New Glenn launch: Blue Origin's reusable rocket set for maiden flight (New Scientist)

Quote

Blue Origin, the space company owned by Amazon founder Jeff Bezos, is set to launch its reusable New Glenn rocket for the first time on 10 January. If successful, the rocket could become a rival to SpaceX’s Falcon Heavy rocket, which has become the go-to launch vehicle for companies looking to put large payloads into orbit.

New Glenn is a 98 metre-tall rocket, around the height of a 30-storey building, designed to deliver payloads of up to 45 tonnes to low Earth orbit. It is expected to compete with SpaceX’s Falcon Heavy, which can carry about 64 tonnes of cargo.

The rocket has two stages. The first stage is designed to land on a sea platform, similar to Falcon Heavy, and Blue Origin claims it will be reusable for 25 missions. At the top of the rocket is a disposable upper stage where cargo and mission payloads can be stored.

The Blue Origin first stage was lost during re-entry, so at this stage it's still an expendable.

Meanwhile, the Starship upper stage exploded, but they did successfully capture the main booster. The FAA has grounded the launcher pending an investigation.

A Spiral Found at the Solar System’s Edge—And It’s Full of Surprises

Quote

...a team of scientists recently ran simulations using NASA’s Pleiades supercomputer to model the structure of the Oort Cloud. They incorporated data on the orbits of long-period comets and factored in the gravitational influences not just from the Sun and planets but also from external cosmic forces. The result? A discovery that challenges everything we thought we knew: the inner Oort Cloud may not be a simple sphere after all. Instead, the simulations suggest it forms a spiral disk structure, much like a tiny, frozen version of the Milky Way galaxy. The simulations revealed that this spiral structure extends across the inner region of the Oort Cloud, between 1,000 and 10,000 AU from the Sun. Even more astonishingly, the spiral arms stretch up to 15,000 AU from end to end.
