23-Jan-99 | Delta flight 265 – Mars Polar Lander / Deep Space 2

Mars Polar Lander and Deep Space 2 successfully launched aboard a Delta 7425 launch vehicle from Cape Canaveral on 3 January, 1999. They are on course for arrival at Mars in less than 0 days.

MPL will soft-land at the Martian south pole to study climate history and composition of the polar ice cap. DS-2 consists of two micro-probes which will impact Mars and penetrate to a depth of up to one metre in order to analyse sub-surface soil. The Delta 7425 was extremely accurate, such that MPL’s first TCM burn on 21 January changed its velocity by about 16 m/s, mostly in order to remove a launch bias used to prevent the Star 48 third stage from impacting Mars.

20-Jan-99 | Web site news

History of the Delta Launch Vehicle is undergoing a slight expansion and reorganisation. The Schedule has been divided from the rest of the Flight Log for faster downloading. Meanwhile, the Flight Log is receiving the addition of spacecraft weights and orbital parameters for all flights. Corrections and comments are, as always, welcome.

04-Jan-99 | Globalstar schedule

Globalstar has scheduled a total of six flights on Delta rockets this year. This will make for a very busy schedule as the grand total will be 18 Delta II and 5 Delta III launches expected in 1999.
