S03E160: India's Space Projects, Starship's Next Step, and Moon's Hidden Water

Astronomy Daily - The Podcast

Astronomy Daily - The Podcast: 21st September 2024
Welcome to Astronomy Daily, your go-to source for the latest space and Astronomy news. I'm your host, Anna, and today we have an episode packed with groundbreaking stories. From India's ambitious new space projects and SpaceX's plans to catch Starship, to exciting discoveries about water on the moon, groundbreaking observations from a new X-ray telescope, and concerns about satellite interference with radio Astronomy. Let's dive right in!
Highlights:
- India's Space Ambitions: India has greenlit an ambitious slate of space projects, allocating a substantial $2.7 billion to push the boundaries of its space capabilities. At the forefront is the Chandrayaan IV mission, a bold lunar sample return effort targeting the moon's south pole. Equally exciting is the Shukrayan mission, India's first Venus orbiter, now targeted for 2028. Perhaps most ambitious is the Bharatiya Antariksh Station (BAS), India's first space station module, slated for launch by the end of 2028 with full operational status expected by 2035. These projects highlight India's growing expertise and determination to become a key player in the global space arena.
- SpaceX's Starship Catching Plans: SpaceX is gearing up for another groundbreaking achievement with its upcoming Starship test flight. The company plans to catch the massive Super Heavy first stage booster using the chopstick arms of the launch tower at their Starbase facility in Texas. This ambitious maneuver, if successful, would take rocket reusability to the next level, dramatically reducing turnaround time between flights. Regulatory reviews have delayed the launch, but the FAA is expected to complete its assessment by late November.
- Chinese Reusable Rocket Technology: Chinese private space companies, Deep Blue Aerospace and Landspace, are making significant strides in developing reusable rocket technology. Both firms have conducted impressive high-altitude hop tests with their prototype vehicles, aiming to develop fully reusable orbital launchers. These tests represent significant progress for China's commercial space sector, working towards cost-effective reusable launch capabilities.
- Abundant Water on the Moon: New research reveals that water is far more abundant on the moon than previously thought. Data from NASA's Moon Mineralogy Mapper shows that water and hydroxyl molecules are widespread across the lunar surface, not just confined to the poles. This discovery opens up possibilities for more flexible mission planning and could reduce the need to transport water from Earth, making long-term lunar missions more sustainable.
- XRISM's Groundbreaking Observations: Japan's X-ray Imaging and Spectroscopy Mission (XRISM) has unveiled its first results, capturing stunning observations of a supermassive black hole in galaxy NGC 4151 and a supernova remnant in the Large Magellanic Cloud. These observations are revolutionizing our understanding of the X-ray universe, with over 3000 proposals submitted for future studies.
- Satellite Interference with Radio Astronomy: New research reveals that SpaceX's second-generation V2 mini Starlink satellites are emitting up to 32 times more radio waves than their predecessors, posing a significant threat to radio Astronomy. This underscores the urgent need for dialogue between the Astronomy community and satellite companies to find solutions that allow both Internet access and scientific research to coexist.
