Mars Orbiter Mission

The Mars Orbiter Mission (MOM), unofficially known as Mangalyaan (Sanskrit: Maṅgala 'Mars', Yāna 'Craft, Vehicle'), was a space probe orbiting Mars since 24 September 2014. It was launched on 5 November 2013 by the Indian Space Research Organisation (ISRO). It was India's first interplanetary mission and it made ISRO the fourth space agency to achieve Mars orbit, after Roscosmos, NASA, and the European Space Agency. It made India the first Asian nation to reach the Martian orbit and the first nation in the world to do so on its maiden attempt. It also made India the third nation to orbit another planet after the United States and the Soviet Union.

The Mars Orbiter Mission probe lifted off from the First Launch Pad at Satish Dhawan Space Centre (Sriharikota Range SHAR), Andhra Pradesh, using a Polar Satellite Launch Vehicle (PSLV) rocket C25 at 09:08 (UTC) on 5 November 2013. The launch window was approximately 20 days long and started on 28 October 2013. The MOM probe spent about a month in Earth orbit, where it made a series of seven apogee-raising orbital manœuvres before trans-Mars injection on 30 November 2013 (UTC). After a 298-day transit to Mars, it was put into Mars orbit on 24 September 2014.

The mission was a technology demonstrator project to develop the technologies for designing, planning, management, and operations of an interplanetary mission. It carried five scientific instruments. The spacecraft was monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from the Indian Deep Space Network (IDSN) antennae at Bengaluru, Karnataka.

On 2 October 2022, it was reported that the orbiter had irrecoverably lost communications with Earth after entering a seven-hour eclipse period in April 2022 that it was not designed to survive. The following day, ISRO released a statement that all attempts to revive MOM had failed and officially declared it dead, citing the loss of fuel and battery power to the probe's instruments.

History
In November 2008, the first public acknowledgement of an uncrewed mission to Mars was announced by then-ISRO chairman G. Madhavan Nair. The MOM mission concept began with a feasibility study in 2010 by the Indian Institute of Space Science and Technology after the launch of lunar satellite Chandrayaan-1 in 2008. Prime Minister Manmohan Singh approved the project on 3 August 2012, after the Indian Space Research Organisation completed inr 1250000000 of required studies for the orbiter. The total project cost may be up to inr 4540000000. The satellite costs inr 1530000000 and the rest of the budget has been attributed to ground stations and relay upgrades that will be used for other ISRO projects.

The space agency had planned the launch on 28 October 2013 but was postponed to 5 November following the delay in ISRO's spacecraft tracking ships to take up pre-determined positions due to poor weather in the Pacific Ocean. Launch opportunities for a fuel-saving Hohmann transfer orbit occur every 26 months, in this case the next two would be in 2016 and 2018.

Assembly of the PSLV-XL launch vehicle, designated C25, started on 5 August 2013. The mounting of the five scientific instruments was completed at Indian Space Research Organisation Satellite Centre, Bengaluru, and the finished spacecraft was shipped to Sriharikota on 2 October 2013 for integration to the PSLV-XL launch vehicle. The satellite's development was fast-tracked and completed in a record 15 months, partly due to using reconfigured Chandrayaan-2 orbiter bus. Despite the US federal government shutdown, NASA reaffirmed on 5 October 2013 it would provide communications and navigation support to the mission "with their Deep Space Network facilities.". During a meeting on 30 September 2014, NASA and ISRO officials signed an agreement to establish a pathway for future joint missions to explore Mars. One of the working group's objectives will be to explore potential coordinated observations and science analysis between the MAVEN orbiter and MOM, as well as other current and future Mars missions.

On 2 October 2022, it was reported that the orbiter had irrecoverably lost communications with Earth after entering long eclipse period in April 2022 that it was not designed to survive. At the time of communications loss it was unknown whether the probe had lost power or inadvertently realigned its Earth-facing antenna during automatic maneuvers.

Cost
The total cost of the mission was approximately ₹450 Crore (US$73 million), making it the least-expensive Mars mission to date. The low cost of the mission was ascribed by ISRO chairman K. Radhakrishnan to various factors, including a "modular approach", few ground tests and long working days (18 to 20 hours) for scientists. BBC's Jonathan Amos specified lower worker costs, home-grown technologies, simpler design, and a significantly less complicated payload than NASA's MAVEN. Prime Minister Modi said that the mission cost less than the film Gravity.

Mission objectives
The primary objective of the mission is to develop the technologies required for designing, planning, management and operations of an interplanetary mission. The secondary objective is to explore Mars' surface features, morphology, mineralogy and Martian atmosphere using indigenous scientific instruments.

The main objectives are to develop the technologies required for designing, planning, management and operations of an interplanetary mission comprising the following major tasks:


 * Orbit manoeuvres to transfer the spacecraft from Earth-centred orbit to heliocentric trajectory and finally, capture into Martian orbit
 * Development of force models and algorithms for orbit and attitude (orientation) computations and analysis
 * Navigation in all phases
 * Maintain the spacecraft in all phases of the mission
 * Meeting power, communications, thermal and payload operation requirements
 * Incorporate autonomous features to handle contingency situations

Scientific objectives
The scientific objectives deal with the following major aspects:


 * Exploration of Mars surface features by studying the morphology, topography and mineralogy
 * Study the constituents of Martian atmosphere including methane and using remote sensing techniques
 * Study the dynamics of the upper atmosphere of Mars, effects of solar wind and radiation and the escape of volatiles to outer space

The mission would also provide multiple opportunities to observe the Martian moon Phobos and also offer an opportunity to identify and re-estimate the orbits of asteroids seen during the Martian Transfer Trajectory. The spacecraft also provided the first views ever of the far side of Martian Moon Deimos.

Studies
In May–June 2015 Indian scientists got an opportunity to study the Solar Corona during the Mars conjunction when earth and Mars are on the opposite sides of the sun. During this period the S band waves emitted by MOM were transmitted through the Solar Corona that extends millions of kms into space. This event helped scientists study the Solar surface and regions where temperature changed abruptly.

Spacecraft design

 * Mass: The lift-off mass was 1337.2 kg, including 852 kg of propellant.
 * Bus: The spacecraft's bus is a modified I-1 K structure and propulsion hardware configuration, similar to Chandrayaan-1, India's lunar orbiter that operated from 2008 to 2009, with specific improvements and upgrades needed for a Mars mission. The satellite structure is constructed of an aluminium and composite fibre reinforced plastic (CFRP) sandwich construction.
 * Power: Electric power is generated by three solar array panels of 1.8 x each (7.56 m2 total), for a maximum of 840 watts of power generation in Mars orbit. Electricity is stored in a 36 Ah Lithium-ion battery.
 * Propulsion: A liquid fuel engine with a thrust of 440 N is used for orbit raising and insertion into Mars orbit. The orbiter also has eight 22 N thrusters for attitude control (orientation). Its propellant mass at launch was 852 kg.
 * Attitude and Orbit Control System: Maneuvering system that includes electronics with a MAR31750 processor, two star sensors, a solar panel Sun sensor, a coarse analog Sun sensor, four reaction wheels, and the primary propulsion system.
 * Antennae: Low gain antenna, mid gain antenna, and high gain antenna.

Scientific instruments
The 15 kg scientific payload consists of five instruments:

Telemetry and command
The ISRO Telemetry, Tracking and Command Network performed navigation and tracking operations for the launch with ground stations at Sriharikota and Port Blair in India, Brunei and Biak in Indonesia, and after the spacecraft's apogee became more than 100,000 km, an 18 m and a 32 m diameter antenna of the Indian Deep Space Network were utilised. The 18 m dish antenna was used for communication with the craft until April 2014, after which the larger 32 m antenna was used. NASA's Deep Space Network is providing position data through its three stations located in Canberra, Madrid and Goldstone on the US West Coast during the non-visible period of ISRO's network. The South African National Space Agency's (SANSA) Hartebeesthoek (HBK) ground station is also providing satellite tracking, telemetry and command services.

Communications
Communications are handled by two 230-watt TWTAs and two coherent transponders. The antenna array consists of a low-gain antenna, a medium-gain antenna and a high-gain antenna. The high-gain antenna system is based on a single 2.2 m reflector illuminated by a feed at S-band. It is used to transmit and receive the telemetry, tracking, commanding and data to and from the Indian Deep Space Network.

Launch
ISRO originally intended to launch MOM with its Geosynchronous Satellite Launch Vehicle (GSLV), but the GSLV failed twice in 2010 and still had issues with its cryogenic engine. Waiting for the new batch of rockets would have delayed the MOM for at least three years, so ISRO opted to switch to the less-powerful Polar Satellite Launch Vehicle (PSLV). Since it was not powerful enough to place MOM on a direct-to-Mars trajectory, the spacecraft was launched into a highly elliptical Earth orbit and used its own thrusters over multiple perigee burns (to take advantage of the Oberth effect) to place itself on a trans-Mars trajectory.

On 19 October 2013, ISRO chairman K. Radhakrishnan announced that the launch had to be postponed by a week for 5 November 2013 due to a delay of a crucial telemetry ship reaching Fiji. The launch was rescheduled. ISRO's PSLV-XL placed the satellite into Earth orbit at 09:50 UTC on 5 November 2013, with a perigee of 264.1 km, an apogee of 23903.6 km, and inclination of 19.20 degrees, with both the antenna and all three sections of the solar panel arrays deployed. During the first three orbit raising operations, ISRO progressively tested the spacecraft systems.

The orbiter's dry mass is 482.5 kg and it carried 852 kg of fuel at launch. Its main engine, a derivative of the system used on India's communications satellites, uses the bipropellant combination monomethylhydrazine and dinitrogen tetroxide to achieve the thrust necessary for escape velocity from Earth. It was also used to slow down the probe for Mars orbit insertion and, subsequently, for orbit corrections.

Models used for MOM:

Orbit raising manoeuvres
Several orbit raising operations were conducted from the Spacecraft Control Centre (SCC) at the ISRO Telemetry, Tracking and Command Network (ISTRAC) at Peenya, Bengaluru on 6, 7, 8, 10, 12 and 16 November by using the spacecraft's on-board propulsion system and a series of perigee burns. The first three of the five planned orbit raising manoeuvres were completed with nominal results, while the fourth was only partially successful. However, a subsequent supplementary manoeuvre raised the orbit to the intended altitude aimed for in the original fourth manoeuvre. A total of six burns were completed while the spacecraft remained in Earth orbit, with a seventh burn conducted on 30 November to insert MOM into a heliocentric orbit for its transit to Mars.

The first orbit-raising manoeuvre was performed on 6 November 2013 at 19:47 UTC when the spacecraft's 440 N liquid engine was fired for 416 seconds. With this engine firing, the spacecraft's apogee was raised to 28825 km, with a perigee of 252 km.

The second orbit raising manoeuvre was performed on 7 November 2013 at 20:48 UTC, with a burn time of 570.6 seconds resulting in an apogee of 40186 km.

The third orbit raising manoeuvre was performed on 8 November 2013 at 20:40 UTC, with a burn time of 707 seconds, resulting in an apogee of 71636 km.

The fourth orbit raising manoeuvre, starting at 20:36 UTC on 10 November 2013, imparted a delta-v of 35 m/s to the spacecraft instead of the planned 135 m/s as a result of underburn by the motor. Because of this, the apogee was boosted to 78276 km instead of the planned 100000 km. When testing the redundancies built-in for the propulsion system, the flow to the liquid engine stopped, with consequent reduction in incremental velocity. During the fourth orbit burn, the primary and redundant coils of the solenoid flow control valve of 440 newton liquid engine and logic for thrust augmentation by the attitude control thrusters were being tested. When both primary and redundant coils were energised together during the planned modes, the flow to the liquid engine stopped. Operating both the coils simultaneously is not possible for future operations, however they could be operated independently of each other, in sequence.

As a result of the fourth planned burn coming up short, an additional unscheduled burn was performed on 12 November 2013 that increased the apogee to 118642 km, a slightly higher altitude than originally intended in the fourth manoeuvre. The apogee was raised to 192874 km on 15 November 2013, 19:57 UTC in the final orbit raising manoeuvre.

Trans-Mars injection
On 30 November 2013 at 19:19 UTC, a 23-minute engine firing initiated the transfer of MOM away from Earth orbit and on heliocentric orbit toward Mars. The probe travelled a distance of 780000000 km to reach Mars.

Trajectory correction maneuvers
Four trajectory corrections were originally planned, but only three were carried out. The first trajectory correction manoeuvre (TCM) was carried out on 11 December 2013 at 01:00 UTC by firing the 22 N thrusters for a duration of 40.5 seconds. After this event, MOM was following the designed trajectory so closely that the trajectory correction manoeuvre planned in April 2014 was not required. The second trajectory correction manoeuvre was performed on 11 June 2014 at 11:00 UTC by firing the spacecraft's 22 newton thrusters for 16 seconds. The third planned trajectory correction manoeuvre was postponed, due to the orbiter's trajectory closely matching the planned trajectory. The third trajectory correction was also a deceleration test 3.9 seconds long on 22 September 2014.

Mars orbit insertion
The plan was for an insertion into Mars orbit on 24 September 2014, approximately 2 days after the arrival of NASA's MAVEN orbiter. The 440-newton liquid apogee motor was test fired on 22 September at 09:00 UTC for 3.968 seconds, about 41 hours before actual orbit insertion.

After these events, the spacecraft performed a reverse manoeuvre to reorient from its deceleration burn and entered Martian orbit.

Observation of suprathermal argon in exosphere
The Mars Exospheric Neutral Composition Analyser (MENCA) reported altitude profiles of argon-40 in the Martian exosphere from four orbits during December 2014 when the periapsis of the spacecraft was lowest. The upperlimit of the argon number density corresponding to this period is almost 5 x 105/cm3 at an altitude of 250 km and the typical scale height is around 16 km corresponding to an exospheric temperature of around 275 K. However, on two orbits, the scale height over this altitude region is found to increase significantly making the effective temperature greater than 400 K. The observations of Neutral Gas and Ion Mass Spectrometer (NGIMS) onboard the MAVEN also indicate that the change in slope in argon density occurs near the upper exosphere of around 230–260 km. These observations indicate significant suprathermal populations of carbon dioxide and argon in the Martian exosphere.

Global apparent short wave infrared albedo mapping
Global apparent short wave infrared (SWIR) albedo mapping of Mars was executed based on data acquired from the Methane Sensor for Mars (MSM) payload. The instrument is a differential radiometer in SWIR region of spectrum that measures reflected solar radiance in two SWIR (1.64 to 1.66 μm) channels. The first one is a methane channel which measures the absorption by methane and second one is a no absorption channel (reference channel). The reference channel data acquired from October 2014 to February 2015 was used for apparent SWIR albedo mapping. Data less than one degree of the limb of the planet was discarded to avoid atmospheric limb brightening and to ensure that the field of view was entirely on the planet. Data with incidence and zolar zenith angle greater than 60° was also discarded to reduce atmospheric effects.

The bright regions having an albedo greater than 0.4 are mainly localised over the Tharsis plateau, Arabia Terra, and Elysium Planitia and generally represent surface covered by dust while the low albedo of less than 0.15 are mainly localised over Syrtis Major Planum, Daedalia Planum, Valles Marineris and Acidalia Planitia. The low albedo is associated with dark surfaces having volcanic rock basalt as surface expostures. Weekly mean apparent albedo data over Syrtis Major Planum was recorded in a period of solar longitudes 205 to 282 (October 2014) during which dust activities are significant. A surge in mean albedo from the usual 0.2 to an erratically higher near 0.4 was recorded on solar longitude 225 which was possibly due to the local injection of dust into atmosphere. This matches with a similar albedo spike in the region during solar longitude of 280-290 recorded by Viking IRTM.

Neutral composition of evening time exosphere
The Mars Exosphere Neutral Composition Analyser (MENCA) during 18-29 December 2014 provided altitude profiles of three major constituents; carbon dioxide (amu 44), nitrogen molecule & carbon monoxide (amu 28) and atomic oxygen (amu 16) in the Martian exosphere. This measurents were taken from four orbits which were closest to Mars with a periapsis which varied from 262 - 265 km during the evening time or close to sunset terminator hours to attain moderate solar activity conditions.

During evening hours the carbon dioxide density changes from 3.5 × 107 cm to 1.5 × 105/cm3 for an altitude change of 100 km in the exosphere. The number density of amu 28 is comparable to that of carbon dioxide (amu 44) at lower altitudes and exceeds above 275 km. The factor becomes almost 10 at 375 km. The atomic oxygen number density exceeds that of carbon dioxide above 270 km. At 335 km, this difference becomes a factor of 10, above which atomic oxygen far exceeds the abundance of carbon dioxide. The transition from carbon dioxide to atomic oxygen dominant exosphere is an important indicator of the solar EUV forcing. The mean exospheric temperature derived using the scale height values estimated from the observed partial pressure variation in the three mass channels is 271 ± 5 K. These first observations corresponding to the Martian evening hours is expected to provide constraints data to the thermal escape models.

Radio occultation experiment on solar corona
Radio occulation experiments were performed using S-band downlink signals from the spacecraft during the May-June 2015 (post-maxima of solar cycle 24) period when the Sun was between Earth and Mars along a line in the same elliptical plane. The downlink signals from the spacecraft of frequency 2.29 GHz passed through the solar coronal region at solar offset distances between 4-20 solar radius.

The experiment was conducted in a closed-loop one-way format at a sampling frequency of one hertz and the occultation geometry was such that the proximate ray path from the spacecraft to Earth covered a range of 5−39 degree heliolaltitudes. From observations with radio signals from the spacecraft, it is found that the turbulence power spectrum at larger heliocentric distances greater than 10 (18.17  on 28 May), the curve steepens with a spectral index of around 0.6−0.8. For smaller heliocentric distances of less than 10 (5.33  on 10 June), it displays flattening in lower-frequency regions with a spectral index of around 0.2−0.4, which corresponds to a solar wind acceleration region. A complimentary observation is that the higher-heliolatitude spectra appear to be flatter than lower-heliolatitude spectra.

Atmospheric optical depth in the Valles Marineris
Stereo images of Valles Marineris acquired by Mars Colour Camera (MCC) payload along with the co-regisered MOLA Digital Elevation Map (DEM) were used to calculate atmospheric optical depth (AOD) over northern and southern walls of Valles Marineris. On northern wall ranging from 62°W to 68°W, the red channel of MCC measured an AOD of 1.7 near the bottom of the valley and decreases monotonically to about 1.0 near the top, while the green channel measures an AOD of around 2.1 and similarly decreases monotonically with increasing altitude. Both measurements shows a clear relation that can be well fitted with an exponential curve. The calculated scale height of AOD equals to 14.08 km and 11.24 km for red and green channels respectively.

The red channel AOD measurement on the southern wall of Valles Marineris ranging from 62°W to 68°W remains nearly steady from 1.75 in the bottom of the valley to 1.85 near to the top and does not show a monotonic decline of AOD with altitude. From the AOD map overlaid on MCC image draped on MOLA DEM, it is clear that there is a mountain-like structure along the southern walls of the valley, which is expected to cause the creation of banner clouds in the lee side of the mountain or lee wave clouds. The AOD variation with altitude along the southern wall between the longitudes 57°W to 62°W where mountain structures are not present shows a normal monotonic decrease. This further supports the existence of lee wave clouds on the southern wall of Valles Marineris around 65°W.

Status
The orbit insertion put MOM in a highly elliptical orbit around Mars, as planned, with a period of 72 hours 51 minutes 51 seconds, a periapsis of 421.7 km and apoapsis of 76993.6 km. At the end of the orbit insertion, MOM was left with 40 kg of fuel on board, more than the 20 kg necessary for a six-month mission.

On 28 September 2014, MOM controllers published the spacecraft's first global view of Mars. The image was captured by the Mars Colour Camera (MCC).

On 7 October 2014, the ISRO altered MOM's orbit so as to move it behind Mars for comet Siding Spring's flyby of the planet on 19 October 2014. The spacecraft consumed 1.9 kg of fuel for the manoeuvre. As a result, MOM's apoapsis was reduced to 72000 km. After the comet passed by Mars, ISRO reported that MOM remained healthy.

On 4 March 2015, the ISRO reported that the MSM instrument was functioning normally and are studying Mars' albedo, the reflectivity of the planet's surface. The Mars Colour Camera was also returning new images of the Martian surface.

On 24 March 2015, MOM completed its initial six-month mission in orbit around Mars. ISRO extended the mission by an additional six months; the spacecraft has 37 kg of propellant remaining and all five of its scientific instruments are working properly. The orbiter can reportedly continue orbiting Mars for several years with its remaining propellant.

A 17-day communications blackout occurred from 6 to 22 June 2015 while Mars' orbit took it behind the Sun from Earth's view.

On 24 September 2015, ISRO released its Mars Atlas, a 120-page scientific atlas containing images and data from the Mars Orbiter Mission's first year in orbit.

In March 2016, the first science results of the mission were published in Geophysical Research Letters, presenting measurements obtained by the spacecraft's MENCA instrument of the Martian exosphere.

During 18 to 30 May 2016, a communication whiteout occurred with Earth coming directly between Sun and Mars. Due to high solar radiation, sending commands to spacecraft was avoided and payload operations were suspended.

On 17 January 2017, MOM's orbit was altered to avoid the impending eclipse season. With a burn of eight 22 N thrusters for 431 seconds, resulting in a velocity difference of 97.5 m/s using 20 kg of propellant (leaving 13 kg remaining), eclipses were avoided until September 2017. The battery is able to handle eclipses of up to 100 minutes.

On 19 May 2017, MOM reached 1,000 days (973 sols) in orbit around Mars. In that time, the spacecraft completed 388 orbits of the planet and relayed more than 715 images back to Earth. ISRO officials stated that it remains in good health.

On 24 September 2018, MOM completed 4 years in its orbit around Mars, although the designed mission life was only six months. Over these years, MOM's Mars Colour Camera has captured over 980 images that were released to the public. The probe is still in good health and continues to work nominally.

On 24 September 2019, MOM completed 5 years in orbit around Mars, sending 2 terabytes of imaging data, and had enough propellant to complete another year in orbit.

On 1 July 2020, MOM was able to capture a photo of the Mars satellite Phobos from 4200 km away.

On 18 July 2021 Mars Colour Camera (MCC) captured full disc image of Mars from an altitude of about 75,000 km with spatial resolution about 3.7 km.

In October 2022, ISRO admitted that it has lost the communication with MOM in April 2022, when it faced increasingly longer duration eclipses, including a seven-hour long eclipse that it was not designed to withstand. ISRO said the spacecraft was likely out of propellant and not recoverable.

Recognition


In 2014, China referred to India's successful Mars Orbiter Mission as the "Pride of Asia". The Mars Orbiter Mission team won US-based National Space Society's 2015 Space Pioneer Award in the science and engineering category. NSS said the award was given as the Indian agency successfully executed a Mars mission in its first attempt; and the spacecraft is in an elliptical orbit with a high apoapsis where, with its high resolution camera, it is taking full-disk colour imagery of Mars. Very few full disk images have ever been taken in the past, mostly on approach to the planet, as most imaging is done looking straight down in mapping mode. These images will aid planetary scientists.

An illustration of the Mars Orbiter Mission spacecraft is featured on the reverse of the ₹2,000 currency note of India.

An image taken by the Mars Orbiter Mission spacecraft was the cover photo of the November 2016 issue of National Geographic magazine, for their story "Mars: Race to the Red Planet".

Follow-up mission
ISRO plans to develop and launch a follow-up mission called Mars Orbiter Mission 2 (MOM-2 or Mangalyaan-2) with a greater scientific payload to Mars in 2024. The orbiter will use aerobraking to reduce apoapsis of its initial orbit and reach an altitude more suitable for scientific observation.
