Philae’s First Look After A Bouncy Landing

Posted on November 13, 2014 by Bob TrembleyNovember 13, 2014

Bob and his telescope

* Lifelong amateur astronomer
* Volunteer NASA/JPL Solar System Ambassador
* Outreach Officer for the Warren Astronomical Society
* Blogger for the Vatican Observatory Foundation

I do a lot of astronomy outreach; I lecture about astronomy and space science, and set up his telescopes at schools, planetariums, conventions, and other venues.

I am fantastically interested in asteroids and near-Earth objects (NEOs), and a HUGE fan of space visualization applications like Kerbal Space Program and NASA Eyes on the Solar System.

I am determined to improve the teaching of astronomy, space science, and space history throughout Michigan, and the U.S.

  • In the Sky This Week – January 19, 2021
    I know quite a few astrophotographers! During online meetings of the Warren Astronomical Society, members show astrophotos they've recently captured and processed; even their "bad ones" are awe-inspiring! Here's a beautiful pic by Adrian Bradley: A couple of these astrophotographers regularly livestream their telescope sessions for the public to view: Doug Bock & Dr. Brian […]

    Venus appears very low above the southeastern horizon before sunrise. Jupiter, Saturn and Mercury continue to form a triple conjunction in the southwestern sky at dusk - Saturn may be a bit difficult to see; Mercury appears slightly higher above the horizon each evening.

  • In the Sky This Week – January 5, 2021
    For the images in this week's "In the Sky" post, I turned light pollution off in Stellarium - these images show a multitude of stars you cannot see from an urban or suburban locations. I remember camping at a VERY dark sky location in Michigan's Upper Peninsula, and not being able to find any familiar […]

    Jupiter and Saturn appear in the southwestern sky at dusk, getting closer getting closer to the Dec. 21 conjunction with each passing day! The waxing crescent Moon joins the pair of planets on Dec. 16 & 17. Venus appears in the southeastern predawn sky all week, getting closer to the horizon with each passing day. […]

    A small satellite mission to understand the lunar water cycle – detecting and mapping water on the lunar surface in order to investigate how its form, abundance, and location relate to geology – has received NASA approval to proceed with the next phase of its development. On Nov. 24, the Lunar Trailblazer, a mission selected […]

    Jupiter and Saturn appear in the southwestern sky at dusk, getting closer together with each passing evening. Mercury and Venus appear in the east-southeastern predawn sky all week - Mercury may be difficult to spot this week being so near the horizon. Mars appears high in the southeastern sky after sunset - the waxing gibbous […]
