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.
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.
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 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?
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.
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.
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.
Want to work for SpaceX? You can! They are now posting job openings for those who want to work at their new spaceport in Brownsville Texas.
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.
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.
The competition heats up: 2014 saw the highest number of rocket launches in two decades.
Russia led the way with the most launches, as has been typical.
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.
With its arrival set for March, the space probe Dawn has now officially begun its approach to Ceres, the largest asteroid in the asteroid belt.
The competition heats up: In an interview today Russia’s deputy prime minister said that the construction of Vostochny is back on schedule and should be completed as planned in July.
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.
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.
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.
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.
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.
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.
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.
The Rosetta team has released a gif movie of Comet 67P/C-G, created by compiling images taken over a period of two weeks in late November.
The movie shows the nucleus’s rotation during that period, which helps viewers understand better its geography.
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.
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.
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.
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.
Link here. The launch is scheduled for 11 pm Eastern tonight.
Thursday’s test launch will check the performance of the GSLV Mk. 3’s first stage and strap-on boosters, which will carry the rocket out of the atmosphere beyond the boundary of space. The launcher’s cryogenic upper stage, which will be active and fueled by liquid hydrogen on future missions, will be dormant on Thursday’s flight.
…After the rocket’s propulsion shuts down, a gumdrop-shaped capsule will separate from the GSLV Mk. 3’s dummy upper segment about five-and-a-half minutes after liftoff, according to the Times of India, another English-language paper in India. The capsule weighs about 8,000 pounds — about 3.6 metric tons. Indian engineers from Hindustan Aeronautics Ltd. fabricated the car-sized module, and ISRO added sensors, strain gauges, a guidance and control system and a heat shield for the suborbital flight, which is called the Crew Module Atmospheric Re-entry Experiment, or CARE.
Google has extended the deadline for its Lunar X-Prize, giving the 18 contestants until the end of 2016 to launch a rover to the Moon. One company immediately delayed its planned launch.
Meanwhile, the Kickstarter campaign of one of the contestants has reached its fund-raising goal of $1 million, well ahead of its deadline.
Thar’s black gold up thar! Data from Cassini has confirmed the presence of ocean waves on Titan’s seas, while also providing suggesting that they are made mostly of liquid methane, not ethane as had been predicted.
The maximum depth of Kraken Mare appears to be 160 meters, and Ligeia Mare could be as much as 200 meters deep, reported Marco Mastrogiuseppe of Sapienza University of Rome. The fact that the radar signals could bounce off the sea bottom suggests that the seas were more transparent than expected and thus must contain mostly methane, not ethane. Hayes says his best estimate is about 90% methane. Essam Marouf, a planetary scientist at San José State University in California, reported on the first results from a separate radar experiment that sent radar reflections to Earth instead of back to the spacecraft. Those tests provide independent evidence that the seas are dominated by methane, Marouf says, and it implies that the lakes are kept filled by precipitating methane.
As the article also notes, this methane is “55 times Earth’s oil reserves.”

At the heart of the latest plan is the botched construction of the Multi-purpose Laboratory Module, MLM, the Russia’s next big piece of the International Space Station, ISS. After many years of delays, the price tag for the MLM project ballooned to one billion rubles, however the all-but-completed module had to be grounded until at least 2017 due to severe quality control problems during its manufacturing at GKNPTs Khrunichev in Moscow. Repairs of the module were estimated at another billion rubles and GKNPTs Khrunichev was expected to cover this cost from its own reserves. However, the nearly bankrupt company came back with an announcement that it already owed around a billion Euro and would not be able to pay for the future work. Even if repaired and successfully launched, the MLM module, which would have taken more than two decades to build, could arrive at the ISS on the eve of its retirement.
As an alternative, Russian space officials came up with a new scheme to build a whole new station around the MLM, instead of launching it to the ISS. The project with an estimated price tag from four to five billion rubles would cover a five-year delay in the construction of the ISS. The new Russian station would also utilize all future Russian modules, which were expected to follow MLM to the ISS, such as the Node Module, UM; the Science and Power Module, NEM; an Inflatable Habitat, and the OKA-T laboratory.
There’s more. Read it all.
