Zond 7, a formal member of the Soviet Zond program and unmanned version of Soyuz 7K-L1 manned moon-flyby spacecraft, the only truly successful test of L1, was launched towards the Moon from a mother spacecraft (69-067B) on a mission of further studies of the Moon and circumlunar space, to obtain color photography of Earth and the Moon from varying distances, and to flight test the spacecraft systems. Earth photos were obtained on August 9, 1969. On August 11, 1969, the spacecraft flew past the Moon at a distance of 1984.6 km and conducted two picture taking sessions. Zond 7 reentered Earth's atmosphere on August 14, 1969, and achieved a soft landing in a preset region south of Kustanai, Kazakhstan.
Like other Zond circumlunar craft, Zond 7 used a relatively uncommon technique called skip reentry to shed velocity upon returning to Earth. Of all circumlunar Zond craft launches, Zond 7 would have been the first to make a safe flight for a crew had it been manned. The return capsule is on display at Orevo, Russia.

Zond 2
Zond 2 was a 1964 space probe, a member of the Soviet Zond program, and was the fifth Soviet spacecraft to attempt a flyby of Mars. (See Exploration of Mars)
Zond-2 carried a phototelevision camera of the same type later used to photograph the Moon on Zond 3. The camera system also included two ultraviolet spectrometers. As on Mars 1, an infrared spectrometer was installed to search for signs of methane on Mars.
Zond 2 also carried six PPTs that served as actuators of the altitude control system. They were the first PPTs used on a spacecraft. The PPT propulsion system was tested during 70 minutes.
Zond 2, a Mars 3MV-4A craft, was launched on November 30, 1964. During some maneuvering in early May 1965, communications were lost. Running on half power due to the loss of one of its solar panels, the spacecraft flew by Mars on August 6, 1965 at 5.62 km/s, 1,500 km away from the planet.

Zond 6
Zond 6, a formal member of the Soviet Zond program and unmanned version of Soyuz 7K-L1 manned moon-flyby spacecraft, was launched on a lunar flyby mission from a parent satellite (68-101B) in Earth parking orbit. The spacecraft, which carried scientific probes including cosmic ray and micrometeoroid detectors, photography equipment, and a biological payload, was a precursor to a manned circumlunar flight which the Soviets hoped could occur in December 1968, beating the American Apollo 8. However Zond 6 crashed due to a parachute failure.
Mission
Zond 6 was the official designation for Soyuz 7K-L1 s/n 12. It was supposed to photograph the moon in colour and black and white from 8000 km and 2600 km ranges, then return to Earth, landing at Tyuratam only 16 km from the launch pad. It had been a long and difficult road to develop the L1 guidance system, but it worked perfectly that time.
Zond 6 flew around the moon on 14 November 1968, at a minimum distance of 2420 km. Photographs of the lunar near side and far side were obtained with panchromatic film. Each photo was 5 by 7 in (130 by 180 mm). Some of the views allowed for stereo pictures. The photos were taken from distances of approximately 11,000 km and 3300 km. However, only one negative was recovered from the camera container.

Send It
by: Electric Light OrchestraThe sun still shines way up above
But it don't matter now because
The dream is gone
The dream is just a memory (oh, yeah)
If you see my dream, send it back home to me.
The stars still glow up in the night
But somehow, they don't seem so bright
The dream is gone
The dream is just a memory (oh, yeah)
If you see my dream, send it back home to me.
'Cos I've been waiting for a long, long time
Thought I'd found a way
Now I just wait for someone to call
I'm waiting for it every day.
CHORUS:
Send it -- on the wires
Send it -- on a plane
Send it -- on an express
But send it back to me again.
The music plays so loud and clear
But somehow I can't make you hear
The dream is gone
The dream is just a memory (oh, yeah)
If you see my dream, send it back home to me.
When you get what you want, it's a long way down
And you can see for miles around
When you lose it, nothing is for real
If you see my dream, send it back to me.
REPEAT CHORUS
REPEAT CHORUS
Send it (send it, send it)
Send it
Send it (send it, send it)
Send it on the wires (send it, send it)
Send it on a plane...
