NASA - National Aeronautics and Space AdministrationHouston, TX – Researchers may be “excyted” to learn that osteocyte cultures are headed to the International Space Station this spring for the first time. With their delivery on the next SpaceX commercial resupply services mission this month, the Osteocytes and mechano-transduction (Osteo-4) investigation team will analyze the effects of microgravity on this type of bone cell.

Understanding these effects will be critical as astronauts plan for future missions that require longer exposure to microgravity, such as to deep space or Mars.

NASA reports Alzheimer’s disease research to be conducted on International Space Station

 

Written by Rachel Molina
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Alzheimer’s disease is a global problem. In the United States alone, more than 5 million people have the disease and a new diagnosis is made every 67 seconds—numbers that are just a fraction of worldwide totals. Among medical researchers, Alzheimer’s is a top priority.

Researchers working with astronauts on the International Space Station are embarking on a mission to discover the origin of Alzheimer’s. Although the details are still a little fuzzy, researchers believe that Alzheimer’s and similar diseases advance when certain proteins in the brain assemble themselves into long fibers that accumulate and ultimately strangle nerve cells in the brain.

NASA to launch Expandable Habitat to International Space station

 

NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA and Bigelow Aerospace are preparing to launch an expandable habitat module to the International Space Station this year. The agency joined Bigelow Thursday at its Las Vegas facility to mark completion of the company’s major milestones.

The Bigelow Expandable Activity Module, or BEAM, leverages key innovations in lightweight and compact materials, departing from a traditional rigid metallic structure. In its packed configuration aboard SpaceX’s Dragon spacecraft launched on a Falcon 9 rocket, the module will measure approximately 8 feet in diameter.

NASA Astronauts to conduct Spacewalks to ready International Space Station for Commercial Transport Ships

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Change is on the horizon for the International Space Station as three upcoming spacewalks prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft.

The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.

NASA reports OPALS on International Space Station shows how Lasers can Speed Communications

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – You may know opals as fiery gemstones, but something special called OPALS is floating above us in space. On the International Space Station, the Optical Payload for Lasercomm Science (OPALS) is demonstrating how laser communications can speed up the flow of information between Earth and space, compared to radio signals.

“OPALS has shown that space-to-ground laser communications transmissions are practical and repeatable,” said Matthew Abrahamson, OPALS mission manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “As a bonus, OPALS has collected an enormous amount of data to advance the science of sending lasers through the atmosphere. We look forward to continuing our testing of this technology, which sends information to and from space faster than with radio signals.”

NASA to send additional Earth Science Instruments to International Space Station

 

Written by Dr. Tony Phillips
Science at NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The International Space Station has been called a stepping stone to other worlds.

NASA hasn’t forgotten, however, that the behemoth space station is also on the doorstep of Earth.

“We’re seeing the space station come into its own as an Earth-observing platform,” says Julie Robinson, chief scientist for the International Space Station Program. “It has a different orbit than other Earth-observing satellites. It’s closer to Earth, and it sees Earth at different times of day with a different schedule.”

SpaceX’s Dragon spacecraft launches taking NASA’s RapidScat to International Space Station

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new NASA mission that will boost global monitoring of ocean winds for improved weather forecasting and climate studies is among about 5,000 pounds (2,270 kilograms) of NASA science investigations and cargo now on their way to the International Space Station aboard SpaceX’s Dragon spacecraft.

The cargo ship launched on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida at 10:52pm PDT Saturday, September 20th (1:52am EDT Sunday, September 21st).

NASA - National Aeronautics and Space AdministrationPasadena, CA – The fourth SpaceX cargo mission to the International Space Station (ISS) under NASA’s Commercial Resupply Services contract, carrying the ISS-RapidScat scatterometer instrument designed and built by NASA’s Jet Propulsion Laboratory, Pasadena, California, is scheduled to launch Saturday, September 20th, from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

The one-day adjustment in the launch date was made to accommodate preparations of the SpaceX Falcon 9 rocket and was coordinated with the station’s partners and managers.

NASA’s RapidScat scatterometer to be robotically assembled at International Space Station

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s ISS-RapidScat wind-watching scatterometer, which is scheduled to launch to the International Space Station no earlier than September 19th, will be the first science payload to be robotically assembled in space since the space station itself.

This image shows the instrument assembly on the left, shrouded in white. On the right is Rapid-Scat’s nadir adapter, a very sophisticated bracket that points the scatterometer toward Earth so that it can record the direction and speed of ocean winds. The two pieces are stowed in the unpressurized trunk of a SpaceX Dragon cargo spacecraft at Cape Canaveral Air Force Station in Florida.

NASA’s QuikScat satellite to be used to calibrate it’s successor RapidScat

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – June 19th marked the 15th anniversary of the launch of NASA’s QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners.

On this anniversary, the mission’s team is calibrating ISS-RapidScat, the successor that will maintain QuikScat’s unbroken data record. After its launch in a few months, RapidScat will watch ocean winds from the International Space Station (ISS) for a two-year mission.

Using data from NASA's QuikScat, weather forecasters were able to predict hazardous weather events over oceans 6 to 12 hours earlier than before these data were available. Orange areas show where winds are blowing the hardest and blue shows relatively light winds. (NASA)
