Mississippi State researcher to play vital role in NASA artificial star mission – SuperTalk Mississippi


A Mississippi State University astrophysicist will lead a $19.5 million NASA space mission to put an artificial star in orbit around the Earth.

Angelle Tanner, an associate professor in the Department of Physics and Astronomy at Mississippi State, is serving as the principal investigator on the Landolt mission, part of the NASA Astrophysics Pioneers program. The program’s artificial star will allow scientists to calibrate telescopes and more accurately measure the brightness of stars ranging from those nearby to the distant explosions of supernovas in far-off galaxies.

By establishing absolute flux calibration, the mission will address several open challenges in astrophysics including the speed and acceleration of the universe expansion.

Tanner is managing a sub-grant of $300,000 for the project. Her work on the mission relies on cubesats, which are small satellites orbiting Earth. Each cubesat contains four lasers specially calibrated by the National Institute of Standards and Technology, an agency of the U.S. Department of Commerce.

“The program includes a cubesat and a set of ‘ground stations,’ which are telescopes. As the cubesat flies over a location, the ground stations will observe the cubesat in the same frame as their science target,” Tanner said.

“The point is to use the image of the laser to determine the amount of starlight being absorbed by the Earth’s atmosphere. This will reduce the uncertainties in the value of the brightness of the star from 10 percent to one percent. That makes a difference when propagated into the properties of exoplanets and, believe it or not, some of the parameters used to determine the structure of the universe.”

Working with the team at George Mason University in Virginia, the mission is named in honor of LSU Professor Arlo Landolt, who Tanner calls the “the father of photometry.” To follow the mission’s progress, click here.

Thompson defeats Turnage to highlight U.S. House primaries in Mississippi – SuperTalk Mississippi

Thompson defeats Turnage to highlight U.S. House primaries in Mississippi – SuperTalk Mississippi


Political newcomer and Capitol Hill attorney Evan Turnage proved no match for longtime U.S. Rep. Bennie Thompson, who defeated him and one other challenger to earn the Democratic nomination for Mississippi’s 2nd Congressional District on Tuesday.

Some politicos thought Turnage – who went to Yale and later worked for some of Thompson’s Democratic colleagues, including Senate Minority Leader Chuck Schumer (D-N.Y.) – wouldn’t necessarily win but could make waves as one of the more viable candidates to challenge Thompson in recent years. However, that wasn’t the case as Thompson garnered approximately 85% of the vote when the race was called.

Thompson, 78, is seeking an 18th term. The civil rights leader who chaired the Jan. 6 Committee was first elected in 1993 and serves as a ranking member on the House Homeland Security Committee. He will face either Ron Eller or Kevin Wilson on the Republican side, a race yet to be called as of late Tuesday night, and independent Bennie Foster in November’s general.

All of Mississippi’s U.S. House seats are up for grabs this year.

In the 1st Congressional District, Republican Rep. Trent Kelly ran unopposed, while civil rights attorney and University of Mississippi School of Law professor Cliff Johnson beat former state lawmaker Kelvin Buck in the Democratic primary. Libertarian challenger Johnny Baucom awaits Kelly and Johnson in the general.

In the 3rd Congressional District, both Republican Rep. Michael Guest and Democrat Michael Chiaradio ran unopposed. They will meet Libertarian Erik Kiehle in the general.

In the 4th Congressional District, Republican Rep. Mike Ezell had over 80% of the vote when his race was called against former Mississippi Department of Marine Resources officer and political staffer Sawyer Walters. State Rep. Jeffrey Hulum easily won the Democratic nomination over Paul Blackman and D. Ryan Grover. Ezell and Hulum will face independent Carl Boyanton in the general.

Arguably the most watched races of the night occurred in the state’s lone U.S. Senate seat in this year’s cycle. Republican Sen. Cindy Hyde-Smith had no problem with Ocean Springs doctor Sarah Adlakha, seeing her name bolded around 30 minutes after the polls closed. It wasn’t long after that when Lowndes County District Attorney Scott Colom was announced the winner of the Democratic primary over Priscilla Till and Albert Littell. Independent Ty Pinkins will meet Hyde-Smith and Colom in the general on Nov. 3.
