Per Aspera Ad Astra (Russian: Через тернии к звёздам, USA screen name - Through the Thorns to the Stars;[a] Humanoid Woman) is a 1981 Soviet science fiction film directed by Richard Viktorov and based on a novel by Kir Bulychov.

A friend of Lebedev, Prof. Ivanova, begins studying Neeya's neurophysiology and finds a special neurocenter in her brain that can be triggered remotely.

Aboard was Professor Glan, who was building an army of clones and awaiting a signal from rebel forces on the planet that the time was right to return and take over.

After the humans successfully test a way to clean the air, he poisons the only remaining water supply and blames it on them, inciting a riot.

Near death, Rakan crawls off and releases Glan's last and most deadly experiment, a blob-like mass which begins killing everyone in the lab, including Turanchoks.

A heavily-edited English-dubbed version, and entitled Humanoid Woman was featured on an 11th episode of Mystery Science Theater 3000.
