NASA’s Orbiting Carbon Observatory-3 gathers data for the first time

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s newest carbon dioxide-measuring mission to launch into space, the Orbiting Carbon Observatory-3 (OCO-3), has seen the light. From its perch on the International Space Station, OCO-3 captured its first glimpses of sunlight reflected by Earth’s surface on June 25th, 2019.

Just weeks later, the OCO-3 team was able to make its first determinations of carbon dioxide and solar-induced fluorescence – the “glow” that plants emit from photosynthesis, a process that includes the capture of carbon from the atmosphere.

Small Planet discovered by NASA’s Transiting Exoplanet Survey Satellite

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – A world between the sizes of Mars and Earth orbiting a bright, cool, nearby star has been discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS). The planet, called L 98-59b, marks the tiniest discovered by TESS to date.

Two other worlds orbit the same star. While all three planets’ sizes are known, further study with other telescopes will be needed to determine if they have atmospheres and, if so, which gases are present. The L 98-59 worlds nearly double the number of small exoplanets — that is, planets beyond our solar system — that have the best potential for this kind of follow-up.

NASA reports Small Asteroid breaks up in Earth’s Atmosphere

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says last Saturday, June 22nd, 2019, a lightning detector on a NOAA weather satellite picked up something that wasn’t lightning. A scientist at the Center for Near Earth Object Studies at NASA’s Jet Propulsion Laboratory in Pasadena, California, started doing some detective work.

NASA studies Asia Mountains Water Cycle

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA says that for more than a billion people, Asia’s high mountain ranges, Himalaya, Karakoram, and Hindu Kush, are the names of their most reliable water source.

Snow and glaciers in these mountains contain the largest volume of freshwater outside of Earth’s polar ice sheets, leading hydrologists to nickname this region the Third Pole. One-seventh of the world’s population depends on rivers flowing from these mountains for water to drink and to irrigate crops.

NASA Tech Missions headed to Space aboard SpaceX Falcon Heavy Rocket

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA technology demonstrations have launched into space on a SpaceX Falcon Heavy Rocket. These missions will look at the space environment around Earth and how it affects us. This could one day could help NASA astronauts to Mars, and science missions, 

The NASA missions – including the Deep Space Atomic Clock and two instruments from NASA’S Jet Propulsion Laboratory in Pasadena, California – lifted off at 11:30pm PDT (1:30am CDT) Tuesday from NASA’s Kennedy Space Center in Florida, as part of the U.S. Department of Defense’s Space Test Program-2 (STP-2) launch.

A SpaceX Falcon Heavy rocket is ready for launch on the pad at Launch Complex 39A at NASA's Kennedy Space Center in Florida on June 24, 2019. SpaceX and the U.S. Department of Defense will launch two dozen satellites to space, including four NASA payloads that are part of the Space Test Program-2, managed by the U.S. (NASA/Kim Shiflett)

NASA’s Deep Space Atomic Clock to help Astronauts get to Mars

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – In the future, spacecraft could safely and autonomously fly themselves to destinations like the Moon and Mars thanks to NASA navigators.

Navigators today tell a spacecraft where to go by calculating its position from Earth and sending the location data to space in a two-way relay system that can take anywhere from minutes to hours to deliver directions. This method of navigation means that no matter how far a mission travels through the solar system, our spacecraft are still tethered to the ground, waiting for commands from our planet.

The Deep Space Atomic Clock, a new technology from NASA's JPL, may change the way spacecraft navigate in space. Launching in late June aboard the Orbital Test Bed satellite, on the SpaceX's Falcon Heavy rocket, descendants of the technology demonstration could be a key component of a self-driving spacecraft and a GPS-like navigation system at other worlds.

NASA’s Spitzer Space Telescope to be turned off January 30th, 2020

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – On January 30th, 2020, NASA’s Spitzer Space Telescope will be switched off permanently  after nearly 16 years of exploring the cosmos in infrared light. By then, the spacecraft will have operated for more than 11 years beyond its prime mission, thanks to the Spitzer engineering team’s ability to address unique challenges as the telescope slips farther and farther from Earth.

Managed and operated by NASA’s Jet Propulsion Laboratory in Pasadena, California, Spitzer is a small but transformational observatory. It captures infrared light, which is often emitted by “warm” objects that aren’t quite hot enough to radiate visible light.

NASA discovers portions of Jupiter’s Moon Europa’s surface is Table Salt

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says that on the surface of Jupiter’s moon Europa a familiar ingredient has been hiding in plain sight. Using a visible-light spectral analysis, planetary scientists at Caltech and NASA’s Jet Propulsion Laboratory in Pasadena, California, have discovered that the yellow color visible on portions of the surface of Europa is actually sodium chloride, a compound known on Earth as table salt, which is also the principal component of sea salt.

The discovery suggests that the salty subsurface ocean of Europa may chemically resemble Earth’s oceans more than previously thought, challenging decades of supposition about the composition of those waters. The finding was published by Science Advances on June 12th.

Tara Regio is the yellowish area to left of center, in this NASA Galileo image of Europa's surface. This region of geologic chaos is the area researchers identified an abundance of sodium chloride. (NASA/JPL/University of Arizona)

NASA’s Starshade technology to aid observations of far off Planets

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says the feat of staying highly synchronized while airborne can be appreciated by anyone who’s ever seen aircraft engaged in formation flying. In work sponsored by NASA’s Exoplanet Exploration Program (ExEP), engineers at the Jet Propulsion Laboratory in Pasadena, California, are taking formation flying to a new extreme.

Their work marks an important milestone within a larger program to test the feasibility of a technology called a starshade. Although starshades have never flown in space, they hold the potential to enable groundbreaking observations of planets beyond our solar system, including pictures of planets as small as Earth.

This artist's concept shows the geometry of a space telescope aligned with a starshade, a technology used to block starlight in order to reveal the presence of planets orbiting that star. (NASA/JPL-Caltech)
