Answer: This story created tension because according to the text, there was a problem with the side jets.
Greg was trying to get to Mars for his brother, who was working at a bacteria laboratory, which can be proved according to the text when it says, " He had worked too hard and waited too long for this moment."
He had worked so hard that he wouldn't hesitate for anything, which can be found in the text when it states, "Fleetingly, he thought of Tom ... poor old stick-in-the-mud Tom, working away in his grubby little Mars-bound laboratory, watching bacteria grow." It seemed like Tom wasn't doing anything meaningful as a job, which caused Greg to feel a surge of pity for his brother. This can also be found in the passage when it states, "It was only one experiment, one tiny step in the work that could someday give men the stars, but to Gregory Hunter at this moment it was everything."
The fight might've only been a experiment that one day could allow men to touch the stars, but the evidence shown above proves that even small exerpiments might not be so small to some people after all.
