Sketch of Astronomer Heather Couper

December 3, 2022

This is quite an obscure one, but I’ve drawn her because she was an important pioneer and science populariser in her way.

The Wikipedia page on her begins with this potted introduction to her life

Heather Anita CouperCBE FInstP FRAS[1] (2 June 1949 – 19 February 2020) was a British astronomer, broadcaster and science populariser.

After studying astrophysics at the University of Leicester and researching clusters of galaxies at Oxford University, Couper was appointed senior planetarium lecturer at the Royal Observatory, Greenwich. She subsequently hosted two series on Channel 4 television – The Planets and The Stars – as well as making many TV guest appearances. On radio, Couper presented the award-winning programme Britain’s Space Race as well as the 30-part series Cosmic Quest for BBC Radio 4. Couper served as President of the British Astronomical Association from 1984 to 1986, and was Astronomy Professor in perpetuity at Gresham College, London. She served on the Millennium Commission, for which she was appointed a CBE in 2007. Asteroid 3922 Heather is named in her honour.[2]

The online encyclopedia states that she was encouraged in her career after writing a letter to Patrick Moore about it when she was 16. He replied, ‘Being a girl is no problem’. She studied astronomy and physics at Leicester University in 1973, where she met her long-term collaborator, fellow astronomy student Nigel Henbest. The two formed a working partnership, Hencoup enterprises, devoted to popularising astronomy. She then carried out postgraduate research as a student of Linacre College, Oxford, in the university’s Astrophysics department. She became the senior lecturer at the Caird Planetarium at Greenwich. In 1984 she was elected president of the British Astronomical Association. She was the first female president and second youngest. I can remember her appearing on Wogan and playing down the fact that she was the first woman to become president, far preferring to be noted as the youngest. She also served as the President of the Junior Astronomical Society, now the Society for Popular Astronomy. In 1988 the London Planetarium invited her to write and present its major new show, Starburst. In 1993 she was appointed professor of astronomy at Gresham college. She was the first woman to hold the position in 400 years and remained professor until her death.

She wrote and co-wrote with Henbest over 40 books, as well as writing articles for a range of magazines such as BBC Sky at Night, BBC Focus and Astronomy. She also presented a lecture on the solar eclipse in Guernsey in 1999, and led expedition to view other eclipses in Sumatra, Hawaii, Aruba, Egypt, China and Tahiti. She also made numerous public appearances and talks about the cruise liners Arcadia, Queen Mary 2, and Queen Victoria. She was aboard Concorde when it made its first flight from London to Auckland. She also appeared and spoke at various science festivals, including Brighton, Cheltenham, and Oxford. She also spoke at corporate events for British Gas, Axa Sun Life and IBM.

She also presented a number of programmes and series on astronomy on the radio. These included Starwatch and The Modern Magi on Radio 4. She also presented an Archive Hour programme on the same channel on Britain’s Space Race, for which she received an Arthur C. Clarke award. She also appeared on Radio 2, and Radio 5Live, as well as making other appearances on Radio 4. She also presented a series of thirty 15-minute episodes on the history of astronomy. Her shows for the BBC World Service included A Brief History of Infinity, The Essential Guide to the 21st Century, and Seeing Stars, which was co-hosted by Henbest.

She made frequent appearances as the guest expert on various TV programmes, mostly on Channel 4. She made her first TV appearance on The Sky at Night, In 1981 she presented the children’s TV programme, Heaven’s Above, on ITV with Terence Murtagh. I think I remember watching this when I was about 14 or so. She then presented the series The Planets for Channel 4, which was followed by The Stars. She also presented the ITV show Neptune Encounter, the Horizon episode ‘A Close Encounter of the Second Kind’, and Stephen Hawking: A Profile on BBC 4.

Couper, Henbest and the director of her series, The Stars, founded a production company, Pioneer Productions. The Neptune Encounter, which covered Voyager 2’s flyby of the planet, was its first programme. She was also the producer for the Channel 4 shows Black Holes, Electric Skies and Beyond the Millennium. She later left the company to concentrate on more general radio and TV appearances.

In 1993 she was appointed a member of the Millennium Commission. Of the nine commissioners appointed, only she and Michael Heseltine continued until it was wound up.

Outside her work on astronomy, she was also a guest presenter on Woman’s Hour, as well as the John Dunn programme and Start the Week on the radio. She was also interested in local history and literature, and so appeared on Radio 4’s With Great Pleasure and Down Your Way. She also appeared on Radio 3’s In Tune selecting her ‘pick of the proms.’ She was also the narrator on a number of other factual programmes, including Channel 4’s Ekranoplan: The Caspian Sea Monster, and Raging Planet on the Discovery Channel.

So, a huge science populariser, but probably one whose achievements are obscured by other, more prominent, celebrities.

As well as the children’s astronomy programme, I also once saw her speaking on about Mars and the question of life on the Red Planet at the Cheltenham Festival of Science. She had a rather mischievous sense of humour. There’s a real possibility that life in some form has existed on Mars and may exist now, but if it does, it’s almost certainly at the level of microbes. At the time, however, various individuals who had spent too long looking at photos of the planet claimed to have seen much larger lifeforms on the planet. There was a programme on Channel 4 in which a Hungarian astronomer appeared to describe how he believed there were massive mushrooms growing there. People also thought the saw giant ‘sand whales’ crawling about its surface, like the sandworms in Dune. These were, in fact, geological features left by some of the dune’s slumping, which created a trail that looked like the segmented body of a worm. One of the peeps taken in by this was the late Arthur C. Clarke. Clarke rang her up from Sri Lanka, asking her if she’d seen them and telling her that he really didn’t know what to make of it. She commented that for a moment she thought he’d gone mad, then covered her mouth like a naughty child caught saying something she shouldn’t.

For all that she played down her importance as a female pioneer in astronomy, I think she did prepare the say for more women to enter it and become television presenters. There’s now a drive for more women in the hard sciences, and we’ve science had a Black woman presenter, Aderin-Pocock, on the Sky At Night, and female astrophysicists and mathematicians appearing on the radio and TV.

Terraforming the Moon by Comet

December 31, 2016

In my last blog post, I discussed the passed in David A. Hardy’s book, Atlas of the Solar System, in which he described the possible methods which might be used in the future to transform Mercury, Venus, the Moon and Mars into worlds, where humans and other creatures could live in the open, instead of the enclosed environments they need now to protect them from the harsh conditions of space. In the case of Venus, comets would be used to increase the planet’s rotation from its current 224 Earth days to a terrestrial day, and give the planet water. Looking through YouTube, I found this video by Fraser Cain, in which he talks about using the same method to terraform the Moon, as suggested by the space scientist and SF writer, Gregory Benford. This is part of a series of videos on space and space colonisation. At the beginning of the video, he mentions a previous one about the terraforming of Venus.

The explanatory section on the YouTube page provides this transcript of his talk.

In our episode about terraforming Venus, we talked about cooling the planet with a giant sunshade, and then hand-wavingly bind up all that carbon dioxide.

We did the same with Mars, filling the atmosphere with greenhouse gasses to warm it up, and releasing the planet’s vast stores of C02 to thicken the atmosphere. Then just crash in a few comets worth of water and upgrade them to to a 3 star resort.

We’re pitching this as a new series on the Discovery Network, called “Flip My Planet – Canada”.

Now let’s turn our imagination towards another rockball that is really more of a fixer-upper: The Moon. I know, you never even thought of the Moon as a place that we could possibly terra-renovate. Go ahead and imagine with me all the possibilities of a verdant green and blue little world hanging in the night sky. Doesn’t that sound great?

So, what does it take? Do we tear it down and just use the orbital lot space? Should we raise it up and lay a new foundation? Or could we get away with a few coats of paint and adding an atrium on the backside?

Fortunately for me, scientist and sci-fi author Gregory “Planetary Makeover” Benford has already done the math.

Let’s take a look at what we’d need to get the Moon habitable. For starters, the fact that the Moon is so close to Earth is a huge advantage. This is like living on the same block as a Home Depot, and we won’t have to travel far to get supplies and equipment to and from our project.

We’re going to need an atmosphere thick enough to breathe and trap in the Sun’s heat. This takes wild comet capture and harvest, tear them apart and smash them into the Moon.

Benford notes that you probably want be careful not to let an entire comet collide with the Moon because it might spray your primary investment home with debris and do a little damage to the resale value, or potentially annoy your tenants.

This could get bad enough that we’d have to terraform Earth to get it livable again, and you’d need to bring in Mike Holmes to publicly shame us and put our primary residence back in order.

After you’d splattered a few comets on the Moon, it would have an atmosphere almost immediately. The transfer of momentum from the comet chunks would get the Moon rotating more rapidly.

If you invest a little more in your planning stage, you could get the Moon spinning once every 24 hours, and even tilt its axis to get seasons. Benford estimates that we’d need 100 Halley’s mass comets to get the job done. This might sound like a pretty tall order, but it’s tiny compared to number of comets we’d need for your Mars or Venus real estate scheme.

The maintenance and upkeep isn’t going to be without its challenges. Low gravity on the Moon means that it can’t hold onto its atmosphere for longer than a few thousand years.

Once you got the process going, you’d need to be constantly replenishing our your orbital cottage with fresh atmosphere. Fortunately, we’ve got a whole Solar System’s worth of ice to exploit.

The benefits of a terraformed summer home on the Moon are numerous. For example, if the Moon had an atmosphere as thick as the Earth’s, you could strap on a pair of wings and fly around in the 1/6th gravity.

The enormous gravity of the Earth would pull the Moon’s oceans around the planet with 20 meter tides. You could surf the tide for kilometers as it washes across the surface in a miniature version of the shallow water scene in Interstellar.

This might be the greatest sponsorship opportunity for GoPro of all time. Look out Kiteboarding, you’re about to get more extreme.

Everyone always wants to talk about terraforming Venus or Mars. Let them be, that’s too much work. The next time someone brings it up at D&D night, you can blow their minds with your well crafted argument on why we want to start with the Moon.

I can remember David A. Hardy illustrating a few articles on future human habitats on the Moon, showing people enjoying themselves flying around and swimming at just such a lunar resort. One of these was for an article in the sadly short-lived space and astronomy magazine, New Voyager. The resort was in an enclosed dome, rather than on the terraformed surface. The Scots space scientist, Duncan Lunan, in his book, Man and the Planets, also suggested that to prevent the Moon’s atmosphere from being lost to space, the whole planet should be contained with a kind of giant inflatable bubble. This is waaaay beyond modern technological capability, but not, perhaps, that of the future. So perhaps at some point in the far future, the Moon may also join Earth as a living, habitable world.
