InSight and Juno keep on trucking

Where it stands: Juno's mission has been extended to September 2025 or whenever its life ends with a crash into Jupiter's atmosphere.

• InSight will continue its mission to study Mars' geology and seismic activity from the Martian surface through December 2022.

What's next: Both missions are expected to make good use of their extended time at Jupiter and Mars.

• InSight's extra two years will see the spacecraft collect more data on marsquakes to help create a long-term dataset that scientists can refer to for years to come, according to NASA.
• Juno will broaden the scope of its studies to observe Jupiter's rings and moons including flybys of Ganymede, Europa and Io.

The big picture: NASA often extends the missions of its satellites and spacecraft in space if they're functioning well and still beaming home useful data.

• The Mars Opportunity rover, for example, landed on Mars in 2004 for a 90-day mission, but the little spacecraft managed to keep roaming the Red Planet for nearly 15 years, after being granted multiple extended missions.
