Jo, to je právě zajímavé sledovat ten náhled na věc v průběhu času, jak se měnil v závislosti na kontextu okolního dění. To se netýká jen kosmonautiky, platí to obecně. Proto rád koukám do historie.

NASA faces challenges in ensuring next-generation spacesuits are available to meet the Agency’s current schedules for
the Artemis lunar landing mission in 2028 and prior to the ISS’s decommissioning in 2030. NASA’s original schedules to
demonstrate the lunar and microgravity spacesuits in 2025 and 2026, respectively, were overly optimistic and ultimately
proved unachievable, as evidenced by delays of at least a year and a half for both spacesuits. Based on our analysis, if
Axiom experiences design and testing delays in line with the historical average for recent space flight programs, the
Artemis and ISS demonstrations may not occur until 2031.
In our judgment, the original schedules for both xEVAS spacesuits were overly optimistic, a long-standing
issue across the Agency that we have previously reported on.
17 Specifically, we determined the initial
development schedules for both spacesuits—spanning 3.4 years for lunar suits and 3.8 years for
microgravity suits—were less than half of the 8.7 year-historical average of time it takes from contract
award to test flight for recent space flight programs.18 If Axiom experiences design and testing delays in
line with this historical average, the lunar and microgravity spacesuit demonstrations would not occur
until 2031.
19 This would result in little to no overlap with the remaining service life of the ISS and is
3 years after the planned Artemis lunar landing date. See Figure 5 for a comparison of the proposed
spacesuit schedules to recent major space flight programs at NASA.

Axiom Space chief executive Jonathan Cirtain said Tuesday that Axiom’s suit has logged more than 950 hours of crewed pressurized testing and should complete critical design review this year. Problems can always occur during hardware development programs, of course, but things appear to be on track.
