What Research Is Conducted at Goldstone Observatory?
Goldstone Observatory, part of NASA's Deep Space Network (DSN), is a key facility located in the Mojave Desert, California. This observatory is crucial for a range of scientific and exploratory missions that expand our understanding of the universe. With its large antenna dishes, Goldstone plays a pivotal role in communicating with space missions, tracking, and collecting data from distant spacecraft. Here we explore the diverse research activities undertaken at this facility.
Deep Space Communication
One of Goldstone's primary functions is to facilitate deep space communication. Equipped with several high-gain antenna dishes that include the impressive 70-meter (230 feet) DSS-14 antenna, Goldstone is capable of receiving and transmitting signals to and from spacecraft located beyond the moon.
Key Capabilities:
- Long-Distance Communication: Enables reliable communication with missions across the solar system, from Mars rovers to Voyager probes at the edge of our solar system.
- Data Relay: Transmits scientific data collected by spacecraft back to Earth, including high-resolution images, atmospheric data, and more.
Radar Astronomy
Goldstone Observatory is also renowned for its contributions to radar astronomy. Using high-power radar systems, researchers at Goldstone can study nearby asteroids, comets, and other celestial bodies. This research is critical for understanding the composition, trajectory, and characteristics of objects that come close to Earth.
Scientific Contributions:
- Near-Earth Object Tracking: Helps in assessing the threat posed by asteroids and comets by determining their size, shape, and orbit.
- Planetary Science: Provides detailed radar images of the Moon, Mars, and other planets, contributing to geological and atmospheric studies.
