A set of photos released by Mars Orbiter Mission last week completes the set of Mars spacecraft observations of the comet. Now we wait for science results!
Yesterday, the much-anticipated comet ISON made its closest pass by Mars. Mars Reconnaissance Orbiter's HiRISE camera is the first to achieve a positive detection of the somewhat-fainter-than-expected comet in its photos.
Yesterday, the Curiosity mission released the video whose potential I got so excited about a couple of weeks ago: the view, from Curiosity, of Phobos transiting Deimos in the Martian sky. In this post, Mark Lemmon answers a bunch of my questions about why they photograph Phobos and Deimos from rovers.
You can be part of a planetwide group photo as Cassini and MESSENGER turn their cameras Earthward on July 19.
A recently discovered comet, C/2013 A1 (Siding Spring), is going to be passing very close to Mars on October 19, 2014. Does it pose a risk to spacecraft?
Deep Impact has made the first space-based observations of comet ISON.
A recently launched Earth-observing satellite is using the stars to practice its pointing, and caught a neat animation of Jupiter.
Space probes grant us perspective, the ability to see our place within the vastness of the solar system. But opportunities to see all of the solar system's planets in one observation are rare. In fact, there's only been one opportunity on one mission to see the whole solar system at once, until now.
Three years after New Horizons flew past Jupiter on its way to Pluto, the spacecraft has imaged the giant planet again.
A very pretty picture of a moon among stars. Happy 2009, everyone!
I received the following question by email last week:
