Another step closer to launch

ICON passes pre-environmental review

Karin Hauck 0 327

After passing its "Pre-Environmental Review” last week, the ICON spacecraft/observatory is now in environmental testing at Orbital ATK in Virginia. We will run a number of tests -- such as vibration and acoustical tests -- over the following weeks that will simulate the launch and space environments that ICON will be exposed to. All the instruments continue to check out well, and we’re getting a lot of time on the observatory. All this testing and reviewing shows us that ICON is in great shape and will be ready to go when launch day arrives this summer. It’s all coming together!

ICON Passes Critical Milestone

A Message from the Principal Investigator

Dr. Thomas Immel 0 777

Two weeks ago, ICON passed a major review at NASA Headquarters, putting it on schedule to launch in ten months. It's a big milestone. ICON was approved to proceed with observatory integration at Orbital ATK in Virginia, meaning that the payload with all the attached instruments was mated to the spacecraft bus, a significant step in the journey to becoming a real science observatory.

2016 will be an exciting year for the ICON mission

2016 will be an exciting year for the ICON mission. This year will see the assembly and test of the complete scientific payload (the collection of instruments and telescopes ICON will carry), the completion of the spacecraft (the main body of the satellite), and when these come together, the assembly and test of the full ICON observatory.

Over the next two months, all of the ICON instruments, the Instrument Control Package (ICP), and other key components will be delivered to the Space Dynamics Laboratory (SDL) in Utah for integration into the payload. Once integrated into a single payload package, it will undergo specialized vibration and vacuum tests to simulate the conditions of launch and operations on orbit.

Once the payload performance has been confirmed, the payload package will be delivered to Orbital ATK in Virginia, who are building the main body of the spacecraft, called the “bus”. Delivery is planned for mid-year, which will give Orbital ATK ample opportunity to test the entire observatory and prepare it for integration with the Pegasus launch vehicle in Spring of 2017.

Meanwhile, the science team will be busy completing the software needed to download and manipulate the data taken by ICON’s instruments to prepare the data pipeline for receipt of real (rather than simulated) data soon after launch in June of 2017.

ICON passes Critical Design Review

Claire Raftery 0 921

During the review, each instrument and system were reviewed, and plans for integration of these systems onto a unified payload finalized. The team was successful in demonstrating their ability to complete these tasks on schedule. All instruments will be delivered to Utah for integration by the end of the calendar year, before delivery to Orbital ATK in Virginia by May 2016, in preparation for launch in June 2017.

Project Manager Bill Craig said “One of the key strengths was the consistency of the team; we were compared to the high quality expected of a Class B mission; a standard we set for ourself at PDR” and P.I. Thomas Immel complemented the team on an outstanding job in preparing and delivering a very successful review.

Congratulations to the entire ICON team… Onwards to Integration!

ICON Confirmed – Proceed to Implementation

Claire Raftery 0 910

On October 29th 2014, the ICON mission was reviewed at NASA Headquarters, where the project presented the status of the project, focusing on the work that had been done to design and formulate the mission to the Science Mission Directorate and the Deputy Administrator for Programs at NASA HQ. At this review ICON was successfully confirmed and was directed to proceed with formulation the mission.

The team has been working together through the successful Mission Preliminary Design Review in July and in the months that followed to reach this key milestones. Preparation for this step has also been a focus for colleagues in the Explorers Office at Goddard Space Flight Center and in the Heliophysics Division at HQ. Everyone involved is excited to proceed with the implementation of the mission!
