50 Years Ago: Mariner II at Venus
Mariner Space Probe illustration.
On this last day of 2012, I'm trying to catch up on some 50 years ago
items from 1962. On december 14, 1962, the Mariner 2 space probe made
its closest pass to the planet Venus. Closing to about 41,000 km, the
encounter was also the first time a planetary probe had reached another
planet. Mariner 2 had had several problems along the way, but the
durability of the craft came through and gave the world new information
about our sister planet.
The data radioed back from Mariner confirmed scientists' estimates of
the incredibly hot temperatures and the thick atmosphere of the planet.
It also determined that the temperature was fairly evenly distributed
around the entire globe. Experiments searching for a magnetic field came
up empty, meaning Venus either had a very tiny magnetic field or there
wasn't one. Other interesting discoveries showed that Venus had a slow
rotation that was in the opposite direction from that of Earth's and
that there was no radiation belt like our own Van Allen Belt.
Mariner 2 continued on past Venus into an orbit around the Sun. It was
last heard from on January 3, 1963, and is still out there today....

Things I Found Interesting
- Beyond a few brief trips to the Moon over four decades ago, humanity has never ventured outside of Earth's protective magnetic field. And while it's natural to dream of exploring the stars, such voyages may carry impossibly high medical risks. Read On
- If the sun looks a little larger than usual today, you're not seeing things. Today (Jan. 2) marks the time when the Earth is at perihelion, the point in its orbit at which it is closest to the sun. Read On

This question is a little off-topic from this post, but have we received any word about the date when the center will reopen? We heard January, and it's January.
