NASA has recently chosen four proposals for concept studies of missions to help advance our understanding of key areas in Earth science. These missions will focus on topics such as greenhouse gases, the ozone layer, ocean surface currents, and changes in ice and glaciers around the world.

The selection of these proposals is part of NASA’s Earth System Explorers Program, which conducts space science missions based on recommendations from the National Academies of Sciences, Engineering, and Medicine. The program aims to enable high-quality Earth system science investigations focused on previously identified targets. In this case, NASA is prioritizing the study of greenhouse gases.

Nicky Fox, associate administrator of NASA’s Science Mission Directorate, emphasizes the importance of these proposals in the face of our changing climate. As we continue to confront the challenges posed by climate change, the need for data and scientific research becomes even more crucial. These proposals will help us better prepare for the present and future challenges we face.

The first step in the selection process involves each of the chosen proposals receiving $5 million for a one-year mission concept study. After this study period, NASA will select two proposals to move forward with, expecting to launch these missions in 2030 and 2032. The total cost for each selected investigation is capped at $310 million, not including the rocket and access to space, which will be provided by NASA.

NASA has been at the forefront of Earth observations for over 60 years, and most of our current knowledge about our changing planet comes from these observations. With over two dozen Earth-observing satellites and instruments currently in orbit, the missions ultimately chosen from these proposals will contribute to this vast Earth observatory. Together, these missions provide complementary information on Earth’s oceans, land, ice, and atmosphere.

Let’s take a closer look at the four proposals selected for concept studies:

  1. The Stratosphere Troposphere Response using Infrared Vertically-Resolved Light Explorer (STRIVE):
    Led by Lyatt Jaegle at the University of Washington in Seattle, this mission aims to provide high-resolution measurements of temperature, atmospheric elements, and aerosol properties from the upper troposphere to the mesosphere. It also seeks to measure ozone and trace gases to monitor and understand the recovery of the ozone layer.
  2. The Ocean Dynamics and Surface Exchange with the Atmosphere (ODYSEA):
    Led by Sarah Gille at the University of California in San Diego, this satellite mission aims to measure ocean surface currents and winds simultaneously. By improving our understanding of air-sea interactions and surface current processes, ODYSEA will contribute to our knowledge of weather, climate, marine ecosystems, and human well-being.
  3. Earth Dynamics Geodetic Explorer (EDGE):
    Led by Helen Amanda Fricker at the University of California in San Diego, this mission focuses on observing the three-dimensional structure of terrestrial ecosystems and the surface topography of changing glaciers, ice sheets, and sea ice in response to climate change and human activity. EDGE aims to continue the measurements currently taken by ICESat-2 and GEDI.
  4. The Carbon Investigation (Carbon-I):
    Led by Christian Frankenberg at the California Institute of Technology in Pasadena, this investigation seeks to measure greenhouse gases and potentially quantify ethane simultaneously. By providing unprecedented spatial resolution and global coverage, Carbon-I will contribute to our understanding of the carbon cycle and the global methane budget.

These selected proposals represent NASA’s commitment to advancing our understanding of Earth’s changing climate. With these missions, NASA continues to play a crucial role in providing the data and scientific research needed to tackle the challenges we face today and in the future.

Asteroid


As we gaze up at the night sky, pondering the vastness of the universe, an intriguing event is set to unfold: a football field-sized asteroid is making its way past Earth tomorrow. Named 2006 WB, this celestial traveler is estimated by NASA’s Jet Propulsion Laboratory (JPL) to be about 310 feet across, although its size could range anywhere from 240 to 525 feet. For perspective, a football field measures approximately 360 feet in width, making this asteroid a formidable presence as it skims by our planet.

Approaching Asteroid

At a distance of 554,000 miles—roughly twice the distance to the Moon—2006 WB will pass by us at a speed of about 4.2 km/s, or approximately 9,400 mph. This velocity is several times faster than a bullet fired from a rifle, which can travel up to around 2,700 mph. While 554,000 miles may sound distant, it is remarkably close on a solar system scale, especially when compared to our neighboring planet Venus, which can be about 24 million miles away at its closest approach.

In addition to 2006 WB, there are four other asteroids making their own close passes in the coming days. Today, two bus-sized asteroids, 2024 WF2 and 2024 WJ3, will soar past Earth at distances of 1,780,000 miles and 2,780,000 miles, respectively. Following them, the plane-sized 2009 WB105 will come within 3,600,000 miles, and on Tuesday, another bus-sized asteroid, 2024 WD3, will pass at around 1,080,000 miles.

Jay Tate, director of the United Kingdom’s Spaceguard Centre observatory, highlights that asteroids are frequently zipping past Earth, often without much public awareness. 2006 WB falls into the category of Near-Earth Objects (NEOs), defined as objects that come within 30 million miles of our planet. NEOs are monitored closely, with over 34,000 identified in our solar system, and the JPL’s Center for Near-Earth Object Studies (CNEOS) actively tracking at least 2,300 potentially hazardous asteroids (PHAs).

While the odds of a large asteroid impacting Earth are exceedingly low, the consequences of such an event could be catastrophic. Svetla Ben-Itzhak, an assistant professor of space and international relations at Johns Hopkins University, warns that a cosmic body of 460 feet in diameter could obliterate an entire city and wreak regional havoc. In contrast, larger objects exceeding 1 kilometer in diameter could have far-reaching global implications, potentially leading to mass extinction.

Fortunately, the asteroids currently making their approach, including 2006 WB, do not fall within the category of potentially hazardous objects due to their size and the distances they will maintain from our planet. As we continue to advance our understanding of these celestial bodies, the importance of tracking and monitoring NEOs remains paramount for the safety of humanity.

That year LA declared it was at “Peak Car!”

Published

on

Peak Car
Los Angeles County Metropolitan Transportation Authority

Was there a time it was considered that “The City of Angeles,” had reached “Peak Car?”

I recently came across an article posted by the Metro Digital Resources Librarian on the Dorothy Peyton Gray Transportation Library and Archive web site run by Metro Los Angeles. The article talked about LA’s new obsession with the automobile and how it gained popularity, in the early 1920s.

Peak Car Era

Library researchers pointed out that notable resources concurred with this, including Scott L. Bottles’ Los Angeles and the Automobile: The Making of the Modern City, and Ashleigh Brilliant’s The Great Car Craze, How Southern California Collided with the Automobile in the 1920s.

The automobile was new and fresh, and also offered freedom to its owners, who realized that they could become more mobile and not rely solely on the massive LA street car network at the time.  The number of vehicle registrations in Los Angeles had quadrupled in just an eight-year period from 1914-1922.

“Automobile use exploded as the passenger vehicle transitioned from a hobbyist’s pursuit to a relatively affordable means of getting around the sprawling region and beyond.”

Metro Librarian found out what was happening on the public transit side of the story when they found an article published in Electric Railway Journal titled “California and Her Tractions, Part II.

MetroDigital Resource Librarian:

As one of several features titled “A Series of Articles on Salient Phases of the Electric Railway Situation,” author Edward Hungerford details the then current state of public transit in the Los Angeles area.

And within that overview, he interviews Paul Shoup, Pacific Electric Railways president and vice-president of Southern Pacific Company.

Hungerford documents Pacific Electric’s earnings in a recent six-month period, and asks Shoup “for the real translation of these figures.”

Shoup responds by stating:

They mean that the peak of the competition of the automobile, publicly or privately owned or operated, has been reached out here — and passed. Not only is the rapidly rising cost of cars and tires and gasoline and oil beginning to deter the overenthusiastic motorists, but I think that the novelty of excessive motor riding also is rather wearing off. The hazards of driving on crowded highways are becoming more apparent and parking spaces in towns and cities more a question of doubt.

In addition to our great numbers of motor stage routes in every direction, we now have some 500,000 automobiles in California licensed for pleasure purposes, to which should be added the cars owned and operated by the 100,000 Easterners who come out here every winter. The competitive effect of all these cars has been, and still is, vast indeed. But we already can see in it a declining curve.

Yes, you read that right, Shoup declared that personal vehicle usage had peaked and that it was on the decline.

Shoup explains that Los Angeles Railway profits were consistent with those of Pacific Electric, but acknowledges that “increases in both operating cost and taxes had gone ahead a little more than proportionately.” But he intimates that the rising cost of automobile operation (gas, tires) means that cars will cease their encroachment into transit’s share of mobility.

This statement was part of an interview published in a national journal. Was he telling industry professionals what they wanted to hear? Did he want to assuage fears of rail employees that their jobs were going to disappear as more people purchased and used automobiles? Was he hoping that his perspective would turn into a self-fulfilling prophecy so he could remain atop Pacific Electric and Southern Pacific?
