SpaceX has positioned recovery crews in the Atlantic in an effort to retrieve the Falcon 9 first stage after its upcoming launch, now set for Friday.
Today’s launch of Dragon to ISS has been scrubbed due to “a helium leak in Falcon 9’s first stage.”
SpaceX also says they will be ready to launch by April 18, their next launch window.
A fire at a radar site used by the Air Force to track rockets lifting off at the Kennedy Space Center has delayed all launches there, including SpaceX’s next Falcon 9 flight.
Initially the Air Force thought they could make repairs relatively quick, but now think it could take as long as 45 days. No new launch date for the Falcon 9/Dragon flight as yet been set.
The contamination that has delayed SpaceX’s next Dragon cargo mission to ISS was caused by oil from a sewing machine.
The machine sewed the cloth blankets that protect payloads in Dragon’s unpressurized trunk section.
According to the former CEO of Arianespace, now head of the French space agency, SpaceX’s Falcon 9 costs significantly less to launch than the Ariane 5.
How big is the difference? Jean-Yves Le Gall, who until mid-2013 was chief executive of Evry, France-based Arianespace and is now president of the French space agency, CNES, addressed the point in Feb. 25 testimony to the French Senate. According to Le Gall, launching a satellite on an Ariane 5 costs around 100 million euros ($137 million). After subtracting the amount of European Space Agency subsidies to Arianespace, the per-satellite cost drops to about $100 million, he said.
Hawthorne, Calif.-based SpaceX, he said, would charge $60 million to $70 million to launch the same satellite aboard the Falcon 9. In fact SpaceX has charged even less than that to its first few commercial customers.
It is for this reason that Arianespace is struggling to decide how to build its next generation rocket. They have find a way to do it cheaper, something that is very difficult for this multi-headed European conglomerate to do.
The next Dragon launch to ISS has been delayed for two weeks because of the detection of contamination that could affect some of its research cargo.
[T]he launch was put on hold, sources said, when engineers noticed contamination of some sort on the Dragon’s lower unpressurized trunk section. Two of six electrically powered payloads aboard the Dragon are mounted in the trunk section — a first for this mission — and engineers were concerned the contamination might “outgas” in orbit and cause problems for the station-bound hardware.
On Saturday SpaceX successfully conducted a dress rehearsal countdown and static fire engine test of the Falcon 9 rocket that will loft a Dragon capsule to ISS next week.
The results of the test itself have not been released, but that it was completed suggests all is well for the upcoming launch.
A static fire engine test of the Falcon 9 scheduled to lift Dragon to ISS next week has been delayed one day.
The article gives no explanation for the delay.
Returning the Falcon 9 first stage safely: More details about the next attempt during the next Dragon launch to ISS on March 16.
Not only will this test do more engine burns, they will attempt the first deployment of the stage’s landing legs. The article also gives more details about the last launch test, as well as the Grasshopper tests.

It is now confirmed that the next Falcon 9 launch to ISS will have legs on its first stage and will attempt a controlled landing over water.
Earlier reports were based on rumors and unofficial reports.
The competition heats up: The next Falcon 9/Dragon launch to ISS will include the first test of legs on the rocket’s first stage, as well as an attempt to complete a soft touchdown on water of that first stage.
The article is chock full of interesting details about SpaceX’s effort to make the first stage of the Falcon 9 reusable.
Posted from Garden City, New York.
For a variety of reasons, SpaceX and NASA have agreed to delay the next Dragon cargo mission a few weeks to no early than March 16.
It looks like it was a combination of minor issues that, when piled up, called for a delay.
