When imaging faint objects such as distant stars or exoplanets, capturing every last bit of light is crucial to get the most out of a scientific mission. These cameras must be extremely low-noise, and be able to detect the smallest quantities of light—single photons. Superconducting cameras excel in both of these criteria, but have historically … Read more
Planetary science missions using small spacecraft will be required to perform challenging propulsive maneuvers—such as achieving planetary escape velocities, orbit capture, and more—that require a velocity change (delta-v) capability well in excess of typical commercial needs and the current state-of-the-art. Therefore, the #1 enabling technology for these small spacecraft missions is an electric propulsion system … Read more
In the design of APES, one major trade-off had to be made. For the magnetic field geometry to work properly, the instrument can only observe in one direction. This concept works well if the goal is just to measure the precipitating (downgoing) electrons in the aurora that ultimately hit the atmosphere. However, we know that … Read more
6 min read US, Germany Partnering on Mission to Track Earth’s Water Movement The Gravity Recovery and Climate Experiment-Continuity mission will extend a decades-long record of following shifting water masses using gravity measurements. NASA and the German Space Agency at DLR (German Aerospace Center) have agreed to jointly build, launch, and operate a pair of … Read more
Do we have enough fuel to get to our destination? This is probably one of the first questions that comes to mind whenever your family gets ready to embark on a road trip. If the trip is long, you will need to visit gas stations along your route to refuel during your travel. NASA is … Read more
Of the approximately 5,500 exoplanets discovered to date, many have been found to orbit very close to their parent stars. These close-in planets provide a unique opportunity to observe in detail the phenomena critical to the development and evolution of our own solar system, including atmospheric mass loss and interactions with the host star. NASA’s … Read more
Traditional space-based thermal sensors rely on bulky cryogenic coolers to remain at a constant temperature of about -300 degrees Fahrenheit. Cryogenic coolers add a lot of mass to space instruments. For example, the Moderate Resolution Imaging Spectroradiometer (MODIS), a space-based infrared radiometer serving aboard NASA’s Aqua and Terra satellites, weighs more than 500 pounds.
