NASA’s FY 2023 Budget Request

So what else did NASA Administrator Bill Nelson share with the Senate Committee on Appropriations last week (beyond his comments about the International Space Station)? In his prepared statement regarding NASA’s $26 billion budget request, he highlighted a number of priorities for his agency, including:

  • the Artemis Program to bring astronauts back to the Moon and related exploration costs – $7.5 billion;
  • continued support for the ISS – $4.3 billion;
  • the space technology research and development portfolio for the Moon, Mars, and other areas, such as sending the CAPSTONE CubeSat to the Moon as a pathfinder for the Artemis program – $1.44 billion;
  • greater science funding for projects such as exploring solutions for bringing the samples of Martian rock and soil collected by the Perseverance rover to Earth through the Mars Sample Return mission – $8 billion; and
  • supporting the civil aviation manufacturing sector with test flights on its Low Boom Flight Demonstrator, which will enable environmentally and socially acceptable supersonic passenger flights, as well as continued work on the X-57 Maxwell, an all-electric aircraft – $971 million.

NASA certainly has a lot on its place, and I did not even highlight the focus on Earth iteself, such as the planned Earth System Observatory, which is an array of satellites, instruments, and missions designed to generate a 3D, holistic view of the entire planet.

We just provided a $40 billion aid package to Ukraine so that it can defend itself and have a better future. This $26 billion will take us out of the realm of Earth-bound conflicts and allow us to find our future in the stars, or at least the solar system. It is money well spent.

World’s First Liquid Mirror Telescope

An earlier post mentioned NASA’s plans for a liquid mirror telescope in space. Well, India now has one here on Earth.

The Indian Express reports that the liquid mirror telescope was designed and built at the Advanced Mechanical and Optical Systems Corporation and the Centre Spatial de Liege, Belgium. While funded by Canada and Belgium, it will be maintained and operated by India. The article states:

India’s first liquid-mirror telescope, which will observe asteroids, supernovae, space debris and all other celestial objects from an altitude of 2,450 metres in the Himalayas, has seen its first light. It has now entered the commissioning phase and will start scientific observations some time in October this year.

Liquid mirror telescopes have a few advantages, including being inexpensive to build and providing a very efficient way to image a large area of the sky. A disadvantage is that such a telescope must lie flat on Earth and can only observe what passes overhead (unlike space where the lack of gravity may offer other options). Even so, India expects to obtain plenty of information using this new form of telescope.

A new way to view the heavens. This may be the start of something pretty amazing.

International Space Station: Russians Still Busy

Earlier today, NASA announced that an uncrewed Russian cargo ship, Progress 81, arrived at the International Space Station (ISS) without incident. Work continues among the Americans and Russians aboard the ISS regardless of the situation on the ground, which is reassuring.

As NASA administrator Bill Nelson said last month at a Senate Appropriations Committee hearing, there have been a number of “misleading headlines” about the end of Russia’s participation in the ISS program. He also highlighed how US astronauts were able to work together with Soviets during the Cold war. Specifically, he stated:

I see nothing in the very even-keeled professional relationship between the cosmonauts and the astronauts, between mission control in Moscow and Houston, in the training of Russian cosmonauts in America and the training of American astronauts in Moscow and Baikonur…I see nothing that has interrupted that professional relationship, no matter how awful Putin is conducting a war with such disastrous results in Ukraine.

Pic of the Week:  Gypsum Dunes on Mars

This week’s amazing image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera onboard NASA’s Mars Reconnaissance Orbiter launched in 2005. The University of Arizona’s Lunar & Planetary Laboratory, which operates HiRISE, described the image in this way:

This image suggestion outlines a contact between gypsum-rich dunes in Olympia Undae and flat-lying layers of the basal (or bottom) unit. Our goal is to look for a stratigraphic and compositional comparison between the dunes and the basal unit.

Olympia Undae, the largest continuous dune field on Mars,  is in the northern polar region of Mars.

Whatever Happened to NASA’s Mariner 8?

An earlier post noted the anniversary of NASA’s Mariner 9 spacecraft to Mars, launched on May 30, 1971, but what about Mariner 8? What happened to that Mars bound spacecraft?

Both Mariner 8 and 9 we developed together so one could replace the other if needed, which was pretty smart. The Russians did the same thing with their first trip to Mars in 1971, successfully sending Mars 2 (launched May 19) and Mars 3 (launched May 28).

Mariner 8 was supposed to be the first U.S. spacecraft to orbit Mars. It was launched on May 8, 1971 but never achieved Earth orbit due to a launch vehicle failure. Instead, it fell into the Atlantic Ocean.

Of the 10 Mariner missions, 7 were successfully took space craft to Mars, Venus, and Mercury. Unfortunately, like Mariner 8, Mariner 1 failed after launch. Fortunately, like Mariner 9, Mariner 2 was a back up spacecraft that ensure mission success. Mariner 3 failed after launch because of a battery issue, but its double Mariner 4 was successful. Here are the 10 missions (you can find more about them here):

  • Mariner 1: Venus mission launched on July 22, 1962. — Failed
  • Mariner 2: Venus mission launched on August 27, 1962. — Success
  • Mariner 3: Mars mission launched on November 5, 1964. — Failed
  • Mariner 4: Mars mission launched on November 28, 1964. — Success
  • Mariner 5: Venus mission launched on June 14, 1967. — Success
  • Mariner 6: Mars mission launched on February 25, 1969. — Success
  • Mariner 7: Mars mission launched on February 25, 1969. — Success
  • Mariner 8: Mars mission launched on May 8, 1971. — Failed
  • Mariner 9: Mars mission launched on May 30, 1971. — Success
  • Mariner 10: Mercury and Venue mission launched on November 3, 1973. — Success

While three spacecraft failed, all of the missions were successful because of the redundancy built into the system. We do not seem to have such luxuries anymore, though NASA’s Mars Exploration Rover (MER) mission had two Mars rovers, Spirit and Opportunity, to increase the chances of success.
