NASA Approves Landolt Space Mission: First Artificial Star to Aid Astronomical Understanding

NASA has recently announced the Landolt Space Mission, scheduled to launch in 2029, which aims to place the first artificial star into Earth's orbit. This project was approved in February, and announced to the public on June 10. With a budget of $19.5 million, the mission will involve a team of 30 individuals.

The artificial star, resembling a shoebox-sized satellite, will be equipped with eight lasers. Its primary function is to replicate various types of stars and supernovae found in the universe by directing lasers towards ground-based telescopes.

This groundbreaking technology will significantly contribute to astronomers' understanding of authentic cosmic objects. Once deployed, the artificial star will facilitate the fine-tuning of telescopes, enabling experts to more accurately measure stellar brightness.

In addition to its role in advancing astronomical knowledge, the Landolt Space Mission aims to address challenges in astrophysics through absolute flux calibration. This calibration process seeks to tackle complex issues such as determining the speed and acceleration of the universe's expansion. Currently, accurately measuring the rate at which stars emit photons, a crucial parameter in this calibration, presents significant difficulties.
