NASA's first two commercial deliveries to the moon are still on track despite the COVID-19 pandemic , according to agency leadership.

Last year, NASA hired Astrobotic and Intuitive Machines to carry science and technology projects to the surface of the moon next summer. These commercial lander missions will represent some of the earliest flights in NASA's Artemis program , which aims to land astronauts at the moon's south pole in 2024. Both companies agreed upon accepting the contracts to carry NASA payloads to the lunar surface in the summer of 2021 — but that was before COVID-19, the disease caused by a new coronavirus , froze much of the world.

"We are talking to them almost on a daily basis to assess any schedule impacts," Steven Clarke, deputy associate administrator for exploration in NASA's Science Mission Directorate, said during a presentation coordinated by the National Academies of Sciences yesterday (March 31). "Currently we are still on schedule with them."

However, as is the case with everything during a pandemic, that is subject to change. "Both providers are in full telework mode right now; no touch labor is occurring," Clarke said. "They are right now assessing what they can and can't do and what they may talk to their respective states [about]." Astrobotic is headquartered in Pennsylvania; Intuitive Machines in Texas.

For now, the payloads meant to fly on the landers are not at risk of missing their flights, Clarke added. Of the 13 payloads NASA is building for the flights , three are experiencing no or minimal impact from the COVID-19 protection measures, he said. (The landers will also carry payloads supplied by other customers.)

The rest have or will soon hit a point at which work is put on hold. "These are the payloads that are being developed on the NASA centers and as you already know we're in a mandatory telework environment ," he said, with some centers closed to nearly all on-site work.

However, Clarke said that NASA does not expect these pauses to interfere with the scheduled flights. "There is margin built into the delivery dates of these instruments to Astrobotic and Intuitive Machines," he said, and right now that schedule padding should be sufficient to accommodate delays.

One factor that NASA is watching particularly closely with regard to these payloads is the need to test instruments in specialized facilities, Clarke said. "We'll assess that once we get to that point," he said. "I'll reiterate that there is margin in the schedule for the delivery of these instruments."
