In 1979, the Voyager 1 probe took a stunning series of images on its final approach to Jupiter. Thirty-five years later, almost to the day, a group of seven Swedish amateur astronomers set out to replicate this odyssey, but with images taken with their own ground-based telescopes.
Today I received an email notification of new public releases of some image data sets. I always love seeing new public space image data, but this notification was bittersweet: it included the first public release of the very last image data returned to Earth by Deep Impact, of a distant comet ISON.
Curiosity took a new self-portrait on sol 613. This post contains a tip for would-be Curiosity image processors on how to make their Curiosity mosaics better: removing the smearing effect of bright objects in MAHLI photos.
The Cassini mission has already returned an array of images of other solar system members from Saturn orbit: Earth (and the Moon), Venus, Mars, and Jupiter. It’s time to add another world to that list!
Imagine yourself on a windswept landscape of rocks and red dust with mountains all around you. The temperature -- never warm on this planet -- suddenly plunges, as the small Sun sets behind the western range of mountains.
While climbing Murray Ridge, Opportunity enjoyed a major cleaning event that has left the rover's solar panels more dust-free than they have been in years. The rover captured a pretty panorama of the newly clean deck with its Pancams, and James Sorenson processed the version shown here.
It's happened again; I went into the Cassini image archive looking for something specific and wound up spending several hours playing with totally unrelated image data. Here are several beautiful images of the rings from the archives.
Cassini flew past Phoebe on June 11, 2004, on its way to entering Saturn orbit. The flyby was almost perfect but overexposure of some images have prevented color mosaics from being produced. Even though Phoebe's body is gray and dull in color, the absence of color images always provoked me. By using VIMS data, I have now produced color mosaics.
Woo hoo! I've got another cover story in the current (February 2014) issue of Sky & Telescope, in which I try to make sense of the Kuiper belt. This article was motivated by my observation that the discovery of many new things beyond Neptune had, through an ironic chain of events, resulted in our teaching children less about the solar system than we used to.
