NASA’s daring mission to discover Jupiter’s icy moon is going through tight schedules getting devices put in and prepared for the deliberate 2024 launch.
Europa is a very tantalizing vacation spot as a result of scientists imagine that, beneath its icy crust, the moon hides a worldwide ocean — and that the ocean would be the type of place the place life might survive. That is why NASA designed its Europa Clipper mission, meant to launch in 2024, arrive at Jupiter in 2030, and fly previous Europa dozens of occasions. Engineers are assembling the spacecraft in a clear room in NASA’s Jet Propulsion Laboratory (JPL) in California, however lots of the mission’s devices are not on time, beginning to trigger severe considerations.
“You must acknowledge that each particular person you see in a bunny go well with is a hero,” Curtis Niebur, a undertaking scientist at NASA, mentioned throughout a gathering of the Outer Planets Evaluation Group held on Nov. 16, referring to the protecting gear engineers put on within the clear room. “That ATLO crew is bending over backwards to accommodate all the late deliveries, together with devices.” (ATLO refers to Meeting, Take a look at and Launch Operations; you’ll be able to watch the meeting course of reside, because of a broadcast from JPL.)

Europa Clipper will carry 10 key devices, together with cameras, magnetic subject sensors and units to establish supplies on the moon’s floor. However with lower than two years to go earlier than launch, solely three of these devices have been put in on the primary spacecraft physique, and 5 have not but arrived at JPL.
And time is getting tight.
“The ATLO individuals have expended all of their magic,” Niebur mentioned. “Any additional delay goes to eat immediately into the schedule margin now we have.”
In the course of the assembly, Tim Larson, undertaking supervisor for Europa Clipper at JPL, ran via the standing of every instrument, in addition to different key spacecraft parts. The spacecraft’s solar array panels are being related within the Netherlands, for instance, whereas two devices are anticipated to reach at JPL inside the subsequent couple of months. Because the presentation, JPL announced that engineers have put in the 4 response wheels that may hold the spacecraft correctly pointed. And engineers at JPL have acquired the spacecraft’s high-gain antenna and a dust analyzer, Larson mentioned. Â
One instrument, the Mapping Imaging Spectrometer for Europa (MISE), is especially worrying since engineers aren’t assured sufficient to provide the instrument a goal supply date. MISE is designed to research mild reflecting off Europa’s ice to map the composition of the floor. However the testing marketing campaign has revealed a number of points for engineers to work via, Larson mentioned. “That is the one instrument proper now the place now we have open points which might be getting work and we do not have a strong sense but on how lengthy it’s going to take to get completed up.”
The meeting course of does have some flexibility, he famous, since engineers can rearrange the order of their duties. However that solely goes thus far.
“It is essential that all of them keep on with these supply schedules,” Larson mentioned of the devices nonetheless in testing. “If we begin slipping from these, then we begin discovering tough choices now we have to make in how one can accommodate them.”
