Can someone let me know if the following is a run-on sentence or acceptable?
1st version:

2nd version:
This probe had to be specially designed by NASA because it has to endure various temperatures of space. Although it has a 10 year main voyage, the electrical components are only going to be used for 2 years.

The 1st version is a run-on sentence. Other notes: 10-year used for only 2 years (you may want to spell out two )
