The second engine burn of the Centaur has ended. Next up will be separation of the Lucy spacecraft from Centaur.
Second Centaur Engine Burn Starts
The second engine burn of the Centaur upper stage has begun and will last for about six minutes.
First Centaur Engine Burn Ends, Now in Coast Phase
The first engine burn of the Centaur upper stage has ended. Centaur, with the Lucy spacecraft, is now in a coast phase.
Centaur Takes Over, Payload Fairing Jettisoned
The Centaur upper stage main engine has started its burn following on-time booster engine cutoff and Atlas/Centaur separation. The first of two burns for the Centaur main engine start will last nearly eight minutes. The payload fairing has been jettisoned.
Liftoff! Atlas V Clears the Launch Pad with NASA’s Lucy Spacecraft
We have booster ignition and liftoff of the United Launch Alliance Atlas V rocket at 5:34 a.m. EDT from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida, carrying NASA's Lucy spacecraft! The rocket is on its way, carrying the spacecraft to begin its voyage to explore the Trojan asteroids. About four minutes …
T-4 Minutes and Counting
The NASA launch conductor has polled mission managers for "go" to launch. The Lucy countdown is now underway, proceeding toward a liftoff at 5:34 a.m. EDT. During the last four minutes of the countdown, the Atlas and Centaur propellant tanks will be brought up to flight pressure, the rocket and spacecraft will be confirmed on …
Weather Looks Good for Launch of NASA’s Lucy Spacecraft
A weather update from Will Ulrich, weather officer with the 45th Weather Squadron, reports conditions look good for launch of the Lucy mission.
The Lucy Science Payloads
Lucy will explore the Trojan asteroids with a suite of remote sensing instruments: L'Ralph – an instrument provided by NASA's Goddard Space Flight Center in Greenbelt, Maryland, that consists of two parts: L'Ralph Linear Etalon Imaging Spectral Array (LEISA), an infrared imaging spectrometer that will reveal the absorption lines that serve as the fingerprints for …
The Lucy Mission – First to the Trojan Asteroids
Lucy will explore the Jupiter Trojan asteroids. During its 12-year mission, the spacecraft will explore a record-breaking number of asteroids, flying by one main belt asteroid and seven Trojan asteroids. These small bodies are remnants of our early solar system, now trapped in stable orbits associated with – but not close to – the giant …
