European Space Agency Launches New Orbital Supply Ship

erik.martino brings us a story about the European Space Agency's successful launch of a new type of cargo ship to resupply the ISS. The first Automated Transport Vehicle (ATV), named after Jules Verne, is the "very first spacecraft in the world designed to conduct automated docking in full compliance with the very tight safety constraints imposed by human spaceflight operations." Among other things, it carries water, oxygen, and propellant to help boost the ISS to a higher orbit. We recently discussed NASA's need for a new cargo transport system. Quoting: "Beyond Jules Verne, ESA has already contracted industry to produce four more ATVs to be flown through to 2015. With both ESA's ATV and Russia's Progress, the ISS will be able to rely on two independent servicing systems to ensure its operations after the retirement of the US space shuttle in 2010. It incorporates a 45-m3 pressurised module, derived from the Columbus pressure shell, and a Russian-built docking system, similar to those used on Soyuz manned ferries and on the Progress re-supply ship. About three times larger than its Russian counterpart, it can also deliver about three times more cargo."

Why do you think that?

The automated docking is Russian. They have been using it since the 60's. I wish America had elected to do this, but we did not. Our approach will be to bring crafts up close, then allow an arm to hook up and pull the craft in.

There is a significant difference between the respective docking systems of the Progress docks and the ATV.
The Progress uses a multi-antenna radar system named KURS.
The ATV uses a specifically made video meter (PDF).

Nah, the docking computer is for girls. It takes up a ton of space that is essential for loading up with consumer goods for the Sol to Barnard's Star cargo run. Definitely not worth it until you get a much bigger ship...

You do realize that crash happened during manual docking trial ? i.e. that Progress dockings were always automatic, but they wanted to train emergency manual docking procedure and failure was indeed human factor ? (Murphy's laws in action i'd say).

Foale's Increment proceeded fairly normally until June 25, when during the second test of the Progress manual docking system, TORU, the resupply ship collided with solar arrays on the Spektr module and crashed into the module's outer shell, holing the module and causing a depressurisation of the station, the first ever on-orbit depressurisation in the history of spaceflight. Only quick actions on the part of the crew, cutting cables leading to the module and closing Spektr's hatch, prevented the crew abandoning the station in their Soyuz lifeboat.

You can't just "park" a ship a few miles from the ISS. The ISS orbit is constantly decaying and being boosted. You would have to exactly match its orbit to the ISS to keep anything "parked" anywhere near it. If its not doing anything useful there is no point burning the propellant.

You could maybe make a case for attaching all these ships to the ISS and growing its storage, lab or habitation space, but there are no docking ports designed for this, they would grow the mass of the ISS requiring more propellant to maintain orbit. They would also just complicate power, pressurization, etc so if they aren't doing anything useful they probably aren't really worth it. To make them useful on orbit would substantially increase the expense to build them and reduce their cargo capacity.

Otherwise this is awesome news and cheers for ESA. It is about time the NASA/Russia stanglehold on the ISS was broken. NASA and the U.S. in particular just haven't been sane managers of the ISS or just about anything else about the manned space program since Apollo ended. Its especially sad all the money that is being poured in to the cosmic ray detector that would actually do valuable research on ISS for a change, but NASA probably wont launch it.

It remains to be seen if ESA and Japan can make the ISS useful and worth the expense but they sure can't do any worse than NASA in this regard.

Yes, it's tragicomically wasteful. I don't understand why they can't design a cargo/supply ship that STAYS IN ORBIT. I mean, sure, let's go ahead and de-orbit the ISS trash in some kind of disposable carrying module They could, but in doing so they'd have to redesign it from its current philosophy of disposable carrying module to that of reusable spacecraft. Then they'd have to design a new disposable carrying module to hold all the garbage, which people like you would again decry as "wasteful" and demand it be refueled and parked up on blocks in the ISS front yard "jest in case we needs a 'nuther pickup truck someday".

The whole concept of multi-million-dollar disposable rockets is just ludicrous! The rockets are all disposable. The spacecraft you want to "save for later" is just the small bit at the end of the rocket.

Look, this is stupid. Space travel is inherently costly in terms of resources. You just can't look at it the same as (say) driving a semi from Los Angeles to Phoenix. So much has been expended in getting that tiny cargo there that arguing over throwing out the box it came in is just ridiculous.
