Mars Curiosity Rover fell into a safe mode on 16 March as result of on board data file size anomaly. A file meant for deletion was connected to active command file and the safe-mode entry was triggered when the command file failed a size-check by the rover’s protective software. The system the rover’s computer system was rebooted and recovered on 19 March.

After NASA found it could no longer offer launches for the ExoMars mission, the European Space Agency (ESA) approached Russia for help. As a result of long running discussions, on 14 March the ESA Director General Jean-Jacques Dordain and Head of Roscosmos Vladimir Popovkin have signed a formal agreement for their respective agencies to work in partnership on the ExoMars programme towards the launch of two missions: one to be launched in January 2016, and one to be launched in 2018.
Two major comets are due to become visible this year to sky-watchers – clear skies permitting. The first has now disappeared from view from the Southern Hemisphere, but while viewers there have lost out, “northerners” have gained as Comet Pan-STARRS has now become visible to the naked eye from the Northern Hemisphere. To see it, look near the crescent Moon in the Western sky after sunset. The comet will rise further in the sky as the month of March wears on and should become more visible despite starting to move away from the Sun after its perihelion closest approach. The comet’s tail(s) should be able to be easily seen with binoculars.
The mystery change in the orbital parameters of a small Russian satellite have now have been explained: it was apparently caused by a debris strike and the debris came from a Chinese anti-satelltie missile test. On 4 February, the Russian Institute for Precision Instrumenet Engineering reported that the 7.5kg BLITS (Ball Lens In The Space) passive laser reflector nanosatellite had had significantly changes to elements of its Sun-synchronous near-polar orbit, to its spin velocity and in is attitude and may have split into two tracked objects. It was only after analysis by the Centre for Space Standards and Innovation that the change was traced to a debris strike which occured on 22 January 2013. There remains doubt however about why the BLITS spacecraft only split into two parts rather than several pieces which is more usual after such a collision while other sources suggest that no collision occured.
According to NASA, there is a chance that the newly discovered comet, Comet 2013 A1 (Siding Spring), could strike the planet Mars on 19 October 2014. Original estimates of trajectory of the comet generated by the Near-Earth Object (NEO) Program Office at NASA’s Jet Propulsion Laboratory in Pasadena indicated that the comet would pass within 186,000 miles (300,000 kilometers) of Mars. However, the latest trajectory estmates now have it passing about 31,000 miles (50,000 kilometers) from the Red Planet’s surface and NASA does not rule out the possibility of a strike. Rob McNaught discovered this new comet on 3 Jan 2013, at Siding Spring Observatory in Australia.
On a lighter note: Round the planet Mars flight plan detailed by Dennis Tito but couple will have to get on
Denis Tito and his Inspiration Mars outfit has been giving full details of their plan to send humans around the planet Mars including using a capsule and inflatable living area. The full story is here.
A film sequence of radar images of asteroid 2012 DA14 during its close pass of Earth on 15 February has been released by NASA. The imagers were obtained using the 70m diameter Deep Space Network antenna at Goldstone, California as the 4m long asteroid moved away from the Earth. Each of the 72 frames required 320 seconds of data collection by the Goldstone radar. The images have been looped nine times for the video and clearly show the object was rotating. The resolution is only 4m per pixel.
As the world waited for an expected close pass of an asteroid 2012 DA 14 on the evening of 15 February, a second smaller object, fell onto the Ural mountains in Central Russia on the morning of that day. At 0315 GMT a 15m diameter meteorite plunged through the atmosphere explosively breaking up as it did so at a height of circa 20-25km and with an explosive power of 500kT (kiloton equivalent of TNT). The shockwave resulting from the air burst explosion was reported to have injured more than one thousand people as it blew out windows and damaged roofs in the city of Chelyabinsk. The injuries were mainly minor and no fatalities were reported.
Truth is stranger than fiction: after horsemeat scandal will Soylent Green science fiction plot be next? (Updated)
While the disclosure by the first taikonaut (Chinese astronaut) Yang Liwei that he had eaten dog while on China’s first manned orbital spaceflight mission Shenzhou 5 in 2003, made some dog lovers in the West wince, many in the Anglo-Saxon culture hold a similar revulsion for the eating of horsemeat. Thus, in the worse food scandal since the “mad-cow prion” contamination of British beef during the late 1980s, there has been collective shock at the disclosure that minced horsemeat is now in the British (and European) food supply. The scandal came to light as DNA tests found that some “minced beef” products had a 100%.horsemeat content leading some to worry if there may now be worse to come.
A Near Earth Object (NEO) asteroid 2012 DA14 is due to make a very close pass of Earth on 15 February as it flies well within the Geostationary Orbital altitude of 36,000km at circa 1800-2200 GMT. Observers in Europe wanting to view the object should see it moving across Ursa Major (aka Great Bear, Big Dipper, Plough) constellation from 2100 GMT onwards.
