ATV burns up, Progress launched

Busy day for travel to and from ISS: The European unmanned ATV freighter Johannes Kepler burned up in the atmosphere even as a Russian Progress freighter was launched.

In related news, the U.S. and ESA are in negotiations to merge the European unmanned ATV freighter program with NASA’s manned Orion derivative. At the same time, Europe has announced its plans to test fly a reusable space plane.

NASA about to decide on its shuttle heavy-lift replacement

NASA is about to decide on its shuttle heavy-lift replacement, and it looks like it will be almost entirely shuttle-derived.

As I have said previously, this rocket will almost certainly never fly. NASA has to start over after spending billions and years developing Constellation, and is being given less money and time to do it.

And even if I am wrong and this rocket does fly, I bet it will do only one flight and then be retired as too costly.

ESA controllers buy time to solve problems on comet probe Rosetta

This ain’t good. One of the reasons ESA controllers recently put the comet probe Rosetta into hibernation for two and a half years was in order to buy time to solve a serious technical problem.

Mission managers said the hibernation will permit Rosetta to rest its four reaction wheels, two of which have shown signs of degradation. The satellite needs three to function, and one of the two problem wheels will be used only as a spare when the satellite is awakened in January 2014 in preparation for its approach to a comet.

Second X-51 hypersonic flight crashes prematurely

Second X-51 hypersonic flight crashes prematurely.

After what the US Air Force described as a ‘flawless’ flight to the launch point aboard a Boeing B-52 mothership, the X-51 was successfully boosted to Mach 5.0 by a rocket booster. The Pratt & Whitney Rocketdyne scramjet engine successfully ignited using its initial fuel, ethylene. During the immediate transition to JP-7, the conventional fuel that makes the X-51 unique, an inlet unstart occurred. A subsequent attempt to restart and reorient to optimal conditions was unsuccessful.
