Beagle 2

 2003-022


Beagle 2 is the UK lander for Mars Express. Mass is 68 kg. Landed mass 33 kg; back cover 13 kg. Decelerator is 16 kg.

Astrium/Martin-Baker lander.

Separates from Mars Express at MOI-5d (Dec 19 for a Jun 2 launch) Land at 11.53N 269.47W (postflight values) in Isidis Planitia 2003 Dec 25. Signals were not received from Beagle-2 after ejection. The mission team claimed it is possible that thinner than expected Martian atmosphere caused the spacecraft to crash, but an independent inquiry disagreed with this analysis and suggested that any of several design problems with the vehicle could have caused the failure, including parachute and airbag vulnerabilities.

Double cone heat shield

Disc + 4 circular panels.

Entry at 5.5 km/s and -16.5 deg (original plan -18 degrees before final mass update).

Nominal values 120.0 km, 277.5W 9.893N at 5.4074 km/s, -16.6 deg relative, or 5.6417 km/s in. Azimuth 73 deg.

Per Cramm R, Gamo J, Baiske R 2004, ISSFD meeting, Reconstructed Beagle 2 Trajectory, entry time was 0251:22, -16.63 deg relative, over 277.04 +11.14N (vs 11.21 nominal).

Agila 2

 1997-042A


The Phillipine Agila Satellite Inc. (PASI), Makati was formed in Jun 1994. Philippine Long Distance Telephone Co (PLDT) broke off in 1994 and formed Mabuhay Philippine Satellite Corp, (MPSC), Manila.

Mabuhay Philippines Satellite Corp. is buying a Loral satellite for domestic Philippines communications, to be launched in late 1996.

In October 1997 Agila was moved to 146E after Japan said it was interfering with Superbird C; Phillipines did not have ITU clearance to broadcast at Ku band from the 144E slot.

In 2009 MPSC was bought by Asia Broadcast Satellite of Hong Kong and Agila 2 was renamed ABS 5. In 2011 the satellite was moved to 3W and renamed ABS 3.
