Mars will shine in the sky on Tuesday night as the planet lines up with Earth, looking big and bright as it reaches “opposition”.

Every 26 months, the two planets move close together, until Earth lines up with Mars on the same side of the sun. 

Tuesday night sees the moment of opposition, with the planets lining up at just after 11pm. 

At that point, Mars should be visible to the south east from the UK, astrophotographer Damian Peach told the BBC. 

Peach said, “Even at nine or 10 o’clock in the evening, you’ll easily see it over in the southeast. You can’t miss it, it’s the brightest star-like object in that part of the sky.”

The Red Planet actually made its closest approach to our planet on 6 October, when it was 38,586,816 miles away from Earth

Astra’s 1st orbital test launch fails during first-stage engine burn

Astra’s first orbital mission got off the ground, but it soon came back down again.

Astra’s Rocket 3.1 rises into the sky above Alaska’s Pacific Spaceport Complex during the company’s first orbital launch attempt on Sept. 11, 2020. The flight ended during the first-stage engine burn.

The California-based spaceflight startup launched its first orbital test flight tonight (Sept. 11), sending its two-stage Rocket 3.1 skyward from the Pacific Spaceport Complex in Alaska at 11:20 p.m. EDT (7:20 p.m. local Alaska time and 0320 GMT on Sept. 12).

The 38-foot-tall (12 meters) booster, which was carrying no payloads, didn’t make it all the way to the final frontier.

“Successful lift off and fly out, but the flight ended during the first-stage burn. It does look like we got a good amount of nominal flight time. More updates to come!” Astra tweeted tonight.

Bio-inspired zinc battery could change how robots burn energy

More and more robo-tech is evolving in an ironic turn that goes against many of the cold metal worlds in science fiction, where flesh has been taken over by machine. Maybe the most unexpected biomimetic — literally mimicking biological creatures — technology is a robot battery that stores energy like fat.

Sorry, Baymax, but robots will actually lose weight with a new “fat battery” (tech throughout history has often shed bulk with each upgrade). University of Michigan professor Nicholas Kotov — a professor of chemical engineering, materials science and engineering, and macromolecular science and engineering — has developed a zinc battery that could really level up the function of everything from nurse and server droids to delivery drones to micro- and nanobots. Smaller but much more energy-dense than the typical lithium ion battery, it can power a robot just as biological fat reserves can keep us going.

“Such multifunctional batteries
