NASA's Lucy asteroid probe will watch the Super Flower Blood Moon eclipse from deep space

Like a flashlight beam penetrating the dark, the moon's reflected sunlight will blink on and off during a lunar eclipse just visible by an asteroid-bound spacecraft.

A NASA spacecraft called Lucy plans to take a side view of the Super Flower Blood Mmoon lunar eclipse of May 15 on its way to visit clusters of asteroids that orbit the sun at about the same distance as Jupiter, called Trojans. The spacecraft, which launched in October 2021, is on a path back to Earth for a gravity assist to the outer solar system in October, but right now the spacecraft is still far away: roughly 70% of the distance between Earth and the sun. You can watch the Flower Blood Moon eclipse in webcasts, starting at 9:30 p.m. EDT (0130 GMT).

Regardless, at least some of the high-definition cameras on the spacecraft should (in theory) be able to see the moon passing into the Earth's shadow in the lunar eclipse on May 15 and 16, according to officials with the Southwest Research Institute in Colorado, where the mission's main science team is based.

"From this distance, Lucy will view the eclipse from an angle rarely seen," officials stated in a press release (opens in new tab) Thursday (May 12). "To Lucy, the gibbous Earth and moon will be easily visible. As the moon enters the shadow of the Earth it will blink out, [and] no longer be visible, until it moves again out of the Earth's shadow."

Top telescope pick!

To see the eclipse in action, Lucy will perform imaging using its L'LORRI (Lucy Long Range Reconnaissance Imager) high resolution panchromatic camera. That's a next-generation instrument based on a version that flew on the New Horizons spacecraft that whizzed by Pluto and is visiting other asteroids in the faraway Kuiper Belt.

The press release hinted that other imagers may be involved, but did not offer specifics. Lucy carries a few other such instruments. There's L'Ralph, a "two in one" instrument with a color camera (the Multispectral Visible Imaging Camera, MVIC) and infrared imaging spectrometer (Linear Etalon Imaging Spectral Array, LEISA).

Additionally, during Lucy's main mission, the Terminal Tracking Cameras (T2CAM) provide wide-field imaging and L'TES, the infrared Thermal Emission Spectrometer, will measure the surface temperature of target asteroids

"Viewing this eclipse will allow the Lucy team to do a 'test run' of the observation procedures, making sure that all the imagers and equipment are working as expected," SwRI stated. "It is also a fun opportunity as it is extremely rare to get real images of astronomical events like this, from such a unique vantage point."

On Earth, the Flower Moon's eclipse will be visible in total phase from portions of the Americas, Antarctica, Europe, Africa and the east Pacific. A penumbral eclipse (where the edge of Earth's shadow will fall over the moon) is visible in New Zealand, eastern Europe and the Middle East, although this type of eclipse is difficult to observe.

While timing depends on your location, TimeandDate.com (opens in new tab) says the partial eclipse phase of the moon eclipse begins May 15 at 10:28 p.m. EDT (0228 GMT on May 16). It will get to the red-hued Blood Moon peak May 16 at 12:11 a.m. EDT (0411 GMT). Then the event ends at 1:55 a.m. EDT (0555 GMT). Note the penumbral eclipse will begin about an hour earlier and end about an hour after the partial eclipse.
