The stalled plans for a U.S. space station evolved into the International Space Station and were formally initiated in 1983 by President Ronald Reagan, but the ISS suffered from long delays, design changes and cost over-runs [3] and forced the service life of the Space Shuttle to be extended several times until 2011 when it was finally retired ...
Plot of velocity parameters and times on the horizontal axis, versus position on the vertical axis, for an accelerated twin roundtrip to a destination with Δx AB =10c 2 /α ~10 light years away if α~9.8 m/s 2. From the frame of reference of those on the ship the acceleration will not change as the journey goes on.
The original intention was to compensate for this lower payload by lowering the per-launch costs and a high launch frequency. However, the actual costs of a Space Shuttle launch were higher than initially predicted, and the Space Shuttle did not fly the intended 24 missions per year as initially predicted by NASA.

Escape speed at a distance d from the center of a spherically symmetric primary body (such as a star or a planet) with mass M is given by the formula [2] [3] = = where: G is the universal gravitational constant (G ≈ 6.67 × 10 −11 m 3 ⋅kg −1 ⋅s −2 [4])
Concept for a Mars base, with ice home, pressurized rover, and Mars suits, 2016. The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration of Mars. [1] Long-term proposals have included sending settlers and terraforming the planet.
It’s one of NASA's most iconic images. Bruce McCandless II free-floating in space more than 320 feet away from the Challenger space shuttle.

The first ISS module was launched in 1998, with major components delivered by Proton and Soyuz rockets and the Space Shuttle. Long-term occupancy began on 2 November 2000, with the arrival of the Expedition 1 crew. Since then, the ISS has remained continuously inhabited for 24 years and 92 days, the longest continuous human presence in space.
