Lecture, Soyuz in Belfast, Venus & Mars, Space week, ISS, Close PHA , New events


Hi all,
 
1. NEXT IAA LECTURE,  Wed 4 October, 7.30 p.m"Cloudy with a chance of flares: the importance of space weather forecasting". By Dr Sophie Murray of TCD. Dr Murray is an expert on 'space weather', which is the weather in and surrounding the Sun and how it affects the planets, especially planet Earth. And in addition, she also worked for a year at the Met Office in England, so she has a terrestrial meteorologist's expertise on space weather.
   Space weather is being recognised as being of great importance for our planet, as it affects everything from our own climate to our modern communications systems, astronauts and space-based equipment, air travel, and our electricity infrastructure.
   This will be a fascinating lecture, delivered by an eloquent expert on both aspects of the subject
Wed 4 October 7.30 p.m., Bell Lecture Theatre, Physics Building, QUB. Free admission.  Free parking on QUB campus after 5.30 p.m.
N.B. This will be the IAA's event to mark 'SPACE WEEK'
 
2. NEW: BREAKING NEWS - Tim Peake's Soyuz spacecraft will be coming to Belfast! The Soyuz spacecraft which brought Tim Peake back to Earth will be coming to Belfast this autumn. More details later - watch this space!
 
3. NEW: Venus, the brilliant Morning Star, will pass close by Mars.  Venus is still well-placed in the dawn sky for the next few weeks. Watch as it approaches much fainter Mars over the next few mornings.
On 1 October Venus will be 2 deg 40' (about 5 Moon diameters) above right of Mars. On subsequent mornings that separation will shrink to 2 deg 6'; 1 deg 30; 56' (i.e. just under 1 deg), while by the morning of 5 Oct Venus will lie only 21' above Mars - that's about 2/3 of a Moon diameter. Next morning (6th) Venus will lie just 22' left of, and a bit below Mars, and the separation will then continue to increase as Venus moves in towards the Sun.
   Of course this is just a line of sight effect, as Mars lies much further away than Venus.

6. SPACE WEEK at BCO
SPACE WEEK: Our Planet  - Our Space - Our Time
Space Week is Ireland's national STEM week in parallel with World Space Week. It is YOUR week to focus on the wonders and realities of the Universe around us.
Taking place from October 4 – 10,2017, Space Week will enable all people to explore how, as 21st century citizens under one sky, we can use the power of critical thinking, science, technology, engineering and maths to shape our understanding of life on Earth and our place in Space.
   Plan an event: Organise an event in your school or community and register your details on www.spaceweek.ie. All registered events will receive Space Week merchandise and promotional materials.
   Attend an event: Family-friendly events, stargazing, workshops and more will take place nationwide.  Or discover the Universe in your own home using the fun space activities on spaceweek.ie 
  Discover Your Universe! Find or register events on spaceweek.ie #SpaceWeek16

9. NEW: Potentially Hazardous Asteroid 2012 TC4 will make a close pass to Earth on 12 October. Astronomers are certain that it will not come any closer than 4,200 miles (but that's damn close!), but is more likely to be about 27,000 miles at its closest; Even so, that's just outside the orbit of the geosynchronous satellites. More details later as they become available.
 
10. NEW: Public Lecture, Armagh Observatory and Planetarium, 13 October, 7 p.m.

http://www.dailymail.co.uk/sciencetech/article-4906154/Europe-withdrawal-asteroid-mission-branded-catastrophe.html Why oh why do they have such ridiculous illustrations? (1) Asteroids do not trail smoke in space! (2) The one illustrated is about 1,000 miles in diameter - bigger than any known asteroid, and none of the biggest 100 asteroids are going to hit Earth in the next million years. (3) There would be not the slightest hope of deflecting one this size. (4) If one anywhere near that size was to hit Earth, it would be the end of ALL life on Earth. But as already noted, that won't happen.
http://www.dailymail.co.uk/sciencetech/article-4909372/Children-born-moon-decades.html You'd think that ESA should know better than to show lots of detail in brightly lit areas which are actually in shadow, and should therefore be inky-black - see the second and third illustrations! Back to Space School for whoever approved those!

http://www.huffingtonpost.co.uk/entry/team-emerge-after-spending-eight-months-living-on-mars_uk_59bfd097e4b02da0e1438e6b That's a start, but there's also the little matter of having to spend another 6-8 months in a cramped spacecraft before they even get to Mars, and another 6-8 months coming back again!
http://www.dailymail.co.uk/sciencetech/article-4925958/Dubai-announces-plans-build-100m-simulation-Mars.html Somewhere in the high cold deserts of S. America would be more realistic!
http://www.dailymail.co.uk/sciencetech/article-4931320/Lockheed-Martin-reveals-plan-2028-Mars-base-camp.html There are several major drawbacks to this concept.
1. Since they won't land on Mars (except for possible short visits) they will be weightless for the whole of the 1,000 days - that will cause severe physiological degeneration. They should rotate at least part of the ship, to create some artificial gravity. And if they were to have a surface base on Mars instead, they would have 38% of Earth gravity for 8 months, which is a heck of a lot better than none.
2. They will be exposed to cosmic and solar radiation for the whole of the 1,000 days, although they will get brief periods of shielding from solar radiation only, when they pass behind Mars on each orbit. If they landed on Mars for the eight months they will be there, they could get shielding from both forms of radiation by building a suitable shielded habitation module, or by living in lava tubes. There is no mention of radiation shielding in the design of the ship.
3. By staying in the ship for almost all of the 1,000 days they will increase the psychological pressures from living together in such close quarters. - By going onto the surface for eight months or so, there would be a change of habitat, and the opportunity for much more EVA activity.
