Podcast: The Future of Space Stations

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.

If you are looking for some images for the upcoming Fourth of July celebrations, then this week’s pic will give you everything you need. The red, white, and blue of these images from the Chandra X-ray Observatory should put you in the right spirit.

The images from the top clockwise are Cassiopeia A, the ZwCl 0024+1652 galaxy cluster, spiral galaxy NGC 4736, and nebula NGC 3603. You can learn more about each of these images at this NASA site.

Happy Fourth of July!

A Martian Rover on the Moon?

It seems NASA is looking for some shortcuts to get back on the Moon, including repurposing an earlier rover designed for Mars. The rover in question is called the Polar Rover for Observation, Mapping and In-Situ Exploration, or simply PROMISE. It is the test model for the Perseverance and Curiosity rovers currently exploring Mars.

One of the advantages of the Mars rover is its power source. Instead of relying on solar panels, the rover is powered by a nuclear battery. This will give it greater range on the Moon’s surface without having to wait for lunar daylight. Another advantage is that it is proven technology, as the two Martian rovers have demonstrated for years.

It sounds like a smart way to take something off the shelf, but one can only wonder why this is only being considered now after NASA spent more than $450 million on the Volatiles Investigating Polar Exploration Rover (VIPER) project. Was a nuclear battery ever considered for VIPER? These Martian rovers have been around for quite some time, and a nuclear reactor has been discussed as part of the Moon Base itself, so this is not a new idea.

Given this change in plans, one might expect that the contract with Blue Origin to bring the VIPER to the Moon in 2027 is no longer needed. Maybe VIPER will put on a shelf for years like PROMISE until someone comes up with a new purpose for it.

Stay tuned.

Space Stories: Swift Recovery, Saudi Space Sight-seeing Plans, and Ukrainian Reprisals in Russia

Here are some recent space-related stories.

—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.
