ISEE-3 Trajectory Correction Maneuver
ISEE-3 Status Report 7 July 2014 (evening)
“If all goes according to plan on Tuesday, 8 July, we will conduct the Trajectory Correction Maneuver (TCM). This will require a much longer firing of the spacecraft’s thrusters. Our window at Arecibo opens at 12:42 pm EDT and extends until 3:29 pm EDT. If the burn is a success we will follow up with another ranging session using the DSN to get an exact measure of the spacecraft’s position, trajectory, and speed. After that we should be good to go for our lunar flyby on 10 August. After the last technical tag-up for today it looks like TCM will be 432-435 pulses fired in 7 segments with a total delta V of approximately 7 m/sec.”
Keith’s update: We managed to conduct the first segment but encountered problems with the second and halted the remainder of segment firings. We’re looking at data and formulating a plan for tomorrow.
If NASA approves of our paperwork, though I got it in really late! NASA HQ has been very supportive of our efforts!
Late? It’s not like you were BUSY, Dennis…
BTW do you guys have to get approval for every single thing you do? Each step? I guess I supposed they had turned you loose.
We have three ATP – Authorization to Proceed reviews. ATP-3 covers course correction burns.
Is this really the only thing going on in space these days? I thought this was NASA Watch – not “Boys with space toys” watch. It’s cool you guys are doing this but it’s getting to be an obsession and this site is getting boring!
Then go read another website while we have fun.
Keith, I think what you, Dennis and the team are doing is REALLY neat, and the first of its kind. While the internet is geared toward “that was nice 5 seconds ago, what’s NEW?” this is an exciting as-it-happens story with all the ups, downs, twists and turns.
What if EVERY space blog/news site were running its own space program? I think this is much more valuable than making sure the latest stream of canned press releases is posted so we can whine about them.
Keep up the good work,
Jeff
Hey, I think it’s interesting. There is a time to think, and a time to act.
ISEE-3 is a NASA spacecraft and its revival and recovery (knock on wood) are historic. I come to the site in eager anticipation of an informative update from the people who are actually doing the work each day. I’m gaining an understanding and perspective on the actual work of running a spacecraft that I’ve never had before and I’m very grateful for that.
Thank you, Dennis & Keith!
Sorry just so sick of all the articles about this old satelite
It’s like hey..I got my dad’s old Chevy running
Great. Nice for you
Next…please.. Next.
And yet you expended the effort to make such a valueless comment.
