Zhurong Rover dropped Camera on Mars to make group photos at Utopia Planitia (Chinese Tianwen-1)

On June 11, 2021 CNSA published new Hi-Res Mars images Zhurong Rover (Chinese Tianwen-1 mission) with amazing details of Utopia Planitia on Red Planet. Rover dropped/deployed special instrument camera to make group images. Camera made first shot capturing Mars Lander and Zhurong Rover together in single frame. Resolution of the images is incredible. Chinese Zhurong Mars Rover has been working on the surface of Mars for 26 Martian days, carrying out environmental perception, fire surface movement, and scientific exploration. Zhurong also made first panoramic 360 degrees image at Utopia Planitia on Mars. There is image of Parachute pack and Heat Shield on the surface of Red Planet.

This Drone Bus Will Carry 40 Passengers Between Cities for the Price of a Train Ticket

He’s got a point. There’s a lot more space in the sky than on the ground, obviously, but flight paths need to be carefully planned and contained within specific areas, particularly in and near big cities. If flying taxis became affordable enough for people to use them the way we use Uber and Lyft today, there would quickly be all sorts of issues with traffic and congestion, both in the sky and with takeoff and landing space on the ground. So why not take a scaled approach from the beginning?

Speaking of affordability, Kelekona says that’s a priority, too. It may play out differently, especially in the technology’s early stages, but the intention is for tickets on the drone bus to cost the same as a train ticket for an equivalent distance. The first route, from Manhattan to the Hamptons, will reportedly have a 30-minute flight time and an $85 ticket price.

Other intended routes include Los Angeles to San Francisco, New York City to Washington DC, and London to Paris—all in an hour, which is comparable to the time it takes for a regular flight right now. One of the differences, ideally, will be that the eVTOLs will be able to land and take off closer to city centers, given that they won’t require long runways.

Seraphim Capital unveils worlds first listed space technology fund

TAMPA, Fla. — Seraphim Capital plans to trade stakes it has amassed in space technology startups on the public market through an investment trust.

The Seraphim Space Investment Trust will eventually comprise bets in 19 international startups, including satellite data specialist Spire Global, quantum encryption firm Arqit and space-based cellular network operator AST Space Mobile.

Those three recently got valuations of more than $1 billion in mergers with special purpose acquisition companies (SPACs), investment vehicles that offer another route to public markets.

Say goodbye to your camera bump: Miniaturized optics through new counterpart to lens

ANOTHER OPTICAL BREAKTHROUGH COMPLEMENTING METALENSES. In addition to the ongoing revolution in optical science brought about by flat metalenses and single-photon image sensors, there is another parallel and complementing new dimension now added to the mix, which, according to this article, will allow telescopes as thin as a piece of paper.

Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone?

In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives.

To learn more about this project, we talked to lead author Dr. Orad Reshef, a senior postdoctoral fellow in the Robert Boyd Group, and research lead Dr. Jeff Lundeen, who is the Canada Research Chair in Quantum Photonics, Associate Professor in the Department of Physics at the University of Ottawa, and head of the Lundeen Lab.

New connector for sustainable structures on Earth and in space

As part of his Master’s degree in civil engineering, an EPFL (Ecole Polytechnique Federale de Lausanne) student developed a connector for use in building sustainable structures. His initial project has expanded into an online program for designing bamboo furniture that’s stylish, modular and customizable. And now his connector is being looked at for use by astronauts in outer space.

During his time at EPFL under the Erasmus program, Romain van Wassenhove came up with an idea for a connector that could be used to make modular structures out of sustainable rather than wood, plastic or metal. “I wanted to focus my Master’s on a topic that had meaning to me and that would lead to a concrete application,” he says. “Working with bamboo was something I already had in mind while I was studying in Brussels.” His connectors can be 3D-printed in biosourced plastic and are customizable to the type of material used for the structure.

Van Wassenhove got the idea for his connector during a class at EPFL on composite materials and developed the concept further through his Master’s project, co-directed at EPFL by Senior Scientist Anastasios Vassilopoulos and by associate professor Lars De Laet at Vrije Universiteit Brussel (VUB). In September 2020, soon after graduating, he obtained research funds—through an EPFL Ignition Grant—to enhance the design and operation of his connector and test it on an initial application involving bamboo structures. Today van Wassenhove’s invention is EU patent-protected, and his research has just been published in Composite Structures.
