JWST: It Can Be Dangerous in Space

NASA reports that the James Webb Space Telescope (JWST) was hit by a micrometeroid last month. The tweet from NASAWebb stated:

In late May, Webb sustained a dust-sized micrometeroid impact to a primary mirror segment. Not to worry: Webb is still performing at a level that exceeds all mission requirements.

A second story explained how NASA tested the JWST for just such instances, though the final sentence was a little more worrisome:

Webb’s mirror was engineered to withstand bombardment from the micrometeoroid environment at its orbit around Sun-Earth L2 of dust-sized particles flying at extreme velocities. While the telescope was being built, engineers used a mixture of simulations and actual test impacts on mirror samples to get a clearer idea of how to fortify the observatory for operation in orbit. This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground.

And this sentence is also worrisome:

Since launch, we have had four smaller measurable micrometeoroid strikes that were consistent with expectations and this one more recently that is larger than our degradation predictions assumed. 

The $10 billion space telescope, which is still working to become operational, is not expected to share images until mid-July. Unlike the Hubble Space Telescope, NASA cannot send astronauts out to the JWST to make periodic repairs. The JWST currently sits in the L2 Lagrange point about 1 million miles away. All NASA can do now is try to compensate for the damage as best it can.

A New Suit for the Moon Mission

U.S. companies Axiom Space and Collins Aerospace have been tasked to build new suits for NASA’s astronauts. The suits will be worn as part of the Artemis Program returning astronauts to the Moon. First, the new suits will be tested and used on the International Space Station (ISS).

While both companies are still in the early stages of developing the next space suite, the $3.5 billion Extravehicular Activity Services (xEVAS) Contract will support this development and production.

In a press release, Mark Kirasich, deputy associate administrator of NASA’s Artemis Campaign Development Division, stated:

Our commercial partnerships will help realize our human exploration goals…We look forward to using these services for NASA’s continued presence in low-Earth orbit and our upcoming achievement of returning American astronauts to the Moon’s surface. We are confident our collaboration with industry and leveraging NASA’s expertise gained through over 60 years of space exploration will enable us to achieve these goals together.

You may recognize the name Axiom Space. It was the company that worked with SpaceX to put private citizens on the ISS with its Axiom Mission 1 (Ax-1). It is also developing the world’s first commercial space station, the Axiom Station.

Collins Aerospace, part of Raytheon Technologies, has plenty of experience with space suits. The company designed the spacesuit used by the Apollo mission astronauts who landed on the moon. It also designed the space suits currently in use for missions outside the ISS.

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.
