scientifically investigated. But what about the numerous, presumably lifeless planets whose oxygen atmospheres open up the possibility of their settlement by terrestrial life forms? Theoretical physicist Claudius Gros from Goethe University has taken a closer look at this issue.
