Continuing experimental photography from captured German V2 rockets, scientists and engineers at the U.S. Army’s White Sands Missile Range capture a view of Earth from space at an altitude of 100 miles. Though the V2 is capable only of ballistic suborbital flight, an automated camera on the rocket captures the curve of the Earth before falling back to the surface. As with earlier experimental unmanned flights in 1946, also using captured V2 rockets, the rocket and camera are destroyed upon impact with the ground.

NASA Administrator James Fletcher announces that the ambitious twin Mariner Jupiter/Saturn ’77 space probes, due to be launched later in the year, have been christened with new names: Voyager 1 and Voyager 2. The name change has been initiated by recently-promoted Voyager program manager John Casani, who thinks the spacecraft need a name that’s less of a mouthful (the name “Discoverer” was also considered). For the first time, NASA openly admits that one of the vehicles – Voyager 2 – may continue on to Uranus and Neptune should its Saturn flyby go well in 1981, depending on the spacecraft’s health.

With nearly all of its members voting in favor of a work stoppage, unionized Hollywood writers go on strike for five months, crippling the TV and movie industry. Several shows’ fall premieres are delayed significantly, and many television series and movies have to commence production on partially-finished scripts with no opportunities for rewrites (including Tim Burton’s Batman and the James Bond movie Licence To Kill). In the unusually long “off season,” attempts are made at reviving prime-time variety shows, and fledgeling network Fox rushes several “unscripted” series, including Cops and America’s Most Wanted, into production to fill the gap; these prove to be surprise hits, giving “reality” TV a permanent foothold on many network schedules. Many returning shows do not air new episodes until November or December, if they even generate new material before the end of 1988.

After decades of the tiny object being seen only as a point of light in even the best telescopic images, the Hubble Space Telescope makes the first survey of the surface of Pluto. Even without the distortion introduced by Earth’s atmosphere, Hubble’s best shots of Pluto are vague due to the distance from Earth to Pluto, but they mark the first time that even blurry surface detail has been seen. The new images help NASA gain support for a Pluto flyby mission in the 21st century, which will eventually be named New Horizons.
