This chart describes the Skylab student experiment Ultraviolet (UV) From Pulsars, proposed by Neal W. Sharnon of Atlanta, Georgia. This experiment was to observe several pulsars with Skylab's UV spectrometer to determine their intensities in that portion of their spectra. A more detailed description of a pulsar's electromagnetic emission profile would be expected to further define means by which its energy is released. Unfortunately, upon examination of the photographic plates containing the data from the experiment, it was found that an alignment error of the spectrometer prevented detection of any of the pulsars. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

Aerospace pioneers who worked on the launch of Explorer 1 participate in a panel discussion with NASA Kennedy Space Center Director Bob Cabana, at far left, at the center's Training Auditorium on Wednesday, May 9, 2018. Panelists, from left are William "Curly" Chandler, firing room engineer; Lionel (Ed) Fannin, mechanical and propulsion systems; Terry Greenfield, blockhouse engineer; Carl Jones, measuring branch engineer; and Ike Rigell, electrical networks systems chief. Explorer 1 was the first satellite launched by the U.S. It was launched by the Army Ballistic Missile Agency on Jan. 31, 1958 on a Juno I rocket from Launch Complex-26.

Baikonur Cosmodrome, Kazakhstan -- Cosmonaut Yuri I. Malenchenko (left), Expedition Seven commander, and astronaut Ed Lu have their Russian Sokol suits checked for leaks, as well as Soyuz inspection and seat liner check. Veteran Russian cosmonaut Yuri Malenchenko and veteran NASA astronaut Ed Lu have been named as the primary crew for the planned April 26, 2003, launch of a Russian Soyuz TMA-2 spacecraft to the International Space Station. Malenchenko and Lu will be called the Expedition 7 crew. Russian cosmonaut Alexander Kaleri and NASA astronaut Michael Foale are the backup crewmembers to Malenchenko and Lu. Expedition 6 Commander Ken Bowersox, Flight Engineer Nikolai Budarin and NASA Space Station Science Officer Don Pettit will return to Earth aboard the Soyuz TMA-1 craft in May 2003. The three Expedition 6 crewmembers were launched on Nov. 23, 2002. They have been aboard the Station since November 25. They were originally scheduled to return in March aboard the Space Shuttle Atlantis during the STS-114 mission. Malenchenko and Lu will continue to operate the science payloads already on board, as well as maintaining the Station. Photo Credit: NASA/Bill Ingalls

On Saturday, November 26, NASA is scheduled to launch the Mars Science Laboratory (MSL) mission featuring Curiosity, the largest and most advanced rover ever sent to the Red Planet. The Curiosity rover bristles with multiple cameras and instruments, including Goddard's Sample Analysis at Mars (SAM) instrument suite. By looking for evidence of water, carbon, and other important building blocks of life in the Martian soil and atmosphere, SAM will help discover whether Mars ever had the potential to support life. Curiosity will be delivered to Gale crater, a 96-mile-wide crater that contains a record of environmental changes in its sedimentary rock, in August 2012. ----- NASA image November 18, 2010 The Sample Analysis at Mars (SAM) instrument is considered one of the most complicated instruments ever to land on the surface of another planet. Equipped with a gas chromatograph, a quadruple mass spectrometer, and a tunable laser spectrometer, SAM will carry out the initial search for organic compounds when the Mars Science Laboratory (MSL) rover lands in 2012.
