INFORMAL ELECTRONIC NEWSLETTER FOR THE EUVE SCIENCE PAYLOAD
----------------------------------------------------------------
Volume 1, Number 2 Aug 5, 1991
----------------------------------------------------------------
EUVE Launch Date
----------------
The EUVE Launch date is December 12, 1991. The Pre-Environmental
Review for the spacecraft is being held August 1 and 2. This is a
major milestone towards the launch.
Science Payload
---------------
The EUVE Science Payload is in excellent condition. The ion pump
power supply, which had a problem in July, has been repaired and
re-installed. The dry nitrogen pressure in one of the instru-
ments has been found to bleed down too rapidly given the launch
tower sequence. A possible leak in the valve is being investi-
gated, and the procedure for dry nitrogen purging of the instru-
ments on the pad is being reviewed. Work on the backup filters
and detectors is proceeding.
Guest Observer Program
----------------------
Work has begun on re-furbishment of the offices to be used by
Guest Observers while at UC Berkeley. Based on the launch date
of Dec 12, 1991, The key dates for the Guest Observer Program are:
09/15/91 Release by NASA of the NASA Research Announcement
09/20/91 Distribution of Guest Observer Handbook
12/12/91 EUVE Launch
01/92 Guest Observer proposals due
05/92 Time allocations and support announced
08/92 Start of EUVE Guest Observer Phase
EUVE Sky Survey Science Software Development
--------------------------------------------
Rev 7.1 of the End to End software has been released and re-
viewed. No major deficiencies for post launch operations were
found by the review board. The next release of the software, Rev
7.2, will occur just prior to the next major simulation in early
September and will include modifications to the EES needed to
support the simulations and correct bugs currently in the EES.
Calendar of forthcoming events
------------------------------
The indicated dates are planning dates as of Aug 1, 1991. For
