Nasa gives up on trying to save doomed space telescope

• Nasa has abandoned efforts to save the Swift Observatory space telescope, which will now burn up in Earth's atmosphere no earlier than October.
• The telescope had been sinking from its orbit faster than expected due to intense solar activity after more than 20 years of cosmic observations.
• A $30 million rescue mission by startup Katalyst Space Technologies failed after its Link spacecraft suffered persistent control and positioning problems.
• Katalyst will keep operating Link near Swift to demonstrate capabilities for potential future rescue missions.
• The setback leaves the future of the Hubble Space Telescope uncertain, as it is also losing altitude and was next in line for a rescue attempt.
