A pair of on-going NASA missions — the Juno space vehicle in orbit around Jupiter and the InSight lander on Mars — have been extended comply an international review .
An main review panel pronounce both Juno and InSight have “ produced surpassing science , ” and that both missions should be countenance to continue , accordingto a NASA command .
“ The Senior Review has validated that these two planetary scientific discipline mission are probable to continue to bring new discoveries , and produce new question about our solar system , ” Lori Glaze , conductor of NASA ’s planetary science division , aver in the statement .

The decisiveness must ’ve been a no - brainer , as the Juno and InSight delegation have been quite successful , and both extend to gather valuable scientific data . What ’s more , extending these deputation is a heck of a lot garish than get to develop new missions . And as NASA pointed out , “ extensions let foreign mission to continue to acquire valuable long - duration datasets . ”
Juno come at Jupiter in July 2016 where it has been working for the retiring four - and - a - half age . The spacecraft was place in a extremely elliptical orbit that take it far away from Jupiter , but during its perijove ( closest access ) it comes to within 2,600 mile ( 4,184 kilometers ) of the gas giant ’s cloud tops . Juno will make four perijoves in 2021 , the first on Feb. 21 .
Juno has taken some of the mostgorgeous photosever of Jupiter , and has made important contributions to our understanding of the planet ’s atm , interior structure ( includingshallow lightning and mushy hail ) , and magnetosphere .

With the extension , Juno will be in job until 2025 — assuming it does n’t drop dead first — during which sentence it will search Jupiter ’s rings ( yes , Jupiter has band ) and several declamatory moons , namely Io , Ganymede , and Europa , the latter of which couldharborbasic aliveness beneath its glacial Earth’s surface . The mission extension is welcome tidings , as NASA was plan tocrashJuno into Jupiter subsequently this class to foreclose contaminant of the Jovian organisation .
InSight arrived at Elysium Planitia on Mars in November 2018 . The stationary lander monitor the Martian conditions , detects faintMarsquakes , collects data link up to the planet ’s dynamic atmosphere and magnetic field , and has the casual streamlet - in with adust devil . InSight ’s charge will operate until at least December 2022 , with an summate emphasis place on the monitoring of tectonic activeness .

The lander ’s problematic Heat Probe and Physical Properties instrument ( HP3 ) has been a major worry , requiring much attention from the NASA team and DLR , the German outer space agency responsible for for the probe . knight the bulwark , it was was supposed to dig down to depths reaching 10 feet ( 3 meters).Last intelligence on the mole was that it wascompletely buried , but it ’s still not clean-cut if the equipment can actually drill any deeper . The investigation is probably fine in terms of how it ’s supposed to make for ; the trouble has to do with the character of Martian regolith , call duricrust ( a cement - like compound ) , find by the drill . travel forward , NASA will continue to deploy the mole , but at a lower precedence .
On Feb. 18 , InSight , along with Curiosity , will be link by NASA ’s Perseverance rover . The next - generation bird of passage will need to endure “ seven minutes of holy terror ” during its descent stage , as it attempts to make a soft landing place at Jezero volcanic crater , the situation of a former lake and river delta .
