Less than a century ago, astronomers relied entirely on ground-based observations to further scientific study. Today, descendants of that first liquid-fueled rocket provide eyes on cosmic phenomena, unravel mysteries of the early universe, and even take a closer look at what makes our own planet tick. None of this would be possible without the experiments of Massachusetts physics professor Robert Goddard, best known for inventing the liquid-fueled rocket. The namesake of NASA’s Goddard Space Flight Center (nasagoddard), he dreamed as early as 1909 of creating an interplanetary vehicle. While he couldn’t achieve that in his lifetime, his inventions in the first half of the 20th century became the engineering foundation for the rockets that first took humans to the moon in the 1960s and for today’s rockets, which look further into space than ever before, on a #journeytomars, and beyond. Shown here, employees at Goddard recreated the first liquid-fueled rocket launch in front of Building...
