Vishnu Reddy

At the #ISOS Summit, presented in partnership with @AZCommerce & sponsored by @UArizona, hear Vishnu Reddy, Director of the @UArizona Space Safety, Security & Sustainability Center, on the future of #space exploration & competition. 3/26 | 2–5 PM | RSVP: app.glueup.com/event/internat…

As space between Earth and the Moon grows more crowded, the U of A is helping lead the way in lunar traffic control. Join Dr. Tomás Díaz de la Rubia and Dr. Vishnu Reddy for a conversation on managing cosmic clutter and securing the future of cislunar operations. events.trellis.arizona.edu/en/f44lNu67/tr…

Months after earning his Ph.D., Adam Battle received a $1M grant from NASA. In partnership with his mentor, Vishnu Reddy, they will continue characterizing near-earth asteroids for the next four years. Learn how @uazresearch supported their work from the early stages research.arizona.edu/news/million-d…

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.

There it is! The total solar eclipse captured by our Space4 Center team, led by Lunar and Planetary Laboratory professor Vishnu Reddy and designated campus colleague Dr. Lucille Le Corre. They are working under the path of totality in Fredericksburg, Texas today #solareclipse2024

@tony873004 @Unistellar @AllPlanets Booster is V~12 to 15 (tumbling) and the spacecraft is V~15. They are 15 arc seconds apart from each other.

@Unistellar @AllPlanets This is probably the booster, as the actual lander should be much dimmer. The dotted path probably means it is tumbling, which the spent booster is expected to do.

@Int_Machines Nova-C lander (fainter moving dot to the right) and the Falcon-9 booster (bright moving dot to the left) from our backyard telescope in #Tucson tonight. The objects were 175400 miles from the Earth when we took the pictures.

Our proposal about how wet is the Moon will be funded. Congratulations team- Pranabendu Moitra, Sabrina Schwinger, @deep_magma, @bosonicpowers, Rick Hervig, @jessrocks88, Vishnu Reddy and yours truly! #NASAfunded @uazgeos

Vulcan Centaur

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).

@JustinScerini No luck. Looks like ULA did a large enough burn that the booster is pretty far from the spacecraft. So it is not in the same field of view as the Peregrine.

@moonyguy Any luck of getting a chance to view tonight?

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.

@david_dbriggs V Mag 16.5 last night. I could see it in 100 second stacked images 10 x 10 sec images.

@tony873004 Nope. Nothing within a degree that I could see. Too cold out tonight in Tucson to search around. Maybe tomorrow night.

@moonyguy Any luck finding the Centaur? It might be just a few FOVs away, and a magnitude brighter.

@moonyguy @astromarkmarley What's Peregrine's trajectory relative to Earth and Moon?

NEWS: This spring semester, @uarizonalaw will offer a course on the law of space for the first time. The course will be co-taught by @UArizonaLPL Professor Vishnu Reddy (@moonyguy) and @uarizonalaw Professor @andrewkwoods. Learn more ▶️ bit.ly/3NP5EUt

#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. isro.gov.in/Ch3_Propulsion…
