How many other animals have been put into space and why? Looking into the subject, it’s quite entertaining. so here’s my top ten list of animals sent into space:

10. Flies

In 1942 the first animals were put into space. they were ironically flies. Fruit flies and corn seeds took a one way trip on a US V2 rocket, (you know the ones they built using Nazi technology and slaves).

9. Dogs

On November 3rd, 1957 the first animal in orbit was Laika, the Russian space dog. She flew aboard Sputnik 2 and died during the flight. The Soviets flew 10 more dogs on that programme until April 12, 1961 when Yuri Gagarin became the first man in orbit.

Belka and Strelka (seriously, who named these dogs?) were the first mammals to be successfully returned to the Earth after orbital flight in 1960. you can them in the picture. The other canine record holders are Veterok and Ugolyok, two dogs that spent 22 days in space before returning unharmed in 1966.

Strelka’s puppy, Pushinka was given as a present to the Kennedys and many of her descendants are known still today.

8. Fish

Several fish have visited space. specifically the species Mummichog, Japanese Killfish and Zebra Danio. The Killfish were in fact the only survivors of the Columbia distaster.

More than anything I was simply pleased to find out there is an animal called a Mummichog.

7. Spiders

Experimenting with low gravity environments is obviously a big reason behind putting animals in space. So can a spider build a web in orbit? The answer is yes. Anita and Arabella were two garden spiders that flew on SkyLab in 1973.

The webs were seen to be finer that on Earth and to have variations in thickness throughout each web, unlike the highly uniform webs spun on Earth. Anit’s remains are still kept in a jar at the Smithsonian for all to see. You can see her web above.

6. Cats

Two cats have graced the skies, both put there by the French. The first was Felix in 1963, who survived his trip despite having electrodes implanted into his brain. The second cat’s name does not seem to be obvious, but he did not survive. I can has spacesuit?

5. Newts

In 1985, the Russians sent 10 newts into space after amputating their forearms. They were trying to study the regeneration of cells in low-gravity.

4. Mice and Rats

Many mice have been into space. The US reportedly put loads of them up there in the 1950s, but only the first one survived. In the 1960s, China, the USA and Russia all put many mice into space and into orbit. Nothing much seems to have come of this so far as popular culture is concerned. Douglas Adams, may have had other things to say about that though.

Russia flew rats and mice, as well as hordes of other animals, during its Bion programs in the 60s and 70s. Bion spacecraft (shown above) were designed to test organisms in space. As you can see they look very comfortable. If only NASA had made them, they would have at least had cupholders.

3. Frogs

My favourite space dwellers are the Orbiting Frogs that were sent up in 1970. Why? Well of course it was to sudy motion sickness in space. Don’t you know that frogs get carsick?

The Orbiting Frog Otolith housed the bullfrogs for a week as they circled the Earth. Scientists measured their vital signs and once the experiment was over the simply left the frogs to work it out for themselves. Needless to say it pleases and disturbs me greatly that there are possibly still two frogs up there somewhere.

Also, Toyohiro Akiyama, a Japanese journalist, carried a tree frog with him on a visit to Mir in 1990.

2. Tortoises

The tortoise is held in my esteem on this blog entry because it is the unlikely holder of not one, but two space records! In 1968 a Russian Tortoise became the first animal to go into deep space when it orbited the Moon and returned safely to the Earth.

There must be something about Tortoises that Russian space scientists like (or dislike) because a Tortoise also hold the record for longest flight time in orbit. In 1976 two tortoise and a fish spent 90.5 days in orbit on Salyut 5. They were never recovered and the craft burned up during re-entry in 1977.

1. Monkeys

Of course I had to end with monkeys. On June 11th, 1948 a monkey named Albert was the first to be put into space by NASA. He was under anesthetic during the launch and never returned. Many other monkeys have famously been put into space.

In 1959, Able and Baker, a rhesus and squirrel monkey respectively, were the first to survive spaceflight. It sounds like the premise of a Warner Brothers’ cartoon. They were placed in the nosecone of a missile and shot nearly 400 hundred miles above the surface of the Earth and over a distance of 1,700 miles. They travelled at 100,000 mph for 16 minutes. Needless to say they experience G-forces above and beyond anything normal (Wikipedia says 16g).

Able died a few days later from complications related to one of his implanted electrodes, but Baker lived until 1984 in the NASA Spaceflight centre in Huntsville, Alabama, possibly running the place.

In 1961, Ham the Chimp was launched into orbit. He was been trained to operate his craft (seriously, Warner Bros again?). He survived and lived a life of luxury afterwards. He appeared many times on television and even starred in a film with Evel Knievel!

17 more monkeys and chimps were flown in the years that followed, by the US, Russia and France, including two that went up on one of the first space shuttle missions.

I would like to end on the tragic is the story of Gordo. A young squirrel monkey from South America, Gordo also flew in the nosecone of a missile. In fact he paved the way for Able and Baker to do so more successfully a year later. He rocketed upward and survived the 10g launch, to the delight of NASA supervisors. However, during the 100,000 mph re-entry, whilst experiencing a whopping 40g, Gordo’s parachute failed to deploy. The squirrel monkey, sealed in the nosecone, sonicly-boomed into the ocean, more than a 1000 miles from Florida. He has never been recovered.

10: Mars Then and Now

Two images of Mars taken over 100 years apart. The first was drawn by Eugene Antoniadi in 1894, the second is from Hubble during the close approach of Mars in 2003. Its interesting to see what they got right and what they got wrong. Notably the extensive system of Martian Canals, which Percival Lowell was so adamant existed and proved the presence of Martians.

9: The Surface of Europa

Back in January 1998, when this image appeared on APOD, the Galileo Mission was still sending back amazing new pictures from Jupiter and it’s Moons. This was around the time I first discovered APOD and have been checking it ever since.

8: Bubble vs Cloud

This 2005 APOD captured my imagination for some reason. You can really see a three-dimensional effect in this beautiful picture. The actual title of the image is ‘ NGC 7635: The Bubble Nebula’ but the phrase ‘Bubble vs Cloud’ stuck with me somehow. It just got me thinking about how dynamic all of these giant objects are, even if we will never see it for ourselves.

7: Close Up of the Face on Mars

After years of being told by people that there was a giant human face on Mars that an ancient civilisation had once created it was satisfying to see it for real and notice that ‘hey, there is no face’.

6: Binary Black Hole

This composite image shows the x-ray in blue and the radio in pink. You can see two black holes in the middle, which are each streaming out relativistic particles. These two objects are 300 million light years away! This APOD from April 2006 was the first time I had ’seen’ a black hole in any convincing sense.

5: A Sun Pillar

One of the things APOD does best is show not only planets, nebulae and other distant objects, but also some cool, Earth-bound astronomical tit-bits. This Sun Pillar is created by ice crystals in the atmosphere. They are best seen during the colder months.

4: Earthrise

This is a Christmas Eve APOD from 2004. The site has never been afraid to put up historical pictures or to be a little poetic when it feels like it. This image was taken around ChristmasEve when the three Apollo 8 astronauts were orbiting the Moon. They returned safely on December 27th, in time to see the 1967 Sunrise back on the Earth.

3: Hyperion

Like a 250km sponge, Saturn’s Moon Hyperion is covered in odd craters and has a density so low that it has led researchers to assume it made up of vast deep caverns. This image shows the moon in excellent detail. The images on APOD have steadily improved with improving technology over the years and this amazing Hyperion picture is a great example.

2: Blue Lagoon

Sometimes you see a picture that just takes your breath away. This APOD was just such a picture. This wonderful Lagoon Nebula picture, which to me, looks like a painting, was not taken by Hubble as many might think but by a 20″ telescope on Earth.

1: Venus Near the Moon

Not a grand finale in one sense, but a stunning picture never-the-less. What APOD has always done best are images like these, taken not by massive telescopes but by normal observers with affordable equipment. The stuff you can see with your eyes and appreciate instantly without explanation. This crisp, detailed image of Venus near the Moon sums up what so many of us like about astronomy, and why the subject remains accessible to just about anyone.

So thank you to Astronomy Picture of the Day for many years of service to the internet. May you long continue to wow us on a daily basis.

APOD is also available as a Google Homepage Gadget, a Netvibes Module, an Apple Dashboard Widget, a Wordpress Widget, a Yahoo Widget, a Windows Vista Gadget , as a Twitter Feed and probably loads more.

If you have other APODs you think deserve attention, leave a link in the comments thread so we can all see.

V838 Monoceroti Expansion (Hubble)

It wasn’t anything interesting until it happened but the star V838 Monoceroti, which had simply sat in obscurity, flared up in 2002 to become 600,000 more luminous than our own Sun. It didn’t take long for the star to fade back into the darkness but the Hubble Space Telescope managed to get quite a few pictures of it during its active phase. (Click for animated version)

In this series of images you can see how the star’s outer layers were first expelled and then cut away by the powerful radiation from the star. The event was made even more interesting by the fact that a ‘light echo‘ was seen. During the expansion the object appeared to expand faster than the speed of light - the effect was however merely an astronomical optical illusion.

The Egg Nebula (Hubble)

Also known as CRL2688, the Egg Nebula shows a pair of mysterious ’searchlights’ bursting out from a dense cocoon of dust surrounding a hidden, Sun-like star. We see the light escaping in the directions where the cocoon is thinner. Objects like CRL2688 are rare because they are in a phase of their evolution that is short-lived. Images like this one are very important to understanding how stars like our Sun will ultimately die.

The Sun in UV (SOHO)

The surface of the Sun is far more active than most people would think. This ultraviolet video taken by NASA’s SOHO spacecraft gives brilliant detail. It allows us to see one full revolution of the Sun on its axis, which normally takes about 25 days. In this video you can make out large flares erupting from the surface and the striking magnetic loops that seem to whirl about them as they go. (Full 512×512 MPEG Here)
Red Square Nebula Nebula (Hale/Keck)

Discovered in 2007, this ruby-like nebula may be the result of two interacting stars. If one star is dying then the material from it may be dragged into a disc around the orbits of both objects. Material can then only escape from the system along the poles of the disc, resulting in two cones leading out of the stars. When viewed from the edge these cones seem like two triangles. Here the system is seen in the infrared. Structures like this are rarely seen in nebula but there is in fact a Red Rectangle Nebula which is less symmetric but still quite interesting to look at.

Abell 39 (NOAO)

Here we see an almost perfect planetary nebula that sits about 7,000 light years away in the constellation Hercules. The dot at the centre is the original star, which - as it died - released the expanding gas shell also seen clearly here. The ghostly appearance of the shell is due to the blue-green filter used to take the image, which picks out the oxygen emitted light at 500.7nm.

Saturn’s Rings (Cassini)

This marvelous panoramic view was created by combining a total of 165 images taken by the Cassini wide-angle camera over nearly three hours on Sept. 15, 2006. Cassini was sheltered from the Sun’s glare by positioning itself behind Saturn. Ring structures are revealed here in detail as they brighten substantially at viewing angles where the Sun is almost directly behind the objects. These observations allowed Cassini to detected two new faint rings.

The Horsehead Nebula Swallowed Something (SCUBA)

Observers used the JCMT submillimetre telescope on Mauna Kea in Hawaii to take this image of the familiar Horsehead Nebula, who’s outline can be seen here. When observed at 850 microns, we are seeing the cold dust at temperatures close to absolute zero. This dust is deep inside the optical nebula normally seen, which is transparent at this wavelength. It seems from the image that the Horse has swallowed a ‘lozenge’ which is in fact a region of dense dust that may be collapsing under gravity. In fact this could be a star system in the making.

Gomez’s Hamburger (Hubble)

Arturo Gomez found this odd object in 1985 and it became known as Gomez’s Hamburger for obvious reasons. It is actually a proto-planetary nebula, an earlier version of Abell 39 perhaps. The curves of light (the bun) are reflecting light from the star which is being obscured by a thick band of dust (the burger). The whole thing is only only a fraction of a light year across and located 10,000 light years away in Sagittarius.

The Solar Spectrum (NOAO)

If you could catch a rainbow and put it under a microscope you would see that it was not a continuous blend of colours. Along the width of it would be seen, scattered irregularly, dark patches. Atoms and molecules in the Sun’s atmosphere pick out specific frequencies of light and absorb them, diminishing their intensity by comparison. This images shows the spectrum of light from the Sun stretched out to make these absorption lines visible. We use the reverse of the idea (emission lines) when we make coloured lights. For instance, we excite sodium atoms to emit a signature orange light in street lamps. In this image you can see two prominent dark bands in the yellow-orange section which are the absorption due to sodium.

Update to This Entry

The Sombrero Galaxy in Infrared (Spitzer)

By looking at things in different wavelengths we can see much more than meets the eye. This image is a perfect example. Just as with the Horsehead image above we are seeing cooler material. This time it is dust in the Sombrero galaxy. The red ring is a thick band of dust encircling the whole galaxy. In the optical, this dust ring is what gives the Sombrero its distinctive black, obscuring line.

Oddities in the Orion Nebula (Hubble)

Deep within high resolution images of the Orion Nebula taken by Hubble we can see dark blobs. When you take a closer look you can see that these are like little flattened blobs. Some show a dim, red glow at their centres, others are just dark. These are proto solar-systems.

The red glowing is a protostars attempting to burst through and the dark disks are thick dust regions where one day planets may form. 6 billion years ago, this is what our Solar System may have looked from very far away.
