ISEE accomplished its mission long ago. Adding complexity to improve the odds of amateurs resurrecting it 20 years later at the risk of increased cost and chance of malfunction doesn't seem like ...

Before the group can fire the thrusters on ISEE-3 to change its course, they need to define its present orbit as accurately as possible. The plan is to use NASA's DSN for ranging. The group wasn't ...

It is much too small and moving too fast past the Earth to be picked up by a telescope. It is about 2 meters wide, and passed by at 300,000 km at the closest point. That makes it around 0.0014 arc ...

ISEE-3 was originally a NASA spacecraft launched in the 1970s, but since then it's been the subject of the first-ever public crowdfunding campaign to provide it a budget when normal funding was ...

ISEE 3 is a spacecraft from the 1970s currently creeping back up on Earth orbit. NASA abandoned it, but after a crowdfunding campaign, a team of citizen-scientists visited Arecibo with homebrew ...

There’s still a lot of work to be done by the ISEE-3 team as they figure out how best to capture the spacecraft and prepare for the burn in the following week. They should have the exact orbit ...

The International Sun-Earth Explorer 3, or ISEE-3, could get a new lease on life in August, when a team of volunteers and aerospace engineers—constituting the ISEE-3 Reboot Project—attempt to ...

It spoke a lost language. Next month, ISEE-3 will finally come home, its first visit in 30 years (its slightly faster orbit means it has done 31 laps of the Sun in the same time Earth has done 30).
