Photos of SpaceX’s floating landing barge
The landing barge on which the first stage of the Falcon 9 attempted to land has returned to port.
Photos of the barge show signs of blast and burn damage to cargo containers and possible wreckage from the rocket covered by tarps on the platform’s deck. The rest of the vessel appeared undamaged.
These photos do not show as much wreckage as I would have expected, though my expectations here aren’t based on much knowledge. I would have thought that the first stage remains would have been more substantial.

Cruz and Rubio to chair important space and science subcommittees
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.

Elon Musk’s twitter explanation of the 1st stage landing attempt
Link here.
He says there were only “10% off”. I suspect that number is off the top of his head, but it does represent how close they came. They hit the barge, and the rocket was attempting to get into position for touchdown when fuel ran out. That is an amazing success for a first attempt of something that no one has ever tried before.

Opportunity reaches high point on crater rim
The Mars rover Opportunity has climbed to its highest Martian altitude yet, a point on the rim of Endeavour Crater 440 feet above the crater floor below.
This despite the rover’s continuing memory problems.

Dragon reaches orbit
Another successful Falcon 9 launch for SpaceX this morning, placing a Dragon capsule in the correct orbit for rendezvous and berthing with ISS.
We still await word on the attempt to land the first stage of the rocket on a barge in the Atlantic. From the link above: “SpaceX founder Elon Musk has tweeted an update: ‘Rocket made it to drone spaceport ship, but landed hard. Close, but no cigar this time. Bodes well for the future tho.'” More details here.
Based on what they have released, SpaceX has achieved something pretty incredible for its first attempt, actually hitting the floating ship at landing. That the landing itself was not soft or gently is literally only a detail. They will have the opportunity on future launches to get it right.

Falcon 9 launch rescheduled for Saturday
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.

Europe reconsiders reusability in its rockets
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 search for Philae goes on
Analysis of new data from Rosetta has still failed to locate Philae, though engineers are confident that sometime in May/June the sun will begin to charge its batteries so it turn back on and tell us where it is.

Chinese service module journeys to and from Moon
The competition heats up: The service module of China’s first lunar return capsule, launched and successfully returned to Earth in November, is returning to lunar orbit after journeying to L2 more than 35,000 miles from the Moon.
After testing its maneuvering ability at L2, engineers are now moving it back to lunar orbit for further tests.

Some details on the SpaceX’s attempt to land its Falcon 9 first stage
This SpaceX press release gives some good info on the difficulty they face getting the first stage on Tuesday’s Dragon launch to land successfully on its floating sea platform:
To complicate matters further, the landing site is limited in size and not entirely stationary. The autonomous spaceport drone ship is 300 by 100 feet, with wings that extend its width to 170 feet. While that may sound huge at first, to a Falcon 9 first stage coming from space, it seems very small. The legspan of the Falcon 9 first stage is about 70 feet and while the ship is equipped with powerful thrusters to help it stay in place, it is not actually anchored, so finding the bullseye becomes particularly tricky. During previous attempts, we could only expect a landing accuracy of within 10km. For this attempt, we’re targeting a landing accuracy of within 10 meters.
They are going to try however, and they will be filming their attempt all the way. Stay tuned for some very interesting footage.

Weather reports moderately favorable for Tuesday’s Falcon 9 launch
The weather for Tuesday morning’s SpaceX launch of Dragon/Falcon are presently 60% favorable.
If all goes right, SpaceX will also try to bring the first stage back to a vertical soft landing on a ocean-going platform. If they succeed, they will immediately revolutionize the entire space launch industry.

Memory problems on Mars rover Opportunity
After more than ten years of operation, the Mars rover Opportunity has been suffering increasing flash memory problems with its computer.
Engineers have pinpointed the issue to one of the rover’s seven memory banks, and hope to upload software that will force Opportunity to stop using that particular bank. If so, the rover shall live on.

Proton launches commercial satelite
The Proton rocket which had its launch delayed several weeks in order to repair a faulty gyroscope successfully placed a commercial satellite in orbit today.
Earlier this week there were also two successful Soyuz rockets. For Russia’s aerospace industry, 2014 has definitely ended the year on an up note.

A Russia/Brazil partnership for Sea Launch?
The competition heats up: Russia is negotiating a partnership with Brazil to operate Sea Launch.
The Sea Launch rocket is built by Ukraine, which presently has hostile relations with Russia, to say the least. The platform, built with Boeing money, is presently docked on the the U.S. west coast, which is also not what Russia wants. Moving it to Brazil and adapting it for use with a Brazilian rocket solves both problems, though the usability of Brazil’s rocket is at this moment quite questionable.

India’s Mangalyaan Mars probe working fine
After three months in orbit around Mars, India’s Mangalyaan spacecraft continues to function as designed, and is expected to operate beyond its planned six month mission.
In the last three months, Mangalyaan has captured nearly 300 pictures. On an average the spacecraft takes four pictures in three days. Besides capturing the images of dust storm activities, it has also taken images of comet Siding Spring.
Because of Mangalyaan’s orbit and the wide-angle nature of its camera the pictures are generally global. This output also is not spectacular compared to other probes. Nonetheless, this is an achievement for which India should be proud.

Loose fibers significantly cuts Gaia’s output
Europe’s Gaia telescope, designed to precisely measure the motions of a billion stars in the Milky Way, will have its accuracy cut in half because of the presence of loose fibers on the telescope’s sun shield that are allowing too much stray light in.
These fibres were spotted on Gaia before launch, but cutting them off was considered too risky, because that could allow small particles to enter the spacecraft. Another option, taping them down, was also ruled out because the increased stiffness could prevent the sunshield from unfolding.
The stray light shouldn’t affect measurements of the galaxy’s brightest stars, says Gaia science team member Anthony Brown at the Leiden Observatory in the Netherlands, but it will double the expected errors on most of the stars in the Milky Way, which are much fainter.
For astronomers this is a great tragedy. Gaia will still teach us much, just not as much as they had hoped.

Angara A5 rocket launches successfully
The competition heats up: Russia successfully completed the first test launch of the heavy-lift version of its Angara rocket today.
More background here.
At this moment the dummy payload is in a preliminary orbit and requires additional engine burns by the Briz-M upper stage to reach its planned geosynchronous orbit. Briz-M however is well tested and has been in use for years already on the Proton rocket. Therefore, for Angara this flight has now been a complete success, even if the Briz-M stage fails.

Successful Falcon 9 static fire
After unspecified issues on a static fire test last week caused the postponement of the Falcon 9/Dragon launch until January 6, SpaceX followed up with a successful full static fire test of the rocket on Friday.
SpaceX fueled up a Falcon 9 rocket, ran through a mock countdown and fired the booster’s nine Merlin main engines Friday in a successful preflight static fire test officials hope will clear the way for liftoff Jan. 6 on a space station resupply mission. The exercise occurred at approximately 2:55 p.m. EST (1955 GMT) Friday while the Falcon 9 rocket and a Dragon supply ship were kept grounded at Cape Canaveral’s Complex 40 launch pad.

Emailing a wrench to ISS
Having overheard an ISS astronaut mention the need for a particular type of wrench, the company that made the 3D printer on the station immediately worked up a design and emailed that to him, allowing him to print it up.
No word on whether the astronaut actually printed it, but it seems to me that he should do so immediately, then test its use.

Kepler reborn
Kepler detects its first exoplanet after its mission was reshaped because of the failure of two of its four gyros.
The newfound planet, HIP 116454b, has a diameter of 20,000 miles, two and a half times the size of Earth. HARPS-N showed that it weighs almost 12 times as much as Earth. This makes HIP 116454b a super-Earth, a class of planets that doesn’t exist in our solar system. The average density suggests that this planet is either a water world (composed of about three-fourths water and one-fourth rock) or a mini-Neptune with an extended, gaseous atmosphere.
This close-in planet circles its star once every 9.1 days at a distance of 8.4 million miles. Its host star is a type K orange dwarf slightly smaller and cooler than our sun. The system is 180 light-years from Earth in the constellation Pisces.
Even more cool, the detection took place during Kepler’s first test run in its new configuration. This bodes well for the space telescope’s ability to make future discoveries.

Falcon 9/Dragon launch rescheduled
SpaceX has rescheduled the launch of Dragon from Friday to no earlier than January 6.
The link notes that though SpaceX doubled its launch rate from 3 in 2013 to 6 in 2014, this was still half of what the company had planned. I suspect however that the launch rate will grow once again in 2015, and SpaceX continues to ramp up its operations.

India’s rocket and manned capsule test flight a success
The competition heats up: India has successfully completed both a test launch of the first stage of its upgraded GSLV rocket as well as the suborbital deployment and splashdown of a test manned capsule.
More details are sure to follow, but at the moment it appears that everything went exactly as planned.

Friday’s Falcon 9 launch delayed
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.
