Hohmann Transfer Orbit

In Andy Weir’s The Martian, NASA plans to send a supply probe to Mars to save the stranded astronaut Mark Watney through what’s called the ‘Hohmann Transfer Orbit‘.

All About Aurorae

As the title suggests, our topic for today is Earth’s aurorae (pronounced auh-ror-eye). These stunning displays generally occur in two symmetrical oval rings about the planet’s far northern and southern regions–Earth’s magnetic north and south poles. When they happen in the north, aurorae are often referred to as the northern lights or Aurora Borealis. Likewise, […] Continue reading
