ATV-CC decommissioning: Going, going…

Formatting, disconnecting and – Hop! – dismantled! Decommissioning the ATV Control Centre, especially the Main Control Room, is a long task, with a bit of nostalgia. The operation will last two to three months. A team of...

Next up… Orion!

Louis, I think this is the beginning of a beautiful friendship…. Post by NASA’s Orion Spacecraft.

Great view of ATV-5 smoke trail

And on board the ISS, astro Terry also grabbed an amazing photo of ATV-5 reentry! Final view #ATV5 Georges Lemaître entering Earth’s atmosphere. It was surprising to see how high the smoke trail was. pic.twitter.com/gt6kiBqJSq — Terry...

Update 14:51CET

ESA’s Charlotte Beskow is working on console with the ATV-5 Engineering Support Team, and just sent this in. Half the team have dreadful colds (probably as a consequence of the cold weather last week plus the rather long working hours of the last few days). It is wonderful what aspirins, vitamin C and motivation can do… In fact, the only thing that would keep us at home right now would be a major calamity. ATV5 is quiet. Following yesterday’s exertions, George is remarkably well behaved. Perhaps he is a bit tired and resigned to his fate. If yesterday was a bit like Monty Python (think of the scene with the gallant knight...

Update 14:41 CET

ESA’s Charlotte Beskow, working on console with the ATV-5 Engineering Support Team, just sent this in. The final hours… What can be done, has been done. The day shift has been on console since this morning, and the night shift has reappeared in the control room to follow the final hours. Most people are carrying cameras, 100% conscious of the fact that today will never be repeated. Right now the word ‘never’ has a special ring to it. – CB

Spotting ATV-5 Sunday evening

First: A sincere thank you to everyone who spotted ATV-5 last night, Saturday, 14 Feb, and shared their pictures during the last, best, overflight above Western Europe, between about 18:10-18:16 GMT. We saw some wonderful photos via...

What happens on Earth when ATV reenters?

This is a repost of our 2013 interview with Holger Krag, head of ESA’s Space Debris Office, at ESOC,  ESA’s Space Operations Centre, Darmstadt, Germany, during the ATV-3 reentry. His description of the planning and precautions for...

Green to go: ATV-5 in nominal orbit

Quick update from the mission director here at ATV-CC: After today’s successful, if a little sad, undocking, ATV Georges Lemaître is in nominal status, in free-flight orbit beneath and ahead of the ISS. The vessel is functioning as expected, and the team here will maintain it more or less as is until tomorrow’s reentry manoeuvres (we’ll update the blog timeline a bit later with details). Ground controllers will conduct a few minor in-flight procedures, including one Solar Array Drive Mechanism (SADM – What’s a SADM?) cleaning. Tomorrow’s reentry activities for the operations teams start at 12:29 CET, with impact expected around 19:12 CET. More details to follow.

Got questions? We have answers

A repost of our update on 14 January: We saw a question yesterday in Twitter from someone, and now we can’t find the tweet. 🙁 But we did note down the query: .@esaoperations why won't there be more ATVs? What will replace their capabilities? Thanks. Regardless of their source, they’re good questions! ATV-5 Mission Manager Massimo Cislaghi replies to the second point: There no 1:1 replacement to the ATV, but rather there will be a redistribution of its capabilities among the rest of the ISS servicing fleet, i.e. Dragon, Cygnus (when back in operation), HTV and – of course – Progress, this last vehicle being to my knowledge the only one capable...
