European Space Agency Considers Redesigning X-ray Space Telescope – Nation World News


Lack of partners prompted the European Space Agency to redesign the Athens Telescope

Nation World News, France – The European Space Agency (ESA) is looking at ways to redesign its main X-ray space telescope after several ESA member states withdrew from the project. The Athena or Advanced Telescope for High-Energy Astrophysics was selected by ESA in 2014 and was intended to be launched at the Sun–Earth Lagrangian point 2, about 1 million miles (1.5 million miles) from Earth on the night side of the planet. kilometer) away.

There, he will study supermassive black holes, galaxy cluster formation, supernovae and other cosmic phenomena by observing X-ray emissions. space news The report ESA is now exploring the possibility of reducing observatory design in the face of rising costs. This caption cites observations by ESA’s astronomy and astrophysics coordinator Paul McNamara during a July 21 presentation to the US Space Agency’s (NASA) Astrophysics and Astronomy Committee.

informed of space As of Tuesday (9/8/2022), the estimated cost of Athens was approximately EUR 1.17 billion, adjusted for today’s prices, when it was first voted on. But by May this year, according to the report, the forecast had risen to 1.9 billion euros.

The mission has made good progress in technology, including the development of a new light mirror. However, ESA fees have increased as many partners have withdrawn. “Some member states have concluded that they cannot fulfill their commitments,” said McNamara, who called on ESA to assume its responsibilities.

ESA wants the cost increase to have no impact on other missions and now wants to re-cover or rescope Athens to reduce prices. McNamara said the agency did not want to cancel the project.

The revised design, known as NeuAthena, will likely change the configuration of the project’s science instruments and mission science objectives. The mission was originally slated to launch in 2028, but changes to the mission could have implications for its schedule.

The changes could also affect NASA, which is involved in science payloads, providing test and calibration hardware and facilities. McNamara suggested that ESA would be open to a more in-depth engagement with the space agency as an option rescope,

“Nothing is covered. We are looking for whatever effort we can to achieve the best possible mission within the constraints of the program,” he said.
