Four solid fuel retro rockets were to slow the first stage, but one malfunctioned shortly after ignition. The first stage impacted the ocean surface at T+718.95, 961.29 kilometers (597.32 miles) down range. (N. 25.8155, W. 71.3491)
If all goes according to plan, once it separates from the Starship spacecraft, the Super Heavy booster will steer itself into the arms of Mechazilla, a massive structure back at SpaceX’s launch site that the company hopes will catch rockets mid-air as they head in for landing. The tow...
While engineers were resolving the technical challenges of the joint mission, military and space officials got engaged into an already familiar and mostly pointless argument over the mission duration. The controversy would last for most of 1962. Korolev and Keldysh were insisting on a three-day fli...
During the last decade, much data have been obtained on the effects of weightlessness, both from the relatively short Space Shuttle flights and from the long-duration flights of the NASA/Mir Science Program. Although the evaluation of some of the data is still in progress, already there is a...
Following stage separation, Starship’s six Raptor engines all started successfully and powered the vehicle to its targeted orbit, becoming the first Starship to complete its full-duration ascent burn. SpaceX said it’s now reviewing the data collected from the latest test flight and is seeking ...
The Messerschmitt HWK R11-203 engines were improved continually, starting at 850 pounds of thrust and eventually delivering 3,400 pounds. Burn duration increased from 7.5 minutes to nearly 15 minutes in that time. The common Revi 16/B, reflector, noncomputing gun sight was used. ...

On February 24, 2011,Discoverylaunched its final mission and docked with the International Space Station. The crew consisted of six American astronauts, all of whom had been on prior spaceflights, including Commander Steven Lindsey. The crew joined the long-duration six person crew ofExpedition 26...
Free tumble tests are similar to free spin tests, except that the duration of free tumble tests is usually quite short. The reason is that a tumbling model creates net lift and will traverse the test section rapidly. When longer test time is desired, a “free-to-pitch” rig can be used...
Message Duration (sec)- This option adjusts the length of time that a message remains on- screen before it disappears. You may input desired values directly from the keyboard or modify them using the mouse wheel. The higher the value, the longer the message remains on-screen. Enabled- This...
