NASA InSight Lander Arrives on Martian Surface to Learn What Lies Beneath (Press Release)

Mars has just received its newest robotic resident. NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) lander successfully touched down on the Red Planet after an almost seven-month, 300-million-mile (458-million-kilometer) journey from Earth.

InSight’s two-year mission will be to study the deep interior of Mars to learn how all celestial bodies with rocky surfaces, including Earth and the Moon, formed.

InSight launched from Vandenberg Air Force Base in California May 5. The lander touched down Monday, Nov. 26, near Mars' equator on the western side of a flat, smooth expanse of lava called Elysium Planitia, with a signal affirming a completed landing sequence at approximately noon PST (3 p.m. EST).

"Today, we successfully landed on Mars for the eighth time in human history,” said NASA Administrator Jim Bridenstine. “InSight will study the interior of Mars, and will teach us valuable science as we prepare to send astronauts to the Moon and later to Mars. This accomplishment represents the ingenuity of America and our international partners and it serves as a testament to the dedication and perseverance of our team. The best of NASA is yet to come, and it is coming soon.”

The landing signal was relayed to NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, via one of NASA's two small experimental Mars Cube One (MarCO) CubeSats, which launched on the same rocket as InSight and followed the lander to Mars. They are the first CubeSats sent into deep space. After successfully carrying out a number of communications and in-flight navigation experiments, the twin MarCOs were set in position to receive transmissions during InSight's entry, descent and landing.

From Fast to Slow

"We hit the Martian atmosphere at 12,300 mph (19,800 kilometers per hour), and the whole sequence to touching down on the surface took only six-and-a-half minutes," said InSight project manager Tom Hoffman at JPL. "During that short span of time, InSight had to autonomously perform dozens of operations and do them flawlessly — and by all indications that is exactly what our spacecraft did."

Confirmation of a successful touchdown is not the end of the challenges of landing on the Red Planet. InSight's surface-operations phase began a minute after touchdown. One of its first tasks is to deploy its two decagonal solar arrays, which will provide power. That process begins 16 minutes after landing and takes another 16 minutes to complete.

The InSight team expects a confirmation later Monday that the spacecraft's solar panels successfully deployed. Verification will come from NASA's Odyssey spacecraft, currently orbiting Mars. That signal is expected to reach InSight's mission control at JPL about five-and-a-half hours after landing.

"We are solar powered, so getting the arrays out and operating is a big deal," said Hoffman. "With the arrays providing the energy we need to start the cool science operations, we are well on our way to thoroughly investigate what's inside of Mars for the very first time."

InSight will begin to collect science data within the first week after landing, though the teams will focus mainly on preparing to set InSight's instruments on the Martian ground. At least two days after touchdown, the engineering team will begin to deploy InSight's 5.9-foot-long (1.8-meter-long) robotic arm so that it can take images of the landscape.

"Landing was thrilling, but I'm looking forward to the drilling," said InSight principal investigator Bruce Banerdt of JPL. "When the first images come down, our engineering and science teams will hit the ground running, beginning to plan where to deploy our science instruments. Within two or three months, the arm will deploy the mission's main science instruments, the Seismic Experiment for Interior Structure (SEIS) and Heat Flow and Physical Properties Package (HP3) instruments."

InSight will operate on the surface for one Martian year, plus 40 Martian days, or sols, until Nov. 24, 2020. The mission objectives of the two small MarCOs which relayed InSight’s telemetry was completed after their Martian flyby.

"That's one giant leap for our intrepid, briefcase-sized robotic explorers," said Joel Krajewski, MarCOproject manager at JPL. "I think CubeSats have a big future beyond Earth's orbit, and the MarCO team is happy to trailblaze the way."

With InSight’s landing at Elysium Planitia, NASA has successfully soft-landed a vehicle on the Red Planet eight times.

"Every Mars landing is daunting, but now with InSight safely on the surface we get to do a unique kind of science on Mars," said JPL director Michael Watkins. "The experimental MarCO CubeSats have also opened a new door to smaller planetary spacecraft. The success of these two unique missions is a tribute to the hundreds of talented engineers and scientists who put their genius and labor into making this a great day."

JPL manages InSight for NASA's Science Mission Directorate. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. The MarCO CubeSats were built and managed by JPL. Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.

A number of European partners, including France's Centre National d'Études Spatiales (CNES) and the German Aerospace Center (DLR), are supporting the InSight mission. CNES, and the Institut de Physique du Globe de Paris (IPGP), provided the SEIS instrument, with significant contributions from the Max Planck Institute for Solar System Research (MPS) in Germany, the Swiss Institute of Technology (ETH) in Switzerland, Imperial College and Oxford University in the United Kingdom, and JPL. DLR provided the HP3 instrument, with significant contributions from the Space Research Center (CBK) of the Polish Academy of Sciences and Astronika in Poland. Spain's Centro de Astrobiología (CAB) supplied the wind sensors.

Photos of the Day: The Moon on a Clear Autumn Afternoon...

A snapshot of the Moon (in its Waxing Gibbous phase) that I took with my Nikon D3300 DSLR camera...on November 18, 2018.

I would devote this Blog entry to how there's less than 24 hours remaining before NASA's InSight lander touches down on Mars, but I don't wanna jinx it! So here are two pics of the Moon (which was in its Waxing Gibbous phase) that I shot with my Nikon D3300 DSLR camera a week ago today. These photos were taken exactly at this time last that's why I mentioned that this image was shot on a clear autumn afternoon. The shutter speed and aperture setting on my DSLR makes it look like these pics were taken at night (well, at least the photo above implies that), but they weren't. Anyways, that's all. Less than 24 hours remain before NASA's InSight lander touches down on Mars!

Sorry, I couldn't resist.

T-Minus 2 DAYS Till InSight Arrives on Mars!

At this moment two days from now, NASA's InSight lander will have hopefully touched down on the surface of Mars. Around 12:01 PM, Pacific Standard Time (3:01 PM, Eastern Standard Time) on November 26, which is Cyber Monday, NASA should receive radio confirmation that the 3-legged robotic probe landed at Elysium Planitia...a broad plain located near the equator of the Red Planet. Just like the Phoenix lander a decade ago and the Curiosity rover 6 years ago, I plan to witness this exciting event during a viewing party near downtown Pasadena in California. More details about this on Monday—assuming everything goes as planned and I'm blogging nothing but good news when I get home! Carry on.

NASA’s Quiet Supersonic Technology Project Passes Major Milestone (Press Release - November 19)

NASA has officially committed to a development timeline that will lead to the first flight of its X-59 Quiet Supersonic Technology (QueSST) aircraft in just three years.

This critical milestone comes after a rigorous review, Key Decision Point-C (KDP-C), that confirmed NASA’s continued support of the X-59, in terms of funding, and established an achievable development timeline for NASA’s first piloted, full-size X-plane in more than three decades.

“This aircraft has the potential to transform aviation in the United States and around the world by making faster-than-sound air travel over land possible for everyone,” said NASA Administrator Jim Bridenstine. “We can’t wait to see this bird fly!”

KDP-C commits NASA to the full X-59 development effort through flight-testing in 2021. The cost and schedule commitments outlined in KDP-C align the project with program management best practices that account for potential technical risks and budgetary uncertainty beyond the project’s control.

“This is a monumental milestone for the project,” said Jaiwon Shin, NASA’s associate administrator for aeronautics. “I’m extremely proud of the team for its hard work getting to this point, and we all look forward to watching this aircraft take shape and then take flight.”

The X-59 QueSST is shaped to reduce the loudness of a sonic boom to that of a gentle thump, if it’s heard at all. The supersonic aircraft will be flown above select U.S. communities to measure public perception of the noise – data that will help regulators establish new rules for commercial supersonic air travel over land.

Management of X-59 QueSST development falls under the Low Boom Flight Demonstrator project, part of the Integrated Aviation Systems Program in NASA’s Aeronautics Research Mission Directorate.

NASA Reveals the Landing Site for the Mars 2020 Rover One Week Before the InSight Lander Arrives at the Red Planet!

NASA Announces Landing Site for Mars 2020 Rover (Press Release)

NASA has chosen Jezero Crater as the landing site for its upcoming Mars 2020 rover mission after a five year search, during which every available detail of more than 60 candidate locations on the Red Planet was scrutinized and debated by the mission team and the planetary science community.

The rover mission is scheduled to launch in July 2020 as NASA’s next step in exploration of the Red Planet. It will not only seek signs of ancient habitable conditions – and past microbial life -- but the rover also will collect rock and soil samples and store them in a cache on the planet's surface. NASA and ESA (European Space Agency) are studying future mission concepts to retrieve the samples and return them to Earth, so this landing site sets the stage for the next decade of Mars exploration.

“The landing site in Jezero Crater offers geologically rich terrain, with landforms reaching as far back as 3.6 billion years old, that could potentially answer important questions in planetary evolution and astrobiology,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “Getting samples from this unique area will revolutionize how we think about Mars and its ability to harbor life.”

Jezero Crater is located on the western edge of Isidis Planitia, a giant impact basin just north of the Martian equator. Western Isidis presents some of the oldest and most scientifically interesting landscapes Mars has to offer. Mission scientists believe the 28-mile-wide (45-kilometer) crater, once home to an ancient river delta, could have collected and preserved ancient organic molecules and other potential signs of microbial life from the water and sediments that flowed into the crater billions of years ago.

Jezero Crater’s ancient lake-delta system offers many promising sampling targets of at least five different kinds of rock, including clays and carbonates that have high potential to preserve signatures of past life. In addition, the material carried into the delta from a large watershed may contain a wide variety of minerals from inside and outside the crater.

The geologic diversity that makes Jezero so appealing to Mars 2020 scientists also makes it a challenge for the team’s entry, descent and landing (EDL) engineers. Along with the massive nearby river delta and small crater impacts, the site contains numerous boulders and rocks to the east, cliffs to the west, and depressions filled with aeolian bedforms (wind-derived ripples in sand that could trap a rover) in several locations.

“The Mars community has long coveted the scientific value of sites such as Jezero Crater, and a previous mission contemplated going there, but the challenges with safely landing were considered prohibitive,” said Ken Farley, project scientist for Mars 2020 at NASA’s Jet Propulsion Laboratory. “But what was once out of reach is now conceivable, thanks to the 2020 engineering team and advances in Mars entry, descent and landing technologies.”

When the landing site search began, mission engineers already had refined the landing system such that they were able to reduce the Mars 2020 landing zone to an area 50 percent smaller than that for the landing of NASA’s Curiosity rover at Gale Crater in 2012. This allowed the science community to consider more challenging landing sites. The sites of greatest scientific interest led NASA to add a new capability called Terrain Relative Navigation (TRN). TRN will enable the “sky crane” descent stage, the rocket-powered system that carries the rover down to the surface, to avoid hazardous areas.

The site selection is dependent upon extensive analyses and verification testing of the TRN capability. A final report will be presented to an independent review board and NASA Headquarters in the fall of 2019.

“Nothing has been more difficult in robotic planetary exploration than landing on Mars,” said Zurbuchen. “The Mars 2020 engineering team has done a tremendous amount of work to prepare us for this decision. The team will continue their work to truly understand the TRN system and the risks involved, and we will review the findings independently to reassure we have maximized our chances for success.”

Selecting a landing site this early allows the rover drivers and science operations team to optimize their plans for exploring Jezero Crater once the rover is safely on the ground. Using data from NASA’s fleet of Mars orbiters, they will map the terrain in greater detail and identify regions of interest – places with the most interesting geological features, for example – where Mars 2020 could collect the best science samples.

The Mars 2020 Project at JPL manages rover development for SMD. NASA's Launch Services Program, based at the agency's Kennedy Space Center in Florida, is responsible for launch management. Mars 2020 will launch from Cape Canaveral Air Force Station in Florida.

Rest In Peace, Stan Lee (1922-2018)...

Stan Lee addresses the crowd at his Comikaze Expo in downtown Los Angeles, on November 2, 2013.

This month marks five years since I saw Stan Lee in person at his Comikaze Expo in Los Angeles. While the Marvel Universe and comic book fandom as a whole won't be the same without the legendary Lee to look up to after he passed away today, this is both a sad and joyous moment. It's a joyous moment because we can forever remember the Marvel visionary as a person whose amazing superhero creations—ranging from Fantastic Four, Iron Man and Spider-Man to Black Panther and The Avengers—are popular icons that millions of fans around the world can continue to be inspired by...both on paper and on the big screen. At 95 years-old, Stan Lee lived a full life that had a positive impact on dreamers around the globe. So I won't end this entry by saying 'Rest In Peace' again, but by exclaiming Excelsior!

Photo of the Day: An Orange Half-Moon in the Sky...

A snapshot I took of the Waxing Crescent Moon...which was tinted orange by smoke coming from the Woolsey Fire near Malibu, California, on November 10, 2018.

Just thought I'd share this pic (shot with my Nikon D3300 DSLR camera) that I took of tonight's Waxing Crescent Moon...which is tinted orange from all of the smoke coming from the Woolsey Fire still burning near Malibu (about 74 miles from where I live in Pomona), California. The last time I took photos of the Moon, it was back in late January...when it had a crimson hue due to the fact that it was a Super Blue Blood Moon (a.k.a. a Supermoon that was also a Blue Moon which occurred during a lunar eclipse, also called a Blood Moon). Like that winter snapshot, I wish today's image was also taken in less dire circumstances.

My sympathies to those who lost their loved ones and homes during the tragic wildfires currently raging in northern and southern California.

America Is Slowly Regaining Its Soul...

Even though the Republicans retained control of the Senate, Russian patsy Donald Trump will STILL be screwed by the House Democrats.

I have to get things ready for work tomorrow, so I'll just leave these images here for your enjoyment. Do your research online, and you'll know why a Democrat-led House of Representatives is good for the United States, and bad for Donald Trump.

Speaking of Trump, looks like he'll have to find another Cox-sucker to do his bidding here in California. Congrats to Gavin Newsom, who will soon become my state's next governor! Carry on.

Can't wait for you to release Trump's tax returns, House Democrats!

The Sun Has Set on Dawn's Mission...

NASA’s Dawn Mission to Asteroid Belt Comes to End (Press Release)

NASA’s Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system’s earliest chapter.

Dawn missed scheduled communications sessions with NASA's Deep Space Network on Wednesday, Oct. 31, and Thursday, Nov. 1. After the flight team eliminated other possible causes for the missed communications, mission managers concluded that the spacecraft finally ran out of hydrazine, the fuel that enables the spacecraft to control its pointing. Dawn can no longer keep its antennae trained on Earth to communicate with mission control or turn its solar panels to the Sun to recharge.

The Dawn spacecraft launched 11 years ago to visit the two largest objects in the main asteroid belt. Currently, it’s in orbit around the dwarf planet Ceres, where it will remain for decades.

“Today, we celebrate the end of our Dawn mission – its incredible technical achievements, the vital science it gave us, and the entire team who enabled the spacecraft to make these discoveries,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington. “The astounding images and data that Dawn collected from Vesta and Ceres are critical to understanding the history and evolution of our solar system.”

Dawn launched in 2007 on a journey that put about 4.3 billion miles (6.9 billion kilometers) on its odometer. Propelled by ion engines, the spacecraft achieved many firsts along the way. In 2011, when Dawn arrived at Vesta, the second largest world in the main asteroid belt, the spacecraft became the first to orbit a body in the region between Mars and Jupiter. In 2015, when Dawn went into orbit around Ceres, a dwarf planet that is also the largest world in the asteroid belt, the mission became the first to visit a dwarf planet and go into orbit around two destinations beyond Earth.

"The fact that my car's license plate frame proclaims, 'My other vehicle is in the main asteroid belt,' shows how much pride I take in Dawn," said Mission Director and Chief Engineer Marc Rayman at NASA's Jet Propulsion Laboratory (JPL). "The demands we put on Dawn were tremendous, but it met the challenge every time. It's hard to say goodbye to this amazing spaceship, but it’s time."

The data Dawn beamed back to Earth from its four science experiments enabled scientists to compare two planet-like worlds that evolved very differently. Among its accomplishments, Dawn showed how important location was to the way objects in the early solar system formed and evolved. Dawn also reinforced the idea that dwarf planets could have hosted oceans over a significant part of their history – and potentially still do.

“In many ways, Dawn’s legacy i­s just beginning,” said Princ­­ipal Investigator Carol Raymond at JPL. “Dawn’s data sets will be deeply mined by scientists working on how planets grow and differentiate, and when and where life could have formed in our solar system. Ceres and Vesta are important to the study of distant planetary systems, too, as they provide a glimpse of the conditions that may exist around young stars.”

Because Ceres has conditions of interest to scientists who study chemistry that leads to the development of life, NASA follows strict planetary protection protocols for the disposal of the Dawn spacecraft. Dawn will remain in orbit for at least 20 years, and engineers have more than 99 percent confidence the orbit will last for at least 50 years.

So, while the mission plan doesn't provide the closure of a final, fiery plunge – the way NASA’s Cassini spacecraft ended last year, for example – at least this is certain: Dawn spent every last drop of hydrazine making science observations of Ceres and radioing them back so we could learn more about the solar system we call home.

The Dawn mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. JPL is responsible for overall Dawn mission science. Northrop Grumman in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.
