Hope dwindles as NASA’s Opportunity rover refuses to contact Earth

  Hope dwindles as NASA’s Opportunity rover refuses to contact Earth Time flies when you're trying to message a rover that just won't wake up. The rover, which is over a decade and a half old at this point, was only supposed to last a few months on the Martian surface. It’s since spent over 14 years on the Martian surface, and the original mission timeline has been extended again and again as the rover proved it was up for additional work, but now it’s looking more and more like it might be the end of the road.

There’s a lot of incredibly specific planning that goes into a mission to another planet, and Mars will give scientists and engineers a long list of challenges to overcome, but there’s one thing that no planet-hopping expedition could do without: a heat shield.


Mankind doesn’t have a whole lot of interest in visiting planets without atmospheres — at least not yet — and when a spacecraft makes its descent to a new planet’s surface they’ll have to deal with the intense friction between the ship and the various gasses that surround the planet. With all that in mind, NASA debuted an entirely new kind of heat shield this week, and it might be a perfect fit for future missions to Mars and beyond.

  NASA’s Curiosity rover just snapped a stunning 360-degree panorama of Mars NASA's Opportunity rover might be taking an extended nap at the moment (please don't say it's dead!) but the Curiosity rover is wide awake and doing a whole bunch of science stuff. The image, which is a bit distorted near the bottom due to the quirks of taking a panorama with the rover’s own body in the frame, is a timely reminder of just how harsh the conditions on the Red Planet are.

A manned mission to Mars is (very) slowly coming together for the folks at NASA . There's a lot of incredibly specific planning that goes into a mission to another planet, and Mars will give scientists and engineers a long list of challenges to overcome, but there's one thing that no planet-hopping.

Keeping that in mind, NASA has launched a new type of heat shield this week, and could perfectly suit future missions on Mars and beyond. NASA tested the new heat shield this week Mexico and followed the deployment of the shield at the start of the rocket. The group did not offer much detail as

As Reuters reports, the new heat shield is called ADEPT, which stands for Adaptable Deployable Entry Placement Technology. That’s just a very fancy way of saying that it’s a heat shield that physically unfolds when needed. The shield, which would be situated on the front of a spacecraft as it enters a planet’s atmosphere, opens like a flower and blocks the intense heat from damaging or destroying the ship itself.

What makes this so special is that, up until now, heat shields were static components of a spacecraft. The entire rest of the spacecraft typically has to be built with the heat shield in mind, and that puts some serious limits on how a manned ship could be designed. With a deployable shield, the ship can essentially be whatever its designers want it to be, and the shield can be deployed to do its job whenever it’s needed.

The clock is now officially ticking on NASA’s sleeping Opportunity rover

  The clock is now officially ticking on NASA’s sleeping Opportunity rover Even if you aren't particularly interested in space or science news you've probably heard about the plight of NASA's Opportunity rover. That was in early June, and even though the skies above the rover have become bright again there’s been no sign that the rover has woken back up. Now, with hope and patience both dwindling, NASA has officially started the countdown to declaring the rover officially dead.

NASA tests foldable heat shield that could help human Mars landing : NASA explains why its "At the larger scales, it could be used for something as grand as human Mars explorations, or potentially human cargo landings on Mars ," Smith told Reuters at the Spaceport America launch site, about 50

Engineers at a NASA facility have tested a prototype foldable heat shield by blasting it with a flow of heated air – an environment it would Landing on Mars is a big technical challenge. For instance, to place the Curiosity rover on the Red Planet, NASA used a combination of a heat shield , a parachute

NASA tested the new heat shield this week, launching its test rocket from New Mexico and monitoring the deployment of the shield as the rocket made reentry. The group hasn’t offered much in the way of details as to how the test went, but that information will be released once NASA has a chance to examine the hardware that made it back to Earth.

Flip phones are coming back in style - but with a twist .
In less than a year, you could have a flip phone back in your pocket. The rumors that have been circulating about the development of a smartphone with a foldable screen by Huawei have been confirmed by the company's deputy chairman, Ken Hu at the World Economic Forum in China this week, according to Forbes. By mid-2019 this new-generation flip phone will be available for purchase.
