NASA Mars satellite shifts course to avoid hitting planet’s moon

Published

A NASA science satellite orbiting Mars was forced to make a rare evasive maneuver to avoid a collision next week with one of the planet’s two small moons, the U.S. space agency said on Thursday.

Flight controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California, commanded the MAVEN spacecraft, which is studying Mars’ vanishing atmosphere, to fire up its engine on Tuesday to boost its speed by about 1.3 feet per second (0.4 meters per second).

The acceleration was necessary to slightly shift MAVEN’s orbit and steer the satellite clear of the Martian moon Phobos, the National Aeronautics and Space Administration said in a statement.

Without the tweak, MAVEN and the small, lumpy moon would have reached the same point in space within seven seconds of one another next Monday, March 6. In its new orbit, MAVEN will miss Phobos by about 2-1/2 minutes, NASA said.

MAVEN is in an egg-shaped orbit that regularly crosses the paths of other science satellites and of Phobos, which circles just 6,000 miles (9,656 km) above the Martian surface, closer than any other known moon to a planet in the solar system. At that distance, Phobos whips around Mars three times a day.

Flight controllers regularly monitor MAVEN’s path for potential collisions. Tuesday’s evasive action was the first time MAVEN had to dodge the potato-shaped Phobos, which measures about 10 by 14 miles by 11 miles (16 by 22.5 by 18 km).

Brian Williams compares Corey Lewandowski’s opening statement to the North Korean news lady

MSNBC host Brian Williams on Tuesday noted the similarities between former Trump campaign manager Corey Lewandowski and North Korean news anchor Ri Chun Hee.

"Corey Lewandowski, the former Trump campaign manager who is now considering a Senate run in New Hampshire, testified before the House Judiciary Committee today," Williams reported. "It is likely his North Korean anchorwoman-quality opening remarks were meant were one viewer (Donald Trump)."

Ri, who has earned the nickname "Pink Lady," is known for her enthusiastic reading of government-approved news.

‘Train-wreck of a witness’: Analysts nail ‘obstructive’ Corey Lewandowski for proving the Democrats’ case

Published

on

Political commentator Catherine Rampell disagreed with New York Times columnist Frank Bruni that the Democrats faltered during the hearing with Corey Lewandowski Tuesday. Former state and federal prosecutor Elie Honig called Lewandowski a "train-wreck of a witness."

She explained that Democrats had an extremely low bar: they had to prove Trump obstructed justice and that Corey Lewandowski gave one of the examples of such obstructions. In that sense, Rampell said they accomplished their goals.

"I don’t think this was a great day for Corey Lewandowski," she began. "This is a guy who went on TV and announced to the world -- apparently at the same time he is also trying to fundraise for Senate -- that he lies most of the time. Except when he's under oath."

WATCH: Ana Navarro keeps shouting down Trump booster — even as CNN host cuts to commercial

Published

President Donald Trump cheered on his top Hispanic advisor Steve Cortes, who appeared before a New Mexico audience. Trump asked Cortes which he loved more, Hispanics or America, which prompted CNN's Ana Navarro to blast the president for racism. Meanwhile, Trump's latest CNN shill cried "political correctness."

"Look, I suspect he didn't want to offend Steve Cortes and I suspect Steve Cortes was not offended," Navarro said. "But really what a stupid thing to say. Right? To somehow ask the question about whether you love the country more than you love Hispanics -- they are one and the same."
