Nearby supernova explosions shape the interstellar medium. Ejecta, containing fresh nucleosynthetic products, may traverse the solar system as a transient passage, or alternatively the solar system may traverse local clouds that may represent isolated remnants of supernova explosions. Such scenarios may modulate the galactic cosmic-ray flux intensity to which Earth is exposed. Varying conditions of the traversed interstellar medium could have impacts on climate and can be imprinted in the terrestrial geological record. Some radionuclides, such as ⁶⁰ Fe, are not produced on Earth or within the solar system in significant quantities. Their existence in deep-sea sediments demonstrates recent production in close-by supernova explosions with a continued influx of ⁶⁰ Fe until today.

Nuclides synthesized in massive stars are ejected into space via stellar winds and supernova explosions. The solar system (SS) moves through the interstellar medium and collects these nucleosynthesis products. One such product is ⁶⁰ Fe, a radionuclide with a half-life of 2.6 My that is predominantly produced in massive stars and ejected in supernova explosions. Extraterrestrial ⁶⁰ Fe has been found on Earth, suggesting close-by supernova explosions ∼2 to 3 and ∼6 Ma. Here, we report on the detection of a continuous interstellar ⁶⁰ Fe influx on Earth over the past ∼33,000 y. This time period coincides with passage of our SS through such interstellar clouds, which have a significantly larger particle density compared to the local average interstellar medium embedding our SS for the past few million years. The interstellar ⁶⁰ Fe was extracted from five deep-sea sediment samples and accelerator mass spectrometry was used for single-atom counting.

Space fans are in for a treat later this week.

Five missions are scheduled to launch from Thursday to Sunday (Aug. 27 to Aug. 30), three of them from Florida’s Space Coast.

Tesla CEO Elon Musk has updated the timeline on which he sees batteries enabling electric aircraft coming to maket. He now sees it happening in “3 to 4 years.” Several years ago, Musk, the CEO of both Tesla and SpaceX, said that he had a design for electric vertical take-off and landing (VTOL) a…

Tesla CEO Elon Musk has been talking about the electric plane for a long time. He even said he has an electric vertical take-off and landing (VTOL) aircraft project, though he never went into details about plans to launch it into production.

Unlike a traditional rocket engine, which consists of individually designed parts that are combined together the AI designed rocket engine was 3D printed as one continuous piece. This includes both the combustion chamber where fuel and oxidiser is burned and the surface channels, through which the fuel is circulated to cool the chamber and keep it from overheating.

“In a rocket, the cooling channels are generally welded onto the combustion chamber, which through wear and tear can cause errors and explosions,” explained Hyperganic’s design director Duy-Anh Pham.

For the past number of years I’ve been taking about the rise of so called Creative Machines, Artificial Intelligence (AI) based “innovation” machines, that can design and innovate things for themselves without any human intervention – things such as aircraft parts, chairs, fashion lines, interplanetary rovers, self-evolving robots, and Under Armour trainers. And now those same creative machines have made yet another leap, and again it’s another first for the space industry, after German software company Hyperganic announced they’d developed a 3D printed rocket engine prototype, which was completely designed by AI.

Called “Spinnaker3,” this drag sail isn’t the first to be launched into space. But it is among the first to be large enough for deorbiting the upper stage of a launch vehicle. The Firefly Alpha launch will target an orbit altitude of about 200 miles, but the Spinnaker3 drag sail is capable of providing deorbit capability from orbit altitudes of 400 miles or greater.

WEST LAFAYETTE, Ind. — A rocket is going up into space with a drag sail. The goal? For the drag sail to bring the rocket back to Earth, preventing it from becoming like the thousands of pieces of space junk in Earth’s lower orbit.

SpaceX has fired up the latest prototype of its Starship Mars-colonizing spacecraft, keeping the vehicle on track for a possible test flight this weekend.

If you’re a fan of science fiction, chances are you encountered a few franchises where humanity has spread throughout the known Universe. The ships that allow them to do this, maybe they use a warp drive, maybe they “fold space,” maybe have a faster-than-light (FTL) or “jump” drive.

It’s a cool idea, the thought of “going interstellar!” Unfortunately, the immutable laws of physics tell us that this is simply not possible.

O,.o earth to Mars 12.5 minutes.

A NASA scientist has cooked up plans for a bonkers new rocket engine that can reach close to the speed of light – without using any fuel.

Travelling at such speeds, the theoretical machine could carry astronauts to Mars in less than 13 minutes, or to the Moon in just over a second.
