Nigeria police recover stolen Senate mace under flyover

Nigeria police recover stolen Senate mace under flyoverNigerian police said on Thursday they had recovered the ceremonial mace -- the parliamentary symbol of authority -- under a flyover after it was stolen from the Senate. The mace was snatched on Wednesday by "hoodlums" suspected to have been hired by an embattled senator who had been suspended from the upper house because of a dispute over the date of the presidential election next year. Seizing the mace has been a long-established tactic to express discontent with parliamentary proceedings in the Senate and the lower House of Representatives, as well as state legislatures.

Surprise IS attack kills 25 regime forces in east Syria: monitor

Surprise IS attack kills 25 regime forces in east Syria: monitorThe Islamic State group launched a surprise attack near a town in eastern Syria they had lost six months ago, killing at least 25 regime forces, a monitor said Thursday. At least 13 jihadists were also killed in the attack which IS carried out near Mayadeen on Wednesday afternoon, the Syrian Observatory for Human Rights monitor said. Mayadeen lies in the eastern province of Deir Ezzor on the western bank of the Euphrates River and is flanked by the vast Badia desert to its west and south.

Nasa launches Tess: planet hunter probe that 'dances with the Moon' will search for alien life

Nasa launches Tess: planet hunter probe that 'dances with the Moon' will search for alien lifeNasa on Wednesday blasted off its newest planet-hunting spacecraft, Tess, a $337 million satellite that aims to scan 85 percent of the skies for cosmic bodies where life may exist. "Three, two, one and liftoff!" said Nasa commentator Mike Curie as the Transiting Exoplanet Survey Satellite (Tess) soared into the cloudless, blue sky atop a SpaceX Falcon 9 rocket from Cape Canaveral, Florida at 6:51 pm (2251 GMT). The washing machine-sized spacecraft is built to search outside the solar system, scanning the nearest, brightest stars for signs of periodic dimming. These so-called "transits" may mean that planets are in orbit around them. TESS is expected to reveal 20,000 planets beyond our solar system, including more than 50 Earth-sized planets and up to 500 planets less than twice the size of the Earth, Nasa said. Its discoveries will be studied further by ground- and space-based telescopes for signs of habitability, including a rocky terrain, a size similar to Earth and a distance from their sun - neither too close nor too far - that allows the right temperature for liquid water.

"It was incredible. It was so emotional," said Natalia Guerrero, a Tess researcher at the Massachusetts Institute of Technology, in an interview on Nasa TV after the launch. She was part of a team that built four cameras that serve as the spacecraft's eyes.

They could fit in a mailbox. But they are so powerful. You could have an entire constellation, like Orion, in the field of view of one of these cameras." Tess will survey far more cosmic terrain than its predecessor, Nasa's Kepler Space Telescope, which launched in 2009. It has been a long road to launch for @NASA_TESS, the team has worked to design, assemble, test, ship the observatory over the course of the last five years. #TESSpic.twitter.com/m0dFlghJWV— NASA_TESS (@NASA_TESS) April 18, 2018 Both use the same system of detecting planetary transits, or shadows cast as they pass in front of their star. The new spacecraft will focus on nearby exoplanets, those in the range of 30 to 300 light-years away. Kepler's trove of more than 2,300 confirmed planets outside our solar was impressive, but most were too distant and dim to be examined further. "One of the many amazing things that Kepler told us is that planets are everywhere and there are all kinds of planets out there," said Patricia "Padi" Boyd, director of the Tess guest investigator program at Nasa's Goddard Spaceflight Center. "So TESS takes the next step. If planets are everywhere, then it is time for us to find the planets that are closest to us orbiting bright nearby stars, because these will be the touchstone system." The launch had previously been postponed on Monday  Credit: NASA TV The Hubble Space Telescope, launched in 1990 aboard the space shuttle, and the James Webb Space Telescope, scheduled to lift off in 2020, should be able to reveal more about planets' mass, density and the makeup of their atmosphere - all clues to habitability. The initial launch attempt Monday was scrubbed about two hours before planned takeoff, so that SpaceX engineers could perform extra checks on the rocket's navigation systems. On Wednesday, the rocket performed flawlessly. Less than 10 minutes after launch, the rocket's first stage returned to an upright landing on a drone ship in the Atlantic Ocean, marking SpaceX's 24th touchdown of a rocket booster. Nasa also confirmed that at 7:53 pm (2353 GMT), the spacecraft's twin solar arrays successfully deployed. Space exploration | Recent exciting discoveries  Tess will spend two months making its way into the correct orbit around Earth, with help from the moon's gravity, and test its instruments before its two-year mission officially begins. Its first scientific data is expected in July. "The Moon and the satellite are in a sort of dance," Joel Villasenor, instrument scientist for TESS at the Massachusetts Institute of Technology, said. "The Moon pulls the satellite on one side, and by the time TESS completes one orbit, the Moon is on the other side tugging in the opposite direction. "The overall effect is the Moon's pull is evened out, and it's a very stable configuration over many years. Nobody's done this before, and I suspect other programs will try to use this orbit later on."

"With missions like the James Webb Space Telescope to help us study the details of these planets, we are ever the closer to discovering whether we are alone in the universe."

Southwest challenged engine maker CFM over proposed FAA inspections

Southwest challenged engine maker CFM over proposed FAA inspectionsSouthwest Airlines Co clashed with engine maker CFM over the timing of proposed inspections and with regulators over costs after a 2016 accident involving the airline that was caused by a fan blade separating, public documents showed. The documents, which are on a U.S. federal website and were viewed by Reuters, reveal the wrangling over previously proposed safety checks on CFM engines that are now the focus of investigations following a fatal engine explosion this week.
