When NASA was relevant. I hope one day again.
My bother-in-law worked for JPL on one of the Voyagers in its first years. He later became the team leader on Mars Reconnaissance Orbiter (MRO for short). That vehicle has also gone long over its expected mission life. The information returned from these projects is amazing.
Indeed NASA and JPL can do some truly great scientific work. MRO not only mapped the surfance of Mars in detail, it has gone many seasons and observed the growth and recession of the ice-caps and erosion on the surface. It also has allowed the newer and smaller surface rovers to operate beyond their service lives by compressing and relaying their data that they would otherwise not have the power to transmit.
Make NASA Great Again. MAGA!
