NASA has launched a new mission, Pandora, to get the most out of its James Webb Space Telescope. The $20 million mission aims to help scientists understand how they can study exoplanets using Webb.
Pandora is a small satellite that will observe 20 preselected exoplanets and their stars simultaneously, allowing astronomers to correct their measurements of the planet's atmospheric composition and structure based on the ever-changing conditions of the host star. This will capture short-term and longer-term changes in each star's behavior.
The mission is part of NASA's Astrophysics Pioneers program, an initiative that aims to solicit ideas for lower-cost astronomy missions. Pandora was developed by Blue Canyon Technologies, a Colorado company, and uses a small satellite platform that had technology on the shelf from a national security program.
Pandora will help James Webb data be even more precise by providing context and understanding for these host stars and planetary systems. The mission's findings could extend to other worlds in our galactic neighborhood, with over 6,000 exoplanets already confirmed.
The Pandora spacecraft weighed approximately 716 pounds (325 kilograms) at launch and was launched on a SpaceX Falcon 9 rocket. Scientists hope they can extend the lessons learned from Pandora's observations of a sample of 20 exoplanets to other worlds in our galactic neighborhood.
"The problem became apparent in the 2010s as astronomers used more powerful telescopes to see the finer details of exoplanets," said Daniel Apai, a member of Pandora's science team. "We always suspected that stars are not perfect. At some point, it becomes a problem. But it was not recognized how serious a problem that is until about 2017 or 2018."
The mission has the potential to break down one of the biggest scientific barriers to unlocking the secrets of exoplanets. With Pandora's small telescope, scientists can assess the quality of their data and make sure they are detecting real signals from exoplanets.
"It's been very, very challenging to try and squeeze this big amount of science into this small cost box, but that's kind of what makes it fun, right?" said Tom Barclay, deputy project scientist and technical lead on the Pandora mission. "We have to be pretty ruthless in making sure that we only fund the things we need to fund. We accept risk where we need to accept the risk, and at times we need to accept that we may need to give up performance in order to make sure that we hit the schedule and we hit the launch schedule."
The Pandora mission is an example of how advances in small satellite technology are enabling lower-cost astronomy missions. Companies like Rocket Lab and SpaceX are pushing the boundaries of what can be achieved with smaller spacecraft, and NASA is taking advantage of these advancements to get more science done.
"For astrophysicists, this capability is amazing because science is moving fast," said Apai. "Exoplanet science is changing. I would say every three or four years, we have breakthroughs. And the product keeps changing. We push the boundaries, and if you ever have to work with 20- or 25-year-long mission lifetimes, that really just limits progress."
