On 23 July 2021, the world watched as the long overdue and somewhat subdued opening ceremony of the 2020 Summer Olympic Games got underway in Japan — and while not the greatest show on Earth this year, it certainly delivered the greatest Earth on show, for it was the day the Earth appeared over Tokyo. …
On 11 July, 2021, Sir Richard Branson, founder of Virgin Galactic, took a suborbital flight to the inner edge of outer space, reaching an altitude of 86 km (54 miles) above the surface of the Earth. Although it marked a milestone for space tourism, where that milestone marker should be placed is an ongoing matter …
NASA and Arizona State University, along with other partners, are working on a project to send a spacecraft to investigate the unique asteroid 16 Psyche, an assumed metal-rich body about the size of Switzerland orbiting in the asteroid belt at an average distance of 2.9 AU from the Sun.
