NASA drops spacecraft into orbit around potentially hazardous asteroid Bennu

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.

David Carnoy/CNET When Microsoft released its Surface Headphones last year, I thought it might have trouble selling its first noise-canceling headphones for the same price — $350 — as highly regarded competing products from Bose and Sony. Well, now Microsoft has chopped the price on the Surface Headphones by $100, bringing them down to $250.It’s unclear how long the deal will last but the headphones are $250 at both Amazon and at the Microsoft Store. They’re great headphones, but I gave them a 3.5-star rating partially because they cost a little too much.

Security glitch Mamatas chopper loses way near BdeshNepal border

first_imgKolkata: Major security lapses were detected when Chief Minister Mamata Banerjee’s chopper reached almost 50 minutes behind schedule at the rally ground in Chopra on Wednesday.According to sources, On Wednesday afternoon, Banerjee’s chopper took off from Bagdogra Airport at Siliguri to go to Chopra. The distance between Chopra and Bagdogra is about 15 minutes. But after almost 20 minutes went by, Banerjee and her co-passengers sensed that something was not right.

He had initially thought of returning to Bagdogra Airport, but later decided to land somewhere else. Sources informed that during the whole imbroglio, the pilot was worried that he had accidentally entered the Bangladesh airspace, which is close to Chopra. Nepal airspace is very close to the area as well. In the midst of the confusion, the chopper kept on flying for almost 50 minutes. Later, some of the passengers found mobile network and was able to detect the location. Later, the chopper landed safely with Banerjee and the others reaching almost 55 late from the scheduled landing time.

An airplane is guided by the Air Traffic Control, whereas a chopper follows the Visual Flying Rules which means it will fly according to visibility. Also, to land a chopper, the pilot needs a proper signal from the landing point. In this case, the pilot specifically alleged that he did not see any signal such as smoke signal or light signal (used at night) from the landing point. Subsequently, questions arose on whether the persons on duty at the landing point were aware of the chopper taking off from Bagdogra and if they were aware of it, why no smoke signal was given to the chopper pilot.last_img read more

A Gadget That Detects Gluten With 4 Million in Funding This Startup

first_img 6SensorLabs is on a mission to help people with food allergies worry less when they go out to eat. And it just got a bit closer to that goal.The San Francisco-based company raised $4 million in seed funding this week from Upfront Ventures, Lemnos Labs, SK Ventures, SoftTech VC, Mitch Kapor and Xandex Investments.Founded by CEO Shireen Yates and CTO Scott Sundvor, the company has been hard at work developing a portable sensor that will identify gluten in food (we wrote about them here back in July). Yates says the funding will be used to optimize technology and launch the final product. The company hopes to bring the sensor to market in early 2015.Related: 3 Culinary Startups Heating Up the Food IndustryThe sensor is still in development, and so far there are no firm details on its pricepoint, but the goal is for it to be marketed for affordable and personal use. There will also be an accompanying mobile app where users can report the results of the testing as well as share their restaurant experiences to help others who are avoiding gluten for health reasons. The company is starting with gluten, but plans to expand to other allergens.  Related: Investors Are Hungry for Food Startups  2 min read Register Now » Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right.center_img Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals September 12, 2014last_img read more
