The Optical Orbital Debris Spotter is capable of detecting debris with sizes as small as about 0.01 centimeters in the vicinity of a host spacecraft for near real-time damage attribution and characterization of dense debris fields.  Credit: Naval Research Laboratory (NRL)

Earth orbiting clutter comes in all sizes: upper stages to paint chips to small shards of spacecraft leftovers. The number of human-made debris objects orbiting the Earth continues to increase at a worrisome rate, with objects smaller than one centimeter (cm) exceeding 100 million. Put at risk from some high-speed flotsam are operating satellites and […]

The U.S. Congressional Budget Office has taken a look at House Resolution 1508 – the Space Resource Exploration and Utilization Act of 2015. That bill would establish certain policies and guidelines regarding the development of space resources by nonfederal entities. Existing international agreements authorize such activities under certain conditions, including requirements for national regulatory regimes […]

NASA’s Curiosity rover is experiencing excessive wheel slippage. So much so that controllers of the Mars machinery are studying new driving tactics. Also, the rover is tilted 21 degrees, “the highest tilt of the mission so far,” explains Ken Herkenhoff of the U.S. Geological Survey’s Astrogeology Science Center in Flagstaff, Arizona. Curiosity is on the […]

The big space question of today: Can future generations ever be as excited about space as past generations? To look for the answer, take in this episode of “Engineering Live” offered by Electronic Component News (ECN). The premise of this video is that the 1960s were arguably the most fascinating time in the world of […]


  NASA’s veteran Mars rover – Opportunity – is taking in a perplexing geological feature on the Red Planet. An elongated, shallow crater dubbed “Spirit of St. Louis” has a rock “spire” within the crater. The rocky feature toward the far end of the crater is about 7 to 10 feet (2 to 3 meters) […]
