Europe's Automated Cargo Shuttle Docks With Space Station 108
An anonymous reader writes "A successful docking of the Automated Transfer Vehicle dubbed 'Jules Verne' occurred earlier this week. The first of its kind, the crewless ship reached orbit and lightly touched up against the international space station on Thursday. By now astronauts on the ISS will have opened its doors and begun air circulation in preparation of offloading the nearly 7.5 tons of fuel, oxygen, food, clothing and equipment they need to survive. The EU Space Agency sees this as a historic journey for the program: 'The Jules Verne, named after the visionary French science fiction author, is the first of a new class of station supply ships called Automatic Transfer Vehicles. The craft was built by the nations of the European Space Agency as one of Europe's major contributions to the international station. "The docking of the A.T.V. is a new and spectacular step in the demonstration of European capabilities on the international scene of space exploration," said Jean-Jacques Dordain, director general of the European Space Agency.'"

IIRC, so far the Russians have been lifting the majority of supplies to the station, because the Shuttle hasn't been going up regularly. Not to mention they've been getting paid but the USA for the privilege.

Only Russia has previously achieved a successful automated docking in space, Dr. Griffin said in a statement.
I wonder what kind of system the Russians were using and are still using? It took this long for others to catch up and, from the article once again, they had to use GPS and other systems. I'm sure the Russians had it much simpler.

Kindly separate what some inaccurate media summary says and what the ESA itself states. Where exactly does ESA claim to have "the first automated transport spacecraft?". They say it is the first of its kind, i.e. one that navigates and docks fully automatically, which is neither a lie nor an overstatement. And quoting from the Smart-1 (probe with ion drive) site:
I haven't bothered checking your "first 3-axis stabilized spacecraft to be operated without any gyro" example but frankly I'm sure I'd not find an "outright lie" here or even a overstatement either.

The New York Times article states:

And it definitely is a new class of suplly ships.
You should not bash an organization based on the wording of an anonymous Slashdot submission of an article which does not even contain this phrase.

Read Bate, Mueller, & White, "Fundamentals of Astrodynamics", (Dover Books). (Caution: Math required.)
Imagine two coplanar circular rings, of very slightly different diameter, with a common center. They're concentric. Tilt one slightly with respect to the other, retaining the common centering. The rings now cross at two diametrically opposed points.
Those rings represent non-coplanar orbits. Objects traveling along the two orbits appear to be in parallel course at widest separation, then they start coming together, collide, and start moving apart again.
The cheap way to do rendezvous is get the two spacecraft onto the SAME orbit, with some separation, and then GRADUALLY maneuver one of them to bring it closer. It is extremely touchy work. (This is why Project Gemini spent so much time learning how to rendezvous the Gemini spacecraft with the Agena target: they had to be able to do rendezvous to do the Apollo moon landings.)
Read "Carrying the Fire", by Mike Collins, for some interesting insight into the problem. (Mike Collins was Apollo XI Command Module Pilot.)

Um, no. NASA was ordered to do the big bang project by the Kennedy and subsequent Administrations. NASA originally planned to go to the moon possibly sometime in the 70's, maybe.
Um, no. Of the landing sequence NASA planned (through Apollo 20), two flights (what would have been 15 and 19) were cut in 1967 and the the third (what would have been 17) in early 1969 - before any landings had occurred.
There are no gaps in the as-flown sequence because NASA renumbered the remaining missions. The cuts occurred as long lead items were being procured and before any serious mission planning was done.
Um, no. When asked for a post-Apollo roadmap and budget, despite the steep budget cuts of 1967-69, NASA asked for the whole [expensive] ball of wax - a Shuttle, a Station, and serious seed money for a permanent lunar base and a Mars expedition. When the Administration made it clear to NASA just how limited their budget was going to be, they made the only natural choice - to ask for funding for the first step of Von Braun Vision, a shuttle. (The grandparent has the shuttle-station order reversed.) NASA has remained hopeful essentially ever since that the blank check years would return - a misbegotten pipe dream that continually badly warped NASA planning.
It surprises many people to learn that the basic contracts for the Shuttle were signed on July 21, 1969 - while Apollo 11 was on the moon, the death warrant for the Apollo program had already been signed (Saturn V production having been capped two years previously by Congress) and its successor was being born.
