—Universe Space Tech: “The Earendil-1 Satellite, Equipped with its Large Mirror, Has Caused Discontent Among Astronomers“

The United States Federal Communications Commission (FCC) has granted approval to Reflect Orbital to proceed with testing its innovative Earendil-1 satellite. This spacecraft features a substantial mirror engineered to redirect sunlight towards the nighttime side of Earth. The primary objective of the startup is to augment energy supply to solar power facilities and illuminate extensive regions up to 5 kilometers in width. By the year 2035, the company intends to deploy a constellation comprising 50,000 such orbital reflectors. Notwithstanding the potential advantages for agriculture and emergency services, the initiative has elicited grave concerns within the community.

—CBS News “Astronomers Discover Sugar in Space That’s Also Found in Raspberries: ‘Just Floating Out in the Galaxy‘”

The space between stars just got a little sweeter. Astronomers have detected a type of sugar in space that’s also found in raspberries and self-tanners. The sugar, called erythrulose, lurks in what’s called the interstellar medium: thin clouds of gas and dust littered between stars. Sugar does more than sweeten tea and powder doughnuts. Different varieties fuel our cells and even make up DNA. Scientists are itching to know how sugars form because they’re a key ingredient for life as we know it.

—Science Alert: “Vantablack: World’s Blackest Paint Could Solve A Major Problem For Astronomy“

Low Earth orbit is becoming increasingly crowded with satellites, and they’re quietly erasing our view of the Universe…Chaturvedi and a team of researchers in the UK think they might have the answer: Vantablack 310, a specific formulation of one of the blackest materials ever developed, intended for use on spacecraft. In lab tests, coating satellites with Vantablack 310 meant that only 2 percent of incoming light was reflected.

Space Stories: Starliner Beats SpaceX on Costs, NASA Administrator Ignores Regulators, and Blue Origin Rebuilding Beyond Impressive

Posted on by onespaceman2000

Here are some recent NASA-related stories of interest.

—Florida Sentinel: “Boeing Starliner Costly But Cheaper for NASA Than SpaceX Switch, Audit Says“

Boeing’ Starliner costs and delays remain the target of the latest audit from NASA’s Office of the Inspector General, but remains a cheaper option for the agency than relying solely on SpaceX for its commercial crew needs. The audit releasedJune 30 dinged the beleaguered spacecraft’s tumultuous and still uncertain path toward certification and wars that the timetable for its use to ferry astronauts to and from the International Space Station is running short.

—Newser: “NASA Chief Defies FAA With ‘High-Risk’ Flight“

NASA chief Jared Isaacman took to the skies over Washington in a vintage fighter jet on July 4, even after federal regulators flagged the plan as too risky. The Federal Aviation Administration rejected a request on June 30 to let four 1970s-era Northrop F-5 Tiger II jets participate in the National Mall flyover for America’s 250th birthday, calling the aircraft “very high-risk” and citing concerns about flight controls, ejection scenarios, and past crashes, the Wall Street Journal reports.

—Benzinga: “NASA’s Jared Isaacman Says Blue Origin’s New Glenn Recovery Is ‘Beyond Impressive’“

NASA Administrator Jared Isaacman said Blue Origin has devoted significant resources to cleaning up and rebuilding its launch pad after a late-May explosion of a New Glenn rocket, as the agency weighs how the setback could affect lunar missions tied to the Artemis program. “Blue Origin’s response to the situation is almost beyond impressive, and that’s not just a NASA assessment,” Isaacman told reporters Wednesday afternoon, according to Ars Technica. He said U.S. Space Force officials also have been deeply involved in Blue Origin’s planning since the May 28 test anomaly damaged New Glenn’s only operational launch pad.

—Science Alert: “Heads Up: NASA to Launch ‘Daring’ Telescope Rescue Mission This Week“

NASA will soon attempt something it’s never done before: Save a space telescope from falling back to Earth using a servicing robot. It sounds like something right out of a sci-fi film, but NASA is hoping it might be enough to keep its sinking Neil Gehrels Swift Observatory in action a little longer. According to the US space agency, the mission could launch as soon as this Tuesday 30 June, 6:17 am EDT (10:17 UTC), and we’ll be keeping you updated on the progress. If this mission works, the much-beloved Hubble Space Telescope is one of the next targets to have its life extended.

—The National News: “Stellar Places to Watch the Night Sky Across the Arab World“

Saudi Arabia has announced plans for AlUla Manara, a major astronomical observatory and research centre in the kingdom’s north-west…AlUla Manara is planned to include large telescopes, observation platforms, exhibitions, interactive experiences, a planetarium, a restaurant and a visitor and research centre. The project is intended to support scientific research as well as public astronomy experiences. No opening date has been announced.

—MSN: “Ukraine Strikes Russian Space Hub as Nuclear Orbit Fears Grow“

Ukraine’s General Staff confirmed its forces struck the Vladimir Space Communications Center near Gus-Khrustalny on 22 June, destroying the main 25‑metre parabolic antenna, damaging satellite modem halls, multiplexers, and cooling systems. Additional damage to the Main Hardware and Software Complex and a key technical building severely degraded Russia’s satellite operations…The Vladimir facility plays a central role in Russia’s satellite communications, and its loss comes amid accusations that Moscow has manoeuvred satellites near European systems used by Ukraine, causing GPS disruption across Europe, Greenland, and Canada.

—Techcrunch: “NASA Picks Eric Schmidt’s Rocket Company for Mars Mission, Setting Up a Race with SpaceX“

Relativity Space — a rocket maker acquired by former Google executive chair Eric Schmidt last year after stumbling on the path to orbit — might just beat SpaceX to Mars. On Tuesday, NASA said it hired the company to build a spacecraft to house a suite of scientific instruments, launch it into space, and fly it to Mars. The structure of the contract is akin to the deals that NASA made with SpaceX to fly cargo to the International Space Station, or Firefly Aerospace to put a lander on the moon. The government agency handles the science, while the private company provides low-cost infrastructure.

—Universe Today: “Astronomers Want to Build a Swarm of Telescopes to Find LIFE“

Current plans for flagship telescopes in the 2040s are focused on answering a simple question – are we alone? Our best telescopes to date, such as the James Webb Space Telescope (JWST) have only given us tantalizing glimpses into the atmospheres or other worlds, but not enough to truly determine whether or not life as we know it exists there. Astronomers have been waiting for technology to catch up to their dreams of what is possible in terms of new types of telescopes, and recently the W.M. Keck Institute for Space Studies released a report detailing the Large Interferometer For Exoplanets (LIFE) mission, which they hope will help provide a definitive answer to that simple question.

—BBC Sky at Night: “The Pink Planet is So Weird, Astronomers Struggle to Define It. And They’ve Just Found It’s Covered in Salty Clouds“

There’s a pink planet, just a stone’s throw from Earth, that astronomers have been trying to decipher for over a decade. Known as the Pink Planet or, officially, GJ504b, this strange world orbits a Sun-like star 57 lightyears from Earth. Astronomers aren’t even sure if it’s a planet at all. About 25 times the mass of Jupiter, it’s so massive it’s on the boundary between giant planets and brown dwarfs (a type of failed star). But observations with the James Webb Space Telescope have revealed direct evidence for something rather strange at the Pink Planet: salty clouds.

—Satnews: “Pittsburgh’s Moonshot: Astrobotic Unveils Griffin-1 Lander Ahead of Historic NASA ‘Moon Base II’ Mission“

Emerging as a powerful symbol of regional industrial pride and the rapid privatization of deep-space logistics, Astrobotic Technology has officially unveiled its massive Griffin-1 lunar lander. The vehicle, which has been formally designated by NASA as the primary infrastructure vehicle for the Moon Base II task order under the Commercial Lunar Payload Services (CLPS) program, represents a critical stepping stone toward establishing a permanent, self-sustaining human presence on the lunar surface. Unlike smaller, first-generation commercial scouts, the Griffin platform is an “infrastructure-class” logistics vehicle engineered to transport heavy industrial cargo. Boasting a massive 625 to 650-kilogram payload capacity, the stout aluminum isogrid lander is designed to ferry bulky machinery, scientific sensor arrays, and alternative energy installations directly to the rugged, hazardous terrain of the lunar south pole.

—Newser: “Giant Nevada Project Could Transform Astronomy“

Caltech has approved the final design for the Deep Synoptic Array, a $200 million radio telescope project that will blanket a chunk of desert with 1,650 dishes over roughly 120 square miles—an array designed to scan the sky about 100 times faster than any existing telescope. Backed in part by Schmidt Sciences, the philanthropic effort of former Google CEO Eric Schmidt and his wife Wendy, the project is slated to be finished by 2029 and will be powered by a supercomputer that turns torrents of radio signals into sharp images on the fly.

—W.M. Keck Observatory: “Astronomers Discover Third Galaxy Without Dark Matter“

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island, have discovered the third known galaxy apparently lacking dark matter, part of a strange linear structure that may have formed during a violent collision between galaxies. The discovery strengthens evidence for a rare and previously unseen process in which ordinary matter becomes separated from dark matter, offering astronomers a powerful new way to study one of the universe’s greatest mysteries.
