Perched atop a stand in the middle of a high-ceilinged clean room, DART is beginning to look like the intrepid spacecraft that will aim itself directly into an asteroid next fall. With the addition of its compact Roll-Out Solar Arrays (ROSA) coiled into two gold cylinders that flank the sides of the spacecraft, and its less visible but still integral imager, the Didymos Reconnaissance and Astero NASA, Boeing to Move Starliner to Production Facility for Propulsion System Evaluation

NASA and Boeing have decided to postpone the launch of Orbital Flight Test-2 to the International Space Station as teams continue work on the CST-100 Starliner propulsion system.
Engineering teams have been working to restore functionality to several valves in the Starliner propulsion system from inside United Launch Alliance's Vertical Integration Facility that did not open as designed du On chaos, drunks and a solution to the chaotic three-body problem

The three-body problem is one of the oldest problems in physics: it concerns the motions of systems of three bodies, like the Sun, Earth and the Moon - how their orbits change and evolve due to their mutual gravity. The three-body problem has been a focus of scientific inquiry ever since Newton.
When one massive object comes close to another, their relative motion follows a trajectory dict Traces of Ceres' icy crust found at Occator Crater

Anomalies in the distribution of hydrogen at Occator crater on the dwarf planet Ceres reveal an icy crust, says a new paper led by Tom Prettyman, a Senior Scientist at the Planetary Science Institute.
The evidence comes from data acquired by the Gamma Ray and Neutron Detector (GRaND) aboard NASA's Dawn spacecraft. A detailed map of the concentration of hydrogen in the vicinity of Occator w Business growth scheme open to next group of space entrepreneurs

Boeing announced Friday that it has to send its troubled CST-100 Starliner capsule to a factory for repairs, delaying an unmanned test flight to the International Space Station (ISS) for several months.
The spacecraft had been due to launch from Cape Canaveral, Florida, on August 3 on an Atlas V rocket built by United Launch Alliance but the flight was delayed because of problems with four p Best of both worlds-combining classical and quantum systems to meet supercomputing demands

Growing crops on Mars? Probably not under the naked sun
Friday, 13 August 2021 15:17 Write a comment
If humans want to live on Mars for a longer period it will be necessary to grow their own crops over there. And what is more logical than growing the crops in a greenhouse on the surface, profiting from the sunlight, as seen in many scientific designs and Sci-fi movies? However, will this be possible giving the high amount of cosmic radiation at the Martian surface level? Wageningen University & Research and the Reactor Institute Delft (RID, TU Delft) have been investigating for some time now the effect of cosmic radiation on Martian surface on plant growth. This revealed that, just like humans, plants also need to be protected from the cosmic radiation.
BSc, student Nyncke Tack investigated the effect of gamma radiation as was recorded by the Mars rover Curiosity on garden cress and rye. "Because the radiation on Mars is much higher than on Earth (230 μGy/d, about 17 times higher than on Earth) the experiment was carried out under strict safety precautions. We conducted the experiment in a special 'led castle' and in a fume hood," says Tack.
