What’s it sound like when you land on a comet? Well, as you would guess, it’s a “thud.” That’s the report from Martin Knapmeyer, a planetary scientist at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) A short but significant “thud” was heard by the Cometary Acoustic Surface Sounding Experiment (CASSE) as […]

NASA’s Mars Atmosphere and Volatile Evolution Mission (MAVEN) is off and running – starting its one-year primary science mission on November 16. “With the formal start of our science mission, we’re on track to be able to carry out our full mission as planned, and the science team is looking forward to an incredibly exciting […]

The NASA Office of Inspector General (OIG) issued a November 14 report that flags the space agency’s current and top management and performance challenges. Its key observation is that NASA’s “static” budgets, along with fiscal uncertainties, makes it tough for the space agency to move forward on its agenda. Looking forward to 2015, the NASA […]

Update – the Philae lander has entered sleep mode at 01:36 Central European Time (CET) on November 15, 2014. The Philae lander performed about 56 hours of continuous scientific measurements on the surface of Comet 67P. But by 01:15 CET on November 15 the energy state of the lander became so low that the engineers […]

Hush-hush spacecraft are providing new data on incoming objects within the Earth

Here’s new news via old data! Data gathered by U.S. government sensors onboard hush-hush spacecraft — and released to NASA for use by the science community — reveal that small impact events are frequent and random. A map of these small impact events – known as fireballs or bolides –has been released by NASA and […]

A new story from me, up today on Space.com: Innovative ‘Starshade’ Tech Could Illuminate Rocky Alien Planets by Leonard David, Space.com’s Space Insider Columnist November 14, 2014 06:56am ET http://www.space.com/27765-starshade-tech-alien-planet-search.html

This image was taken by the Philae comet lander looking down using its descent ROLIS imager when it was about 130 feet (40 meters) above the surface of Comet 67P/Churyumov-Gerasimenko.   It shows that the surface of the comet is covered by dust and debris ranging from mm to metre sizes. The large block in the top right corner is 5 meters in size. In the same corner the structure of the Philae landing gear is visible.   The aim of the ROLIS experiment is to study the texture and microstructure of the comet

The European Rosetta mission deposited the Philae lander onto comet Comet 67P/Churyumov–Gerasimenko on November 12, Central European Time. European space scientists confirmed that the probe bounced three times prior to coming to a stand-still attitude. Harpoons on the lander did not fire and Philae appeared to be rotating after the first touchdown, which indicated that […]

Europe’s Rosetta spacecraft deployed the Philae lander – achieving a space first. They have been riding through space together for more than 10 years. Philae is the first probe to land on a comet, while Rosetta is the first to rendezvous with a comet and follow it around the Sun. The information collected by Philae at one […]
