Russia’s Space Agency, Roscosmos, has set November 9 as the launch date for the Phobos-Grunt mission to Mars and its tiny moon Phobos. Roscosmos has officially announced that the audacious mission to retrieve the first ever soil samples from the surface of Phobos will blastoff from the Baikonur Cosmodrome in Kazakhstan atop a Zenit-2SB rocket at 00:16 a.m. Moscow time.

Roscosmos said that engineers have finished loading all the propellants into the Phobos-Grunt main propulsion module (cruise stage), Phobos lander and Earth return module at Facility 31 at Baikonur.

Phobos-Grunt is Russia’s first mission to Mars in almost two decades and a prelude to an ambitious program of even more interplanetary Russian science flights.

Technicians also fueled the companion Yinghou-1 mini-satellite, provided by China, that will ride along inside a truss segment between the MDU propulsion module and the Phobos-Grunt lander.

The 12,000 kg Phobos-Grunt interplanetary spacecraft is being moved to an integration and test area at Facility 31 for integration with the departure segments of the Zenit rocket.

The next step is to enclose Phobos-Grunt inside the protective payload fairing and transport it to Facility 42 for mating atop the upper stage of the stacked Zenit-2SB booster rocket.

After about an 11 month journey, the spaceship will enter Mars orbit and spend several months searching for a suitable landing site on Phobos. The goal of the bold mission is to retrieve up to 200 grams of soil and rock from Phobos and return them to Earth in August 2014. The samples will help unlock the mysteries of the origin and evolution of Phobos, Mars and the Solar System.

Scientists hope that bits of Martian soil will be mixed in with Phobos soil.

Phobos-Grunt is equipped with a powerful 50 kg payload of some 20 international science instruments.

The 110 kg Yinghou-1, which translates as Firefly-1, is China’s first spaceship to voyage to Mars. It will be jettisoned by Phobos-Grunt into a separate orbit about Mars. The probe will photograph the Red planet with two cameras and study it with a magnetometer to explore Mars’ magnetic field and science instruments to explore its upper atmosphere.

Earth’s other mission to Mars in 2011, NASA’s Curiosity rover, is set to blast off for Mars on Nov. 25

Barely in the nick of time, Russia’s groundbreaking Phobos-Grunt interplanetary spacecraft to Mars finally arrived on Monday (Oct. 17) at the Baikonur Cosmodrome launch site in Kazakhstan – and today (Oct. 18) an eye-popping collection of great images (see below) was at last published by Roskosmos, the Russian Federal Space Agency.

This first-of-its-kind spaceship is due to blast off quite soon – sometime in the first half of November – although Roskosmos has yet to announce an official launch date and time is running out. The deadline to Mars is Nov. 25.

The explicit close-up photos show both the Phobos-Grunt orbiter/lander vehicle and her companion Yinghou-1 Mars orbiter, built by China, being uncrated from a huge shipping container, uprighted and then showcased from many revealing angles from top to bottom, tilted from side to side and looking inside her hardware stack.

The photos illustrate the solar panels, landing legs, J-shaped soil sampling tube, Earth return vehicle and descent capsule, star trackers, communications antennae, maneuvering thrusters and more.

The Yinghou-1 mini-satellite is clearly visible tucked inside a truss situated between the Phobos-Grunt landing ship and the MDU propulsion stage.

Phobos-Grunt was just air shipped from Moscow to Baikonur inside an Antonov An-124-100 “Ruslan” cargo plane operated by “Polyot” airline.

The cargo canister was offloaded and transported by truck to Facility 31. The spacecraft was then placed on a test stand to begin an intense period of final prelaunch payload processing activites to ready the probe for launch.

The Zenit-2SB booster rocket also recently arrived at Baikonur for ongoing prelaunch processing at nearby Building 42.

Earth is actually lofting two exciting science missions to Mars this November. NASA’s Curiosity Mars Science Laboratory rover is due to blastoff on Nov. 25 and her launch window extends until Dec. 18. Both spaceships missed their initially targeted launch windows in 2009 due to the need to fix unresolved technical issues.

Phobos-Grunt is a daring sample return mission whose goal is to retrieve up to 200 grams of soil and rock from the tiny Martian moon Phobos, that will help elucidate the origin and evolution of Phobos, Mars and the Solar System.

Russia is marking the upcoming blastoff of their dauntingly complex Phobos-Grunt sample return mission to the Martian moon Phobos with the release of a quite cool looking mission poster – see above. Phobos-Grunt translates as Phobos-Soil and is due to liftoff on or about November 7, 2011 from the Baikonur Cosmodrome atop a Zenit rocket.

The holy grail of Mars exploration has long been a sample return mission. But with severe cutbacks to NASA’s budget that goal is realistically more than a decade away. That’s why Phobos- Grunt is so exciting from a scientific standpoint.

If successful, this audacious probe will retrieve about 200 grams of soil from the diminutive moon Phobos and accomplish the round trip in three years time by August 2014. Scientists speculate that martian dust may coat portions of Phobos and could possibly be mixed in with any returned samples.

Included here are more photos and graphics of the Phobos-Grunt spacecraft which is equipped with two robotic arms and a sampling device to transfer regolith and rocks to the Earth return vehicle and an on board array of some 15 science instruments, including lasers, spectrometers, cameras and a microscope.

In just over 3 weeks’ time, Russia plans to launch a bold mission to Mars whose objective, if successful , is to land on the Martian Moon Phobos and return a cargo of precious soil samples back to Earth about three years later.

The purpose is to determine the origin and evolution of Phobos and how that relates to Mars and the evolution of the solar system.

Liftoff of the Phobos-Grunt space probe will end a nearly two decade long hiatus in Russia’s exploration of the Red Planet following the failed Mars 96 mission and is currently scheduled to head to space just weeks prior to this year’s other Mars mission – namely NASA’s next Mars rover, the Curiosity Mars Science Laboratory (MSL).

Blastoff of Phobos-Grunt may come as early as around Nov. 5 to Nov. 8 atop a Russian Zenit 3-F rocket from the Baikonur Cosmodrome in Kazakhstan. The launch window extends until about Nov. 25. Elements of the spacecraft are undergoing final prelaunch testing at Baikonur.

Baikonur is the same location from which Russian manned Soyuz rockets lift off for the International Space Station. Just like NASA’s Curiosity Mars rover, the mission was originally intended for a 2009 launch but was prudently delayed to fix a number of technical problems.

“November will see the launch of the Phobos-Grunt interplanetary automatic research station aimed at delivering samples of the Martian natural satellite’s soil to Earth’” said Vladimir Popovkin, head of the Russian Federal Space Agency, speaking recently at a session of the State Duma according to the Voice of Russia, a Russian government news agency.

The spacecraft will reach the vicinity of Mars after an 11 month interplanetary cruise around October 2012. Following several months of orbital science investigations of Mars and its two moons and searching for a safe landing site, Phobos-Grunt will attempt history’s first ever touchdown on Phobos. It will conduct a comprehensive analysis of the surface of the tiny moon and collect up to 200 grams of soil and rocks with a robotic arm and drill.

After about a year of surface operations, the loaded return vehicle will blast off from Phobos and arrive back at Earth around August 2014. These would be the first macroscopic samples returned from another body in the solar system since Russia’s Luna 24 in 1976.

“The way back will take between nine and 11 months, after which the return capsule will enter Earth’s atmosphere at a speed of 12 kilometers per second. The capsule has neither parachute nor radio communication and will break its speed thanks to its conical shape,” said chief spacecraft constructor Maksim Martynov according to a report from the Russia Today news agency. He added that there are two soil collection manipulators on the lander because of uncertainties in the characteristics of Phobos soil.

Phobos-Grunt was built by NPO Lavochkin and consists of a cruise stage, orbiter/lander, ascent vehicle, and Earth return vehicle.

The spacecraft weighs nearly 12,000 kg and is equipped with a sophisticated 50 kg international science payload, in particular from France and CNES, the French Space Agency.

Also tucked aboard is the Yinghou-1 microsatellite supplied by China. The 110 kg Yinghou-1 is China’s first probe to launch to Mars and will study the Red Planet’s magnetic and gravity fields and surface environment from orbit for about 1 year.

“It will be the first time such research [at Mars] will be done by two spacecraft simultaneously. The research will help understand how the erosion of Mars’ atmosphere happens,” said Professor Lev Zelyony from the Space Research Institute of the Russian Academy of Science, according to Russia Today.
