Elon Musk says Starship SN8 prototype will have a nosecone and attempt a 60,000-foot return flight

Posted by in categories: Elon Musk, space travel

– TechCrunch


Elon Musk has shared some details about future testing of Starship, the SpaceX launch vehicle currently being developed by the company at its Boca Chica, Texas facility. Recently, SpaceX has completed short, 150 meter (just under 500 feet) test flights of two earlier Starship prototypes, SN5 and SN6 – and SN8, which is currently set to be done construction “in about a week” according to Musk will have “flaps & nosecone” and ultimately is intended for a much higher altitude test launch.

The prototypes that SpaceX has flown and landed for its so-called ‘short-hop’ tests over the past few weeks have been full-sized, but with a simulated weight installed on the top in place of the actual domed nosecone that will perch atop the final production Starship and protect any cargo on board. SN5 and SN6, which are often compared to grain silos, are also lacking the large control flaps on either side of the nosecone that will help control its flight. SN8 will have both, according to Musk.

Humanity’s Babel Tower: Space Elevator

Posted by in categories: business, space travel

In the book of Genesis, the Bible recounts the Babel tower that, once built, would allow humanity to do whatever it wishes. In this video, I will go over how humanity’s first space elevator will revolutionize human progress in space exploration and colonization. I will also go over the risks of a possible space elevator.

Quiet Anthropocene, quiet Earth

Posted by in category: biotech/medical

Our planet vibrates incessantly, sometimes with notable but more often with imperceptible intensity. Conventional seismology attempts to decipher vibrational sources and path effects by studying seismograms—records of vibrations measured with seismometers. In doing so, scientists seek either to understand the tectonic processes that lead to strong ground motions and earthquake failure (1) or to probe otherwise inaccessible planetary interiors (2). Progress in these areas of research typically has relied on the rare and geographically irregular occurrence of large earthquakes. However, anthropogenic (human) activities at Earth’s surface also generate seismic waves that instruments can detect over great distances. On page 1338 of this issue, Lecocq et al. (3) report on a quieting of anthropogenic vibrations since the start of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic.
