Lucy

The first engine burn of the Centaur upper stage has ended. Centaur, with the Lucy spacecraft, is now in a coast phase.

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.

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 …

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 …

A weather update from Will Ulrich, weather officer with the 45th Weather Squadron, reports conditions look good for launch of the Lucy mission.

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 …

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 …

Good morning, and welcome to launch day for NASA's Lucy spacecraft. The first space mission to explore a diverse population of small bodies known as the Jupiter Trojan asteroids will launch on a United Launch Alliance Atlas V 401 rocket from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Launch is targeted …

The rocket standing ready on the pad with NASA's Lucy spacecraft at Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida, is a United Launch Alliance Atlas V 401 configuration. It is the workhorse of the Atlas V fleet, delivering about half of all Atlas V missions to date. The 401 designation …

Launch of the United Launch Alliance Atlas V 401 rocket with NASA's Lucy spacecraft is on track for Oct. 16, 2021 at 5:34 a.m. EDT, from Space Launch Complex 41 at Cape Canaveral Space Force Station in Florida. NASA's Launch Services Program, based at Kennedy Space Center, America's premier multi-user spaceport, is managing the launch. …
