House Budget Looking Better for NASA

The Planetary Society has provided a nice summary of where the NASA funding battle is at this moment. Here is its latest summary of events:

  • The House budget bill that includes NASA funding just cleared a key hurdle, advancing out of the Appropriations Committee. This is the first funding bill for FY 2027 to be released and reach this stage, establishing congressional intent and rejecting the worst of the Office of Management and Budget’s proposed cuts to NASA.
  • The bill keeps NASA funding flat with the currently enacted budget, but reprioritizes funding levels across the agency, including a 17% cut to Science to offset increases elsewhere.
  • A number of science missions proposed for cancellation by the OMB see their funding protected by this bill, including OSIRIS-APEX, New Horizons, and the Chandra X-Ray Observatory. New programs initiated by Administrator Isaacman that were absent from the OMB proposal, like Space Reactor-1 Freedom, also see their first dedicated mention in the proposal.
  • The full House still needs to vote on this, and the Senate is expected to release its own proposal within weeks. Congress will then work to develop full-year funding, in anticipation of the start of FY 2027 on Oct. 1, but will likely require a short-term funding patch, which comes with its own hurdles.

I recommend you read the entire statement, House Appropriators Advance Key NASA Funding Bill, to fully understand the rigors of this Hill battle. Fortunately, both the House and Senate continue to be supportive of NASA’s work and Administrator Isaacman’s new direction for Artemis. It helps to have someone full time at the helm of the agency.

I was especially pleased to read that missions such as New Horizons and the Chandra X-Ray Observatory are being saved and key programs like the James Webb Space Telescope and the Hubble Space Telescope are no longer facing drastic cuts. It is unfortunate that the White House was so willing to destroy generations of space-related work – what have been called the crown jewels of our space program.

The budget battle is not over, but we are seeing that when good legislators push back, good things can happen.

Pic of the Week: Spiral Arm of Galaxy M51

This week’s image is from the James Webb Space Telescope (JWST) and Hubble Space Telescope, which together scanned about 9,000 star clusters in the four galaxies. What you are looking at above comes from the spiral arm of one of the galaxies – Messier 51 (M51).

Here is a description from the European Space Agency (ESA) regarding what you are seeing in the image:

A large, long portion of one of the spiral arms in galaxy M51. Red-orange, clumpy filaments of gas and dust that stretch in a chain from left to right comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small stars. A faint blue glow around the arm colours the otherwise dark background.

Space Stories: New Artemis II Photos, JWST Studies Exoplanet Surface, and Japanese Space Sake for Sale

Here are some recent space-related stories.

—ABC News: “NASA Releases More Than 12,000 Images from Historic Artemis II Moon Mission“

Over the weekend, NASA made public more than 12,000 photos from the historic Artemis II lunar mission…Over the course of the mission, NASA released dozens of images of the astronauts, Earth, the moon and even a total solar eclipse. However, the new trove reveals some never-before-seen photos as well as new angles of objects in space, primarily using Nikon cameras and iPhone 17s.

—ZME Science: “Astronomers Determine the Surface of a Rocky Planet Beyond Our Solar System for the First Time“

A rocky planet nearly 50 light-years away appears to be airless, dark, and covered in volcanic or weathered rock, according to new observations from the James Webb Space Telescope. This is the first time that astronomers have obtained details about the surface of a rocky planet outside our solar system. The planet, LHS 3844 b, is not habitable. It is about 30 percent larger than Earth, orbits its star every 11 hours, and has one side permanently pointing towards the Sun, baked at about 725°C.

—The Korean Times: “Space-fermented Sake by Japanese Brewer Dassai Sells for $700,000“

Japanese brewer Dassai has sold a 100-milliliter bottle of sake fermented on the International Space Station for 110 million yen ($700,000). Dassai partnered with Mitsubishi Heavy Industries to ferment sake ingredients in space, the Yomiuri Shimbun newspaper reported Monday. Using the space-fermented mash, or moromi, the brewery finished brewing the sake on Earth, yielding 116 milliliters. Dassai sold a 100-milliliter bottle of the final product to an unnamed Japanese buyer. The company plans to donate the proceeds to Japan’s space program.

Study Findings: A Second Visit to Eps Ind Ab with JWST: New Photometry Confirms Ammonia and Suggests Thick Clouds in the Exoplanet Atmosphere of the Closest Super-Jupiter

The Astrophysical Journal Letters abstract of study findings:

With JWST, we are directly imaging cold (∼200–300 K) solar-age giant exoplanets for the first time. At these temperatures, many molecular features appear, and water-ice clouds may condense and affect the emission spectrum; early photometric measurements of cold giant planets are already showing some tension with the predictions of cloud-free solar-metallicity atmosphere models. Here, we present new JWST/MIRI coronagraphic observations of the cold giant exoplanet Eps Ind Ab at 11.3 μm. Together with archival data, we use these new observations to study the atmosphere of this cold exoplanet, and we also refit its orbit, finding an updated mass of 7.6  ±  0.7MJup and an eccentricity of 0.24 +0.11/-0.08. The planet is significantly brighter (by 0.88  ±  0.08 mag) at 11.3 μm than at 10.6 μm, indicating the presence of ammonia. However, this ammonia feature is shallower than expected. This could indicate a low-metallicity or nitrogen-depleted atmosphere, but our preferred explanation is the presence of thick water-ice clouds that suppress the ammonia feature and the near-IR emission of Eps Ind Ab. Photometry of the small but growing sample of cold giant exoplanets demonstrates that they are consistently fainter than expected between 3 and 5 μm, consistent with the water-ice cloud hypothesis. 10.6 μm and 11.3 μm photometry of this cold exoplanet sample would be valuable to determine whether the suppressed ammonia feature is universal, and to frame a new open question about the underlying physical cause.

Pic of the Week: Multiple Views of Saturn

This week’s images of Saturn from 2024 were just released by NASA. They show the planet in a variety of ways, depending on the telescope and instruments being used. The James Webb Space Telescope (JWST or Webb) and Hubble Space Telescope each have their own unique abilities that can bring the distant gas giant to life.

In its comments on the two images above, NASA noted:

Together, scientists can effectively ‘slice’ through Saturn’s atmosphere at multiple altitudes, like peeling back the layers of an onion. Each telescope tells a different part of Saturn’s story, and the observations together help researchers understand how Saturn’s atmosphere works as a connected three-dimensional system. Both complement previous observations done by NASA’s Cassini orbiter during its time studying the Saturnian system from 1997 to 2017...These 2024 observations, taken 14 weeks apart, show the planet moving from northern summer toward the 2025 equinox. As Saturn transitions into southern spring, and later southern summer in the 2030’s, Hubble and Webb will have progressively better views of that hemisphere.
