"All right, at ease," ordered Connel. As the three boys relaxed, Connel stepped over to the astrogation board and snapped a switch. Immediately a solar chart filled the huge chart screen. It was a black-and-white view of the planet Venus.

"This is where we're going first," he said, placing a finger on a ball-shaped satellite in orbit around the misty planet. "This is the Venus space station. As you know, Venus has no natural satellite of its own, so we built one. We'll blast off from here and go directly to the space station where the Polaris will be fitted with hyperdrive for deep-space operations. While at the station you will acquaint yourselves with the operation of the new audio communications transmitter. When I'm satisfied that you can handle it under the prevailing conditions of an extended space flight, we'll blast off for a test of its range and performance."

Major Connel paused and faced the cadets squarely. Then he continued: "This is an important mission—one which I hope will enable the Solar Guard to establish the first base outside of our solar system. Our destination is Tara, in the star system of Alpha Centauri. Tara is a planet in a stage of development similar to that of Earth several million years ago. Its climate is tropical, and lush vegetation—jungles really—covers the land surface. Two great oceans separate the land masses. One is called Alpha, the other Omega. I was on the first expedition, when Tara was discovered, and have just returned from the second, during which we explored it and ran tests to learn if it could sustain human life. All tests show that Tara can be transformed into a paradise."

Connel paused, took a deep breath, and continued: "I shall expect more than just hard work from you. I want everything you have to offer. Not just good performance, but excellence! I will not tolerate anything less, and if I'm forced to resort to extreme disciplinary action to get what I demand, then you can expect to receive every demerit in the book!" He stepped closer to the three cadets. "Remember! Spacemen—or nothing! Now, stand by to blast off!"

Without a word, the three cadets hurried to their stations and began routine procedure to raise ship.

"All departments ready to blast off, Major Connel," reported Tom, saluting sharply.

"Very well, Corbett, proceed," said Connel.

Tom called into the intercom, "Stand by for blast-off!" He then opened the circuit to the teleceiver screen overhead and spoke to the spaceport control tower.

"Polaris to spaceport control. Request permission to blast off. Request orbit."

"Spaceport traffic to Polaris. Your orbit has been cleared 089—repeat 089—blast off in two minutes...."
