A historic day…

Wow… I don’t know how I’m going to write up what happened today, I really don’t. It was just… incredible, really, a day of highs and lows, soaring joy and fleeting despair, celebration and pessimism… Ok, let’s give it a go…

It’s now 8pm here in the UK, and I’ve been on this laptop since 6am this morning with only a couple of brief pauses for food, water (well, tea, Brit, you know…) and air. I’ve been flipping between Twitter and Facebook so many times through the day I’ll probably develop RSI in my typing fingers, and my keyboard is screaming at me “Enough! Leave me in peace!!!” But not yet, not yet…

In the last post on this blog I wrote about today’s events leading up to the deployment of Philae, all shown live on a fantastic ESA webcast. What happened next? Well, there was then a two hour gap, filled with interviews with talking heads and re-runs of videos and clips. I decided it was time to open and eat a handful of my “Good luck” peanuts – it’s a tradition now for us spacey types to eat peanuts on a landing day…


…but then suddenly people started Tweeting and FB posting about blurred images glimpsed on screens over the webcast – could these be the much-anticipated “farewell” shots taken of ROSETTA by little Philae after it had started to drop away? Maybe… but they were very blurry, out of focus, smeared…

What the..?? Did that mean the camera wasn’t working? Was something wrong??

No, neither of those… the pictures “doing the rounds” were just poor quality screen grabs of poor quality images, and when the real image was released, well, the place erupted and the internet threatened to melt. This is what we saw…

farewell 1b

WOW!!! LOOK AT THAT!!! That’s the ROSETTA orbiter, top right, one of its huge solar array wings being lit by a burst of sunlight… That picture was taken by little Philae as it fell away, plunging down towards 67P, and it’s been hailed as an “iconic” image already.

But that was just the warm-up act. Soon after that Farewell image was shown, to everyone’s utter amazement it was announced that the OSIRIS cameras had managed to image Philae as it fell away – and the pictures were ready to be shown by OSIRIS PI Holger Sierks!! WHAT?? REALLY??? Were we dreaming??? Did we just imagine that??? OSIRIS images, barely a couple of hours old, being released into the wild???? Could it be true???? What was the catch?

It was true, and there was no catch. A delighted Holger Sierks beamed from ear to ear as he shared his team’s images with the watching world. The first was a wide angle view, showing Philae as really just a bright “star” near the middle…

But the second one was much more promising… little Philae looked bigger, over on the left hand side of the image…


Oh the cheers and applause at ESOC when that one was shown! But then Holger showed a zoomed in view of that second image and the place just went nuts…

farewell 1

Look… a spaceship… dropping towards a comet… its legs outstretched…

A fantastic image, another icon right there… but I thought it could be tidied up a little, and after a little work this is what I pulled out of that, re-orienting it to make it look like it was actually going in for landing, too…

farewell 4b

Un-be-LEE-vable!! And a good sign, surely, for the rest of the day…?

I have been extremely critical of the OSIRIS team on this blog, with, I feel, very good reason. Their image hording in the run-up to today has been shameful. But today, credit where credit is due, they did a fantastic job taking and then releasing their images so quickly. Well done to them.

Another pause in proceedings then, and the ESA webcast slipped back into “lurk” mode, showing live shots of the ESOC control room without commentary, but accompanied by a bizarre and migraine-inducing jazz soundtrack. I know jazz has its fans, but I’m not one of them. It’s just not music to me. So this interlude was torture for me, and on Twitter and Facebook I *pleaded* with the ESA team to find another CD in someone’s car, but to no avail. So I made this image, which many Brits “got” but left others baffled… Which camp do you fall into, I wonder? ;-


With an hour or so left to go until the receipt of signals from Philae confirming she had touched down safely, suddenly things started moving quickly, and the live broadcast resumed. But, as is often the case now, it was Twitter which provided the next image – an image taken by Philae, looking down at the comet as it dropped towards it!


Some very familiar features on that, but that wasn’t the point, the point was that the lander was working – and was aimed – perfectly at that point, which was a huge confidence boost!

And then all we could do was sit back and wait… as the predicted/time delayed time of Philae’s “I’ve landed!” communications window opened, everyone held their breath, and waited. And waited. We watched the live feed from mission control, and as the minutes ticked by without any signal coming in we noticed, with alarm, how worried and tense they all looked in there…


… and when we saw them reaching for their mobiles we did wonder if the ROSETTA team was going on Twitter themselves in an attempt to find out what was going on…


And still the minutes ticked by. I sat here, laptop on my knee, Peggy jumping on and off me, bored and feeling ignored, oblivious to the way my insides were absolutely tying themeselves up in knots –

Then, a cheer, and another, and applause, and suddenly people in mission control were hugging and cheering and slapping each other on the back…




Success? It looked like it! Why else would they be cheering like that? Then a Tweet came in, and was retweeted again and again and again…


Philae had phoned home! The lander was down! It had done it!! So the question now was: when would we see the images of the surface?

Because of the time delay it was always going to be another half hour before we saw anything from the lander after that first confirmation signal came in, so all we could do was wait… again

Eventually images started to trickle out – not because they were released, but because they were glimpsed on screens being shown on various live feeds and then grabbed and shared by space enthusiasts watching. So, not long after landing, we were seeing views like these…




For a while there was HUGE excitement online when an image began circulating which looked very much like it was actually a “selfie” taken by Philae on the surface of the comet!!


…but at the time of writing (almost half nine, good god!!!) the consensus seems to be that that is NOT a surface image, but an image taken on Earth when the lander was being tested. Shame…

And then, out of nowhere, rumours began to circulate that all was not well with Philae. People were saying that something had gone wrong with the landing gear, namely the harpoons hadn’t fired to secure Philae to the surface. In good news, the “ice screws” were apparently turning, hslping to hold Philae down, but the loss of the harpoons was potentially a big blow… which led me to create and post this…


Sorry, I just couldn’t resist it…!

Time passed, rumours blossomed then died down again, until eventually ESA announced that they would be holding a media briefing, with the latest news about the mission. The time scheduled for the conference to begin came, and went… nothing… It was rescheduled, and that time came and went too. I know I started to feel all kinds of bad feelings about the mission, and wondered of they were preparing to break Bad News to us. When the media briefing began, it was clear pretty soon that that wasn’t going to happen. But the situation with Philae was… well… complicated…

It turns out that Philae landed pretty much smack bang in the middle of her planned landing zone, but then instead of her leg harpoons firing and securing her to the surface something went wrong… and she went back up again, bouncing gently off the comet back up into the air, where she turned around. At this point her comms link with Rosetta fluctuated, coming and going, which had turned the team quite pale, but then Philae had come back down again, and this time had stayed down. So she had, effectively, landed TWICE on 67P. How incredible is that? Mankind’s first landing on a comet was actually a double landing!

And the situation after that? Well, Philae had taken images, as planned, and gathered a lot of data very quickly, but the comms window with Rosetta had shut before Philae had had a chance to send everything back, so we weren’t going to see the pictures of the surface tonight, which was a huge shame, obviously, but that’s just the way it is, and after all the wonderful events of the day it would be a shame to dwell on that so we’ll just have to be patient and wait until tomorrow for those. And there’s going to be a media briefing at 1pm GMT tomorrow, when everything will become a lot clearer. (Typical… I’ll still be at work… I’ll have to catch up when I get back…)

One thing they will want to do is *find* Philae. It seems that when it made its first landing it was right on course, and came down exactly where planned, i.e. around here (circled in red)…


…but when it bounced where did it end up? How far away did it travel? Some commentators suggest it came back down as far as 500m away from its original landing site, but in which direction? The lander could be anywhere. No doubt the OSIRIS team will be carrying out blanket imaging of the comet and scouring their images for any sign of the lander. They’re probably taking those pictures already.

…and that was the big day.

It’s now almost 11.30pm, and I’ve been up since 6am, and that was after just 3 hours sleep. I feel so tired I could lie down on that floor over there and sleep for a week, I swear, but I wouldn’t have missed any of it for the world. It has been an absolute privilege to follow history being made from my own home – from my own sofa in my own home, at that – and to share the events of the day with friends and strangers from around the globe. Today we were witnesses to history. Today was mankind’s first ever landing on a comet, and that will never happen again. There are so few firsts left in space exploration. We have already had the first man in space, the first man on the Moon, the first landings on Mars, Venus and Titan, and asteroids. The first landing on a comet was one of the few firsts left – along with first manned landing on Mars, the first landing on Europa and the first fly-by of Pluto – and today we watched that happen almost in real-time.

For countless centuries we viewed comets with fear, dreading their appearance in our skies. Eventually our dread turned to fascination, and we eagerly trained our telescopes on them to learn all we could about them. Eventually we spied on them with spacecraft, taking the first close-up images of their strange, irregular shapes and surface features, but still craved to know more, so we designed and built a spacecraft which would land on one and let us stare straight into its eyes and heart, and see its icy soul. That’s why, tonight, after a journey of ten years and billions of miles, and a tour of the inner solar system, a plucky little spacecraft is sitting on the surface of Comet 67P, and why we are, in between yawns, rejoicing.


And with that it’s time for me to call it a day. I hope some of you have enjoyed reading about how one space enthusiast watched history being made today, and I hope that you were able to follow today’s events from wherever you were, too.

More tomorrow. Bed beckons. Goodnight.

And goodnight, little Philae, wherever you are.

  2. Very impressive Stuart. Like the Jazz photo!

  3. Stu, above you wrote:

    When you look at DLR‘s Page

    you will find a line that reads:
    „ DLR Mitarbeiter können den (internen) Live-Stream hier verfolgen“
    „DLR employees port to internal / protected live stream“


    Boasting „live TV-coverage“ DLR is definately UNWILLING to share information they have with the public.

    Those DLR‘s you see, take their smart phones and dial into the ‚protected info channel‘ DLR doesn‘t want you to see.

    Stu, lets make a valid test. Above I see the TV-cast image looking over a controllers shoulder seeing a Philae close-up image of 67P‘s surface on his screen.

    Since you are impressingly experienced, could you find out by when DLR releases this image officially and then publicize the time in between.
    Would be great!

    Sorry for my poor English (not my mother tongue)
