Surveyor Uncrewed Spaceflight

Surveyor 3 lands on the moon

SurveyorNASA’s robotic explorer Surveyor 3 touches down safely on the moon, snapping pictures and – with an extendable scoop arm – gathering and analyzing samples of lunar soil. Its landing site, a lunar plain called the Ocean of Storms, becomes the site of a unique long-term experiment: in two years, Surveyor 3 will become the first (and, to date, only) unmanned spacecraft to be personally inspected by humans after its landing.

ESSA-5

ESSAThe recently-rechristened Environmental Sciences Service Administration launches, with the help of NASA, ESSA-5, the latest in a constellation of weather satellites operated by the former U.S. Weather Bureau. Though suffering from a few technical glitches and system failures, ESSA-5 remains in service until late 1968.

Crewed Spaceflight Soyuz

Soyuz 1

Vladimir KomarovThe first flight of the Soviet Union’s new manned space vehicle, Soyuz 1, lifts off from the Baikonur Cosmodrome. Though designed to accomodate a crew of three – and intended to be the answer to NASA’s Apollo command/service module in the ongoing race to reach the moon – the first Soyuz is flown by test pilot (and close friend of Yuri Gagarin) Vladimir Komarov. Though early plans for the mission involve a rendezvous and docking with a second Soyuz, only one vehicle is available for the mission, and it suffers a series of technical problems. Though aware of the faults in the Soyuz design, engineers have been pressured to put a manned Soyuz in orbit for political reasons.

Crewed Spaceflight Soyuz

Soyuz 1: cosmonaut down

Soyuz 1After a day in space aboard a spacecraft crawling with technical glitches, cosmonaut Vladimir Komarov orients the Soyuz 1 capsule for return to Earth. Though the vehicle survives reentry through Earth’s atmosphere, the main parachute fails to open, and the first Soyuz capsule returns to Earth at a speed of well over 100 miles per hour, killing Komarov instantly. The Soviet Union’s space program is stalled – much like the American Apollo program, postponed after the fatal Apollo 1 fire – well into 1968 as a result of the need to redesign Soyuz from the inside out.

Lunar Orbiter Uncrewed Spaceflight

Lunar Orbiter 4 launched

Lunar OrbiterNASA’s fourth Lunar Orbiter satellite lifts off for its one-week trek to the moon. Placed into an orbit that takes it over the moon’s poles instead of its equator, Lunar Orbiter 4 is able to map virtually all of the near side of the moon over a period of two weeks. Plans to have Lunar Orbiter 4 map the far side are thwarted by mechanical failures and problems with the probe’s camera optics.

Uncrewed Spaceflight Venera

Venera 4

Venera 1The Soviet Union launches Venera 4, a space probe dispatched to the planet Venus. Venera 4 is equipped with a landing probe which it deposits into the planet’s dense atmosphere in October, and the probe’s findings stun scientists on Earth who had long considered Venus a near-twin of Earth: the atmosphere is predominantly carbon dioxide, with minimal oxygen and a pressure nearly 100 times Earth’s atmospheric pressure at sea level. The temperature within the Venusian atmosphere is found to soar past 800 degrees Fahrenheit, presenting a challenge for designers of the next round of vehicles to visit the planet. The Venera 4 landing probe is not equipped with cameras, and contact is lost with it before contact is made with the ground.

Mariner 5 launched

Mariner 5A near-identical twin of NASA/JPL’s unmanned Mariner 4 Mars probe, Mariner 5 lifts off en route to the planet Venus. Though the space probe’s architecture is similar to that of Mariner 4, Mariner 5 is modified to include solar shades to keep parts of the spacecraft cool, a problem which doesn’t exist at Mars. Mariner 5 takes almost exactly four months to reach Venus.

Test No. 6

Test No. 6The People’s Republic of China conducts a nuclear weapons test under the nondescript code name Test No. 6, which is in fact China’s first thermonuclear (hydrogen) bomb test. Dropped by an aircraft, Test No. 6 has a yield of 3.3 megatons. For context, China had conducted its first nuclear test barely three years earlier.
