SpaceX fires up giant new Starship booster ahead of test flight (video)

SpaceX fired up its huge new Starship Super Heavy booster today (Aug. 6), notching an important milestone on the path to flight.

Graphene Could Be A Game Changing Material In Space – With A Bit More Research

Graphene has long been put forward as a wonder material. Undeniably, it has astounding properties – stronger than steel, a better electrical conductor than copper, and lighter than almost anything else with similar properties. And while it’s been partially adopted into space-faring technologies, many use cases remain where a pure form of the material could dramatically benefit the space industry. To detail those opportunities, a group of scientists from the Italian Space Agency recently released a paper that looked at graphene’s role in space exploration – and where it might stand to make an even bigger impact shortly.

Two Stars Orbiting Each Other So Closely They Could Fit Inside the Sun

Astronomers have discovered a pair of star-like objects orbiting each other extremely quickly, with an entire ‘year’ lasting just 1.9 Earth hours. Catchily named ZTF J2020+5033, the system consists of one object which is definitely a small star, and another that straddles the boundary between star and planet. The two objects appear to be very old, and understanding how they came to be orbiting so close together is teaching astronomers more about how solar systems change and evolve.

Some Metal Meteorites Have a Tiny Magnetic Field. But How?

One of the striking things about iron meteorites is that they are often magnetic. The magnetism isn’t strong, but it holds information about their origin. This is why astronomers discourage meteorite hunters from using magnets to distinguish meteorites from the surrounding rock, since hand magnets can erase the magnetic history of a meteorite, which is an important scientific record.

Watch Live: SpaceX plans static test fire of Starship Super Heavy Booster today

SpaceX is getting ready to fire up its Starship Super Heavy Booster 9 for a static test of its liquid methane-fueled Raptor rocket engines. It will be the first test of a new water deluge system installed at the launch pad following the first Integrated Test Flight for the Starship vehicle on April 20.

NASA unveils new website and streaming new service landing later this year

NASA has announced the new "NASA+" streaming service which will offer free event content and videos when it launches sometime later in 2023.

A Bronze Age Arrowhead was Made Out of a Meteorite

It’s sometimes hard to remember that meteorites have been hitting our planets for millions of years. And some of them are made of valuable materials such as titanium or iron. So, theoretically, at least, our bronze and iron age ancestors could utilize these ready-made metallic rocks without having to dig underground to access them, like they would with regular tin or iron veins. Now, a new study of an arrowhead made out of a meteorite points out just how valuable iron age society thought these meteorites were and hints at a trade network that reached farther than archeologists initially thought.

Sun blasts out highest-energy radiation ever recorded, raising questions for solar physics

Using a 24/7 observatory that can detect when charged particles interact with water, scientists identified record-breaking rays coming from the sun.

Giant 'bubbletrons' shaped the forces of the universe moments after the Big Bang, new study suggests

Meet the 'bubbletrons' — theoretical particle accelerators that may have helped build the universe as we know it.

Watch SpaceX launch 22 Starlink satellites tonight

SpaceX will launch 22 more of its Starlink internet satellites tonight (Aug. 6), and you can watch the action live.

Spacecraft, Landers and Rovers Could be Recycled for Parts on the Moon

Additive manufacturing is slowly becoming more and more useful as the technology improves. One of the places it continues its development is in the realm of space exploration. It has long been mooted as an integral part of any in-situ resource utilization (ISRU) efforts and is especially important for ensuring early explorers on the Moon have the right tools and materials they need to survive. The European Space Agency is supporting that research effort, as their Technology Development Element fund supported work by an Austrian company called Incus to develop a 3D printing solution that could reprint metal parts on the Moon.
