8. The Discovery Of Io
In many ways, Io is one of the more popular moons of Jupiter. It’s been referenced many a time as we’ll note later. But how did we learn about this very special moon?
The first reported observation of Io was made by Galileo Galilei on 7 January 1610 using a 20x-power, refracting telescope at the University of Padua. However, in that observation, Galileo could not separate Io and Europa due to the low power of his telescope, so the two were recorded as a single point of light. Io and Europa were seen for the first time as separate bodies during Galileo’s observations of the Jovian system the following day, January 8th, 1610 ( this is used as the discovery date for Io by the IAU).
The discovery of Io and the other Galilean satellites of Jupiter was published in Galileo’s Sidereus Nuncius in March 1610. In his Mundus Jovialis, published in 1614, Simon Marius claimed to have discovered Io and the other moons of Jupiter in 1609, one week before Galileo’s discovery. Galileo doubted this claim and dismissed the work of Marius as plagiarism. Regardless, Marius’s first recorded observation came from 29 December 1609 in the Julian calendar, which equates to January 8th, 1610 in the Gregorian calendar, which Galileo used. Given that Galileo published his work before Marius, Galileo is credited with the discovery.
But the end of the “discovery” did not end there. Because for basically 250 years various astronomers tried to learn more about Io. But because of its place in space all they could usually see was a ball of light. It would take a while for them to start to parse out the details of the moon.
Improved telescope technology in the late 19th and 20th centuries allowed astronomers to resolve (that is, see as distinct objects) large-scale surface features on Io. In the 1890s, Edward E. Barnard was the first to observe variations in Io’s brightness between its equatorial and polar regions, correctly determining that this was due to differences in color and albedo between the two regions and not due to Io being egg-shaped, as proposed at the time by fellow astronomer William Pickering, or two separate objects, as initially proposed by Barnard. Later telescopic observations confirmed Io’s distinct reddish-brown polar regions and yellow-white equatorial band.
Telescopic observations in the mid-20th century began to hint at Io’s unusual nature. Spectroscopic observations suggested that Io’s surface was devoid of water ice (a substance found to be plentiful on the other Galilean satellites).
So as you can see, this wasn’t just a discovery of trying to find the moon, but to try and understand what it was and what it was like in regards to its very nature. Which would be further expanded upon in the future via attempts to explore the moon with probes and satellites.
7. The Exploration of Io Part 1
In the late 1960s, a concept known as the Planetary Grand Tour was developed in the United States by NASA and the Jet Propulsion Laboratory (JPL). It would allow a single spacecraft to travel past the asteroid belt and onto each of the outer planets, including Jupiter, if the mission was launched in 1976 or 1977. However, there was uncertainty over whether a spacecraft could survive passage through the asteroid belt, where micrometeoroids could cause it physical damage, or the intense Jovian magnetosphere, where charged particles could harm sensitive electronics.
