MAVEN Communication Issues

This time last year we were celebrating the 10th anniversary of NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft entering orbit around Mars. Today we are wondering about the future of that spacecraft after NASA lost contact with it.

As of earlier today, all NASA would say is the following:

The spacecraft and operations teams are investigating the anomaly to address the situation. More information will be shared once it becomes available.

MAVEN is part of the Mars Relay Network (MRN), which is used to transmit data from the Martian surface back to Earth. For instance, NASA’s two remaining rovers – Curiosity and Perseverance – utilize this network. Five NASA and European Space Agency spacecraft orbiting Mars are part of the MRN: MAVEN, Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, and ExoMars Trace Gas Orbiter.

The last thing we need now under this administration is a weak link to Mars since finding funds to further bolster the MRN will not be easy. So let’s hope for an easy fix.

Space Stories: Crew Returns from ISS, Isaacman Nomination Advances, and Robotic Spacecraft to Save Space Telescope

Here are some recent space-related stories of interest.

—CBS News: “3-man Crew Undocks from International Space Station, Wrapping Up 8-month Stay“

A NASA astronaut and two cosmonaut crewmates strapped into their Soyuz ferry ship and undocked from the International Space Station on Monday, heading for landing on the steppe of Kazakhstan to wrap up an eight-month mission…With Soyuz commander Sergey Ryzhikov strapped into the descent module’s center seat, flanked on his left by cosmonaut Alexey Zubritsky and on the right by NASA’s Jonny Kim, the Soyuz MS-27/73S spacecraft undocked from the lab at 8:41 p.m. ET.

—Reuters: “US Senate Committee Votes to Advance NASA Nominee Jared Isaacman“

The U.S. Senate Commerce Committee voted late on Monday to advance the nomination of billionaire private astronaut Jared Isaacman to lead NASA...Senate Commerce Committee Chair Ted Cruz said: “You are as committed to American supremacy in the final frontier as is this committee and the entire Senate. My hope is that you will be confirmed and in this role before the end of this year.” He also won support of the panel’s top Democrat, Senator Maria Cantwell.

—Indian Defence Review: “A Rescue Mission Will Save NASA’s Space Telescope Using a Rocket Dropped from a Plane“

Launched in 2004 to study gamma-ray bursts, Swift has been a crucial asset in understanding some of the most energetic events in the universe. However, over time, the spacecraft’s orbit has been decaying due to the drag from Earth’s atmosphere. As the orbit continues to degrade, the telescope is set to fall from its current 249-mile altitude unless action is taken. The problem is that Swift lacks onboard thrusters for orbit adjustments. With no replacement mission in the pipeline, NASA has turned to the private sector for a solution, and Katalyst is stepping in with a bold plan…For Neil Gehrels Swift Observatory, however, no astronauts will be involved. Instead, Katalyst will perform the rescue entirely remotely.

    Space Quote: China, the Moon, and the Military

    “Politically, China’s lunar program has demonstrated an ability to undertake cutting edge scientific programs, as demonstrated in the innovative Chang’e-4 and Chang’e-6 probes. In terms of direct military benefits, its value is more limited. China is not in a direct space race with any other state, nor is it racing to establish settlements or “space colonies.” While there are theories of how one might employ a lunar base to undertake surveillance or even kinetic operations against terrestrial targets, the costs associated with such ambitions would be enormous. Surveillance platforms on the Moon, for example, would be almost 240,000 miles from Earth. To obtain high resolution images would be enormously costly. It is not at all clear that such efforts would win a cost-benefit analysis against systems in standard earth orbits (LEO, MEO, GEO), or even air-breathing systems. Instead, the most likely military benefits are in terms of improvements in Chinese space support capabilities, thus expanding the volume of space employed for military purposes.”

    -Statement by Dean Cheng, Senior Fellow at the Potomac Institute for Policy Studies, from a hearing before the House Science, Space, and Technology Committee, Space and Aeronautics Subcommittee titled “Strategic Trajectories Assessing China’s Space Rise and the Risks to U.S. Leadership.” Mr. Cheng was one of four witnesses at the hearing.

    Television: Pluribus

    The sixth episode of Apple TV+’s Pluribus dropped this week. If you haven’t heard of the new series, you may want to check in. It starts like the movie Contact, has elements of 3 Body Problem (including the clock), and turns into The Last Man on Earth, though in this case its an angry, lone woman dealing with Invasion of the Body Snatchers.

    Interested? Oh yeah, it comes from Vince Gilligan, the same guy who also gave us on Breaking Bad and Better Call Saul. It also stars Rhea Seehorn from Better Call Saul.

    It all starts when a radio signal from a civilization about 600 light-years away is intercepted by Earth. This signal contains a RNA sequence. Of course, the dumb Earthlings find it necessary to recreate this sequence, lose control of the experiment (alla Jurassic Park), and thereby release a virus that turns the human population into the Borg. The rest of the story is how one woman and twelve other unaffected humans make their way in this new world.

    It’s an odd start to a very odd show, but it is fun and thought-provoking in its own way. It also doesn’t have simple story lines where the everyone agrees there is a problem with the new human state, or at least not all of the 13 remaining people agree. We know the collective mind seems to work in nature, be it bees or ants, so it is not impossible.

    It is too early to know whether this show has a soft landing or even a future, but it’s the type of show, like Severance, that is sure to be discussed at the virtual office water cooler.

    Okay, that’s enough references to other shows and movies. I counted eight, but I can also say that Pluribus is unique enough that none of those references really does it any justice.
