　　The spacecraft was launched on Monday，November 18，2017，from Cape Canaveral，Florida．The trip to Mars takes about 10 months．and MAVEN is scheduled to go into orbit in September 2017．It is the first spacecraft created with the purpose of studying Mars' atmosphere．Its wingspan(翼展)measures 37．5 feet not quite the length of a school bus, and it weighs 1991 pounds about the same amount as a small car．MAVEN is equipped with eight different tools to measure and study the planet’s atmosphere．To collect information，it will fly in orbit as fast as 3278 miles per hour，and as slow as 93 miles per hour．

　　Once it arrived at Mars，MAVEN will have plenty of company．The spacecraft Curiosity is still walking around the planet’s rocky surface，studying the geology，chemistry and possible biology there．NASA currently has a number of spacecrafts getting unique views of Mars with powerful cameras and telescopes．These missions are all slow，steady steps．forward to discover Mars secret past．While the results may not be revealed for some time，an exciting exploration is on the way．
