Space shuttle Discovery's seven-member STS-131 crew will begin its day by unloading the last transfer items in the Leonardo Multi-Purpose Logistics Module and then closing the hatches between it and the Harmony node in preparation for its return to the shuttle's payload bay.

Overnight International Space Station and Space Shuttle mission managers agreed there is no need for a fourth spacewalk to replace the nitrogen tank assembly that has a jammed valve. Station ground teams have determined the station can operate for an extended period of time in the current configuration. The team is continuing to troubleshoot the stuck valve and is looking at options for future replacement of the nitrogen tank assembly should that be necessary.

After a morning off, Discovery astronauts got back to work moving equipment and supplies to and from the International Space Station and preparing for Tuesday's spacewalk, the third and last planned for their mission.

Mission Specialists Rick Mastracchio and Clayton Anderson configured their tools in the Quest airlock. After a review of spacewalk procedures with other crew members, they will again spend the night in the airlock, its pressure reduced to 10.2 psi. That campout is aimed at reducing the nitrogen in their blood to avoid decompression sickness.

The spacewalk, replanned after difficulties bolting down an ammonia coolant tank on Sunday caused some rescheduling, is to begin at 3:11 a.m. EDT Tuesday and last 6½ hours. Activities include finishing the complicated change out of the large ammonia tank assembly, retrieving micrometeoroid shields from outside the airlock and retrieving a light-weight adapter plate assembly.

1. Upcoming School Contact
An Amateur Radio on the International Space Station (ARISS) contact has been scheduled for Jessup Elementary School in Houston, Texas on Monday, April 19 at 18:43 UTC. This will be a telebridge connection through ground station WH6PN in Hawaii. The school has incorporated the ARISS activity into its curriculum, specifically focusing on science, math, and language arts instruction across the pre-kindergarten to fourth grade levels.
