U.S. Coast Guard Cutter Healy in the Beaufort Sea

Scientists on board the U.S. Coast Guard Cutter Healy in the Beaufort Sea, northeast of Barrow, Alaska, finished collecting the mission¹s sea ice data and cruised south on July 20, 2011, through thin ice and ultimately into the open ocean. The ICESCAPE mission, or "Impacts of Climate on Ecosystems and Chemistry of the Arctic Pacific Environment," is a NASA shipborne investigation to study how changing conditions in the Arctic affect the ocean's chemistry and ecosystems. The bulk of the research took place in the Beaufort and Chukchi seas in summer 2010 and 2011.

Tools being considered for use in freeing solar array wing of Skylab

S73-27403 (June 1973) --- Engineers at the NASA Marshall Space Flight Center examine tools that are being considered for use in freeing the solar array wing of Skylab. The device at center is a cable cutter which is operated by cable. Enhanced television pictures indicate that the wing is being held to the side of the Skylab by a strip of metal from the meteoroid shield. The cable cutter shown here clipped an identical strip of metal in a test at the Marshall Center, requiring 90 pounds of force. The cutter is one of several heads which could be attached to extension rods. Identical tools and rods were carried into orbit by the Skylab 2 crew. At right is the handle end of a rod. White material taped just below the handle is buoyancy packing to make the object weightless when submerged in water. The tools are being tested in underwater EVA tasks in the MSFC Neutral Buoyancy Simulator. Small object at left is the attachment head for a two-prong "rake" device for use on the end of a pole made up of one, two or more five-foot sections of extension rods. Photo credit: NASA

Around Marshall

A metal strap became tangled over one of the folded solar array panels when Skylab lost its micro meteoroid shield during its launch. Cutters like the ones used to free the solar array were used to cut the ribbon opening to the public a new full-scale Skylab cluster exhibit at the Alabama Space and Rocket Center in Huntsville, Alabama. Wielding the cutters are (left to right): Alabama Senator James B. Allen; Marshall Space Flight Center director, Dr. William R. Lucas, Huntsville Mayor, Joe Davis; Madison County Commission Chairman, James Record (standing behind Mayor Davis); and chairman of the Alabama Space Science Exhibit Commission, Jack Giles. Astronauts Conrad and Kerwin used the same type of tool in Earth orbit to cut the aluminum strap which jammed the Skylab solar array.

KENNEDY SPACE CENTER, FLA. -- At Astrotech Space Operations in Titusville, Fla., a worker installs bolt cutters on one of the THEMIS probes. The cutters will separate each probe from the payload carrier. The probes will undergo weeks of testing and launch preparations. This includes a functional performance test to verify the state of health of each of the five probes and pressurization and leak checks of the reaction control systems. THEMIS consists of five identical probes, the largest number of scientific satellites ever launched into orbit aboard a single rocket. This unique constellation of satellites will resolve the tantalizing mystery of what causes the spectacular sudden brightening of the aurora borealis and aurora australis - the fiery skies over the Earth's northern and southern polar regions. These lights are the visible manifestations of invisible energy releases, called geomagnetic substorms, in near-Earth space. THEMIS will not only seek to answer where and when substorms start, but will also provide clues as to how and why these space storms create havoc on satellites, terrestrial power grids, and communication systems. THEMIS is scheduled to launch Feb. 15 from Cape Canaveral Air Force Station. Photo credit: NASA/Jack Pfaller

KSC-2009-3030

CAPE CANAVERAL, Fla. – The tools that will be used to service NASA's Hubble Space Telescope on the STS-125 mission are displayed in the NASA News Center at NASA's Kennedy Space Center in Florida. Being held in the foreground is the grid cutter tool, which will enable removal of the Electromagnetic Interference Grid from the Advanced Camera for Surveys access cover. On space shuttle Atlantis’ STS-125 mission, Hubble will be serviced for the fifth and final time. The flight will include five spacewalks during which astronauts will refurbish and upgrade the telescope with these state-of-the-art science instruments. As a result, Hubble's capabilities will be expanded and its operational lifespan extended through at least 2014. The payload includes a Wide Field Camera 3, fine guidance sensor and the Cosmic Origins Spectrograph. Launch is scheduled for 2:01 p.m. EDT May 11. Photo credit: NASA/Jack Pfaller
