Passage Summary: Big space missions have been failing and wasting a lot of money lately, so we should stop doing them and try doing many smaller missions instead.

Conclusion: Grand space projects should be replaced by a series of smaller-scale projects.

Reasoning: Large-scale space initiatives have recently experienced several failures and significant financial losses.

Analysis: The argument relies on the assumption that smaller projects will not suffer from the same financial and technical pitfalls that plagued the larger ones. To strengthen this claim, we need to find evidence that small projects are inherently more stable or that their failures are less catastrophic. Look for an answer choice that highlights a specific advantage of small projects, such as lower risk or greater cost-efficiency, that large projects lack.
