Mold forces Cygnus launch delay

The discovery of mold in two clothing bags being packed for a Cygnus freighter launch to ISS has caused NASA to delay the launch by at least two weeks.

The source of the mold, a common fungal growth in humid climates like Florida’s, is under investigation by NASA and Lockheed Martin, which prepares NASA cargo for launch aboard two commercial carriers, Orbital ATK and privately owned SpaceX. An Orbital Cygnus cargo ship was more than halfway packed for the launch, scheduled for March 10, when the mold was found during routine inspections and microbial sampling, NASA spokesman Daniel Huot said.

The mold did not present any serious health threat should it have arrived at ISS, but it is definitely preferred to not fly it there if possible.

SpaceX to reduces chance of first stage recovery on SES-9 launch

In the heat of competition: Because of SpaceX’s delays in launching the SES-9 communications satellite, the company has modified the launch profile of its Falcon 9 rocket, abandoning a land vertical landing and reducing the odds for a successful barge landing, in order to get the satellite to its proper orbit sooner.

SES will thus be able to generate income from the satellite at about the same time it would have had their launch not been delayed. SpaceX meanwhile will still try to recover the first stage, but will face much more difficult odds.

One industry official familiar with the SES-9 mission said Hawthorne, California-based SpaceX has not abandoned hope of recovering the first stage after a landing on an offshore platform positioned for the mission. But the chances of success are much less given the launch trajectory agreed to with SES to reduce the time to arrival at its operating position.

Marlene Dietrich – Lili Marleen

An evening pause: The song, aired initially during World War II by the Nazis for their troops, became a popular hit for soldiers on both sides of the war. Marlene Dietrich then recorded it as part of her effort to win the war for the Allies, in both English and German. She noted once that the German version is “darker”. Here is the English version.

Hat tip Engine Mike.

Next Falcon 9 launch date announced

In the heat of competition: SpaceX and SES have announced that they are aiming for a February 24 date for the launch of the SES-9 communications satellite.

This will be the second launch of the upgraded Falcon 9, delayed since December following that rocket’s first launch. That they have scheduled it means they have likely smoothed out the kinks detected on that first flight.

Experts: NASA’s SLS Mars proposals bunk

The death of SLS begins: At House hearings this week, congressmen listened to several space experts who lambasted NASA’s asteroid and Mars mission proposals.

Paul Spudis of the Lunar and Planetary Institute and an expert on lunar science, was especially harsh.

โ€œAmericaโ€™s civil space program is in disarray, with many aspirations and hopes but few concrete, realizable plans for future missions or strategic direction,โ€ he said, adding that NASA lacks what it needs to pull off the mission (and throwing some shade at the agencyโ€™s strong Twitter game). “We pretend that we are on a ‘#JourneytoMars’ but in fact, possess neither the technology nor the economic resources necessary to undertake a human Mars mission now or within the foreseeable future. What is needed is a logically arranged set of short-term, realizable space goalsโ€“a series of objectives and destinations that are not only interesting in and of themselves, but whose attainment build space faring capability in the long term.”

The testimony claimed that it could cost anywhere from $500 billion to $1 trillion for NASA to get humans to Mars, numbers that are reasonable based on using NASA’s very costly and overpriced SLS/Orion rocket and capsule. The congressmen were of course interested in this, not because they want to get to Mars, but because they see gobs of pork for their districts in these numbers.

However, I expect that when SpaceX begins successfully launching its Falcon Heavy rocket in the next two years while simultaneously putting humans in space with its Dragon capsule, and does both for a tenth the cost of SLS/Orion, those same congressmen will dump SLS/Orion very quickly. Though they want the pork, they also know they don’t have $500 billion to $1 trillion to spend on space. The private sector gives them an option that is both affordable and of strong self-interest. The more realistically priced and designed hardware of private companies will give them a more credible opportunity to fund pork in their districts.

SpaceX promises increase in Falcon 9 launch rate

The competition heats up: Even as SpaceX upgrades its Falcon 9 rocket as a result of tests of the returned first stage, the company said this week that it plans to increase its production and launch rate significantly in 2016.

“Weโ€™ve had the luxury in years past of having to build only a few rockets a year,โ€ [Company official Gwynne Shotwell] said, โ€œso we really werenโ€™t in a production mode.โ€ Last year would have been the first to require a high production rate of the rocket, she said, had it not been for the June launch failure that halted flights for nearly six months. โ€œNow weโ€™re in this factory transformation to go from building six or eight a year to about 18 cores a year. By the end of this year we should be at over 30 cores per year,โ€ she said. โ€œSo you see the factory start to morph.โ€

Those changes, she said, include doubling the number of first stages that can be assembled at one time from three to six. The company is also working to accelerate production of the Merlin engines that power the Falcon 9 since, at the higher production rates planned for this year, the company will need to build hundreds of engines a year.

She also said that they hope to reach a cadence of a launch every two to three weeks.

We shall see. While I have confidence in SpaceX’s ultimate ability to achieve these promises, much can change as they ramp up their effort. For example, Shotwell noted that they had hoped to achieve this launch rate in 2015, but were stopped after the June launch failure.

Falcon 9 to be modified

The competition heats up: SpaceX is modifying its Falcon 9 rocket based on engine tests it performed on the December 22 returned first stage.

SpaceX will be making modifications to its Falcon 9 rocket based on what the company learned from re-igniting the engines on the vehicle it landed. That’s according to SpaceX president Gwynne Shotwell, who spoke about the state of the company today at the Commercial Space Transportation Conference in Wasington, DC. Shotwell didn’t specify what those modifications will be, but said the changes will make the vehicle “even more robust” for its ascent into space.

This report helps explain why SpaceX has pushed back all planned launches of the upgraded Falcon 9 rocket. Their tests of the returned first stage revealed issues that they think are important enough to be addressed before another rocket is launched, and they are proceeding to deal with those issues.

It also illustrates an enormous advantage they have over every other rocket company that has ever existed in the past. They, unlike all past rocket companies, actually have a used first stage that they can study to see the real consequences of launch and landing. All previous estimates of those consequences were only based on computer models and speculation.
