  • Venus Climate Orbiter Akatsuki’s Mission Has Ended

    Japan’s Venus Climate Orbiter Akatsuki was launched on May 21, 2010, and started its active mission in 2015 after an initial orbital insertion failure. Since that time, Akatsuki has continuously observed Venus from orbit until issues began to crop up in 2024 when contact was lost in April of that year due to attitude control issues. Japan’s space agency, JAXA, has now announced that the mission has officially ended on September 18, 2025, after a period of trying to coax the spacecraft back into some level of functionality again.

    The Akatsuki spacecraft had six instruments, consisting of cameras covering the visible spectrum, ultraviolet and infrared spectra, as well as an oscillator for radio occultation experiments.

    All primary mission goals were successfully completed in April of 2018, but engineers determined Akatsuki was capable of lasting at least another few years. This puts it well past its original design lifespan, and has provided us with much more scientific data than we could have hoped for.

    Unfortunately, the shutdown of Akatsuki represents the end of the last active Venus mission, with much uncertainty surrounding any potential upcoming mission to Earth’s near-twin planet. The next potential mission is the Venus Life Finder, as an atmospheric mission penciled in for a 2026 launch. It would take at least until 2028 for a potential orbiter mission to launch, so for the foreseeable future Venus will be left alone, without its artificial moon that has kept it company for a decade.

    I enjoyed and appreciated reading this post.

    "I realized almost immediately that GNU/Linux and FreeBSD were so similar they were completely different."

    This right here.

    My initial impression with in 2006 was quite similar. Of course, back then was a much different beast than what it has evolved (mutated?) into today.

    Had I not pursued Linux system administration as a career, I *probably* would have stuck with FreeBSD.

    We can make all the technical comparisons between the two OSes all day long but what drove my interest and enthusiasm are (1) the documentation and (2) the community.

  • @stefano Don’t bother filing a bug report. They will act stupid. Probably they are stupid about it. They think it is a bug. Actually the author probably wrote a program he knew was not a solution to the problem but which he could do on deadline and which was good enough for his job at HP.

  • @stefano Here is something new for you to be upset about, though, which affects everyone, Linux, BSD, illumos alike. I have been upset about it for over 20 years.

    Read ‘man 5 fonts-conf’ or whatever your equivalent is. Read it carefully under ‘FONT MATCHING’. What it says is that a font is not chosen as you wished, but instead RANDOMLY. You are only LUCKY if you get the font you wished.

    And if you experiment long enough you will find this is true.

    Fontconfig is unfixable and must be scrapped.
