Encounter the Faith and Wisdom of C.S. Lewis
C.S. Lewis’s writings bring the great questions of the Christian faith to life. Through his imaginative and invigorating style, Lewis answers these questions in ways that are compelling to those outside Christianity and energizing to those within the Christian faith.

In this free, seven-lecture course, Professor Michael Ward—a leading scholar of C.S. Lewis—will explore Lewis’s:

Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future. //

Such interference patterns happened mostly on Tuesdays, Wednesdays, and Thursdays during business hours in Europe, Humphreys told the YouTube channel Veritasium. Because such “continental-scale” interference was simultaneously affecting GPS receivers across Europe and beyond, Humphreys and his colleagues calculated that the source had to be at least 1,200 kilometers above the Earth. //

But Russia has been demonstrating a growing number of systems that can potentially neutralize space-based assets belonging to the United States and Europe. In April 2026, the leader of US Space Command warned that Russia had operationalized anti-satellite weapons capable of targeting US government satellites. In May 2026, open source orbital tracking data revealed that at least four Russian military satellites performed orbital maneuvers to match the orbit of a Finnish-American radar surveillance satellite.

Mission Commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen (the latter with the Canadian Space Agency) spent 10 days in early April flying by the Moon. Their journey took them farther away from Earth than any humans have gone (52,756 miles [406,771 km]) and then, on the way back on board their Orion spacecraft Integrity, they sped up to about 24,664 miles per hour (39,693 k/ph) reentering the atmosphere.

Only three other people in history have traveled faster. NASA’s Apollo 10 astronauts Thomas Stafford, John Young, and Eugene Cernan set the record for the highest speed attained by a crewed vehicle relative to the Earth’s surface: 24,791 mph (39,897 kph) on May 26, 1969.

Cernan died in 2017, Young in 2018, and Stafford in 2024.
