  • Space as Solace During a Government Shutdown

    Space as Solace During a Government Shutdown

    The recent space activities I’m writing and posting about provide solace during this government shutdown that has furloughed most NASA and related departments employees and contractors.

  • “Meet Ultima Thule”

    “Meet Ultima Thule”


    And Ultima and Thule, according to New Horizons’ principal investigator Alan Stern at today’s NASA press briefing, the informal names the team have given the two lobes of the red object out in the Kuiper Belt New Horizons spent New Year’s encountering. The contact binary connected by a neck of material indicates two objects that came together and stuck sometime in the distant past when these kinds of interactions were leading elsewhere in the solar system to accretions that would eventually form the planets and their moons.

  • New Year, New Day, New Image of Ultima Thule

    New Year, New Day, New Image of Ultima Thule

    During a morning press briefing aired on NASA TV on New Year’s Day 2019, New Horizons mission team leaders revealed the latest best image of Ultima Thule. Still a blur, the Kuiper Belt body’s shape is more apparent in this latest image. Still unclear: are the two lobes connected or are they in fact two separate objects orbiting each other? The pole of the object was pointed toward the spacecraft, meaning Ultima Thule rotates from that perspective like a propellor. Artist and planetary scientist James Tuttle Keane has helped visualize this geometry in his illustration included next to the image.

    As we do, the HiRISE team took a high resolution image of the InSight lander safe on the surface of Mars.

  • Pluto Before New Horizons

    Consider what those of us can see in the night sky with healthy eyes, without any tools, far from city lights. Away from the dazzle of Sun’s day the Moon at night is, of course, the brightest above all. The visible stars make an obvious and fixed, so it seems, pattern that fills the celestial hemisphere. […]

  • Pluto and Charon in Color and in Tantalizing Detail

     [Post edited on Monday, June 22, 2015 to correct my misunderstanding about the provenance of the remarkable color image below.] Tonight I was browsing the latest raw images of Pluto and Charon taken by New Horizons today from only 27.7 million kilometers away and I realized that when you zoom in, Charon is just beginning […]

  • New Horizons at Pluto

    This is it! Pluto is the last of the classical nine planets to be visited by a spacecraft from Earth. The New Horizons spacecraft will take close-up images and capture other useful data as it speeds by Pluto and its moons on July 14, 2015. This will complete the imaging grand tour of our solar system […]

  • Rosetta at 21 Lutetia

    The Rosetta spacecraft has returned the first images from its flyby of the asteroid 21 Lutetia. The image on the right was taken while the spacecraft was approximately 80,000 kilometers away and it shows a lumpy, cratered world. Lutetia is approximately 100 km in diameter. It is the largest asteroid yet visited by a spacecraft. […]

    Along with first images, anaglyphs and initial data results from Rosetta’s successful flyby of Asteroid (2867) Šteins, mission team members put together an animation of the flyby: More Information Rosetta Rosetta Blog Press Release: “Steins: A diamond in the sky“ Related Books [amazon-product]0387726721[/amazon-product] [amazon-product]1402025726[/amazon-product] [amazon-product]038777517X[/amazon-product]

  • Šteins Up Close

    Hours after its successful flyby of “the jewel of the solar system”, the robotic traveler Rosetta continues to return data from the encounter. From a point of light discovered in 1969 into a world of new vistas, here is Asteroid (2867) Šteins: At a press conference to announce preliminary results and to show the first […]

  • Asteroid (2867) Šteins Flyby Coming

    Rosetta, the European Space Agency (ESA) spacecraft on its way to orbit and deploy a lander on a comet, is now approaching Asteroid (2867) Šteins. The flyby will bring the spacecraft within 800 km of Šteins on Friday evening, September 5, 2008. The ESA will provide a webcast about the event beginning on September 06, […]

  • Planetary Provenance – Venus

    Venus is the Earth-that-could-have-been and the Earth-that-still-might-be.  Our so called sister planet orbits second from the Sun. Cloudy, hot, and unhospitable to life as we know it, Venus demonstrates as well as Mars why comparative planetary science can greatly improve understanding of our own planet. The greenhouse effect on Venus results in a poorly understood phenomena […]

  • Planetary Provenance – Mercury

    I will be speaking at the Sunday, September 7 meeting of the Humanist Society of Greater Phoenix about “Images of Mars and Interplanetary Science.” This series of posts in preparation for the event will explore current spacecraft activities in planetary science. After the astronomy revolt that left the solar system with eight planets, four dwarf […]

  • Closest Enceladus Flyby Yet

    Cassini took this image of Enceladus’ water ice plumes on November 27, 2005.  New pictures and other data from the most recent flyby on Wednesday, March 12, 2008 are expected on Thursday, March 13, 2008.  Image Credit: NASA/JPL/Space Science Institute – “Jet Blue“ NASA’s Cassini spacecraft has successfully completed the closest flyby of Saturn’s mysterious […]

  • Five Planets Make Record System

    Image Credit: NASA – “Plentiful Planetary System” – “This artist’s concept shows four of the five planets that orbit 55 Cancri, a star much like our own.” NASA announced during a press telecon this morning the discovery of a fifth planet in the 55 Cancri system. This sets a new record for exoplanets in a […]

  • Armadillo Aerospace’s Latest Competition Attempt Fails

    With the moon visible overhead, Armadillo Aerospace unsuccessfully attempted to win the Northrop Grumman Lunar Lander Challenge at the Wirefly X PRIZE Cup this weekend at Holloman Air Force Base. The only competitor of nine ready to go for the event, Armadillo Aerospace, led by John Carmack of Doom and Quake fame, experienced both successes […]
