An Ammonia Leak Inside The Space Station

Six astronauts on the American side of the International Space Station had to evacuate to the Russian side of the orbiting science lab, Mashable reported. It's unclear what triggered the smoke and fire alarms, but earlier reports indicated a possible ammonia leak, which NASA has yet to confirm.

Ammonia is pumped throughout the space station to regulate temperatures and keep scientific investigations cool. In 2013, NASA approved two emergency spacewalks to fix a faulty ammonia pump module. The crew recently received the Dragon spacecraft, carrying 2.5 tons of cargo and scientific investigations. Dragon was attached to the Harmony node Monday and the crew unloaded the spacecraft Tuesday.

"Acting conservatively to protect for the worst-case scenario, the crew was directed to isolate themselves in the Russian segment while the teams are evaluating the situation. Nonessential equipment in the U.S. segment of the station was also powered down per the procedures," NASA said in a statement.

Jury selection began Tuesday for the trial of Ross Ulbricht, the alleged mastermind behind Silk Road, a massive drug marketplace that he is charged with running on the Tor Network under the pseudonym "Dread Pirate Roberts" before the FBI shut it down in 2013. Ulbricht's lawyer, Joshua Dratel, admitted that his client started Silk Road but said that he gave up control of the marketplace within a few months. Dratel described Ulbricht as the "perfect fall guy."

Ulbricht's case was called the "most important trial in America" by The Daily Beast. "If you care about due process, Fourth Amendment protections against illegal searches, the limits of government surveillance and Internet freedom, you should pay attention," author Nick Gillespie wrote.
