There’s reason to be optimistic about Mars Opportunity rover that has been silent since June 10, after getting caught in a massive dust storm on the Red Planet that cut off solar power for the nearly 15-year-old rover, NASA said in a statement.

According to the scientists, the global dust storm is “decaying” — meaning more dust is falling out of the atmosphere than is being raised back into it. As a result, skies might soon clear enough for the solar-powered rover to recharge and attempt to “phone home.”


Studies on the state of batteries and temperatures at the location showed that they were relatively in good health before the storm, and there is not likely to be too much degradation.

Moreover, because dust storms tend to warm the environment — and the storm happened in summer — the rover should have stayed warm enough to survive, the US space agency noted.

Engineers at NASA’s Jet Propulsion Laboratory in California are now looking for signs for recovery efforts.

According to them, Opportunity will need a tau — the veil of dust blowing around — of less than 2.0 before the solar-powered rover will be able to recharge its batteries.

The higher the tau, the less sunlight is available; the last tau measured by Opportunity was 10.8 on June 10. To compare, an average tau for its location on Mars is usually 0.5.

Several times a week, the engineers are using NASA’s Deep Space Network, which communicates between planetary probes and Earth, to attempt to talk with Opportunity.

The massive DSN antennas ping the rover during scheduled “wake-up” times, and then search for signals sent from Opportunity in response.

In addition, JPL’s radio science group uses special equipment on DSN antennas that can detect a wider range of frequencies. Each day, they record any radio signal from Mars over most of the rover’s daylight hours, then search the recordings for Opportunity’s “voice.”

However, even after the first time engineers hear from Opportunity, it would take time to fully recover, NASA said. (IANS)

Union Finance Minister Nirmala Sitharaman on Saturday asked the Directorate of Revenue Intelligence (DRI) to prevent dumping of toxic wastes in India.

Union Finance Minister Nirmala Sitharaman on Saturday asked the Directorate of Revenue Intelligence (DRI) to prevent dumping of toxic wastes in India. Speaking at an event to celebrate DRI's 64th foundation day, Sitharaman lauded DRI's compact strength of about 800 officers for their relentless efforts despite the imminent risks. The Finance Minister stated that the officers may be keeping a low profile, but they are acting like the frontline defence forces, doing spectacular work in safeguarding the economic frontiers of the country. "The recent smuggling attempts of huge quantities of narcotics, gold, red sanders, ivory, cigarettes etc. unearthed by DRI were appreciated by the Finance Minister," the Ministry of Finance said in a statement.

"Sitharaman said that the message through such enforcement actions should be such that these acts of brazen attempts at smuggling are nipped in the bud," the statement added. The Finance Minister also said that better coordination among the law enforcement and intelligence gathering agencies and sharing of actionable intelligence are the way forward in protecting the frontiers of the country more efficiently. "Sitharaman also asked the DRI to focus on interdicting dual use technology items as well as preventing the dumping of toxic wastes in our country," the statement said. (IANS/ MBI)

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features.

Tech giant Amazon has expanded the sound detection capabilities of Alexa along with more features. Alexa can now identify the sounds of running water and appliances beeping, reports Android Central. This means users can set up an Alexa routine to notify themselves when the washer beeps to indicate that laundry is finished, the report said.

When Alexa detects that the faucet has been left open, it will send users a notification as well so they can take appropriate action, it added. Amazon previously said at its event in September that it would add the ability to programme Alexa to recognise custom sounds, but that feature has yet to arrive. Having said that, the two new sound detection capabilities not only help users save energy, but they also make it easier to avoid paying for unnecessary charges on your home utilities, the report said.

The retail giant has also announced ultrasound motion detection, which will allow you to set up "Occupancy Routines" on additional Echo devices. This feature allows your smart speaker to detect nearby motion and initiate a routine, such as turning on the lights. It is compatible with many of the best Alexa speakers including the 4th-gen Echo, Echo Dot and Echo Dot with Clock. (IANS/ MBI)
