Planck and
Herschel have been
launched together with an Ariane 5 from Europe's Spaceport in French
Guiana.
|
|
|
Planck and Herschel will be
launched on April 16, 2009. And each of them will have an SREM aboard.
|
|
|
SREM is planed to be switched-on on Wednesday, 07 May, 2008.
|
|
|
The GIOVE-B satellite with a SREM aboard
was successfully launched with a Soyuz/Fregat launcher from Baikonur
cosmodrome in Kazakhstan by launch operator Starsem. Lift-off occurred at
04:16 local time on 27 April (00:16 Central European Summer Time).
|
|
|
The SREM web site was updated with the data from SREM aboard Rosetta. After
some modifications of the onboard software to control SREM, which were
carried out during the summer, the instrument was switched on on 21 October
2004 and is planed to be continuously operated in the future.
|
|
|
Rosetta was successfully launched from
Europe's Spaceport at Kourou this morning at 08:17 CET.
|
|
|
The launch of Flight
158 with the Rosetta spacecraft is delayed by a few
days.
|
|
SREM aboard Rosetta
|
|
|
|
The launch of an SREM aboard
Rosetta
is now scheduled for February 2004!
|
|
|
The launch of Rosetta has been postponed by a year or so.
|
|
|
Having considered the conclusions of the Review Board set up to advise on
the launch of Rosetta, Arianespace and the European Space Agency have
decided on a postponement.
|
|
|
Arianespace has decided to create
a Review Board to make a decision on Tuesday, January 14 regarding
Rosetta's launch date.
|
|
|
The IREM data is now available on this site at the
DATA section.
The launch of an SREM aboard
Rosetta
is scheduled for 13 January 2003!
|
|
|
Already 9 hours after launch of INTEGRAL, IREM (Integral's Radiation Environment
Monitor) was switched on and is working fine since then. The following
graphs show IREM count rates for the first 5 perigee passages.
1. perige passage,
2. perige passage,
3. perige passage,
4. perige passage,
5. perige passage
S14 shows protons at > 20 MeV and TC3 shows electrons at > 0.5 MeV plus the
protons.

|
|
The main test phase of PROBA 1 has been completed and SREM is planned to be
operated now on a regular basis. New SREM data can be expected to be
processed and put on this site in intervalls of approximately 10 days.
|
|
|
Since December 2001 SREM was continued to be operated only sporadically. The
data accumulated so far is now available for download in the
DATA
section.
A few
PowerPoint slides showing some of the data are also available.
|
|
|
Commissioning phase with only sporadic operation of SREM is still continuing.
So far SREM was only switched on a
few times.
|
|
|
While commissioning tests are carried out on PROBA 1, SREM is switched off
since 8 November 2001. SREM will be switched on again after the tests have
been finished.
|
|
|
More test runs of PROBA1/SREM have been carried between November 1 and 7.
The measurements have been interrupted a few times by the occurrence of a
'watch-dog elapsed' error. Nevertheless the gathered data looks good!
Results are summarized in a short
report.
|
|
|
Short test runs of PROBA1/SREM have been carried out on October 28 and 29.
Preliminary results indicate that the instrument works well.

Launch of Indian rocket PSLV-C3 with
PROBA aboard!!
Updates on the status can be found at the
home page of the Indian Space Research Organization
ISRO and at the
PROBA home page.
|
|
|
Launch of Proba now fixed to
22 October 2001
.
|
|
|
Launch of Proba delayed again. New launch window between
8 and 14 October 2001
.
|
|
|
SREM web site migrated to new server!
|
|
|
Proba flight acceptance review. New schedule: ship 27 Aug - 1 Sept, and
launch 25
Sept. However, the board did not think risks should be introduced by
trying to meet the schedule. So there will be a delta review just before
the shipping.
|
|
|
Launch of Integral delayed. New launch date is
17 October 2002
.
|
|
|
Launch of PROBA with Indian rocket PSLV-C3 scheduled for
August 2001.
PROBA will be launched together with the
BIRD
satellite from DLR.
|
|
|
Final report on Strv1c/d anomaly was published and is available on
request.
In summary: Recovery of the missions is not expected!!
|
|
|
The Strv1c/d anomaly was reproduced with flight spare hardware. Some further
tests are needed to identify precisely which component has failed and
determine the failure mechanism. See
status report.
The target for the final report of the investigation is now 15 March 2001.
|
|
|
Ongoing investigations of the cause of the Strv1c/d receiver problem. Final
results not to be expected before end of February 2001. See
status report.
|
|
|
Cause for Strv1c/d receiver problem not identified yet, but progress was
made in eliminating possibilities and focusing the investigation. See
status report.
|
|
|
Problems with Strv1c/d spacecrafts. Receivers powered down between
link sessions. Tests are going on to identify the cause. See
status report.
|
|
|
Routine operation of the Strv1c instrument has started yesterday. New SREM
data is expected to arrive in a few days.
|
|
|
First data from SREM. During the check-out of all STRV-1c & d
experiments, SREM has been switched on and was operated for a short period.
The data indicate that SREM is fine and works well. A
summary report is available.

Successful
launch of Strv-1c and Strv-1d !!

The launch of Arianespace Flight 135 has been postponed for one day
following an anomaly in the ground-based infrastructure at the Spaceport in
French Guiana. This anomaly, which affected the telemetry link with the
PAS-1R satellite, occurred during the final countdown on Nov. 14.
As a result, Flight 135 has been delayed for 24 hours. The launch window is
(Paris time) from 2:07 a.m. to 3:03 a.m. on November 16. |

Flight 135's Ariane 5G moves from the integration building to the final
assembly on the new mobile launch table. In foreground is the no. 1
Ariane 5 launch table, which will be moved into the integration building
to prepare for the next Ariane 5 mission.

|
There was a delay in the shipment of Panamsat to French Guiana and
associated with this Arianespace introduced an Ariane-4 launch into the gap
in the manifest. This launch occurred successfully at the weekend, and
another Ariane-4 is still scheduled at the end of the month. The STRV
flight, Ariane-507, is now scheduled for 14 November, 2000
