Is pulsar timing a viable positioning system for solar system missions
I was reading one of the questions about a version of GPS around Mars, and I started wondering about a Solar system wide positioning system -- large satellites with accurate clocks and powerful ...
Do crew movements or movement of other objects ever affect space or Earth observation experiments staged on the outside of ISS?
The ISS serves as a platform for both Earth and astronomical observational instrumentation. Do routine movements of the crew or other objects ever cause problems for these observations through ...
At what wavelengths and for what particle types have astronomical objects been imaged or at least directionally resolved from the ISS?
The ISS has an X-ray telescope called NICER and this answer in Astronomy SE (and links therein) explain that it was able to show that there are hot spots clustered near one pole of the pulsar PSR ...
Is NICER/SEXTANT the first civilian "spacecraft" to determine it's own position in space without GPS or uplinked data?
Computers on board spacecraft can determine their positions using a combination of uplinked data from the ground and for those closer to Earth, GPS/GNSS. (See this answer and this question for ...
What is the story behind NICER's mission patch?
The upcoming SpaceX launch with the apparently first re-use of a dragon capsule will bring with it the NICER array. NICER is a directional X-ray spectrometer with very precise timing capability. It ...
How will NavCube (actually) be important for the XCOM testing and demonstration?
According to the NASA news article NASA’s NavCube Could Support an X-ray Communications Demonstration in Space — A NASA First: The new technology, called NavCube, combines NASA’s SpaceCube, a ...
What will the X-ray communications (XCOM) transmitter look like?
The NASA news article NASA’s NavCube Could Support an X-ray Communications Demonstration in Space — A NASA First mentions the potential use of X-ray wavelengths for improved range of deep space ...
