The MESSENGER spacecraft successfully completed its first orbit-correction maneuver on June 15 to reset its periapsis altitude â€” the lowest point of MESSENGERâ€™s orbit about Mercury relative to the planetâ€™s surface â€” from 506 kilometers to approximately 200 kilometers.
The Johns Hopkins University Applied Physics Laboratory is sending a spacecraft closer to the sun than any probe has ever gone â€“ and what it finds could revolutionize what we know about our star and the solar wind that influences everything in our solar system.
The MESSENGER spacecraft delivered a critical deep-space maneuver today â€“ 64 million miles (103 million kilometers) from Earth â€“ successfully firing its large bi-propellant engine to change the probeâ€™s trajectory and target it for its second flyby of Mercury on October 6, 2008.
