In October , astronomers reported a significant unexpected increase in density in the space beyond the Solar System as detected by the Voyager 1 and Voyager 2 space probes.
According to the researchers, this implies that "the density gradient is a large-scale feature of the VLISM very local interstellar medium in the general direction of the heliospheric nose ".
Voyager 1 is expected to reach the theorized Oort cloud in about years   and take about 30, years to pass through it. Provided Voyager 1 does not collide with anything and is not retrieved, the New Horizons space probe will never pass it, despite being launched from Earth at a higher speed than either Voyager spacecraft.
The Voyager spacecraft benefited from multiple planetary flybys to increase their heliocentric velocities, whereas New Horizons received only a single such boost, from its Jupiter flyby.
In December it was announced that NASA had successfully fired up all four of Voyager 1 ' s trajectory correction maneuver TCM thrusters for the first time since The TCM thrusters will be used in the place of a degraded set of jets which were used to help keep the probe's antenna pointed towards the Earth.
Use of the TCM thrusters will allow Voyager 1 to continue to transmit data to NASA for two to three more years. Due to the diminishing electrical power available, the Voyager team has had to prioritize which instruments to keep on and which to turn off.
Heaters and other spacecraft systems have been turned off one by one as part of power management. The fields and particles instruments that are the most likely to send back key data about the heliosphere and interstellar space have been prioritized to keep operating.
Engineers expect the spacecraft to continue operating at least one science instrument until around Simulated view of the Voyager probes relative to the Solar System and heliopause on August 2, Each Voyager space probe carries a gold-plated audio-visual disc , should the spacecraft ever be found by intelligent life forms from other planetary systems.

In July , a new plan to better manage the two Voyager space probes was implemented. The two Voyager space probes were originally conceived as part of the Mariner program , and they were thus initially named Mariner 11 and Mariner They were then moved into a separate program named "Mariner Jupiter-Saturn", later renamed the Voyager Program because it was thought that the design of the two space probes had progressed sufficiently beyond that of the Mariner family to merit a separate name.
The Voyager Program was similar to the Planetary Grand Tour planned during the late s and early 70s. The Grand Tour would take advantage of an alignment of the outer planets discovered by Gary Flandro , an aerospace engineer at the Jet Propulsion Laboratory.
This alignment, which occurs once every years,  would occur in the late s and make it possible to use gravitational assists to explore Jupiter, Saturn, Uranus, Neptune, and Pluto.
The Planetary Grand Tour was to send several pairs of probes to fly by all the outer planets including Pluto, then still considered a planet along various trajectories, including Jupiter-Saturn-Pluto and Jupiter-Uranus-Neptune.
Limited funding ended the Grand Tour program, but elements were incorporated into the Voyager Program, which fulfilled many of the flyby objectives of the Grand Tour except a visit to Pluto.
Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune. Voyager 1 was launched after Voyager 2 , but along a shorter and faster trajectory that was designed to provide an optimal flyby of Saturn's moon Titan ,  which was known to be quite large and to possess a dense atmosphere.
This encounter sent Voyager 1 out of the plane of the ecliptic, ending its planetary science mission. During the s, Voyager 1 overtook the slower deep-space probes Pioneer 10 and Pioneer 11 to become the most distant human-made object from Earth, a record that it will keep for the foreseeable future.
The New Horizons probe, which had a higher launch velocity than Voyager 1 , is travelling more slowly due to the extra speed Voyager 1 gained from its flybys of Jupiter and Saturn.
Voyager 1 and Pioneer 10 are the most widely separated human-made objects anywhere since they are travelling in roughly opposite directions from the Solar System.
In December , Voyager 1 crossed the termination shock , where the solar wind is slowed to subsonic speed, and entered the heliosheath , where the solar wind is compressed and made turbulent due to interactions with the interstellar medium.
On 10 December , Voyager 2 also reached the termination shock, about 1 billion miles closer to the Sun than from where Voyager 1 first crossed it, indicating that the Solar System is asymmetrical.
In Voyager 1 reported that the outward velocity of the solar wind had dropped to zero, and scientists predicted it was nearing interstellar space.
Scientists at NASA reported that Voyager 1 was very close to entering interstellar space, indicated by a sharp rise in high-energy particles from outside the Solar System.
In December , NASA announced that Voyager 2 had crossed the heliopause on 5 November , making it the second spacecraft to enter interstellar space.
As of [update] Voyager 1 and Voyager 2 continue to monitor conditions in the outer expanses of the Solar System. Sometime around , there will no longer be sufficient power to operate any science instruments.
In July , a new plan to better manage the two Voyager space probes was proposed. The Voyager spacecraft each weigh kilograms 1, pounds.
Of this total weight, each spacecraft carries kilograms pounds of scientific instruments. The diagram shows the high-gain antenna HGA with a 3. There is also a spherical tank that contains the hydrazine monopropellant fuel.
The Voyager Golden Record is attached to one of the bus sides. The angled square panel to the right is the optical calibration target and excess heat radiator.
The three radioisotope thermoelectric generators RTGs are mounted end-to-end on the lower boom. The scan platform comprises: the Infrared Interferometer Spectrometer IRIS largest camera at top right ; the Ultraviolet Spectrometer UVS just above the IRIS; the two Imaging Science Subsystem ISS vidicon cameras to the left of the UVS; and the Photopolarimeter System PPS under the ISS.
Only five investigation teams are still supported, though data is collected for two additional instruments.
The FDS configures each instrument and controls instrument operations. It also collects engineering and science data and formats the data for transmission.
The DTR is used to record high-rate Plasma Wave Subsystem PWS data. The data are played back every six months. The Imaging Science Subsystem made up of a wide-angle and a narrow-angle camera is a modified version of the slow scan vidicon camera designs that were used in the earlier Mariner flights.
The Imaging Science Subsystem consists of two television-type cameras, each with eight filters in a commandable filter wheel mounted in front of the vidicons.
There are three different computer types on the Voyager spacecraft, two of each kind, sometimes used for redundancy.
They are proprietary, custom-built computers built from CMOS and TTL medium scale integrated circuits and discrete components.
Total number of words among the six computers is about 32K. Voyager 1 and Voyager 2 have identical computer systems. The Computer Command System CCS , the central controller of the spacecraft, is two bit word, interrupt type processors with words each of non-volatile plated wire memory.
During most of the Voyager mission the two CCS computers on each spacecraft were used non-redundantly to increase the command and processing capability of the spacecraft.
The CCS is nearly identical to the system flown on the Viking spacecraft. The Flight Data System FDS is two bit word machines with modular memories and words each.
The Attitude and Articulation Control System AACS is two bit word machines with words each. Unlike the other on-board instruments, the operation of the cameras for visible light is not autonomous, but rather it is controlled by an imaging parameter table contained in one of the on-board digital computers , the Flight Data Subsystem FDS.
More recent space probes, since about , usually have completely autonomous cameras. The computer command subsystem CCS controls the cameras.
The CCS contains fixed computer programs such as command decoding, fault detection, and correction routines, antenna pointing routines, and spacecraft sequencing routines.
This computer is an improved version of the one that was used in the Viking orbiter. There is only a minor software modification for one of them that has a scientific subsystem that the other lacks.
The Attitude and Articulation Control Subsystem AACS controls the spacecraft orientation its attitude. It keeps the high-gain antenna pointing towards the Earth, controls attitude changes, and points the scan platform.
The custom-built AACS systems on both craft are identical. It has been erroneously reported  on the Internet that the Voyager space probes were controlled by a version of the RCA RCA CDP "COSMAC" microprocessor , but such claims are not supported by the primary design documents.
The CDP microprocessor was used later in the Galileo space probe , which was designed and built years later. The digital control electronics of the Voyagers were not based on a microprocessor integrated circuit chip.
The uplink communications are executed via S-band microwave communications. The downlink communications are carried out by an X-band microwave transmitter on board the spacecraft, with an S-band transmitter as a back-up.
All long-range communications to and from the two Voyagers have been carried out using their 3. The high-gain antenna has a beamwidth of 0.
Because of the inverse-square law in radio communications , the digital data rates used in the downlinks from the Voyagers have been continually decreasing the farther that they get from the Earth.
For example, the data rate used from Jupiter was about , bits per second. That was halved at the distance of Saturn, and it has gone down continually since then.
Whilst the craft were between Saturn and Uranus the onboard software was upgraded to do a degree of image compression and to use a more efficient Reed-Solomon error-correcting encoding.
Then between and , new techniques were brought into play to combine the signals from multiple antennas on the ground into one, more powerful signal, in a kind of an antenna array.
Also, in Australia, the Parkes Radio Telescope was brought into the array in time for the fly-by of Neptune in In the United States, the Very Large Array in New Mexico was brought into temporary use along with the antennas of the Deep Space Network at Goldstone.
Electrical power is supplied by three MHW-RTG radioisotope thermoelectric generators RTGs. They are powered by plutonium distinct from the Pu isotope used in nuclear weapons and provided approximately W at 30 volts DC when the spacecraft was launched.
Plutonium decays with a half-life of The RTG thermocouples , which convert thermal power into electricity, also degrade over time reducing available electric power below this calculated level.
By 7 October the power generated by Voyager 1 and Voyager 2 had dropped to The level of power output was better than pre-launch predictions based on a conservative thermocouple degradation model.
As the electrical power decreases, spacecraft loads must be turned off, eliminating some capabilities. There may be insufficient power for communications by The Voyager primary mission was completed in , with the close flyby of Neptune by Voyager 2.
The Voyager Interstellar Mission VIM is a mission extension, which began when the two spacecraft had already been in flight for over 12 years.
The panel found that the VIM "is a mission that is absolutely imperative to continue" and that VIM "funding near the optimal level and increased DSN Deep Space Network support is warranted.
The main objective of the VIM is to extend the exploration of the Solar System beyond the outer planets to the outer limit and if possible even beyond.
The Voyagers continue to search for the heliopause boundary which is the outer limit of the Sun's magnetic field.
Passing through the heliopause boundary will allow the spacecraft to make measurements of the interstellar fields, particles and waves unaffected by the solar wind.
The entire Voyager 2 scan platform, including all of the platform instruments, was switched off in All platform instruments on Voyager 1 , except for the ultraviolet spectrometer UVS  have also been switched off.
The Voyager 1 scan platform was scheduled to go off-line in late but has been left on to investigate UV emission from the upwind direction.
UVS data are still captured but scans are no longer possible. Gyro operations ended in for Voyager 2 and in for Voyager 1.
Gyro operations are used to rotate the probe degrees six times per year to measure the magnetic field of the spacecraft, which is then subtracted from the magnetometer science data.
The two spacecraft continue to operate, with some loss in subsystem redundancy but retain the capability to return scientific data from a full complement of Voyager Interstellar Mission VIM science instruments.
Both spacecraft also have adequate electrical power and attitude control propellant to continue operating until around , after which there may not be electrical power to support science instrument operation; science data return and spacecraft operations will cease.
