00:00:00,520 --> 00:00:03,240
NASA Launch Commentator Josh Finch: We have
scrubbed for tonight’s attempt, which was

2
00:00:03,240 --> 00:00:07,629
targeted to go at 3:53, but we expired our
time in the window.

3
00:00:07,629 --> 00:00:09,350
Mic, can you tell us a little more?

4
00:00:09,350 --> 00:00:11,090
Mic Woltman, NASA Launch Services Program:
Yeah, absolutely, Josh.

5
00:00:11,090 --> 00:00:15,250
Teams worked very hard this evening, diligently
getting through the launch process, looking

6
00:00:15,250 --> 00:00:18,630
at everything they had to to get into the
terminal count this evening.

7
00:00:18,630 --> 00:00:24,450
As we picked up the count at T-4, and got
into terminal count, the team received a gaseous

8
00:00:24,450 --> 00:00:28,600
helium red pressure alarm that kicked them
out.

9
00:00:28,600 --> 00:00:32,500
That was what you heard the “hold, hold,
hold” on the countdown net was for.

10
00:00:32,500 --> 00:00:35,220
The team is evaluating that and looking at
it.

11
00:00:35,220 --> 00:00:38,630
Unfortunately, we didn’t have enough time
this evening to go troubleshoot that and try

12
00:00:38,630 --> 00:00:40,290
again for launch.

13
00:00:40,290 --> 00:00:46,829
So we’re going to lean forward here and
plan for a 24-hour turnaround tomorrow for

14
00:00:46,829 --> 00:00:48,820
a launch time of 3:31 a.m.

15
00:00:48,820 --> 00:00:54,370
However, that is contingent upon the detanking
process this evening and the team continuing

16
00:00:54,370 --> 00:00:58,870
their evaluation of the gaseous helium reg
alarm.

17
00:00:58,870 --> 00:01:02,310
If they determine or find anything that they
can’t get ready for tomorrow’s launch

18
00:01:02,310 --> 00:01:08,299
attempt, the launch management team will get
together and determine if we maintain that

19
00:01:08,299 --> 00:01:12,100
24-hour turnaround or if we go to a 48-hour
turnaround.

20
00:01:12,100 --> 00:01:13,579
So that’s where we are right now.

21
00:01:13,579 --> 00:01:17,649
Unfortunately, we did scrub this evening due
to this issue, but the teams will continue

22
00:01:17,649 --> 00:01:23,369
to work this problem and move forward to get
Parker Solar Probe on its way to the sun.

23
00:01:23,369 --> 00:01:25,310
Finch: Thank you, Mic, for the update.

24
00:01:25,310 --> 00:01:27,700
With that update, we’ll now go back to Marie
Lewis.

25
00:01:27,700 --> 00:01:31,680
Marie Lewis, NASA Communications: Josh and
Mic, thank you so much for keeping us updated.

26
00:01:31,680 --> 00:01:35,999
As you just heard, today’s launch attempt
has been scrubbed, and this concludes our

27
00:01:35,999 --> 00:01:39,459
coverage of today’s Parker Solar Probe launch
attempt.

28
00:01:39,459 --> 00:01:44,359

mission, visit nasa.gov.

29
00:01:44,359 --> 00:01:47,999
Thank you for getting up so early with us,
and we invite you to rejoin us when we try
