Before we can deflect a killer asteroid, we must know its mass.
Before we can deflect a killer asteroid, we must know its mass. For small objects, traditional tracking fails. A daring new dual-spacecraft maneuver aims to solve the problem.
Estimating the mass of a Potentially Hazardous Asteroid (PHA) is the single most important metric after determining its trajectory. If we need to send a kinetic impactor to knock it off course, we need to know exactly how heavy it is to calculate the necessary force.

For two decades, the bright, striped "zebra pattern" of the Crab Pulsar baffled scientists.
For two decades, the bright, striped "zebra pattern" of the Crab Pulsar baffled scientists. Now, the mystery has been solved by an invisible battle between plasma and gravity.
In the year 1054, Chinese and Japanese astronomers witnessed a new star appear in the sky. Today, we know it as the Crab Nebula—the remnants of a violent supernova. At its very center sits the Crab Pulsar, a rapidly spinning neutron star emitting beams of radiation.

A new model reveals exactly how long Earth microbes can survive the Mars journey.
Searching for life on Mars means making sure we don't accidentally bring our own. A new model reveals exactly how long Earth microbes can survive the brutal journey.
Searching for past or present life on Mars is the sole driving force behind every mission we send to the red planet, from orbiters to landers to rovers. However, there remains a persistent concern: forward contamination.
