An orbit near the craft's planned orbit was established, and the mission continued despite the abort to a lower orbit. [7] [8] The Mission Control Center at Johnson Space Center observed an SSME failure and called "Challenger-Houston, abort ATO." The engine failure was later determined to be an inadvertent engine shutdown caused by faulty ...
NASA and Boeing have been monitoring two issues with the Starliner spacecraft: one with a set of thrusters and the other involving helium leaks in the propulsion system.
Abort to Orbit. Faulty temperature sensor incorrectly indicated that fuel turbine discharge temperature exceeded the limit. Therefore, one main engine was shut down at T+345 s, resulting in a much lower orbit than planned. All mission objectives achieved [62] [63] 20 27 August 1985 10:58:01 UTC 06:58:01 EDT STS-51-I: Discovery: 5 07d 02h LC-39A ...
This delay resulted in an abnormal orbit and excessive fuel use. The decision was made to scratch the ISS rendezvous/docking since the spacecraft burned too much fuel to reach orbit even after Mission control center fixed the MET clock issue. NASA and Boeing officials placed the spacecraft in a different orbit and the entire flight plan had to ...

The debris poses a substantial risk to low-Earth orbit constellations, particularly those orbiting below 800 kilometers, and may remain in orbit for years, increasing the likelihood of collisions. This incident highlights ongoing concerns about space debris and the increasing risk of a cascading effect as more objects are launched into orbit.
Lunar Orbiter 1 was injected into an elliptical near-equatorial lunar orbit 92.1 hours after launch. The initial orbit was 189.1 km × 1,866.8 km (117.5 mi × 1,160.0 mi) and had a period of 3 hours 37 minutes and an inclination of 12.2 degrees. [10] On August 21, perilune was dropped to 58 km (36 mi) and on August 25 to 40.5 km (25.2 mi). The ...
