Use the language · 1/2What does “common fuel supply” mean?

Read the answer and explanation

One supply used by both propulsion types. The first paragraph combines two propulsion types from a common supply.

Clue: NASA’s 25 September account described completed ground tests of ASCENT, a small satellite combining chemical and electric propulsion from a common fuel supply.

Use the language · 2/2What does “subsequently reported launch” establish?

Read the answer and explanation

The launch report followed the ground-test account.. The final paragraph identifies a later development.

Clue: NASA subsequently reported launch on 1 October. This later development updates the September account, while remaining distinct from successful completion of the planned in-space demonstration.

Grammar in this story: Distinct from + noun phrase

remaining distinct from successful completion

“Distinct from” means separate from, preserving the difference between launch and successful demonstration.

Your turn

Explain why adding the October launch update should not erase the September account’s original scope.

See one possible answer

The September account described ground readiness tests. The later launch is useful additional information, but it was a different milestone and still did not establish successful completion of the in-space demonstration.

Your answer can be different. Give a reason and use your own words.
