Mars Odyssey

Mars Odyssey was an orbiter launched in 2001 to Mars by a Delta II Rocket. It was kind of a lucky spacecraft because it didn't run to any problems before encountering the planet unlike the previous orbiter, Mars Climate Orbiter and it now operated for about 21 years from launch to today or 20 and 1/2 years of operation or Mars, being the longest living interplanetary space probe. It earned it's longevity badge on December 2010. Mars Odyssey was built a bit of like the Mars Climate Orbiter but this time, with a boom and some new instruments on the orbiter. It's similarities with the MCO are the solar panels and antenna. It was launched on a Delta II 7925 on April 7, 2001 to Mars. It reached Mars on October. It also finished aerobraking faster than Mars Global Surveyor and Mars Global Surveyor also took the first picture of a spacecraft in orbit of Mars by picturing both this spacecraft (Mars Odyssey) by 2 times and Mars Express by 1 time. It relayed the Mars Exploration Rovers, Phoenix Lander, Mars Science Laboratory (Curiosity Rover) and the Perserverance rover (I think). It has also pictured Phobos. Here in SR2, this is Version 2.0 of Mars Odyssey. Now the new spacecraft has a boom with struts made of fuel tanks (the old version had just pistons as the boom), all of the instruments in real life are put here in SR2, the antenna extends like IRL, the Solar Panel is bigger and there are RCS thrusters and the new spirit engines on the spacecraft to make precise corrections now. It has been given 2 extra activation groups:
AG 11: Spacecraft RCS
AG 12: Open GRS Door
Also some parts on the launch pad and the orbiter have been XML Edited. I also removed the hidden eject motors so that I can make the interstage on the Delta II stronger.
