  • A solar storm can change a satellite’s orbit by changing the atmosphere around it. When energy from the Sun heats Earth’s upper atmosphere, the gas expands, increasing resistance along some orbital paths. A planned Swiss mission will investigate that connection by observing the Sun and the atmosphere from the same spacecraft.

    The May 2024 Gannon geomagnetic storm exposed the operational consequences. An analysis published in the Journal of Spacecraft and Rockets documented thousands of satellites maneuvering after enhanced drag caused altitude losses. Such widespread adjustments complicate tracking and collision avoidance, because predicted encounters must be reassessed using the spacecraft’s changed trajectories.

    Interesting complications!



  • Swift team mourning yet full of gratitude for the observations the telescope made during its 22 years in orbit. Swift blasted off on Nov. 20, 2004, to search for some of the biggest explosions in the universe: gamma ray bursts and supernovas.

    NASA’s article is more informative: 2-year primary mission.

    “Swift was designed as a satellite dedicated to studying gamma-ray bursts, outbursts that came and went so quickly that no one could target them with large telescopes to learn more,” said S. Bradley Cenko, the mission’s principal investigator at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Swift needed to detect and locate gamma-ray bursts, communicate their position to other observatories, and then swing its telescopes around to image the burst locations before their afterglows faded out. This typically took Swift about a minute to do.”

    The completed Swift spacecraft is seen in a clean room at NASA Goddard on Sept. 9, 2003. In front of it, Neil Gehrels, the mission’s first principal investigator, points toward the instruments at the top.


  • She is being kept largely in solitary confinement, she said, “away from other people and the human connections that mean so much to me”.

    Such isolation was its own form of pain, she said, given that she spent the first 28 years on death row in solitary confinement.

    She was 18 at the time of the murder. Most people are hardly the same person that they were that much of their life ago.

    She was neglected by alcoholic parents,[12] and her attorneys said she was exposed to alcohol in the womb.[13] She was raped as a toddler and again at ages 11 and 17.[14][15] She attempted suicide at the age of 12 and in 1991 she was sent to a Juvenile Evaluation Center in Swannanoa, North Carolina

    Yikes.




  • If they aren’t going to have the votes to make it stick, I agree it feels like a waste of time.

    I would like to see really hard lines on ICE, Israel, Iran. Though government shutdown doesn’t hit me personally that hard; we would need to be ready to support vulnerable folks.

    I actually think getting all the evidence ready for criminal prosecution seems helpful. And separately, building local government power.

    But overall, I’m not sure how they can fight an illegal leader from within the legal system, if half the government is also illegal cronies.



  • Interesting content! Is it available as a web page and not PDF?

    Anyway, from the first article:

    Palestinians do not have their own currency. Under the 1994 Paris Protocol, they were locked into using the Israeli shekel, with no central bank of their own to issue money or set monetary policy. […] Since Palestinians clear their money in shekels, Palestinian banks can only settle transactions by routing through Israeli correspondent banks. Those banks process Palestinian transactions only under an indemnity waiver from Israel’s finance ministry, a piece of paper that shields them from legal liability for handling Palestinian-linked money. The waiver has to be renewed on a schedule, which means that a routine bit of financial plumbing doubles as a political switch that someone in a ministry can flip.

    While some people in Gaza have access to Bank of Palestine accounts, many have lost this access or never had it. Cryptocurrency has become one of the most reliable ways to get funds directly to those who need them.
