For those Mars terraforming advocates, you’ll find an interesting read from the Belfer Center for Science and International Affairs at the Harvard Kennedy School in Cambridge, Massachusetts.

A Belfer Center study group has looked at solar geoengineering – not for the Red Planet but for the Blue Marble – Earth.

Risks and uncertainties

As explained in the report, solar geoengineering has the potential to reduce climate impacts around the globe, but it also carries its own risks and uncertainties.

“The science and the governance are very challenging. The question at issue now is not about deployment,” the report notes. “It is about whether there should be a serious research effort on solar geoengineering to advance understanding on the efficacy, benefits, and risks, and to identify strategies that might make it safer.”

Moral hazard, slippery slope

Proposed solar geoengineering technologies for the Earth include:  marine cloud brightening, cirrus cloud thinning, space-based techniques, and stratospheric aerosol scattering.

There are a number of policy issues for consideration, including:

For one, the study observes, there is serious concern that talking about, researching, and/or deploying solar geoengineering will reduce incentives to cut emissions—this problem is often referred to as “moral hazard.” It is highly likely that some fossil fuel interests will seek to exploit solar geoengineering to block mitigation.

Additionally, there is also concern that research on solar geoengineering could create powerful constituencies in favor of eventual deployment. Such a potential for socio-technical lock-in is sometimes called a “slippery slope.”

The U.S. Government Accountability Office (GAO) issued today a report that flags the finding: “Due to continued production and testing challenges, NASA’s three related human spaceflight programs have encountered additional launch delays and cost growth.”

Trio of systems

NASA is developing a trio of systems to put astronauts into space: the Orion crew vehicle, Space Launch System (SLS), and Exploration Ground Systems (EGS).

“In the past we’ve reported on concerns over the way NASA is managing these large and complex efforts—such as working to overly optimistic schedules,” the new report explains. “NASA is unlikely to meet its recently revised launch date for the first test flight. In addition, its reporting of cost growth for SLS and Orion is distorted. We recommended that NASA adopt more transparent cost reporting practices.”

Reevaluate strategy

The report makes four recommendations to NASA, including that the SLS program should calculate cost growth based on costs that are currently included in the first mission and the Orion program should update its cost estimate to reflect the schedule agreed to in its baseline. In addition, the SLS and Orion programs should reevaluate their strategy for incentivizing contractors, the report adds.

“NASA’s SLS, Orion, and EGS programs are a multi-billion dollar effort to transport humans beyond low-Earth orbit, but the agency has been unable to achieve agreed-to cost and schedule performance,” notes the GAO study.

“NASA acknowledges that future delays to the June 2020 launch date are likely, but the agency’s approach in estimating cost growth for the SLS and Orion programs is misleading. And it does not provide decision makers, including the Administrator, complete cost data with which to assess whether Congress needs to be notified of a cost increase, pursuant to law,” adds the GAO assessment.

NASA’s acquisition management has been on GAO’s High Risk List since 1990.

Curiosity’s science team has planned regular weather observations, a survey of the sky at twilight, a movie looking for dust devils and a second one looking up at the clouds.

Also planned, Sumner adds, is a 360° Mastcam image to capture the regional outcrops as well as three Chemistry and Camera (ChemCam) Autonomous Exploration for Gathering Increased Science (AEGIS) analyses, where the instrument automatically selects targets within a region defined by the team.

Wally Funk’s Race for Space: The Extraordinary Story of a Female Aviation Pioneer by Sue Nelson; Chicago Review Press, 2019; hardcover: 256 pages, $26.99

This is a wonderful read, one that underscores politics and prejudice in America’s embryonic human spaceflight program. 

Wally Funk was a trailblazer, among the Mercury 13, the first group of American pilots to complete NASA’s 1961 Women in Space program.

Sue Nelson’s engaging and personal account of Funk’s lifetime pursuit of becoming an astronaut is also a story of tenacity and dogged perseverance. The book’s preface explains that in 2019, the same year as the fiftieth anniversary of the Apollo 11 Moon landing, Wally Funk will celebrate her 80th birthday.

“During that year,” Nelson writes, “she hopes to finally cash in her ticket with Virgin Galactic for one of the first commercial flights into space. Understandably, she is eager for this new era of space tourism to begin. History, for Wally, will then have come full circle.”

At age 23, Funk and her fellow women astronaut candidates participated in rigorous physical exams – as did the Mercury 7 male candidates. But the program to select female space travelers was suddenly shut down in 1961. NASA declared women could not qualify as astronauts, with the author describing the sexism facing women keen on orbital flight.

Funk went on to become one of America’s first female aviation inspectors and civilian flight instructors, with her dream of being an astronaut never fading and still intact.

The reader will find this book inspirational – a vibrant portrait of Funk’s can-do spirit and stick-to-itness. It’s a retro-fire back into space history and a tell-all tale of the flack that Funk endured.

A unique multimedia website has been launched, one that plays the entire Apollo 11 mission in real time.

Included are 2,000 photographs, 11,000 hours of Mission Control audio, 240 hours of space-to-ground audio, all onboard recorder audio, 15,000 searchable utterances, post-mission commentary, and astromaterials sample data.

The website is the most complete presentation of the mission’s historical film footage ever assembled, explains Ben Feist of NASA JSC/Jacobs-JETS.

Feist, along with archivist, Stephen Slater, produced the website that contains all of the 16mm film that was scanned for the recent film, Apollo 11.

Much of this silent film has had sound added to it for the first time, Feist adds, painstakingly lip synced with restored mission control audio that has been digitized.

The 240-hour cut

The centerpiece of the website is 11,000 hours of Mission Control audio that has been synced to mission time. For any moment in the mission, visitors can open a panel that exposes 50 channels of audio covering every controller position in Mission Control and several other communication loops.

“It’s pretty much guaranteed that visitors will see things that they’ve never seen before,” Feist explains. “All footage is included, not just the popular stuff during landing that has been used over and over. We’ve been jokingly saying that apolloinrealtime.org is the 240-hour cut of the Apollo 11 film. It’s the whole thing.”

A newly discovered hydrothermal field at the northern Gorda Ridge in the Pacific Ocean has been named the Apollo Vent Field in honor of the 50th anniversary of Apollo 11’s Moon landing this July.

The SUBSEA (Systematic Underwater Biogeochemical Science and Exploration Analog) Research Program team aboard Exploration Vessel Nautilus (E/V Nautilus) tagged the feature. Doing so is fitting since the SUBSEA project isn’t just ocean research – it is also an analog project designed to contribute to the future of space exploration.

Off-Earth ocean systems

The Apollo vent field offers a rare glimpse into environments that could be windows into ocean systems elsewhere in our Solar System – on moons such as Saturn’s Enceladus and Jupiter’s Europa.

SUBSEA is a partnership between NASA Science Mission Directorate’S PSTAR Program, NOAA Office of Ocean Exploration and Research, Ocean Exploration Trust, and multiple academic research centers.

NASA’s Planetary Science and Technology from Analog Research (PSTAR) program addresses the need for integrated interdisciplinary field experiments as an integral part of preparation for planned human and robotic missions.

Darlene Lim, served as senior scientist on the Apollo Vent Field investigation. Lim is from NASA Ames/Bay Area Environmental Research Institute (BAERI).

Seafloor activity

The target of the 2019 SUBSEA expedition was the Gorda Ridge, discovered offshore of northern California and Oregon.

This section of mid-ocean ridge is of interest to ocean researchers in that it hosts seafloor hydrothermal activity that departs from the convention of “black smoker” hydrothermal systems.

The focus of exploration was the SeaCliff hydrothermal field, which has previously been reported to emit clear fluids at temperatures no greater than 300°C. The emphasis of the dive was on locating the SeaCliff hydrothermal field for the first time in roughly 15 years and then carry out geological reconnaissance of the site to identify its current size and shape and the number of vents present and the range of temperatures for those vents.

Teleoperations

The SUBSEA Science team utilizes remotely operated underwater vehicles (ROVs) to observe, survey, gather instrument data, and collect samples from analog environments that mimic potential volcanic hydrothermal systems on other ocean worlds, such as Enceladus.

During the SUBSEA field deployment, researchers tested technology and scientific procedures necessary for crewed space exploration. A human-robotic mission to the Moon or Mars might parallel SUBSEA’s mission architecture using robotic explorers controlled by humans nearby, receiving direction from a remote team of scientists.

Ultimately, the results of SUBSEA’s research can inform both strategies for conducting science via teleoperations at destinations such as the Moon or Mars and scientists’ understanding of a wider range of deep-sea environments for conducting ocean world research.

The SUBSEA team work at the Gorda Ridge built upon the work conducted during the first field program at Lō`ihi Seamount off Hawai’i in 2018.

The E/V Nautilus is operated by the non-profit organization Ocean Exploration Trust, founded in 2008 by Robert Ballard to engage in pure ocean exploration.

How much did this footprint cost? Credit: NASA

The Planetary Society has released a new Apollo cost analysis, reporting that the effort would cost nearly $300 billion in today’s dollars. The analysis comes in advance of the 50th anniversary of the Apollo 11 Moon landing.

As explained in the analysis, the United States spent $264 billion on Project Apollo when adjusted to today’s dollars.

Annual budget

The new analysis by Casey Dreier, The Planetary Society’s Senior Space Policy Adviser, spotlights that the total cost of the lunar effort grows to $288 billion when Project Gemini and the related robotic programs are included.

The United States spent an average of $24 billion per year for Apollo between 1961 and 1972—larger than NASA’s entire current annual budget of $21.5 billion.

Resource pages

In addition to the new cost analysis, The Planetary Society also released mission summary resource pages for each Apollo mission.

These mission pages collate high-quality information including per-mission costs, major event timelines, memorable photographs, and links to historical sources such as press kits, videos, and flight journals.

NASA’s Curiosity Mars rover is now performing Sol 2437 duties.

“We are investigating the ridges which are such a prominent feature in this section of Glen Torridon,” reports Catherine O’Connell, a planetary geologist at the University of New Brunswick; Fredericton, New Brunswick, Canada.

“The ridges appear to be composed of sand and pebbles, capped with layered bedrock. The Rover Planners (RPs) at JPL assessed the ridge imaged, known as ‘Teal,’ and gave a go for driving up onto it,” O’Connell adds.

Two drives

The ascent by the rover was broken into two drives. “The RPs got us exactly to where we wanted to be for this plan, and we ended up on a very small outcrop of more coherent bedrock, surrounded by pebbles and sand,” O’Connell points out. “Those of us in the Geology theme group were very excited to find ourselves here, as this is the most substantial piece of bedrock we have seen this week.”

Curiosity’s Alpha Particle X-Ray Spectrometer (APXS) will analyze the “Iapetus” target on the bedrock, and do a 2-point raster “Almond” across small grey pebbles and sand.

The rover was too close to Iapetus to allow the robot’s Chemistry and Camera (ChemCam) to shoot it with the Laser-Induced Breakdown Spectroscopy (LIBS) laser without danger to the rover, O’Connell notes, so ChemCam focused on documenting pebbles here, looking at the targets “Angus,” “Braan,” and “Tweed.” A Mastcam multispectral image, using multiple filter types, will examine spectral variability of the pebbles and sand between Tweed and Almond.

Rubbly material

“Before climbing up onto the ridge, Mastcam will take some color imagery, looking at the rubbly material in the lower part of the ridge,” O’Connell reports, “and documenting the transition from the rubbly material to the capping material.”

Curiosity’s drive will hopefully take scientists bedrock, and once there, will acquire imagery (Mastcam and Navcam) of the rover’s new workspace and future drive direction, to be ready for a full week of exploration on top of this ridge when the robot comes back after the weekend.

“Mastcam will also get a post-drive image of the workspace under one of our wheels, as part of a long-running observation of bedrock, pebbles, and soils along our traverse,” O’Connell says.

Environmental sensing

The Environmental theme group (ENV) planned paired Mastcam observations for each sol of the plan, to determine the amount of dust in the crater (“crater rim extinction” measurements) and to measure the optical depth of the atmosphere and constrain aerosol scattering properties (“full tau” measurements).

The Rover Environmental Monitoring System (REMS) will acquire hourly temperature, pressure, humidity, and UV radiation measurements.

DAN (Dynamic Albedo of Neutrons) continues its search for subsurface hydrogen, with frequent passive (utilizing cosmic rays as a source of neutrons to measure hydrogen) and post-drive active (actively shooting neutrons from the rover) measurements.

Cloud movies

“Finally, ENV planned a number of movies, used to document clouds and dust devils,” O’Connell concludes. “Zenith” cloud movies look upwards, whilst “suprahorizon” movies look at clouds and variations in optical depth in a more horizontal direction.

“Dust devil movies can give information on surface heating and winds near the surface,” O’Connell adds.
