Peculiar Sounds on Mars: What NASA's InSight Robot Lander 'Hears'

Peculiar Sounds on Mars

What NASA's InSight Robot Lander 'Hears'

NASA's InSight lander placed a seismometer on the Martian surface to study marsquakes. While it's found many, it has also detected other kinds of seismic signals, including some produced by the spacecraft itself. That includes wind gusts, InSight's robotic arm moving around and "dinks and donks," friction caused by parts inside the seismometer moving against each other as the temperature changes.

Put on your headphones and you can hear sonifications of this seismic "noise" recorded on March 6, 2019, the 98th Martian day, or sol, of the mission. Around 2 p.m. local Mars time, the spacecraft's arm was moving and snapping pictures with its cameras, surveying InSight’s “workspace.”


This audio would be too faint for the human ear to heart it on Mars. It's been sped up by 10 times and processed so you can hear the kinds of signals InSight sends back for its scientists to study.

A Flock of Astronauts & Cosmonauts | ESA

A Flock of Astronauts & Cosmonauts | ESA

Location: International Space Station
When Earth is so far away, it helps to have friends nearby.
The usual six-astronaut crew of the International Space Station welcomed three more and a cargo vehicle last week, making for a full house on the orbital outpost.

The arrival of NASA astronaut Jessica Meir, Russian cosmonaut Oleg Skripochka and the first United Arab Emirates (UAE) astronaut Hazza Al Mansouri on Friday was followed by the Japanese HTV-8 space freighter the next day, bringing over four tonnes of supplies and fresh science.

With nine people now on board, the Space Station is even busier and nosier than usual, including at mealtimes.

European Space Agency astronaut Luca Parmitano tweeted this image of the team gathered for a celebratory dinner in the Russian Zvezda module, the food preparation area of the Space Station. He captioned it:

“Celebrating three birthdays in one week (me, and Nick Hague and Alexei Ovchinin), wearing the t-shirts of our ‘space band’: ‘Kryk Chayky’- ‘The cry of the seagull.’”

The seagulls, like shared mealtimes, are one way the crew cope with the oddities of life in space. From isolation and disturbed day-night rhythms to the hums and buzzes of the Space Station, living in space can be stressful. Astronauts try to maintain a routine that includes social time to unwind and build comradery.

This is especially important in a multicultural environment. A total of 239 people from 19 countries have visited the space home, and as of Luca’s current mission Beyond, there are 4 nationalities on board.

Luca is preparing to take over command of the Space Station, when current commander cosmonaut Alexei Ovchinin, NASA astronaut Nick Hague and UAE astronaut Hazza Al Mansouri return to Earth in the early hours of October 3rd.

In the meantime, it is not all fun and band practice for the crew. They are hard at work on science experiments and, perhaps more importantly this week, station maintenance. Read more about the experiments and chores in the biweekly roundup:

ALMA explores a Cosmic Jellyfish | ESO

ALMA explores a Cosmic Jellyfish | ESO

Using the detailed eyes of the Atacama Large Millimeter/submillimeter Array (ALMA) and the European Southern Observatory's Very Large Telescope (VLT), astronomers have mapped the intense tails of a cosmic jellyfish: a number of knotty streams of gas spewing outwards from a spiral galaxy named ESO 137-001.

This celestial cnidarian is shown here in beautiful detail. The various elements making up this image were captured by different telescopes. The galaxy and its surroundings were imaged by the NASA/ESA Hubble Space Telescope; its tails, which trace streams of hydrogen and show up in hues of bright purple, by the MUSE instrument mounted on the VLT; and bright hotspots of carbon dioxide emission from within the system, which show up as flares of orange-red, were spotted by ALMA.


These tails are caused by a dramatic phenomenon known as ram-pressure stripping. The space between galaxies in a cluster is not empty, but full of material that acts like a viscous fluid. As a galaxy travels through this resistant environment, gas is stripped out of the galaxy to form a wake that creates beautiful, intricate systems such as that seen here around ESO 137-001 (which resides in the Norma galaxy cluster). The direction and position of the tail shed light on the way in which the galaxy is moving—with galaxies usually falling towards the center of the cluster itself.

This image offers the first high-resolution map of the cold molecular gas lurking within a ram-pressure stripped system. ESO 137-001 is one of the nearest jellyfish galaxies to Earth, and is particularly interesting because its long, extended tails of gas contain features known as ‘fireballs’: bursts of star formation. The precise mechanisms governing how stars form within jellyfish tails are mysterious, and this map thus provides a new window onto the conditions needed for new stars to form in such intense, changeable environments.

The ALMA array comprises 66 antennas, and is located on the Chajinator plateau in the Chilean Atacama Desert at an altitude of 5000 meters. ALMA observes the night sky from this remote location to unlock the secrets of how the Universe—and its weird and wonderful residents, ESO 137-001 included—formed and evolved, revealing more about our cosmic origins.

The Medusa Merger: Galaxy NGC 4194 | Hubble

The Medusa Merger: Galaxy NGC 4194 | Hubble

The galaxy pictured in this Hubble Picture of the Week has an especially evocative name: the Medusa merger.

Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one entity, but two. An early galaxy consumed a smaller gas-rich system, throwing out streams of stars and dust out into space. These streams, seen rising from the top of the merger galaxy, resembles the writhing snakes that Medusa, a monster in ancient Greek mythology, famously had on her head in place of hair, lending the object its intriguing name.

The legend of Medusa also held that anyone who saw her face would transform into stone. In this case, you can feast your eyes without fear on the center of the merging galaxies, a region known as Medusa's eye. All the cool gas pooling here has triggered a burst of star formation, causing it to stand out brightly against the dark cosmic backdrop.

The Medusa merger is located about 130 million light-years away in the constellation of Ursa Major (The Great Bear).

Arctic Sea Ice Reaches 2019 Minimum Extent | NASA

Arctic Sea Ice Reaches 2019 Minimum Extent | NASA

Arctic sea ice likely reached its 2019 minimum extent of 1.60 million square miles (4.15 million square kilometers) on Sept. 18, tied for second lowest summertime extent in the satellite record, according to NASA and the National Snow and Ice Data Center.

The Arctic sea ice cap is an expanse of frozen seawater floating on top of the Arctic Ocean and neighboring seas. Every year, it expands and thickens during the fall and winter and grows smaller and thinner during the spring and summer. But in the past decades, increasing temperatures have caused marked decreases in the Arctic sea ice extents in all seasons, with particularly rapid reductions in the minimum end-of-summer ice extent. The shrinking of the Arctic sea ice cover can ultimately affect local ecosystems, global weather patterns, and the circulation of the oceans.

Earth: South Pacific Swirl | International Space Station

Earth: South Pacific Swirl | International Space Station

Earth from space is always breathtaking . . . especially this view of the South Pacific.

This circular cloud formation caught the eye of an astronaut while orbiting over the South Pacific Ocean. Traveling near the southernmost reaches of its orbit, the International Space Station (ISS) was more than 3,200 kilometers (2,000 miles) east of New Zealand and more than 4,400 kilometers (2,700 miles) west of South America.

The striking colors within the cloud formation are a result of the local sunrise. When the Sun is at a low angle (relative to the atmosphere and ISS), sunlight passes through a thicker slice of the atmosphere. This can enhance the red end of the visible color spectrum, leading to the pink hues visible at the center of the image.

When photos are taken close to the day-night line (also known as the terminator), the sunlight can cast shadows that accentuate contrasting cloud heights and make the sense of circular motion more distinct to the eye. This photo was taken while the astronaut was looking back toward the night hemisphere, so the clouds become less defined as they fade into the terminator.

The astronaut who took this photograph sent a message from the ISS to ask if this specific cloud formation had been a named tropical cyclone. However, because the weather system was short-lived, the storm dissipated before making landfall, and thus was not named.

Returning flights of US astronauts from US soil

NASA astronauts Doug Hurley and Bob Behnken familiarize themselves with SpaceX’s Crew Dragon, the spacecraft that will transport them to the International Space Station as part of NASA’s Commercial Crew Program. Their upcoming flight test is known as Demo-2, short for Demonstration Mission 2.

The Crew Dragon will launch on SpaceX’s Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. In March 2019, SpaceX completed an uncrewed flight test of Crew Dragon known as Demo-1, which was designed to validate end-to-end systems and capabilities, bringing NASA closer to certification of SpaceX systems to fly a crew.

NASA is months away from setting a new course in Human Space Flight History. The Commercial Crew Program, a partnership between Boeing’s CST-100 Starliner and Space X’s Crew Dragon are leading the way for the return to flight of US astronauts from US soil. NASA's Kennedy Space Center is leading the way in these efforts.

The agency has contracted six missions with up to four astronauts, per-mission, for each company. Commercial transportation to and from the space station will maintain a crew of seven astronauts, maximizing time dedicated to scientific research on the orbiting laboratory. This research is crucial for NASA to understand and overcome the challenges of long-duration spaceflight, which will allow humans to explore farther into space than ever before.

NASA and SpaceX conducted a formal verification of the company’s emergency escape system on Sept. 18, 2019, at Kennedy Space Center’s Launch Complex 39A in Florida.

NASA astronaut Bob Behnken participated in the exercise to verify the crew can safely and quickly evacuate from the launch pad in the unlikely event of an emergency before liftoff of SpaceX’s first crewed flight test, called Demo-2.

As Boeing and SpaceX begin to make regular flights to the International Space Station for NASA’s Commercial Crew Program, the agency will continue to advance its mission to go beyond low-Earth orbit and establish a human presence on the Moon with the ultimate goal of sending astronauts to Mars.

NASA's Space to Ground: New Arrivals | Week of Sept. 27, 2019

NASA's Space to Ground: New Arrivals 

Week of Sept. 27, 2019

NASA's Space to Ground is your weekly update on what's happening aboard the International Space Station. 

Sept. 27, 2019: A Japanese space freighter is on track to deliver more than four tons of cargo to the International Space Station on Saturday morning. The Expedition 60 crew is preparing for its arrival while also researching a variety of microgravity phenomena.


Flight Engineers Christina Koch and Andrew Morgan are practicing on a computer the techniques they will use to maneuver the Canadarm2 robotic arm and capture the HTV-8 resupply ship on Saturday. The duo will be in the cupola monitoring the cargo craft’s approach when Koch will command the Canadarm2 to reach out and grapple the HTV-8 at 7:15 a.m. EDT.


Today, Astronaut Luca Parmitano of ESA (European Space Agency) started his morning playing with slime for the Non-Newtonian Fluids in Microgravity experiment. Koch and Morgan joined him for the fun research being filmed for students on Earth to excite them about space research.


New station resident Jessica Meir of NASA began her day observing and photographing protein crystal samples in a microscope. The research is exploring cancer therapies targeting a protein responsible for tumor growth and survival.


Meir and the station’s other new crewmates, cosmonaut Oleg Skripochka and spaceflight participant Hazzaa Ali Almansoori of the United Arab Emirates, joined the rest of the station crew to review their roles in the event of an emergency. All nine crewmembers practiced evacuating the station, communications and using safety hardware during the afternoon.


Commander Alexey Ovchinin and Flight Engineer Nick Hague are less than a week away from returning to Earth after 203 days in space. They are finalizing packing and readying their Soyuz MS-12 spacecraft for the undocking on Oct. 3. The duo will parachute to Earth with Almansoori aboard their Soyuz crew ship and land in Kazakhstan.
