MEDIA ADVISORY 16-042 John Grunsfeld Announces Retirement from NASA

John Grunsfeld will retire from NASA April 30, capping nearly four decades of science and exploration with the agency. His tenure includes serving as astronaut, chief scientist, and head of NASA’s Earth and space science activities.

Grunsfeld has directed NASA’s Science Mission Directorate as associate administrator since 2012, managing more than 100 science missions -- many of which have produced groundbreaking science, findings and discoveries.

“John leaves an extraordinary legacy of success that will forever remain a part of our nation’s historic science and exploration achievements," said NASA Administrator Charlie Bolden. “Widely known as the ‘Hubble Repairman,’ it was an honor to serve with him in the astronaut corps and watch him lead NASA's science portfolio during a time of remarkable discovery. These are discoveries that have rewritten science textbooks and inspired the next generation of space explorers."

Geoff Yoder, currently the directorate’s deputy, will serve as acting associate administrator until a successor is named.

“After exploring strange new worlds and seeking out new life in the universe, I can now boldly go where I’ve rarely gone before – home,” said Grunsfeld. “I’m grateful to have had this extraordinary opportunity to lead NASA science, and know that the agency is well-positioned to make the next giant leaps in exploration and discovery.”

Notable science achievements under Grunsfeld’s leadership include the Curiosity rover Mars landing in 2012 – and its remarkable discoveries about the habitability of ancient Mars – and the July 2015 New Horizons Pluto flyby, completing the initial reconnaissance of the solar system.

Grunsfeld managed numerous missions to protect and study our home planet, including the Deep Space Climate Observatory, Orbiting Carbon Observatory-2, and Global Precipitation Measurement spacecraft, in addition to numerous Earth science aircraft campaigns. These and other projects have laid the foundation for future missions to better understand how Earth is changing.

Grunsfeld has also been a strong advocate for research with suborbital rockets, high-altitude balloon flights and CubeSats, to enable great science and train the next generation of explorers.

Preparations are well underway for a host of other missions and activities that will continue Grunsfeld’s work. These include the first U.S. mission to return a sample of an asteroid, the first mission to look for signs of life on Jupiter’s moon Europa, a mission to study the sun closer than ever before, participating in a national space weather strategy, and constructing the next rover to Mars, scheduled to launch in 2020.

Additionally, NASA’s fleet of robotic spacecraft are exploring the solar system and beyond, revealing the workings and beauty of the universe, while discovering thousands of new worlds. This pioneering work will continue with the launch of the James Webb Space Telescope in 2018, and the Wide-Field Infrared Survey Telescope.

Grunsfeld, a fierce proponent of science education and five-time space shuttle astronaut, was the lead spacewalker during the last Hubble Space Telescope servicing flight in 2009, which successfully upgraded the observatory to the apex of its scientific capability. He’s also the last human to touch the iconic telescope. In April 2015, Hubble celebrated 25 years of operations, vastly outperforming its planned lifetime of 15 years. In 2015, Grunsfeld was inducted into the U.S. Astronaut Hall of Fame.

MEDIA ADVISORY M16-035 NASA Progresses Toward SpaceX Resupply Mission to Space Station

NASA provider SpaceX is scheduled to launch its eighth Commercial Resupply Services mission to the International Space Station on Friday, April 8. NASA Television coverage of the launch begins at 3:30 p.m. EDT.

The SpaceX Dragon spacecraft is targeted to lift off on the company's Falcon 9 rocket at 4:43 p.m. from Space Launch Complex 40 at Cape Canaveral Air Force Station (CCAFS) in Florida, carrying science research, crew supplies and hardware to the orbiting laboratory in support of the Expedition 47 and 48 crews.

NASA TV also will air two briefings on Thursday, April 7. At 1 p.m., scientists and researchers will discuss some of the investigations to be delivered to the station, followed by a briefing by mission managers at 3:30 p.m. The briefings also will stream live on the agency’s website.

About 10 minutes after launch, Dragon will reach its preliminary orbit, deploy its solar arrays and begin a carefully choreographed series of thruster firings to reach the space station.

The spacecraft will arrive at the station Sunday, April 10, at which time NASA astronaut Jeff Williams and ESA (European Space Agency) astronaut Tim Peake will use the station’s robotic arm to capture the Dragon spacecraft. Ground commands will be sent from Houston to the station’s arm to install Dragon on the bottom side of the Harmony module for its stay at the space station. Live coverage of the rendezvous and capture will begin at 5:30 a.m. on NASA TV, with installation set to begin at 9:30 a.m.

The following day, the crew will pressurize the space between the station and Dragon and open the hatch between the two spacecraft.

The Dragon spacecraft will deliver almost 7,000 pounds of supplies and vehicle hardware to the orbital outpost and its crew. The cargo includes the Bigelow Expandable Activity Module (BEAM), which will be attached to the space station to test the use of an expandable space habitat in microgravity. Scheduled to return to Earth in May, the Dragon spacecraft will bring back biological samples from astronauts, including those collected during NASA’s one-year mission.

The new experiments arriving to the station will help investigators study muscle atrophy and bone loss in space, use microgravity to seek insight into the interactions of particle flows at the nanoscale level and use protein crystal growth in microgravity to help in the design of new drugs to fight disease.

Dragon is scheduled to return to Earth on May 11. About five-and-a-half hours after it leaves the station, it will splash down in the Pacific Ocean off the coast of Baja California.

Media at the agency’s Kennedy Space Center in Florida will have the opportunity to participate in special tours and briefings on April 7 and 8, as well as view the launch. The deadline for media to apply for accreditation for this launch has passed. For more information about media accreditation, contact Jennifer Horner at 321-867-6598 or jennifer.p.horner@nasa.gov.

If the launch does not occur on Friday, April 8, the next launch opportunity is 4:20 p.m. Saturday, April 9, with NASA TV coverage starting at 3:15 p.m.

Micro-10:

The Micro-10 investigation studies how the stress of microgravity triggers changes in growth, gene expression, physical responses, and metabolism of a fungus called Aspergillus nidulans (A. nidulans), an important biomedical research species. Results provide new data on how spaceflight affects fungi, including whether the fungi can be induced to make new molecular compounds that could be used for development of new drugs. The experiment is managed and supported by Ames, and the principal investigator is Cheryl Nickerson of Arizona State University in Tempe, Arizona.

Micro-9:

Micro-9 examines how spaceflight and microgravity affect the mechanisms of cell biology. The study will use multiple genetic strains of the yeast model organism Saccharomyces cerevisiae (sack-ah-row-my-sees sara-vis-ee-ee) to enhance our understanding of how life responds to physical phenomena and physical forces. The study investigates specific mechanisms of yeast cell signaling and response to microgravity. This experiment is managed and supported by Ames and the principal investigator is Timothy G. Hammond, Institute for Medical Research, Inc., Durham Veterans Affairs Medical Center, Durham, North Carolina.


Microbial Tracking 1C:

Formerly known as Microbial Observatory-1, this experiment is a three-part investigation that seeks to characterize airborne and surface-associated populations of microorganisms aboard the International Space Station and will be conducted over three different SpaceX commercial cargo resupply missions, spanning months. Observations from the Microbial Tracking-1 study will provide NASA with information to estimate crew health and spacecraft performance risks stemming from microbial growth onboard a crewed space vehicle. Ames is the payload developer and implementer for the Microbial Tracking-1, and Ames also manages the Microbial Tracking-1 investigation. Kasthuri Venkateswaran of NASA’s Jet Propulsion Laboratory in Pasadena is the principal investigator for the investigation.
