1977 Out of Ecliptic

• First announcement of a mission to study the
  north and south pole of the Sun was made 1959 and
  finally 1977 again, called Out-of-ecliptic
• Study performed by Dornier System in 1977 and
  1978
• The name International Solar Polar Mission (ISPM)
  was chosen.
• Dornier submitted and won the proposal for this
  challenging spacecraft design
• Later on during the run of phase C/D, a contest
  was held to choose another name.
• ? Winner was Professor Bertotti with the name
  ULYSSES
• Remark the price was two bottles of Champagne

1979 - 1982 ISPM Qualification

• The qualification was reached via a very
  luxurious approach by
• A Structural model spacecraft
• An Engineering Model spacecraft
• A Qualification Model spacecraft
• The structural model was used for a static load
  test to proof the strength of the structure
• ? an accident happened at the preparation during
  lifting of the trolley, the s/c glided back onto
  the frame and as result, an RTG strut was
  damaged.

1981 ISPM SM Integration

• Structure Model arrived at Dornier Cleanroom

7
1981 ISPM QM Integration

• Qualification Model integration at Dornier

8
1979 - 1982 ISPM Qualification

• The Electro Magnetic Compatibility Test at ESTEC
  (June 1982)

9
1979 - 1982 ISPM Qualification

• The qualification Thermal vacuum / thermal
  balance test at Intespace, Toulouse (July
  August 1982)

10
1979 - 1982 ISPM Qualification

• The Magnetic Test at IABG (Sept 1982)

11
1979 - 1982 ISPM Qualification

• After a successful testing a small drink became
  standard (here after magnetic test)

12
1979 - 1982 ISPM Qualification

• The qualification Vibration test at IABG, Munich
  (Sep 1982)

13
1979 - 1982 ISPM Qualification

• The qualification Acoustic Noise test at IABG,
  Munich (Sep 1982)

14
1979 - 1982 ISPM Qualification

• All qualification tests have been successfully
  passed and the go-ahead for the flight model was
  given.
• Some technical data of Ulysses
• Mass 367 kg
• Dimensions 3,24 x 3,33 x 2,14 meters
• Power 284 W at begin of mission, source RTG
• Communication High Gain antenna 1,65m with 20 W
  X-band transmitter
• Data Handling Data storage 45 Mbit tape recorder
  (2 off)
• Reaction Control System with 33,3 kg of Hydrazine
  
• AOCS Spin stabilized (5 rpm) with sun sensors
  and nutation dampers
• Mechanism 1 radial boom 5,5m, 1 axial boom 7,5m
• ? Designed for a life time of 5 years

15
1979 - 1982 ISPM Qualification

• Work at the Check-out Station

16
1983 ISPM Flight Spacecraft

• The flight acceptance testing followed the same
  approach as for the qualification model
• The following tests were performed
• Thermal vacuum / thermal balance test at
  Intespace, Toulouse (July August 1983)
• Electro Magnetic Compatibility Test at ESTEC
  (Sept1983)
• Magnetic Test at IABG (October 1983)
• All tests have been successfully passed but the
  launcher (Shuttle) was not ready and a new,
  unexpected phase started ? Storage

17
1983 ISPM Flight Spacecraft

• The flight model spacecraft has undergone a
  magnetic test at IABG successfully

acceptance tests (Dec 1983)

1985 Recertification 1

• In 1984, NASA announced a launch date for Ulysses
  in May 1986
• Therefore, a recertification phase started in
  January 1985 and lasted till December 1985 with a
  complete verification programme. This phase was
  performed in the ESTEC premises.
• Some Instruments were returned 1983 for upgrading
  internally and had to be integrated and
  functionally tested again during this period.
• In December 1985 everything was ready and Ulysses
  was shipped to the Kennedy Space Centre. The team
  arrived January 3, 1986.

20
1986 Launch Campaign 1

• The launch campaign commenced in January 1986
  with the full team deployed to the Kennedy Space
  Centre, Florida - USA
• All final functional testing was running well
  till January 28, when the accident with the
  Orbiter Challenger happened
• ? continuation for Ulysses was open.
• Work had continued for some weeks at KSC, but
  then finally stopped by NASA and Ulysses brought
  back to Europe
• ? another storage period was initiated with an
  open status
• Most of the instruments were returned to the
  Investigators for special calibration work

21
1988 - 1990 Recertification 2

• The recertification phase 2 started beginning
  1988 until March 1990.
• It contained a short thermal vacuum test at ESTEC
  and a spin balance test.
• This test was necessary, because the launcher
  approach was changed from Centaur upper stage to
  IUS and PAM-S, which had a spin rate of 60 rpm
  before separation of the spacecraft.

22
1988 - 1990 Recertification 2

• Interface Clarification Meeting at McDonald
  Douglas (1988) with PAM-S

23
1988 - 1990 Recertification 2

• Visiting the Experimenters in USA 1988, before
  re-delivering to Europe

24
1988 - 1990 Recertification 2

• The end of the recertification phase at ESTEC in
  March 1990

25
1990 Launch Campaign 2

• The launch campaign started in May 1990 and
  finished with the successful launch on 6 October
  1990
• The spacecraft was transported by a flight from
  Amsterdam to Orlando, Florida and then by trucks
  to the Kennedy Space Centre.
• Unloading of the trucks was performed by the
  heavy gang of the KSC, but also the entire team
  has been involved.
