A false alarm on ISS early this morning, signaling the leak of ammonia coolant, forced the evacuation of the American portion of ISS.
American engineers are assessing the cause of the alarm, though they seem pretty confident now said that no leak of any ammonia took place and the problem was likely caused by a faulty sensor.
Update: The crew has now returned to ISS.
We are about to find out how conservative and pro-private enterprise senators Ted Cruz (R-Texas) and Marco Rubio (R-Florida) really are. Both have been assigned as chairmen of important subcommittees managing NASA and NOAA.
Cruz will chair the subcommittee on Space, Science, and Competitiveness, which handles NASA, while Rubio will chair the subcommittee that handles NOAA.
For Cruz especially this position will challenge him to prove his tea party credentials. If he is in favor of private space as much as he claims, we will see him work to trim SLS, a pork project with no hope of achieving anything in space, and favor the commercial space effort, even though SLS brings much more pork into his state.
NASA has produced retro-style travel posters for three alien exoplanets which you can download and print.
The posters are quite cool, which is not surprising, considering that, in the past four decades, the best interplanetary travel that NASA has been able to achieve has been its graphic power-point and pr images. Unfortunately, for NASA actually going there has not been so easy.
SpaceX and NASA have now rescheduled the Falcon 9/Dragon launch to ISS for Saturday morning at 4:47 am Eastern.
I am wondering if lack of light is going to effect the effort to vertically land the first stage.
The GAO has ruled against Sierra Nevada’s protest of NASA’s decision to pick Boeing for its manned spacecraft decision.
The ruling is not really a surprise. Even if political considerations gave Boeing an unfair advantage, the space agency has enough legal leeway to make this decision as it did. The GAO recognized that it would be inappropriate to overrule them.
Due to issues in the rocket’s steering system this morning’s Falcon 9/Dragon launch was scrubbed.
They will try again Friday morning at 5:09 am Eastern.
Despite a decade of development, including the production of two satellites, the Orbiting Carbon Observatory-2 was launched in July with a basic design flaw that was never spotted.
Scientists and engineers on the project have ridden an emotional roller coaster. In 2009, a rocket failure doomed the Orbiting Carbon Observatory, their first attempt at a carbon-mapping probe. Its replacement, OCO-2, launched successfully. But after the JPL turned on the main instrument — a trio of spectrometers that measure sunlight light reflecting off Earth’s surface — the team discovered a problem in OCO-2’s data. They eventually determined that it was caused by a design flaw that reduced the amount of light entering the instrument during one mode of operation. The problem dated to 2004 and had never been caught in testing, says JPL’s David Crisp, the science team leader of the OCO-2 mission. “It was a stupid mistake. Embarrassing to the instrument designer and to me,” he says.
This flaw was apparently in both OCO satellites and was never noticed.
Fortunately, they have improvised a work-around that is allowing the spacecraft to get its data, which interestingly shows the highest concentrations of CO2 are coming not from the U.S. and the First World but from poorer parts of Africa and South America (caused by “burning savannas and forests,” not SUVs) and from China.
Because of a scrubbed static fire test on Tuesday, it is now likely that Friday’s Falcon 9/Dragon launch will be delayed until January.
Attempts during the four hour test window on Tuesday did not result in a successfully conducted Static Fire. Several requests for further information, sent to SpaceX during and after the test window, resulted in the company saying they had no information to provide. SpaceX normally provide confirmation after a successful conclusion to the test.
Source information noted at least one full countdown towards the firing was attempted, which was classed as aborted at the very end of the count. At least one NASA-based outlet claimed the Static Fire had taken place, potentially pointing to ignition of the Merlin 1D engines, before an abort – due to an issue – was likely called. No confirmed information on the issue has been forthcoming from SpaceX. However, the company has promised to provide more information to this site when “they have something to share.”
It was, however, understood that the next Static Fire attempt is likely to take place no sooner than Thursday. That too appears to have been cancelled following review.
If tomorrow’s static fire test has been canceled then Friday’s launch will definitely be canceled as well. None of this has been confirmed yet, however, so it is possible that all is well and the launch will go forward as planned.
Update: The launch delay has now been confirmed. A new launch has not yet been announced however.

SLS marches on! Though Obama cancelled the Constellation rocket program in 2010, NASA continued to build a $349 million engine test stand for that rocket, finishing the tower in June 2014.
The test stand was also significantly over budget. It now sits useless, since the SLS rocket will use a different untested engine in its upper stage during its first manned flight.
It is every important to underline the chronology here. The rocket was cancelled in 2010. Construction on the test stand continued however for four more years, partly because of decisions by NASA management and partly because of mandates forced on them by Congress.
Stories like this illustrate why I think the political clout of SLS is weak. The program is too expensive, is riddled with waste, and it can’t accomplish anything anyway, making it a perfect target for both muckraking journalists and elected officials who want to make a name for themselves saving the taxpayer’s money. And both have a perfect inexpensive and successful alternative to turn to: private space.
The final scheduled testing of the cryogenic cooler required to cool one instrument on the James Webb Space Telescope has been repeatedly delayed, from its original date of January 2014 to anywhere between April to November 2015.
The cost for this particular instrument has also ballooned since the contract was first awarded, more than doubling.
For reasons that are unclear NASA and SpaceX have delayed the launch of the next Dragon cargo flight to ISS for three days.
The only reasons stated were that they wanted to insure that everything was ready on the launchpad.
