After a five-month design study focusing on alternatives to a winged (and manned) reusable first stage bosoter for the upcoming Space Shuttle, NASA settles on a configuration consisting of two solid rocket boosters strapped to the shuttle’s external fuel tank. Among the alternatives considered was the possibility of restarting production of the Saturn V rockets that launched Apollo and Skylab missions, with the shuttle and its fuel tank separating from the Saturn V’s first stage at high altitude (though in this configuration, a failure of the shuttle’s main engines would prove to be catastrophic). The SRB/tank configuration is expected to shave half a billion dollars off of the shuttle’s development costs.

NASA launches the Apollo 16 mission to the moon, lasting 11 days total. Astronauts John Young and Charlie Duke descend to the lunar surface in the lander Orion, while Ken Mattingly pilots the command/service module Casper in orbit. Again, a lunar rover is tucked into one side of the lunar module, allowing Young and Duke to reach distances of 16 miles from their landing site. They spend a total of 20 hours walking on the moon’s surface, collecting over 200 pounds of soil and rock samples from the Descartes highlands region.
Students and seasoned weather researchers at the National Severe Storms Laboratory in Norman, Oklahoma embark on the Tornado Intercept Project (TIP), a concerted effort to gather film footage of developing or active tornadoes in an effort to study wind and debris patterns. Though believed by some to be of limited scientific value, TIP is the beginning of “storm chasing” and yields major breakthroughs in scientific understanding of the formation of tornadoes just one year later.
ITV premieres the first episode of Escape Into Night, adapted by Ruth Boswell from the Catherine Storr novel Marianne Dreams. Though originally shown in color, the color master tapes are lost over time, and the series survives only in black & white recordings originally made to sell to foreign markets. It is these recordings that will eventually get a DVD release in the 21st century.

Having spent six years wrangling with various mission profiles for a “Grand Tour” of the outer solar system, made possible by a favorable planetary alignment occurring only once every 175 years, NASA finally authorizes a very stripped-down version of its original ambitious Grand Tour plans. The Mariner Jupiter/Saturn ’77 mission will consist of two twin unmanned spacecraft to be launched in
