    Now that's what I call a good return on investment !!
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I use 56% silver on everything except steel.

    Did you really need the " If you were a real tech " ??

    Vacuum Technology:
    CRUD = Contamination Resulting in Undesirable Deposits.
    CRAPP = Contamination Resulting in Additional Partial Pressure.

    Change your vacuum pump oil now.

    Test. Testing, 1,2,3.

    NASA lunar orbiter to image Chandrayaan 2 landing site


    This mosaic of the near side of the moon was created using data from NASA’s Lunar Reconnaissance Orbiter. Credit: NASA

    NASA’s Lunar Reconnaissance Orbiter will try to locate India’s Vikram lander on the moon during a flyover of the landing site Tuesday. Indian space officials said they found the disabled spacecraft on the moon using the country’s own Chandrayaan 2 orbiter, but declined to release any images.

    LRO’s high-resolution camera has taken aerial images of the Apollo landing sites with enough clarity to resolve the astronauts’ footprints left on the moon more than 40 years earlier. The NASA orbiter’s camera has also imaged China’s Chang’e 3 and Chang’e 4 landers on the moon, and located the crash site of the Israeli Beresheet spacecraft earlier this year.

    MIT Science Reporter—"Computer for Apollo" (1965)

    This 1965 MIT Science Reporter television program features the Apollo guidance computer and navigation equipment, which involve less than 60 lbs of microcircuits and memory cores. Scientists and engineers Eldon Hall, Ramon Alonzo and Albert Hopkins (of the MIT Instrumentation Laboratory) and Jack Poundstone (Raytheon Space Division in Waltham MA) explain and demonstrate key features of the instruments, and detail project challenges such as controlling the trajectory of the spacecraft, the operation of the onboard telescope, and the computer construction and its memory. The program was presented by MIT in association with WGBH-TV Boston, and hosted by MIT reporter John Fitch; it was produced for NASA. MIT Museum Collections.
