Why Solitary Confinement Is The Worst Kind Of Psychological Torture

Posted by in categories: habitats, health, neuroscience

There may be as many as 80,000 American prisoners currently locked-up in a SHU, or segregated housing unit. Solitary confinement in a SHU can cause irreversible psychological effects in as little as 15 days. Here’s what social isolation does to your brain, and why it should be considered torture.

There’s no universal definition for solitary confinement, but the United Nations describes it as any regime where an inmate is held in isolation from others, except guards, for at least 22 hours a day. Some jurisdictions allow prisoners out of their cells for one hour of solitary exercise each day. But meaningful contact with others is typically reduced to a bare minimum. Prisoners are also intentionally deprived of stimulus; available stimuli and the fleetingly rare social contacts are rarely chosen by the prisoners, and are are typically monotonous and inconsiderate of their needs.

Iridium would pay to deorbit its 30 defunct satellites — for the right price

Posted by in category: satellites

WASHINGTON — Iridium Communications completed disposal of the last of its 65 working legacy satellites Dec. 28, while leaving open the possibility of paying an active-debris-removal company to deorbit 30 that failed in the decades since the operator deployed its first-generation constellation.

McLean, Virginia-based Iridium started deorbiting its first constellation, built by Motorola and Lockheed Martin, in 2017, as it replaced them with second-generation satellites from Thales Alenia Space.

Of the 95 satellites launched between 1997 and 2002, 30 malfunctioned and remain stuck in low Earth orbit, according to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics.

Betelguese, one of the brightest stars in the sky, might be on the brink of explosion

Posted by in category: space

INDIANAPOLIS (WTHR) — One of the sky’s brightest stars has been acting a little weird recently.

Betelgeuse, a bright star in the constellation Orion, has been rapidly dimming since the beginning of December. It’s already dimmed by a factor of two, according to the Independent, which makes the change visible to the naked eye. Betelgeuse was once the ninth brightest star in our sky, but after its dimming it doesn’t even break the top 20 anymore, according to the Washington Post.

The star is known as a “variable” star, which means it’s characterized by cycles of brightening and dimming. However, scientists have never recorded it dimming so fast. Astronomers Villanova University say this is an all time low in brightness for the star.

Elon Musk details SpaceX progress on latest Starship spacecraft build and flight timelines

Posted by in categories: Elon Musk, space travel

The holidays might be a time of slowed activity for most companies in the tech sector, but for SpaceX, it was a time to ramp production efforts on the latest Starship prototype — “Starship SN1” as it’s called, according to SpaceX CEO Elon Musk. This flight design prototype of Starship is under construction at SpaceX’s Boca Chica, Texas development facility, and Musk was in attendance over the weekend overseeing its build and assembly.

Musk shared video of the SpaceX team working on producing the curved dome that will sit atop the completed Starship SN1 (likely stands for “serial number 1,” a move to a more iterative naming system and away from the “Mark” nomenclature used for the original prototype), a part he called “the most difficult” in terms of the main components of the new spacecraft. He added that each new SN version of the rocket SpaceX builds will have minor improvements “at least” through the first 20 or so versions, so it’s clear they expect to iterate and test these quickly.

As for when it might actually fly, Musk said that he hopes this Starship will take off sometime around “2 to 3 months” from now, which is still within range of the projections for a first Starship high-altitude test flight given by the CEO earlier this year at the unveiling of the Starship Mk1 prototype. That prototype was originally positioned as the one that would fly for the high-altitude test, but it blew its top during testing in November and Musk said they’d be moving on to a new design rather than repair or rebuild the Mk1.
