Despite a rest, Kepler’s problematic gyroscope is still having problems.

Despite a rest, Kepler’s problematic gyroscope is still having problems.

Three of the wheels are needed for Kepler’s 3.1-foot telescope to have enough sensitivity to detect the minuscule signatures of Earth-sized planets. In an exercise of caution, mission managers switched off Kepler’s reaction wheels for 10 days in January, hoping the break would redistribute lubricant inside the wheel assemblies, reducing friction and allowing the units to cool down.

But friction in wheel no. 4, which has showed friction for much of Kepler’s mission, actually increased in the month following the “wheel rest” period.

The telescope originally had four wheels. One has failed, with a second showing signs of failure. If it goes, the spacecraft will no longer be able to point with enough accuracy to do its primary mission. They might be able to use it to some observations, but its design is such that even these will be of limited value.

The competition heats up: Vladimir Putin noted today, the anniversary of Yuri Gagarin’s spaceflight, that the new Russian spaceport being built in Vostochny will be open for use by other countries.

Putin’s announcement is a bit vague, in that it is not clear whether he means the spaceport could be used by outside private companies or merely that American or European payloads will be launched from the site using Russian rockets. I suspect the latter. Regardless, Putin’s statement both to the Russian public and to the rest of the world illustrates his desire to sell the new spaceport, which in turn will bring Russia business.

Isn’t competition a wonderful thing?

Since 2010 total government spending per household has exceeded what each household earns per year.

The day of reckoning looms: Since 2010 total government spending per household has exceeded what each household earns per year.

In other words, even if the federal, state, and city governments took 100 percent of your income in taxes, they still wouldn’t get enough money to pay their expenses. And since government spending has continued to rise since 2010 amid a stagnant economy, this situation has worsened, not improved. Worse, in 2012 the public voted in favor of accelerating this situation by voting for more Democrats in the Senate, while keeping a spendthrift Democratic President in power.

We are going bankrupt. It is only a matter of time.

The Fantasy of Extreme Weather

10:06 am

This week there were three stories describing new research proving that global warming is going to cause an increase in the number and violence of extreme weather events. Each was published in one of the world’s three most important scientific journals.

Sounds gloomy, doesn’t it? Not only will extreme heatwaves, cold waves, and droughts tear apart the very fabric of society, you will not be able to drink your soda in peace on your next airplane ride!

However, one little detail, buried in one of these stories as a single sentence, literally makes hogwash out of everything else said in these three articles.

Boeing this week revealed a new line of small satellites, the smallest weighing less than 9 pounds, for both military and commercial operations.

The competition heats up: Boeing this week revealed a new line of small satellites, the smallest weighing less than 9 pounds, for both military and commercial operations.

This decision tells me that my worries about Boeing’s competitiveness are unfounded. Moreover, the increasing shift to building smaller satellites will once again lower costs and therefore increase the number of customers who can afford the product. The result will be a larger aerospace industry.
