What is the terminal velocity of a space capsule?

00237 slug/cu ft or 1.229 kg/cu m) on the surface of the Earth. For a rocket landing on Mars, the atmospheric density is quite low, and the terminal velocity correspondingly higher. But the weight on Mars is also lower than on Earth so the terminal velocity is not as high as predicted by the atmospheric effect alone.

Which thermal control method did the Apollo command module use during re entry?

NASA used the SM’s propulsion system to insert the spacecraft into a transearth injection (TEI), which means Apollo would be heading back to Earth in a trajectory that allowed for a controlled descent into the Pacific Ocean.

Why did the return capsule enter into the Earth’s atmosphere bottom first?

Soyuz 5 almost ended in disaster, when the reentry capsule entered the atmosphere nose first – attributed to a failure of the service module to separate similar to that on the Vostok 1 flight.

What is the escape velocity of the Apollo 11 astronauts?

Answer Wiki. Not quite, Apollo 11 achieved a record for the highest speed for any manned vehicle by reaching 24,791 mph, but this was on their return voyage and under the gravitational influence of the Earth. Escape velocity is around 25,000 MPH depending on where you launch on the planet (it varies slightly).

How many hours and minutes did Apollo 11 take to reach Earth?

PAO:This is Apollo Control at 189 hours, 28 minutes. Apollo 11 is 40,961 nautical miles [75,860 km] from the Earth, approaching at a velocity of 9,671 feet per second [2,948 m/s]. Mid-Course Correction number 7 has been cancelled, and as a result we will let the crew sleep until an elapsed time of 190 hours.

How are the parachutes deployed from the Apollo space missions?

If you’re asking about the deployment of the three main parachutes of C/M-ELS (Apollo Command Module Earth Landing System), then this is simple enough to answer, the pilot chutes are deployed at about 10,000 feet (3.05 km) by a barometric switch, pulling the three main parachutes from their containers.

What happened to the 7th course correction on Apollo 11?

Last updated 2017-02-10 [The crew of Apollo 11 waken about five hours before splashdown, to be told that the final Midcourse Correction in the Flight Plan, the seventh, is cancelled. They photograph the Earth as it expands rapidly in the windows of their spacecraft.
