The competition heats up: India today successfully launched six commercial satellites into orbit using its smaller PSLV rocket.
During the flight they also tested the ability of the rocket’s fourth stage to restart its engines in orbit, a necessary ability for later commercial launches.
The competition heats up: China has begun development of two versions of a second generation manned capsule.
Instead of the three-module arrangement of the current Shenzhou vehicle, the future Chinese crew vehicle will adopt a two-module arrangement, with a large inhabitable crew module at the front, and an uninhabitable cylindrical-shaped service module at back. The size of the re-entry vehicle will be twice of Shenzhou’s, capable of accommodating up to six crew members. A docking port and its associated docking sensors are fitted to the front-end of the crew module. The spacecraft can be fitted with two different service modules, with different propulsion systems and propellant capacities.
In other words, rather than copy and upgrade the design of the Russian Soyuz, as they did with their Shenzhou capsule, they will copy and upgrade the American Apollo capsule.
An evening pause: As we move into the heart of the Christmas season, this piece from the 1974 Bob Hope Christmas Special will allow us to remember a time when the idea was to express some good cheer and good will, not whine about oppression because someone said something we didn’t like or agree with. Note that a few of Hope’s jokes at the beginning are very time sensitive, as this was aired just after the 1974 elections where the Republicans got badly beaten. Hope, who was Republican, still had no problem cracking jokes at his own party’s expense.
Hat tip Danae.
I will be doing one of my regular two hour appearances on David Livingston’s The Space Show tonight, starting at 7 pm (Pacific). We will likely spend some time talking about the election campaign in conjunction with space, along with a bunch of other topics. Should be fun.
A new government audit has found that the EPA broke the law with its aggressive social media campaign lobbying in support of the Obama administration’s proposed clean water regulations.
The Environmental Protection Agency engaged in “covert propaganda” and violated federal law when it blitzed social media to urge the public to back an Obama administration rule intended to better protect the nation’s streams and surface waters, congressional auditors have concluded.
The ruling by the Government Accountability Office, which opened its investigation after a report on the agency’s practices in The New York Times, drew a bright line for federal agencies experimenting with social media about the perils of going too far to push a cause. Federal laws prohibit agencies from engaging in lobbying and propaganda. “I can guarantee you that general counsels across the federal government are reading this report,” said Michael Eric Hertz, a professor at the Benjamin N. Cardozo School of Law in New York who has written on social media and the government.
I am sure this news comes as a complete surprise to everyone. Who ever heard of a modern government agency ignoring the law for its own benefit? The concept boggles the mind!
In the past forty years the use by scientists of descriptive words to positively hype their results in their papers has increased steadily.
Researchers at the University Medical Center Utrecht in the Netherlands say that the frequency of positive-sounding words such as ‘novel’, ‘amazing’, ‘innovative’ and ‘unprecedented’ has increased almost nine-fold in the titles and abstracts of papers published between 1974 and 2014. There has also been a smaller — yet still statistically significant — rise in the frequency of negative words, such as ‘disappointing’ and ‘pessimistic’.
…The most obvious interpretation of the results is that they reflect an increase in hype and exaggeration, rather than a real improvement in the incidence or quality of discoveries, says Vinkers. The findings “fit our own observations that in order to get published, you need to emphasize what is special and unique about your study,” he says. Researchers may be tempted to make their findings stand out from thousands of others — a tendency that might also explain the more modest rise in usage of negative words.
The word ‘novel’ now appears in more than 7% of PubMed paper titles and abstracts, and the researchers jokingly extrapolate that, on the basis of its past rise, it is set to appear in every paper by the year 2123.
This study was focused on the medical field, so it is unclear if its results could be extrapolated to other science fields. I suspect it can.
This article provides a detailed account of the political battle between ULA and Congress of its future use of Russian engines in its Atlas 5 rocket.
Congress has imposed a strict limit on the number of engines the company can use. ULA is still lobbying for an increase, claiming that the limit will mean that they will not be able to meet the government military launch needs for a few years when the engines on hand run out and its new American-built engines are not yet available.
In the long run I think this battle is irrelevant. What really matters is what it costs to launch a satellite, and ULA is simply not focused on reducing its costs. Consider this quote from the article, emphasis mine:
ULA has designed a new rocket dubbed Vulcan that features a U.S.-made engine, but this vehicle will not be available until around 2021, assuming the project gets funded — which is by no means a given.
They made a big deal earlier this year about how Vulcan will soon replace Atlas 5 at a lower cost, but it now appears that this was merely a public relations event. ULA wants someone else to pay for this new rocket, and thus has not yet committed any of its own money to begin actual development.
Other companies however are funding the development of their own new American-made rockets that will also be far cheaper to fly. Sooner rather than later our spendthrift Congress is going to mandate that the military use those cheaper rockets. If ULA doesn’t get moving it will be left in the dust, whether or not Congress allows it to use more Russian engines.
A Russian Soyuz rocket today successfully launched a new crew to ISS, including Great Britain’s first official astronaut.
Tim Peake is not the first Brit in space, but he is the first paid for by the British government. The first British citizen to fly in space, back in 1991, was Helen Sharman, whose flight was a publicity stunt mostly paid for by the Russians themselves.
The crew is expected to dock with ISS later today.
Lots of cool images! The science team running Rosetta’s high resolution camera have finally made available to the public the camera’s large archive of images.
The images cover the period 20 June 2014 – 16 September 2014, corresponding to Rosetta’s approach to the comet, arrival, and insertion into orbit.
In exchange for creating and running the mission, the scientists had been given a 12 month period in which these hi-res images belonged entirely to them. This gave them the chance to use them to publish papers documenting their discoveries. While this is a reasonable arrangement — used by most planetary missions in some manner to reward the scientists who made the mission possible — with Rosetta the hi-res images were kept so close to the vest that practically none have been seen, until now. Moreover, this release is very late, anywhere from 15 to 18 months after the images were taken, not 12.
Most other planetary missions make sure that at least some images are released as the mission proceeds, since the images were paid for by the public. The European Space Agency should take a look at its future policies for publicly-funded missions to make sure the public gets better access in the future.
An evening pause: Hat tip Tom Biggar.
The competition heats up: Russia’s Proton rocket successfully launched a military communications satellite on Sunday.
The link provides a lot of interesting information about the satellite as well as some recent upgrades the Russians have installed in Proton, but for context the last two paragraphs are probably the most important:
Sunday’s launch was the seventy ninth orbital launch attempt of 2015 and the seventh Proton launch of the year. Five of the six previous launches were successful, with May’s launch of Mexsat-1 failing to achieve orbit. Proton has had eleven failures in the last ten years, with 2009 the only year since 2005 in which it has not suffered at least one anomaly.
The next Proton launch is scheduled for 23 December, with another Proton-M/Briz-M carrying the Ekspress-AMU1 communications satellite. Details of any future Garpun launches are not available.
The launch reliability for Proton has seriously fallen since 2005, and to compete in the changing launch market they will need to fix this.
Engineers have determined that Hayabusa-2’s fly-by of Earth on December 3 successfully put the spacecraft on the right course to rendezvous with asteroid Ryugu in 2018.
