Eclipse

Satellites that cycle into eclipse must carry sufficient battery capacity to maintain AI inference workloads through shadow periods, which shifts design optimization toward energy storage.

Geostationary Orbit (GEO) has zero atmospheric drag and near-continuous sunlight interrupted only by seasonal eclipse periods.

Proba-3 was launched in December 2024 and achieved the first precise formation flight in space and the first artificial solar eclipse in orbit.

Proba-3 is designed to create a total solar eclipse on demand by flying its two spacecraft in a controlled formation.

Proba-3 can create its artificial eclipse once every 19 hours and 40 minutes, lasting up to 6 hours, while natural total solar eclipses occur once or twice a year and last only a few minutes.

The volume of data from Proba-3 is equivalent to about 6000 total eclipse campaigns on Earth.

The team compared the total flux before and during secondary eclipse to infer the temperature of TOI-561 b's dayside hemisphere.

Eclipse is equivalent in size to CZ-12B.

Work for the ECLIPSE project will be carried out at Lodestar's London headquarters using its in-house In-Orbit Servicing, Assembly and Manufacturing testbed.

The ECLIPSE project focuses on advancing Mithril's LiDAR sensing technology to provide high-precision depth perception.

Eclipse led the Series E funding round for Ursa Major, joined by Woodline Partners, Principia Growth, XN, and Alsop Louie Partners.

Eclipse mapping measures the minute changes in light as an exoplanet passes behind its star, creating a color-coded temperature map with latitude, longitude, and altitude.

Firefly is making progress on the Eclipse program.

CCOR-2 uses a single external occulter to block direct sunlight and create an artificial eclipse for high-contrast imaging of the solar corona.

Firefly captured the first high-definition images of a solar eclipse and sunset from the Moon’s surface.

The lander captured temperature data ranging from 230 degrees Fahrenheit at the hottest part of the lunar day to -275 degrees Fahrenheit during the solar eclipse’s totality.

Firefly's team captured first-of-its-kind data during phenomena on the Moon’s surface, including sunrise, sunset, and a solar eclipse.
