NASA’s Lucy Mission discovers asteroid Eurybates has a Satellite

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA’s Lucy mission team is seeing double after discovering that Eurybates, the asteroid the spacecraft has targeted for flyby in 2027, has a small satellite. This “bonus” science exploration opportunity for the project was discovered using images taken by the Hubble Space Telescope’s Wide Field Camera 3 in September 2018, December 2019, and January 2020.

Launching in October 2021, Lucy will be the first space mission to study the Trojan asteroids, a population of small bodies orbiting the Sun “leading” and “trailing” Jupiter, at the same distance from the Sun as the gas giant.

NASA’s Artemis Lunar Program moves full speed ahead

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – In 2019, NASA celebrated the 50th anniversary of the agency’s Apollo 11 Moon landing, the most historic moment in space exploration, while also making significant progress toward putting the first woman and next man on the Moon by 2024 under the Artemis program.

Through America’s Moon to Mars exploration approach, Artemis gained bipartisan support this year among members of Congress, the U.S aerospace industry, as well as with international partners, including Canada, Australia, and Japan, and member states of the European Space Agency.

NASA seeks to use 3D Printing to create parts during Long Space Flights

 

NASA - National Aeronautics and Space AdministrationHouston, TX – NASA says the International Space Station has continuously been home to astronauts for more than nineteen years. Astronauts conduct scientific research using dozens of special facilities aboard the space station, which also provides them with a place to eat, sleep, relax and exercise.

To make all of this possible requires sending more than 7,000 pounds of spare parts to the station annually. Another 29,000 pounds of spaceflight hardware spares are stored aboard the station and another 39,000 on the ground, ready to fly if needed.

NASA picks spot on Asteroid Bennu to collect Samples

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – After a year scoping out asteroid Bennu’s boulder-scattered surface, the team leading NASA’s first asteroid sample return mission has officially selected a sample collection site.

The Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-Rex) mission team concluded a site designated “Nightingale” – located in a crater high in Bennu’s northern hemisphere – is the best spot for the OSIRIS-REx spacecraft to snag its sample.

This image shows sample site Nightingale, OSIRIS-REx’s primary sample collection site on asteroid Bennu. The image is overlaid with a graphic of the OSIRIS-REx spacecraft to illustrate the scale of the site. (NASA/Goddard/University of Arizona)

NASA’s Juno Spacecraft discovers new Cyclone on Jupiter

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA says Jupiter’s south pole has a new cyclone. The discovery of the massive Jovian tempest occurred on November 3rd, 2019, during the most recent data-gathering flyby of Jupiter by NASA’s Juno spacecraft. It was the 22nd flyby during which the solar-powered spacecraft collected science data on the gas giant, soaring only 2,175 miles (3,500 kilometers) above its cloud tops.

The flyby also marked a victory for the mission team, whose innovative measures kept the solar-powered spacecraft clear of what could have been a mission-ending eclipse.

NASA’s SLS Test Feul Tank pushed past it’s limits during Test

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Thursday, December 5th, 2019 deliberately pushed the world’s largest rocket fuel tank beyond its design limits to really understand its breaking point.

The test version of the Space Launch System rocket’s liquid hydrogen tank withstood more than 260% of expected flight loads over five hours before engineers detected a buckling point, which then ruptured. Engineers concluded the test at approximately 11:00pm. 

The December 5th test pushed the tank to its limits to see how much force it would take to cause the tank’s structure to fail. This image shows the resulted buckling of the structure when the tank failed after exposure to more than 260% of expected flight loads over 5 hours. (NASA/Dennis Olive)

NASA to test World’s Largest Rocket Fuel Tank

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – Engineers are preparing to push a test article identical to the world’s largest rocket fuel tank beyond its design limits and find its breaking point during upcoming tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Earlier this year, a NASA and Boeing test team subjected a test version of the Space Launch System (SLS) liquid hydrogen tank to a series of 37 tests that simulate liftoff and flight stresses by using large hydraulic pistons to push and pull on the test tank with millions of pounds of force.

This will be the largest-ever controlled test-to-failure of a NASA rocket stage fuel tank. (NASA/MSFC)

NASA’s OSIRIS-REx Spacecraft offers insight into Particles being ejected from Asteroid Bennu

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Shortly after NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission’s science team revealed that the asteroid could be active, or consistently discharging particles into space. The ongoing examination of Bennu – and its sample that will eventually be returned to Earth – could potentially shed light on why this intriguing phenomenon is occurring.

The OSIRIS-REx team first observed a particle-ejection event in images captured by the spacecraft’s navigation cameras taken on January 6th, just a week after the spacecraft entered its first orbit around Bennu.

This view of asteroid Bennu ejecting particles from its surface on Jan. 6, 2019, was created by combining two images taken by the NavCam 1 imager aboard NASA's OSIRIS-REx spacecraft: a short exposure image, which shows the asteroid clearly, and a long-exposure image (five seconds), which shows the particles clearly.

NASA develops concept for Mid-Sized Robotic Lander for the Moon

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – As NASA presses forward with the agency’s mission to the Moon, Mars and beyond, the development of top-tier technology is critical to success. With emphasis on lunar exploration and scientific investigation, the desire to deliver a wide variety of payloads to the Moon has increased.

For NASA’s Commercial Lunar Payload Services (CLPS) initiative — which is leading the effort — this is no new concept. NASA has already awarded commercial contracts for payload delivery to the lunar surface, and expects to establish additional partnerships to support upcoming lunar ventures.

NASA’s Mars InSight Lander’s Mole Has Backed Out half way of Its Hole

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – After making progress over the past several weeks digging into the surface of Mars, NASA’s InSight Lander’s mole has backed about halfway out of its hole this past weekend. Preliminary assessments point to unusual soil conditions on the Red Planet. The international mission team is developing the next steps to get it buried again.

A scoop on the end of the arm has been used in recent weeks to “pin” the mole against the wall of its hole, providing friction it needs to dig. The next step is determining how safe it is to move InSight’s robotic arm away from the mole to better assess the situation. The team continues to look at the data and will formulate a plan in the next few days.
