Planning for a full-scale interstellar probe architecture. The long and winding road to Alpha Centauri.
To be successful, interstellar probes will need more than speed.

(Phys.org)—Researchers have built the first robot made of soft, deployable materials that is capable of moving itself without the use of motors or any additional mechanical components. The robot “walks” when an electric current is applied to shape-memory alloy wires embedded in its frame: the current heats the wires, causing the robot’s flexible segments to contract and bend. Sequentially controlling the current to various segments in different ways results in different walking gaits.
The researchers expect that the robot’s ability to be easily deployed, along with its low mass, low cost, load-bearing ability, compact size, and ability to be reconfigured into different forms may make it useful for applications such as space missions, seabed exploration, and household objects.
The scientists, Wei Wang et al., at Seoul National University and Sungkyunkwan University, have published a paper on the new robot and other types of deployable structures that can be built using the same method in a recent issue of Materials Horizons.

Sat 17 June…NASA rocket to blast colored clouds into space…similar to our 2017 SpaceApps Groups Idea : https://2017.spaceappschallenge.org/challenges/warning-dange…er/project
- NASA is launching a rocket that will create colorful clouds in space.
- The rocket launch and clouds may be visible as far away as New York City.
- Such clouds will eventually be used to probe two big holes in Earth’s magnetic shield, called cusps.
- The launch will be live-streamed by NASA Wallops Flight Facility.
NASA is about to launch a rocket that will puff out highly visible clouds of red and blue-green vapor into space.
The rocket was supposed to launch on May 31, but bad weather and poor visibility pushed the mission back to Saturday, June 17, with a liftoff time between 9:05 p.m. and 9:20 p.m. EDT.
Chinese researchers report that they’ve set a new distance record for quantum teleportation through space, the phenomenon that Albert Einstein once scoffed at as “spooky action at a distance.”
The technology isn’t yet ready for prime time, but eventually it could open the way for a new type of unbreakable encryption scheme based on the weirdness of quantum physics.

What is CTA and how will it work? This video produced by CTA Consortium member Deutsches Elektronen-Synchrotron (DESY) explains how CTA will look at the sky in higher energy photons than ever measured before and give a behind the scenes look at the construction of a prototype of one of the proposed telescopes, the Medium-Size Telescope.

As part of of ESA’s 268th council on 13 June, Urve Palo, Minister of Entrepreneurship and Information Technology of the Republic of Estonia, and Jan Woerner, ESA Director General, digitally signed a Memorandum of Understanding on Information and Communications Technology collaboration. It is the first digital signature performed at ESA.
“I am happy to see that the digital signature has found its way to the European Space Agency,” noted Ms Palo. “I and every other Estonian use it on a daily basis, saving up to five working days per year by this solution.”
“Estonia is proud to share its experience in digital management and e-governance with ESA and to contribute with this strength to the evolution of the European Space 4.0 endeavour. The next step would be to take e-state solutions to space and be part of the development of the Moon Village.”
