 | | Because of the geometry of Mars Express' orbit and the location of the rovers during August, both the Spirit passes were 'Canister Mode' tests taken with Mars Express in the higher altitude in its orbital ellipse "to simulate data collection during an EDL event," says Arnold. |
 | | Although Mars Express and Opportunity had another 128 KBPS test 'date' August 10, that link-up was canceled by the MER team, because, says Arnold, of conflicting science and onboard power supply constraints. |
 | | As seamless and easy as these telecom link-ups between Mars Express and the rovers this month may sound, the tests that proved the protocol and the ability for a European mission and a NASA mission to successfully communicate with each other at Mars required years of groundwork on Earth. |
