Today is a big day for us: mechanical integration onto the spacecraft. Chances of seeing our engineers via the live clean room camera. youtube.com/live/uPL8UEU3S…

Electronics box integrated, harness ongoing. And the YouTube stream link has changed. youtube.com/watch?v=J-Xev5…

Very happy to report that today we powered on the MAG instrument on the spacecraft and took good science data. Great work from everyone Johns Hopkins APL LASP and of course Imperial Physics - Go IMAP!

This week Alan, Chris and Mihir have travelled to Johns Hopkins APL with the MAG engineering model to conduct some additional EMC testing and close an outstanding issue before flight. This is going smoothly. Thanks to everyone at APL for the support.

Wave back to Alan and Mihir in the cleanroom with IMAP, as they return the MAG sensors following EMC testing. Follow along right now via the live feed below. imap.princeton.edu/clean-room-vid…

Today we remotely powered the flight model while it was connected to the spacecraft - great team work from Imperial Physics , Johns Hopkins APL and LASP . A bit stressful in places but a successful test and the instrument performed perfectly.

Today MAG was powered up on the spacecraft, along with two other instruments, to help us get ready for early in flight operations. A very smooth experience with nominal performance. Thanks to the MAG, spacecraft and payload operations center teams.

Today we updated the software on the flight model instrument to v4.01, verified the upload and successfully booted into the new version. A calm and smooth experience, just how we like it. And yes we do still have blackboards.

We have just updated the software on the flight instrument to Alastair's latest creation, v4.05. This is feature complete and is the version we expect to fly. It also brings a key improvement: data compression which will double the amount of burst mode data we can return.
