Japan's H-IIA rocket is gearing up for its sixth and final launch of the year, set for a Saturday liftoff fr om the picturesque Tanegashima Space Center to send a pair of very different satellites into orbit, one to study changes of our planet over a long time scale while the other will descend and complete a mission orbiting on the edge of the atmosphere to help develop previously unused orbital real estate.

H-IIA is targeting a 22-minute launch window opening at 1:26:22 UTC on Saturday and will first be tasked with a direct ascent into an 800-Kilometer orbit fr om where the GCOM-C satellite will operate, joining Japan's Global Change Observation Mission that aims to study Earth's water, energy and carbon cycles over a period of over ten years to deliver relevant data for long-term climate assessments. The rocket's second stage will then show off its new multi-orbit mission capability by performing an additional two engine burns to descend in altitude before sending SLATS, the Super-Low Altitude Test Satellite, on its way to demonstrate the feasibility of operating a satellite between 200 and 300 Kilometers in altitude.

Saturday's H-IIA launch window opens just 61 seconds before the instantaneous launch opportunity comes for a Falcon 9 rocket launching out of California's Vandenberg Air Force Base (http://spaceflight101.com/falcon-9-iridium-next-flight-4/) with the next ten satellites joining the Iridium-NEXT communications constellation. Provided H-IIA launches at the top of its window and Falcon 9 makes its instantaneous window, these two missions are contenders for a new record for the shortest time ever between two orbital launches.

The current record goes all the way back to the dawn of the Space Age when, on August 18, 1960 a Thor-Agena and a Thor-Ablestar lifted off fr om Vandenberg and Florida's Cape Canaveral at 19:57:08 and 19:58 UTC. Unfortunately, the launch time for the latter is only known to the minute, leaving an uncertainty in the all-time record between 52 and 111 seconds. Nevertheless, avid space fans will be in need for dual screen viewing Friday night if these two launches occur just over a minute apart – a page with both webcasts is provided by Spaceflight101 here (http://spaceflight101.com/h-iia-gcom-c1/dual-launch-coverage-falcon-9-h-iia/).

For H-IIA, this mission will close the rocket's busiest year to date, having already broken its previous record of four flights in a calendar year. Half of H-IIA's missions in 2017 were dedicated to lifting three Quasi-Zenith Satellites to complete the QZS System designed to improve GPS navigation in Japan's urban canyons and enabling high-accuracy GPS exploitation in a number of areas including aviation and mapping. The other H-IIA missions performed so far this year lifted the DSN-2 communications satellite for the Japanese government and armed forces and the IGS-Radar 5 reconnaissance satellite.

Saturday's mission will be headed to Low Earth Orbit and demonstrate a new multi-orbit capability as the GCOM-C1 and SLATS satellites target two different orbital regimes.

GCOM-C1, the Global Change Observation Mission for Climate, is part of the GCOM project operated by the Japan Aerospace Exploration Agency to collect surface and atmospheric parameters over an extended observation period to contribute to climate research. GCOM-C, also known as Shikisai, joins the GCOM-W1 satellite (Shizuku) launched in 2012.

Under the two-satellite architecture, GCOM-W hosts a high-fidelity microwave radiometer to collect data on Earth's water and energy cycles while GCOM-C contributes surface and atmospheric measurements of various parameters through the use of a 19-channel imaging payload, providing insight into Earth's carbon cycle and radiation budget. Data fr om the GCOM project is employed in a twofold fashion – long-term records established by multiple generations of satellites will feed into numerical climate models while the constantly upd ated data from the satellites finds application in operational areas like weather forecasting and disaster mitigation.

GCOM Instrument – Image: JAXA

The 1,950-Kilogram GCOM-C satellite hosts a single instrument known as the Second-Generation Global Imager (SGLI) – a multi-channel imaging instrument covering 19 spectral bands from the UV spectrum over the visible & near-infrared wavelengths to the thermal infrared spectrum with varying ground resolutions between 250 and 1,000 meters and polarization sensitivity.

Combining a pushbroom sensor for VNIR imaging and a whiskbroom scanning instrument for the infrared measurements, GCOM-C1 will deliver a complete picture of Earth every two to three days and its high image resolution will enable anthropogenic climate effects to be assessed over extended periods.

Riding shotgun underneath the GCOM-C1 satellite is the Super-Low Altitude Test Satellite SLATS, setting out on a mission orbiting on the edge of the atmosphere wh ere the satellite will have to actively combat air resistance to avoid dropping out of orbit.

SLATS – Image: JAXA

Orbital altitudes between 200 and 300 Kilometers are rarely used given the high-drag environment in the upper reaches of Earth's atmosphere, but offer a number of advantages for scientific and operational missions arising from the close distance to Earth's surface.

Orbiting closer to Earth will enhance the resolution of imaging instruments while radars or LIDARs would be able to accomplish their measurements at much lower transmit power. In addition to operational benefits, the Super-Low Earth Orbit regime is also of interest to the scientific community as a rarely explored atmospheric region.

In fact, the lower thermosphere, extending from 90 to 380 Kilometers, is the least explored layer of the atmosphere even though it plays an important role in energy-exchange processes between the dense gaseous atmosphere and the higher layers wh ere energetic particles roam.

(https://img.novosti-kosmonavtiki.ru/152869.jpg) (http://spaceflight101.com/h-iia-gcom-c1/wp-content/uploads/sites/199/2017/12/a028a36eaf582803f800985823f29bcb.jpg)
SLATS during Testing – Photo: JAXA

Exploration of this region is difficult since remote sensing instruments looking from the ground up or watching down from satellites in higher orbits are only sensitive enough to capture vertical profiles from the lower atmosphere up to around 100 Kilometers. This would mean that the only way of exploring this vital part of Earth's atmosphere is through in-situ measurements – considered a difficult endeavor due to the atmospheric density at these altitudes which would bring a satellite to a fiery re-entry within a period of days if it can not actively counter drag to hold its altitude.

The 400-Kilogram SLATS satellite aims to demonstrate a platform that would enable extended operations at altitudes of 250 Kilometers and less for commercial and scientific exploitation. This will be possible through the use of a hybrid propulsion system featuring chemical thrusters and ion engines to be able to accomplish fast orbital changes using the traditional thrusters and long thrust phases for drag compensation with the ion engine.

After completing checkouts at a safe altitude, SLATS is planned to spiral down to 250 Kilometers and enter its orbit-keeping mode using the ion thruster. On a weekly basis, the satellite will reduce its altitude by another ten Kilometers until reaching 220 Kilometers wh ere SLATS will operate for two months. An extended mission at 180 Kilometers will see the satellite use its ion thruster at full duty cycle and the chemical thrusters joining in to help keep it in orbit.

SLATS will demonstrate the increase in spatial resolution possible from Super Low Earth Orbit by using an inexpensive imaging system while a materials science payload will study the effects of atomic oxygen on different samples to inform designers of future satellites operating at altitudes of 300km and less.

To send GCOM-C1 and SLATS into different orbits, H-IIA will demonstrate its new multi-orbit injection capability that builds on upgrades inaugurated on the rocket's second stage on H-IIA Flight 29 in 2015 that added modifications to allow for extended coast and multi-burn missions.

These features were first used for Geotransfer missions with extended coast phase but can also be applied for missions aiming for two or more distinct orbits, adding to H-IIA's repertoire and opening the launcher for competing in the growing LEO launch business by offering ride-share missions to different orbits.

Gearing up for launch, the 53-meter tall H-IIA is expected emerge from its Vehicle Assembly Building at 11:30 UTC on Friday, covering the first 500 meters toward orbit to be centered on the sea-side launch pad for power-up and checkouts. Propellant loading is expected to pick up seven hours and 45 minutes before launch to fill the two-stage rocket with 120 metric tons of -183°C Liquid Oxygen and -253°C Liquid Hydrogen. Extensive testing continues once the vehicle is fueled to clear the way for the computer-controlled countdown sequence kicking in at X-4.5 minutes.

Once in the hands of ground and onboard computers, H-IIA will go through the final preparatory steps, notably the pressurization of its four tanks, the transition to internal power and the activation of the Flight Control System. H-IIA will begin breathing fire at X-5.2 seconds when the LE-7A engine will start its ignition sequence to soar to a thrust of nearly 100 metric ton force under close watch by the rocket's flight computers.

Upon completion of engine monitoring, when clocks strike zero, H-IIA will fire up the twin boosters and leap off the pad with a total thrust of 600 metric-ton-force.

H-IIA will climb vertically for only a handful of seconds before initiating its pitch and roll program to enter a dogleg trajectory – initially flying south-east to depart Tanegashima and clear the Philippines to avoid frequented fishing areas so that its boosters and fairing drop into clear areas of the Pacific. In the later portion of the first stage burn, H-IIA will make a right hand turn to transition onto a heading to south-south-west in order to reach the desired orbital inclination of 98.7 degrees.

The twin boosters, each burning 65 metric tons of propellant, will burn out 91 seconds into the flight after helping accelerate the vehicle to 1.4 Kilometers per second. They will drop away 17 seconds later when H-IIA will have reached an altitude of 56 Kilometers.

With the 15-meter boosters swinging outward along their thrust struts, H-IIA will from then on rely on its LE-7A engine alone, burning 260 Kilograms of cryogenics per second to deliver 109,300-Kilogram force of thrust when heading into the upper reaches of Earth's atmosphere. The protective payload fairing will split open and drop away four minutes and five seconds into the flight when H-IIA crosses 167 Kilometers in altitude wh ere aerodynamic forces are no longer a danger to the delicate satellite structure.

Per the nominal mission plan, the first stage will shut down six minutes and 38 seconds into the flight, having boosted the vehicle to a speed of 3.6 Kilometers per second. Eight seconds later, the separation of the 37-meter long core stage will be commanded through loaded springs, expected some 380 Kilometers in altitude.

The second stage will fire up its LE-5B engine nine seconds after staging, generating 13,970kgf of thrust for a burn of eight minutes and 11 seconds – tasked with a direct ascent into an orbit of 788 by 806 Kilometers. Riding in the main passenger seat, GCOM-C1 is set for separation at X+16 minutes and 21 seconds upon which H-IIA will head into the second part of its mission to dispatch SLATS into a lower orbit.

The second stage will fire up for a retrograde burn of eight seconds 57 minutes and 46 seconds into the mission to hit the brakes and reduce the low point of the orbit to 470 Kilometers in altitude. 59 minutes and 55 seconds into the flight, Stage 2 will jettison the payload adapter that facilitated GCOM-C1 and reveal the SLATS satellite for another half lap of coasting before the second stage re-starts one hour, 45 minutes and 45 seconds into the flight to step on the brake again in order to se t up an orbit of 450 by 643 Kilometers for the separation of SLATS one hour and 48 minutes after liftoff.

EDITOR'S NOTE:  Upd ated at 0300 GMT Saturday (10:00 p.m. Friday) with confirmation of a successful launch.

Two research satellites to probe Earth's climate patterns and test ion engine technology to counter atmospheric drag in an unusual low-altitude orbit launched Saturday on top of a Japanese H-2A rocket.

The two Japanese-built spacecraft rocketed away from the Tanegashima Space Center in southern Japan at 0126:22 GMT Saturday (8:26:22 p.m. EST Friday) inside the H-2A's payload fairing.

Спойлер

Liftoff occurred at 10:26 a.m. Saturday Japan Standard Time.

Mounted on a dual-payload adapter fixture, the satellites were released into two distinct orbits a few hundred miles above Earth by the H-2A's upper stage.

First, the hydrogen-fueled launcher deployed the Shikisai climate monitoring satellite into a polar orbit around 500 miles (800 kilometers). Then the rocket's LE-5B upper stage engine reignited twice, targeting a lower altitude for separation of a technological demonstration satellite named Tsubame in an elliptical orbit between 280 and 400 miles (450-643 kilometers) over the planet.

Deployment of the 2.2-ton (2-metric ton) Shikisai satellite, also known as the Global Change Observation Mission-Climate (GCOM-C), occurred around 16 minutes after the H-2A rocket's liftoff from, a facility carved from the rocky coast of an island in southwestern Japan.

The 880-pound (400-kilogram) Tsubame payload, officially named the Super Low Altitude Test Satellite (SLATS), was released from the H-2A second stage at T+plus 1 hour, 48 minutes.

Flying on its 37th flight, the H-2A rocket headed south from Tanegashima and jettisoned two solid rocket boosters around two minutes into the flight.

The launcher's LE-7A main engine, consuming a cryogenic mix of liquid hydrogen and liquid oxygen, fired for about 6 minutes, 38 seconds.

The payload shroud covering the Shikisai and Tsubame satellites separated from rocket at T+plus 4 minutes, 5 seconds.

Once the first stage completed its job, the second stage took over the flight for three engine burns to inject the payloads into the mission's two target orbits.

The H-2A rocket blasted off from Japan 72 seconds before a SpaceX Falcon 9 rocket launched from Vandenberg Air Force Base, California.

The back-to-back liftoffs marked the shortest time between two orbital launch attempts since the dawn of the Space Age, according to Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who tracks global space activity.

The previous record for the shortest duration between two orbital launch attempts was set in December 1970, when a Soviet Kosmos 3M booster and a French Diamant-B rocket lifted off from Russia and French Guiana 4 minutes, 44 seconds, apart, McDowell said.

Saturday's successful mission was the sixth H-2A launch of the year, and the 37th straight success for Japan's H-2A/H-2B rocket family.

The Shikisai, or GCOM-C, mission is named for the word for colors in Japanese.

The satellite follows the Shizuku, or GCOM-W, mission launched by Japan in May 2012 to study Earth's water cycle.

The Shikisai satellite carries a wide-area global imaging instrument package — including a visible and near-infrared radiometer and an infrared scanner — to extend climate observations made by Japan's ADEOS 2 spacecraft, which succumbed to a power failure and ended its mission in 2003.

During its planned five-year mission, the climate monitoring observatory will make "surface and atmospheric measurements related to the carbon cycle and radiation budget, such as clouds, aerosols, ocean color, vegetation, and snow and ice," according to a fact sheet released by the Japan Aerospace Exploration Agency.

Scientists say Shikisai's observations will improve their understanding of climate change, and help numerical climate models predict future changes. The imager will also track phytoplankton, aerosol, and vegetation activity to map fisheries, monitor the transport of dust, and estimate crop yields, according to JAXA.

The smaller of the two satellites launched Saturday was named Tsubame, the Japanese word for swallow, after a public competition.

JAXA said Tsubame is "a perfect nickname for the thin, elongated satellite in super low orbit with a se t of solar array wings – what can describe it better than the small, familiar bird flying low?"

Tsubame will use aerodynamic drag to eventually drop into an orbit below 166 miles (268 kilometers), and an ion engine powered by electricity and xenon gas will maintain its altitude between 111 miles (180 kilometers) and 166 miles, counteracting air resistance from the thicker atmosphere at that height.

Designed with aerodynamic stability in mind, Tsubame was built to operate at least two years. The small spacecraft's ion engine produces thrust equivalent to the weight of a small coin, but it burns little fuel, allowing it to fire for weeks to months continuously.

"An orbit with an altitude lower than 300 kilometers (186 miles) is referred to as "super low orbit," and it is an unexplored region which has yet to be fully utilized by existing satellites," JAXA said in a fact sheet for the SLATS mission. "Satellites in a super low orbit will bring benefits such as higher resolution optical observation imagery, lower transmission power for active sensors, and cost reductions in satellite manufacturing and launches."

A European Space Agency satellite named GOCE flew in a super-low orbit with the aid of an ion engine to measure Earth's gravitational field and ocean circulation before running out of fuel in 2013 after a four-year mission.

The Tsubame satellite carries a camera to take pictures of Earth from orbit, and an experimental coating on the craft's thermal insulation to prevent damage from atomic oxygen, a gas present at the orbiting testbed's planned altitude. Atomic oxygen is known to damage the multi-layer insulation typically used on satellites, according to JAXA.

Japanese engineers want to know how the satellite responds to years of exposure to conditions at the mission's unusual operating altitude.

Completion of Critical Operations Phase, SHIKISAI and TSUBAME

December 24, 2017 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

JAXA received telemetry data fr om SHIKISAI and TSUBAME, confirming that their satellite attitude control system had transitioned to the steady state. Current status of both satellites is stable.

Subsequently, the following procedure occurred – power generation that supports the satellites' operation by the deployed solar array wings, ground communications and sound attitude control that maintains those operations. Combined by the completion of the series of other operations, such as powering up of the bus and mission equipment, the satellites have entered the state where they can be sustained in orbit. This concludes their critical operations phase*¹.

SHIKISAI and TSUBAME will move on to the next operations phase*², wh ere the functions of the satellites' onboard apparatus will be examined approximately in the next three-month period.

JAXA conveys deep appreciation for the support by all for the satellites' launch and tracking.


*¹ Critical operations phase: the phase that follows satellite's separation from a launch vehicle, solar array deployment, and powering up of instruments for the satellite's regular operations. The critical operations phase comes to an end at the start of the satellite's control mode for nominal operation.

*² Next operations phase: during this phase, the entire satellite, its observation/mission sensors and other onboard equipment are scrutinized.

Shikisai Data Stream Exploratory Measures Initiated for JAFIC

August 3, 2018 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency(JAXA)
General Incorporated Association
Japan Fisheries Information Service Center (JAFIC)

JAXA has undertaken the initial checkout and calibration*1 of Shikisai, originally known as Global Change Observation Mission-Climate (GCOM-C), to start the satellite-derived data stream service in December 2018. The operation of the Shikisai satellite has been nominal since the launch on December 23, 2017. On July 25, JAXA started the test stream service measures and has provided Japan Fisheries Information Service Center (JAFIC) with three types of nearly real time data including sea surface temperature.

Observation images fr om Shikisai can yield higher resolution images compared with other Earth observation satellites which provide data used for fisheries. Additionally, the satellite's multiple remote sensing, capable of simultaneous observation of ocean color and water temperature, will make the data applicable both to fisheries and marine research. Sea surface temperature in the fishing grounds and other detailed information pertaining to marine environment are expected to advance searching for productive fishing grounds. Data fr om Shikisai is also expected to enhance the monitoring of coastal environment, making it possible to observe seaweed beds, tidal flats, and algal blooms. It will contribute to the management of coastal marine resources and studies.

JAFIC will cooperate with JAXA in calibration and verification of the data by supplying on-site surface temperature and other data. The Center will also use the test data distribution to implement the service that provides information with stakeholders such as those engaging in commercial fishing and research institutions. JAXA will use on-site measurements for comparison provided by JAFIC and other sources and continuously ensure the ongoing checkout and calibration of the satellite.

In this image, the coolest waters appear in blue, and the warmest temperatures appear in red. Red circles are fishing spots for Japanese pilchard (Sardinops melanostictus). A band of waters at high temperature (in red) along the Japan current lies on the south of the fishing ground. Warm water (orange to green) veers north, countercurrent, off fr om the Japan current. Cold water (blue) is distributed along Kashima coast. This suggests fishing grounds are formed wh ere warm waters move north.

Tsubame Transition to Orbit Keeping Operations

March 18, 2019 (JST)

National Research and Development Agency
Japan Aerospace Exploration Agency (JAXA)

National Research and Exploration Agency Japan Aerospace Exploration Agency (JAXA) launched Tsubame*1, The Super Low Altitude Test Satellite, on December 23, 2017. The Tsubame satellite completed its orbit transfer phase and will transition on April 2 to the orbit keeping phase, powered by the ion engines.

Designed to open up the possibilities of satellite use in a super low orbit, Tsubame gradually lowered its altitude using atmospheric drag and the onboard gas jet and has been in good health.

The ensuing orbit keeping operation executes the descent in five stages, 271.5 kilometers, 250 kilometers, 240 kilometers, 230 kilometers, and 220 kilometers. Each altitude is sustained for some time. In an orbit at 180 kilometers, the target altitude, where there is significant atmospheric resistance, the gas jet is turned on in addition to the ion engines to withstand the drag. (See the images of the orbital maintenance operation profile)

On April 2 through May 2, the Tsubame satellite will be sustained at 271.5 kilometers, its recurrent orbit.*2 Stationary measuring is scheduled every day of the month-long period above the Tokyo metropolitan area at high resolution, one advantage that satellite operation in a super low orbit affords. Thereafter, the satellite gradually lowers its altitude and enters the orbit keeping operation through September. During this operation, data is to be acquired of the atmosphere and atomic oxygen in a super low altitude. Photographing by Small and High Resolution Optical Sensor (SHIROP) will also be experimented.

Tsubame three onboard mission instruments are:
(1) The Small and High Resolution Optical Sensor (SHIROP)
(2) The Optical Sensor (OPS)
(3) The Atomic Oxygen Monitor System (AMO) – comprising of the Atomic Oxygen Monitor (AOFS) and the Material Degradation Monitor (MDM)

*2: A satellite repeats its path, which is called a recurrent or sub-recurrent orbit. This orbit enables the satellite to observe the same area at regular intervals.

(1) The Small and High Resolution Optical Sensor (SHIROP)
19.4 kg and 20 cm in diameter, the SHIROP is a small optical sensor, less than 10-meter resolution, designed to demonstrate observations at super low altitudes. Compared to 30 cm in diameter and 2.5 meter resolution of the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) onboard Daichi, the Advanced Land Observing Satellite, launched on January 24, 2006, the SHIROP is smaller and has more sensitive resolution, as it observes in a super low orbit.
Below are the images captured by Tsubame on January 2.
On April 2 through May 2, the areas above Tokyo Station and Shinjyuku-gyoen including Akasaka Geihinkan and the New National Stadium will be observed. Atmospheric resistance and other factors may change the satellite's orbit. This may alter the measuring spots, too. Observations will proceed rain or shine, but clouds may prevent getting clear images on the ground.

New Dataset Release: GCOM-C/SGLI

JAXA GCOM-C (Global Change Observation Mission - Climate "SHIKISAI") satellite was launched on Dec. 23rd, 2017 to conduct long-term and continuous global observations in order to elucidate the global warming mechanisms related to fluctuations in radiation budget and/or carbon cycles etc.

The onboard sensor SGLI (Second Generation Global Imager) can observe 19 bands of radiations from near-ultraviolet to thermal infrared region (380 nm-12 µm), which yield various physical properties related to cloud, water, snow, ice, aerosol, sea, land, vegetation, biomass, chlorophyll a, and photosynthesis. The spatial resolution and swath of SGLI are 250m and greater than 1,000 km respectively and the whole globe can be scanned approximately in every two days.

SGLI can observe 15 Essential Climate Variables (ECV) such as cloud, aerosols, vegetation, etc. and its data are expected to contribute to improve the projection accuracy of climate change and also to predict fishing grounds, yellow sands, red tides, etc.

An experimental Japanese satellite has ended its mission after proving it could operate at super-low altitudes, testing an Earth-imaging camera and using ion propulsion to fight against aerodynamic drag at an altitude of 112 miles (181 kilometers).

The Japan Aerospace Exploration Agency's Tsubame satellite, named for the Japanese word for barn swallow, re-entered the atmosphere Oct. 2 after a nearly three-year mission.

Tsubame, also known as the Super Low Altitude Test Satellite, demonstrated controlled flight in an unusually low orbit, skimming through the rarefied layers of the upper atmosphere where aerodynamic drag typically causes spacecraft to quickly drop out of orbit and burn up.

JAXA's Tsubame satellite carried an ion thruster, powered by electricity and fueled by xenon gas, to counteract the effect of atmospheric drag. The spacecraft also had an on-board camera to demonstrate the capability to collect high-resolution images of cities and landforms from an altitude as low as 112 miles.

With some exceptions, most Earth-imaging satellites typically fly at altitudes between 300 and 400 miles (500-650 kilometers).

Built by Mitsubishi Electric Corp., Tsubame launched aboard an H-2A rocket in December 2017 into an elliptical, or egg-shaped, orbit with a low point around 280 miles (450 kilometers) above Earth, then maneuvered into a 243-mile-high (392-kilometer) orbit in early 2018. Ground controllers allowed aerodynamic drag to gradually lower Tsubame's orbit to an altitude of 168 miles (271 kilometers).

At that altitude, Tsubame activated its ion engine to maintain its orbit for one month. Then Tsubame switched off the xenon thruster to allow the spacecraft to drop into lower orbits at 155 miles (250 kilometers), 149 miles (240 kilometers) and 142 miles (230 kilometers), stopping to maintain each altitude for around one week using the ion engine.

Tsubame used its low-thrust ion engine to hold altitude at around 134 miles (217 kilometers) for approximately one month, then lowered its orbit to 112 miles (181 kilometers) in September for one week, again maintaining altitude using its xenon thruster.

The satellite then stabilized its orbit at 104 miles (167 kilometers) for several days. At that altitude, Tsubame had to use its liquid-fueled higher-thrust rocket jets to in conjunction with the ion engine to counteract drag.

The satellite re-entered the atmosphere earlier this month after completing its experiments, JAXA said.

Future satellites operating in such low orbits could offer several advantages to developers, including reduced costs for their imaging instruments and launch services.

A smaller camera on a low-altitude satellite could capture the same quality of images as a more powerful camera on a spacecraft in a higher orbit. An Earth-imaging satellite launched into a lower orbit might also need a less expensive rocket, according to JAXA.

A European Space Agency satellite named GOCE flew in a super-low orbit with the aid of an ion engine to measure Earth's gravitational field and ocean circulation before running out of fuel in 2013 after a four-year mission.

But Tsubame is the first satellite to test an Earth observation instrument while using electric propulsion to maintain such a low orbit.

Tsubame also carried an experimental coating on the craft's thermal insulation to prevent damage from atomic oxygen, a gas present at the orbiting testbed's low operating altitude. Atomic oxygen is known to damage the multi-layer insulation typically used on satellites, according to JAXA.

JAXA said knowledge gained from the Tsubame mission will be useful in future space applications in science and technology.

ТОКИО, 25 дек - РИА Новости. Японское аэрокосмическое агентство (JAXA) сообщило, что испытательный спутник "Цубамэ" совершил полет и наблюдения за Землей на сверхнизкой орбите в 167,4 километра и был занесен в Книгу рекордов Гиннеса.

Как отметило агентство, на сегодняшний день нет ни одного спутника, которому бы удалось облететь планету на меньшей высоте. Чем ниже полет, тем детальнее космическому аппарату удается произвести наблюдения и съемку, однако на высоте ниже 300 километров возрастает сопротивление воздуха и ускоряется износ оборудования.

Спутник "Цубамэ", что в переводе означает "ласточка", был запущен в 2017 году. В апреле этого года он достиг орбиты в 271 километр, а затем снизился до 167,4 километра и сумел удержаться на этой высоте в течение семи дней, после чего срок его эксплуатации был завершен.
