Earth records its shortest day
This summer, the Earth had its shortest day ever as a result of an axis wobble that caused it to complete one spin in just a few hundredths of a second less than 24 hours.
According to the website timeanddate.com, 29th June 2022 was 1.59 milliseconds shorter than a full day, which is exactly 86,400 seconds. In recent decades, the Earth has slowed down, resulting in slightly longer days.
However, in recent years, this trend has changed, and the days have become increasingly shorter. If the trend continues, scientists may be forced to create the first ever negative leap second in order to keep our clocks in sync with the planet’s rotation.

NASA to host briefings about Artemis 1
On August 29, NASA is scheduled to launch Artemis 1, an unmanned deep-space test flight using its Orion spacecraft and enormous Space Launch System megarocket. It will be the agency’s first big step in the Artemis program.
The Artemis program is a NASA-led human spaceflight initiative to explore the Moon, with a target date of 2024 for the first landing on the lunar south pole. If the Artemis program is successful, it will conduct the first crewed lunar landing mission since Apollo 17, the final crewed mission of the Apollo program, in December 1972.
NASA will hold a mission overview briefing on Wednesday, August 3, and a detailed mission briefing on Friday, August 5. You can watch both events for free online on NASA’s website.
