United Launch Alliance is staging rockets at launch complexes on both the West Coast and the East Coast for the first time since November 2022.
Crew-12's timeline has been unusually dynamic.
Sometimes humans get ahead of ourselves. We embark on grand engineering experiments without really understanding what the long-term implications of such projects are. Climate change itself it a perfect example of that - no one in the early industrial revolution realized that, more than 100 years later, the emissions from their combustion engines would increase the overall global temperature and risk millions of people's lives and livelihoods, let alone the impact it would have on the species we share the world with. According to a new release from the Salata Institute at Harvard, we seem to be going down the same blind path with a different engineering challenge in this century - satellite megaconstellations.
"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate."
The Winter Hexagon encompasses the brightest winter stars. Near Orion, the Big Dog prances and the Hare crouches. And the moonless dark this week opens telescopic deep-sky depths.

With fewer cars on the road, planes in the air and factories running, the skies seemed cleaner during the Covid-19 pandemic. However, while there was a decline in pollutants such as nitrogen dioxide, scientists were surprised to see that methane surged in the early 2020s and then dropped – and now they know why.
The James Webb Space Telescope (JWST ) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the Universe has evolved from the earliest cosmological epoch to the present. When Webb first trained its advanced optics and instruments on the early Universe, it discovered a new class of astrophysical objects: bright red sources that were dubbed "Little Red Dots" (LRDs). Initially, astronomers hypothesized that they could be massive star-forming regions, but this was inconsistent with established cosmological models.
From spaghettified convicts to doomed interplanetary liners, these space movies really pile on the misery.
Humanity has worked itself into a position where we can detect a single high-energy particle from space and wonder where in Nature it came from. Billions of people likely don't care at all about such matters, but for those that are naturally curious and are fortunate enough to have the time to indulge their curiosity, an extremely energetic neutrino detected in 2023 was a remarkable event, and may even turn out to be an historic one.
Ionized clouds give the impression of flames surrounding the star AE Aurigae.
China will work on establishing space-based data centers as a part of a larger five-year plan to expand the nation's already significant presence in space.
