Could Ukraine war spread to space and endanger satellites?

Could Ukraine war spread to space and endanger satellites?

Despite conflicts on Earth, satellites orbit in peace. But use of Elon Musk’s Starlink to aid Ukraine has Russia looking to the sky with hostile eyes. A rocket booster carrying three Gonets-M satellites and the first Skif-D satellite of the Sfera programme lifts...

While all kinds of international conflicts occur on the ground, up in space things have been pretty peaceful. We depend on peace in the skies because such things as social media, multiplayer video games, Google classrooms and Zoom sessions rely on satellites bouncing signals across the earth. Correspondent Tira Shubart tells us why tensions on the ground in Ukraine could disturb the tacit and explicit agreements over satellites in the sky. 

Exercise: Let’s imagine that each student has been hired to draw up an international agreement to govern and protect satellites that need to cross the skies over international borders. What are the five most important considerations that would have to be included in this treaty? Some things to consider are: The citizens in every country want fast and reliable Internet; people want their privacy protected; and countries are concerned about the possible military use of satellites.

Decoder: With Artemis, US aims to return humans to the Moon

It’s been 50 years since humans walked on the Moon. Now, the U.S. is launching a costly program to return there and possibly pave the way to Mars. NASA’s Space Launch System rocket with the Orion spacecraft aboard at NASA’s Kennedy Space Center in Florida,...

Five decades after humans walked on the Moon, the U.S. space agency NASA is leading an international endeavor to return there at a cost of $93 billion. Correspondent Natasha Comeau decodes the Artemis project, a series of missions to build a long-term human presence on the Moon. The 21 nations that have signed the Artemis Accords for space exploration reflect today’s political divisions. Missing from the collaboration are China and Russia, which plan to build a lunar station of their own. It was competition with the then Soviet Union in the 1960s that spurred the first space race and resulted in the historic 1969 moon landing. Now, a host of private corporations are funding their own space initiatives.

Exercise: In teams, have students form their own private space exploration company. Were they able to successfully build their own rocket that could take people into space, what would be their mission? What would they hope to get out of their space exploration ventures? Have each team come up with three things they think space missions could accomplish.

Decoder: Crypto currencies, good or bad, are here to stay

They can fluctuate wildly in value. They can be hard to spend. They devour energy. But crypto currencies are here to stay and will surely bring changes. Photo by STRF/STAR MAX/IPx 2021 1/21/21, courtesy of AP Photos In the past few weeks, an iconic Los Angeles sports...

News Decoder is committed to explaining, in simple terms, complicated stories that appear over and over on front pages and in news broadcasts. For lack of time, money and space, most mainstream news organizations don’t take the trouble to explain the background to complicated issues and assume readers and viewers understand why the story matters. How many of us say to ourselves when running across a story on crypto currencies: “I need to educate myself about these things because they are not going away.” In his decoder, Stuart Grudgings explains how crypto currencies emerged, how they work and why they are with us to stay.

Exercise: Ask students to debate whether crypto currencies will eventually replace traditional money.
