Blurred vision a risk for astronauts who spend months in space

Blurred vision is now considered a serious risk for astronauts who spend months in space.

According to one NASA survey of about 300 astronauts, nearly 30 percent of those who have flown on space shuttle missions – which usually lasted two weeks — and 60 percent who’ve completed six-month shifts aboard the station reported a gradual blurring of eyesight.

This story is a followup on information contained in an earlier National Academies report on astronaut staffing.

Another look at the cost of building NASA’s heavy lift rocket

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:

Private Japanese weather company to launch satellite to track Arctic Ice

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.

NASA to unveil its heavy-lift rocket design

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.

NASA and ATK sign new launch development agreement

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).

Speculation on what the ATK/NASA announcement later today will be about

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.

House proposes trimming budget of FAA’s commercial space office

A House subcommittee has proposed trimming the budget of the FAA’s commercial space office from the $15.2 million it received in 2010 and 2011 to $13 million for 2012.

This is good, to my mind. Cutting their budget will pull the teeth from their regulatory efforts. As the commercial space industry ramps up, the political pressure on this office to approve permits will increase, and if they are short of cash they will have no choice but to keep things simple and say yes.

Update: Thanks to Joe2 for noting my error: the budget numbers above have been corrected to millions, not billions.

Senators lambast Administration for SLS budget numbers

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

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.

Virgin Galactic hosts an industry day at New Mexico spaceport

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.”

The dangerous environment of space

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.

Sticker shock over Congressionally designed rocket

The Obama administration has discovered that the cost to build the program-formerly-called-Constellation, required by Congress, is going to be far more than they can stomach.

White House budget officials increasingly are concerned that some of NASA’s manned-exploration plans may be unaffordable, especially as the space agency weighs options that would raise the cost by billions of dollars by speeding up the development of rockets and spacecraft, according to people familiar with the issue.

The cost concerns are coming to a head, these people said, as the White House Office of Management and Budget ratchets up questions about NASA’s proposed program in light of the current emphasis on deficit reduction.

None of this surprises me.

New images of Apollo landing sites on the Moon

The Lunar Reconnaissance Orbiter team have released new images of the Apollo 12, 14, and 17 landing sites on the Moon. Below is a cropped image of the Apollo 12 site, showing the trails left by astronauts Pete Conrad and Alan Bean when they walked from their lunar module to Surveyor 3, an unmanned lunar lander that had soft landed there two years earlier. The full image shows some incredible detail.

Some suggestions for keeping ISS occupied

Some suggestions for keeping ISS occupied.

I especially like Harman’s suggestion that the Russians consider landing in the U.S. during the winter, thereby allowing them to extend one crew’s occupancy of ISS into December, January, or even February. Also, he proposes the Russians send an unmanned Soyuz to ISS during testing of the rocket, thereby providing the crews onboard a fresh lifeboat. This is something they have done in the past on their previous space station Mir.
