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.
An evening pause: From the 1955 Jimmy Stewart film Strategic Air Command. The B-36, with both propeller and jet engines, was soon superseded, but the takeoff, as captured so well in the movie, is impressive. It was a big plane.

The monthly update by NOAA of the solar cycle, showing the sunspot activity for the Sun in December, was released this past weekend. As I do every month, I am posting it here, below the fold, with annotations to give it context.
Even though sunspot activity in December increased, the slow ramp down to solar minimum continues to track the 2009 prediction of the solar scientist community. The overall intensity of the solar maximum prior to 2014 was considerable less than this prediction, but the numbers throughout 2014 matched that prediction remarkably well.

The cartoon on the right prompted the first Islamic riots. More recent ones in the French magazine Charlie Hebdo apparently prompted today’s violent murders.
The goal of these Islamic acts of violence: To stop people from criticizing Islam.
My goal in publishing this cartoon: To defy these thugs and to encourage people to criticize Islam. In the past two decades we have seen nothing but violence, terrorism, death, and destruction from this Arabic religion, fed by hatred and bigotry of Jews and Christians. It is time to say so, bluntly.
If Muslims wish this criticism to stop, they need to do something about it themselves, as the President of Egypt has, instead of demanding others to shut up.
The religion of peace strikes again: Twelve people were murdered today by Islamic terrorists at a French satirical magazine.
The magazine, Charlie Hebdo, had published many cartoons making fun of religion. Fortunately, they were able to avoid the hoards of Jewish and Christian terrorists that tried to kill them.
In addition, a car bomb has exploded in front of a synagogue in the suburbs of Paris. Update: An accident unrelated to terrorism.
The Obama administration has been quick to act, condemning the attacks while once again insisting that Islam is “a peaceful religion.” That is a quote, today, by Obama’s own press secretary.
Make sure you read James Delingpole’s prediction of what will happen next as our leaders will do anything to avoid facing reality so they can continue to live in a fantasy world where Islam is our friend and it is the evil racism of the west that caused this tragedy.
In defiance of Islam’s effort to impose its will on us all, here is a link to some of the cartoons Charlie Hebdo previously published making fun of Islam. Click on it. Spread it around. Let’s have everyone see it!
The uncertainty of science: Fused droplets found in many places across the globe and theorized to have come from a comet major impact that caused a major climate change around 13,000 years ago have now been found to have instead come from common house fires.
Since the 1970s when the Walter Alvarez found evidence of an asteroid impact in the Yucatan that could have caused the dinosaur extinction 65 million years ago, planetary scientists have seen asteroid or comet impacts everywhere. After all, impacts are cool disasters that play well to television producers and funding agencies.
Read this story however. It describes some very solid scientific work that wipes out one one of those cool theories, replacing it with something quite mundane.
The Space Telescope Science Institute (STScI) that operates the Hubble Space Telescope yesterday released two spectacular new images at the January meeting of the American Astronomical Society.
They also announced new data from Hubble that suggests a major eruption had occurred at the center of the Milky Way about two million years ago.
Worlds without end: Astronomers have confirmed from Kepler data the existence of 8 new exoplanets, all capable of having liquid water on their surface, with two more like Earth than any previous discovery.
These findings nearly double the number of known planets in the habitable zone, but researchers are especially excited about two of the new exoplanets: Their size, location, and star type means they could be rocky planets like Earth — which means they could have evolved life as we recognize it.
One of the planets, Kepler-438b, is only 12 percent bigger than Earth in diameter. That means it’s quite likely a rocky planet. Scientists have given it a 70 percent chance. Kepler-442b is a bit bigger at around 33 percent larger than Earth, but still has a 60 percent chance of being rocky.
But while 438b hits the sweet spot in size, 442b has it beat when it comes to distance from the sun. Both planets orbit a small red dwarf star, cooler than Earth’s Sun, but they also orbit more closely. 438b gets 40 percent more light than Earth, which means it has around a 70 percent chance of being able to hold liquid water. But with 66 percent as much light as our own planet, 442b has a 97 percent chance of being in the habitable zone.
An evening pause: Hat tip Edward Thelen. As he wrote in an email to me, “Don’t let anyone tell you that science isn’t fun.”
The competition heats up: Pressured by SpaceX, Europe has restarted a research program into developing a reusable first stage to its rockets.
The headline is actually an overstatement. The European managers quoted in the article actually spend most of their time explaining why trying to reuse a rocket’s first stage makes no sense, but they feel forced to reluctantly look into it anyway because of what SpaceX is doing with its Falcon 9.
This story makes me think of two blacksmiths around 1900. One poo-poos cars, saying that the repair cost is so high no one will ever buy them. He goes back to pounding horseshoes. The other decides that if he learns how to fix cars, he can turn his shop from fixing horseshoes to fixing cars, and make more money. Europe is the first blacksmith, while SpaceX is the second.
Which do you think is going to succeed?
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.
