50 years after Apollo, NASA tries crewed mission to Moon again. Here’s why Artemis II matters

Artemis II will be the first human mission beyond low-Earth orbit since Apollo 17 in 1972. Over the course of an approximately 10-day flight, four astronauts will travel around the Moon and return to Earth, venturing farther from the planet than any crew in more than five decades.

According to Williams, advances in video conferencing technology — especially after its widespread adoption during the COVID-19 pandemic — have made staying in touch easier for astronauts.

Williams also said astronauts avoid driving immediately after their return, as reaction times may be slower during the initial recovery phase.

Isro’s PSLV-C62 mission fails, second rare setback in eight months for workhorse launcher

Trouble emerged after the ignition of the third stage. Mission control lost telemetry shortly thereafter, confirming that the rocket failed to achieve orbital insertion, a setback that closely resembled the PSLV-C61 failure reported last year

At its most basic, space insurance transfers the financial risk of launch and satellite failure from operators to insurers.

ISRO's 16-satellite launch: Who pays when a rocket fails? The growing role of space insurance

Space insurance traces its roots to 1965, when Lloyd’s of London underwrote the first satellite policy for Intelsat I, known as “Early Bird.” Although the mission succeeded and no claim was filed, it set a precedent for insuring space assets.

This particular full Moon gets what astronomers describe as a “triple boost.” Not only is it full and near perigee, but it also occurs when Earth itself is close to the Sun (near perihelion), increasing the amount of sunlight reflecting off the lunar surface.

ISRO’s ‘Bahubali’ set for historic liftoff with India’s heaviest satellite. When to watch

The launch marks a major stride toward India’s self-reliance in building and deploying high-capacity communication satellites. CMS-03 is not only the heaviest communication satellite ever launched from Indian soil but also a symbol of India’s expanding technological and operational confidence in the heavy-lift category.

The LVM3 has completed seven missions with a perfect success rate. It previously launched Chandrayaan-2 and Chandrayaan-3, as well as the crew module for ISRO’s first re-entry test in 2014.
