Short Course: Historical Highlights of Planetary Probe Missions

Short Course for the International Planetary Probe Workshop 2024

June 8th and 9th

Short Course Description

It is almost 60 years since the first successful landings on other planetary bodies (Luna 9) and almost 50 since images came back from other worlds (Venera 9, Viking). The short course has a compilations of a series of presentations featuring scholars of these endeavors, and including some of the protagonists themselves to share their direct experience of international planetary mission developments, to highlight the challenges and triumphs, and to offer lessons learned for future efforts. In addition to the successful projects, the course will also touch on planetary missions that were lost, and review the counterfactual history of how planetary exploration might have been very different had they succeeded.

In the spirit of IPPW itself, the topics cover scientific, engineering and programmatic aspects.

 

Topics covered will include:

  • Key planetary entry probe demonstrators (e.g. PAET)

  • First close-up investigation of Mars and preparation for Viking

  • Into the hellish depths of Venus with the Venera probes

  • Galileo and Pioneer Venus probes

  • Radio science highlights

  • Parachute development

  • Thermal Protection Systems

  • Huygens

  • Beagle 2

  • Small bodies landers

  • Information sources on historical probe missions

  • Trivia quiz!

Short Course Abstracts

Arnold - Planetary Atmospheric Entry Test  (PAET)

This presentation summarizes the instrumentation and analysis of flight data from the PAET which proved that results from an entry probe mission can be used to determine the structure and composition of an unknown planetary atmosphere. Focus is on the atmospheric structure and radiometry experiments.

Ball - Beyond the Internet - Information Sources on Planetary Missions

From learning about the field as a student to researching topics in a professional capacity, the targeting, discovery and harvesting of information on planetary missions has evolved greatly since the days of standing over the photocopier with bound volumes of journals. Andrew presents some personal favorites and tips from the libraries and obscure corners of the internet.

Gage - Heritage in Planetary Missions,  A Double-edged Sword

Previous missions can provide invaluable guidance for design and implementation of new missions. Failures and near misses can be particularly useful for defining capability boundaries and problematic operating environments. Nevertheless, caution must be exercised to avoid misapplication of prior experience to new circumstances. Examples that demonstrate benefits and pitfalls of heritage will be provided.

Cutts - First Closeups of Mars and the lead-up to Viking

In 1976, a Viking Orbiter spacecraft delivered a lander spacecraft into Venus orbit with a plan to land on July 4th celebrating the 200th anniversary of the United States. The orbiter was equipped with a camera barely able to resolve an object the size of a football stadium but the lander was vulnerable to landing on a rock no bigger than a football.  This presentation describes how this all worked out.

 

Lorenz/Ball - First into the hellish depths: the Venera/VEGA Landers

The Soviet Venera probe program included an evolving series of probes/landers that from the 1960s to the 1980s penetrated progressively deeper into the Venus atmosphere, then returned the first pictures from the surface of another planet (almost 50 years ago!), and even drilled into and analyzed surface rocks. A successor pair of missions, VeGa, featured balloons as well as landers. We review these striking achievements.

 

Bienstock -  Pioneer Venus and Galileo Probes :  Launching NASA’s Planetary Probe Missions in the 20th Century

A time travel back to the exciting era of designing vehicles to probe the mysteries of Venus and Jupiter.

 

Asmar - Radio Highlights

An overview of past, current, and future applications of radio signals for communications and scientific applications on planetary probes.

O'Farrell/Siegler - Aerodynamic Decelerator Systems: Advances in the Last Two Decades

A review of parachute and related technology development and flight highlights.

 

Venkatapathy/Gasch - History of Ablative TPS used in NASA Missions

Planetary exploration began with the invention of the blunt body concept along with the use of ablative TPS. These led to the success of Apollo mission and scientific community taking advantage of the success soon followed exploration of inner and outer planets in the (1970 – 1980).  Sample return missions and further exploration of Mars with much larger landers in the (2000 – 2020) all needed ablative TPS.  This talk will highlight the TPS used in NASA missions since 1950’s. 

Pichon - Historical highlights of European Thermal Protection System Development

Presentation of the major achievements obtained on thermal protection systems designed and produced in Europe for various applications and re-entry vehicles

Yamada - Japanese Sample Return Missions from Asteroids: "Hayabusa and Hayabusa2"

Presentation of the results and achievements in "Hayabusa" and "Hayabusa2" sample return missions, especially, development of sample return capsule and recovery operations.

Chester - Beagle2 20 Years Later

What It Was, Was Supposed To Do, and What It Did.

 

Witte - Small Body Landings

The journeys of the micro-lander »Philae« (onboard ESA Rosetta) to comet 67P/Churyumov-Gerasimenko and »MASCOT« (onboard JAXA Hayabusa 2) to asteroid 1999JU3/Ryugu.

 

Lorenz - Huygens

The Huygens probe to Titan was the European Space Agency’s first probe mission, confronting the agency, industry, and university partners with unfamiliar challenges.  The NASA/ESA/ASI Cassini-Huygens mission was an outstanding example of international collaboration. The talk reviews some highlights of Huygens technical development, its operation and its findings, which set the stage for future exploration.

 

Lorenz/Chester/Ball - Beyond the Agencies:  Commercial and other paradigms

Although national and international space agencies have led the formidable enterprise of planetary exploration, commercial and other entities have occasionally entered the arena and may do so much more in future.  Relevant previous projects include the (radio) Amateur Satellite organization AMSAT, the grass-roots effort to develop the mission that became Lunar Prospector, and the unconventional funding model of Beagle 2: recent projects have included several commercial lunar landing efforts, and a Rocket Labs Venus probe mission. Interestingly, these paradigms may resemble the sponsorship of large astronomical observatories in the 19th century by private individuals.
