Hopefully they might be dissuaded from the crashing part.
MCC image, taken on September 03, 2015 at an altitude of 6144 km with a resolution of 320 m, shows an intermediate sized shield volcano known as Tharsis Tholus. It is located in the eastern Tharsis region of the planet Mars. The Tharsis Tholus is dome-shaped with flank slopes ranging from less than 1° near the summit to up to 16° at the base. The average flank slope is 10°, making it one of the steepest volcanoes on Mars. The volcano rises to an elevation of about 9 km (5.5 miles).

Far safer to leave it in orbit after passivization.
AIUI, burn up in the atmosphere is considered a good sterilization method.

Henry Crater -IMAGE FROM MCCHenry Crater is a large crater in the Arabia quadrangle of Mars, located at 10.9° north latitude and 336.7° west longitude. It is 171 kilometers (106 mi) in diameter and was named after the brothers Paul-Pierre Henry and Mathieu-Prosper Henry, both of whom were French telescope makers and astronomers.Henry Crater has a large mound in its center that shows layers in certain parts. The layers can be a few meters thick or tens of meters thick. It is believed that the regular pattern of layers in Arabia is connected to the regular way in which the rotational axis of Mars changes.This image was taken on Aug 29, 2015 at an altitude of 5800 km with a resolution of 301 m by MCC.

Arabia Terra-image from Mars Color CameraArabia Terra is a large upland region in the north of Mars located mostly in the Arabia quadrangle.Arabia Terra is a large upland region in the north of Mars located mostly in the Arabia quadrangle. It is densely cratered and heavily eroded. This battered topography indicates great age, and Arabia Terra is presumed to be one of the oldest terrains on the planet. Gill Crater is an impact crater in the Arabia quadrangle of Mars.This image is taken by Mars Color Camera on 22nd October 2015 at an altitude of 14893 km with a resolution of 774 m.
Data from MOM Scientific InstrumentsThe first important operation carried out in the Martian phase was to operate all the five payloads (scientific instruments). All the payloads have been operated and tested successfully. Mars Orbiter Spacecraft is now circling the Red Planet in an orbit with a periareion of 311 km and an apoareion of 71,311 km. All the five payloads of MOM are in good health and continue to provide data.The Mars Colour Camera (MCC) has acquired more than 440 images so far. A Mars Atlas has been released and the same is made available on ISRO website. MCC has achieved almost all the intended goals. It is planned to study temporal variations of features in comparison with older images of the past from other spacecraft and its own images.The MENCA payload has observed several atomic species in its neutral mass spectrum. Specific studies of altitude variation of theses were made from the data in Dec. 2014, when the observations were made near periareion at low altitude and conditions were favourable. Prominent atomic species noted are with mass units 28, 44; trends with varying altitudes were also discussed. These results will be consolidated for a publication in the near future. The results are also being compared where possible, with the MAVEN data.The analysis of the TIS payload was also presented during the meet. Since the instrument has an uncooled bolometer as detector, good sensitivity is obtained only during higher temperatures and therefore requires appropriate conditions for observations. This instrument found the variation in temperature during dust storms to be lowered by 10-15 degrees, which was verified using data from Earth based observations also.The LAP payload had 80 operations so far and hydrogen Lyman Alpha intensity is estimated as a function of altitude. Calibrations with UV stars are to be done, for which the payload team will work out the sensitivity. Besides, the joint analysis of data using multiple payloads was also presented.The dust patterns around high altitude regions and in Valles (Valleys) were studied and mean height of dust layer was estimated to be ~1.5 km. Albedo using the 1.65 micron studies of the reference channel of Methane sensor for Mars (MSM) was also estimated. Atmospheric optical depth and its variation was also estimated.Additionally, joint morphological studies using MCC and the high resolution mineralogical data with the NASA CRISM data was also presented, which enables the identification of different compounds like sulphates and ferrous based compounds.During the meet, a presentation on future challenges and mission plan for the same was also made. Some of the points covered wereLong eclipses of ~500 minutes expected in Feb 2017 due to eclipses occurring in apoareion compared to the <100 minute eclipses which were near periareion so far ; Maneuvering plans for payload operations with appropriate settings for the reaction wheelsFurther imaging of the Martian Satellite DeimosOpportunities for imaging North pole and other specific targets of MarsThis was followed by presentations on individual payloads, and joint activities with NASA undertaken so farRegular health checks and orbit determination of MOM is also being carried out. The Spacecraft is in good health and continues to work as expected. Scientific analysis of the data being received from the Mars Orbiter spacecraft is in progress.

Sharonov crater-Image from Mars OrbiterSharonov crater is an impact crater of size 100 km located in Lunae Palus Quadrangle of Mars. Sharonov is located within the outflow channel system Kasei valles (Kasei mean Mars in Japanese language), a giant system of canyons is Mare Acidalium and Lunae Palus Quadrangle. This huge system is 300 miles wide in some places. In contrast, Earth's Grand Canyon is only 18 miles wide. This image is taken by Mars colour camera on 13th November at an altitude of 24023 km with a resolution of 1.2 km
Olympus Mons - Picture from Mars OrbiterOlympus Mons is the largest volcano in the solar system which is present on planet Mars. The altitude of Olympus Mons is nearly three times the altitude of the largest peak on Earth, Mt.Everest.Tharsis volcanoes are Arsia Mons, Pavonis Mons and Ascraeus Mons. Tharsis Montes are product of volcanism and they are associated with tectonic processes which caused extensive crustal deformation in this area.Water vapor clouds are seen around mons top which is a usual phenomenon during this season in Mars. This image is taken by MCC on November 27, 2015 at an altitude of 32,282 km with a resolution of 1679 m
Mojave Crater-Image From MCCMojave is a ~3 million year old impact crater (58 km in diameter) and is located in Oxia Palus quadrangle of Mars. It has land forms that are similar to southwest American Mojave desert on Earth. MCC has taken this image on August 4, 2015 at an altitude of 2987 km with a resolution of 155 m
