Universe Explorer

Prepare to be part of a momentous event as we launch Northrop Grumman's 19th cargo mission to the International Space Station (ISS). Join us on a journey that combines cutting-edge technology, scientific innovation, and the unrelenting spirit of exploration.

The Solar Dynamics Observatory (SDO) is a NASA mission launched in 2010 to study the Sun's behavior and its impact on Earth's space environment. One of the notable events observed by SDO was the transit of Venus across the face of the Sun in 2012. This event, known as the Venus transit, occurs when Venus passes directly between the Earth and the Sun, appearing as a small, dark dot moving across the Sun's surface.
