Here’s another astounding image taken by Thierry Legualt, known for his ground-breaking astronomical photography. It shows space shuttle Endeavour docked with the International Space Station, on July 26th 2009.

One can’t just take a snapshot of the ISS – even with the most powerful and sophisticated equipment. It needs to be backlit, and the Sun is the most handy light to use. But consider this: the ISS was 500 km away, and moving at a speed of 7 km/sec (that’s 25,000 km/hr!) and the transit across the Sun took just 0.75 seconds. Now that’s planning.

Interestingly, when the Endeavour docked on July 15, a new record was set for space-vehicle occupancy – the 13 people  of the combined crews.

July 21, 1969: One small step .. Three smart cuts …

Neil Armstrong on the Lunar Surface, July 21st 1969

Granted, it was an American achievement. The Apollo mission was quintessentially American and set the iconography for the next generation. They paid for it. They did it. It was theirs to use as they pleased.

But dammit – the Moon is not the 51st State of the Union. And just because there are 5 US flags scattered on its surface (fluttering, the CTists would have us believe), does not mean the Moon resides within an American time zone. When events happen on the Moon (or anywhere else in the Universe except Earth), we conventionally mark the time in Coordinated Universal Time (UTC). Even NASA does this.

But ask anyone and they will tell you man first walked on the Moon on July 20th, 1969. You see it in books, on quiz shows. Yet NASA agrees with me that Neil Armstrong took his first lunar step on July 21st, 1969 at exactly 02:56:15 UTC. I know this because July 21 happens to be my birthday.

It had been a long night following the landing and I was dead tired when the wake-up bell rang and it was really frosty outside. The first thing I did was to listen to my radio and caught the news a replay of Armstrong’s, “One small step for [a] man, one giant leap for mankind.” I couldn’t believe my luck – the first moon walk on my birthday! And I was a teenager!

That luck didn’t last long. I was slow in getting up and was late for everything. I was so late that I was still showering when I was supposed to be at breakfast and I was summoned to a visit with the housemaster – the fearsome Rocco Erasmus, part-time radio DJ, part-time teacher and full-time sadist. He gave me three vicious cuts with his long cane, and sent me on my sorry way.

That evening after supper, my friends and I huddled together against the cold, looking at the moon. It was high in the Western sky – a half moon. One of the boys thought he could see the lunar module. We laughed. Then another wondered, “What if the rocket doesn’t fire?”, and we stopped laughing.

Before going to sleep on my first night as a teenager, I took one last look at the setting moon through the window, and sighed in relief that the rocket had fired and that the astronauts were safe. I felt my welts. All in all, it had been a good day.

Asleep on the Moon

The Apollo 11 lunar module (LM) Eagle touched down on the surface of the Moon at exactly 20:17:39, July 20th, 1969 UTC (previously known as GMT). That’s 40 years ago today. Neil Armstrong and Buzz Aldrin, huddled in the ungainly LM had left the command module (CM) Columbia almost three hours earlier. Alone in the CM sat Michael Collins, intensely following Eagle’s progress. After visually inspecting Eagle for damage he watched it slowly disappear from sight below him.

The ride down was not uneventful. A number of alarm signals distracted the astronauts but these were simply training errors, not faults. The tiny computer on board could not process all the tasks in real-time so had to postpone them, at which point an executive overflow alarm would sound. Their training had not catered for this.

Much more serious were the navigation problems. Armstrong had to take semi-manual control of the spacecraft when it appeared that it wasn’t going to land on the designated spot. When the rockets were turned off, they had only 25 seconds of fuel left.

It was a Sunday. The radio had been on all day. Lights-off for the juniors in the boarding house was 8:30. Not being in bed by this time or making any noise after it was an offence, punished by a caning. But this evening was different. The ever-vigilant prefects who usually made our lives a misery were away, listening to the radio. Our domitory was a cacophany of crackling radios. Sadly, it wasn’t long before an officious boy-Hitler put a stop to this. Then, like most of the other boys, I lay in bed in the darkness with a little earphone in my ear, literally glued to every sound popping out of my little radio.

Normally we would all be asleep by 9 PM. But I couldn’t have slept even with nothing to listen to. It was so exciting. That unexpectedly long descent made me start to fear the worst. But then at almost 10:20 (local time) a flurry of activity and Armstong’s, “Houston, Tranquility Base here. The Eagle has landed.” What relief!

Confident that they would immediately step onto the surface of the Moon, I woke up the boy in the bed next to mine. “Wake-up! They’ve landed! They’re going to walk now!“, I whispered. After a bit of swearing he plugged his earpiece in. And then we waited and waited. I drifted off for a while but woke up a little later only to hear that the astronauts were resting! Resting? How could they possibly be resting? I felt sorry for Michael Collins. What wouldn’t he have given to be on the Moon? And all his colleagues could do was rest!

By now it was past midnight and I happily gave up the fight. It was the next day – July 21 – and my heroes would take their first steps on the Moon on my birthday!

First Moon landing images released

Earlier than I had hoped, the first LROC images of the moon landing sites have been released by NASA. These images were captured before the LRO reached its final mapping orbit, and are at about of a third the resolution of future LROC images. Click on the image below to see the original uncropped image of Eagle sitting in its landing site.

This image of the Apollo 14 landing site is a lot more interesting showing the astronauts actual foot marks.

I think it was marvellous of NASA to release these images before the 40th anniversary of the first landing by Apollo 11.

However, even though these images were taken within the last week, I doubt that the conspiracy theorists will accept this evidence either.

The Moon Shot: like yesterday

The world is celebrating the 40th anniversary of the Apollo 11 mission to the Moon.  Today – July 16 – marks the day exactly 40 years ago when the massive Saturn V rocket lifted itself off the surface of the Earth and accelerated its payload of three brave astronauts towards the Moon.

Unlike millions of people around the world, I didn’t see the launch on TV. Not because I was too young – simply because in those days South Africa didn’t have a television service. (Interestingly, it was the outcry from not being able to see this event live that, more than anything else, eventually forced the rabidly autocratic and Calvanist apartheid government to allow a television service).

I remember the launch as if it had happened yesterday. I was a 12-year old boy at boarding school in Johannesburg. It was a cold Wednesday afternoon and we had just finished a shortened soccer practice. A bunch of about eight boys gathered around my small Panasonic transistor radio, huddled against the cold wind on a grassy embankment on the side of the field. The excitement had been building all day and now it was almost unbearable.

When, at around three-thirty in the afternoon, the countdown began, our silence was only broken by our soft mimicking of the commentator: “Thirty seconds and counting. Astronauts report it feels good. T-25 seconds. Twenty seconds and counting. T-15 seconds, guidance is internal. 12, 11, 10, 9 … ignition sequence start … 6, 5, 4, 3, 2, 1, 0 … All engines running. Liftoff! We have a liftoff … 32 minutes past the hour, liftoff on Apollo 11. Tower clear.” (Play audio)

We knew the sequence exactly. We had listened to many of the previous Apollo mission launches and even mimicked the commentator’s American accent. We’d heard it all before.

But this was different. This was the mission: to the Moon! My heart was racing faster than the soccer coach could drive it up. There was an audible sigh of relief when Armstrong crackled, “OK, we’ve got a roll program”. We all made the roll with our hands. It was a moment to hug each other. Of course, we didn’t.

Later, when the broadcast stopped, we walked back to our House as if floating on air. The biting wind went unnoticed. I think we intuitively understood then that we were citizens of the World and together with millions of our fellow World citizens, we were celebrating this fact, looking up to the sky. It was a very special moment, and I wonder if my son – the same age as I was then and at the same school playing on that same grassy bank – will ever experience a moment like it.

I will be reliving the entire mission – this time with the visuals I missed the first time round – on the site We Choose the Moon. And I hope that a bit of my excitement rubs off on my media-numbed kids.

Volcanic eruption filmed from space

More space-based stuff – this time an amazing video of Sarychev Volcano (Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009. It was filmed from the International Space Station.

It’s breathtaking. The speed of the Space Station gives it a full 3-D look. You can see the a pyroclastic flow descending and a vigorously rising eruption plume.

You can find high-resolution images of the same event at NASA’s Earth Observatory site.

First hi-res images of the moon

The first high-resolution images from NASA’s Lunar Reconnaissance Orbiter (LRO) have been have been released. The LRO reached the moon on June 23 and the two cameras on board, collectively known as LROC (Lunar Reconnaissance Orbiter Camera), were activated on June 30.

The images were taken over the region in the lunar highlands south of Mare Nubium (Sea of Clouds).

This image shows a region 1,400 metres wide and features as small as 3 metres wide are discernible. What makes this exciting to me is that this is a very human scale. You can actually imagine yourself walking the short distance, through a museum of craters. The smaller craters would be no bigger than a suburban swimming pool.

I also can’t wait for images from the original landing sites – presumably the tracks left in the sand by the lunar buggy would be visible.
