|The space community experienced both the highs and lows of space travel this past week.
The lows were the death of a Virgin Galactic pilot aboard Spaceship Two on Friday and the explosion of the Orbital Sciences Antares rocket shortly after liftoff from Wallops Island, VA earlier in the week.
But, there were positives as well. The Russians successfully launched a Progress supply spacecraft to the International Space Station shortly after the Antares mishap. The Chinese sent a spacecraft around the Moon and landed it back on Earth on Saturday morning. And, SpaceX successfully returned science experiments conducted on the ISS via its Dragon spacecraft.
