NASA engineers have successfully fixed the glitch on the LADEE spacecraft.
Having completed its investigation into its scrubbed launch two weeks ago, Japan’s space agency JAXA has announced a September 14 launch date for its new Epsilon rocket.
The first and second launch of the Space Launch System are likely to be delayed due to budget issues.
“It’s very clear that we could have slips of a year or two,” said [deputy administrator Lori] Garver, referring to both the 2017 launch — which won’t have a crew — and the first planned flight of NASA astronauts aboard the SLS rocket in 2021.
Garver claims that it is insufficient funds for SLS that will cause the delays, despite getting $3 billion per year, or ten times the money the private commercial program is getting.
I’m on a hike today, but so any additional comments about this insanity will have to wait.
NASA’s lunar probe LADEE was successfully launched tonight from Wallops Island.
Update: A computer glitch occurred shortly after reaching orbit, causing the computer to shut down the spacecraft’s reaction wheels.
Engineers seem unworried, and expect to have the problem solved within a couple of days.
The competition heats up: The Russians are including a bathroom in their next generation manned vehicle, something they note Orion will not have.
A new Russian spaceship for trips to the moon or the International Space Station will have at least one crucial advantage over its American rival – a toilet, one of the craft’s developers said Friday. “I don’t think I need to elaborate on how a waste-collection system is much more comfortable than the diapers that astronauts aboard the [US spacecraft] Orion will have to use,” said Vladimir Pirozhkov of the Moscow Institute of Steel and Alloys, which is involved in the development of the Russian ship. “Besides, the Russian segment of the International Space Station [ISS] has a limited number of toilets, which means a spacecraft with an extra ‘space toilet’ will come in handy,” he added.
As much as I am skeptical of Orion and SLS, I am equally skeptical of the Russian claims of a next generation manned spacecraft. They have been unveiling these proposals now for more than a decade, with nothing ever getting built. With Orion we at least have an existing capsule, even if its bulkhead needed to fixed.
Though I will agree with them on one point: Putting a toilet on a vehicle intended to go beyond Earth orbit, which Orion is supposed to be designed to do, makes common sense. That NASA didn’t include this essential item in Orion reveals to us the unseriousness of the spacecraft.
The competition heats up: Orbital Sciences has now mated the Cygnus capsule to its Antares rocket for its September 17 launch to ISS. With photos.
The competition heats up: While the launch industry eagerly awaits SpaceX’s first commercial Falcon 9 launch on September 10, Arianespace has been signing up customers.
Arianespace Chief Executive Stephane Israel said Aug. 29 after the last Ariane 5 launch that the company has booked around 300 million euros ($400 million) in new orders in recent weeks, bringing this year’s total contract volume to 1 billion euros. Industry officials said the contracts are for government missions in Brazil and Japan, and commercial operators in Brazil, the United States, Mexico and Spain.
The Ariane 5 is incredibly reliable, having successfully completed more than fifty launches in a row. It is also much more expensive that Falcon 9, which is expected to cost a customer about half as much to get a payload into orbit.
Until SpaceX proves Falcon 9, Arianespace will be in a strong position to get customers. Once Falcon 9 starts flying regularly however, Arianespace will begin to lose business to this cheaper alternative. Thus, the new contracts will help tide the company over while they scramble to figure out how to reduce costs in order to compete.
In related news, SpaceX readies the new upgraded Falcon 9 for launch.
A engineering problem during construction of one of the shuttle-derived solid rocket boosters for SLS is causing delays.
[The] original test target of mid-2013 slipped when an issue with the aft segment [of the booster] was found. Inspection of the segment showed it was contained an area where propellant had debonded from the inside of the segment wall. Following analysis – which notably found no voids in the propellant itself – NASA decided to ask ATK to scrap the segment and cast a replacement.
Preparations … continued, with the shipping and integration of forward and center segments at the test site, while ATK went to work to replace the aft segment, following approval – post investigation – from NASA’s Marshall Space Flight Center. After ATK successfully cast the replacement segment in July, technicians carried out routine ultrasound and x-ray tests. Unfortunately, the tests showed this segment had also had similar voids. [emphasis mine.]
The Space Launch System (SLS), was mandated by Congress to use as much shuttle-derived components as possible in order to supposedly save money as well as employ as many of the companies that built those components as possible. In reality, however, every one of those components has required significant redesign to make them work in SLS. In the case of the solid rocket boosters, the four segment shuttle boosters were not powerful enough. They had to be expanded to five segments.
Moreover, it appears from this article it was other technically unnecessary changes to the boosters that are now causing this problem.

The competition heats up: NASA has put Orbital Sciences on notice that, assuming its demo cargo mission to ISS in two weeks is a success, the company might have to do it again as soon as December.
SpaceX is supposed to fly its next cargo mission first, but NASA thinks that flight will be delayed because of development issues with the upgraded Falcon 9 rocket.
NASA has lost contact with its Deep Impact probe and is racing against time to save it.
The competition heats up: SpaceShipTwo is expected to make its second powered test flight today.
Update: The flight was a success. More details from Virgin Galactic here.

The competition heats up: Orbital Sciences prepares its Cygnus capsule for its first flight to ISS, set for launch on September 17.
Orbital officials said the Cygnus spacecraft was scheduled to be attached to the upper stage of the Antares launcher Wednesday. Final cargo loading into the Cygnus spacecraft’s pressurized module is set for Saturday, followed by its enclosure inside the rocket’s 12.8-foot-diameter payload fairing.
Rollout of the Antares rocket from its horizontal integration facility to the launch pad one mile away is expected Sept. 13.
September will be a busy and important month for private space. We also will have SpaceX’s first commercial launch with its Falcon 9 rocket. If both are successful, the trend away from a big government space programs shall accelerate.
How to view the east coast launch on Septembert 6 of LADEE.
LADEE will attempt to solve the leftover question from the Apollo-era: Does the surface dust on the Moon levitate? The question is real, and the consequences could be significant for future lunar settlements.
Despite the astronauts’ success on ISS in recreating the spacesuit water leak, NASA engineers still do not know its cause.
What is unstated about this problem is that, because we used to have a big space shuttle with lots of cargo capacity, the American spacesuit was designed to be maintained and repaired on the ground. In the past the next space shuttle flight would have brought a new spacesuit to the station while taking this defective suit back to Earth for analysis and repair. Now that we don’t have a big space shuttle, our complex spacesuits are far more difficult to troubleshoot.
The solution? First, keep it simple. The Russians, limited by the capacity of their Progress and Soyuz capsules, made their Orlan spacesuit very simple and easy to use.
Second, get as many redundant replacements of the shuttle operating as soon as possible.
A London university has digitized and placed online a collection of historic space images.
I don’t think the press release’s claim that these images have never been online before is true for all the images. Nonetheless, the online availability especially of the Russian Venus images is very welcome.
A NASA veteran slams the Space Launch System (SLS).
The problem with the SLS is that it’s so big that makes it very expensive. It’s very expensive to design, it’s very expensive to develop. When they actually begin to develop it, the budget is going to go haywire. They’re going to have all kinds of technical and development issues crop up, which will drive the development costs up. Then there are the operating costs of that beast, which will eat NASA alive if they get there. They’re not going to be able to fly it more than once a year, if that, because they don’t have the budget to do it. So what you’ve got is a beast of a rocket, that would give you all of this capability, which you can’t build because you don’t have the money to build it in the first place, and you can’t operate it if you had it.
Q: What do you see as the alternative?
A: In the private sector we’ve got an Atlas and a Delta rocket, and the Europeans have a rocket called the Ariane. The Russians have lots of rockets, which are very reliable, and they get reliable by using them. And that’s something the SLS will never have. Never. Because you can’t afford to launch it that many times.
The Russian way: In an effort to deal with their quality control problems the Russians plan to consolidate their space industries into a single company controlled by the government.
This is not a good sign for the future competitiveness of the Russian aerospace industry. Consolidation will only reduce competition and innovation, while placing the government in control will only increase bureaucracy.
The launch date for India’s GSLV rocket has been pushed off until December in order to thoroughly investigate what caused the fuel leak during the scrubbed launch last week.
Curiosity makes a three frame movie of Phobos eclipsing the Sun.
The competition heats up? An Iranian news release today says that researchers at a local university have “designed and built” a manned spacecraft.
Sounds very dubious to me. I suspect what really happened is that these Iranian university researchers did some work outlining their proposed design, and this has now been translated into a “built” spacecraft.
More details are released about the launch abort of Japan’s new Epsilon rocket earlier this week.
For the first time since arriving on Mars engineers have allowed Curiosity to drive itself.
The 1-ton Curiosity rover used autonomous navigation for the first time on Tuesday (Aug. 27), driving itself onto a patch of ground that its handlers had not vetted in advance. The robot will likely employ this “autonav” capability more and more as it continues the long trek toward the base of Mars’ huge Mount Sharp, NASA officials said.
In autonav mode, Curiosity analyzes photos it takes during a drive to map out a safe route forward. The car-size rover used this ability on Tuesday to find its way across a small depression whose fine-scale features were hidden from Curiosity’s previous location.
The competition heats up: China’s first unmanned lunar lander is now scheduled for launch before the end of the year.
This mission is the second stage in their long term plans for unmanned lunar exploration. It began with an orbiter which mapped the surface in high detail, followed now by a lander, which will then be followed by a sample return mission.
It appears a programming error might have caused the scrub of Japan’s new Epsilon rocket launch yesterday.
The computer controlling the launch from the ground detected an abnormality in the rocket position but it was later found to be normal. “It may have been an elementary, but not serious, problem, ” said one of the experts, quoted by the Kyodo News agency. An inspection after the canceled launch found no abnormality with the attitude sensors mounted on the rocket or with the computer feeding the data to the ground, according to the Japan Aerospace Exploration Agency (JAXA).
This is a preliminary report, but sounds credible. The report also suggests that the Japanese are in no immediate hurry to launch but instead want to very carefully investigate the issue first. And as I said yesterday, this is really all good news for this new rocket.
Astronauts on ISS have successfully recreated the water leak in the defective spacesuit that almost drowned an astronaut last month.
They now have a very good idea of the components that caused the failure, and will be able to replace these with new parts. The next step will be to test the suit under the same conditions with the new parts.
The Falcon 9 launch of Canada’s Cassiope space probe has been rescheduled from September 5 to September 10.
No details yet for why the reschedule.
The competition heats up: A FAA waiver granted to SpaceX for its next launch outlines the details of the company’s effort to recover the first stage for reuse.
The first stage will coast after stage separation, and then perform an experimental burn with three engines to reduce the entry velocity just prior to entry. Prior to landing in the water, it will perform a second experimental burn with one engine to impact the water with minimal velocity. The second stage will coast and then perform an experimental burn to depletion.
Elon Musk has said that they will be experimenting with bringing the first stage back safely with each launch of the upgraded Falcon 9 rocket. This waiver now gives us the plan for the first launch. It also shows that they are also considering recovery of the second stage as well.
More water on the Moon: Scientists using data from India’s Chandrayaan-1 space probe have detected new evidence of water inside one lunar crater.
What makes this detection important is that this particular water was not placed there by the solar wind or asteroids. Its chemistry suggests it seeped upward from deep within the Moon’s interior.
Engineers in India have decided to completely replace the leaking second stage engine of the GSLV rocket whose launch was scrubbed last week.
The GSLV is a three-stage launch vehicle with four strap-on motors hugging the first stage. The first stage is powered by solid fuel while the four strap-on motors and the second stage are powered by liquid fuel. The third is the cryogenic engine powered by liquid hydrogen and liquid oxygen.
“At the rocket assembly building, the satellite, cryogenic engine and the second stage have been destacked. It has been decided to shift the second stage to Mahendragiri for detailed inspection and study,” the ISRO official told IANS. He said ISRO has also decided to start assembling another engine so that the GSLV could fly at the earliest. Queried about the time-frame for the GSLV’s flight, he said: “It is not possible to give a time-frame for the GSLV’s flight now.”
The first launch of Japan’s new Epsilon rocket was scrubbed today at T-19 seconds.
The press releases are very unclear, which is typical for the Japanese. From my perspective, this scrub is hardly a disaster for a new rocket, and is in fact a good sign. Better for the rocket systems to recognize a problem and abort than for it to launch anyway and fail.
