  • Threats to Horseshoe Crabs: Unregulated fishing and damage to eggs by locals.
  • Medicinal Value: Horseshoe crab blood is crucial for development of rapid diagnostic reagents and potential treatment for pre-eclampsia (Note: Pre-eclampsia is a serious pregnancy complication characterized by high blood pressure and damage to organs, most commonly the liver and kidneys).
  • Importance for Human Health: Horseshoe crabs' strong immune system critical for medical research.
  • Warning of Extinction: Scientist who discovered horseshoe crabs warns of their impending disappearance in India.

Recently, researchers at the Indian Institute of Astrophysics (IIA), Bengaluru, developed a low-cost star sensor called Starberry-Sense.

  • The Starberry-Sense is based on commercial/off-the-shelf components and is powered by a Raspberry Pi, a small, single-board Linux computer, making it affordable and accessible.
  • It can help small CubeSat (cube-shaped satellite)class satellite missions to find their orientation in space.
  • The team coupled highly optimized algorithms with Raspberry Pi to create a potent star sensor.
  • Starberry-Sense has successfully undergone vibration and thermal vacuum tests, qualifying it for space launch and operations.
  • The sensor's success can lead to cost-effective solutions for small satellite missions in the future, revolutionizing space exploration.

Raspberry Pi is widely used in hobbyist and educational projects, as well as in professional applications. It was developed by the Raspberry Pi Foundation in the UK and is designed to be affordable and accessible.
