AAA reports Gas Demand at All-Time High, Slowing Pump Price Decreases

 

AAATampa, FL – AAA says summer may be ending, but gasoline demand is soaring to new heights. In its latest reading, the Energy Information Administration (EIA) recorded demand at 9.93 million b/d, the highest since the agency began recording data in 1991.

As demand jumped, gasoline stocks fell by 1.4 million bbl and pump prices slowed their decline on the week.

NASA’s Spitzer Space Telescope observes conditions on Rocky Planet

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Spitzer Space Telescope data has been used in a new study to provide a rare glimpse of conditions on the surface of a rocky planet orbiting a star beyond the Sun. The study, published today in the journal Nature, shows that the planet’s surface may resemble those of Earth’s Moon or Mercury:

The planet likely has little to no atmosphere and could be covered in the same cooled volcanic material found in the dark areas of the Moon’s surface, called mare.

This artist's illustration depicts the exoplanet LHS 3844b, which is 1.3 times the mass of Earth and orbits an M dwarf star. The planet's surface may be covered mostly in dark lava rock, with no apparent atmosphere, according to observations by NASA's Spitzer Space Telescope. (NASA/JPL-Caltech/R. Hurt (IPAC))

NASA confirms mission to Jupiter’s Moon, Europa

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA has announced the mission to explore Jupiter’s moon Europa is a go.

An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission’s next phase. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science payload.

NASA’s Artemis Program Human Lunar Lander Development to be lead by Marshall Space Flight Center

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA Administrator Jim Bridenstine was joined Friday by U.S. Representatives Mo Brooks and Robert Aderholt of Alabama and Scott DesJarlais of Tennessee at the agency’s Marshall Space Flight Center in Huntsville, Alabama, to announce the center’s new role leading the agency’s Human Landing System Program for its return to the Moon by 2024.

“Marshall Space Flight Center is the birthplace of America’s space program. It was Marshall scientists and engineers who designed, built, tested, and helped launch the giant Saturn V rocket that carried astronauts on the Apollo missions to the Moon,” Brooks said.

On Aug. 16, 2019, NASA Administrator Jim Bridenstine announced the agency’s Marshall Space Flight Center in Huntsville, Alabama, will lead the Human Landing System Program.

AAA reports Domestic Gasoline Stocks Soar, Push Down Gas Prices

 

AAATampa, FL – AAA says the national gas price average, $2.64, represents a seven-cent drop on the week as domestic gasoline stocks built by a surprising 4.4 million bbl, according to the Energy Information Administration’s (EIA) latest data.

Contributing to the build was at least 1.2 million b/d of imports at U.S. ports. With the large bump, stocks now sit 235 million bbl – a U.S. stock level not seen in nearly five months (end of March).

NASA picks Study Proposals for understanding Fundamental Nature of Space

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. Two Proposals have been picked by NASA for concept studies that could help us better understand the fundamental nature of space and how it changes in response to planetary atmospheres, radiation from the Sun, and interstellar particles. The proposals will advance NASA’s heliophysics program and could lead to better protection for both technology and humans as we travel farther from home.

Each of these Heliophysics Science Mission of Opportunity proposals will receive $400,000 to conduct a nine-month mission concept study.

NASA has chosen two new science proposals for nine-month concept studies to advance our understanding of how the particles and energy in space – shown here flowing from the Sun in an illustration of the solar wind – affect the fundamental nature of space. One proposal will ultimately be chosen to launch along with NASA’s upcoming Interstellar Mapping and Acceleration Probe in October 2024. (NASA)

NASA launches Student-built CubeSat Into Space with SlingShot

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA reports that the student-built CubeSat—Radio Frequency Tag Satellite (RFTSat)— was deployed in space on August 7th, 2019 using a one of a kind deployment dispenser called SlingShot.  This image shows the Cygnus cargo spacecraft departing the space station with SlingShot payloads in preparation for deployment activities.

RFTSat was designed by students and faculty at Northwest Nazarene University in Nampa, Idaho, and was selected through NASA’s CubeSat Launch Initiative (CSLI) to fly as an auxiliary payload on SpaceX’s 18th commercial cargo resupply services mission to the International Space Station—which launched July 25th, 2019 from Cape Canaveral, Florida.

NASA’s Mars 2020 Rover gains Bit Carousel

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Mars 2020 rover now has the bit carousel installed, a mechanism that will play a key role in the acquisition, containment and eventual return to Earth of humanity’s first samples from another planet.

“The bit carousel is at the heart of the sampling and caching subsystem,” said Keith Rosette, Mars 2020 sample handling delivery manager at NASA’s Jet Propulsion Laboratory in Pasadena, California. “It contains all of the tools the coring drill uses to sample the Martian surface and is the gateway for the samples to move into the rover for assessment and processing.”

In this August 5, 2019 image, the bit carousel - the heart of sampling and caching subsystem of NASA’s Mars 2020 mission - is attached to the front end of the rover. (NASA/JPL-Caltech)

NASA’s OSIRIS-REx Spacecraft has Four Possible Sites to gather samples on Asteroid Bennu

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The team leading NASA’s first asteroid sample return mission has selected four potential sites for the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft to “tag” its cosmic dance partner after months grappling with the rugged reality of asteroid Bennu’s surface.

Since its arrival in December 2018, the OSIRIS-REx spacecraft has mapped the entire asteroid in order to identify the safest and most accessible spots for the spacecraft to collect a sample. These four sites now will be studied in further detail in order to select the final two sites – a primary and backup – in December.

Pictured are the four candidate sample collection sites on asteroid Bennu selected by NASA’s OSIRIS-REx mission. Site Nightingale (top left) is located in Bennu’s northern hemisphere. Sites Kingfisher (top right) and Osprey (bottom left) are located in Bennu’s equatorial region. Site Sandpiper (bottom right) is located in Bennu’s southern hemisphere. In December, one of these sites will be chosen for the mission’s touchdown event. (NASA/University of Arizona)

NASA’s Orion’s Service Module passes Propulsion Test

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In order to send astronauts to the Moon for Artemis missions, NASA is working on building a new system that includes tests to make sure the Orion spacecraft is prepared to safely carry crew on an alternate mission profile in the face of unexpected problems.

That capability was most recently demonstrated with a successful, continuous 12-minute firing of Orion’s propulsion system that simulated a possible alternate mission scenario.
