Just three days away.
This is Friday’s press conference with Rosetta mission experts hosted by Emily Baldwin, ESA space science editor / Rosetta Blog
The video is in distinct segments of about 15 minutes and questions at the end.
Introduction and mission plans fellowed by Science at 15 minutes, Landing at 30 minutes and Summary at 45 followed by questions.
A teleconference discussing some of the science findings from the C/2013 A1 Siding Spring (aka: the Mars Comet) fly by of the planet Mars.
A bit technical here and there but very well explained and totally worth seeing.
BTW, it takes a few minutes to get going.
The participants were:
- Jim Green, director, Planetary Science Division, NASA Headquarters, Washington
- Nick Schneider, instrument lead for MAVEN’s Imaging Ultraviolet Spectrograph, University of Colorado, Boulder
- Mehdi Benna, instrument scientist for MAVEN’s Neutral Gas and Ion Mass Spectrometer, NASA Goddard Space Flight Center, Greenbelt, Maryland
- Don Gurnett, co-investigator on the Mars Advanced Radar for Subsurface and Ionosphere Sounding instrument on Mars Express, University of Iowa, Iowa City
- Alan Delamere, co-investigator for MRO’s HiRISE instrument, Delamere Support Services, Boulder, Colorado

Have a look at this Hubble image of Mars AND comet Siding Spring in the same field of view during the close pass on 19 October. The comet came as close as 140,000 km / 87,000 miles – only a third of our Earth to Moon distance. I am trying to imagine what that would be like.
This from Hubblesite:
This composite of NASA Hubble Space Telescope images captures the positions of comet Siding Spring and Mars in a never-before-seen close passage of a comet by the Red Planet, which happened at 2:28 p.m. EDT October 19, 2014. The comet passed by Mars at approximately 87,000 miles (about one-third of the distance between Earth and the Moon). At that time, the comet and Mars were approximately 149 million miles from Earth.
The comet image shown here is a composite of Hubble exposures taken between Oct. 18, 8:06 a.m. EDT to Oct. 19, 11:17 p.m. EDT. Hubble took a separate photograph of Mars at 10:37 p.m. EDT on Oct. 18.
The Mars and comet images have been added together to create a single picture to illustrate the angular separation, or distance, between the comet and Mars at closest approach. The separation is approximately 1.5 arc minutes, or one-twentieth of the angular diameter of the full Moon. The background starfield in this composite image is synthesized from ground-based telescope data provided by the Palomar Digital Sky Survey, which has been reprocessed to approximate Hubble’s resolution. The solid icy comet nucleus is too small to be resolved in the Hubble picture. The comet’s bright coma, a diffuse cloud of dust enshrouding the nucleus, and a dusty tail, are clearly visible.
This is a composite image because a single exposure of the stellar background, comet Siding Spring, and Mars would be problematic. Mars is actually 10,000 times brighter than the comet, and so could not be properly exposed to show detail in the Red Planet. The comet and Mars were also moving with respect to each other and so could not be imaged simultaneously in one exposure without one of the objects being motion blurred. Hubble had to be programmed to track on the comet and Mars separately in two different observations.
The images were taken with Hubble’s Wide Field Camera 3.
In just a few days Comet C/2013 A1 Siding Spring will make a close approach to the planet Mars.
Mark you calendars 19 October 2014 at 18:51 UTC.
The comet will come as close as 140,000 km /87,000 miles, that is only about a third of the distance to the moon. Can you just imagine what that would look like?
Earth is set to cross the debris path of comet 209P/LINEAR on 24 May 2014. No one knows quite what to expect. I’ll be finding out provided we have decent clouds.
The video suggests the best time is going to be around 0600 to 0800 UTC. If you are on the east coast of North America earlier in that range might be better because daybreak will be shortly after 0800 UTC.
How to find Camelopardalis? On the 24th (or any other time in the near future) you can find Camelopardalis by looking north. If the meteor shower is as busy as it could be, the location will be self evident. However, if there are only a few meteors or you just want to find it and have no idea, find the “Little Dipper” aka: Ursa Minor, and look from the dipper part down the “handle”, it points right to the area.
Still confused? Look above your northern horizon. Here’s a guide to help you out.
