NASA is a CIA Manager, based on an heavy modified version of latest source of Big Red Menu, which is compatible with ANY firmware >= 4.1.
It uses libSu/libsvchax to get access to required services for LEGIT CIAs installation on fw >= 9.3 and libkhax to get access to required services for ANY CIAs installation on fw 4.1 - 9.2.
It also have network installation feature which doesn't need double free space cause it will perform a full network installation.

NASA GUI CUSTOMIZATION
Starting from NASA v.1.6, it's possible to use themes to customize your NASA installation. What you have to do is to place a file named as nasa_theme.lua in the root of your SD with some info inside it. You can find a simple sample theme in the RAR archive of NASA. Just open the lua file with a text editor and personalize it to make your own theme!
HOW TO USE BUILT-IN FTP SERVER
Starting from NASA v.1.6, it's possible to connect to NASA through a generic FTP client. This will allows you possibility to UNINSTALL installed titles from both NAND and SDMC and also install CIA files to NAND/SDMC. Using an ftp client will have a lot of advantages like timeout resolving, native multichain installation support, real-time progressbar (at least on Filezilla) and so on.
This is a little video showing this feature when it was under development:
HOW TO USE NETWORK INSTALLATION (HOUSTON)
To use network installation feature, you need to start NASA and check the IP showed on top screen.
Then you can open a terminal (Linux/Mac) / command-line prompt (Windows) and launch houston with the IP showed on 3DS (without the part after ":") and the CIA filename as arguments. Example:
[code]houston 192.168.1.60 file.cia[/code]
Q) Free Space reported by NASA is wrong and i can't install a CIA file, what can i do?
A) Disable Security Mode.
Q) Can i install any CIA file on fw >= 9.3?
A) No, you can install only LEGIT cias, here you can find a list of available ones with MD5, SHA1 and CRC hashes ( https://gbatemp.net/threads/how-to-inst ... st-5921202 ).
Q) What's the best way to boot it on fw >= 9.3?
A) I suggest you to use MenuHax as entrypoint with WiFi ENABLED when you launch NASA (NOTE: If you start NASA with Wifi DISABLED on fw >= 9.3, you'll not be able to use Network Installer).
Q) When i use Houston, it asks for a cygwin1.dll file. Where i can find it?
A) https://github.com/Rinnegatamante/lpp-3 ... ygwin1.dll
Q) Is it possible to chain install CIA files with Houston?
A) Yes, i suggest you to use this GUI by Baoulettes : https://gbatemp.net/threads/release-nas ... st-6001029
