Block 5 will consist of the new COPV 2.0 design for the helium bottle pressurization system. &nbsp;These systems will all fly on the first Block 5 mission next month that will loft the Bangabandhu-1

class=\"wp-caption-text\">The removal of the RSS at 39A<\/p>\n<p>While the RSS was vital for the Shuttle program, it is unnecessary for SpaceX\u2019s use of the pad, and demolition of the structure was preferred over the cost of maintaining the massive hunk of steel in a salt air environment by the Atlantic Ocean.<\/p>\n<p>Once the RSS is completely removed, pad teams will begin work to raise the slide wire basket escape system from the 195 ft level of the Fixed Service Structure (FSS) tower to the top of the FSS. &nbsp;The slide wire basket system was installed at pad 39A at the beginning of the Space Shuttle program for emergency use by final launch preparation teams and\/or flight crews in the event that the need to quickly evacuate pad arose.<\/p>\n<p>The same system will be utilized on Pad-A for SpaceX\u2019s crewed missions of the Falcon 9, but as the Falcon 9 places the Dragon capsule far higher than the Shuttle\u2019s crew cabin in terms of location along the FSS, the baskets must now be moved to the top of the tower. &nbsp;When asked by NASASpaceflight\u2019s Chris Gebhardt when that operation would begin, NASA said they were uncertain but expected the process to commence within the next few months.<\/p>\n<p>Moving the slide wire baskets is not the only addition to the FSS needed for SpaceX\u2019s crewed missions. &nbsp;Installation of the crew access arm must also take place before the crewed DM-2 flight later this year.&nbsp;&nbsp;Current schedules presented to the NASA Advisory Council late last month show that installation of the crew access arm at
