Mercury Missions

Stacy Benjamin

Introduction

    • Mercury is the closest planet in our solar system, so it has been one of the hardest planets to explore.
    • There has been only 2 missions to Mercury: “Mariner 10” and the other one is “MESSENGER.”

    Mariner 10

    • Mariner 10 flew by Mercury 3 times in 1974 and 1975.

    • Only 45% of Mercury's surface was mapped.

    LAUNCHING OF MESSENGER

    • MESSENGER stands for MErcury Surface, Space ENvironment, GEochemistry, and Ranging.
    • Messenger was launched by NASA on August 3, 2004.
    • The spacecraft weighed more than 1000 pounds.
    • The MESSENGER has taken more than 250,000 photos, covering the whole planet.

    Objectives for MEssenger

    To know...

    • the composition of Mercury's surface
    • the magnetic field around Mercury
    • the size and state of the core
    • the poles of the planet
    • Mercury's outer sphere

    INformation collected by messenger

    • This mission has shown evidence that there is water and ice under permanent shadow.

    • It gives significant data about characterization of Mercury's magnetic field.

    • This unique mission has given scientists a chance to discover the dramatic changes in Mercury’s comet-like tail.

    • They were also able to see pictures of Mercury’s craters and how it was molded by Volcanic Activity.

    • They had planned to keep collecting data and to continue unrevealing mysteries of Mercury for a whole Earth year, but that lasted for 4 years!

    accomplishments of messenger

    • This mission not only helped scientists to acquire more knowledge about Mercury, it also helped in developing many different technologies. These new technologies will

    • MESSENGER was the first spacecraft to FULLY ENTER Mercury’s orbit, which gave more detailed information.

    • Messenger achieved 100% mapping of Mercury.

    • MESSENGER solved the question if there has been volcanic activity throughout the past years. They also saw all the places where hot lava had been.

    • The spacecraft found out more about the internal structure of Mercury and found out that Mercury’s core is partially liquid.

    Interesting Facts about messeger

    • The spacecraft flew by Earth once, by Venus twice, and by Mercury thrice and it took 6 1/2 years before it entered the orbit of Mercury.

    • To reach Mercury, the spacecraft traveled 7.9 billion kilometers (4.9 billion miles)

    • The spacecraft circles the Sun 15 times in order for it to settle in Mercury’s orbit.

    • This mission is expected to end today, April 30, 2015!!!

    • MESSENGER uses special software called SciBox to simulate its orbit and instruments.
