Here’s How To Fix The Big Problems With Elon Musk’s Mars Spaceship

Posted by in categories: Elon Musk, space travel

This week electrovehicle and space transit magnate Elon Musk unveiled his master plan for the human race to become “a multi-planetary species”, starting with travel to Mars. But while I know it’s an act of remarkable hubris for me to even say this, I believe SpaceX’s plans for their Interplanetary Transport System have some pretty glaring flaws. The good news is they are flaws that are easily corrected by applying some decades-old solutions from the American and Soviet space-faring experience.

After going over the system architecture and basic spacecraft design, I think there are places where the system can be made to use less fuel, reduce manufacturing complexity, increase crew room, deliver more payload, and more.

Comparing Reactions of different Groups to Nuclear Thermal Rocket enabled space colonization

Posted by in categories: biotech/medical, habitats, health, space travel

Nextbigfuture wrote about the designs for an improved nuclear thermal rocket by John Bucknell. John has worked as a senior engineer on the SpaceX Raptor rocket. John provides high quality qualified work to his rocket designs and to his proposed space habitat.

Nextbigfuture comments had some technical observations about Project Timberwind and a comment from John himself that his design improves on flaws in the last major nuclear thermal rocket experiments. There were also comments and discussion about Star Trek and communism and O’Neill space stations.

Constructing full earth like conditions in Space with technology proven in the sixties

Posted by in categories: government, habitats, nuclear energy, space travel

John Bucknell presented at the Starship Congress 2017 his Nuclear Thermal Turbo Rocket and applied for a single stage to orbit mission of placing a space habitat. John Bucknell worked on the SpaceX Raptor rocket as a senior engineer so he is very qualified to understand current rocket technology and rockets in general.

Nextbigfuture has noted that NASA has funded $18.8 million on advancing nuclear thermal rocket propulsion by studying low enriched uranium for the fuel. Nuclear-powered rocket concepts are not new. The United States conducted studies and significant ground tests from 1955 to 1972 to determine the viability of such systems, but ceased testing when plans for a crewed Mars mission were deferred.

The NERVA NRX (Nuclear Rocket Experimental) program started testing in September 1964. The final engine in this series was the XE, designed with flight design hardware and fired in a downward position into a low-pressure chamber to simulate a vacuum. SNPO fired NERVA NRX/XE twenty-eight times in March 1968. The series all generated 1100 MW, and many of the tests concluded only when the test-stand ran out of hydrogen propellant. NERVA NRX/XE produced the baseline 75,000 lbf (334 kN) thrust that Marshall required in Mars mission plans.

Project RAMA: Reconstructing Asteroids Into Mechanical Automata

Posted by in categories: solar power, space travel, sustainability

Many interesting ideas have been conceived for building space-based infrastructure in cislunar space. From O’Neill’s space colonies, to solar power satellite farms, and even prospecting retrieved near earth asteroids. In all the scenarios, one thing remained fixed — the need for space resources at the outpost. To satisfy this need, O’Neill suggested an electromagnetic railgun to deliver resources from the lunar surface, while NASA’s Asteroid Redirect Mission called for a solar electric tug to deliver asteroid materials from interplanetary space. At Made In Space, we propose an entirely new concept. One which is scalable, cost effective, and ensures that the abundant material wealth of the inner solar system becomes readily available to humankind in a nearly automated fashion. We propose the RAMA architecture, which turns asteroids into self-contained spacecraft capable of moving themselves back to cislunar space.

Space Exploration Masters

Posted by in categories: business, habitats, robotics/AI, space travel

Space exploration contains large potential for the creation of innovative applications, products and services, also benefitting Earth. With new topics and application areas arise countless possibilities for technology transfer and novel ideas for space-based technologies and their application in non-space industries, as well as new targets and opportunities for business.

This year AZO has launched the Space Exploration Masters on behalf of the European Space Agency (ESA) and in line with the goals of the ESA Space Exploration Strategy, in cooperation with strong world-class partners. The Space Exploration Masters is an international competition to identify best technology transfer business successes, as well as to empower and foster business innovation around space exploration activities in Low Earth Orbit (LEO), on Moon, Mars, or beyond – for the benefit of society and Earth.

The two different prize categories “Technology Transfer Success “ and “New Business Innovation “ look for exciting submissions in the fields of Human Space and Robotic Missions, Space Resources & Industry, Discovery & Space Observation, Spacecraft, Rockets, Propulsion, Space Tourism, Deep Space Communication & Navigation, Space Habitats, and Life Sciences – just to name a few.

‘Substantial’ ocean of water beneath moon’s surface could help create human colony

Posted by in category: space travel

Scientists who retested mineral samples collected during the Apollo moon missions now believe there’s a massive amount of water under the lunar surface – a discovery which may make manned missions to the moon easier than previously thought.

Researchers at Brown University in the US examined glass beads, a type of volcanic crystal gathered during the Apollo 15 and 17 missions in the 1970s, and found they contained similar volumes of water to Earth’s basalt rock.

The leaders of the study, which has been published in Nature Geoscience, cite the parallels as evidence that parts of the moon contain a similarly large amount of water. This, they believe, could be useful for future lunar missions as it means water could potentially be extracted rather than carried from home.
