The engine of Japan’s troubled Venus probe, Akatsuki, has been found too damaged to put the probe into Venus orbit.
JAXA conducted a test ignition of the probe’s main engine on Wednesday to prepare for another attempt to send it into orbit in 2015. But the thrust produced was only one-eighth the amount anticipated, the space agency said. The damage the engine suffered last December when JAXA ignited it in the initial attempt to send the probe into orbit around Venus appears to be more serious than thought, JAXA said.
One of the two three-man crews on ISS have returned safely to Earth, despite an unexpected communciations blackout during their descent.
In related news, the Russians have slightly delayed the launch dates for the next manned flights to ISS, which also means that the next test flight of Falcon 9/Dragon will have to be delayed until 2012. Moreover, the Russians are once again balking at allowing Dragon to dock with ISS on this first flight.
An evening pause: Walking on water. As the youtube website explained, “They filled a pool with a mix of cornstarch and water made on a concrete mixer truck. It becomes a non-newtonian fluid. When stress is applied to the liquid it exhibits properties of a solid.”
Clark Lindsey takes another look at the cost for building the Congressionally-mandated heavy lift rocket, what NASA calls the Space Launch System and I call the program-formerly-called-Constellation. Key quote:
Finally, I’ll point out that there was certainly nothing on Wednesday that refuted the findings in the Booz Allen study that NASA’s estimates beyond the 3-5 year time frame are fraught with great uncertainty. Hutchison and Nelson claimed last week that since the near term estimates were reliable, there’s no reason to delay getting the program underway. That’s the sort of good governance that explains why programs often explode “unexpectedly” in cost after 3-5 years…
In other words, this is what government insiders call a “buy-in.” Offer low-ball budget numbers to get the project off the ground, then when the project is partly finished and the much higher real costs become evident, Congress will be forced to pay for it. Not only has this been routine practice in Washington for decades, I can instantly cite two projects that prove it:

The story behind the Italian prosecution of six scientists and one government official over their failure to make an earthquake prediction.
As is usual in these kinds of stories, things are more complicated than they appear at first glance.
Virgin Galactic expects to make its first launch of SpaceShipTwo within a year.
“The mother ship is finished… The rocket tests are going extremely well, and so I think that we’re now on track for a launch within 12 months of today,” [Richard Branson] told CNN’s Piers Morgan late Wednesday.
A private Japanese weather company plans to launch a satellite to track Arctic ice for use by shipping.
The satellite will transmit images and information about sea ice in the Arctic Ocean. Weathernews will combine the information with available data on sea currents, weather and wave height to provide consumers with a finished product enabling safe navigation along the northern route.
Though I know most people are skeptical of this idea, I think that all weather information should be gathered and sold by private companies, as Weathernews is doing above. For example, the Weather Channel makes its money providing weather information to the public. If they didn’t get the satellite data free from NOAA weather satellites, they would have every reason to launch their own satellites.
Two stories, one from AP and the other from Florida Today, say that NASA will announce today the design of its heavy-lift rocket, mandated by Congress and estimated to cost around $35 billion. Here is NASA’s press release. To me, this is the key quote (from AP):
NASA figures it will be building and launching about one rocket a year for about 15 years or more in the 2020s and 2030s, according to senior administration officials who spoke on the condition of anonymity because the announcement was not yet made. The idea is to launch its first unmanned test flight in 2017 with the first crew flying in 2021 and astronauts heading to a nearby asteroid in 2025, the officials said. From there, NASA hopes to send the rocket and astronauts to Mars — at first just to circle, but then later landing on the Red Planet — in the 2030s. [emphasis mine]
In other words, after spending $1.7 on the National Space Plane, $1.2 billion on the X-33, $1 billion on the X-34, $800 million on the Space Launch Initiative, and finally, almost $10 billion on Constellation, none of which ever flew, NASA is now going to spend another $35 billion on a new rocket that won’t fly for at least another decade.
To be really blunt, this new rocket, like all its predecessors, will never fly either. It costs too much, will take too long to build, and will certainly be canceled by a future administration before it is finished. It is therefore a complete waste of money, and any Congress that approves it will demonstrate how utterly insincere they are about controlling spending.
A clarification: Some of the $35 billion mentioned above has already been spent for the Orion capsule. This however still does not change any of my conclusions.
Astronomers plan one last close look at 1,900-foot-wide asteroid before sending a space probe there to collect samples.
Discovered in 1999, the OSIRIS-REx target asteroid, designated 1999 RQ36, nears Earth once every six years. During the 2011 closest approach in early September, it will be 10.9 million miles (17.5 million kilometers) away. In 1999, closest approach was 1.4 million miles (2.3 million kilometers).
Strangely, the article above never mentions the fact that 1999 RQ36 has 1 in a 1000 chance of hitting the Earth in 2182, which to my mind is the primary reason for studying it.
One man’s 9/11 idea to rescue people from high-rise buildings.
It involves attaching a harness around your body. Attached to the harness is a Kevlar rope that is secured at one end to a radiator or pipe. You then pop out of a window and rappel down the face of the building using a device which controls the rate of descent at 6 feet per second. Think of it as a fishing reel with a human attached.
At a press conference today, NASA and ATK announced a new launch development agreement, running through March 2012, to help develop ATK’s Liberty solid rocket into a launch vehicle that could bring both cargo and crews to ISS.
The agreement provides ATK no funds, but is designed to give ATK as much support from NASA as possible in developing Liberty, tested fired last week for only the third time. If this initial agreement goes well, it will position ATK to compete for the next round of development subsidizes.
According to ATK, they think they could launch by 2015, and are hoping to provide a rocket capable of flying the spacecraft and freighters of Boeing, Sierra Nevada, Blue Origin, and even SpaceX (should Falcon 9 have problems and they need a rocket to launch Dragon).

More speculation here and here on what the ATK/NASA announcement later today will be about. As Jeff Foust notes,
Last Friday NASA announced that the space agency and ATK would announce an agreement this Tuesday “that could accelerate the availability of U.S. commercial crew transportation capabilities”. (The announcement was originally going to be only available to media calling into a telecon line, but NASA said Monday the announcement will be on NASA TV at 3 pm EDT.) The announcement has generated various degrees of glee or despair, depending on one’s opinions about ATK’s work on solid rocket motors it has proposed for its Liberty rocket and is seeking to have incorporated into NASA’s Space Launch System (SLS) heavy-lift rocket.
This is not good if true: SpaceX has admitted that in its December 2010 test flight of Falcon 9 there was a problem with its first stage.
During the August meeting, held at the Johnson Space Center in Houston, SpaceX told to the two advisory bodies that there had been an engine anomaly during the most recent Falcon 9 launch, according Charles Daniel, a shuttle and space station safety expert at Herndon, Va.-based Valador Inc., and a member of the ISS Advisory Committee. “There was no explanation or root cause analysis or corrective action for this particular anomaly,” Daniel said Sept. 9 during the public meeting. “This is a relatively troublesome statement not to recognize that a premature engine shutdown was a significant event.”
ATK and NASA to announce a new commercial space agreement on Tuesday.
This is almost certainly in connection to the successful third test firing of ATK’s solid rocket yesterday.
The space war heats up: Two senators have issued a statement lambasting the Obama Administration for its budget numbers for building the program-formerly-called-Constellation.
All of this is fantasy and foolishness. These senators might succeed in forcing NASA to spend money on the heavy-lift rocket that Congress has mandated, but there is no way the space agency will ever get enough funding or time to finish it. Even if the lower estimates are right, the cost is exorbitant, many times that of what the private companies have spent for their rockets and ships. And if construction does begin in earnest, it cannot be finished before the arrival of a new President in 2016 (at the latest), who, like all new Presidents, will have his own plans and will not want to build something started by the previous administration.
Much better to end this farce and save the money, especially considering the debt of federal government.
More Progress freighter crash investigation results: it appears there was something that blocked the fuel supply.
“The exposed production defect was accidental,” [the investigation] said, adding the reason may be qualified as an isolated case only after checking all available engines.
This suggests that the problem was an isolated error and that, once they have cleared the available engines, they can start flying relatively quickly.
ATK today successfully test fired the five segment solid rocket originally intended for the Ares 1 rocket. More here.
This solid rocket motor has value, but ATK’s hope that NASA will use it as part of the Congressionally designed Space Launch System, what I call the program-formerly-called-Constellation, is probably a false hope. They might get a few years of funding from Congress, but the whole thing will die stillborn when the funding runs out.
Better that they packaged the motor as part of a private launch system and tried to get some commercial business with it.
Regardless, the video is fun to watch. Check it out.

The Upper Atmosphere Research Satellite, or UARS, is expected to come down in late September or early October, the space agency said today in an advisory. “Although the spacecraft will break into pieces during re-entry, not all of it will burn up in the atmosphere,” NASA said.
Virgin Galactic announced today that it will co-host an industry day at Spaceport America in New Mexico on October 18 in order to locate suppliers for its space tourism business.
“This is a fantastic opportunity for companies ranging from local New Mexico firms to national corporations to understand our unique needs for goods and services, including our requirements in building and servicing multiple commercial spaceships as the market further develops,” said Virgin Galactic’s President and CEO George Whitesides. “Our intention is to establish these relationships and emphasize our desire to hire locally as much as possible.”
A just released report from the National Academies, Preparing for the High Frontier: the role and training of NASA astronauts in the post-space shuttle era, describes the challenges that NASA faces in staffing its astronaut corps in the coming years. More important, however, is some new information buried in the report about the hazards of long term exposure to weightlessness.
For example, it seems a significant number of astronauts have come back from spending months at ISS with serious vision problems, caused by a newly discovered condition dubbed papilledema, the swelling of the optic disk.
