GREENBELT, Md. (NASA PR) — NASA hasn’t measured moonquakes since Apollo astronauts deployed a handful of measuring stations at various locations on the lunar surface and discovered unexpectedly that Earth’s only natural satellite was far from seismically inactive.
The SEIS experiment on board NASA’s InSight geophysical station recorded 174 seismic events up to the end of September 2019.
Weak earthquakes – magnitude less than three to four.
Accompanying measurements provide information about the local weather conditions.
In the coming weeks, the Mars ‘Mole’ is to be assisted more effectively by pressure from above applied with the robotic arm.
COLOGNE (DLR PR) — Mars is a seismically active planet – quakes occur several times a day. Although they are not particularly strong, they are easily measurable during the quiet evening hours. This is one of many results of the evaluation of measurement data from the NASA InSight lander, which has been operating as a geophysical observatory on the surface of Mars since 2019.
PASADENA, Calif. (NASA PR) — A new understanding of Mars is beginning to emerge, thanks to the first year of NASA’s InSight lander mission. Findings described in a set of six papers published today reveal a planet alive with quakes, dust devils and strange magnetic pulses.
Five of the papers were published in Nature. An additional paper in Nature Geoscience details the InSight spacecraft’s landing site, a shallow crater nicknamed “Homestead hollow” in a region called Elysium Planitia.
PASADENA, Calif. (NASA PR) — After nearly a year of trying to dig into the Martian surface, the heat probe belonging to NASA’s InSight lander is about to get a push. The mission team plans to command the scoop on InSight’s robotic arm to press down on the “mole,” the mini pile driver designed to hammer itself as much as 16 feet (5 meters) down. They hope that pushing down on the mole’s top, also called the back cap, will keep it from backing out of its hole on Mars, as it did twice in recent months after nearly burying itself.
BERLIN (DLR PR) — In his logbook, Instrument Lead Tilman Spohn who is back in Berlin since April and communicating with JPL via the web, gives us the latest updates regarding the InSight mission and our HP3 instrument – the ‘Mole’ – which will hammer into the Martian surface.
Logbook entry 28 October 2019
More surprises on Mars! Unfortunately, we saw that the Mole had backed-out of the Martian soil instead of going deeper as we had expected. How could that happen? After all, this Mole does not have a reverse gear as the Mole that DLR built for the ill-fated European Beagle II lander had. (That probe was designed as a sampling device that would go down and then come up again with a sample.)
PASADENA, Calif. (NASA PR) — After making progress over the past several weeks digging into the surface of Mars, InSight’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.
Meantime, the lander’s seismometer — the Seismic Experiment for Interior Structure, or, SEIS — continues to collect data on marsquakes in order to provide a better understanding of the Mars interior and why Earth and the Red Planet are so different today after sharing similarities billions of years ago. The French space agency, Centre National d’Études Spatiales (CNES) and its partners provided the SEIS instrument to NASA.
PASADENA, Calif. (NASA PR) — NASA’s InSight spacecraft has used its robotic arm to help its heat probe, known as “the mole,” dig nearly 2 centimeters (3/4 of an inch) over the past week. While modest, the movement is significant: Designed to dig as much as 16 feet (5 meters) underground to gauge the heat escaping from the planet’s interior, the mole has only managed to partially bury itself since it started hammering in February 2019.
The year 2018 was the busiest one for launches in decades. There were a total of 111 completely successful launches out of 114 attempts. It was the highest total since 1990, when 124 launches were conducted.
China set a new record for launches in 2018. The nation launched 39 times with 38 successes in a year that saw a private Chinese company fail in the country’s first ever orbital launch attempt.
PASADENA, Calif. (NASA PR) — NASA’s InSight lander, which is on a mission to explore the deep interior of Mars, positioned its robotic arm this past weekend to assist the spacecraft’s self-hammering heat probe. Known as “the mole,” the probe has been unable to dig more than about 14 inches (35 centimeters) since it began burying itself into the ground on Feb. 28, 2019.
The maneuver is in preparation for a tactic, to be tried over several weeks, called “pinning.”
PASADENA, Calif. (NASA PR) —Put an ear to the ground on Mars and you’ll be rewarded with a symphony of sounds. Granted, you’ll need superhuman hearing, but NASA’s InSight lander comes equipped with a very special “ear.”
The spacecraft’s exquisitely sensitive seismometer, called the Seismic Experiment for Interior Structure (SEIS), can pick up vibrations as subtle as a breeze. The instrument was provided by the French space agency, Centre National d’Études Spatiales (CNES), and its partners.
UPDATE: NASA has won an Emmy for interactive programming for its coverage of the SpaceX Demonstration Mission-1. Administrator Jim Bridenstine tweeted, “Congrats to all involved and those who help tell the @NASA story every day!”
WASHINGTON, DC (NASA PR) — The Academy of Television Arts & Sciences announced July 16 two award nominations for NASA for its coverage of a Mars mission and the agency’s first test of a spacecraft that will help bring crewed launches to the International Space Station back to U.S. soil.
PASADENA, Calif. (NASA/JPL-Caltech PR) — For decades, the music of The Rolling Stones has had a global reach here on Earth. Now, the band’s influence extends all the way to Mars. The team behind NASA’s InSight lander has named a Martian rock after the band: ‘Rolling Stones Rock.’
