Did Mariner 4 take pictures of Mars?
After an eight-month voyage to Mars, Mariner 4 makes the first flyby of the red planet, becoming the first spacecraft to take close-up photographs of another planet. The images show lunar-type impact craters, some of them touched with frost in the chill Martian evening.
How many pictures did Mariner 4 Take Mars?
22 photographs
On July 14, 1965, Mariner 4 passed within 6,118 miles of Mars, snapping 22 photographs of the planet and taking scientific measurements. The spacecraft passed behind the planet as seen from Earth, allowing a radio occultation study to estimate the density of the Martian atmosphere.
What was Mariner 4?
What was Mariner 4? One of the great early successes of the U.S. space program, the Mariner 4 mission flew by Mars on July 15, 1965, and took the first photos of another planet from deep space.
Where is Mariner 4 right now?
On December 21, 1967, communications with Mariner 4 were terminated. The spacecraft is now derelict in an exterior heliocentric orbit.
How long did it take Mariner 4 to get to Mars?
228 days
The first spacecraft ever to make the journey from Earth to Mars was NASA’s Mariner 4, which launched on November 28, 1964 and arrived at Mars July 14, 1965, successfully taking a series of 21 photographs. Mariner 4’s total flight time was 228 days.
How much did the Mariner 4 cost?
554 million USDMariner 4 / Cost
The total cost of the Mariner 4 mission is estimated at $83.2 million. Total research, development, launch, and support costs for the Mariner series of spacecraft (Mariners 1 through 10) was approximately $554 million.
Why was Mariner 4 Important?
Mariner 4 was the first spacecraft to fly by Mars, and the first to return close-up images of the Red Planet. Its blurry views of craters and bare ground led some scientists to think that Mars is similar to the moon. It squashed some views that Mars was a haven for life.
Did the Mariner 4 come back to Earth?
After the Mars flyby, Mariner 4 coasted into solar orbit. The spacecraft continued to return data to Earth for another three years, and was used by scientists to study the solar wind environment.

Why did Sojourner rover stop working?
After landing, the Pathfinder lander transmitted data for about 3 months and then shut down. This left the semi-autonomous rover Sojourner still functional but unable to communicate with Earth via the lander.
Was the Mariner 4 successful?
One of the great successes of the early American space program, the Mariner 4 mission journeyed to Mars — making its closest approach on July 15, 1965 — and took the first photos of another planet from space.
