One fuel supply, two kinds of propulsion

In this lesson: Identify the shared supply and separate ground tests from launch.

Read the story

NASA reported on 25 September that its ASCENT CubeSat had completed ground tests. One fuel supply feeds chemical and electric thrusters.

The tests checked the spacecraft before flight. They did not themselves show that the system had worked in orbit.

Later update: NASA reported the satellite’s launch on 1 October. Launch is another milestone, but is not the same as completing the planned propulsion demonstration.

Editorial correction, 26 October 2026: We corrected factual wording and chronology after checking the sources below. This is a retrospective archive review; the original publication date is retained.

Read and practise

1. What do the chemical and electric thrusters share?

   1. Two completely separate fuel systems
   2. One fuel supply
   3. Only an identical ground-test date

2. Which event did the later update report?

   1. Completion of every propulsion experiment
   2. Ground testing before any launch was announced
   3. Launch on 1 October

Your turn

Name the completed stages and the result not established by launch alone.
