New automatic control technique uses spacecraft solar panels to reach desired orbit at Mars
A satellite on a science mission to Mars aims for a low-altitude orbit, but the lower the orbit, the more propellant is required to enter orbit when arriving from Earth. To save propellant, a technique called aerobraking uses a small propulsive maneu.....»»
Pushing the limits of sub-kilowatt electric propulsion technology for space mission concepts
NASA has developed an advanced propulsion technology to facilitate future planetary exploration missions using small spacecraft. Not only will this technology enable new types of planetary science missions, one of NASA's commercial partners is alread.....»»

A NASA rover has reached a promising place to search for fossilized life on Mars
While we go about our daily lives on Earth, a nuclear-powered robot the size of a small car is trundling around Mars looking for fossils. Unlike its predecessor Curiosity, NASA's Perseverance rover is explicitly intended to "search for potential evid.....»»
A shade closer to more efficient organic photovoltaics
Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitra.....»»
Imaging technique shows new details of peptide structures
A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with Alzheimer's disease......»»

Light-activated materials perform well in treatment of textile effluent
Photoelectrochemical processes have been considered sustainable alternatives for the remediation of water contaminated by domestic or industrial effluents. Simply put, the strategy consists of using solar energy to degrade organic pollutants......»»
NASA to overhaul mission returning samples from Mars—here"s why it must and will go ahead
NASA recently announced that it is seeking new ways to complete the return to Earth of rock cores drilled by the Perseverance Rover in the Jezero Crater on Mars. This has led to some anxiety among space scientists, who view the Mars Sample Return (MS.....»»
Astronauts take major step toward Starliner’s first crewed flight
After numerous delays across many years, NASA is closer than ever to launching its first astronauts aboard the Boeing-made CST-100 Starliner spacecraft......»»
Voyager 1 spacecraft is still alive and sending signals to Earth
NASA has announced that it is back in contact with Voyager 1, around five months after communications with the spacecraft were disrupted......»»
Magnetic with a pinch of hydrogen: Research team develops new idea to improve the properties of ultra-thin materials
Magnetic two-dimensional materials consisting of one or a few atomic layers have only recently become known and promise interesting applications, for example for the electronics of the future. So far, however, it has not been possible to control the.....»»
