The Apollo LM was developed with a self-landing capability in its software, though in practice the mission commander took over manual control at around 150 meters altitude in all the actual landings. It used a radar altimeter for real-time altitude determination, and was accurate to within about 2 meters at low altitude, which doesn't sound great, but the LM'...

Yes, it will and has worked. Astronaut Ricky Arnold demonstrates it on the ISS.

Here is a simplified flow diagram of MOXIE Oxygen production is calculated using the pressure, temperature, and flow sensors in the O2 output leg. The product gases are exhausted to the Martian atmosphere. References: System Modeling, Design, and Control of the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) and Implications for Atmospheric ...

I believe I have worked out my own question using http://www.dept.aoe.vt.edu/~cdhall/courses/aoe4140/attde.pdf This uses the TRIAD algorithim in order to determine a rotation matrix between the body and inertial frames by knowing two vectors in both frames. Usefully, it also weights one as being more accurate than the other which in this case is likely to be ...

With the following constraints, it should at least be theoretically possible: The rocket is rotationally symmetric around an axis. The rocket is spinning around some axis that is not the symmetry axis. The first should be known a-priori. If we can then find the spin axis, the centre of gravity should be at their intersection. Each individual accelerometer ...

Several NASA-related papers mention partial-pressure CO2 sensors in use. I found a quick mention in a Wiki page about SCUBA equipment (oxygen sensing in their case) which says This type of sensor operates by measuring the voltage generated by a small electro-galvanic fuel cell. edit Per JRE's comment - the voltage here is generated by the chemical ...

The Apollo Guidance Computer used a plus/minus sign and 5 decimal digits. This can be seen in the "List of Nouns Used in Program Colossus" of the AGC manual as well as the number of digits on the DSKY user interface: There are various data types used by the nouns. A table in the source file PINBALL_NOUN_TABLES.agc controls how each noun is ...

Of course it depends on which biosignatures you are looking for. Microorganisms? Mammalians? Dinosaurs? Humans? Currently your generic question can only have one generic answer: yes, if big enough. Example of "biosignature": Please quantify your "enough".

The video look and feel makes me think it was generated by AGI, so you could easily mail support@agi.com The short answer, is that you cannot do it just out of the box. You have to generate pointing data external to STK and feed it in as a .sp file. The external data file could be generated with Matlab, python, or any other tool of your choice. AGI has a ...
