What a uniquely impressive asset our @B2Science is! Had a fantastic tour with John Adams, Ron Wood, and @moonyguy, who explained the research conducted by our faculty, staff and students in Earth system sciences, agrivoltaics, space situational awareness, and so much more.

Peregrine lander at 388,000 km from Tucson on Jan. 12, 2024. Object is Visual Magnitude ~18.5. Also got a shot of the Vulcan Centaur heading out to heliocentric space at a distance of 1.085 million km (second video).
Peregrine lander from our telescope in Tucson tonight. The object was 103500 miles from the Earth when we took the pictures. The lander is the small white dot in the middle. The telescope tracked on the lander's motion so stars appear as white dashes.

#Asteroid 2022 YG shows signs of being a quasi-satellite of Earth. @AdrienCoffinet pointed out this relationship now that we have a year's worth of data. It has been in quasi state since 1961 and will remain so until 2181. Kamoʻoalewa is another example of a quasi-satellite.

Chandrayaan-3 Mission:
Ch-3's Propulsion Module (PM) takes a successful detour!
In another unique experiment, the PM is brought from Lunar orbit to Earth’s orbit.
An orbit-raising maneuver and a Trans-Earth injection maneuver placed PM in an Earth-bound orbit.

We're still obsessed with asteroids over here. 😉
@NASA’s Lucy spacecraft will fly by its first asteroid this week. To prepare, researchers used data previously collected by the WISE mission (now NEOWISE) to better understand what Lucy might encounter. go.nasa.gov/3QaUBFi

The large brown rocky asteroid is centered in the image with the spacecraft approaching it form the right side. The spacecraft has a silver metal body with two large, orange octagon-shaped solar arrays protruding from the top and bottom.

The backdrop is filled with blue-green dots of stars and bright red spots representing planets. A blue-green haze creeps in from the lower left corner and upper right, representing light emitted predominantly from stars and galaxies.

At 3:42 a.m. MST on September 24, @UArizona researchers began tracking the path of the OSIRIS-REx sample return capsule as it hurtled toward Earth.
The data collected will help test algorithms used to pinpoint asteroids that could impact Earth.
