Dream Home on Red planet? Scientists Develop Cosmic Concrete to Build House on Mars

  Researchers have developed a material like concrete that combines extraterrestrial dust and astronauts' sweat, blood, and tears. It is very expensive to transport even a single brick to Mars. An estimated US$2 million is required.In the future, Martian colonists will not be able to bring their building materials with them, but they will be able to obtain resources on-site for construction and shelter.  A protein found in blood plasma plays a crucial role as a binder for simulated dust from the moon, Mars, or both, and can produce emulsions similar to concrete, according to a study conducted at the University of Manchester.

According to the article published in Materials Today Bio, the resulting AstroCrete material had compressive strengths of 25 MPa (Megapascals), similar to the 20-32 MPa seen in ordinary concrete.


By incorporating urea, which is a biologically excreted waste product, the best performing material was capable of increasing its compressive strength by nearly 300 percent, with the best performing material having a compressive strength of over 40 MPa, substantially stronger than ordinary concrete.

Aled Roberts, from the varsity, who was involved in the project, said the new technology offers many advantages compared to some of the other proposed methods for building on the moon and Mars.


“Scientists have been trying to develop viable technologies to produce concrete-like materials on the surface of Mars, but we never stopped to think that the answer might be inside us all along," he said.


The team calculated that over 500 kg of high-strength AstroCrete could be produced throughout a two-year mission on the surface of Mars by a crew of six astronauts.

The astronauts could produce enough AstroCrete to double the space for more crew members with each successive mission if it was used as a mortar for sandbags or heat-fused regolith bricks.

Earth's shine seems to be fading due to global warming as the oceans heat up

  In recent years, the climate change crisis has escalated to unprecedented levels, resulting in unimaginable and life-changing consequences. An acclaimed new study contends that global warming is dimming our planet, literally! Global warming is causing the Earth's brightness to decrease, according to a new study. Now you're probably wondering, "how do you even measure something like that?" But researchers have their ways. Keeping track of the Earth's shine requires them to calculate the Earth's 'albedo', or reflectance. The albedo is calculated utilizing something called the 'earthshine'. The crescent moon is most noticeable immediately after sunset or before sunrise, when its dazzling crescent gives way to a dark disc with a faint glow. A crescent moon's unlit parts are known as earthshine because they are glowing from the light reflected from the Earth. The study revealed that earthshine data over the last three years indicates that our ...

What is Gun Cotton? How is it different from Black Gun Powder?

  Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin, and flash string, depending on form) is a highly flammable compound formed by nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as a propellant in firearms. Guncotton was actually developed as a “Smokeless Gun Powder”, Essentially, the main difference between Black Gun Powder and Smokeless Gun Powder is that you need almost zero incombustible components. The key problem with black powder was that it produced a cloud of smoke, not only from Un combusted carbon but also, unavoidably, from ash, the salts formed from whatever anion happened to latch on to the sodium or potassium cations present from the nitrates in black powders. Black powder ash contains a high proportion of potassium or sodium sulfates and carbonates, and because the inorganic saltpeter component was about 2/3 of...
