Hanneke Weitering, staff writer for Space.com, breaks down what could go wrong or right during SpaceX's Falcon Heavy launch. The company is planning on launching the rocket from the Kennedy Space Center Tuesday after years of delay.
Weitering says the Falcon Heavy is a "big, awesome rocket" that could eventually take passengers to the moon or even Mars. It was originally set to launch in 2013.
Weitering explains the Falcon Heavy launch is a big deal for space exploration, since the rocket can be reused. The test payload for the rocket is Elon Musk's original Tesla Roadster.
The planet's temperature spiked on Tuesday to its hottest day in at least 44 years and likely much longer, and Wednesday could become the third straight day Earth unofficially marks a record-breaking high, the latest in a series of climate-change extremes that alarm but don't surprise scientists.
The only break much of America can hope for anytime soon from eye-watering dangerous smoke from fire-struck Canada is brief bouts of shirt-soaking sweltering heat and humidity from a southern heat wave that has already proven deadly, forecasters say.
