<![CDATA[ Rocket Lab will launch the first two satellites for Europe's Celeste navigation constellation early Wednesday morning (March 25), and you can watch the action live. ]]>
Satellite navigation systems use satellites to provide autonomous geo-spatial positioning. They allow users to determine their exact location (latitude, longitude, and altitude) anywhere on Earth, at any time, and in any weather conditions.
Space launch vehicles are rockets designed to transport payloads, such as satellites or crewed spacecraft, from Earth's surface into space. They are engineered to overcome Earth's gravitational pull and can vary in size and capability depending on the mission requirements.
