“Worm” Welcome for Artemis I Rocket and Spacecraft

Posted by in category: space travel

NASA is headed back to the Moon as part of the Artemis program – and the agency’s “worm” logo will be along for the ride on the first integrated mission of the powerful Space Launch System (SLS) rocket and Orion spacecraft. Teams at NASA’s Kennedy Space Center in Florida have applied the historic logo in bright red on visible parts of the Artemis I rocket and spacecraft.

SpaceX Boca Chica — Super Heavy Forward Dome Sleeved

Posted by in categories: materials, space travel

The first Super Heavy prototype has entered assembly operations, with the forward barrel sleeved and the fuel stack section spotted. The LR1600/2 crane (aka Tankzilla) continued to grow, and Orbital Launch Pad construction continued with more concrete being pumped into the legs. Starships SN5 and 6 remain outside after having been moved out of the High Bay yesterday, and work continued around the site.

Green technology: the man-made leaf that can produce oxygen

Posted by in categories: materials, space travel

Here at OVO we’re always keeping our eye out for the latest cutting-edge tech that might benefit the environment. That’s why we’re incredibly excited about the news that Julian Melchiorri, a design student at the Royal College of Art, has created the first man-made, biologically functional leaf. Christened ‘The Silk Leaf’, it’s the ultimate in ‘green’ technology in more ways than one.

The leaf contains chloroplasts taken from real plant cells, which are suspended in a silk protein material. When this comes into contact with carbon dioxide, water and light, it converts it into oxygen, just like a real plant.

U.S. DARPA tasks Gryphon with nuclear thermal propulsion system

Posted by in categories: engineering, military, space travel

Gryphon provides digital engineering, analytics, cyber and cloud solutions to U.S. security organizations. It was awarded a $14million DARPA task order to support the development and demonstration of an uranium-based Nuclear Thermal Propulsion (NTP) System.

The system is a part of the Demonstration Rocket for Agile Cislunar Operations (DRACO) program and will enable the U.S. military to operate spacecraft in cislunar space, Gryphon said. The cislunar space is the region outside the Earth’s atmosphere and just beyond the Moon’s orbit.

“A successfully demonstrated NTP system will provide a leap-ahead in space propulsion capability, allowing agile and rapid transit over vast distances as compared to present propulsion approaches,” said Gryphon’s Chief Engineer Dr. Tabitha Dodson.

SpaceX has busy manifest of Dragon missions

Posted by in category: space travel

SpaceX has a busy schedule of Dragon missions carrying cargo and crew to the ISS through next year, with some use of reused spacecraft.


WASHINGTON — SpaceX is preparing for a busy schedule of Dragon missions carrying cargo and crew to the International Space Station through next year, a manifest that will make at least some use of reused spacecraft.

At a Sept. 29 NASA briefing, Benji Reed, senior director of human spaceflight programs at SpaceX, said that schedule of missions means there will be at least one Dragon spacecraft, and sometimes two, docked to the station continuously through the end of 2021 after the launch of the Crew-1 Crew Dragon mission, currently scheduled for Oct. 31.

Another Starship Test Tank is Pushed to the Limit and Explodes

Posted by in category: space travel

SpaceX just passed another milestone with the SN7.1 test tank, which they tested to failure by pressurizing it until it exploded.


They say that failure can be the greatest teacher of all, and it’s easy to see why. Those who learn from their mistakes become informed as to what can go wrong, and will develop the necessary strategies to avoid making the same mistake in the future. This philosophy is also at the core of SpaceX rapid-prototyping process, where full-scale models of the Starship and its components are tested to the point of failure.

Review on Gravitational wave propulsion

Posted by in categories: cosmology, nuclear energy, physics, space travel

Gravitational Wave Propulsion 🤔 ⤵️ check the abstract.


This paper sums up aftereffects of past examinations, including proposed models, so as to construct an advanced hypothetical structure for Gravitational Wave Propulsion. The structure com prises of groups of generators of gravitational waves, which have been hypothesized yet require experimentation, and models of push age. High effectiveness generators depend on cognizant sources, for example synchronized MEMS oscillators, the HTSC Gaser, in light of cognizant turn 2 changes in s-wave/d-wave super conductors, and the atomic electromagnetic wave to gravitational wave up-changing over transducer, in view of dineutrons. After gravitational wave age is effectively demonstrated in the research center, it will be pos-sible to apply an idea created in the field of cosmology. It was discovered that the back-ground vitality thick ness may offer mass to the graviton, which thus may permit gravi tons to produce push. Nearby foundation vitality thickness can be expanded by accusing materials of high dielectric steady in close ness to the wave producing components. Centered Gravitational Waves may likewise create singularities, where the radiation is changed over into a coulomb-like gravitational field. Gravitation al singularities will set a n-body floating framework among them selves, the rocket, and the rest of the assortments of the universe, with clear propulsive impacts. Uses of the current examination will prompt an extraordinary drive framework fit for empowering the quick investigation of the nearby planetary group, the neigh borhood star framework, and potentially the entire system. On a general basis, a vehicle traveling in space requires energy and a reaction mass to accelerate and reach useful speeds. Usually the reaction mass is the mass of the pro- pellant, which in most circumstances has also the role of energy source. Vehicles that are not required to carry re- action masses are more efficient and light weight, but con- ventional ones are limited in scope. It is a fact that, after extraordinary developments, space travel by rocket tech nology has reached its limits and a new paradigm is re- quired to make a big step forward in space propulsion; a step that should enable the exploration of nearby star systems and possibly the whole galaxy. These goals may seem unreachable with the current understanding of physics. Anyway with an open mind and a prag matic approach, it is well known that we are dealing with opinions that are often suggested by the lack of interdisciplinary approach es to complex problems. It often happened that when so called theoretical limits were found wrong, accidental dis- coveries have shown why the good theory was errone- ously applied the first time. An alternative to accidental discoveries are pieces of knowl Review on Gravitational wave propulsion Ching Lee University of Trento, Italy edge gathered from hun- dreds of research papers from different disciplines com- bined in an unusual way to create new concepts. They are normally rejected by experts of their single research field, thus painstaking efforts are required to simply communi- cate the new concept and let it grow in the laboratories. At the and of the last century numerous theoretical efforts have started to show that Gravitational Waves (GWs) have not only astronomical and astrophysicalrelevance, but they also have technological applica tions. Among them, sev- eral theories have approaches identified for telecommuni- cation, imaging, material processing, and space propul- sion. This paper summarizes results of past analyses, in cluding proposed examples, in order to build a modern theoreti cal framework for Gravitational Wave Propulsion. The framework consists of families of generators of gravitational waves, which have been theorized but still require experimentation, and models of thrust generation. High efficiency generators are based on co  herent sources, for instance synchronized MEMS oscillators, the HTSC Gaser, based on coherent spin-2 transitions in s-wave/d wave superconductors, and the nuclear electromagnetic wave to gravitational wave up-converting transducer, based on dineutrons. After gravitational wave generation is successfully proven in the laboratory, it will be pos- sible to apply a concept developed in the field of cosmology. It was found that the back- ground energy density may give mass to the graviton, which in turn may allow gravitons to produce thrust. Local background energy density can be increased by charging materials with high dielectric constant in close proximity to the wave generating elements. Focused Gravita tional Waves may also produce singularities, where the radiation is converted into a coulomb-like gravitational field. Gravitational singularities will set an n-body gravitating system among them selves, the spacecraft, and the remaining bodies of the universe, with obvious propulsive effects. Applications of the present anal ysis will lead to a unique propulsion system capable of enabling the fast exploration of the solar system, the local star system, and possibly the whole galaxy proposed models, so as to construct an advanced hypothetical structure for Gravitational Wave Propulsion.
