Chandrayaan 3 slowed down by one web of perplexing priorities
ISRO has pushed the launch of India’s Chandrayaan 3 Moon landing mission from Q1 2023 to June 2023. After the Chandrayaan 2 lander unfortunately failed to land on the Moon in 2019 during its final mission phase, ISRO has been more serious and cautious than ever prior to attempting a landing again with Chandrayaan 3. While the mission’s technological and scientific objectives haven’t changed, ISRO has made several upgrades to the Chandrayaan-2-like lander such as software improvements, strengthened legs, a couple of new sensors, and better power and communication systems to increase the likelihood of sticking the landing.
Chandrayaan 3’s launch delay, served in the unfortunately characteristic style of ISRO (officials) providing information only when asked, is the latest in a string of similarly conveyed deferrals. Just to sample a few, the mission’s launch per agency officials previously went from Late 2020 to Early 2021 to Early 2022 to Q3 2022 to Early 2023. However, I don’t think the latest delay can be attributed to the mission.
For almost a year now, ISRO officials have consistently projected tests of the lander and other mission aspects to be going well and be done before 2023. Moreover, it was in January that ISRO chief S. Somanath said that the mission’s GSLV Mk III rocket will be ready for launch later in the year—before the mission’s delay to Q1 2023. This brings us to yesterday’s successful launch of OneWeb satellites by the same Mk III.
The next loft of OneWeb satellites to orbit will also be on a Mk III in Q1 2023, which I don’t think just happens to coincide with the previously targeted launch of Chandrayaan 3. Since India can produce a Mk III roughly once every eight months on average, it appears that the country seized the opportunity to offer OneWeb prioritised rides while meeting the company’s urgent need to replace their now-terminated launch contract with Soyuz.
Sadly, this wasn’t the first time Chandrayaan 3 was deprioritized. In October 2021, the Times of India reported that the mission would be delayed due to ISRO prioritizing their Gaganyaan preparations to send humans to Earth orbit. If only that was Gaganyaan’s only snatch. India’s upcoming Venus orbiter ‘Shukrayaan‘ has been unable to secure a GSLV Mk III for launch because the vehicle will be busy serving human spaceflight missions mid-decade. Shukrayaan mission designers are thus now looking into choosing the Mk II launch vehicle, which other than delays could reduce the orbiter’s capabilities because the Mk III is India’s most powerful rocket.
Jeff Foust reports that India is working on increasing the Mk III’s production rate to an average of one every 3 months within 2–3 years so as to attract more commercial customers, and that these would be separate from the modified Mk IIIs produced for the crewed Gaganyaan program. While this could’ve been great news for India’s growing planetary ambitions, the increased availability of launch vehicles unfortunately seems to be restricted to commercial launches.
Don’t get me wrong, I’m excited about India’s growing commercial space launches going ahead—especially as a somewhat geopolitically neutral offering—but for a nation that prides itself on its purported space science achievements, India ought to be just as confident and intentional about its planetary goals and plans. While space enthusiasts around the world cheered yesterday’s OneWeb launch, as they will for Gaganyaan, none of it needs to come at the cost of uniquely valuable space science.

NASA contracts Lockheed Martin to make three more Orion lunar capsules
As part of NASA’s Artemis campaign to regularly send humans to the Moon, the agency has awarded Lockheed Martin a $1.99 billion contract to produce three more crewed Orion capsules that would fly on Artemis VI-VIII missions. This leaves six more capsules that NASA can order for future missions per the original 2019 agreement. For comparison, NASA procured the Artemis III-V capsules at $2.7 billion. The cost savings chiefly come from future reusing of many components and parts of the spacecraft structure from returned capsules during initial Artemis missions. While both entities highlighted the same, it’s important to put that in context.
In its November 2021 report, NASA’s Office of Inspector General (OIG) highlighted that a single Orion capsule launch for Artemis I and II would cost a whopping $1 billion. This doesn’t include the $300 million of the European Service Module, which critically provides propulsion, water, oxygen, thermal control and electrical power to Orion. The figure also doesn’t include the $20 billion already spent on development costs. To make matters worse, the OIG issued a highly critical report in 2020 on how NASA (mis)accounts for Orion costs. So while the roughly $667 million per Orion capsule for Artemis VI-VIII sounds like a good cost reduction, and is welcome, it’s not as effective in the grand scheme of things.
