On this day in space! Feb. 11, 2010: NASA launches Solar Dynamics Observatory

On Feb. 11, 2010, NASA launched a spacecraft to study the inner workings of the sun. The new Solar Dynamics Observatory was made to take the most detailed and comprehensive measurements of the sun ever. 

The satellite orbits Earth, but its orbit allows it to look at the sun continuously. It looks for activity like sunspots and solar flares, but it also studies the sun's magnetic field.

By better understanding the sun's crazy and warped magnetic fields, scientists hope to better predict space weather events that spew harmful radiation toward Earth. 

The Solar Dynamics Observatory launched just in time to see the sun during the peak of its 11-year solar cycle

    Just so you know, the X-15 took off from Edwards AFB under the wing of a B-52 & was airdropped over Delamar Dry Lake, Nevada. The flight to the altitude record wasn't planned, but the rocket engine burned for two seconds longer than expected. The test flight was scheduled to peak at 280,000', but actually reached 314, 750' due to the extra rocket burn time.

    Misleading wording. Bob White did not set the world altitude record on July 17th, 1962. Four Astronauts and two cosmonauts had flown higher prior to his flight. One could say it was the highest manned flight of a winged craft. But that's not the wording that was used.

    On this date in 1969, I was part of NASA Apollo Team

    Contributed to Experiments in orbit and on Surface of Moon (ALSEP) etc.also trained astronauts

    Studied containation on and ouside Spacecraft.

    The Moon gave me employment to work for 5 Years on exciting Human Space flight Programs Skylab, Planning of Space Station and Space Shuttle

    I received Apollo Achievement Award from NASA dated July 20, 1969.

    Thanks Hanneke Weitering for today's Historic post

    "Allegedly, the moon turns green because of its close proximity to Uranus"

    I'm sorry about that. I hear they have been investigating x-rays from the same source. I had no idea. I'll get a doctor to check into it.

    Sorry everyone.

    Sorry...
