New space/astronomy webinar, USA to launch astronauts again, ISS, Comet Swan, AOP's Moon app, Shock at NASA, more


Hi all,

 

1. REGULAR FORTNIGHTLY SPACE and ASTRONOMY WEBINAR

After a very positive reaction to our first webinar on Mars, Nick Howes and I have been asked by Space Store Live to make it a regular fortnightly feature. It will be called "Space Store Live: Nick and Terry's Astro Round-up".

It will be approximately 30 minutes long, every second Tuesday, covering whatever is topical on space and astronomy. The next one will be on Tuesday 26 May, when we'll be mainly covering the forthcoming Crew Dragon launch to the ISS.

It's a Zoom webinar, and will be

Live streamed to YouTube SpaceStore Live! Channel and Live streamed to Facebook Live. I'll post any last minute news via Twitter.

2. USA to launch astronauts again, on May 27, @NASA will once again launch American astronauts on American rockets from American soil! With our @SpaceX partners, @Astro_Doug and @AstroBehnken will launch to the @Space_Station on the #CrewDragon spacecraft atop a Falcon 9 rocket. Let's #LaunchAmerica.

6. Personnel change at NASA   

Doug Loverro, NASA's chief of human spaceflight, resigned from his post on May 18 after less than a year on the job. Loverro's resignation as Associate Administrator for NASA's Human Exploration and Operations (HEO) Mission Directorate is a stunning development.

   Former NASA astronaut Ken Bowersox, has taken over HEO in an acting capacity and will therefore oversee Demo-2, the first crewed mission of SpaceX's Crew Dragon capsule. Demo-2, which will send NASA astronauts Bob Behnken and Doug Hurley to the International Space Station (ISS), is scheduled to lift off atop a SpaceX Falcon 9 rocket from Kennedy Space Center in Florida.

 

7. BCO Remote Learning.

Our Daily Astro Challenge: Weekdays at 12.30pm

   With this program we will slowly build your familiarity with the night sky through a series of increasingly complex challenges. These short, 2 minute episodes build on what you've learned in earlier sessions to take you from a novice to a real amateur astronomer in no time! These challenges have already proved to be immensely successful. You can view the back catalogue, and find new challenges every weekday. Check it out here.

    ESERO Ireland Remote Workshops For Tech Week: Wednesday/Thursday at 11am.

For those of you with children in primary school, we will be running live astronomy workshops next week that focus on the topic of Light Pollution. No materials needed, just a screen and an internet connection. We'll provide links to educational resources if you're interested in building on the learning experience yourself. Further details here.

 Planetarium at Home  Fridays from 4pm

We are particularly excited to be bringing our planetarium experience to a remote learning platform. Guided planetarium shows are at the heart of the BCO visitor experience and we're sure you'll enjoy watching these weekly shows as much as we enjoy making them. These are a perfect family weekend activity, with two short episodes dropping every Friday evening. These videos are also supplemented with ESERO Ireland Resources for those who want to go one step further with the learning experience. The first episodes dropped already!   We hope you find these programs are a good way to relax during this particularly stressful period, and that they can offer a stimulating educational activity for anyone with young people at home right now. We will have more programs coming online shortly.

 

8. Tim Peake's autobiography Signed copies of Tim Peake's autobiography ''Limitless'' due October, available for pre-order for £20 on Waterstone's site (unsigned would cost nearly as much).

 

9. Asteroid Day, 30 June UPDATE.  Asteroid Day was co-founded by astrophysicist and famed musician Dr. Brian May of  QUEEN; Apollo 9 Astronaut Rusty Schweickart; Filmmaker Grig Richters; and B612 President Danica Remy, to promote awareness and provide knowledge to the general public about the importance of asteroids in our solar system history, and the role they play in our solar system today. Events are scheduled leading up to 30 June, the date of the largest asteroid impact of Earth in recorded history (Tunguska).

The virtual festivities kick off with a full 34 days of Asteroid Day TV (ADTV) starting June 1st and running through July 4th. This year's ADTV will consist of asteroid-related content for all ages including academic  documentaries, family learning movies, current asteroid mission highlights, origins of the planet, and much more.

From June 30th, we'll be broadcasting a brand new Asteroid Day Live from Luxembourg. (ADLIVE)—a 4-hour program featuring astronauts, asteroid experts, and other notables.  Themes this year will include topics such as current missions advancing efforts to develop greater asteroid detection, tracking and deflection techniques, and space resource initiatives.

ADTV and ADLIVE Digital from Luxembourg will be available via SES signal on select local channels, online at Twitch TV, YouTube, and via the asteroidday.org. We'll be announcing details on how to tune in the last week of May.

 

10. International Astronomical Youth Camp in Spain, 12 July – 1 August

11. National Astronomy Week, 14 – 22 November.

 National Astronomy Week (NAW) will be held in the UK from Saturday 14 November to Sunday 22 November, to celebrate the close approach of Mars. Amateur and professional astronomers will be holding observing events during the week. Seen through a telescope magnifying about 100 times, Mars will appear as a pale orange disc, with its markings clearly visible, at a distance of 80 million km.

    Although Mars is at its closest to Earth a month earlier, by November it is well up in the sky during the early evening, allowing younger schoolchildren an opportunity to get a good view of the planet. It will not be as close again until 2033.  As well as Mars, Jupiter, Saturn and the Moon will be on show during National Astronomy Week. Details of observing events will be posted on the NAW website.

Webinar on Mars, ISS, Mercury + Venus, Comet Swan latest, Teaser, AOP Moon App, Int. Day of Light, USA's next human launch, more

Hi all,

 

1. Webinar on Mars today (Thursday 14 May) on Mars

I'll be taking part as a panel member in a Zoom webinar about the exploration of Mars today (Thursday) at 5.30 p.m. Arranged by the one and only Nick Howes, we'll attempt to answer all your questions about the past, present and future exploration of our fascinating red neighbour. It will last about an hour, and the Q&A session should start about 6.00  Join via  this webinar link to register directlyhttps://zoom.us/webinar/register/1115892260445/WN_hZaCQDCIQneMhgwRMkPxQQ. or via this Facebook event link. https://www.facebook.com/events/2538869296429098/

 

2. ISS visible through May.

The ISS began a new series of morning passes on 3 May, which will gradually transition into evening passes in the middle of the month, and these continue until May 29. during the transition period it's possible to see 4 passes during one night – some before midnight and the others after midnight. From Belfast, this is possible on the nights of 15-16; 16-17, and 17-18 May. . Full details for your location, and lots of other astronomy information, on the excellent free site www.heavens-above.com

 

3. Mercury will soon meet big sister Venus

Mercury is moving out and up into the evening twilight, and is already visible in good binoculars if you have good clear sky right down to the NW horizon. Look from about 30 minutes after local sunset.

   You'll get a great opportunity to spot it from 20 to 24 May, when it passes close to much brighter Venus. On the evening of 20 May Mercury lies 3º 15' below and right of Venus. Next evening it's only 1º 23' below Venus. On the 22nd it will have passed its brighter sister, and will lie 1º 21' to its left. By the 23rd it will lie just over 3º above left of Venus. And you might just spot a VERY thin crescent Moon, phase only 1.3%  lying 6º below Venus. Next evening will give a better photo opportunity, with the slightly brighter Moon lying to the left of Mercury, and Venus about 5º below right of Mercury.

    Observers in the S part of the island will get the best view, as the twilight will be less obtrusive.

 

4. Comet Swan may disappoint too?

https://www.msn.com/en-gb/money/technology/newfound-comet-swan-could-soon-fizzle-out-of-view/ar-BB13Zktz?ocid=spartandhp But all comets are inherently unpredictable in terms of brightness, so we'll just have to wait and see.

 

 5. TEASER

Still no takers for this one from Danny Collins

"On 14 August 1945, five days after they had dropped the second atomic bomb of WWII on Nagasaki, the US Air Force launched a B29 'Superfortress' bomber attack on Japan's last functioning oil refinery, on northern Honshu island, ostensibly to deny it to a possible USSR invasion of Japan. Japanese forces in Tokyo detected the approaching bombers, and fearing an attack on the capital, enforced an immediate blackout. This had the serendipitous effect of disrupting a revolt by extreme Japanese militants who were determined to prevent Emperor Hirohito signing the documents of surrender, and thereby saving hundreds of thousands of lives on both sides.

Bizarre as it may seem, there is a link between the particular B29 version used on that mission, and the demise of the dinosaurs some 65 million years ago. Happy hunting!!"

SPACE

https://www.msn.com/en-gb/news/spotlight/is-nasa-actually-working-on-a-warp-drive/ar-BB13ZM71?ocid=spartandhp Probably still just SF, but 'never say never'. One aspect not addressed is -how do you determine your arrival point? In other words just how much space do you 'warp' past the stationary spacecraft? In the analogy given, the tablecloth is of a fixed and arbitrary size: but it's all or nothing – it only works if you pull out the whole tablecloth.

   And where does the warped space go? If you were in another spacecraft just beside the active one what would happen to you? What would you see? According to the theory, the spacecraft itself does not move, so it should still be there beside you. Yet it would be in another part of the universe! (Now don't start quoting quantum theory at me – this is crazy enough as it is!)

ISS, Teasers answered, Starlink sky blight, Venus appulse, Int Day of light, USA to launch humans again, sky events, BCO remote learning, comet coming

Hi all,

 

1. ISS visible through May.

The ISS began a new series of morning passes on 3 May, which will gradually transition into evening passes in the middle of the month, and these continue until May 29. during the transition period it's possible to see 4 passes during one night – some before midnight and the others after midnight. From Belfast, this is possible on the nights of 15-16; 16-17, and 17-18 May. . Full details for your location, and lots of other astronomy information, on the excellent free site www.heavens-above.com

 

2.  Terry's Teaser, Two correct answers!  

A. Fairly Simple; . Which of the following constellation names is the odd one out, and why?

Canis Minor, Leo Minor, Ursa Minor?

   First correct answer was from Peter Millar, who correctly identified Leo Minor. It's the odd one out because there's no 'Leo Major' (just Leo), whereas we do have a Anis Major and an Ursa Major.

B. Challenging: What links the Latin word for heat, an English surveyor, a mountain in Greece, a Scottish physicist, and a simple type of eyepiece?

   Danny Collins came in fairly quickly with an answer which showed that at least he was ion the right track, though not correct. Then Andy McCrea came up with something similar, but still not correct

  Eventually Peter Millar (again!) got it.

Answer: they're the highest mountains on the inner solar system bodies,

Latin word for heat .gives Caloris Montes, highest mountain on Mercury (on rim of Caloris basin)

Scottish physicist – James Clerk Maxwell, = Maxwell Montes on Venus

English surveyor – George Everest, who survbeyed India, and after whom the mountain is named

A simple type of eyepiece = Huygenian, and Mons Huygens, highest mountain on the Moon,

A mountain in Greece = Mount Olympus, - Olympus Mons on Mars.

VERY well done to Peter and as he got both right, he'll get a prize at the next meeting – whenever that may be!

 

3. ANOTHER TEASER from Danny Collins

"On 14 August 1945, five days after they had dropped the second atomic bomb of WWII on Nagasaki, the US Air Force launched a B29 'Superfortress' bomber attack on Japan's last functioning oil refinery, on northern Honshu island, ostensibly to deny it to a possible USSR invasion of Japan. Japanese forces in Tokyo detected the approaching bombers, and fearing an attack on the capital, enforced an immediate blackout. This had the serendipitous effect of disrupting a revolt by extreme Japanese militants who were determined to prevent Emperor Hirohito signing the documents of surrender, and thereby saving hundreds of thousands of lives on both sides.

Bizarre as it may seem, there is a link between the particular B29 version used on that mission, and the demise of the dinosaurs some 65 million years ago. Happy hunting!!"

 

4. The impact of Low Earth Orbit satellites, including Starlink, on astronomy

They may be nice to look at, but they are vermin in the skies as far as optical astronomy is concerned.  I refuse to promote them in any way. A very important article by Jonathan McDowell, "The Low Earth Orbit Satellite Population and Impacts of the SpaceX Starlink Constellation" was published in ApJ 892, L36. You can read it here: https://arxiv.org/pdf/2003.07446

 

5. Watch Venus's appulse to Beta Tauri.

Venus continues its passage Eastwards across the sky relative to the stars, even as it sinks lower in the Western Twilight relative to the Sun. When the sky gets quite dark you'll see a fairly bright star above and to its left: that's Beta Tauri, aka Elnath (or Alnath), mag 1.7 representing the N horn of Taurus the Bull. Watch as Venus gradually approaches it, getting closest as we see it on the evenings of 10 and 11 May, when they will be less than 1.5 degrees apart (a bit less than 3 moon diameters). After that Venus starts (apparent) retrograde motion, as its faster motion on its inside orbit allows it to 'overtake' the Earth on the inside. It will then start to plunge ever more rapidly into the evening twilight, but not before it also has a nice conjunction with Mercury on 21 – 22 May. It will be beyond naked-eye visibility before the end of May.

 

6. International Day of Light, May 16.

This event also looks at the importance of Dark Skies. More details here https://www.lightday.org/events and for events see https://www.lightday.org/events

 

7. USA to launch astronauts again, on May 27, @NASA will once again launch American astronauts on American rockets from American soil! With our @SpaceX partners, @Astro_Doug and @AstroBehnken will launch to the @Space_Station on the #CrewDragon spacecraft atop a Falcon 9 rocket. Let's #LaunchAmerica

 

8. What's happening in the sky? An 8 minute video of what's coming up in the sky next week. See https://youtu.be/dDEXMxAAm_s Thanks to IAA webmaster Paul Evans for this.

 

9. BCO Remote Learning.

Our Daily Astro Challenge: Weekdays at 12.30pm

   With this program we will slowly build your familiarity with the night sky through a series of increasingly complex challenges. These short, 2 minute episodes build on what you've learned in earlier sessions to take you from a novice to a real amateur astronomer in no time! These challenges have already proved to be immensely successful. You can view the back catalogue, and find new challenges every weekday. Check it out here.

    ESERO Ireland Remote Workshops For Tech Week: Wednesday/Thursday at 11am.

For those of you with children in primary school, we will be running live astronomy workshops next week that focus on the topic of Light Pollution. No materials needed, just a screen and an internet connection. We'll provide links to educational resources if you're interested in building on the learning experience yourself. Further details here.

 Planetarium at Home  Fridays from 4pm

We are particularly excited to be bringing our planetarium experience to a remote learning platform. Guided planetarium shows are at the heart of the BCO visitor experience and we're sure you'll enjoy watching these weekly shows as much as we enjoy making them. These are a perfect family weekend activity, with two short episodes dropping every Friday evening. These videos are also supplemented with ESERO Ireland Resources for those who want to go one step further with the learning experience. The first episodes dropped already!   We hope you find these programs are a good way to relax during this particularly stressful period, and that they can offer a stimulating educational activity for anyone with young people at home right now. We will have more programs coming online shortly.

 

10. Another embarrassing error. EarthSky gets it wrong yet again. Very wrong. It's simply not true that a First Quarter Moon is high up at sunset as seen from anywhere on Earth. A FQ Moon in autumn is always low down in the sky at sunset from moderately high N latitudes.

   For example on 23 Sep 2020 the FQ Moon will be less than 11 degrees above the horizon at sunset from Belfast (Lat 54.6 degrees). And on 23 October it will be less that 10 degrees up at sunset. From Edinburgh, Scotland (Latitude 55.9 degrees) it will be even lower.

   This shows a fundamental lack of knowledge of basic astronomy. Appalling.

 

11. Tim Peake's autobiography Signed copies of Tim Peake's autobiography ''Limitless'' due October, available for pre-order for £20 on Waterstone's site (unsigned would cost nearly as much).

 

12. Star Trek Free Download There's a site ''toptvseries.org'' for slow free downloads of box sets, or fast download  if you pay. They're doing Star Trek Enterprise, they have all except TOS, and Next Generation.

(thanks to Derek Heatly for these last two)

 

13. COMET ATLAS may disappoint: - BUT

After early optimistic predictions, Comet ATLAS (C2019 Y4) is now breaking up and fading. You can get its position from www.heavens-above.com

See https://www.msn.com/en-ie/news/techandscience/newfound-comet-atlas-is-getting-really-bright-really-fast/ar-BB11vpNP?li=BBr5MK2

But latest reports indicate a tiny nucleus, which may soon disintegrate… - but

 

14 New Comet Swan is brightening and will soon be coming far enough North to be visible from Ireland. Unfortunately iot will be past its best by the timer we can see it well. Details also on www.heavens-above.com

 

15. New book on Soviet Space programme

Soviet Space Graphics: Cosmic Visions from the USSR (Thanks to Danny Collins for this)

 

16. Asteroid Day, 30 June.  Asteroid Day was co-founded by astrophysicist and famed musician Dr. Brian May of  QUEEN; Apollo 9 Astronaut Rusty Schweickart; Filmmaker Grig Richters; and B612 President Danica Remy, to promote awareness and provide knowledge to the general public about the importance of asteroids in our solar system history, and the role they play in our solar system today. Events are scheduled leading up to 30 June, the date of the largest asteroid impact of Earth in recorded history (Tunguska).

 

17. International Astronomical Youth Camp in Spain, 12 July – 1 August
The International Astronomical Youth Camp (IAYC) is a three-week long summer camp aiming to promote knowledge of astronomy and related sciences in a unique international atmosphere. The IAYC is an experience unlike any other; a place for unforgettable memories and lifelong friendships. During the camp, 65 young and enthusiastic participants from all corners of the world gather in a remote location in Spain to observe and learn about some of the most spectacular skies on this Earth. Applications for the 2020 camp are being accepted until 5 April 2020.
   International Astronomical Youth Camp, 12 July-1 August 2020;  Baños de Montemayor, Spain

18. National Astronomy Week, 14 – 22 November.

 National Astronomy Week (NAW) will be held in the UK from Saturday 14 November to Sunday 22 November, to celebrate the close approach of Mars. Amateur and professional astronomers will be holding observing events during the week. Seen through a telescope magnifying about 100 times, Mars will appear as a pale orange disc, with its markings clearly visible, at a distance of 80 million km.

    Although Mars is at its closest to Earth a month earlier, by November it is well up in the sky during the early evening, allowing younger schoolchildren an opportunity to get a good view of the planet. It will not be as close again until 2033.  As well as Mars, Jupiter, Saturn and the Moon will be on show during National Astronomy Week. Details of observing events will be posted on the NAW website.
