Vacuum-sealed container from the 1972 Apollo 17 Moon landing will soon be opened for the first time

Gizmodo »

Recognizing that future scientists will have better tools and richer scientific insights, they refrained from opening a portion of the lunar samples returned from the historic Apollo missions. One of these sample containers, after sitting untouched for 50 years, is now set to be opened.

The sample in question was collected by Gene Cernan in 1972. The Apollo 17 astronaut was working in the Taurus-Littrow Valley when he hammered a 28-inch-long (70 cm) tube into the surface, which he did to collect samples of lunar soil and gas. The lower half of this canister was sealed while Cernan was still on the Moon. Back on Earth, the canister was placed in yet another vacuum chamber for good measure. Known as the 73001 Apollo sample container, it remains untouched to this very day.

But the time has come to open this vessel and investigate its precious cargo, according to a European Space Agency press release. The hope is that lunar gases might be present inside, specifically hydrogen, helium, and other light gases. Analysis of these gases could further our understanding of lunar geology and shed new light on how to best store future samples, whether they be gathered on asteroids, the Moon, or Mars.

The Canadian Space Agency (CSA) is preparing for a Canadian rover to explore a polar region of the Moon within the next five years. Two Canadian companies, MDA and Canadensys, have been selected to design lunar rover concepts.

The mission will demonstrate key technologies and accomplish meaningful science. The rover will carry at least two science instruments. Its mission will aim to gather imagery, measurements, and data on the surface of the Moon, as well as to have the rover survive an entire night on the Moon. Lunar nights, which last about 14 Earth days, are extremely cold and dark, posing a significant technological challenge.

The Lunar Exploration Accelerator Program (LEAP) prepares Canada’s space sector for lunar exploration by offering a wide range of opportunities for Canadian science and technology activities in lunar orbit or on the Moon’s surface.

Amazon to launch first two Internet satellites in 2022 to compete with SpaceX

NY Times »

The first two prototype satellites from Project Kuiper, the internet-from-space venture from the e-commerce giant, are scheduled to launch in the fourth quarter of 2022, Amazon announced on Monday. That will formally kick off its competition with SpaceX, the space company owned by Elon Musk, and OneWeb, among other rivals, for beaming high-speed internet connections to customers from low Earth orbit. It will also be a crucial test of the satellites’ design before the company launches thousands more devices into orbit.

Amazon first announced its goal of deploying a constellation of 3,236 satellites in low Earth orbit in 2019. This was the second pursuit in space by Jeff Bezos, Amazon’s founder and former chief executive who also owns Blue Origin, the rocket company. A handful of other firms are also racing to offer high-speed internet to governments, other companies and consumers whose access is hampered by the digital divide in remote locations.

Like SpaceX, Amazon plans to spend $10 billion on the project, which sits within its devices unit. But the company has been slower to start than SpaceX, whose Falcon 9 rockets have lofted nearly 2,000 internet-beaming satellites into orbit for its own venture, Starlink. Thousands of customers are testing the SpaceX service for $99 a month with $499 antenna kits.

Video » Satellite images show the change in the Arctic

European Space Agency, ESA via YouTube »

Satellites images from space play a vital role in monitoring the rapid changes taking place in the Arctic. Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate. Currently more than a trillion tonnes of ice is lost each year. The sooner Earth’s temperature is stabilized, the more manageable the impacts of ice loss will be.
