Omówione tu są misje marsjańskie od zarania astronautyki do 2003 roku. Zarówno misje udane, nieudane jak i propozycje oraz projekty takich misji. Można tu sporo się dowiedzieć o udanych misjach marsjańskich zwłaszcza amerykańskich, etapach wybierania lądowisk, trasach potencjalnych misji roverów itp.

NASA, international InSight mission nail PERFECT landing on Mars
written by Chris Gebhardt November 25, 2018

The Martian Challenge:

From the 1600s to the 1960s, all the information humanity had on Mars came solely from ground-based telescopes – a feat in itself.  But with the dawn of rocketry came a new means of exploring the tantalizing Red Planet that had for so long captured our imaginations and fancy.

Since the beginning of the space age, the exploration of Mars figured prominently in the space programs of the United States and Russia (formerly the Union of Soviet Socialist Republics) – expanding in the 1990s to include Japan, in the 2000s to include the European Space Agency (ESA), and in the 2010s to include India and China.

On 10 October 1960, Earth’s first space probe to Mars was launched by the USSR.  Named Mars 1M No.1, the mission ended shortly after liftoff in a launch failure. And with that failure, the reality of up-close exploration of Mars was realized.

Mars was never going to be easy, and it was going to challenge us in ways we didn’t expect.  Since 10 October 1960, 56 missions (some bundled together resulting in two missions launching together) to Mars – be they flybys, orbiters, landers, rovers, and/or sample returns – have been launched by NASA, Russia/USSR, Japan, ESA, China, and India.

Of those 56 missions, 56 to date, including InSight and the Mars Cube One flights, have attempted to successfully arrive at Mars and either flyby, insert themselves into orbit, or land on the surface.

Of those 56 attempts, the results stand as thus:

Successes               Partial Successes                                      Failures
       27                                         8                                             21

This gives an overall global average for Mars mission success of 48% if only complete successes are taken.  To say the least, the figures tell a clear story of how difficult in-situ exploration of Mars is, and the figures for landers and rovers are even more daunting. 

In all, 19 lander/rover missions have been attempted to Mars, including InSight.  Of those, 8 have ended in failures, 3 in partial successes, and only 8 in successes – a 42% success rate.

Despite those daunting global odds, NASA has a nearly unbelievable success rate with Mars lander/rover missions.  Including InSight, NASA has sent 11 landers/rovers to Mars with an 82% success rate. Only the Mars Polar Lander and Deep Space 2 hard landers (two components of the same mission) crash-landed on the Red Planet in 1999 due to improper hardware testing.

Despite that failure (and a few others), NASA’s overall Martian success rate is an impressive 80%, with accomplishments including:

  -First completely successful mission to Mars with Mariner 4
  -First successful Martian orbiter with Mariner 9
  -First completely successful Martian landing with Viking 1
  -First successful Martian rover with Sojourner
  -Longest-surviving Human technology on another world with the Mars Exploration Rover Opportunity.
 
InSight was the 19th lander to attempt a touchdown on the Martian surface.

Powiem szczerze, nie widziałem w swoim życiu bardziej szczegółowego opracowania i reasumy każdej z marsjańskich misji. Dziękuję za ten link - genialna sprawa.
Teraz też dopiero skojarzyłem autora, przecież to słynny kartograf, tak mocno udzielający się również na unmannedspaceflight, no i odkrywca ostatecznego położenia pojazdu Łunochod-2.

Rosyjski plan podboju wszechświata: nowa stacja orbitalna do 2030, baza księżycowa w okolicach 2035, załogowy przyczółek marsjański w 2040.....stacja naukowa na Tytanie - 2055....Jakieś pytania jeszcze?

A co powiesz Station na tą książkę?

Niestety tej w necie nie przeczytasz a na polskie pieniądze to finansowo ciężki zakup  :(

50 lat temu NASA po raz drugi wykorzystała z sukcesem okno startowe do udanych misji Marinera-6 i Marinera-7

50 Years Ago: Mariner 6 and 7 off to Mars
Feb. 25, 2019


Left and middle: Launch of Mariner 6 and 7. Right: Mariner 6 and 7 spacecraft.

While much of NASA’s focus in 1969 centered on accomplishing President John F. Kennedy’s goal of landing a man on the Moon before the end of the decade, the Agency was also exploring further out in the solar system using robotic spacecraft. Managed by the Jet Propulsion Laboratory in Pasadena, California, Mariner 6 and 7 were NASA’s next steps in the exploration of Mars. Previously, only one spacecraft, Mariner 4, had made a successful reconnaissance of the Red Planet. It beamed back to Earth 22 black and white images of Mars during its fly-by in July 1965, showing a Moon-like heavily cratered surface. Shortly after that pioneering encounter, NASA authorized the Mariner Mars 1969 project, consisting of two identical spacecraft to make closer fly-bys of the Red Planet and take more detailed photographs and other measurements. Each 908-pound spacecraft carried eight experiments to study the atmosphere and surface of Mars during their fly-bys of the planet. The experiments were:  an infrared spectrometer; an infrared radiometer to measure the surface temperature of Mars; an ultraviolet spectrometer; an S-band occultation experiment; a thermal control flux monitor; a television camera system with wide- and narrow-angle telescopes; a celestial mechanics experiment; and a general relativity experiment.

During a countdown test on Feb. 14, 1969, a malfunction in Mariner 6’s unfueled Atlas rocket caused helium pressure gas, used to keep the booster rigid, to escape. The rocket began to crumple, but two technicians, Bill McClure and Jack Beverlin quickly activated a manual override and repressurized the rocket. Although the booster was damaged, the technicians’ action saved the spacecraft and its Centaur upper stage. For their quick thinking in a dangerous situation, they each received an Exceptional Bravery Medal and in 2014 an escarpment on Mars was posthumously named the McClure-Beverlin Ridge in their honor.

Engineers quickly placed Mariner 6 and its Centaur on top of the rocket planned for Mariner 7, and launched it on schedule and without incident on Feb. 25, 1969. Mariner 7, on top of a new Atlas-Centaur, followed on Mar. 27. Their respective Centaur upper stages sent them on their way to Mars. Course corrections on Mar. 1 for Mariner 6 and Apr. 8 for Mariner 7 refined their trajectories. Because of their different paths, the two spacecraft arrived at Mars just five days apart despite the month separating their launches. After a flight of 156 days from Earth, Mariner 6 flew within 2,132 miles of Mars on July 31, roughly twice as close as Mariner 4’s flyby in 1965. During the encounter, the spacecraft returned 75 photographs and science data. Contact was temporarily lost with Mariner 7 just five days before its planned encounter, but by Aug. 2 the spacecraft was restored to full capability as it began its encounter with Mars. Three days later, it passed within 2,130 miles of Mars’ southern hemisphere, returning 126 photographs and science data.
