NASA picks Six Explorers Program proposals to study our Solar System

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has selected six astrophysics Explorers Program proposals for concept studies. The proposed missions would study gamma-ray and X-ray emissions from clusters of galaxies and neutron star systems, as well as infrared emissions from galaxies in the early universe and atmospheres of exoplanets, which are planets outside of our solar system.

Three of these proposed missions, called FINESSE, SPHEREx and CASE, are managed by NASA’s Jet Propulsion Laboratory in Pasadena, California. FINESSE and CASE additionally have their principal investigator based at JPL.

NASA says International Space Station Crew ready for Total Solar Eclipse

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – The Expedition 52 crew wrapped up a busy week on Friday with more science work, cargo unloading and cleanup after a Russian spacewalk on Thursday. They are also busy preparing for the 2017 Total Solar Eclipse on Monday with the chance at several unique views of the event.

The crew participated in several studies including Vascular Echo Ultrasound, a Canadian Space Agency investigation that examines changes in blood vessels and the heart while the crew members are in space.

The station crew will have three chances to see the total solar eclipse from space. The third pass will offer the most coverage with the sun 84% obscured by the moon. (NASA)

NASA tells you What to Expect When Viewing the Total Solar Eclipse

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – What does a partial eclipse look like, anyway?

A new web-based tool from NASA lets anyone preview the event from any location, making it easy to see the difference between the total eclipse traversing a narrow band of the country on August 21st, 2017,  and the partial event most Americans will experience.

The Eyes on the Eclipse application allows users to simulate a view of the eclipse from any point on the planet, and can be used with any web browser:

NASA releases Television Coverage for August 21st Total Solar Eclipse

 

Written by Dwayne Brown
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Monday, August 21st, 2017,  all of North America will be treated to an eclipse of the Sun, and NASA Television will carry it live from coast to coast from unique vantage points on the ground and from aircraft and spacecraft, including the International Space Station. Coverage will be featured during the live four-hour broadcast Eclipse Across America: Through the Eyes of NASA.

Programming begins at 11:00am CDT (noon EDT) with a preview show hosted from Charleston, South Carolina. The main show begins at 12:00pm CDT (1:00pm EDT) and will cover the path of totality the eclipse will take across the United States, from Oregon to South Carolina.

NASA’s Balloon Program to take on new missions

 

Written by Raleigh McElvery
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD –  For decades, NASA has released enormous scientific balloons into Earth’s atmosphere, miles above the altitude of commercial flights. The Balloon Program is currently preparing new missions bearing sensitive instruments, including one designed to investigate the birth of our universe and another with ballooning origins that will fly on the International Space Station.

NASA’s Primordial Inflation Polarization Explorer (PIPER), which will launch a series of test flights over the next few years, could confirm the theory that our nascent universe expanded by a trillion trillion (1024) times immediately following the big bang.

NASA gets ready Total Solar Eclipse on August 21st

 

Written by Karen Fox
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – For the first time in 99 years, a total solar eclipse will occur across the entire continental United States, and NASA is preparing to share this experience of a lifetime on August 21st, 2017.

Viewers around the world will be provided a wealth of images captured before, during, and after the eclipse by 11 spacecraft, at least three NASA aircraft, more than 50 high-altitude balloons, and the astronauts aboard the International Space Station – each offering a unique vantage point for the celestial event.

NASA video shows Earth’s Light Show

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA has released video from the International Space Station of Earth’s Light Show in Space.

Brilliant fireworks shows on July 4th will have millions looking up, while light shows like these always have astronauts gazing back down.

NASA monitors for Bacteria and Microorganisms on International Space Station

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Wherever you find people, you also find bacteria and other microorganisms. The International Space Station is no exception.

That generally is not a problem. For one thing, the space station is kept cleaner than many environments on Earth. Routine cleaning activities are included on astronaut task schedules.

Cargo sent to the station, and the vehicles that carry it, undergo a rigorous cleaning process and monitoring for microorganisms before launch. Crew members assigned to the space station spend 10 days in pre-flight quarantine.

NASA reports International Space Station’s microgravity environment used to Help Fight Cancer

 

Written by Jenny Howard
International Space Station Program Science Office
NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – On Earth, research into antibody-drug conjugates to treat cancer has been around a while. The research presents a problem, though, because Earth-based laboratories aren’t able to mimic the shape of the cancer cell within the body, which can sometimes produce incorrect findings.

The International Space Station’s unique microgravity environment allows scientists to approach the research from a new, 3-D angle.

NASA reports Short Spacewalk Complete After Successful Installation Work

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer of NASA concluded their spacewalk at the International Space Station at 9:06pm CDT. During the spacewalk, which lasted two hours and 46 minutes, the two astronauts successfully replaced a computer relay box, and installed a pair of antennas on station to enhance wireless communication for future spacewalks.

Spacewalkers have now spent a total of 1,250 hours and 41 minutes working outside the station during 201 spacewalks in support of assembly and maintenance of the orbiting laboratory.
