Here are some recent space-related stories of interest.

—WTOP News: “NASA Opens its First Wind Tunnel in 40 Years at Langley Research Center“

Friday was a historic day for NASA’s Langley Research Center in Hampton, Virginia. A stellar lineup of VIPs from NASA, GSA, Congress, Virginia and Langley employees celebrated the ribbon-cutting ceremony for NASA’s newest and most advanced wind tunnel: the Flight Dynamics Research Facility. The $53 million, 25,000-square-foot FDRF, built by BL Harbert International, is the first wind tunnel added to NASA’s wind tunnel assets in 40 years. The project was started in June 2022, with construction completed in March 2026.

—NASA: “NASA’s Roman Telescope to Carry 1.35 Million Names to Deep Space“

On July 27, technicians at NASA’s Kennedy Space Center in Florida installed a memory card containing 1,350,144 names as part of a commemorative plaque on the Nancy Grace Roman Space Telescope. The names were submitted by people globally, including astronauts from Artemis II and Artemis III. The memory card will travel with the Roman observatory to the Sun-Earth Lagrange point 2, or L2, about one million miles from Earth, where the Sun’s and Earth’s gravity balance out.

—Wired: “Astronomers Have Detected an Exomoon for the First Time“

An international research team has discovered evidence of a moonlike body. It marks the first time such an object has been detected outside our solar system—though just how close it comes to being a moon is a question researchers are still grappling with. Although more than 6,000 exoplanets have been discovered to date, there’s been a lack of definitive evidence of moons in other planetary systems. The new findings challenge that by focusing on an object orbiting the brown dwarf CD-35 2722 B in a system 73 light-years away.

Pic of the Week: Preparing the Nancy Grace Roman Space Telescope

The image above, taken on July 20th, shows one of the many teams working on the Nancy Grace Roman Space Telescope as it gets ready for its launch on August 30th. The pictured individuals are part of the propellant, safety, and quality assurance team.

NASA’s latest update on the mission stated:

Technicians completed fueling NASA’s Nancy Grace Roman Space Telescope, bringing it an important step closer to launch. On July 25, the team completed operations that carefully loaded 290 gallons of hydrazine fuel into the observatory at the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida.

After launch and separation from the rocket, Roman will use this onboard propellant to perform maneuvers as it travels to Sun-Earth Lagrange point 2, or L2, located about one million miles from Earth. There, about four times the distance to the Moon, it will have an ideal home for astronomy.

The New Glenn Launch to Mars Scheduled for Tomorrow

Blue Origin’s New Glenn rocket is scheduled to be launched tomorrow afternoon with two Martian probes on board. A lot is riding on tomorrow’s launch. The mission is important for Blue Origin, as it tests its new rocket with its first real mission. It is also important to NASA, which is using the probes to better understand the Martian atmosphere.

Blue Origin’s reusable New Glenn rocket will put it in direct competition with SpaceX for future NASA missions. This redundancy is needed, particularly with SpaceX seeming to struggle with its projects related to the Atemis lunar mission.

The $100 million Martian mission, called Escape and Plasma Acceleration and Dynamics Explorers (EscaPADE), involves a pair of identical spacecraft with a the goal of analyzing:

  1. how Mars’ magnetic field guides particle flows around the planet,
  2. how energy and momentum are transported from the solar wind through the magnetosphere, and
  3. what processes control the flow of energy and matter into and out of the Martian atmosphere.

The two probes will be launched towards Lagrange Point 2, where they will sit for more than a year before making an approach towards Mars. The probes are expected to go into orbit around Mars in September 2027.

Godspeed to Blue Origin and NASA.

Update: The launch has been delayed due to bad weather. The next attempt will be on November 12th.

Space Mission: ESA’s Euclid Telescope

To follow up on the previous post, Russia also lost out on launching the European Space Agency’s (ESA) Euclid spacecraft. Russia was supposed to launch it on a Soyuz-ST/Fregat rocket this December, but the country’s invasion of Ukraine led to a change in plans. SpaceX will now be launching the spacecraft next year.

Euclid was designed to study dark energy and dark matter, and make a 3D-map of the Universe. The project includes scientists from 14 countries: Austria, Denmark, France, Finland, Germany, Italy, Netherlands, Norway, Spain, Switzerland, Portugal, Romania, the UK, and the US.

Euclid hopes to answer the following questions:

  • How did the Universe originate? What were the conditions just after the Big Bang, and how did these give rise to the large-scale structures we see today?
  • Why is the Universe expanding at an accelerating rate today?
  • Is dark energy – a term often used to signify the mysterious force behind this cosmic acceleration – real? If so, is it a constant energy density intrinsic to and spread throughout space, or a new force of nature that slowly evolves as the Universe expands?
  • What is the nature of dark matter, and how do neutrinos possibly contribute? Are there other as-yet-undetected massive particles in the Universe?

Once launched, Euclid will operate in the Sun-Earth Lagrange point 2 (L2), which is where the James Webb Space Telescope is located as well as ESA’s Gaia spacecraft. Gaia, launched in December 2013, is currently mapping the stars in the Milky Way galaxy. It seems L2 is the place to be.

NASA is contributing infrared flight detectors for one of Euclid’s two science instruments. You can read more about the NASA contribution here.

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.
