Credits: NASA / Morgan Johnson NASA is seeking information from U.S. and international companies about Earth proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging agency science missions.

      “As part of NASA’s Communications Services Project, the agency is working with private industry to solve challenges for future exploration,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN Program. “Through this effort, NASA missions will have a greater ability to command spacecraft, resolve issues in flight, and bring home more data and scientific discoveries collected across the solar system.”

      In November 2024, NASA announced the TDRS (Tracking and Data Relay Satellite) system, the agency’s network of satellites relaying communications from the International Space Station, ground controls on Earth, and spacecraft, will support only existing missions.

      NASA, as one of many customers, will obtain commercial satellite services rather than owning and operating a replacement for the existing satellite system. As NASA transitions to commercial relay services, the agency will leverage commercial capabilities to ensure support for future missions and stimulate private investment into the Earth proximity region. Commercial service offerings could become available to NASA missions as early as 2028 and will continue to be demonstrated and validated through 2031.

      NASA’s SCaN issued a Request for Information on May 30. Responses are due by 5 p.m. EDT on Friday, July 11.

      NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

      What does it take to gaze through time to our universe’s very first stars and galaxies?  
      NASA answers this question in its new documentary, “Cosmic Dawn: The Untold Story of the James Webb Space Telescope.” The agency’s original documentary, which chronicles the story of the most powerful telescope ever deployed in space, was released Wednesday, June 11.
      Cosmic Dawn offers an unprecedented glimpse into the delicate assembly, rigorous testing, and triumphant launch of NASA’s James Webb Space Telescope. The documentary showcases the complexity involved in creating a telescope capable of peering billions of years into the past.  
      Cosmic Dawn is now available for streaming on NASA’s YouTube, NASA+, and select local theaters. The trailer is available on NASA+ and YouTube.
      Relive the pitfalls and the triumphs of the world’s most powerful space telescope—from developing the idea of an impossible machine to watching with bated breath as it unfolded, hurtling through space a million miles away from Earth. Watch the Documentary on YouTube The film features never-before-seen footage captured by the Webb film crew, offering intimate access to the challenges and triumphs faced by the team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland — the birthplace of Webb.
      “At NASA, we’re thrilled to share the untold story of our James Webb Space Telescope in our new film ‘Cosmic Dawn,’ celebrating not just the discoveries, but the extraordinary people who made it all happen, for the benefit of humanity,” said Rebecca Sirmons, head of NASA+ at the agency’s headquarters in Washington.
      From its vantage point more than a million miles from Earth and a massive sunshield to block the light of our star, Webb’s First Deep Field  the deepest and sharpest infrared images of the universe that the world had seen.
      Webb’s images have dazzled people around the globe, capturing the very faint light of the first stars and galaxies that formed more than 13.5 billion years ago. These are baby pictures from an ancient past when the first objects were turning on and emitting light after the Big Bang. Webb has also given us new insights into black holes, planets both inside and outside of our own solar system, and many other cosmic phenomena.
      Webb was a mission that was going to be spectacular whether that was good or bad — if it failed or was successful. It was always going to make history

      NASA’s biggest and most powerful space telescope was also its most technically complicated to build. It was harder still to deploy, with more than 300 critical components that had to deploy perfectly. The risks were high in this complicated dance of engineering, but the rewards were so much higher.
      “Webb was a mission that was going to be spectacular whether that was good or bad — if it failed or was successful,” said video producer Sophia Roberts, who chronicled the five years preceding Webb’s launch. “It was always going to make history.”
      NASA scientists like Nobel Laureate Dr. John Mather conceived Webb to look farther and deeper into origins of our universe using cutting edge infrared technology and massive mirrors to collect incredibly rich information about our universe, from the light of the first galaxies to detailed images of planets in our own solar system.
      To achieve this goal, NASA and its partners faced unprecedented hurdles.
      Webb’s development introduced questions that no one had asked before. How do you fit a telescope with the footprint of a tennis court into a rocket? How do you clean 18 sensitive mirrors when a single scratch could render them inoperable? How do you maintain critical testing while hurricane stormwater pours through ceilings?

      “There was nothing easy about Webb at all,” said Webb project manager Bill Ochs. “I don’t care what aspect of the mission you looked at.”
      Viewers will experience a one-of-a-kind journey as NASA and its partners tackle these dilemmas — and more — through ingenuity, teamwork, and unbreakable determination.
      “The inspiration of trying to discover something — to build something that’s never been built before, to discover something that’s never been known before — it keeps us going,” Mather said. “We are pleased and privileged in our position here at NASA to be able to carry out this [purpose] on behalf of the country and the world.”
      Bound by NASA’s 66-year commitment to document and share its work with the public, Cosmic Dawn details every step toward Webb’s launch and science results.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      How do we do research in zero gravity?

      Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity.

      Now, the very microgravity that we’re trying to study up there can make experiments actually really kind of difficult for a bunch of different reasons.

      First of all, stuff floats. So losing things in the ISS is a very real possibility. For example,
      there was a set of tomatoes that was harvested in 2022 put it in a bag and it floated away and we couldn’t find it for eight months.

      So to prevent this kind of thing from happening, we use a lot of different methods, such as using enclosed experiment spaces like glove boxes and glove bags. We use a lot of Velcro to stick stuff to.

      Another issue is bubbles in liquids. So, on Earth, bubbles float up, in space they don’t float up, they’ll interfere with optical measurements or stop up your microfluidics. So space experiment equipment often includes contraptions for stopping or blocking or trapping bubbles.

      A third issue is convection. So on Earth, gravity drives a process of gas mixing called convection and that helps circulate air. But without that in microgravity we worry about some of our experimental organisms and whether they’re going to get the fresh air that they need. So we might do things like adding a fan to their habitat, or if we can’t, we’ll take their habitat and put it somewhere where there might already be a fan on the ISS or in a corridor where we think they are going to be a lot of astronauts moving around and circulating the air.

      Yet another issue is the fact that a lot of the laboratory instruments we use on Earth are not designed for microgravity. So to ensure that gravity doesn’t play a factor in how they work, we might do experiments on the ground where we turn them on their side or upside down, or rotate them on a rotisserie to make sure that they keep working.

      So, as you can tell, for every experiment that we do on the International Space Station, there’s a whole team of scientists on the ground that has spent years developing the experiment design. And so I guess the answer to how we do research in microgravity is with a lot of practice and preparation.
