Here’s what happens. NASA also released a GIF of the various surveys Osiris-Rex carried out after arriving at Bennu in early December The series of images, captured between Nov. 30 and Dec. 31, helped the team more accurately determine Bennu’s mass, which ensured that the orbital insertion would proceed smoothly. You can see the GIF, captured by Osiris-Rex’s black-and-white NavCam, below:Enlarge ImageOsiris-Rex surveyed 101955 Bennu before slipping into orbit on December 31.  NASA/Goddard/University of Arizona/Lockheed Martin Space The orbital period, lasting until mid-February, is expected to provide additional details about Bennu’s gravity, orientation and spin, along with a better understanding of its mass. All those observations should lead to completing one of the chief objectives for Osiris-Rex: retrieve a sample from Bennu’s surface and fly it back to Earth. In 2020, the spacecraft will extend a specially designed arm, called Tagsam, for a brief high-five with the asteroid. The arm will blow nitrogen gas onto the surface of Bennu, kicking up handfuls of dirt, which the spacecraft will fly back to Earth in 2023.A successful pickpocketing will give scientists a more detailed look at the kind of compounds that make up the potentially hazardous object.Bennu is the near-Earth object that’s second most likely to collide with our planet, only outranked by an asteroid known as 1950 DA on NASA’s Palermo Technical Impact Hazard Scale. Though they’re ranked as hazardous, the actual likelihood they would ever collide with Earth is incredibly low — Bennu could smack into Earth between 2169 and 2199. 1950 DA shouldn’t trouble you at all. If it were to hit, that impact wouldn’t occur until 2880. Sci-Techcenter_img Comments Now playing: Watch this: 2 Fly, Osiris-Rex! Fly! NASA/Goddard Visiting a distant, icy world that looks like a snowman certainly had space enthusiasts enraptured in the first days of 2019, but some other historic NASA news slipped through in the final hours of 2018 — and it might reveal just as much about our solar system.The asteroid-chasing Osiris-Rex (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) performed its own historic maneuver on New Year’s Eve. An eight-second thruster burn on Dec. 31 placed the spacecraft in orbit around 101955 Bennu, which drifts through the solar system’s asteroid belt between the Earth and Mars.By inserting itself into orbit around Bennu, Osiris-Rex will survey the asteroid from a distance of only about 1 mile (1.75 kilometers) from its center. Bennu’s small size creates an incredibly tiny gravitational force, so maintaining that orbit will require lots of little adjustments, made by NASA and its collaborating organizations. “The gravity of Bennu is so small, forces like solar radiation and thermal pressure from Bennu’s surface become much more relevant and can push the spacecraft around in its orbit much more than if it were orbiting around Earth or Mars, where gravity is by far the most dominant force,” said Dan Wibben, maneuver and trajectory design lead.

Google Updates an App That Allows You to Search With the Swipe

first_img Google has rolled out an update to a mobile app that you might have never heard of but might find surprisingly useful. An app called Gesture Search can now understand swiped queries in more than 40 languages, Google announced over Google+ this week. For those of us who aren’t familiar with Gesture Search, the free app allows users of Android devices to simply draw a letter or number on the screen with the tip of a finger to access contacts, apps, music, documents and whatever else they might have stored on their Android-powered device. For instance, if you swipe the letter C, search results can turn up apps on your device such as the camera, clock of the Google Chrome browser.Gesture Search can be an alternative to the sometimes laborious task of typing on a small screen and can be far less disruptive to others than using voice control.Related: A Look at Google’s 200 Search Ranking Factors (Infographic)The app tailors itself to individual users based on their previous searches. It refines its results with each gesture the user makes. The updated app also supports transliteration, allowing users to write the way a word in another language sounds with their own alphabet.One drawback: Gesture Search only allows users to enter the first character in a search, forcing users to revert to a more traditional scrolling approach after their initial swipe.Many Android devices come preloaded with another gestural keyboard app called Swype, which allows users to compose messages in the same manner. For iOS users, there is a similar app free app called TouchPal, which also allows users to swipe their finger to compose messages instead of typing them out.This is the first significant update to Gesture Search since it was introduced as an experimental Google Labs project in 2010. Only available in the U.S., this update could foreshadow the app’s availability to a wider user base abroad.Related: Apple’s iOS 7 Includes New Design, Improved Usability   Growing a business sometimes requires thinking outside the box.

WestJet pilots union to also represent Swoop pilots says arbitrator

first_img CALGARY — A federal arbitrator has ruled that WestJet’s unionized pilots will also fly its new ultra-discount carrier Swoop that’s set to launch next week.Capt. Rob McFadyen, chairman of WestJet’s Air Line Pilots Association, says the decision means the airline can no longer outsource Swoop flying, a major disagreement in recent negotiations.Swoop will recognize the union as the exclusive bargaining agent for all Swoop pilots, who will be on the airline’s one seniority list and fly aircraft at Swoop terms and conditions.WestJet and the union will now make a joint application to the Canada Industrial Relations Board to amend pilots association’s bargaining certificate to include Swoop flying.The parties also agreed that WestJet and Swoop are common employers.The two sides scheduled mediation/arbitration dates over the summer to address all remaining issues.The threat of a strike by pilots was averted two weeks ago when the airline and union agreed to a settlement process and, if necessary, to use final and binding arbitration.More news:  Can you guess the top Instagrammed wedding locations in the world?WestJet CEO Ed Sims said it recognizes and respects the interim order that WestJet pilots should be able to operate Swoop aircraft.The Air Line Pilots Association is the largest airline pilot union in the world and represents more than 60,000 pilots at 34 airlines in the United States and Canada, including about 1,500 WestJet pilots and approximately 500 at WestJet Encore.
