InSight, новая марсианская миссия -- 05.05.2018
 
не надо ничего выдумывать, там всё доступно написано.

NetStation’s antenna configuration enables it to conduct
full polarimetric investigations of the subsurface – transmitting
with single-, dual-, or right circular polarization and
receiving the H- and V- components (and their phase difference)
coherently – to calculate the four Stoke’s parameters
and Circular Polarization Ration (CPR) in a manner
similar to the Mini-RF on the Lunar Reconnaisance Orbiter,
[1]. High CPR (>1) is a radar characterisitic of both very
rough surfaces and icy environments, a measurement that
has been used to identify the presence of ice in the permanently
shadowed regions of the Moon [2] and Mercury [3].
Such a technique, will greatly enhance NetStation’s ability
to distinguish between high-porosity sediments and high
volume fraction subsurface deposits of water ice.
The antenna design also enables NetStation to conduct
monostatic 3-D investigations in a cone-shaped region beneath
the lander by ‘steering’ the radiation pattern of the
radar’s transmitted pulse with phase adjustments of the four
monopole antennas. The magnitude and direction of the
propagation vector of the reflected signal can then determined
by the simultaneous measurement of the signal’s
magnetic and electrical components – a capability demonstrated
in Antarctic field tests of the Netlander GPR prototype
[4, 5]. In this way, the number, depth, orientation, and
electromagnetic characteristics of reflectors beneath the
lander can be determined.

Although designed primarily as a monostatic instrument,
for operation from a fixed lander[/size:307fb1f449], the NetStation GPR can
also be operated bistaticly, in conjunction with radar instruments
on other spacecraft.

О таком типе георадаров узнал впервые. Ну, что ж, удачи в исследованиях.
 
Хотя, думается, результаты с одной неподвижной точки будут скорее "туманными". Очевидно, что гораздо информативнее профильные наблюдения с ровера.
 
NASA selects DLR experiment for InSight mission to Mars
[quote:ef5c0ed21b]


After the successful landing of the Mars Science Laboratory Curiosity rover, NASA has selected one more lander mission to Mars. The InSight mission will reach Mars in September 2016, after a six-month journey; it has been designed to take a 'look' into the deep interior of the Red Planet; it will do this with geophysical experiments including DLR's HP3, which will penetrate several metres into the Martian subsurface to measure the soil's thermo-physical and electrical properties.

"The selection of the mission InSight by NASA demonstrates the importance of exploring our planetary neighbour. I am very pleased that DLR can contribute with their own experiment on this lander to unveiling the mysteries of the Red Planet," said Johann-Dietrich W

InSight is now the last Mars surface mission in NASA’s budget. The U.S. space agency currently is planning two other Mars missions but both are orbiters.

The Mars Atmosphere and Volatile Evolution, or Maven, mission, managed by Goddard, is scheduled to launch late next year. Then, no sooner than 2018, NASA will look to launch its Mars Next Decade mission. The orbiter, which has yet to be designed, is intended to fill a void created by NASA’s withdrawal from the European-led Mars sample-collection  campaign known as ExoMars.

The French space agency, CNES, on Dec. 11 said its board of directors has approved a $42 million investment to provide a seismometer for NASA’s InSight probe, to be launched to the surface of Mars in 2016.
In cooperation with other European laboratories, CNES will provide the Seismic Experiment for Interior Structures (SEIS) seismometer. InSight will deploy a probe to the martian surface to study Mars’ geology and internal structure.
Measuring Mars’ seismic activity is a principal goal of the mission, which will attempt to measure Mars’ internal temperatures and their variation. InSight is designed to operate for two Earth years, equivalent to one Mars year.
In addition to France, institutes in Germany, Switzerland and Britain and NASA’s Jet Propulsion Laboratory in California collaborated on the development of SEIS.
CNES and French laboratories also contributed to two instruments onboard NASA’s Curiosity rover, which landed on Mars in August.

InSight mission to find what lies beneath Martian surface

Posted: March 30, 2013

HOUSTON -- NASA's next Mars lander will launch in 2016 to take the red planet's pulse and temperature, listening for tremors, measuring underground heat and monitoring the wobble in its rotation to answer fundamental questions about what lies beneath the desert world's rust-colored surface.

Scientists expect the answers to help their understanding of how planets like Earth and Mars coalesced and evolved after the birth of the solar system, according to Bruce Banerdt, principal investigator for the InSight lander due to launch in March 2016.
"The InSight mission is a geophysical mission to Mars," Banerdt said. "It's going to go to Mars and take its vital signs. It's going to take its heartbeat - the seismic activity of the planet. It's going to take its temperature by measuring the thermal gradient of its surface, which tells us how much heat is coming out. And it's going to measure its reflexes by looking at how its rotation wobbles with the tidal effects of the sun."
Based on a proven lander design successfully demonstrated by NASA's Phoenix mission in 2008, the InSight spacecraft will make a rocket-assisted touchdown in a region named Elysium Planitia, a broad equatorial plain dotted with extinct volcanoes.
"It's very flat," Banerdt said. "There are lava flows nearby, and we have already picked out landing ellipses around the flow."

NASA Evaluates Four Candidate Sites for 2016 Mars Mission

Sept 4, 2013



NASA has narrowed to four the number of potential landing sites for the agency's next mission to the surface of Mars, a 2016 lander to study the planet's interior.

The stationary Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport (InSight) lander is scheduled to launch in March 2016 and land on Mars six months later. It will touch down at one of four sites sel ected in August from a field of 22 candidates. All four semi-finalist spots lie near each other on an equatorial plain in an area of Mars called Elysium Planitia.

"We picked four sites that look safest," said geologist Matt Golombek of NASA's Jet Propulsion Laboratory in Pasadena, Calif.  Golombek is leading the site-selection process for InSight. "They have mostly smooth terrain, few rocks and very little slope."

Scientists will focus two of NASA's Mars Reconnaissance Orbiter cameras on the semi-finalists in the coming months to gain data they will use to sel ect the best of the four sites well before InSight is launched.

The mission will investigate processes that formed and shaped Mars and will help scientists better understand the evolution of our inner solar system's rocky planets, including Earth. Unlike previous Mars landings, what is on the surface in the area matters little in the choice of a site except for safety considerations.

"This mission's science goals are not related to any specific location on Mars because we're studying the planet as a whole, down to its core," said Bruce Banerdt, InSight principal investigator at JPL. "Mission safety and survival are what drive our criteria for a landing site."

Each semifinalist site is an ellipse measuring 81 miles (130 kilometers) from east to west and 17 miles (27 kilometers) from north to south. Engineers calculate the spacecraft will have a 99-percent chance of landing within that ellipse, if targeted for the center.

Elysium is one of three areas on Mars that meet two basic engineering constraints for InSight. One requirement is being close enough to the equator for the lander's solar array to have adequate power at all times of the year. Also, the elevation must be low enough to have sufficient atmosphere above the site for a safe landing.  The spacecraft will use the atmosphere for deceleration during descent.

All four semifinalist sites, as well as the rest of the 22 candidate sites studied, are in Elysium Planitia. The only other two areas of Mars meeting the requirements of being near the equator at low elevation, Isidis Planitia and Valles Marineris, are too rocky and windy. Valles Marineris also lacks any swath of flat ground large enough for a safe landing.

InSight also needs penetrable ground, so it can deploy a heat-flow probe that will hammer itself 3 yards to 5 yards into the surface to monitor heat coming fr om the planet's interior. This tool can penetrate through broken-up surface material or soil, but could be foiled by solid bedrock or large rocks.

"For this mission, we needed to look below the surface to evaluate candidate landing sites," Golombek said.

InSight's heat probe must penetrate the ground to the needed depth, so scientists studied Mars Reconnaissance Orbiter images of large rocks near Martian craters formed by asteroid impacts. Impacts excavate rocks fr om the subsurface, so by looking in the area surrounding craters, the scientists could tell if the subsurface would have probe-blocking rocks lurking beneath the soil surface.

InSight also will deploy a seismometer on the surface and will use its radio for scientific measurements.

И где же эти эллипсы? Нарисовали кружочек диаметром ок. 180 км с центром ок. 3N:136E - и всё. А между тем чуть правее, на 5N:150E, целое "замерзшее море"!

Я вот все думаю, почему ни один из марсоходов не снарядили закладными взрывными устройствами? Ведь как было бы хорошо, к примеру, в подобном месте, оставить небольшую мину, отъехать подорвать и вот тебе -  вскрытие пород :)

И комплект сейсмодатчиков. Может даже многоразовых... Уже любопытно было бы...
И мы пошли за так, на четвертак, за ради бога
В обход и напролом и просто пылью по лучу...
 
А если нам запустить "Протоном" тяжёлый зонд-ударник? Мегаимпактор а-ля Дип Импакт? Или Мега-Луна-2. Я серьёзно - "Протон" нам разгонит этот искусственный метеорит, а потом он врежется в Марс в нужное место в нужное время. Для уточнения параметров столкновения можно установить камеру и радар с прямой трансляцией. + наблюдение с орбитальных зондов. Дёшево и сердито!
