Electronic voice alert (EVA) was an option available on many Chrysler K-car-based vehicles in the mid-1980s. [ 1 ] Chrysler and Dodge used technology of the Texas Instruments LPC Speech Chips , that were also used in the Speak & Spell toy.
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ...
View of Skylab from the Skylab 2 Command/Service Module during the final flyaround inspection. Two weeks later, Conrad and Kerwin performed a second EVA, freeing the stuck solar panel and increasing the electrical power to the workshop. They had prepared for this repair by practicing in the Neutral Buoyancy Simulator at the Marshall Space ...
The fairing externally contained a retractable forward-facing spotlight; an EVA floodlight to aid the command module pilot in SIM film retrieval; and a flashing rendezvous beacon visible from 54 nautical miles (100 km) away as a navigation aid for rendezvous with the LM.
This was the first EVA by a Command Module Pilot since Scott performed one on Apollo 9. As the crew began their preparations, they left the Lunar Sphere of Influence at 238 hours, 14 minutes, 51 seconds GET, at which point the gravitational pull of the Earth was stronger than that of the Moon.
Alfred Merrill Worden (February 7, 1932 – March 18, 2020) was an American test pilot, engineer and NASA astronaut who was command module pilot for the Apollo 15 lunar mission in 1971. One of 24 people to have flown to the Moon, he orbited it 74 times in the command module (CM) Endeavour.
DOGE wants access to filers’ data, and the commerce secretary says Trump wants to scrap the IRS. But filing a return remains mandatory — the earlier the better, tax advisers say.
NASA considered the flight EVA to be a total success, and Aldrin again returned to McDonogh to perform a post-mission evaluation of the EVA. The post-mission evaluation verified the value of using neutral buoyancy simulation training before attempting all of the EVA tasks while wearing a pressure suit and working in the hostile environment of ...
