SpaceX scrubbed the launch of a Falcon 9 rocket after delaying a Falcon Heavy launch for the U.S. military. It had planned the launch Monday night, less than three hours after the scheduled launch of a Falcon Heavy from nearby pad 39A. Liftoff of the Falcon 9 with 23 Starlink satellites was tentatively rescheduled for 11:02 p.m. EST (0402 UTC) Tuesday.

One of the chief objectives of the James Webb Space Telescope (JWST) is to study the formation and evolution of the earliest galaxies in the Universe, which emerged more than 13 billion years ago. To this end, scientists must identify galaxies from different cosmological epochs to explore how their properties have changed over time. This, in turn, requires precise dating techniques so astronomers are able to determine when (in the history of the Universe) an observed galaxy existed. The key is to measure the object’s redshift, which indicates how long its light has been traveling through space.
NASA’s Psyche mission began eight weeks ago when it launched from the Kennedy Space Center. While it won’t reach its objective, the metal-rich asteroid Psyche, until 2029, the spacecraft has already travelled 26 million km (16 million miles.) During that time, it’s already had its share of success as it ticks off items on its checklist of tests.

Now that several decades have passed since the launch of Voyager 1 and Voyager 2 in 1977, we look back on that time with a hazy sense of history and what the event meant for humanity’s ongoing odyssey. While the Voyager spacecraft were sober scientific missions, they also carried with them a hint of the deeper yearnings that lie inside humanity’s heart: the Golden Records.
