[Ibex-public-announcements] IBEX Successful Return to Nominal Operations

[Reno, Michelle]

Hello Team!

 

As of 1607 UTC today, IBEX is in Science State, Payload HVSCI mode and
we are happily collecting data. We were at ~36Re ascending (altitude)
when we entered HVSCI. Voltages, currents and counts are all nominal.

 

We have successfully completed the Orbit Maintenance Maneuver procedure
and will stay in this orbit for the next decade or so, give or take a
few years.

 

Many thanks to the many dedicated team members at Applied Defense
Solutions, Orbital Sciences, Southwest Research Institute and the
University of New Hampshire. Your hard work and diligent attention to
detail is the reason why this operation went so smoothly. It's been a
pleasure working with you on this operation!

 

Go IBEX!

Hello Team!

 

The delta-V maneuvers went so well that we were able to accelerate our
return to science! The three delta-V maneuvers have placed us in an
orbit that is lunar synchronous and therefore extremely stable. It has
no eclipses >4 hours for more than 20 years, has perigee above the
radiation belts and geosynchronous, and rotates the hole in the maps due
to the Magnetosphere away from the Helionose. This orbit far surpasses
our requirements and will ensure we do not need another orbit
maintenance maneuver for more than a decade.

 

This morning we have successfully finished all of the maneuvers
associated with the Orbit Maintenance Maneuver Procedure. We have spun
down to our nominal ops spin rate of 4rpm. We have repointed to ~3.4
degrees off the sun, which is the correct orientation for science at
this position in our orbit. All spacecraft systems are nominal.

 

Tomorrow we will turn on the payload and return to nominal operations.

Hello Team!

 

Our 3rd delta-V maneuver was also nominal!

 

At 1100 UTC today we performed our 3rd 600 second delta-V maneuver.
Temperatures, pressures and spacecraft telemetry were all nominal and
the burn executed as planned. 

 

We will now collect Doppler data to get an OD solution for our long-term
orbit.

Dates after ADV3 are contingent upon achieving target orbit with 3
maneuvers. I will keep you posted.

Hello Team!

 

Our orbit maintenance maneuver continues to proceed nominally!

 

At 1900 UTC today we performed our 2nd 600 second delta-V maneuver.
Temperatures, pressures and spacecraft telemetry were all nominal and
the burn executed as planned. 

 

Tomorrow morning at 1100 UTC we will perform our 3rd 600s delta-V
maneuver.

Hello Team!

 

I am thrilled to say our first delta-V maneuver was successful.

 

At 2000 UTC today we performed a 600 second delta-V maneuver.
Temperatures, pressures and spacecraft telemetry were all nominal and
the burn executed as planned. 

 

We will collect telemetry & Doppler data over the next few days and get
an OD-based thruster calibration after we go through perigee. We will
use this knowledge to tune the duration of our final delta-V maneuver.

Hello Team!

 

I am happy to report a very successful day at the IBEX MOC. Today's
maneuvers went off without a hitch.

 

At 0430 UTC this morning we began the IBEX Maintenance Maneuver
Procedure. The payload was in LVENG with the sensors off as commanded in
the orbit 127 ATS. We repointed to align the spacecraft with the
velocity vector at the 6/17 apogee. All systems were verified, the
pointing vector was approved and the SSR was dumped. Then the full
payload & star tracker were turned off, and will remain off throughout
the delta-V maneuvers. The spacecraft was spun up to 22rpm to remain
spin stabilized for the maneuvers.

 

All systems are green, we are power positive, our spin rate and pointing
are adjusted and we are ready to move on to continue on to our first
delta-V maneuver on June 8.

June 5

Hi team,

 

We have given the official 'Go' for the orbit maintenance maneuver
procedure. We will begin on Sunday, June 5th by repointing to align the
spacecraft with the velocity vector at apogee. After pointing is
approved we will spin up to 22rpm for spin stabilization during the
delta-V maneuvers.
