Multi-million dollar rescue mission launched to save aging space telescope
It's a classic scenario: an aging space telescope, having been in orbit for over 20 years and having detected some of the universe's most powerful explosions, is on the brink of falling from space. Many might think it's time to let the old satellite rest. However, the cost of a rescue mission to save this particular space telescope is estimated at $30 million. Is it worth it?
Why save the falling telescope?
The answer, in short, is yes. This space telescope, known as the Swift Observatory, is far from obsolete. Launched in 2004 for a planned two-year mission, Swift has surpassed expectations, functioning effectively for over two decades as an orbital sentinel. The telescope is constantly on standby, ready to detect and study gamma-ray bursts, the most powerful explosions in space. Neither the famous Hubble Space Telescope nor the James Webb Space Telescope can perform this particular task. Therefore, a rescue mission is being planned to save the Swift.
The satellite is expected to fall out of its orbit by the end of the year due to higher-than-expected drag from Earth's outer atmosphere, caused by solar storms. To prevent this, a company known as Katalyst Space is leading the rescue mission using its new Link spacecraft.
"We didn't want to create the assumption that every satellite that falls out of orbit must be saved," explains the director of the Astrophysics Division. "But this isn't just any satellite. It's a swift observatory that can quickly scan the night sky to find things that go boom in the night."
Swift's unique capabilities
Built and launched in 2004 for $250 million, Swift has served as a sort of first responder, promptly spotting far-off gamma-ray bursts. These bursts are fleeting, lasting just seconds, but release more energy than our sun will in its entire lifetime. Swift's success has led to several mission extensions.
"Swift is named for its ability to rapidly and autonomously repoint its X-ray and UV telescopes almost anywhere on the sky," explains the Swift Principal Investigator. "The universe is a very dynamic place. A massive star explodes somewhere in the cosmos every second."
The Hubble Space Telescope can take clearer pictures than Swift, but it takes up to two days to point Hubble at a new target. Swift, on the other hand, can do this in just a few minutes. It's the first responder of space, facilitating the tackling of questions that would be impossible for any single facility to answer.
Swift's contributions to science
Swift's observations have helped confirm that the heaviest elements in our universe, including precious metals like platinum and gold, were created by the explosive power associated with gamma-ray bursts. In 2022, Swift discovered a gamma-ray burst so bright that scientists named it the "BOAT," or Brightest of All Time. At that time, it was the most powerful space explosion ever observed.
The Swift Boost rescue mission
To save Swift, the untested company Katalyst Space has been engaged to launch the Swift Boost mission. This involves constructing a brand-new spacecraft in an incredibly short period of time, then launching it for a rendezvous with Swift. The goal is to push the Swift telescope to a higher orbit that would ensure at least five more years of scientific life if successful.
The mission is a huge gamble and something that's never been attempted before. The top scientist working on Swift admits he has had many sleepless nights, but working with the team gives him great confidence.
What's at risk?
If Katalyst is successful in saving Swift, it will have achieved something unprecedented in space history. The company already has a contract with the U.S. Space Force to demonstrate a similar capability for larger spacecraft using its new Nexus vehicle.
If the mission fails, Swift will fall from space, a fate it was already destined for. But the Swift science team is optimistic. They've even put Swift in a low-power mode to slow its descent.
"The risk here is relatively low," says the Swift Principal Investigator. "The potential benefit of many more years of science makes this a no-brainer."
