Your NASA sixty-second space shuttle update.

First of several updates on preparations for Hubble Servicing Mission 4 taking place at NASA’s Goddard Space Flight Center and Johnson Space Center.

Astronauts travel to NASA's Goddard Space Flight Center to prepare for Servicing Mission 4 to the Hubble Space Telescope. HST Servicing Mission Commander Scott Altman describes coming to Goddard and working with the flight hardware.

A team at NASA's Goddard Space Flight Center designs and builds the special tools and aids astronauts need when they service the Hubble Space Telescope. Engineers describe working with the astronaut crew and developing tools to meet specific challenges as well as inventing new tools that will help NASA astronauts well into the future.

In planning for Servicing Mission 4 to Hubble, crew members divide their time between NASA’s Johnson Space Center, Houston, working underwater on a Hubble mock-up to simulate the effects of weightlessness, and NASA’s Goddard Space Flight Center, Greenbelt, Md., where they practice scheduled mission tasks on a Hubble mock-up inside a large clean room facility.

The Hubble would not be able to do what it does without the help of a small group of dedicated engineers and technicians at NASA’s Goddard Space Flight Center. During HST Servicing Missions the Space Telescope Operations Control Room at NASA Goddard Space Flight Center becomes a very busy place.

The Cosmic Origins Spectrograph (COS) will significantly enhance the spectroscopic capabilities of HST at ultraviolet wavelengths, and will provide observers with unparalleled opportunities for observing faint sources of ultraviolet light.

Plankton is among the most important marine life forms, but excessive blooms can lead to phenomena known as dead zones, where water at the bottom of the ocean becomes depleted of oxygen and proves lethal for marine organisms. This short video explores this unique phenomenon, and examines how human activity in summer months can contribute to plankton blooms that cause dead zones.
