Q: (CNN) -- Lewis Hamilton endured a nightmare start to testing his new Mercedes after driving straight off the track at Jerez on his first day following a hydraulic problem Wednesday.

The 2008 world champion, who left McLaren at the end of last season, was on his 15th lap of timed testing when his car went off the track and hit a barrier of tires.

Hamilton's accident, which prevented him from returning to action, follows teammate Nico Rosberg's disastrous run which was ended by a minor fire Tuesday.

The German's car was found to have been suffering with electrical problems, while Mercedes took to Twitter to give an update on Hamilton's setback.

"Lewis suffered a loss of rear brake pressure, the front brakes enabled him to slow the car but he couldn't avoid the barrier," said Mercedes on Twitter.

"Obvious damage to the front wing and nose; we're checking the car over now. Lewis himself is fine.

"Update from Jerez, we have traced the problem to the hydraulic brake line connecting to the right-rear caliper."

Hamilton is expected to return to the track on Friday following the collision, which saw the car career on straight for some 70 meters at 280 kilometers per hour.

Meanwhile, Russian team Marussia has replaced Timo Glock with Brazil's Luis Razia as its second driver for the 2013 season.

The 23-year-old, who finished as runner-up in last season's GP2 series, will partner fellow rookie Max Chilton when the campaign starts in Australia on March 17.

Q: For more than 40 years, scientists have sought to learn how well human beings can adapt to long periods in space. The International Space Station continues to provide valuable knowledge about spaceflight. But an earlier space station, Skylab, helped make the current space project possible.

Canadian astronaut Chris Hadfield sang aboard the International Space Station on May 12, 2013. His music video has become extremely popular. The astronaut played his own version of David Bowie's song Space Oddity. He performed while floating weightlessly, with images of planet earth and space appearing in the window behind him.

Chris Hadfield recently returned home after nearly five months on the space station. For him, the long flight produced a hit video on YouTube and no major physical problems. But 40 years ago, scientists did not know how humans would react to long-term spaceflight. To find out, NASA, the American space agency, launched Skylab in May, 1973. Over nearly a year, three teams of astronauts visited Skylab for stays of between 28 to 84 days. They learned how people react to extended periods in space.

Gerald Carr commanded Skylab 4. He spoke at a NASA event marking the 40th anniversary of Skylab's launch. He said that the loss of the body's muscle mass was a main concern. Astronauts on Skylab used exercise equipment to stay strong. The astronauts spent their workdays carrying out experiments, including biomedical research.

Marshall Porterfield is the director of NASA's Space Life and Physical Sciences Division. He says the Skylab astronauts' understanding of their own ability to deal with long-term spaceflight continues to help current astronauts. NASA says the next step for life away from Earth is a year-long space station mission, set for 2015.

Q: (CNN) -- Last Saturday, Sarah Palin stood before the huge crowd at the 2014 National Rifle Association annual meeting and condemned liberals for coddling terrorists. She loaded her speech with religious metaphors, claiming that true leaders would put "the fear of God in our enemies." She said, "They obviously have information on plots to carry out jihad. Oh, but you can't offend them, can't make them feel uncomfortable, not even a smidgen. Well, if I were in charge, they would know that waterboarding is how we baptize terrorists."

Palin's invocation of forced baptism shocked both conservatives and liberals, inspiring few defenders. Christian commentators, in particular, focused on her link between torture and baptism.

On Wednesday, the National Religious Campaign against Torture released a powerful condemnation of the speech. To Palin, the organization's executive director wrote, "Your statements play into a false narrative conveying that somehow, the conflict between the United States and the terrorist cells is a conflict between Christianity and Islam, or Islam and 'the West.' "

The group's letter to the NRA, signed by 17 faith leaders from many different religions and denominations, reads, "For Christians, baptism is a profoundly holy act. It is in stark contrast to the abhorrent act of waterboarding. Equating baptism to an act of torture like waterboarding is sacrilegious -- and particularly surprising coming from a person who prides herself on her Christian faith."

But it's not actually all that surprising. Palin's public rhetoric relies on crafting existential binaries between "us" and "them," creating a kind of sacred empowered victimhood among her listeners. She draws from the language of militant Christianity to claim the status of both persecutor and persecuted. This is not an accident, and I do not believe she will repudiate her remarks.
