On April 15, 2005, NASA launched a spacecraft on a mission to rendezvous with a small communications satellite. The launch went according to plan, but the mission ended abruptly when the spacecraft collided with the satellite. 

The mission was known as DART, which is short for Demonstration for Autonomous Rendezvous Technology. Its objective was to demonstrate that a fully automated and uncrewed spacecraft could rendezvous with another spacecraft in orbit. But the two spacecraft were not supposed to make contact.

When DART approached its target, it ran out of fuel and inadvertently bumped into it. 

Investigators determined that DART's thrusters had been firing excessively because of a problem with its navigation system. It was a soft collision, and neither of the spacecraft were noticeably damaged.

    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

    "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...
