Massive power outage hits Argentina, Uruguay: power companies

Massive power outage hits Argentina, Uruguay: power companies A massive outage blacked out Argentina and Uruguay Sunday, leaving both South American countries without electricity, power companies said. Uruguay's system went down at 7:06 am (1006 GMT), according to the Uruguayan power company UTE, which attributed the outage to "a fault in the Argentine network." Two Argentine power companies confirmed the failure knocked out electricity throughout Argentina, without specifying the cause. "A massive failure in the electrical interconnection system left all Argentina and Uruguay without power," Edesur Argentina said on Twitter.

Europe and Russia’ s joint robotic mission to Mars has hit a snag after the parachutes needed for The second phase will send a robotic rover, which is named after famed English chemist Rosalind Image: ESA . To touch down on Mars , the Rosalind Franklin rover is meant to ride down to the surface

The European Space Agency ( ESA ) confirmed on August 12 that another test of the parachutes that will be used on the ExoMars 2020 lander mission The next qualification attempt of the second main parachute is scheduled for early 2020. The ExoMars mission is scheduled for launch during the July

Sending a spacecraft to Mars is no easy feat, but landing it on the Red Planet without making a crater is equally challenging. The European Space Agency knows that all too well, and a recent parachute test has raised serious questions about whether the ExoMars 2020 mission will remain on schedule.

A previous test in late May showed promise but was ultimately deemed a failure due to damage sustained by the two large parachutes that will be doing the majority of the work. This latest test included an updated design of the parachute arrangement but the problem reared its head once again.

NASA gives the Mars 2020 rover its legs and wheels

NASA gives the Mars 2020 rover its legs and wheels The Mars 2020 rover is looking more and more like an actual rover, now that there's only a year left before its target launch date. NASA Jet Propulsion Laboratory engineers have installed the vehicle's starboard legs and six wheels (aka its mobility suspension) on June 13th. The machine's wheels are made of aluminum with 48 cleats machined onto their surface. 

It' s the second test mishap involving the parachutes , so with launch under a year away, the Exomars project cannot afford another failure . The European Space Agency' s ( Esa ) Rosalind Franklin rover will collect samples of soil with a drill and analyse them for the presence of organic material.

ESA said Aug. 12 another test of the parachutes that will be used on the ExoMars 2020 lander mission failed last week, putting its schedule into jeopardy. 9. ESA did not respond to a request for comment that day about the reports, instead issuing the statement confirming the test failure Aug.

The ExoMars 2020 lander is equipped with a complex parachute system that deploys in sequence to slow the spacecraft down and provide a soft landing once it reaches the Martian surface. A pair of large parachutes are pulled using smaller pilot chutes, one after the other, for a total of four parachutes deploying in sequence.

The May test went largely to plan, with all four chutes deploying in their desired sequence, but both main chutes sustained damage along the way. The same was true during the new round of testing, but ESA notes that it appears that the damage occurred prior to the larger chute fully inflating.

Poll finds Americans are worried about asteroids, don’t care about the Moon

Poll finds Americans are worried about asteroids, don’t care about the Moon As we creep closer to the 50th anniversary of the first Moon landing, NASA is doing its best to drum up support for a return mission that would see its astronauts once again roaming the lunar surface. 

The European Space Agency ( ESA ) confirmed that parachutes for the ExoMars lander mission failed a second test that was conducted last week. A similar trial conducted back in May on the same parachutes also ended up malfunctioning. Scientists observed damages in the canopy in both cases.

ESA . Those two parachutes each have a smaller pilot chute that helps deploy the bigger chutes, one of which would be the largest ever flown on a Mars mission with ExoMars team leader Francois Soto described the test failure as "disappointing." Mars parachute experts from ESA and NASA will help

“It is disappointing that the precautionary design adaptations introduced following the anomalies of the last test have not helped us to pass the second test successfully, but as always we remain focused and are working to understand and correct the flaw in order to launch next year,” ESA’s Francois Spoto said in a statement. “We are committed to flying a system that will safely deliver our payload to the surface of Mars in order to conduct its unique science mission.”

The ExoMars 2020 team will now go back to the drawing board and attempt to design a solution to the problem. The lander and rover riding along with it are rugged machines, but a crash landing would obviously bring an abrupt halt to everything ESA has planned for the mission.

With the mission scheduled for a launch in late July or early August of 2020, ESA will need a bit of good luck to ensure it makes the date will a fully functional and well-tested parachute system.
