The latest podcast episode of the Planetary Society’s Planetary radio had an informative discussion about space stations, including why we need them and who should be financing them. The episode, What’s Going on with Commercial Space Stations, is a conversation between Casey Dreier, Chief of Space Policy for The Planetary Society, and Clayton Swope, Deputy Director of the Aerospace Security Project and Senior Fellow for The Center for Strategic and International Studies (CSIS).

Mr. Swope wrote an story last month for CSIS titled “NASA Changes Course on Commercial Space Stations.” In it, he notes that NASA’s recent change to its program for commercial space stations was due to greater skepticism about the private sector’s ability to make a business case for a space station and then properly construct one in a timely fashion. This is the crux of his discussion with Casey Dreier, which is fun to follow.

Should the federal government continue to take the lead on both the financing and construction of manned space stations to replace the International Space Station (ISS) once it is retired? And why do we even need another manned space station? Does it serve a commercial purpose that cannot be replicated with robots? Or is it more akin to our nation’s support and participation in the Olympics, where we can show American prowess while hopefully taking sports to a new level?

The conversation covers a fair amount of ground, while the Planetary Radio website offers a variety of background links as well as some useful information on the proposed commercial space stations, including:

  • Axiom Station,
  • Orbital Reef,
  • Starlab,
  • Cygnus spacecraft captured by Canadarm2, and
  • Sierra Space LIFE habitat.

NASA and the private sector will need to find a way to make this Earth-orbiting commercial space station a viable option before the ISS is little more than a shooting star. NASA has already killed the Moon’s space station earlier this year (aka Gateway), demonstrating that it is willing to move quickly and break things.

Here are some recent space-related stories.

—Techspot: “NASA’s Roman Space Telescope is Launching August 30, Eight Months Ahead of Schedule“

NASA is planning to launch its Nancy Grace Roman Space Telescope on August 30, a full eight months ahead of schedule and even earlier than the space agency’s previous target of September. Engineers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, are in the process of packing the telescope for its journey to Kennedy Space Center in Florida later this month. Upon arrival, it’ll go to the Payload Hazardous Servicing Facility to undergo a full post-travel inspection.

—Space News: “Astronauts Briefly Shelter in Dragon During ISS Leak Repair“

NASA instructed astronauts on the International Space Station to briefly shelter in a Dragon spacecraft June 5 as cosmonauts attempted to repair an air leak in a Russian module. Shortly after 9 a.m. Eastern, NASA Mission Control in Houston instructed the four members of Crew-12, the Crew Dragon mission that has been at the station since February, to shelter in that spacecraft. Joining them was NASA astronaut Chris Williams, who flew to the ISS last November on a Soyuz spacecraft.The move was prompted by a decision by Roscosmos to have cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev attempt to repair an air leak in a portion of the Zvezda service module known as PrK. That is a vestibule that links a docking port with the rest of the module and has had a long-running, but small, air leak.

—Sky & Telescope: “Proposed U.S. Grant Funding Rules Spark Worry, Backlash in Astronomy“

On Friday, May 29th, the United States Office of Management and Budget (OMB) released a 412-page document rewriting how federal grants should be issued and overseen across all agencies. The changes to the procedures, which were previously altered in 2024 to make the grants process clearer, were sweeping, touching on areas from international collaboration to academic publication costs. But the through line is made explicit: to align federal grant-making with “administration policies and priorities set by the President.” Immediately, it has sparked backlash from astronomers and planetary scientists, who see grave challenges for science if the rules come to fruition.

Here are some recent space-related stories.

—Ars Technica: “One Mars Spacecraft, Two Senators, and a Cloud of Questions“

NASA released a much-anticipated contract solicitation for a Mars-orbiting spacecraft late last week, kicking off what is sure to be a hotly contested and potentially controversial procurement. At issue is $700 million, already appropriated by Congress, to build a spacecraft, launch it to Mars, and once there to serve as a vehicle to relay communications between the red planet and Earth. But the stakes may be even bigger than this, including the possible resurrection of the recently canceled Mars Sample Return mission. As part of the new solicitation, NASA says it will conduct the acquisition “as a full and open competition.” But will it? That’s the question that several people involved with this procurement process are asking. And it could turn messy, quickly.

—European Spaceflight: “French Spacesuit Prototype Delivered to the International Space Station“

A European intravehicular activity (IVA) spacesuit prototype developed under a CNES-initiated programme was transported to the International Space Station (ISS) aboard a SpaceX Dragon spacecraft. The spacesuit will be tested aboard the station by ESA astronaut Sophie Adenot. The EuroSuit project was initiated by CNES in December 2023 as part of the agency’s Spaceship FR programme, which aims to foster the development of core technologies required for future crewed missions beyond low Earth orbit.

—China Global Television Network: “China to Launch Shenzhou-23 Crewed Mission to Space Station in Coming Days“

The combination of the Shenzhou-23 crewed spacecraft and the Long March-2F Y23 carrier rocket was transferred to the launchpad at Jiuquan Satellite Launch Center in northwest China on Saturday, according to the China Manned Space Agency. All facilities and equipment at the launch site are in good condition. Various pre-launch functional inspections and joint tests will be carried out as scheduled in the coming days. The launch is planned to take place in the coming days.

Update: Here is a podcast version of this story if you sometimes prefer to digest the news in this way. It is created by AI. To note, it’s not replacing anything or anyone. It’s simply offering an option if listening while driving is preferable to you. I do not use AI in the written articles. I will also start posting the latest podcasts in the sidebar.

ISS Mission Launched, Starship Launch Delayed

Delays abound, but at least one space mission successfully launched this week. After delays earlier this week, today the CRS-34 mission successfully launched towards the International Space Station (ISS). The Dragon capsule, carrying supplies for the Expedition 74 Crew on the station, is expected to dock with the ISS Sunday morning.

The first launch this year of the SpaceX Starship was not so lucky. While is was scheduled to launch today as well, it was delayed until Tuesday, May 19th. This will be the 12th test of the new rocket.

SpaceX has planned a long list of objectives related to the booster and rocket on this flight:

The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. As this is the first flight test of a significantly redesigned vehicle, the booster will not attempt a return to the launch site for catch.

The Starship upper stage will target multiple in-space and reentry objectives, including a payload deployment of 20 Starlink simulators, similar in size to next-generation Starlink V3 satellites, and two specially modified Starlink satellites. The two modified satellites will test hardware planned for Starlink V3 and will attempt to scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test. All of the deployed payloads will be on the same suborbital trajectory as Starship. A relight of a single Raptor engine while in space is also planned.

For Starship entry, a single heat shield tile has been intentionally removed to measure the aerodynamic load differences on adjacent tiles when there is a tile missing. Finally, the ship will perform experimental actions tested on previous flight tests, including a maneuver to intentionally stress the structural limits of the vehicle’s rear flaps and a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly.

It appears SpaceX is trying to make up for numerous delays with a single mission – a mission that is critical to the success of NASA’s Artemis program as well as SpaceX’s upcoming IPO.

The ISS Will Need to Wait a Little Longer for Supplies

Everything was set for a cargo mission to the International Space Station earlier today until the weather decided to mess things up.

As a result, the CRS-34 mission with its 6,500 pounds of supplies will be delayed for another day.

Here is a summary of some of the cargo going up to the station tomorrow:

  • ODYSSEY: Evaluating how well Earth-based microgravity simulators recreate space conditions.
  • STORIE: Monitoring charged particles in orbit around the Earth, which respond to space weather and can affect assets like power grids and satellites. 
  • Laplace: Studying the movement and collision of dust particles in microgravity to understand particle motion in space.
  • Green Bone: Observing how bone cells grow and develop in space on a bone scaffold made from wood.
  • SPARK: Evaluating how red blood cells and the spleen change in space for future astronauts.

Fingers crossed for better weather tomorrow.

Update: The CRS-34 launch has now been moved to Friday, May 15th.
