Threatened water shortage on ISS

9:42 am

The crash of Antares and its Cygnus capsule in October has caused the possibility of a water shortage on ISS.

NASA had planned to certify Cygnus to carry water to the space station in early 2015; there were no plans for certifying SpaceX’s Dragon cargo ship to do the same. Orbital plans to launch its next Cygnus aboard a United Launch Alliance Atlas V rocket, but that flight is not scheduled until Nov. 19.

Meanwhile, ESA has ended flights of its ATV cargo ship, which was certified to carry water. With the ATV program over and Cygnus off-line, the space station was left with two vehicles capable of carrying water, the Russian Progress and Japanese HTV.

HTV flights are now limited to once per year; the next one is planned for August 17, just over two weeks before ISS would run out of water on Sept. 2 unless it was resupplied by other vehicles. The schedule provided very little margin for error, ASAP said.

Essentially, if either a Progress or Dragon capsule does not bring additional water to the station before August, and the HTV flight fails or is delayed by more than two weeks, the station will run out of water in early September, requiring its evacuation.

Hayabusa-2 in “tip-top” shape

9:34 am

Launched in December for a 2018 rendezvous with an asteroid, Hayabusa-2 has successfully completed its initial check-out according to Japanese officials.

Checkups on early-phase functionality are being carried out over a three-month period. Although the first Hayabusa had suffered malfunctions of its ion engines, it is confirmed that the four ion engines of Hayabusa-2 are functioning properly, JAXA said. Kuninaka said: “With the engines functioning, the explorer can set out on its voyage with a lot of leeway. I feel like, ‘Way to go!’”

Privately-built weather satellite constellation to be built

9:25 am

The competition heats up: A private company, dubbed Spire, has announced its intention to launch a 20-satellite constellation of weather satellites, all cubesats, by the end of 2015.

Spire raised $25 million in Series A funding during the summer of 2014, bringing its total amount to $29 million. The company already has customers in a variety of verticals, but Platzer said weather was planned to be a focus from the company’s inception.

…With the U.S. National Oceanographic and Atmospheric Administration (NOAA) facing an impending weather data gap, an increasing amount of focus has been placed on leveraging commercial options as well. Last year NOAA issued a Request for Information (RFI) on RO that piqued interest from the commercial sector. Congress has also urged the agency to leverage private sector capabilities.

For years I argued that there is no justification for the federal government to provide free weather satellite data to private companies like the Weather Channel. There is more than enough profit to be made tracking and predicting the weather for these companies to launch their own orbiting networks, just as the television and communications industries do. Thus, it is good to see a new start-up take advantage of this need and to push to make a business out of it.

Boeing’s commercial manned space effort

9:15 am

In reading this review of Boeing’s commercial manned space effort, this particular quote from Boeing Vice President John Elbon stood out:

“This year Boeing is celebrating its 100th year as a company. Bill (William) Boeing founded the company with a focus on flying air mail and establishing commercial air transportation through United Airlines. If you look at the company today, the commercial airline division of the company is a 70 billion dollar per year business.

“I believe firmly that when the company celebrates its second hundred years, there will be a division of Boeing building commercial space vehicles that will be of that magnitude.” [emphasis mine]

I see no reason not to agree with Mr. Elbon. If Boeing and SpaceX both get their manned vehicles working, and SpaceX and ULA begin to really compete for the launch market, the possibilities are as endless as they were 100 years ago during the early days of the aviation industry.

Update on Philae on Comet 67P/C-G

9:01 am

The Rosetta team has provided a detailed update describing their so far unsuccessful search for Philae on the surface of Comet 67P/C-G.

In addition, the update also looks into the possibility that Philae might wake up in the late spring when the comet’s orbit and rotation changes enough so its solar panels are more exposed to the Sun.

Bottom line: Don’t expect them to find the lander from images. Right now it is a mere three pixels in size. And whether it will come back to life as well also remains unknown.

Color snapshots of England 1960

7:28 pm

A collection of snapshots purchased on ebay gives us a peek into life in England around 1960.

Because they are in color they show us that the past was not drab and colorless, but as bright as life today. There are differences, however, and they hint at how our western culture has evolved in the past half century, not necessarily for the better.

Manned balloon approaches North America

10:19 am

In its effort to set a new record for the longest gas-filled balloon flight, the two-man Two Eagles flight has now almost crossed the Pacific and expects to reach the west coast of North America by Thursday evening.

The balloon’s speed, as expected, has slowed considerably as the balloon enters calmer winds associated with a high pressure system along the West Coast. At this writing the balloon is west of northern California, and the team meteorologist, Luc Truellmans, predicts the ridge will continue to pull the balloon north and then east into Canada.

Once they do reach North America they need only travel 100 miles more to set a new record.

Update: Because of weather shifting to the south.

Air Force gives more launches to ULA

9:30 am

The heat of competition? The Air Force has added three launches to its $4 billion bulk-buy contract with ULA, including one that SpaceX had hoped to bid on.

The timing of this contract award, worth $383 million, is most intriguing, coming as it does mere days after SpaceX had dropped its lawsuit with the Air Force. It is almost as if the Air Force was waiting for that lawsuit to go away before it gave more contracts to ULA. Note also the launch cost for these three launches: $383 million for 3 launches, or about $127 million per launch. That’s more than twice what SpaceX charges for a Falcon 9 launch.

It sure looks to me like the Air Force does not have the taxpayers’ interests at heart, and instead is working an inside deal to help its buddies at ULA.

Ted Cruz introduces bill outlawing political targeting of citizens.

11:00 am

Link here.

As Jazz Shaw notes at the link, “You mean that wasn’t already illegal?” Though Shaw does carefully analyze the political ramifications of making Democrats vote for or against these bills, ramifications that will likely weaken the power-hungry in government, my first thought when I read this was instead, “This is more evidence why I am increasingly not a big fan of Ted Cruz.”

You see, how does one really increase freedom and weaken the power of government by passing another law? You really don’t. This law might be politically effective, but if it should happen to pass and Obama actually sign it, all it will accomplish is create another law that can be used as a wedge to pry more power into government.

Cruz does this kind of showboating a lot. Though I almost always agree with him, the behavior illustrates why a senator is not the best choice for President. We don’t need a showboat right now. We need a conservative President who understands how to run a hostile executive branch even as he cuts its power and influence and still wins elections.

Sounds like Wisconsin Governor Scott Walker or Louisiana Governor Bobby Jindal, doesn’t it? Both have the right qualifications, winning elections even as they were being slimed by the left wing union, media, and Democratic Party attack machine for actually cutting the power of these power-hungry groups.

As a senator Ted Cruz does not have and cannot get that track record. Worse, he has made me doubt his tea party sincerity with his talk of rebuilding NASA and going to Mars. Instead of trimming the waste in NASA, it appears he wants to keep feeding the Texas pork that NASA sends his way.

The surprisingly dark and organic surface of Comet 67P/C-G

9:02 am

Link here.

The first surprising result emerging from VIRTIS’s study of Comet 67P/Churyumov-Gerasimenko is the measurement of its albedo, or how much sunlight is reflected by the surface of the nucleus. With an albedo of only 6%, about half as much as the Moon’s, 67P/C-G is one of the darkest objects in the Solar System. Such a low reflecting power indicates that the surface of the comet contains minerals such as, for example, iron sulfides, but also carbon-based compounds. The low albedo also indicates that there is little or no water ice on the outermost layers of the surface of the nucleus.

“This clearly doesn’t mean that the comet is not rich in water, but only that there is no water ice in the outermost shell, just over one millimetre thick,” explains Fabrizio Capaccioni, VIRTIS Principal Investigator from INAF-IAPS in Rome, Italy. “The reason for this is rooted in the recent history of the comet’s evolution, since repeated passes in the vicinity of the Sun cause surface ice to sublimate.”

This result, combined with other Rosetta data, also suggests that during each pass the dust that did not escape along the comet’s tail settled back down to coat the surface and hide the lower layers of water ice.

SpaceX animation of Falcon Heavy launch

8:56 am

The competition heats up: SpaceX has released a short animation showing the launch of its Falcon Heavy rocket, with all three of its Falcon 9 first stage boosters returning to the launchpad and landing vertically.

I have posted this animation below the fold. When NASA makes these kinds of animations, which the agency has been doing for more than forty years now, I pay little heed. They don’t signal any achievement, merely the dreams of the engineers there. In the case of SpaceX, however, I pay close attention, because the company’s track record is that they are likely to make this animation quite real in a surprisingly short period of time.

Enjoy!

JPL releases movie of asteroid fly-by

12:38 pm

Using 20 radar images of asteroid 2004 BL86 as it flew past Earth on January 26, scientists at JPL have created a movie showing the orbital motion of the asteroid’s moon.

The images also show one of the most spherical asteroids I have ever seen. Like Ceres, the larger size has helped shape the asteroid into a more typical-looking planetary sphere.

Massive federal/state program uncovered to track millions of cars nationwide

9:33 am

What could possibly go wrong? A massive federal/state government partnership has been built to track the movements of millions of cars as they move across the country.

The program is also linked to a number of databases that provide a significant amount of private information about the drivers of those cars. The program has also been designed to aid state and federal officials in their efforts to grab cash and property from citizens in their civil forfeiture programs.

Doesn’t that make you feel safe?

Solar system of ancient Earths found

8:49 am

Worlds without end: Using archived Kepler data astronomers have identified a solar system of five Earth-sized exoplanets, orbiting a red dwarf star about 117 light years from Earth.

The paper describes Kepler-444, a star that’s 25 percent smaller than our sun and is 117 light years from Earth. The star’s five known planets have sizes that fall between Mercury and Venus. Those planets are so close to their star that they complete their orbits in fewer than 10 days. At that distance, they’re all much hotter than Mercury and aren’t habitable.

The important detail from this discovery is that the star is very ancient, more than 11 billion years old, which means these planets are that old as well. In other words, planets began forming the same time as the first stars. Which also means that there has been plenty of time in the universe for other intelligent life to form, besides our own.

Asteroid that flew past Earth has its own moon

11:19 pm

Radar images of the large asteroid 2004 BL86 as it flew past the Earth today have revealed that it has its own small moon.

The new images also show a second object positioned close to 2004 BL86. Benner told Space.com that the second object is a moon, with a diameter between 164 and 328 feet (50 and 100 m). Previous studies of the light around 2004 BL86 had already identified a moon orbiting the asteroid, and the new images confirm that discovery, he added. About 17 percent of asteroids in 2004 BL86’s size range have smaller objects trailing along with them.

Boulders and other small-scale features on the surface of the asteroid are coming into focus in the new images, as is the overall shape of the asteroid, according to Benner. He compared the object to another asteroid that made a close flyby of Earth six years ago, called 2008 EV5. It appears that 2004 BL86, like 2008 EV5, has an equatorial ridge around its middle, which makes it look “kind of like a muffin, or perhaps a top,” said Benner, who’s based at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California.

This data is from radar data collected early in the fly-by, so we should expect even more details to come out in the next day or so.
