Endeavour OV was built to replace Challenger using structural spare parts originally intended for the other orbiters and delivered in May ; it was first launched a year later.
After the loss of Challenger, NASA grounded the shuttle program for over two years, making numerous safety changes recommended by the Rogers Commission Reportwhich included a redesign of the SRB joint that failed in the Challenger accident. Other safety changes included a new escape system for use when the orbiter was in controlled flight, improved landing gear tires and brakes, and the reintroduction of pressure suits for shuttle astronauts these had been discontinued after STS-4 ; astronauts wore only coveralls and oxygen helmets from that point on until the Challenger accident.
The accidents did not just affect the technical design of the orbiter, but also NASA. This could be a new design eliminating the joint or a redesign of the current joint and seal.

NASA should encourage the transition of qualified astronauts into agency management Positions. The tire, brake and nosewheel system must be improved. Recommendation VII — Make all efforts to provide a crew escape system for use during controlled gliding flight.
NASA must establish a flight rate that is consistent with its resources. Columbia [ edit ] The shuttle program operated accident-free for seventeen years after the Challenger disaster, until Columbia broke up on re-entrykilling all seven crew members, on February 1, The accident began when a piece of foam shed from the external tank struck the leading edge of the orbiter's left wing, puncturing one of the reinforced carbon-carbon RCC panels that covered the wing edge and protected it during re-entry.

As Columbia re-entered the atmosphere, hot gas penetrated the wing and destroyed it from the inside out, causing the orbiter to lose control and disintegrate. After the Columbia disaster, the International Space Station operated on a skeleton crew of two for more than two years and was serviced primarily by Russian spacecraft.
While the "Return to Flight" mission STS in was successful, a similar piece of foam from a different portion of the tank was shed.Space Shuttle Columbia Disaster Pt 2: Final descent - BBC

The Orion spacecraft was left virtually unchanged from its previous design. The Space Launch System will launch both Orion and other necessary hardware.
It is then planned to be upgraded in various ways to lift tonnes, and then, eventually, tonnes. The delay is longer than expected because the Ares I was cancelled inleaving little time before the STS retired for something new to be ready for flight. Congress was aware a spaceflight gap could occur and accelerated funding in and in preparation for the retirement of the Shuttle. The first Dragon resupply mission occurred in May
