back to article Here's how fast a spacecraft should fly to successfully detect amino acids erupting from Enceladus

Future spacecraft flying close to Enceladus may be able to detect amino acids, an essential class of organic compounds for life on Earth, in the explosive plumes erupting from the moon's surface, a new study suggests. Enceladus, the sixth-largest moon orbiting Saturn, is of particular interest to astronomers hunting for …

    How fast is that relative to...

    I can only understand velocity in terms of a sheep in a vacuum. We talking 1 SIV, 0.5 SIV... what?

      "velocity in terms of a sheep in a vacuum

      Unfortunately the unit is misdefined according to recognised physics.

      Speed of light (c) divided by wooldrag (Wd) + Welshmen (Wm), where wooldrag is a species-defined drag coefficient determined by the length and pliability of the fleece

      In vacuum, there will be no wooldrag, so the only relevant parameters are speed of light and total mass (sum of M(sheep) and Mtot(Welshmen).

      Screw a fly-by. Let's have a sheep powered lander.

      as long as it does not exceed R17 it should be fine

    Spectrometer

    I think the article needs to point out that the "spectrometer" is not looking at an electromagnetic spectrum.

    It' is, presumably, a Mass Spectrometer, which measures the mass of ionised molecules.
