Did a 5th Giant Planet Mess up the Orbits of Jupiter, Saturn, Uranus and Neptune?

The solar system’s current planetary orbits seem stable, but that’s only because the planets have settled into them over billions of years .  The early solar system was a much different place than that seen today, and for almost 20 years, scientists thought they had a good handle on how it got that way.  But more recently, data had started pointing to some flaws in that understanding – especially about how the giant planets in the outer solar system got where they are today.  Now an international team of astrophysicists thinks they have a better understanding of that process, and they believe it could help solve a long-standing argument about the early solar system. Currently, the best model scientists have for the formation of the solar system is known as the Nice model, after the town in France, where it was first developed in 2005.  As part of this model, the gas giants that currently reside in the outer fringes of this solar system originally orbited what became the sun much more closely with more circular orbits

Engineers Design an Electrical Microgrid for a Lunar Base

For seventy years, Albuquerque-based Sandia National Laboratories has been developing electrical microgrids that increase community resilience and ensure energy security. Applications include the Smart Power Infrastructure Demonstration for Energy Reliability and Security (SPIDERS), designed to support military bases abroad, and independent power systems for hospitals and regions where electrical grids are at risk of being compromised by natural disasters (like hurricanes, flooding, and earthquakes). In the coming years, Artemis Program , NASA will be sending astronauts back to the Moon for the first time since the Apollo Era and establish a “sustained program of lunar exploration.” To ensure that astronauts have the necessary power to maintain their habitats and support operations on the surface, NASA has partnered with Sandia to develop microgrids for the Moon ! This technology could also support future endeavors, like mining, fuel processing, and other activities on the Moon.

‘The Clocks are Telling Lies:’ A New Book from Universe Today Writer Scott Alan Johnston

Scott Alan Johnston (that’s me!) joined the Universe Today team just over a year ago. Since then, I’ve written over 50 space news stories for the website – time flies when you’re having fun! But when I’m not writing articles here on Universe Today, I’m a historian of science, and I recently released a new book about the history of timekeeping. Have you ever wondered why we tell time the way we do?

Artemis 1 Probably won’t Launch Until August

On March 17 th , the Artemis I mission rolled out of the Vehicle Assembly Building (VLB) and was transferred to Launch Complex 39B at the NASA Kennedy Space Center in Florida. This was the first time that a fully-stacked Space Launch System (SLS) and Orion spacecraft were brought to the launchpad in preparation for a “wet dress rehearsal.” To mark the occasion, NASA released a video of the event that featured a new song by Pearl Jam’s Eddie Vedder (“Invincible”)
