About Those Launch Cameras

Sat, 24 Feb 2018 10:37:17 +0000

Great video. Well done Curious Droid.



Hypervelocity Testing

Fri, 23 Feb 2018 04:43:33 +0000

The prospect of getting hit by debris is pretty scary. It would be great to be able to have something we could just hoover the debris – not as far fetched as it sounds.

SpaceX Launches PAZ – Replay

Thu, 22 Feb 2018 14:00:46 +0000

For those who were not able to watch the live SpaceX launch of the PAZ satellite here is a replay. There is about a 15 second lead-in time before the replay starts. Great launch and coverage.  Replays soon.  



ExoMars Trace Gas Orbiter

Thu, 22 Feb 2018 04:59:15 +0000

ESA put out a nice update on the ExoMars Mission. PLUS! There will be a SpaceX launch at 09:17 EST / 14:17 UTC. That’s IF all goes well. This launch was scrubbed yesterday due to winds. I will have a live link up at 14:00 UTC / 05:00 EST. The payload is the PAZ satellite.



The Flying Physicists

Wed, 21 Feb 2018 05:05:16 +0000

On this day, November 21, 1783, physicist Jean Francois Pilatre de Rozier, along with the Marquis d’Arlandes, became the first humans to fly. Story here – good stuff. Image via APS News (see link above)



Hubble’s View: PLCK G004.5-19.5

Wed, 21 Feb 2018 04:21:25 +0000

The name of this galaxy cluster is PLCK G004.5-19.5.  You may not think the name is very creative, but it did remind me of a paper:  Strong Lensing Analysis of PLCK G004.5-19.5, a Planck-Discovered Cluster Hosting a Radio Relic at z=0.52.  Thanks Hubble it was very useful. Heh, I remember the paper because of a […]



Martian Sunrise by Oppy

Tue, 20 Feb 2018 04:52:05 +0000

A few days ago I mentioned that the Mars Exploration Rover Opportunity (Oppy) is reaching another milestone, that of 5000 days on Mars and still returning science. Go Oppy!! The image above is the Sun rising on day 4,999 or 15 February, clicking the image should open a larger version in a new window. Here’s […]



Space Radiation on Earth

Mon, 19 Feb 2018 04:29:39 +0000

So from the Van Allen Belts we turn to cosmic rays. How do we study them? ESA is up to the task. I can’t wait until this is finished and returning data. Great stuff. Image: GSI Helmholtzzentrum für Schwerionenforschung GmbH/Jan Michael Hosan 2018 ESA – The constant ‘rain’ of radiation in space includes cosmic rays, which, […]



ESO’s Studentship Programme

Sun, 18 Feb 2018 12:24:18 +0000

Great opportunity! ESO — ESO’s Studentship programme provides a valuable opportunity for astronomers of the future to gain experience at the most productive ground-based astronomical observatory in the world. PhD students work alongside senior astronomers and engineers in a creative, collaborative and truly international environment, in which their careers are encouraged to blossom.



Fun and Games (and Physics)

What does one do for fun on the ISS? Have a look. Thanks to The World Science Festival
