Even if they were dozens of light-years away, two colliding neutron stars could create a powerful enough explosion to wipe out life on Earth.
At least, that’s according to a recent paper published in The Astrophysical Journal, in which a team of researchers concluded that a kilonova could pose a major threat to Earth-like planets, even at formidable interstellar distances.
A kilonova is usually the result of a collision involving two neutron stars within a binary system, or when a neutron star and a black hole merge. These collisions release brain-melting amounts of electromagnetic radiation in the form of gamma-ray bursts.
This is a sci-fi documentary, looking at how warp drive technology and warp spaceships work. As well as the negative energy needed to travel at warp speed. The faster than light journey to Mars takes 18.6 seconds, but how long does it take to reach the nearest black hole?
It is a journey showing the future science of space travel, exploration, and future space technology.
The SpaceX Dragon spacecraft undocked from the space-facing port of the International Space Station’s Harmony module at 9:20 a.m. EST over the Pacific Ocean, west of Ecuador, to complete the third all-private astronaut mission to the orbiting laboratory, Axiom Mission 3 (Ax-3).
Dragon is slowly maneuvering away from the orbital laboratory into an orbital track that will return the astronaut crew and its cargo safely to Earth, targeting a splashdown off the coast of Daytona, Florida, at approximately 8:30 a.m. EST Friday, Feb. 9.
Ax-3 astronauts Michael López-Alegría, Walter Villadei, Marcus Wandt, and Alper Gezeravci will complete 18 days aboard the orbiting laboratory at the conclusion of their mission. The SpaceX Dragon will return to Earth with more than 550 pounds of science and supplies, including NASA experiments and hardware.
Launching rockets into space with atomic bombs is a crazy idea that was thankfully discarded many decades ago. But as Richard Corfield discovers, the potential of using the energy from nuclear-powered engines to drive space travel is back on NASA’s agenda.
In 1914 H G Wells published The World Set Free, a novel based on the notion that radium might one day power spaceships. Wells, who was familiar with the work of physicists such as Ernest Rutherford, knew that radium could produce heat and envisaged it being used to turn a turbine. The book might have been a work of fiction, but The World Set Free correctly foresaw the potential of what one might call “atomic spaceships”
The idea of using nuclear energy for space travel took hold in the 1950s when the public – having witnessed the horrors of Hiroshima and Nagasaki – gradually became convinced of the utility of nuclear power for peaceful purposes. Thanks to programmes such as America’s Atoms for Peace, people began to see that nuclear power could be used for energy and transport. But perhaps the most radical application lay in spaceflight.
Veteran autonomous delivery robot developer Starship Technologies announced it had raised an additional $90 million in funding to help expand its micro-logistics service to additional territories around the globe.
Starship Technologies was founded in 2014 by Skype co-founders Ahti Heinla and Janus Friis based on the idea that autonomy can help many of the challenges in last-mile deliveries. The company’s L4 autonomous delivery robots have completed over six million trips to date, transporting meals, packages, groceries, and important documents to students and other customers.
In August 2023, that mileage total was five million, operating in 30 different areas. Today, Starship’s robots have expanded to 80 locations worldwide, including the US, UK, Germany, Denmark, Estonia, and Finland.
Sidewalk delivery robot services appear to be stalling left and right, but a pioneer in the concept says it is profitable and has now raised a round of funding to scale up to meet market demand. Starship Technologies, a startup out of Estonia that was an early mover in the delivery robotics space, has picked up $90 million in funding as it works to cement its position at the top of its category.
This latest investment round is being co-led by two previous backers: Plural, the VC with roots in Estonia and London that announced a new $430 million fund last month; and Iconical, the London-based investor backed by Janus Friis, the serial entrepreneur who was a co-founder of Skype, and who is also a co-founder of Starship itself.
Read about NASA’s new instrument for landing on other worlds!
Landing on planetary bodies is both risky and hard, and landing humans is even riskier and harder. This is why technology needs to be developed to mitigate the risks associated with landing large spacecraft on the Moon and other planetary bodies we plan to continue exploring, both in the near and distant future. This is what makes the Nova-C lunar lander from Intuitive Machines—which is scheduled to launch to the Moon on February 13 and also called Nova-C (IM-1) —so vital to returning humans to the Moon. One of its NASA science payloads will be the Navigation Doppler Lidar (NDL), which will serve as a technology demonstration for future landers to help them navigate risky terrain and land safely.

It’s been more than three years since the National Aeronautics and Space Administration made space-grown lettuce an item on the menu for astronauts aboard the International Space Station. Alongside their space diet staples of flour tortillas and powdered coffee, astronauts can munch on a salad, grown from control chambers aboard the ISS that account for the ideal temperature, amount of water and light that plants need to mature.
But there is a problem. The International Space Station has a lot of pathogenic bacteria and fungi. Many of these disease-causing microbes at the ISS are very aggressive and can easily colonize the tissue of lettuce and other plants. Once people eat lettuce that’s been overrun by E. coli or Salmonella, they can get sick.
With billions of dollars poured into space exploration each year by NASA and private companies like SpaceX, some researchers are concerned that a foodborne illness outbreak aboard the International Space Station could derail a mission.
In the XXI century, the world of orbital launchers has started a revolution, a fundamental change of paradigm: the replacement of expendable rockets with reusable ones is well underway. This presentation summarizes the situation at the beginning of year 2024.
A short bio. Alberto Cavallo is an Electrical Engineer, graduated at the Politecnico di Torino in 1985. He began his activity with designing electric systems in Fiat Engineering, the engineering and construction company of the FIAT Group, moving soon to control and automation systems in the same company. He was involved in all business areas of the company, which included revamping and new projects of car factories for the FIAT Group as well as large infrastructures, power and cogeneration plants for external clients. Among the projects of that time were the new FIAT factories in Melfi and Pratola Serra, the high speed railways Torino-Milano and Bologna-Firenze, the district heating system of Torino Sud, combined cycle power plants for several hundred megawatts in Italy and in Brazil. Since Fiat Engineering was transferred from the FIAT Group to a new EPC group and then merged with a large EPC company in Milan, he has been involved in large oil and gas and petrochemical projects all over the world. Besides his professional activity, he has always taken part in several cultural activities. He was a member of the Associations of Alumni of the Liceo Classico Vittorio Alfieri of Turin, active in promoting humanistic culture as well as its connection to the technical and scientific area. He manages his own website www.eurinome.it (in Italian only) about philosophy, science and politics/geopolitics. Due to this he got in contact with Adriano Autino and his TDF, then becoming one of the founding members of Space Renaissance International. Besides several papers in his professional area he has written several articles for his own site, for TDF and SRI, coauthoring the book “Three Theses for the Space Renaissance” with Adriano Autino and Patrick Q. Collins. He is currently member of the Board of SRI.
