Tracking ESA's ATV-4 "Albert Einstein" the coming nights

If all goes well, ESA's cargoship ATV-4 "Albert Einstein" will be launched from Kourou on top of an Ariane rocket tonight at 23:52 CEST (21:52 UTC). It will dock to the International Space Station ISS on 15 June. A live webcast of the launch will be featured here.

During the 10 days it takes to get to the ISS, it will make several visible passes over Europe, starting the coming night (June 5/6). On the night of June 14/15, it will be possible to see ATV-4 and the ISS pass around the same time, closing in on each other just hours before docking.

For those of you who want to try to photograph an ATV pass themselves, I have written a tutorial, that is featured on ESA's ATV weblog.

Visible passes for NW Europe the coming night (June 5/6) occur at approximately:

* 01:47 CEST (23:47 UTC)
This is a pass that is very favourable for the UK, Netherlands and mid-Germany. In the Netherlands we will see the ATV pass right through the zenit! Here is a trajectory card (valid for Leiden, the Netherlands: elsewhere in Europe the trajectory will be different! For elsewhere in the Netherlands, the trajectory might slightly shift) and a map of the relevant groundtrack:





* 03:20 CEST (01:20 UTC)
A pass in twilight over a.o. the southern UK and France (but also visible from the Netherlands and Germany):



Please note that the spacecraft is actively manoeuvering, and this means that the listed pass times are approximate: there might be differences up to a few minutes with the real pass times.

If you want to get an accurate sky trajectory map for your own location, then Heavens-Above should have predictions available from the moment of launch. A live ground tracking application is available here (it will tell you over which part of the globe the ATV is, but not where in your sky however).

If your are able to run your own predictions (e.g. with Heavensat), then ESA has kindly made TLE's available here.

The relevant TLE for tonight (5/6 June) is:

ATV-4
1 00000U 13156A   13156.95908050  .00000000  00000-0  11891-3 0  0008
2 00000 051.6512 167.2588 0016658 269.7524 354.7951 16.02929810 00002

Depending on the illumination conditions, the ATV can reach mag. +1 and hence be easily visible by the naked eye during a favourable pass.

Visiting ESTEC for the #AndreTweetUp, an in-flight call with astronaut André Kuipers

On 29 May 2012, some 80 space and twitter enthusiasts gathered at the European Space Agency's (ESA) ESTEC center in Noordwijk, the Netherlands, for a "tweetup" called the #AndreTweetUp. This author was among them.

A "tweetup" is a gathering of twitter users. ESA organised the event around a live in-flight call with Dutch astronaut André Kuipers who is onboard the ISS. Eighty followers of the twitter acount of  André Kuipers were invited to attend, after a selection procedure that included the formulation of a question to Kuipers.

Ten of the 80 people present, actually got to ask that question during the live in-flight call . The event  included two lectures, a guided tour through the ESTEC facilities, and ended with the live video in-flight contact.

For this author, who was among the lucky 80 to be invited (but alas not among the even more lucky 10 who got to ask their question to Kuipers), this kind of event was new. I jumped the twitter bandwagon late, a few months ago, and untill this #AndreTweetUp occasion, I had never heard of "tweetups".

So I had no idea what to expect. I half expected a hall full of Sheldon Coopers, dressed in Star-Trek costume, mumbling "fascinating!". Or 80 Wolowitzes, trying to hit on the ESA hostesses and talking about the space toilet they designed.

The reality was more benign. Indeed, there were a few people walking around wearing an astronaut's flight jacket covered in space-related patches (mind you: one of those actually was a genuine astronaut: ESA's Christer Fuglesang). And there were a couple of tweeps that seemed to build a life around this kind of events, recognizable by their paraphernalia that included custom t-shirts  and keychains with the words "tweetup" and "space" prominent and a mascotte in the form of a space-suit clad bear called Hughie:

But all of these people turned out to be quite nice and normal! The evening before the event, I had a great time as part of an informal evening drink with a few of them (including but not limited to  @travelholic, @4tuneQkie, @DanielScuka and @rtimmermans) in "Einstein" in Leiden:

You see: this almost looks like normal people! ;-)

Of course, this wouldn't do, so during the tweetup ESA had us all dressed in nerdy t-shirts with the ESA logo and "#AndreTweetUp" on it  ;-)


To bring in the Wolowitz factor, one of the things they let some of us do, was remotely move a robot arm on a future moon-rover located in a lab in Italy. Below is me, giving the command "move arm to left" (no word yet whether they got the rover out of the ditch again).

The program was varied and started with a presentation by ESA's Walker including music videos that amongst others Elton John had made especially for this ISS mission. Walker told that by teaming up with Elton John, the amount of website hits on the ESA mission page increased a factor 2000!

Next we had a very fine video presentation by one of the attendants, Remco Timmermans (@rtimmermans on Twitter), who had travelled to Baikonur to see the launch Soyuz TMA-03M blasting off Kuipers to the ISS.

We were then split-up for a guided tour through the ESTEC facilities, including a peek in the clean-labs (where alas photography was not allowed) and a 3D presentation where we got a virtual tour "trough" the ISS.

And of course, a notable number of the attendants duly tweeted all their experiences as the day progressed (photo shows a few of them listening to an explanation at the Russian Foton capsule, and tweeting about it):



The hall where we tweeps were settled, had enough to see too, as it included amongst others a life-size mockup of the European ISS module Columbus, a genuine Foton capsule and  the genuine Atmospheric Reentry Demonstrator (ARD) capsule, the only European capsule having been to space and then re-enter and land safely:

Next Swedish astronaut Christer Fuglesang lectured us on his experiences with travelling to the ISS onboard a Space Shuttle, and introduced the very varied research done onboard the ISS:

And then it was time for the big moment: the live in-flight video call with Dutch astronaut André Kuipers who is flying onboard the ISS as part of the PromISSe mission. The contact happened at 15:55 UTC (17:55 CEST) while the ISS was over the Galapagos and S-America, by means of a TDRS relay.



Here are some of the lucky 10 that got to ask their question lining up:


Even a "celebrity", soap-actress Babette van Veen (worldfamous in the whole of the Netherlands), got to ask a question (at ~6:15 in the video at the bottom of this post):



Below is a video showing parts of the in-flight call (as the memory card in my camera had filled up, I had no space left to film the complete in-flight call. I thought 8 Gb was enough, but no...).


It was fun and interesting to be present at this happening, and I wish to express a sincere "Thank you!" to the people of ESA and ESTEC for organizing this day!
