After what felt like a pause in the Space Race, things have now het up, and I'm getting excited abouting being on the NASA beat again.  To wit, both superpowers seem on the cusp of making a giant leap forward in the exploration of the great black unknown.

Two for the Price of One

It has been nearly a year since the Mercury program wrapped up.  Since then, NASA has been feverishly working on its Apollo lunar program, comprising the Saturn rocket, the three seat Command/Service Module, and the two seat Lunar Excursion Module.  We finally got a peek at a full scale mock-up of the last, and it's unlike any spacecraft I've ever seen before.

Even while NASA is progressing with Apollo, the space agency has also been proceeding with its Gemini two-seat spacecraft.  Gemini is a sort of bridge to Apollo, a direct successor to Mercury that will allow astronauts to perfect the techniques of orbital rendezvous and docking.  It is also likely that the Air Force will use Gemini to build a staffed space station and perhaps for other military purposes.

On April 8, 1964, the first Gemini soared into orbit atop a modified Titan II ICBM.  There was no one on board, but the flight was still an important one.  Using missiles borrowed from the Air Force is always a dicey proposition — they aren't designed to carry people, after all.  I am happy to report, however, that the new rocket did its job just about perfectly, delivering Gemini 1 to an orbit just slightly higher than planned.

The uncrewed spacecraft fell silent after its first orbit when the battery became exhausted, a planned occurrence.  In fact, no plans were ever made for recovery; the Titan second stage was left attached to the spacecraft, and holes were drilled into Gemini's heat shield to ensure it completely burns up when its orbit decays about two days from now.

This launch marks an important first step for Gemini.  The Titan II, a much simpler and stronger rocket than Mercury's Atlas, is now "man-rated."  It only remains for the capsule itself, to get the same certification.  That should happen with the Gemini 2 mission, planned for late this year. 

In any event, it's another "first" for America — we got the first two-seat ship into orbit!

Destination Unknown

The Soviet Union beat us to the moon in 1958 with Mechta, and they almost beat us to Mars last year, too (their craft went silent along the way).  Now, it looks like they're setting the stage for another deep space endeavor.

On April 2, 1964, the Russkies launched Zond 1 "for the purpose of developing a space system for distant interplanetary flights."  It left orbit, and TASS continues to report that Zond is functioning properly.  However, they are being extremely cagey about where the spacecraft is going.  Experts suggest that it might be a Venus probe based on its launch date and trajectory.  I suppose it could also be a long range mission with no planetary target like Pioneer 5 was.

Two days later, on April 4, the Soviets launched Kosmos 28, an orbital satellite "intended for the further exploration of outer space in accordance with the program announced by TASS March 16, 1962." 

Which is to say, probably a spy satellite like our own Discoverer program.

The Balloon Goes Down

Yesterday, we bade a fiery farewell to Explorer 9, the first of six planned 12-foot balloon satellites whose task is to measure the density of the top of Earth's atmosphere.  The satellite confirmed the daily bulge in the upper atmosphere caused by the sun's heating the air during the day, and it also verified the model of the region's temperature, established by prior satellites. 

Moreover, the satellite lasted long enough that its data could be compared to that of its identical successor, Explorer 19, which is still up there.

Explorer 9 was the first satellite to be launched by the Scout solid-fuel rocket and the first to be launched into orbit from Wallops Island in Virginia.  Ya did good, pal!
