Apollo 4 was a test flight that did not have a crew. It launced November 9, 1967.
Apollo 4 was a test flight of the Saturn V/Apollo spacecraft. There was no crew.
The Apollo missions had different crew sizes, with the majority of missions having a crew of three astronauts. However, the first two Apollo missions (Apollo 7 and Apollo 9) were crewed by three astronauts, while Apollo 8 and Apollo 10 had crews of four. Apollo 11, which famously landed on the moon, had a crew of three.
The crew of Apollo 4 was made up of all Navy captains: Command Module Pilot Walter M. Schirra, Jr., Senior Pilot Donn F. Eisele, and Lunar Module Pilot R. Walter Cunningham. Apollo 4 was an unmanned mission that tested the Saturn V rocket and the spacecraft systems in Earth's orbit.
Yes, two of the Apollo 13 crew members flew on other missions. Jim Lovell later commanded Apollo 16, and Fred Haise flew on the Apollo 19 mission, which was ultimately canceled, but he also participated in the Space Shuttle program. Ken Mattingly, the third crew member, flew on Apollo 16 and later commanded the STS-4 Space Shuttle mission.
On 17 April 1970 at 12:07:44 p.m. Central Standard Time, the crew of Apollo 13 splashed down only 4 miles from the prime recovery ship.
The Apollo 13 splashed down in earth , in the Pacific on 17/4/1970.
Apollo's 2 and 3 were ultimately not assigned. Apollo's 4, 5, & 6 were unmanned flights. A detailed chronology of Apollo's 2-6 begins with Apollo Saturn 204. AS-204, the official designation for Apollo 1, was scheduled to launch Feb. 21 1967. The name "Apollo 1" was chosen by the crew (Grissom, White, & Chaffee). A second and a third manned Apollo crews were selected and had begun training as of Jan. 1967. If Apollo 1 had launched successfully, the second and third crews would likely carry the following designations: Apollo 2 - McDivitt, Scott, and Schweickart (who would later crew Apollo 9) and Apollo 3 - Borman, Collins, and Anders (this crew would become Apollo 8, with Lovell replacing Collins). Following the Apollo 1 fire, NASA retired the Apollo 1 designation to honor the crew. The subsequent investigation and spacecraft redesign delayed manned Apollo flights for 21 months. During this time NASA applied the "popular" designation sequence to three unmanned Apollo flights. Apollo 4 (launched 11/9/67) was 1st test of the Saturn V, Apollo 5 (launched 1/22/68) 1st test of the Lunar Module, and Apollo 6 (launched 4/4/68) 2nd test of the Saturn V. It is said that NASA applied the designation Apollo 2 and 3 retroactively to AS-202 and AS-203, two unmanned Apollo Saturn 1B test flights launched in 1966, but this was never official. Apollo 7, making up Apollo 1's backup crew of Schirra, Eisele, and Cunningham, became the first manned Apollo mission launching in Oct. 11, 1968.
The Apollo lunar module's name was Eagle. On July 20, 1969, the first lunar manned landing occurred in the Eagle and the crew returned back to Earth 4 days later.
Apollo 13 was a spaceflight that took place in 1970. It was the seventh crewed mission in the Apollo space program and was intended to land on the moon, but an oxygen tank explosion forced the crew to abort the mission.
The first three missions of the Apollo Program were unmanned test flights of Apollo hardware. These missions were officially named AS-201, AS-202, and AS-203. The first manned mission was named AS-204. However AS-204 met with disaster, when fire broke out during a routine ground test and all three crew members were killed. The widows of the three astronauts asked NASA to retire the mission naming convention in honor of their husbands. NASA agreed, and AS-204 was renamed Apollo 1. NASA then made the decision that further missions would begin with Apollo 4. It is my pure speculation that the names 2 and 3 were skipped in honor of the Apollo 1 crew. Since there were three astronauts killed, Apollos 1, 2, and 3 were retired in their memory. As such, the next flight was named Apollo 4, so there was no official Apollo 2.
Apollo 7 was the first manned mission. Apollos 4 and 6 were unmanned tests of the large Saturn V moon rocket. Apollo 5 was an unmanned test of the first Apollo Lunar Module on a smaller Saturn IB rocket; it carried no command and service module. Two unmanned tests of a smaller Saturn launch vehicle, the Saturn I, are sometimes known as Apollo 2 and 3. The name "Apollo 1" was given to the crew of Grissom, White and Chaffee for the flight that they never got to fly because of the launch pad fire that killed them in January 1967.
Apollo 6, launched on April 4, 1968, was an uncrewed test flight of the Saturn V rocket and did not have a crew on board. It was designed to test the spacecraft's systems and performance in a high-stress environment. The mission aimed to validate the capabilities of the Saturn V for future crewed Apollo missions to the Moon.
