S03E156: Ariane 6's Comeback, Starving Galaxies, and Mars' Hidden Secrets

Astronomy Daily - The Podcast

Astronomy Daily - The Podcast: 17th September 2024
Welcome to Astronomy Daily, your go-to Podcast for the latest and most exciting developments in space and Astronomy. I'm your host, Anna, and I'm thrilled to bring you another episode packed with fascinating stories from the cosmos. Today, we've got a stellar lineup of topics that span from Earth to the far reaches of our galaxy. So strap in and prepare for liftoff as we journey through the universe's latest mysteries and marvels.
Highlights:
- Ariane 6 Rocket Update: Europe's newest rocket, the Ariane 6, made its inaugural launch on July 9th this year. Despite a successful series of trials, the mission ended with the upper stage coasting in orbit, unable to complete its final planned maneuver. ArianeSpace has traced this issue to a fixable software fault and is committed to staging a second mission before the end of the year. This rocket, developed at an estimated cost of €4 billion, aims to maintain Europe's competitiveness in the global launch market.
- James Webb Space Telescope Discovery: The James Webb Space Telescope has identified a supermassive black hole that's starving its host galaxy, nicknamed Pablo's galaxy. Located 12 billion light-years away, this galaxy is in a quenched state, expelling gas at speeds of about 1000 km/second, effectively cutting off the galaxy's fuel for star formation. This discovery is a crucial piece of evidence in understanding how galaxies evolve over cosmic time.
- US-Australia Spaceport Collaboration: The recent ratification of the US-Australia Technology Safeguards Agreement (TSA) opens up new possibilities for US companies to use Australian spaceports for launches and payload returns. Australia's vast uninhabited landscapes and less congested air and sea traffic offer unique advantages for launch and reentry. This collaboration could further strengthen strategic capabilities between the two nations.
- New Mars Revelations: Recent gravity data studies have uncovered dense, large-scale features beneath Mars' surface, shedding light on the planet's geological history and volcanic activity. These findings suggest that Mars might still have active internal movements. Scientists are proposing the Martian Quantum Gravity (MaQis) mission to map Mars' gravity field in unprecedented detail.
- This Week's Rocket Launches: SpaceX is gearing up for two Falcon 9 missions this week. The first launch from Cape Canaveral will carry a pair of Galileo global positioning satellites, while the second from Vandenberg Space Force Base will launch another batch of Starlink satellites, pushing the number of operational Starlink satellites past the 6000 mark. Rocket Lab is also preparing for an Electron launch from New Zealand, carrying the second batch of nanosatellites for Kinéis.
