  1. Yes, ... I agree with you .... astronomer scientists are finding certain Martian clouds hard to explain it seems. This from Nature Feb 2015 ... from an observation from @ 2012. https://www.nature.com/news/martian-mystery-cloud-defies-explanation-1.16924 This elongated trail, which I read was explained away as formed by temperature differential of rising air over the peak of the ‘extinct’ volcano creating a vapour trail cloud. Hmmm ... wouldn’t we have been seeing these all the time ? ... instead of once in a blue moon? Unusual it sustained so long over such a long distance - as you mentioned. Something clearly doesn’t fit in the Theory about the nature/composition of the Martian atmosphere, rate of sublimation if these clouds are formed by water vapour or floating ice crystals as some have proposed. (snow clouds?! - on Mars ... surely not?) This article from New Scientist talks about frozen carbon dioxide and solar bursts/burps(?) as a long shot explanation for general ‘clouds’ seen: https://www.newscientist.com/article/2086907-unexplained-plume-over-mars-could-be-caused-by-solar-outburst/ - but most can’t see a solar burst triggering a narrow trail like this.
  2. Remember this vapour plume on Mars? No eruption that time either unfortunately. There is seismic activity ... so possibly one day Mars might reawaken??
  3. Hi SGL Photographers ... just bumped into this ... on Youtube .... recordings of the earliest films ever made .... No. 1 is ‘Passage de Venus’ dated as 1874. Thought some might be interested. Transit across Sun (cut v.short I’m afraid to say) ..... It starts just 0.39 seconds into this clip. There appears to be a rather odd bubble bulge on the right hand side of the planet .... I thought it might be a film surface artefact, or a lensing effect at first ... but I noticed it appears to be ‘glued to the Planet’ as it transits?? A bit odd. Can anyone explain what it might be? Here’s a long shot suggestion if the planet had a ‘pimple’ back then .... remember the large plume on Jupiter’s moon, Io? ....spraying into space creating an optical ‘bulge effect’ at a distance. Possibly a serious surface emission event happening on Venus at that time? As I said, ... a long shot! Guess Venus Transit stills taken by astronomers in 1874 which are lodged in an Archive somewhere will confirm if it’s some sort of ‘photographic distortion’? - A bit weird. Can anyone give advice on this? The Io example.
  4. Is it possible the data/calculations making up the computer model simulation are erroneous... rather than there being some unknown factor interfering with the observation?
  5. Equipment: Eyes, binoculars, amateur enthusiasm, the Internet, inquisitive open mind.

  6. Maybe the cause of lensing effects aren’t solely gravitational? Chemicals, liquids between a light source can cause distortions Imagine some mechanism out in space generating such pockets of refraction? Aren’t our observations ‘lensing’ through the ice fields of the Kuiper Belt?
  7. As suggested in my thread “Is Mars teeming with life?” ... do you think the dark deposits around many Martian geysers are supporting the growth of primitive bacteria, Ouroborus? Should we be too concerned about contaminating these relatively dead planets we are visiting? Seeding them with new lifeforms that might make them develop a more significant atmosphere - turn a hostile planet into something a bit more hospitable to humans? .... surely that’s not a bad idea, is it? Let’s speculate that highly advanced extra-terrestrial civilisations could have ‘seeded’ Earth to become the Eden of today ... maybe we can return the ‘gesture’ and develop genetically modified primitive lifeforms that might survive the extremes of the current Martian climate.
  8. Is anyone else surprised by the degree of damage sustained by the Rover vehicle’s wheels shown in this article? Looking at pictures of new rovers under test ... it appears the wheels are now being made from specialised plastics - less likely to be denatured by corrosive elements.
  9. Sorry to be pessimistic, but no sensible intelligent person sees any ‘profit’ or ‘quality of life’ putting themselves on such an inhospitable piece of solar driftwood like Mars ... These environments barely sustain a working robotic machine for 15 years. Just walk into any desert region on Earth and see countless examples where human colonisation has failed - in an atmosphere/environment far more conducive to supporting organic/human life - Colony failure even though human support + resources were easy to ship in from barely a few miles away ... The novelty and ‘pleasure’ of Colonising Mars will wear off long before they grow their first sustainable vegetable. Duped Colonialists will soon realise they signed up and won a one-way ticket to live in a ‘potentially stir-crazy Hellhole’. Only ‘kamikaze’ scientists with no friends/family/affection for Planet Earth - would volunteer for a Project NASA might be forced to cancel when a new President took office! The cost to sustain a Martian Colony to survive, at such a distance from our Earth is astronomical - and a complete waste of money - because promises of huge mineral wealth from Mars are just a pipe dream that will NEVER deliver payback. What most realists see here is just glossy speculative sci-fi videos/articles that make Colonisation look easy - PR designed to suck in gullible ‘Prospectors/Investors’ .... possibly dupe the public tax-payers to fund yet another Fool’s Gold project with no hope of a ‘return’.... Cern Mk2!? .... it’s all very interesting ... but like the Dragon’s Den ... tax-payers should never be investing - Very little return. The Public doesn’t mind globalists like Elon Musk/Bezos/Branson etc spending their own money - on their ‘space vanity projects’ - that will invariably never pay investors back. Even if the Rover vehicle had discovered Mars was made of Cocaine - with gold bars/cut diamonds stacked up ready to ship at the Mars 1 Bezos Interplanetary SpacePort ... the logistics and costs of shipping all those treasures to Earth, back into the safe hands of investors, would be so enormous ... Profit would be pretty much = Zero £/$ [If the tax-payer found out where their ‘investment’ was landing - the rush to collect their ‘returns’ could cause chaos ... and if a cargo spaceship crashes in my back garden .... nobody but me will be shovelling the ‘snow’ off MY roof] If globalists/scientists want to play at ‘Space Colonisation and Interplanetary Mining’ ... surely they should spend the next 500 years practicing and perfecting that on the Moon first?? - before biting off more than they can chew trying to do it on inhospitable planets like Mars, surely 500x harder to survive on ... and hardly in the backyard.
  10. Doing some amateur browsing of Google Mars a while back, the black staining of the geyser plumes near the South Pole caught my attention. Recently I toyed with the idea the staining might be coloured by algae/bacterias. FeS munching variety? This research also jumped out from the Search engine - thought it worth sharing. https://www.researchgate.net/profile/Rhawn_Joseph2/publication/319722029_Contamination_and_Damage_to_the_Mars_Rovers_by_Martian_Fungi_and_Bacteria/links/59baf5efa6fdcca8e55de935/Contamination-and-Damage-to-the-Mars-Rovers-by-Martian-Fungi-and-Bacteria.pdf?origin=publication_detail Anyone got any other details/evidence to confirm these findings? + possibly expand on them?
  11. Er ... Yes, ... and Earth scientist's Periodic Table might not be the same as Extra-terrestrial scientist's Periodic Tables elsewhere in the possible Universe ... ahem. Our discovery of the Universe is in it's infancy, right?? .... also our knowledge regarding Panspermia ... so wise to keep an open mind I guess?!
  12. Bearing in mind how wobbly some of the subsurface radar trace results have been on some of these archaeological programmes (eg: Time Team surveys seemed to throw up features galore on trace maps …. but the Team mostly found little when they dug below the surface) Let's hope these instruments are more accurate! Do you think there is any way that mild seismic activity on areas of Mars/ancient volcanic springs/ +geysers in the South could be slightly warming the liquid of these 3 subterranean lakes and changing the signature - maybe giving the impression it was brine? …. With this area shrinking and sublimating rapidly, maybe Life Scientists need to be encouraged to rush to this area a bit quicker? - Be nice if these lakes were less salty - to increase the prospects there being a greater variety of microbes swimming around in them. Maybe around each extinct volcano there are lava tubes of condensed water containing more primitive life forms knocking out those pockets of Methane!? No harm in speculating, throwing ideas around - just for fun … until manned missions/remote drone probes confirm one way or another. Who knows - maybe those suspiciously dark plumes and spider staining of the sands around geysers in the South are a mixture of oozing ancient volcanic spring water through surface cracking/tectonics and primitive algaes clinging to survival as the liquid sublimates ...similar to those algaes on Earth??
  13. Thanks for that nugget, Markse68 - Wikipedia seems to confirm a CO2/water mix … Main article: Martian polar ice caps North polar early summer water ice cap (1999); a seasonal layer of carbon dioxide ice forms in winter and disappears in summer. South polar midsummer ice cap (2000); the south cap has a permanent carbon dioxide ice cap mixed with water ice.[128] Mars has two permanent polar ice caps. During a pole's winter, it lies in continuous darkness, chilling the surface and causing the deposition of 25–30% of the atmosphere into slabs of CO2 ice (dry ice).[129] When the poles are again exposed to sunlight, the frozen CO2 sublimes. These seasonal actions transport large amounts of dust and water vapor, giving rise to Earth-like frost and large cirrus clouds. Clouds of water-ice were photographed by the Opportunity rover in 2004.[130] The caps at both poles consist primarily (70%) of water ice. Frozen carbon dioxide accumulates as a comparatively thin layer about one metre thick on the north cap in the northern winter only, whereas the south cap has a permanent dry ice cover about eight metres thick. This permanent dry ice cover at the south pole is peppered by flat floored, shallow, roughly circular pits, which repeat imaging shows are expanding by meters per year; this suggests that the permanent CO2 cover over the south pole water ice is degrading over time.[131] The northern polar cap has a diameter of about 1,000 kilometres (620 mi) during the northern Mars summer,[132] and contains about 1.6 million cubic kilometres (5.7×1016 cu ft) of ice, which, if spread evenly on the cap, would be 2 kilometres (1.2 mi) thick.[133] (This compares to a volume of 2.85 million cubic kilometres (1.01×1017 cu ft) for the Greenland ice sheet.) The southern polar cap has a diameter of 350 kilometres (220 mi) and a thickness of 3 kilometres (1.9 mi).[134] The total volume of ice in the south polar cap plus the adjacent layered deposits has been estimated at 1.6 million cubic km.[135] Both polar caps show spiral troughs, which recent analysis of SHARAD ice penetrating radar has shown are a result of katabatic winds that spiral due to the Coriolis Effect.[136][137] The seasonal frosting of areas near the southern ice cap results in the formation of transparent 1-metre-thick slabs of dry ice above the ground. With the arrival of spring, sunlight warms the subsurface and pressure from subliming CO2 builds up under a slab, elevating and ultimately rupturing it. This leads to geyser-like eruptions of CO2 gas mixed with dark basaltic sand or dust. This process is rapid, observed happening in the space of a few days, weeks or months, a rate of change rather unusual in geology – especially for Mars. The gas rushing underneath a slab to the site of a geyser carves a spiderweb-like pattern of radial channels under the ice, the process being the inverted equivalent of an erosion network formed by water draining through a single plughole. Throwing ideas around - wonder if the high velocity vortex winds of Mars are sinkholing layers of supercooled C02 and traces of water vapour at the Poles as a fairly thin layer periodically? Guessing these points (Wiki) below might also be causing the rapid Southern Pole shrinkage effect at times when a number of factors coalesce: The comparatively large eccentricity of the Martian orbit has a significant effect. Mars is near perihelion when it is summer in the southern hemisphere and winter in the north, and near aphelion when it is winter in the southern hemisphere and summer in the north. As a result, the seasons in the southern hemisphere are more extreme and the seasons in the northern are milder than would otherwise be the case. The summer temperatures in the south can be warmer than the equivalent summer temperatures in the north by up to 30 °C (54 °F).[189] Mars has the largest dust storms in the Solar System, reaching speeds of over 160 km/h (100 mph). These can vary from a storm over a small area, to gigantic storms that cover the entire planet. They tend to occur when Mars is closest to the Sun, and have been shown to increase the global temperature.[190] Wonder if this didn't help either preserving the Southern cap?: In September 2017, NASA reported radiation levels on the surface of the planet Mars were temporarily doubled, and were associated with an aurora 25 times brighter than any observed earlier, due to a massive, and unexpected, solar storm in the middle of the month. and: Mars has the largest dust storms in the Solar System, reaching speeds of over 160 km/h (100 mph). These can vary from a storm over a small area, to gigantic storms that cover the entire planet. They tend to occur when Mars is closest to the Sun, and have been shown to increase the global temperature. The storms of 2012+2018 being significantly large to upset things I guess?
  14. https://www.republicworld.com/technology-news/science/scientists-find-network-of-buried-salty-lakes-beneath-mars-surface.html In this article, johnturley … there are a couple of pictures of the Martian South Pole …. The Mars Global Surveyor picture(date??) shows a significant area of surface coverage which you would probably be able to see from Earth in your observations. However, the Mars Express picture (2018) shows an alarming shrinkage in the cap. I guess there could be seasonal variations which might explain some of the shrinkage …. depending on time of year respective photos were taken. It's a concern to those seeking Life on Mars that some Southern polar lakes might have evaporated away relatively recently … wonder if there are primitive lifeforms lying on the surface near recently exposed dried lake beds? Definitely an area worth exploring for the Life Scientists.
