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.

A plan to use a Russian spacecraft to deorbit the International Space Station as early as 2028 remains in question because the United States does not know Russia's intentions for using the orbiting laboratory, NASA and other parties involved in the decision say.
A NASA safety panel approved a plan in 2019 that relies on Russia to modify and launch a Progress spacecraft to guide the stru Size of supermassive black hole divulged by eating pattern
Friday, 13 August 2021 07:52 Write a comment
Astronomers have finally linked the size of a supermassive black hole to the spectral patterns generated by its eating habits.
Most nearby supermassive black holes are dormant. These long-sated, sleeping giants ate up their supply of gas and dust many millions of years ago, leaving them dark and quiet.
To identify dormant black holes, scientists must measure their gravitational i Army successfully tests high-energy laser weapon
Friday, 13 August 2021 07:52 Write a comment
The U.S. Army says it's developed a combat-capable prototype of a high-energy laser weapon.
The laser, which has been 24 months in the making, can be mounted on a Stryker military vehicle and used to defend troops against drones as well as rockets, artillery and mortars, according to an Army press release this week.
Over the summer, the new weapon was successfully tested in Fort Exponential growth of cubesats may be tapering off
