Five Things to Know About InSight's Mars Landing

Every Mars landing is a knuckle-whitening feat of engineering. But each attempt has its own quirks based on where a spacecraft is going and what kind of science the mission intends to gather.

On Nov. 26, NASA will try to safely set a new spacecraft on Mars. InSight is a lander dedicated to studying the deep interior of the planet - the first mission ever to do so.

Here are a few things to know about InSight's landing.

Landing on Mars is hard

Only about 40 percent of the missions ever sent to Mars - by any space agency - have been successful. The U.S. is the only nation whose missions have survived a Mars landing. The thin atmosphere - just 1 percent of Earth's - means that there's little friction to slow down a spacecraft. Despite that, NASA has had a long and successful track record at Mars. Since 1965, it has flown by, orbited, landed on and roved across the surface of the Red Planet.

InSight uses tried-and-true technology

In 2008, NASA's Jet Propulsion Laboratory in Pasadena, California, successfully landed the Phoenix spacecraft at Mars' North Pole. InSight is based on the Phoenix spacecraft, both of which were built by Lockheed Martin Space in Denver. Despite tweaks to its heat shield and parachute, the overall landing design is still very much the same: After separating from a cruise stage, an aeroshell descends through the atmosphere. The parachute and retrorockets slow the spacecraft down, and suspended legs absorb some shock from the touchdown.

InSight is landing on "the biggest parking lot on Mars"

One of the benefits of InSight's science instruments is that they can record equally valuable data regardless of where they are on the planet. That frees the mission from needing anything more complicated than a flat, solid surface (ideally with few boulders and rocks). For the mission's team, the landing site at Elysium Planitia is sometimes thought as "the biggest parking lot on Mars."

InSight was built to land in a dust storm

InSight's engineers have built a tough spacecraft, able to touch down safely in a dust storm if it needs to. The spacecraft's heat shield is designed to be thick enough to withstand being "sandblasted" by dust. Its parachute has suspension lines that were tested to be stronger than Phoenix's, in case it faces more air resistance due to the atmospheric conditions expected during a dust storm.

The entry, descent and landing sequence also has some flexibility to handle shifting weather. The mission team will be receiving daily weather updates from NASA's Mars Reconnaissance Orbiter in the days before landing so that they can tweak when InSight's parachute deploys and when it uses radar to find the Martian surface.

After landing, InSight will provide new science about rocky planets

InSight will teach us about the interior of planets like our own. The mission team hopes that by studying the deep interior of Mars, we can learn how other rocky worlds, including Earth and the Moon, formed. Our home planet and Mars were molded from the same primordial stuff more than 4.5 billion years ago but then became quite different. Why didn't they share the same fate?

When it comes to rocky planets, we've only studied one in detail: Earth. By comparing Earth's interior to that of Mars, InSight's team members hope to better understand our solar system. What they learn might even aid the search for Earth-like exoplanets, narrowing down which ones might be able to support life. So while InSight is a Mars mission, it's also much more than a Mars mission.

You can read more about how the science of the mission is unique here. A press kit released today includes additional information on the mission.

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. 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 provided the Seismic Experiment for Interior Structure (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 Heat Flow and Physical Properties Package (HP3) instrument, with significant contributions from the Polish Space Agency (CBK) and Astronika in Poland. Spain's Centro de Astrobiología (CAB) supplied the wind sensors.

NASA JPL latest news release
NASA Retires Kepler Space Telescope

After nine years in deep space collecting data that indicate our sky to be filled with billions of hidden planets - more planets even than stars - NASA's Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life.

"As NASA's first planet-hunting mission, Kepler has wildly exceeded all our expectations and paved the way for our exploration and search for life in the solar system and beyond," said Thomas Zurbuchen, associate administrator of NASA's Science Mission Directorate in Washington. "Not only did it show us how many planets could be out there, it sparked an entirely new and robust field of research that has taken the science community by storm. Its discoveries have shed a new light on our place in the universe, and illuminated the tantalizing mysteries and possibilities among the stars."

Kepler has opened our eyes to the diversity of planets that exist in our galaxy. The most recent analysis of Kepler's discoveries concludes that 20 to 50 percent of the stars visible in the night sky are likely to have small, possibly rocky, planets similar in size to Earth, and located within the habitable zone of their parent stars. That means they're located at distances from their parent stars where liquid water - a vital ingredient to life as we know it - might pool on the planet surface.

The most common size of planet Kepler found doesn't exist in our solar system - a world between the size of Earth and Neptune - and we have much to learn about these planets. Kepler also found nature often produces jam-packed planetary systems, in some cases with so many planets orbiting close to their parent stars that our own inner solar system looks sparse by comparison.

"When we started conceiving this mission 35 years ago, we didn't know of a single planet outside our solar system," said the Kepler mission's founding principal investigator, William Borucki, now retired from NASA's Ames Research Center in California's Silicon Valley. "Now that we know planets are everywhere, Kepler has set us on a new course that's full of promise for future generations to explore our galaxy."

Launched on March 6, 2009, the Kepler space telescope combined cutting-edge techniques in measuring stellar brightness with the largest digital camera outfitted for outer space observations at that time. Originally positioned to stare continuously at 150,000 stars in one star-studded patch of the sky in the constellation Cygnus, Kepler took the first survey of planets in our galaxy and became the agency's first mission to detect Earth-size planets in the habitable zones of their stars.

"The Kepler mission was based on a very innovative design. It was an extremely clever approach to doing this kind of science," said Leslie Livesay, director for astronomy and physics at NASA's Jet Propulsion Laboratory, who served as Kepler project manager during mission development. "There were definitely challenges, but Kepler had an extremely talented team of scientists and engineers who overcame them."

Four years into the mission, after the primary mission objectives had been met, mechanical failures temporarily halted observations. The mission team was able to devise a fix, switching the spacecraft's field of view roughly every three months. This enabled an extended mission for the spacecraft, dubbed K2, which lasted as long as the first mission and bumped Kepler's count of surveyed stars up to more than 500,000.

The observation of so many stars has allowed scientists to better understand stellar behaviors and properties, which is critical information in studying the planets that orbit them. New research into stars with Kepler data also is furthering other areas of astronomy, such as the history of our Milky Way galaxy and the beginning stages of exploding stars called supernovae that are used to study how fast the universe is expanding. The data from the extended mission were also made available to the public and science community immediately, allowing discoveries to be made at an incredible pace and setting a high bar for other missions. Scientists are expected to spend a decade or more in search of new discoveries in the treasure trove of data Kepler provided.

 

"We know the spacecraft's retirement isn't the end of Kepler's discoveries," said Jessie Dotson, Kepler's project scientist at NASA's Ames Research Center in California's Silicon Valley. "I'm excited about the diverse discoveries that are yet to come from our data and how future missions will build upon Kepler's results."

Before retiring the spacecraft, scientists pushed Kepler to its full potential, successfully completing multiple observation campaigns and downloading valuable science data even after initial warnings of low fuel. The latest data, from Campaign 19, will complement the data from NASA's newest planet hunter, the Transiting Exoplanet Survey Satellite, launched in April. TESS builds on Kepler's foundation with fresh batches of data in its search of planets orbiting some 200,000 of the brightest and nearest stars to the Earth, worlds that can later be explored for signs of life by missions such as NASA's James Webb Space Telescope.

NASA's Ames Research Center manages the Kepler and K2 missions for NASA's Science Mission Directorate. NASA's Jet Propulsion Laboratory in Pasadena, California, managed Kepler mission development. Ball Aerospace & Technologies Corporation in Boulder, Colorado, operates the flight system with support from the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder.

NASA's InSight Will Study Mars While Standing Still

 

DAY IN REVIEW
NASA JPL latest news release
NASA's InSight Will Study Mars While Standing Still

You don't need wheels to explore Mars.

After touching down in November, NASA's InSight spacecraft will spread its solar panels, unfold a robotic arm ... and stay put. Unlike the space agency's rovers, InSight is a lander designed to study an entire planet from just one spot.

This sedentary science allows InSight to detect geophysical signals deep below the Martian surface, including marsquakes and heat. Scientists will also be able to track radio signals from the stationary spacecraft, which vary based on the wobble in Mars' rotation. Understanding this wobble could help solve the mystery of whether the planet's core is solid.

Here are five things to know about how InSight conducts its science.

1. InSight Can Measure Quakes Anywhere on the Planet

Quakes on Earth are usually detected using networks of seismometers. InSight has only one - called SEIS (Seismic Experiment for Interior Structure) - so its science team will use some creative measurements to analyze seismic waves as they occur anywhere on the planet.

SEIS will measure seismic waves from marsquakes and meteorite strikes as they move through Mars. The speed of those waves changes depending on the material they're traveling through, helping scientists deduce what the planet's interior is made of.

Seismic waves come in a surprising number of flavors. Some vibrate across a planet's surface, while others ricochet off its center. They also move at different speeds. Seismologists can use each type as a tool to triangulate where and when a seismic event has happened.

This means InSight could have landed anywhere on Mars and, without moving, gathered the same kind of science.

2. InSight's Seismometer Needs Peace and Quiet

Seismometers are touchy by nature. They need to be isolated from "noise" in order to measure seismic waves accurately.

SEIS is sensitive enough to detect vibrations smaller than the width of a hydrogen atom. It will be the first seismometer ever set on the Martian surface, where it will be thousands of times more accurate than seismometers that sat atop the Viking landers.

To take advantage of this exquisite sensitivity, engineers have given SEIS a shell: a wind-and-thermal shield that InSight's arm will place over the seismometer. This protective dome presses down when wind blows over it; a Mylar-and-chainmail skirt keeps wind from blowing in. It also gives SEIS a cozy place to hide away from Mars' intense temperature swings, which can create minute changes in the instrument's springs and electronics.

3. InSight Has a Self-Hammering Nail

Have you ever tried to hammer a nail? Then you know holding it steady is key. InSight carries a nail that also needs to be held steady.

This unique instrument, called HP3 (Heat Flow and Physical Properties Package), holds a spike attached to a long tether. A mechanism inside the spike will hammer it up to 16 feet (5 meters) underground, dragging out the tether, which is embedded with heat sensors.

At that depth, it can detect heat trapped inside Mars since the planet first formed. That heat shaped the surface with volcanoes, mountain ranges and valleys. It may even have determined where rivers ran early in Mars' history.

4. InSight Can Land in a Safe Spot

Because InSight needs stillness - and because it can collect seismic and heat data from anywhere on the planet - the spacecraft is free to land in the safest location possible.

InSight's team selected a location on Mars' equator called Elysium Planitia - as flat and boring a spot as any on Mars. That makes landing just a bit easier, as there's less to crash into, fewer rocks to land on and lots of sunlight to power the spacecraft. The fact that InSight doesn't use much power and should have plenty of sunlight at Mars' equator means it can provide lots of data for scientists to study.

5. InSight Can Measure Mars' Wobble

InSight has two X-band antennas on its deck that make up a third instrument, called RISE (Rotation and Interior Structure Experiment). Radio signals from RISE will be measured over months, maybe even years, to study the tiny "wobble" in the rotation of the planet. That wobble is a sign of whether Mars' core is liquid or solid - a trait that could also shed light on the planet's thin magnetic field.

Collecting detailed data on this wobble hasn't happened since Mars Pathfinder's three-month mission in 1997 (although the Opportunity rover made a few measurements in 2011 while it remained still, waiting out the winter). Every time a stationary spacecraft sends radio signals from Mars, it can help scientists improve their measurements.

After Two Long Careers, QuikSCAT Rings Down the Curtain

Launched in June 1999 for an intended two-year mission, NASA's SeaWinds scatterometer instrument on the QuikSCAT spacecraft was turned off on Oct. 2 in accordance with its end-of-mission plan. QuikSCAT spent its first decade creating an unprecedented record of the speed and direction of winds at the ocean surface. Then, for another nine years, it served as the gold standard of accuracy against which new spaceborne scatterometers were calibrated.

Managed by NASA's Jet Propulsion Laboratory in Pasadena, California, QuikSCAT was a unique national resource that far surpassed NASA's original science objective for the mission. During its 10 years of observing winds over the global ocean surface, QuikSCAT measurements were used by the world's weather forecasting agencies to improve forecasts and identify and monitor hurricanes and other storms far out in the open seas. Its data also provided critical information for monitoring, researching, modeling, and forecasting the atmosphere, ocean, ice and climate.

Among its many accomplishments:

• QuikSCAT discovered that hurricane-strength winds occur frequently in the North Atlantic and North Pacific oceans, where such strong winds were not previously expected to exist.

• It provided high-resolution observations of the dramatically accelerating changes in sea ice cover on the Arctic Ocean.

• The mission's measurements were used widely beyond weather forecasting and research -- for example, to help identify efficient shipping routes, plan new offshore wind farms, and guide search-and-rescue operations at sea.

Michael Freilich, the QuikSCAT mission's original principal investigator and now director of NASA's Earth Science Division, noted, "QuikSCAT operated in space for nearly two decades, and we are certain that its impact and legacy will last much longer."

Ernesto Rodríguez, QuikSCAT project scientist at JPL, said, "The decommissioning of QuikSCAT marks the passing of an era. Many scientists and forecasters have built their careers over the last 20 years using QuikSCAT. Its data led to major discoveries on the interaction between the ocean and the atmosphere."

A few months after QuikSCAT's 10th anniversary, an age-related problem caused its spinning antenna to stop rotating, reducing its observing swath to only 19 miles (30 kilometers) wide. The extreme accuracy of this narrow swath measurement, however, allowed QuikSCAT to take on a second mission: calibrating newer satellites to enable a much longer data record of ocean winds.

Satellite instruments are regularly calibrated to ensure their readings match other data that are known to be accurate, and to correct for an instrument's normal drift in accuracy over time. QuikSCAT's exceptional stability made it invaluable in assuring that newer missions from the Indian and European space agencies and from NASA are providing apples-to-apples measurements. This function proved so important to the research community that QuikSCAT's decommissioning was postponed twice to allow time for new scatterometers to be launched and calibrated.

QuikSCAT project manager Rob Gaston of JPL said, "It's a testament to the research community's commitment to climate research that QuikSCAT's intercalibration mission has continued to receive the highest possible marks for science relevance in the reviews that NASA follows to establish funding priorities for missions like QuikSCAT. The intercalibration mission has enabled research that would not have been possible but for the remarkable stability of the SeaWinds instrument and the exceptional reliability and longevity of the QuikSCAT spacecraft."

QuikSCAT was originally a recovery mission after the loss of Japan's Advanced Earth Observing Satellite, which hosted the NASA Scatterometer (NSCAT). The QuikSCAT mission was conceived, developed and launched in less than two years. Ball Aerospace & Technologies Corp. in Boulder, Colorado, built the spacecraft bus, and JPL designed and built the SeaWinds instrument. QuikSCAT was operated by the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder.
