Although their satellites did not record the entire flight process of the other party, what is known is that the Xinghai first completed two to three hours of experiments in the atmosphere before setting off to climb the gravity well.

Can chemical fuels really achieve such a long endurance and specific impulse?

If it can be done, its importance and threat may not be weaker than electric propulsion.

Even, in a sense, he would prefer that the space shuttle use a pure electric propulsion system rather than a combination of chemical fuel and electric propulsion.

The latter means that their opponents have found a new, ultra-efficient, high-specific-impact chemical fuel.

And this can not only be used on space shuttles.

Shaking his head and throwing away the complicated thoughts in his mind, Bill Nelson looked at the photo of the space shuttle on the surveillance screen.

No matter what, at least after dawn today, they had a pretty good analysis result when they faced questions from many media reporters.

Incomplete electric propulsion. On the surface, conventional chemical fuel propulsion methods are far less scary and shocking than pure electric propulsion systems.

At least, they can do the former, although not as efficiently.

However, a sense of powerlessness slowly rose from the bottom of his heart, gradually filling his entire soul.

Their opponents have already achieved further results in the aerospace field, but as the world's largest aerospace power, they cannot even analyze the technology used by their opponents...
