Bernd Berger's passing Blog The ATV
This morning it started according to plan, the first ATV, named Jules Verne. It was completed some time ago and originally he should already start last year. The shift is not due to the ESA but the slow expansion of the ISS: the main task of the ATV is to supply the ISS and because it is much more powerful than the previous Progress transporter need it only if the ISS is manned by more people than the current 2 -3 permanent crew. That might be the case now soon after first In October the European connection node (named by NASA Harmony) was started are now coupled to the gradually more labs. The start made Columbus, the next shuttle flight is the Japanese Kibo module to do so.
Why do you start the ATV? Contrary to what it thinks the first ATV is to replace any emergency solution to the failed shuttle flights, but a contractual power of the ESA. The ISS costs money both in construction as in maintenance. Unlike the Spacelab Europe does not want to pay for the NASA flights and so there is payment in kind. NASA got called for two modules Node 1 and Node 2 as payment for the launch of Columbus. Russia got hardware such as computer systems for the launch of astronauts in Soyuz capsules and the ongoing operating costs paid by Europe per year to start a ATV.
The ISS will be served by a total of three transport systems: Progress capsules: They are quite old and upgraded Soyuz capsules. Gutted, without life support system can typically get about 2,300 kg of cargo each capsule. Progress can be especially dry cargo, so food transports, to get fuel for the ISS drive system. You can transport liquids and air only to a small extent. warehousing The same applies to have the orbit of the ISS for the ability. About 3 Progress flights are taking place per year. The Japanese HTV: The HTV is a counterpart to the ATV. it is with a pivoting load version of the Japanese H-2A launch has yet to complete its maiden flight. the HTV will not link autonomously, but only approach the station and then detected by a robot arm on the Russian module and connect it. With a launch mass of 16500 kg 5500 kg freight it transports of any kind. As the only transport medium also complete racks. The European ATV is the most powerful of all three. In addition to 7667 kg cargo of any kind, it also carries 4700 kg of fuel to lift the space station itself. Without this fuel, the ISS would sink slowly and eventually burn up in the atmosphere. The take-off warehousing mass of an ATV is 20750 kg. Before the retirement of the space shuttle of course there are these. In the latter of Europe MPL containers can about 9..4 tonnes of freight are brought to IOSS and the drive of the space shuttle, the station is currently raised regularly.
It is clear that the ATV is extremely important for the ISS. Firstly, an ATV has the capacity of 5 Progress and HTV 2 flights, one would need these so much more for the operation. On the other transport it the bulk of the fuel to the station needs and has all supply flights and the powerful driving gear for lifting the station. Amazingly, an ATV is judged not particularly expensive: warehousing A flight will cost about 300 million euros, about 6 times more than a Progress capsule, but with correspondingly more payload and also the prices of Russia warehousing are difficult to compare with Western (probably warehousing also a reason why many German companies in the former Eastern Bloc build). Only one of the modules, the HTV is also equipped for a very long operating time. Up to 6 months it is to remain in space. It has its own power supply, drive systems and can couple independently.
So it is not surprising that the ESA now prompted a number of studies, how one could use the ATV better. Finally, there is due to the failure of the shuttles a gap in transportation. Already in 2004 there were two initial studies. warehousing The first examined whether it would not replace the part of the ATV, which is pressurized by a part, which includes a capsule warehousing and is provided with a re-entry shield. Such technologies have been tested at the ARD. This "Largo Cargo Return" baptized Carrier shall return large amounts of cargo to the earth - this is currently not possible without the shuttle. This could also replace warehousing the racks aboard the station.
