Sustainable New Material for Carbon Dioxide Capture

In a joint research study scientists have developed a new material for capturing carbon dioxide. The new material offers many benefits -- it is sustainable, has a high capture rate, and has low operating costs.
The new material is a bio-based hybrid foam, infused with a high amount of CO2-adsorbing 'zeolites' -- micro porous alumino silicates. This material has been shown to have very promising properties. The porous, open structure of the material gives it a great ability to absorb the carbon dioxide.

SpaceX Delivers Mice, Worms and Robot to Space Station

SpaceX made an early holiday delivery to the International Space Station (ISS), bringing muscle-bound "mighty mice," pest-killing worms and a smart, empathetic robot.
The station commander, Italy's Luca Parmitano, used a large robot arm to grab onto the Dragon three days after its launch from Cape Canaveral.
The two spacecraft soared 420 kilometers above the South Pacific at the time of capture.
It marks the third visit for this recycled Dragon. Flight controllers quickly secured the capsule to the orbiting lab, paving the way for the hatch to open and the unloading to begin. The capsule holds 3 tons (2,720 kilograms) of supplies, including 40 mice for a muscle and bone experiment.
There also are 120,000 roundworms, or nematodes of a beneficial variety that are part of an agricultural study aimed at controlling pests here on Earth.
The capsule also has a large, round robot head with artificial intelligence and the ability to sense astronauts' emotions. Named Cimon, it's an improved version of what flew up in 2018 to be tested as an astronaut's helper.

ISRO to Launch RISAT-2BR1 Surveillance Satellite

Indian Space Research Organisation (ISRO) is preparing to launch an earth observation satellite named RISAT-2BR1 from the Satish Dhawan Space Centre in Sriharikota on December 11, 2019.
The RISAT-2BR1 is the second satellite in the RISAT-2B series and the launch of this satellite will boost the capability of Indian security agencies to carry out the surveillance of earth from the space.
ISRO had launched the first satellite in the RISAT-2B series on May 22, 2019 to replace the ageing RISAT-2.

NASA's Solar Mission Sends Spectacular Data Trove

NASA's Parker Solar Probe, having survived its closest encounter so far with the Sun, sent back a spectacular trove of data on its corona, the super-hot outer edge of its atmosphere.
The car-sized probe, launched in August 2018, will come within some six million kilometres of the Sun's surface during a series of fly-bys at other distances and trajectories over seven years.
It is hoped it will allow a better understanding of the solar wind and electromagnetic storms, which can cause chaos on Earth by knocking out the power grid.

Mars Rover Hopes to Grab a Piece of History

British engineers have begun testing technologies that will be needed to bring samples of Martian rock to Earth.
The Airbus team is training a prototype rover to recognise and pick up small cylinders off the ground.
It's a rehearsal for a key part of a multi-billion-dollar project now being put together by the US and European space agencies - NASA and ESA.
Returning rock and dust materials to Earth laboratories will be the best way to confirm if life exists on Mars.
