“…After several failures, the first successful meteorological observations from the Martian surface were made in 1976 by the two Viking landers (Chamberlain et al 1976;Hess et al 1977;Tillman et al 1994). The main goals of these meteorological observations were to study meso-scale and planetary-scale systems and processes, to investigate boundary layer phenomena and to obtain a better understanding of the Earth's atmosphere through comparison with that of Mars.…”

The Modern Near-Surface Martian Climate: A Review of In-situ Meteorological Data from Viking to Curiosity

We analyze the complete set of in-situ meteorological data obtained from the Viking landers in the 1970s to today's Curiosity rover to review our understanding of the modern near-surface climate of Mars, with focus on the dust, CO 2 and H 2 O cycles and their impact on the radiative and thermodynamic conditions near the surface. In particular, we provide values of the highest confidence possible for atmospheric opacity, atmospheric pressure, near-surface air temperature, ground temperature, near-surface wind speed and direction, and near-surface air relative humidity and water vapor content. Then, we study the diurnal, seasonal and interannual variability of these quantities over a span of more thanThe original version of this article was revised because due to an unfortunate turn of events a wrong value was published in Table 1. The resolution of the PHX pressure sensor was published as "0.1 mbar" whereas this value has now been corrected to "0.1 Pa" which is the correct value and should be regarded as the final version by the reader.

“…There was one fortunate aspect in the new and old seasons-the expected surface pressure was almost identical. Evaluation of VL lander surface pressure data (Chamberlain et al 1976) and MSL REMS surface pressure data (Gomez-Elvira et al 2012) for the two seasons at the landing local time indicated that the pressure at L s = 295…”

Selection of the InSight Landing Site

The selection of the Discovery Program InSight landing site took over four years from initial identification of possible areas that met engineering constraints, to downselection via targeted data from orbiters (especially Mars Reconnaissance SPAC 11214 layout: Small Condensed v.2.1 file: spac321.tex (ELE) class: spr-small-v1.2 v.2016/06/09 Prn:2016/12/02; 14:37 p. 1/91» « d o c to p i c : R e v i e w P a p e rn u m b e r i n g s t y l e : C o n t e n t O n l yr e f e r e n c e s t y l e : a p s » latitude (initially 15°S-5°N and later 3°N-5°N for solar power and thermal management of the spacecraft), ellipse size (130 km by 27 km from ballistic entry and descent), and a load bearing surface without thick deposits of dust, severely limited acceptable areas to western Elysium Planitia. Within this area, 16 prospective ellipses were identified, which lie ∼600 km north of the Mars Science Laboratory (MSL) rover. Mapping of terrains in rapidly acquired CTX images identified especially benign smooth terrain and led to the downselection to four northern ellipses. Acquisition of nearly continuous HiRISE, additional Thermal Emission Imaging System (THEMIS), and High Resolution Stereo Camera (HRSC) images, along with radar data confirmed that ellipse E9 met all landing site constraints: with slopes <15°at 84 m and 2 m length scales for radar tracking and touchdown stability, low rock abundance (<10 %) to avoid impact and spacecraft tip over, instrument deployment constraints, which included identical slope and rock abundance constraints, a radar reflective and load bearing surface, and a fragmented regolith ∼5 m thick for full penetration of the heat flow probe. Unlike other Mars landers, science objectives did not directly influence landing site selection. AUTHOR'S PROOF

“…Since exact power levels are difficult to predict, the power required from the MTV is set at twice that ex-pected. Survival power levels are estimated as 250 watts per satellite 22 which makes a total of 500 watts of electrical power required by each satellite while attached to the MTV. Minimum telemetry will be available.…”

“…The values shown in Table 13 are representative of the calculated AVs and mission durations associated with the conjunction class missions. 22 These class of scenarios represent Hohmann transfer trajectories and therefore have the smallest overall AV magnitudes. However, due to the lower AV totals, the mission durations are longer than any other scenario.…”

Using a five phase plan involving an early moon base and thred scientific missions to Mars followed by cargo missions and eventually manned trips to the planet, the authors analyzed, designed, and documented their approach. The report focuses on the second phase of the project --scientific expansion of our knowledge of Mars and proof of a reliable transportation system. Among the subjectsi discussed in the report are management, mission profile and environment, and mission systems. The latteri subject contains a variety of systems proposed by various authorities in the space industry and selected to fulfill the unique requirements of the project. Because this phase is an integral part of the project, emphasis was on2 reusability and versatility.14. ... Our goal is to build on America's pioneer spirit and develop our next frontier.. .space. Nowhere do we so effectively demonstrate our technological leadership and ability to make life better on Earth.. .Our progress in space-taking giant steps for all mankind-is a tribute to American teamwork and excellence.. .We can follow our dreams to distant stars, living and working in space for peaceful, economic, and scientific gain. List of Tables President Ronald Reagan State of the Union Address 25 January 1984The first generation of space-probes has revealed so much strangeness and grandeur on our neighboring worlds that, as soon as the technical means are available, men will certainly visit them. And having done this, they will find reasons for living there-as on this earth they have established themselves in such improbable spots as the South Pole and the bottom of the ocean. Space itself, to the considerable surprise of most people, has turned out to be a benign environment; it is only the planets that are hostile. Even this was anticipated almost a century ago by Tsiolkovsky; he regarded the weightless realm of space as man's ultimate home.. .The escape from gravity which we have all known in our dreams may remind us of life's origins in the ocean; but it may also anticipate a far longer future in space.
