The European Space Agency (ESA) is contemplating methods to revamp a serious X-ray space telescope after a lot of ESA member states have backed out of the mission.
Athena, or Advanced Telescope for High-Energy Astrophysics, was chosen by ESA in 2014 and is meant to launch to Sun-Earth Lagrangian level 2, a spot about 1 million miles (1.5 million kilometers) away from Earth on the planet’s evening aspect. There, it might examine supermassive black holes, formation of galaxy teams, supernovas and different cosmic phenomena by observing X-ray emissions.
However, ESA is now potentialities to cut back the design of the observatory within the face of rising prices, SpaceNews reported (opens in new tab), quoting feedback from Paul McNamara, ESA astronomy and astrophysics coordinator, throughout a July 21 presentation to NASA’s astronomy and astrophysics committee.

Athena had an estimated value of about 1.17 billion euros, adjusted to at present’s costs, when first chosen. However, by May of this 12 months, estimates had grown to 1.9 billion euros, in accordance with the report.
The mission has been progressing effectively on the expertise aspect, together with the event of a brand new, light-weight mirror. However, ESA’s prices have risen attributable to a lot of companions pulling out. “Several of the member states concluded that they were unable to fulfill their commitments,” McNamara stated, asking that ESA take over their accountability, in accordance with the report.
ESA is eager that the elevated prices don’t affect different missions and is now seeking to “rescope” Athena to scale back its pricetag. McNamara acknowledged that the company is just not seeking to cancel the mission.
The revised design, often called NewAthena, will seemingly change the mission’s science instrument configuration and the mission’s science objectives. The mission was initially slated to launch in 2028, however the modifications to the mission may have implications for its schedule.
The modifications may even have repercussions for NASA, which is concerned in science payloads, offering {hardware} and testing and calibration amenities. McNamara recommended that ESA can be open to extra intensive involvement from the space company as one “rescope” possibility.
“No door is closed,” he stated. “We’re looking for any way we can try to get the best mission possible within the programmatic constraints.”
