Here’s what it used to be like, when we lived in a free society:
By the 1920s and 30s children had access to substances which would raise eyebrows in today’s more safety-conscious times. There were toxic ingredients in pesticides, as well as chemicals now used in bombs or considered likely to increase the risk of cancer. And most parents will not need to be told of the dangers of the sodium cyanide found in the interwar kits or the uranium dust present in the “nuclear” kits of the 1950s.

One of Kepler’s reaction wheels — used to orient the space telescope — has failed.
Bad news: One of Kepler’s four reaction wheels — used to orient the space telescope — has failed.
Kepler only needs three wheels to function – one to control the probe’s motion along each axis – and the probe resumed its observations on 20 July. “Kepler is functioning very well on three reaction wheels,” says mission manager Roger Hunter of NASA’s Ames Research Center in Moffett Field, California. If the glitch can’t be fixed, though, Kepler will be left without a backup wheel. “This is reducing the odds of making the mission go as long as we can,” says Kepler chief scientist William Borucki of NASA Ames, who doubts that Kepler could point accurately enough to look for transiting planets if reduced to two reaction wheels. “It was a disappointing surprise to find this wheel stopped so early.”

Russia has announced it has begun construction on a lunar lander, set for its first unmanned test flight in 2015.
The competition heats up: Russia has announced it has begun construction on a manned lunar lander, set for its first unmanned test flight in 2015.
There have been many such announcements from Russia over the past decade with few ever coming true, since such announcements are generally nothing more than a public relations lobbying effort to get funding.
The most intriguing part of this article however was this quote:
Last week, head of the Lavochkin Scientific and Production Corp. Victor Khartov said Russia must “return to the Moon in 2015 in a Soviet style, to prove everyone and ourselves that we remember all the Soviet Union could do” at the Farnborough air show in Britain.
I would interpret this statement as a desire for Russia to compete more aggressively with the U.S. and others, as they did back in the days of the Soviet Union. It was also in that time period that the Lavochkin center was in its heyday, with lots of money and research work.

Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.
Russia is considering shortening the time it takes for its Progress and Soyuz capsules to reach ISS after launch, from 50 hours to 6.
The long travel time was designed to save fuel at launch — thus increasing payload — by allowing orbital mechanics to bring the capsule and station together. I wonder then why the Russians are considering this change. Have the figured out a way to save the fuel in other ways?

Another opinion: NASA’s Space Launch System (SLS) is costing 320 times more than NASA’s commercial space program.
In other words, having NASA build a rocket and capsule makes no financial sense. At these numbers, SLS cannot survive.

Astronomers have discovered the first exoplanet smaller than Earth.
Astronomers have discovered the first exoplanet smaller than Earth.
The University of Central Florida has detected what could be its first planet, only two-thirds the size of Earth and located right around the corner, cosmically speaking, at a mere 33-light years away. The exoplanet candidate called UCF 1.01, is close to its star, so close it goes around the star in 1.4 days. The planet’s surface likely reaches temperatures of more than 1,000 degrees Fahrenheit. The discoverers believe that it has no atmosphere, is only two-thirds the gravity of Earth and that its surface may be volcanic or molten.
What is especially remarkable about this discovery is that the scientists used the Spitzer Space Telescope to do it, detecting the planet’s transits across the star’s face, just like Kepler. Spitzer was not designed to be able to do this.
