Engineers are waiting for 15 tons of cargo to be installed on Discovery's cargo bay so that they can run a test and see if the space shuttle is ready to launch on April 5.

It has been planned by Kennedy Space Center workers to launch pad 39A and provide the nearest international space station with food, equipment and science experiments. It has also been decided that the cargo will not be shifted until results from weekend test are reviewed in the mangers meeting on Tuesday.

The mangers are looking forward to proper working of regulators linked to steering jets in the orbiter's right engine pod.

Before giving the green light for it to fly, managers wanted to make sure that the regulators are not leaking and are in good shape because there was helium leakage last weekend due to a valve problem during propellant.

"The information will allow management to make a more informed decision about what they want to do and what their options are", said Allard Beutel, a KSC spokesman.

Next Friday, KSC plans to meet NASA Executives to set an official launch date.
